运卷小车设计说明书正文

第一章绪论1.1文献综述1.1.1 课题研究背景高速线材轧机以其精确的孔型设计,合理的张力及活套控制,单线无扭高速连续轧制方式,以及足够的轧机刚性结构和耐磨的轧辊材质,保证了产品具有普通轧机所难以保持的断面尺寸精度。

通常高速线材轧机的产品断面尺寸精度能达到±0.1mm(对φ5.5~8.0mm的产品而言)及±0.2mm(对φ9.0~16mm产品及盘条而言),断面不圆度不大于断面尺寸总偏差的80%。

近年来又出现了成圈前的规圆设备,能把断面尺寸偏差控制到±0.05mm。

多种形式的轧后控制冷却技术是高速线材轧机不可分割的组成部分,当今轧后控制冷却工艺与设备可以对所有钢种,甚至非铁基合金线材进行控制冷却,从而得到能满足不同需要的金属显微组织和性能。

近年来通过轧制中的水冷和相应的变形分配所形成的控制轧制工艺,与轧后控制冷却相配合,使高速线材轧机对产品显微组织及力学性能的控制水平更高。

1993年,天津天钢集团公司首先由美国摩根公司引进第五代超重负荷V型轧机,标志着我国高线轧机的技术装备与国际先进水平接轨。

其后五年间,相继又有湘钢、包钢、沙钢、昆钢、武钢、宝钢引进了同等水平的8条高线(沙钢引进两条单线轧机,武钢引进为双线轧机)。

正在建设即将投产的杭钢和安阳钢厂的单线轧机也具有同样的水平。

高线生产线采用的是液压传动,与机械传动相比,液压传动更容易实现运动参数(流量)和动力参数(压力)的控制。

而纯机械传动一般只进行有级变速,而且一般情况下体积比较大,并且布局方式和控制方式受到限制。

由于液压传动具有传递效率高,可进行恒功率输出控制,功率利用充分,系统结构简单,输出转速可以无级调速,可正反向运转,速度刚性大,动作实现容易,而且液压传动调节便捷布局灵活,尤其在高危工作环境还可以远程控制等突出优点,液压传动在现代化的工业发展中得到广泛的应用。

回顾线材轧机的演变给人们的启示是:线材轧机是朝着高速单线、无扭、自动化方向发展,以满足用户对线材产品的要求:大盘重,高精度和优良的使用性能与金相组织等,这样复二重轧机已不能适应。

User's GuideSNVA221B–February2007–Revised April2013AN-1588LM5001Evaluation Board1IntroductionThe LM5001evaluation board is designed to provide the design engineer with a fully functional isolated flyback power converter based on current mode control to evaluate the LM5001switching regulator IC.The evaluation board provides a5V output with1A current capability.The input voltage ranges from16V to42V.The design operates at250kHz,a good compromise between conversion efficiency and solution size.The printed circuit board consists of two layers of two ounce copper on FR4material with a thickness of0.062inches.This application note contains the evaluation board schematic,Bill-of-Materials(BOM) and a quick setup procedure.Refer to the LM5001High Voltage Switch Mode Regulator(SNVS484)data sheet for complete circuitdesign information.The performance of the evaluation board is as follows:Input Range:16to42VOutput Voltage:5V,±2%Output Current:0to1AFrequency of Operation:250kHzBoard Size:2.75X1.75X0.6inchesLoad Regulation:0.1%Line Regulation:0.1%Over Current LimitingAll trademarks are the property of their respective owners.1 SNVA221B–February2007–Revised

Schematic3Powering and Loading ConsiderationsRead this entire page prior to attempting to power the evaluation board.3.1Quick Setup ProcedureStep 1:Set the input source current limit to 1A.Turn off the input source.Connect the positive output of the input source to J1and the negative output to J2.Step 2:Connect the load,with 1A capability,to J3for the positive connection and J4for the negative connection.Step 3:The ENABLE pin,J7,should be left open for normal operation.Step 4:Set the input source voltage to 28V and the load to 0.1A.The load voltage should be in regulation with a nominal 5V output.Step 5:Slowly increase the load while monitoring the load voltage at J3and J4.It should remain in regulation with a nominal 5V output as the load is increased up to 1Amp.Step 6:Slowly sweep the input source voltage from 16V to 42V.The load voltage should remain in regulation with a nominal 5V output.Step 7:Temporally short the ENABLE pin (J7)to GND (J5)to check the shutdown function.Step 8:Increase the load beyond the normal range to check current limiting while the input source is set to 28V.The output current should limit at approximately 1.9A.The input source current limit should be increased for this step.Fan cooling is critical during this step.2AN-1588LM5001Evaluation BoardSNVA221B–February 2007–Revised April 2013Submit Documentation FeedbackCopyright ©2007–2013,Texas Instruments Incorporated Performance Characteristics 3.2Air FlowProlonged operation at full power and high ambient temperature will cause the thermal shutdown circuit within the regulator IC to activate.A fan with a minimum of200LFM should always be provided.3.3Powering UpUsing the ENABLE pin(J7)provided will allow powering up the input source with the current level set low.It is suggested that the load power be kept low during the first power up.Set the current limit of the input source to provide about1.5times the anticipated wattage of the load.As you remove the connection from the ENABLE pin to GND(J5),immediately check for5volts at the output.A quick efficiency check is the best way to confirm that everything is operating properly.If something isamiss you can be reasonably sure that it will affect the efficiency adversely.Few parameters can beincorrect in a switching power supply without creating losses and potentially damaging heat.3.4Over Current ProtectionThe evaluation board is configured with cycle-by-cycle over-current protection.This function is completely contained in the LM5001.The Primary current is limited to approximately1A.This equates to about1.4A load current when the input voltage is16V,and about2.1A load current when the input is42V.Thethermal stress on various circuit components is quite severe while in an overloaded condition,therefore limit the duration of the overload and provide sufficient cooling(airflow).3.5SynchronizationA SYNC pin(J6)has been provided on the evaluation board.This pin can be used to synchronize theregulator to an external clock or multiple evaluation boards can be synchronized together by connecting their SYNC pins together.Refer to the LM5001High Voltage Switch Mode Regulator(SNVS484)datasheet for complete information.3.6Flyback TopologyAn excellent introduction to the isolated flyback converter is available on the Texas Instruments website.The Application Note AN-1095(SNVA005)discusses both loop compensation with a secondary side error amplifier and the phase-shift caused by opto-couplers.4Performance CharacteristicsEfficiency PlotsFigure1shows the

HYDRAULIC SYSTEMABSTRACTHydraulic presses are machines that use liquid as working medium and are made according to the principle of PASCAL to deliver energy to achieve various process es. Hydraulic presses are metal forming machines which can compl ete various forging technology such as alignment, cold forging, cold extruding and so on. Hydraulic presses have many structural forms but more often than not they are composed of crossbeam, vertical post, work table, slide block and ejector parts. This paper is about the design of 500T hydraulic press's hydraulic system, though the condition analysis of the hydraulic press's main cylinder and ejection cylinder, we can draw their velocity diagrams and load diagrams. Then we choose basic hydraulic circuit to form the hydraulic system schematics. We must make sure the main cylinder can complete the basic working cycle of fast descending, deceleration repression, time delay of press forming, relinef-pressure return and stop, and on the other hand, ejection cylinder can realize the action of ejection, return and floating side pressing. After that, we must analyse the control process of the hydraulic system. Hydraulic s ystem's main parameters are determined and through the anal ysis and calculation of pressure, flow and other parameters, and then we can go on the choose hydraulic components and auxiliary parts such as pump , motor, filters, control valves. This design adopted the manifold block, and except that the connection of pump and hydraulic cylinder still u ses the pipes and pipe joints, the connection of other components all through the channel of the manifold block. Its structure is more compact, volume is relatively smaller, its weight is lighter without pipe connection. What'smore, it can eliminate leaka ge of tubing, connectors, vibration and noise, also, the installation, commissioning and maintenance of hydraulic systrem are convenien t, low pressure drop, and it looks more beautiful.The paper has also designed the overall layout of the hydraulic station.what is more this paper have three-dimensional graph of integrated block, hydraulic pressure station,which make it more beautiful and accessible to r eader. The hydraulic system can meet the press order cycle action requires and realize the plastic mater ial forging press, stamping cold extrusion, straightening, bending forming process and other contour machining technic through check calculation of hydraulic system pressure loss and the temperature of the hydraulic system.KEYWORDS:hydraulic press, hydraulic system, system diagram, manifold block, hydraulic station目录前言 ................................................... 错误!未定义书签。

W5100硬件设计指导手册

W5100 Layout Guide1. GoalMake a low noise and stable environment for W5100 working.Reduce the possibility of EMI, EMC.Make a better circuit for W5100 by simplifying the signal trace.Figure 1Block A and B may be better placed as close to magnetic as possible. Let the trace between W5100 and magnetic as short as possible, and keep the Tx+/-(So as Rx+/-) signal traces to be symmetry. The traces should not be too long and 12cm will be the maximum of path’s length. Besides, the distance between RJ-45 and magnetic should be as short as possible.Crystal shouldn’t be placed close to Input /Output ports, edge of PCB board and magnetic devices. The most important thing is that crystal should not be placed close to high-frequency devices or traces, such as MII interface signals, Tx+/-, Rx+/- and Power signals.3. Power and Ground PlaneIt is better that do not try to partition GND at all.No power and GND planes can be underneath the isolated area for the RJ-45 connector and magnetic. Also RJ-45 connector has its isolated GND (Chassis GND) to connect to RJ-45’s case.Try to keep the GND plane as large as possible.4. Trace RoutingAvoid right angle signal trace:For Tx+/−, Rx+/− traces:Avoid signal noise or loss on these traces.Tx+ & Tx- should be equal length to each other. Rx+ & Rx- should be equal length to each other.The line width and distance between Tx+/− and Rx+/− :TXOP TXONRXIPRXINLLD : Line width is as wide as possible in the range of (6mil ~ 12 mil), ex: 8mil. L : Width between differential pair should be small, ex: 4mil.W : Isolation width between TX+/- and RX+/- is as wide as possible, ex: 30mil.GND used as isolation is recommended.K : Isolation width between TX/RX and noisy signal/power is as wide as possible,ex: 30mil. GND used as isolation is recommended.For W & K need better isolation, ex: shielding with GND.Try to avoid via for TX+/-, RX+/- traces. Via will degrade signal quality.Try to avoid digital signals (like Clocks or MII signal traces) interfere with analog signals(like Tx+/-, Rx+/- traces) and power lines. Never running noisy digital signals in parallel with TX+/- and RX+/-.The traces of power, ground, and those need de-couple cap should be shorter and wider.For some critical signals, clock and the other high speed signal traces should be as short and wide as possible. (Surely that is compared with normal signal traces.) And it’s better having the GND plane under them, and it is even better with the GND plane around it.De-couple cap should be placed as close to IC as possible, and the traces should be short.Try to keep the distance between Tx+/- & Rx+/- differential pairs for good isolation.When these two pair of traces run together in parallel, don’t place them too close for unwanted interference. Shielding by GND planes can get a better isolation to these two differential pairs.The signal trace length difference between Tx+ and Tx- (Same as Rx+ and Rx-) should be kept as small as possible, better within 1 inch.5. For better analog performanceBoth Analog GND pins and Digital GND pins must maintain a good GND return path.One GND plane is recommended.When using 25MHz crystal as clock source, the spec of crystal is better under 50ppm 6. ESD ProtectingFor ESD protection, we suggest to keep a distance(D) at least 80 mil for good isolation, which avoid ESD energy jumping by traces nearby IC. (See Figure 1)。

余热锅炉设计说明书1、概述(总体结构如下图)余热锅炉采用单锅筒自然循环,集中下降管,三垂直烟道+尾部水平烟道布置,全悬吊结构,室内布置。

余热锅炉由锅筒(含内部装置)、水管系统、上升管系统、下降管系统、一、二级蒸发管束、过热器系统(含减温器系统)、省煤器系统、一、二级蒸汽-空气预热器系统、吊挂系统、汽水管路系统、给水系统、钢结构(喷砂、喷漆、防腐)、平台扶锑(镀锌栅格、喷砂、防腐)、刚性梁、膨胀系统、密封系统、门类杂件、热工仪表等组成。

整个余热锅炉均采用轻型炉墙结构,内部有耐高温、抗磨、抗腐材料,外部有保温、防腐材料,炉墙外还包覆彩色的外护板。

在炉排的上方,布置有由一个覆以sic耐火、耐磨、抗腐材料内衬的膜式水冷壁组成的垂直辐射烟道和二个未覆以耐火材料内衬的膜式水冷壁组成的垂直辐射烟道。

在水平段布置有蒸发受热面、一级蒸发管束、过热器、最终蒸发管束。

尾部布置三级省煤器。

共包含四个回程:一回程:垂直辐射段,由内衬耐火材料的膜式蒸发受热面组成,耐火材料一直覆盖到本回程的出口。

二回程:垂直辐射段,由膜式蒸发受热面组成。

三回程:垂直辐射段,由膜式蒸发受热面组成。

四回程:水平对流段,由膜式蒸发受热面、一、二级蒸发管束,过热器、减温器及省煤器组成,省煤器部位采用轻型护板式炉墙组成。

锅炉所产生蒸汽的温度由过热器减温器控制。

在整个操作过程中,过热器入口的烟气温度保持在650︒C以下。

总之余热锅炉与焚烧炉配合良好,本身钢结构计算稳妥,各受热面配置合理,水循环良好,可确保锅炉安全、稳定、长期运行,且一定的超负荷能力。

同时也充分考虑了今后的维修保养工作。

2、烟气侧特点说明余热锅炉的第一通道是二燃室,二燃室的空间设计充分考虑最优气流分布与锅炉容量。

由炉排燃烧产生的热烟气进入二燃室。

在入口处注入二次空气,使烟气充分燃烧,保证低排放。

二燃室的体积保证烟气在正常操作时,在高于850︒C 的区域停留时间不低于2秒。

二燃室配备了助燃燃烧器,确保炉膛温度不低于850︒C。

二次空气经过流量优化后涡流喷射注入二燃室,凭借二次风喷嘴的分布在二燃室内产生涡流,进一步改善操作状况。

由于涡流的作用,气流中温度、速度和浓度方面都呈均匀分布。

温度、速度和浓度的峰值都被极小化,达到:提高烟气的燃烬程度使二燃室温度的均匀分布降低一氧化碳的浓度70%(约15mg/Nm3)减少对无防护的加热表面造成腐蚀的风险减少二恶英的形成为SNCR脱氮系统提供最优的反应环境第一通道从焚烧炉出口开始,为垂直布置,辐射换热面。

为保护水冷壁和满足烟气在850°C停留2秒以上,第一通道内壁敷设耐火材料。

为保障第一通道膜式水冷壁与焚烧炉体的相对膨胀,两者间采用大型膨胀节联接。

由于焚烧炉体为适宜中国垃圾特点的风冷式结构,出口烟温相对较高,因此膨胀节采用了耐高温、耐磨、耐腐蚀的金属材料。

第二、三通道采用水冷结构,内壁不敷设耐火材料。

第四通道为水平布置,其侧墙采用水冷壁结构至对流蒸发屏末端,省煤器区域侧墙则采用护板炉墙。

汽包布置在炉外,垂直烟道的上方。

下降管接至各蒸发段下集箱。

焚烧炉上部的锅炉辐射受热面为膜式结构,水冷壁从二次风喷口和辅助油燃烧器之后的焚烧炉出口开始。

水冷壁管端部接至共用集箱,再通过引出管接至汽包。

在第一通道的顶部,烟气转向180度流向第二通道。

在第二通道,烟气向下流动。

在第二、三通道的下部布置为水冷漏斗,用来收集锅炉飞灰。

在第四通道,布置对流传热管束。

第一级受热面时保护性蒸发屏,用来使烟气在进入末级过热器之前,将烟温降至650°C以下。

在保护性蒸发屏后的水平通道内,布置有三级过热器,第二级对流蒸发屏和三级省煤器。

3汽水侧特点说明锅炉给水经加热、除氧,给水温度130°C。

为了调节控制锅炉出口烟气温度,将给水在进入第一级省煤器前,设一可调旁路进入汽包内将给水预热。

省煤器分二级布置。

给水进入锅筒前,在省煤器内被加热至距饱和温度最小10°C以下。

省煤器给水从锅筒水空间引入。

锅筒内部装置能满足在所有负荷范围内,蒸汽品质达到要求。

所有蒸发受热面均采用自然循环原理,不同的蒸发段由不同的下降管从锅筒引入,汽水混合物由引出管引入锅筒。

为防止锅筒超压运行,锅筒上安装安全阀,安全阀排汽管需配置消声器。

蒸汽导出锅筒前,经过除雾器,避免蒸汽带水进入过热器。

过热器系统设置为三级对流管束。

为了控制调节蒸汽温度,在两级过热器间布置减温器。

一级减温器布置在第一、二级过热器间,以控制二级过热器出口蒸汽温度。

在第二、三级过热器间布置第二级减温器,以控制锅炉出口蒸汽温度不超过450°C(偏差+3、-5°C)。
