氧化铝生产流程

氧化铝生产流程控制概述(1)铝是世界上第二大常用金属，其产量和消费量仅次于钢铁，是国民经济中具有支撑作用和战略地位的金属原材料。

氧化铝是铝冶炼的主要原料，每生产1吨原铝需要消耗近2吨氧化铝。

此外，各种特殊性能的氧化铝也广泛应用于电子、石油、化工、耐火材料、陶瓷、造纸、制药等行业，因此，氧化铝生产在我国经济建设中占有十分重要的地位。

我国具有较丰富的铝土矿资源（保有储量约26亿吨），居世界第四位，具备发展铝工业的资源条件。

我国的氧化铝是在建国后伴随着电解铝的生产和发展建立起来的，八十年代以来得到了较快发展。

近年来，氧化铝价格的暴涨，激励投资者和氧化铝厂持续加速生产和扩张。

国内目前已有中铝公司所属的山东、山西、河南、中州、贵州、平果、重庆与遵义（拟建）八大铝厂，广西华银（160万吨）、阳煤集团（120万吨）、鲁能晋北、山东信发（100万吨）、三门峡开曼、东方希望（80万吨）铝业等数十个大小氧化铝厂建成或在建。

据专家估计，2006年我国的氧化铝产量将年增29-33%，达到1200-1300万吨。

氧化铝生产工艺类型氧化铝是用不同的生产方法是从铝土矿中提取出来的白色粉末。

氧化铝是典型的大型复杂流程性工业，全世界90%以上的氧化铝直接采用的是经济的拜耳法生产流程，而我国氧化铝企业因矿质的不同，而分别选用不同的生产工艺。

烧结法：适于矿石品位含硅高、难溶的、中等资源品位的一水硬铝石，流程长、工艺复杂。

我国绝大部分老的氧化铝企业多采用这一方法进行氧化铝冶炼。

山东铝厂、中州铝厂Ⅰ期、山西铝厂Ⅰ期烧结法氧化铝生产过程主要包括熟料烧成、熟料溶出、精液制备、分解和蒸发等主要的生产工序。

来自原料磨的生料浆通过回转窑烧制成易于溶出的铝酸钠熟料，再经碳分母液和一次洗液浸泡后进行溶出；此后通过赤泥分离洗涤、粗液脱硅、硅渣分离等工序生成的精液分别送至碳分和种分工序进行分解反应，析出氢氧化铝；种分母液经蒸发形成的种蒸母液送拜尔法碱液调配后给原矿浆配料；碳蒸母液则返回至原料磨配料。

电子工程师常用的10款稳压元件

电子工程师常用的10款稳压元件电子产品离不开电源，电源部分主要的功能就是将外界供给的抵押直流电（DC）通过电源管理区间（PMIC）得到各个期间所需要的电压，并满足电流和纹波以及启动顺序等要求。

主要的稳压方式有两种：（1）线性稳压 - 由工作在线性状态的三极管构成可变电阻对负载进行恒流控制，得到稳定的电压输出。

这种方式结构简单、噪声抑制度很高（达到60dB也就是1000倍以上），但一般效率比较低，要满足输入电压高于输出电压一定的压差才能够稳压，只能做降压变换。

常规的线性稳压器的压差高达2.5V，因此效率比较低，LDO线性稳压器可以做到较低的压差，比如在负载高达1A的情况下压差可以降低到350mA，当然其效率取决于具体使用的输入和输出电压的情况。

（2）开关稳压 - 由工作在开关模式的三极管和储能的电感以及平滑纹波的电容构成，以PWM或PFM的方式得到稳定的输出电压。

开关方式的好处是能够降压、升压、反压，输入电压的范围可以很宽，效率可以做到很高（有的能达到95%以上），缺点是外围电路比较复杂，外围元器件的选型比较敏感，另外高频的开关信号会在电压输出上带来较大的干扰、纹波。

虽然电源技术已经日新月异，各种高效率、高集成度、高性能的器件不断推出，但根据统计，排在前10的稳压器件仍然是比较经典的一些老器件，毕竟这些器件能够满足多数的可以看成是78xx的夫妻档，经常配对使用。

78xx得到的是对地正电压，79xx得到的是对地负电压，除此之外跟78xx一样；3.LM317/LM117上面的78xx和79xx的器件输出电压是固定的，不可调整，LM317则是输出电压可以调节的线性稳压器，也有不同的封装支持不同的电流输出，最大输出电路可以高达 1.5A；也要求2.5v以上的压差才能正常稳压工作，也具备78xx一样的优点和缺点；4. 1117系列非常经典的LDO线性稳压器，相比于78xx和LM317系列的器件，它要求的输入电压和输出电压的差值为1.2V，因此可以广泛用在电池供电的便携式系统里面，比如通过4节1.25V 的电池（满电量的时候达到5V），电量不足到4.5V电压的时候依然能够通过1117-3.3得到3.3V的稳压输出供板子上的3.3V电路工作。

Even in case of no failure project and status information are helpful which are available at the display.In the following image you can see a simplified menu overview of the diagnostic display.Figure 1: Menu structure diagnostic displayS i e m e n s A G 2016 A l l r i g h t s r e s e r v e dMenu items have no fixed numbering and can be hidden in the display depending on the connected device and current status. The menu items …Status Info“, …Status“ and …Configuration Transmission “ are shown in detail as they are more relevant for this FAQ.In the menu item …Status “ the state of all in- and outputs can be read out (e.g. “Switching output Switching ON Condition not satisfied ”). Comprehensive project information (e.g. Config-CRC, Project Engineer) can be found in the menu item …System Configuration “. In case of troubleshooting the menu item …Status Info “ is helpful. Here you can see detailed error messages and warnings. All status information which are available in Safety ES can be shown at the display. If no errors are present the menu item is empty.By means of an example with guard door monitoring and emergency stop theeasy diagnose in case of fault and no fault will be shown subsequently.Figure 2: Logic plan application exampleS i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.1 Preparation in the softwareThere is no previous engineering of the diagnosis display in the software necessary. The display can be plugged in without any effort in advance.For easy error tracking it is helpful to assign informative names to the function elements which will be shown in the diagnostic display. Furthermore all added project / hardware information can be read out in the display.2.1.1 Filling in of project informationIn …Identification“ and …Configuration“ information regarding project and hardware configuration can be filled in.Figure 3: Filling in of project informationS i e m e n s A G 2016 A l l r i g h t s r e s e r v e dFigure 4: Filling in of hardware informationIn the main system the diagnostic display can be added on system slot 1 optionally. This is only for documentation purpose and is not mandatory. All project information can be found in the diagnostic display in the menu item …System C onfiguration“.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.1.2 Preparation for detailed status informationFor easy diagnose it is advisable to name the function elements.Figure 5: Naming of function elementsBy double-clicking on the respective function element a symbolic name can be assigned in the window …properties“. T his name is displayed as further information in the diagnostic display. It is helpful to assign names for all input elements (e.g. “Emergency Stop”) as well for all output elements (e.g. “F -output”).S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.2Displaying of plant informationTo read out information at the diagnostic display an active connection to the energised basic module must be established. There mustn’t be any additional connection from the PCs/PGs via the diagnostic display to basic module. In this case the display is locked.2.2.1Reading out of project informationInformation regarding the project or hardware can be found in the menu item …System Configuration “. In the menu item …Project“ details regarding Config- CRC, Time Stamp, Release and Project Engineer are listed. Certain information are provided automatically from the system. Other information like …Project Engineer “ are only available if the corresponding fields were filled in in thesoftware (see chapter 2.1.1 Filling in of project information).In the menu item …Slot 3“ details regarding the used basic module can be found.Table 1: Project- and HardwareinformationS i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.2.2 Reading out of status informationThe full information concerning input and output elements can be found in the menu item …Status“.The elements are displayed as follows:Figure 6: Displaying of status/status infoFor this example the guard door is opened, the Emergency Stop was pushed and released but not acknowledged yet. Thus the output is not activated. These information can be read out in …Status / Input Elements “ as well …Status / Output Elements “.E-Stop 1 (symbolic name of the element),S i e m e nsA G 2016 A l l r i g h t s r e s e r v e dProtective Door (type of function element)You can read out status information which are available as element status in the Safety ES (e.g. …Timer running “, …Wa iting for Start“).S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d2.3Fault diagnosticTroubleshooting with the help of the diagnostic display will be explained by means of the application example of figure 2. There is a cross circuit between input 1 and input 2 of the emergency stop with element number 1.In case of fault detailed information can be found in the menu item “Status Info “. According to the default setting of the display the status info will be directly shown on the start screen in case of a fault (Setting adjustable in …Display Settings/ Statu s Info“)Table 2: Error messages in case of Cross-CircuitThe same procedure applies to other faults like discrepancy fault or fault within the feedback circuit. Below the element you find then the error message ‚Dis crepancy violated ‘ or ‚Feedback Circuit invalid ‘. All element messages which are available in Safety ES can be shown on the diagnostic display as well.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d3Transferring of projects by the help of the diagnostic displayThe 3SK2 diagnostic display (MLFB: 3SK2611-3AA00) has two internal memory slots at which Safety ES projects can be stored.NoteThis functionality is only available for the diagnostic display 3SK2611-3AA00. The 3RK3 diagnostic display (MLFB: 3RK3611-3AA00) has no internal memory slots and it is not possible to connect it to the 3SK2.3.1PreconditionsTo be able to transfer Safety ES projects from or to the display an activeconnection to the running basic module must be established. Furthermore it is not possible to have an additional connection from the basic module to the PG/PC via the diagnostic display. In this case the display is locked. Transferring of projects is possible with both types of 3SK2 basic modules (3SK2112, 22,5mm width/ 3SK2122, 45 mm width) as well as with the 3RK3 Advanced and 3RK3 ASIsafe.Preconditions for saving projects in the diagnostic display/ reading configurations from the deviceTo save projects within the diagnostic display 2 memory slots are available. If a project was already stored on the selected memory slot and you read out a new configuration on the same memory slot, the old one will be replaced. There are no restrictions for reading out configurations. It is possible to read out not approved and approved configurations. The device can be in configuration or safety mode. If the protection level ‚write protection‘ was selected by password for the project which will be read out from the basic module, the protection level will be copied to the configuration in the display as well.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e dHinweisThe protection level ‚Read Protection ‘ should not be activated in the basicmodule (3SK“/3RK3). In this case it is not possible to read out any configuration. Thus it is not possible to copy a project with Read Protection. This can be set after download via the Safety ES Tool.Preconditions for transferring of projects to the basic module It is possible to transmit a project to the device on condition that: - Device is running in configuring mode. - No password for device access is set.- The configuration on the basic module is not approved or there is no configuration on the basic moduleIf one of these conditions is not fulfilled the download of the project fails. In case that the download fails it is possible to download the project by resetting thebasic module to factory settings via reset button (See manual 3SK2 chapter 8.1/ manual 3RK3 chapter 6.4.4.5). Afterwards the device runs up in configuring mode and the project can be downloaded.DANGERAccidentally start possibleThe operator has to ensure that the configuration is downloaded to the correct machine, otherwise it can lead to a dangerous situation.NoteThe menu …factory settings“ in the diagnostic display refers only to the diagnostic display and not to the basic module. By executing the command the configurations in the diagnostic display among others will be deleted.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d3.2 ProcedureFor reading out a configuration from the basic module an active connection to it is necessary. Downloading a project from Safety ES to the diagnostic display is not possible without the basic module.Saving a configuration in the diagnostic displaySelect the favoured Memory Slot e.g.Table 3: Backup of a projectThe project is now saved in the selected memory slot in the diagnostic display.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e dThe project information of the saved project (Name, Project Engineer, Company, Config-CRC, Time Stamp, Approval, Cycle Time …) can be read out in the corresponding memory slot.Transmission of a configuration from the diagnostic display to the basic moduleTable 4 Write project to deviceThe configuration is now saved in the basic module.The project information of the downloaded project (Name, Project Engineer, Company, Config-CRC, Time Stamp, Approval, Cycle Time …) can be read out in “System Configuration/ Project”.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e dNoteWhen downloading an approved configuration to the basic module the device first stays in configuring mode. To change to safety mode turn off and on the basic module. After running up, the device changes automatically to safety mode.S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d3.3Use cases3.3.1 Fast device exchangeIn case of a faulty basic module the approved configuration can be transferred fast and easily to the new basic module by the help of the diagnostic display. Thus the plant operation can continue quickly.Figure 7: Fast device exchange NoteBack up the Safety ES project straight after successful commissioning of the safety application to the diagnostic display.3 Transferring of projects by the help of the diagnostic displayWorking with the 3SK2 Diagnostic displayEntry-ID: 109482844, V1.0, 04/201621S i e m e n s A G 2016 A l l r i g h t s r e s e r v e d3.3.2 Fast commissioning of same applicationBy help of the possibility to download projects from the diagnostic display the commissioning of identical machinery can be sped up. After successful function test and approving once the safety program can be downloaded to the other machinery.Figure 8: Fast commissioning of identical machinery4 Contact/SupportWorking with the 3SK2 Diagnostic displayEntry-ID: 109482844, V1.0, 04/201622Si emensA G2016Al lrigh tsr ese rv ed4 Contact/SupportSiemens AGTechnical AssistanceTel: +49 (911) 895-5900Fax : +49 (911) 895-5907Mail: ******************************** Internet: www.siemens.de/automation/support-request。

Each lighting element is a pixel, and the intensities of the pixels are contained within the intelligent digital interface input. The output is driven by patented PWM technology, which effectively guarantees high consistency of the color of the pixels. The controlcircuit consists of a signal shaping amplification circuit, a built-in constant current circuit, and a high precision RC oscillator.The data protocol being used is unipolar NRZ communication mode. The 32-bit data is transmitted from the controller to DIN of the first element, and if it is accepted it is extracted pixel to pixel. After an internal data latch, the remaining data is passed through the internal amplification circuit and sent out on the DO port to the remaining pixels. The pixel is reset after the end of DIN. Using automatic shaping forwarding technology makes the number of cascaded pixels without signal transmission only limited by signal transmission speed.The LED has a low driving voltage (which allows for environmental protection and energy saving), high brightness, scattering angle, good consistency, low power, and long life.

FeaturesThe Purposes of making OPSCO’s customers and users to have a clear understanding on the ways how touse the LED.2. DescriptionGenerally. The LED can be used the same way as other general purposed semiconductors. When using OPSCO’s TOP SMD LED, the following precautions must be taken to protect the LED.3. Cautions3.1. Dust & CleaningThis emitter has a silicone surface, There are many benefits to the silicone surface in terms of optical properties and improved reliability. However, silicone is a softer material and prone to attract dust. While a minimal amount of dust and debris on the LED will not cause significant reduction in illumination, steps should be taken to keep the emitter free of dust.These include keeping the LEDs in the manufacturer’s package prior to assembly and storing assemblies in an enclosed area after installing the emitters.Surface condition of this device may change when organic solvents such as trichloroethylene or acetone were applied.Avoid using organic solvent, it is recommended that isopropyl be used as a solvent for cleaning the LEDs.When using other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the resin of not.Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence as ultrasoniccleaning on the LEDs depends on factors such as ultrasonic power. Baking time and assembledcondition. Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur.3.2. Moisture Proof PackageIn order to avoid the absorption of moisture during transportation and storage, LED are packed in the aluminum envelop, A desiccant is included in the aluminum envelop as it absorbs moisture.Whenmoisture is absorbed into the AMT package it may vaporize and expand during soldering. There is a possibility that this can cause exfoliation of the contacts and damage to the optical characteristics of the LEDs. For this reason, the moisture proof package is used to keep moisture to a minimum in the package.3.3. StorageIn order to avoid the absorption of moisture, It is recommended to store SMD LED (in bulk or taped) in the dry box (or the desiccator) with a desiccant, Otherwise to store them in the following environment as recommended.a.Temperature: 5℃~30℃b. Humidity: 60% RH MaxIt is recommended to solder the LED as soon as possible after unpacking the aluminum envelop, But in case that the LED have to be left unused after unpacking envelop again is requested.The LED should be soldering within 1hours after opening the package.If baking is required, A baking treatment should be performed as follows:70℃±5℃for more than 24hours.Dongguang Factory : Side of fast in the east, Yucai Road, Dongshan Country, Qishi Town, Dongguan City.Dongguan Tel: (769)82632725 Dongguan Fax: (769)826327353.4. Reflow Soldering CharacteristicsIn testing, OPSCO has found S50 LEDs to be compatible with JEDEC J-STD-020C,using the parameters listed below. As a general guideline OPSCO recommends that users follow the recommended soldering profile provided by the manufacturer of solder paste used.Note that this general guideline is offered as a starting point and may require adjustment for certain PCB designs and Configurations of reflow soldering equipment.T e m p e r a t u r e (°C )Timests (Preheat)LLs maxMINT 25°C to Peakamp-upC ritical Zone T L to T PRamp downProfile FeatureLead-Based Solder Lead-Free Solder Average Ramp-Up Rate (Ts max to Tp )3℃/second max.3℃/second max.Preheat: Temperature Min (Ts min )100℃150℃Preheat: Temperature Min (Ts max )150℃200℃Preheat: Time ( ts min to ts max )60-120 seconds60-180 secondsTime Maintained Above: Temperature (T L )183 ℃217 ℃Time Maintained Above: Time (t L )60-150 seconds60-150 secondsPeak/Classification Temperature (T P )215 ℃255 ℃Time Within 5℃of Actual Peak Temperature ( tp)<10 seconds <10 seconds Ramp-Down Rate6℃/second max.6℃/second max.Time 25 ℃to Peak Temperature<6 minutes max.<6 minutes max.Note: All temperatures refer to topside of the package, measured on the package body surface.Dongguang Factory : Side of fast in the east, Yucai Road, Dongshan Country, Qishi Town, Dongguan City.Dongguan Tel: (769)82632725 Dongguan Fax: (769)826327353.5 Heat Generation:Thermal design of the end product is of paramount importance. Please consider the heat generation of theLED when making the system design. The coefficient of temperature increase per input electric power isaffected by the thermal resistance of the circuit board and density of LED placement on the board, as well as components. It is necessary to avoid in tense heat generation and operate within the maximum rating given inthis specification. The operating current should be decided after considering the ambient maximumtemperature of LEDs3.6 Electrostatic Discharge & Surge Current :Electrostatic discharge (ESD) or surge current (EOS)may damage LED.Precautions such as ESD wrist strap, ESD shoe strap or antistatic gloves must be worn whenever handling of LED.All devices, equipment and machinery must be properly grounded.It is recommended to perform electrical test to screen out ESD failures at final inspection.It is important to eliminate the possibility of surge current during circuitry design.3.7 Moisture Proof PackageCannot take any responsibility for any trouble that are caused by using the LEDs at conditions exceedingour specifications.The LED light output is strong enough to injure human eyes. Precautions must be taken to prevent lookingdirectly at the LEDs with unaided eyes for more than a few seconds.The formal specification must be exchanged and signed by both parties before large volume purchase begins.The appearance and specifications of the product may be modified for improvement without notice.Dongguang Factory : Side of fast in the east, Yucai Road, Dongshan Country, Qishi Town, Dongguan City.Dongguan Tel: (769)82632725 Dongguan Fax: (769)82632735Change HistoryFCN No.Date Rev.
