Avoid excessive heating or cooling. Notice that it may take some time for the room temperature to reach the set temperature. Consider using the timer setting options.■Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.■Ventilate the room regularly. Using the unit for long periods of time requires attentive ventilation of the room.■Keep doors and windows closed when the unit is in operation. If the doors and windows remain open, air will flow out anddecrease the effect of cooling and heating.■Never place objects near the air inlet and the air outlet of the unit. It may reduce the effectiveness or cause the unit to stop.■Turn off the main power supply switch when not using the fan coil unit for long periods of time. Electricity is consumed so long as the switch is on. Turn off the main power supply switch in order to save energy.■Fully use the function of air flow direction adjustment if available. As cold air gathers on the floor and warm air gathers against the ceiling, it is recommended to set the air flow direction during cooling operation parallel to the ceiling and to set it downwards during heating operation. Be sure that you do not direct air flow on to the inhabitants of the room.Sealing member of air discharge outlet KDBHQ55C140Blocking parts to close one or more air outlets of the fan coil unit.Long-lifereplacement filter KAFP551K160High quality filter.Fresh air intake kit KDDQ55C140Kit which can be connected to the ventilation system inorder to supply freshair to the fan coil unit.Remote temperature sensor KRCS01-4Replacement sensor to measure temperature remotely from a location other than that in which the controller is installed.Schedule timer DST301BA51Controller with schedule timing functionality.2-way valve (ON/OFF type)EKMV2C09B7Electronic 2-way valve to control the water supply (+EKRP1C11).3-way valve (ON/OFF type)EKMV3C09B7Electronic 3-way valve to control the water supply (+EKRP1C11).Valve control PCB EKRP1C11Mandatory electronic circuit when 2-way or 3-way valve is used.Optional PCB for Modbus connection EKFCMBCB7Electronic circuit with Modbus interfaceconnections.Wiring adaptor for electrical appendices KRP4A(A)53KRP2A52Electronic circuit with additionalconnections forexternal input/outputsignals.FWCFan coil units4PW65029-1A – 05.2011User manual4 Clean your fan coil unit4Clean your fan coil unitTo clean the outside of your fan coil unit:1Switch off the fan coil unit.2Clean the outside of the fan coil unit with a soft cloth.Never clean your fan coil unit with:■any aggressive chemical solvent,■water hotter than 50°C.For maintenance of your fan coil unit, contact your installer or service company.5Solve problems with your fan coil unitWhen your fan coil unit does not function well, you can try to solve any problem with the corrective actions in this chapter.If the problem persists or is not addressed in this chapter, contact your installer or service company.Your fan coil unit does not functionIf your fan coil unit does not function:Your fan coil unit does not cool or heat wellIf your fan coil unit does not cool or heat well:Your fan coil unit leaks waterShut down the unit and contact your installer or service company.6Dispose of your fan coil unitYour fan coil unit was designed to be environment friendly.

钢铁工业的水足迹计算
中国是世界上生产钢铁最多的国家。
这个重工业的特点是重要的水耗量和数量众多的雨水有关的环境灾害。
这这项研究中，我们提出了水足迹的使用，以代替常规指标（每顿钢铁的淡水消耗(FMC)，或者每吨钢铁的水耗量（WC））。
以中国东部的一个钢厂为例，我们建立了一个水足迹计算模型，包括直接和虚拟水足迹。
然后利用系统边界分析方法提出建立一个常见、可行的工业水足迹评价方法。
具体地说，我们从生命周期评价的角度分析了钢铁行业的特点。
以水足迹计算的结果为基础进行水风险评估。
选中钢厂水消费（蓝水）足迹为2.24*107m3，包括虚拟水和2011年为6.5 * 108m3的理论水污染（灰水）足迹，表明这个企业对水环境构成了严重的威胁。
对蓝水和灰水足迹分别进行计算以提供更详细的水风险信息，而不是添加对环境没有那么重要的这两个指标。
1 简介水和能源对炼钢来说是至关重要的组成部分。
中国铁的主要生产地，因此对国际钢铁工业的发展起到了重要的作用。
表1列举了2008到2010年的钢铁主要生产国的钢产量。
2004年，中国钢铁行业水耗量是4*109m3，占了年度工业水耗量的10%。
钢铁行业通过废水排放严重影响了当地的水环境。
废水中有毒污染物种类很多，比如未溶解金属包括Cd、石油衍生物、挥发性酚和砷等等。
因此，钢铁行业严重影响了当地、地区乃至全球的水资源，并且面临很高的水风险。
现在，钢铁行业使用吨钢淡水耗量（FWC）,吨钢水耗量（WC）等指标。
吨钢淡水耗量指生产1吨钢铁消耗的淡水量。
这里面的淡水指的是进入钢厂水系统的新鲜自来水，地下水和地表水，不包括用于冷却的循环水。
吨钢水耗量值生产1吨钢铁所用的所有水，包括回收水和再生水。
FWC和WC相对来说简单实用。
但是它们仅仅反映了钢铁行业的直接水耗量，并且忽略了虚拟水耗量和废水污染。
虚拟水的概念由Allan于1998年提出，指的是输入当前进程所需要生产的水。

◆中文名称：羰基铁粉简称CIP◆英文名称：Carbonyl Iron Powder◆CAS编码：7439-89-6, UN 3089◆分子式：Fe◆分子量：55.845羰基铁粉最早由德国人发明，二战时德国的工厂被美国征收，从此美国也开始生产羰基铁粉。
目前德国BASF公司拥有世界上最大，最先进的羰基铁粉生产线。
羰基铁粉是通过CO与铁在高温高压下反应，生成5羰基铁油状物，经低压分离后得到产品。
经退火防氧化处理即可出货。
当温度为200℃，200bar的条件下羰基合成反应式如下Fe+5CO Fe(CO)5羰基铁在300℃，1bar的条件下分解为Fe和COFe(CO)5 Fe+5CO在分解过程中，因为Fe 有催化CO与CO2 反应的作用，通常采用通NH3 作为保护气体来抑制该反应。
这样一来羰基铁粉中就不可避免的会有N元素的存在。
从旋风收集器中收集到的产品一般铁含量约在97%左右，其中C和N的含量均小于1%。
由于有Fe2O3，Fe3N 等杂质的存在，同时，铁粉表明也会对CO和NH3气体有一定的吸附，这些因素造成铁粉硬度比较大，通常被称之为硬粉。
将铁粉用H2气体还原1小时，铁含量将提高到99.0%左右，同时其他元素的含量也将明显降低。
这种还原过的羰基铁粉，硬度稍低，也被称之为软粉。
羰基铁粉活性很大，正常情况放置一段时间后，因为熵的增加，会发生自动团聚。
发生团聚的铁粉颗粒度增加，颗粒粘粘，对于注射成型应用有比较大的影响。
目前市场上质量最好的羰基铁粉为德国BASF公司生产。
羰基铁粉对工艺的要求非常高，5羰基铁分解时温度变化3度，气体流量增加5%就能明显改变羰基铁粉粒度及碳含量。
外观：深灰色粉末。
◆基本用途：1.传统粉末冶金及注射成型：传统粉末冶金中的高比重合金，需要采用活性较大的铁粉作为烧结中的液相，形成较为连续的粘结相，抑制脆性相的产生，从而获得高致密度或全致密的高性能产品。

THE USER USES THIS SOFTWARE ON HIS OWN RESPONSIBILITY AND AT HIS OWN RISKS.This software was developed by Feldmann + Weynand GmbH (hereinafter F+W) in co-operation with Feldmann + Weynand Engineers GmbH (hereinafter FWC). No right or warranty is granted to the user of the software. All rights (including intellectual property) continue to belong exclusively to F+W and FWC respectively. F+W and/or FWC do not assume any liability towards the user of this software.The user of this software undertakes to hold F+W and FWC free and harmless from any claim and any direct and/or consequential damages.BY USING THIS SOFTWARE, THE USER OF THIS SOFTWARE CONFIRMS THAT HE IS AWARE OF THE ABOVE TEXT AND THAT HE THEREBY ACCEPTS ALL LE-GAL CONSEQUENCES AND OBLIGATIONS RESULTING FOR HIM THEREFORE.Note:This text is an English translation of the German disclaimer. In case of any ambiguities, the disclaimer in German shall always apply.PurposeCOP is a special software package to design joints according to the European standard EN 1993 (Eurocode 3), and here in particular EN1993-1-8.The application of the design methods for joints is rather complex and long to apply.Therefore design tools for practitioners are required for a safe and economic application of the Eurocode 3. The software COP has been developed in order to provide the de-signer a simple tool to perform a full set of design checks according to EN 1993-1-8 for the design of joints.The present documentation gives a comprehensive overview on how to install the soft-ware.Required configurationThe software is designed for Microsoft Windows. The software has been tested on Windows 10. It should also still run under Windows 7, but this is not assured. To install and run the software 500 MB memory (minimum) and 400 MB hard disk space is re-quired.The software is developed for the Microsoft .NET Framework. The .NET Framework version 4.6 or higher must be installed.Installation procedureIn order to install the COP software on a PC execute the provided installation file “COP_x.y.z_Setup”(“x.y.z”representing the actual version number). The following screen appears:Select a language for the installation procedure and press "OK" to continue.The COP Setup Wizard will start.Press “Next” to continue.On the following screen you can specify the installation folder.Press “Next” to continue.To protect your software, the licence server 'CodeMeter' is used. COP installs a third party software called CodeMeter including a service called “CodeMeter Runtime Serv-er”, hereinafter also referred to as “license server”. CodeMeter is a licensing and digital rights management system from Wibu-Systems ().As a local service, the licence server manages licences on the local PC and, at the same time, it enables as a 'network client' the access to licences available in the net-work. In addition, the licence server can be configured as a 'network server' and thus make network licences available throughout the network.If the CodeMeter software is already installed on your machine, COP will update the software if necessary. If the already installed CodeMeter software has a newer version, COP will of course skip the installation of CodeMeter.On the next screen you may decide how to configure the “license server”. In most cas-es, you would select the first option “Run as ‘local service’ or ‘network client’” (default). Only in case you bought a network license and you are installing COP on a machine that will (also) provide your license to other machines, select the second option “Run as ‘network server’”. Detailed instructions for the installation of network licences can be found below in the chapter “Installation of network licences”.Note: If the licence server is already installed on this computer and configured as a network server, the configuration cannot be changed here since the licence server may also beused by other software. However you can change the configuration later using theCodeMeter Control Center.Select the desired configuration and press “Next”to continue. The “Ready to Install” page will appear.If all settings are correct, click “Install” to start the installation process.Press "Cancel" to terminate the installation procedure here.After pressing “Install”, t he installation procedure will start to install COP on your com-puter. When done, so the following screen will appear.Click “Finish” to exit the setup program. Unless you unselect the option “Start COP now”, COP will be started after the setup program is terminated.Launch COPTo launch COP, click on the COP icon on your desktopor select “Windows Start | Feldmann + Weynand | C OP”The first time COP is started, the welcome window appears. Please confirm the dis-claimer. COP starts and displays the page “New - Create a new project”.Install / activate licenceIf you have purchased a new COP licence, you still have to install or activate this li-cence after installing COP.COP is protected to prevent illegal copying. Two types are available for the software protection:S OFTWARE-BASED PROTECTION (“LICENCE FILE”)With the software-based protection, the software is protected by installing a licence file on the local computer (or on a licence server in the case of a network licence). Please note that the software-based protection (licence file) is bound to the computer hardware and therefore cannot be transferred to another computer. Likewise, this type of protec-tion cannot be used in virtual environments.To create a new licence as software-based protection (i.e. a licence file), we need a licence request file from you. The licence request file contains characteristics of thehardware on which the licence file should be installed. Start COP and open the page “Licence” in the menu “File”. There, click on the button “Request licence...” to start the “Wizard for creating licence request files”. Select any directory in which the licence re-quest file should be saved and click on “Generate licence request file”. Please send the generated licence request file (*.WibuCmRaC) by email to ******************.1. Request licenceWe will then send you an email with your personal licence activation file, which you can install on your computer using the licence activation wizard integrated in COP. Please note: The licence file can only be installed / activated on the computer on which the licence request file was created.Save the licence activation file (*.WibuCmRaU) in any directory. Start COP and open the “Licence” page in the “File” menu. There you start the “L icence activation wizard” by clicking on the button “Activate/update licence...”. Use the “Browse” button to select the directory in which you have saved the licence activation file and then click on the “Im-port licence activation file” button.2. Activate licenceCOP will now import and activate the licence. When the process is complete, the li-cence is automatically recognised by COP and the corresponding licence information is displayed at the top of the page.H ARDWARE-BASED PROTECTION (“D ONGLE”)After purchasing a licence with hardware-based protection, we will send you a ready-configured dongle with your personal licence by post. Plug the dongle into a USB port on your computer (or, in the case of a network licence, into a USB port on the licence server). After the installation of COP, COP will automatically recognise the dongle.Note:You can use the dongle at any computer on which COP is installed, i.e. the li-cence can easily be transferred from one computer to another.Installation of network licences1.G ENERALAll the steps to install COP network licences are explained below. For this purpose, a network server and any number of local clients (network clients) will be installed. The network server provides available licences that are recognised by the network clients automatically.To install both the network server and network clients, please use the same COP setup file, which you can download at any time from the customer area on the COP website.2.N ETWORK S ERVER –I NSTALLATION AND C ONFIGURATION2.1 Software based Protection (“Licence File”)Installing SoftwareFirst install COP on a computer which you would like to use as network server. This can be any Windows machine, i.e. also a workstation. However, it should be a computerthat can always be accessed within the network. During installation, select in the setup wiz ard on page “Licence server configuration” the option “Run as ‘network server’”. Note: Please note that a software based protection (licence file) cannot be installed on virtual machines. To install COP on a virtual machine, you need a hardware based protection(dongle).Install / activate licenceIf you have purchased a new COP licence, you still have to install or activate this li-cence after installing COP. Detailed instructions can be found above in the chapter "In-stall / activate licence".Note: The network server that has now been installed can also be used as a workstation for COP. Install COP now on any number of additional computers as described below inthe chapter “3. Network Clients – Installation and configuration”.2.2 Hardware based Protection (“Dongle”)Installing SoftwareFirst install COP on a computer which you would like to use as network server. This can be any Windows machine, i.e. also a workstation. However, it should be a computer that can always be accessed within the network. During installation, select in the setup wizard on page “Licence server configuration” the option “Run as ‘network server’”. Start COP afterwards. COP will detect the dongle automatically as soon as you connect the dongle to your computer.Note: The dongle can be plugged in or removed at any time. The current state is always rec-ognised by all clients in the network. Attention! If you remove the dongle when a net-work client is using one licence of this dongle, the network client loses the licence andall program features linked to this licence will be locked. However, the project can besaved, so that no data is lost. If you plug in the dongle again, the network client will au-tomatically find the licence again, and you can continue using COP without any re-striction.3.N ETWORK C LIENTS –I NSTALLATION AND CONFIGURATIONInstall COP on each of your client computers by executing the COP setup file. In the setup wizard on the page “Licence server configuration” select the option “Run as ‘local service’ or ‘network client’” (default setting). Start CoP afterwards.In order to find the network licence of COP, the option "Search for network licences" in the menu "File" on the page "Licence" must be activated. After a new installation of COP this option is always activated. As soon as the network server is ‘visible’ for this client computer, COP will find the licence server automatically. The licence server will then immediately allocate a licence for this client, provided that not all licences are in use at this moment.。

车间设计—粉末冶金
计算说明书课题年产130吨硬质合金物料平衡计算院（系）冶金工程学院专业金属材料与热处理技术班级金属101姓名学号2012 年11 月第1章前言物料平衡计算是进行硬质合金生产前必不可少的一部分。
物料平衡计算的目的是用数学分析的方法计算每一道工序产品与生产该产品所需的原料、辅助材料之间的数量平衡关系。
物料平衡计算是确定设备、劳动力、生产面积、运输工具和各种动力等需要量的计算依据。
在冶金物料平衡计算中，通常采用两种方法：一种是按工序工艺流程“自上而下”的计算方法，另一种是“自下而上”的计算方法。
若规定出工厂的产品数量或在生产过程中若所以返回料和进行残料处理时，一般采用“自下而上”的方法，若规定出原材料处理量则采用“自上而下”的方法比较好。
“自上而下”的方法是根据生产过程的工序顺序，从第一个工序开始顺次计算各个工序的成品产量与损失量，最后综合整个生产过程中各个工序的产品数量和所以损失。
在这里，我采用的是“自下而上”的计算方法，即根据工艺流程从最终的成品产量开始向上逐步计算出整个生产过程开始所需要的原料为止。
工艺流程是：制粉→制备混合料→压制、半检→烧结、加工。
所以从产品量开始逐步向上计算。
其具体步骤为：（1）由本工序已知的产出量和产出率计算出本工序的进料量。
（2）由本工序的可返回损失率和不可返回损失率，计算出本工序的可返回损失量和不可返回损失量。
（3）由本工序的进料量和可返回料量计算出本工序的实际进料量。
（4）如果本工序实际进料量为多元组分，则应按每一组元的成分的百分数分别计算出它们的进料量。
（5）当原材料中金属含量不是100%时，一般应按原料成分直接进行计算。
为了简化计算过程也可首先按原料中所含纯金属量进行计算，然后将其计算结果根据金属在原料中的含量换算成原料的进料量。
（6）所需数字全部计算完毕后，为了清楚和验算的差错，应分别列出各工序的平衡列表。
在平衡表中，进料量总和与出料量总和应该相等。
否则说明计算有差错应予以改正使之平衡。
CT二次负载计算方法
一、保护CT运行要求1、继电保护及安全自动装置（包括微机故障录波器等）电流必须取自保护级烧组（P或D/B）。
严禁取自计量烧组（0.2或0.5/1.0/3.0）。
2、继电保护及安全自动装置CT（包括主变套管、中性点、棒间隙等）在一次最大短路电流对应的极限误差不得超过标称值（5%或10%）。
3、新建发、变电工程应使用IA制CT。
这样可允许更大的二次负载和短路电流，更能适应电网的不断发展。
4、220KV及以上系统双重化配置的两套保护装置，其电流、电压回路必须彻底独立，严禁两套保护装置之间有任何电气联系。
同一套表保护装置主、后备保护可以共享数据。
5、、110KV及以下系统配置的单套保护装置，其主、后备保护电流回路必须彻底独立。
二、电流互感器（CT）的误差由于励磁电流的存在，二次电流与换算后的一次电流不但幅值上不相等，而且相位上也不相同，这就造成了CT的误差。
由于一、二次电流的不等造成的电流误差，称为比误差；由于相位不同造成的角度误差称为相差。
根据有关规定，在允许二次负载、允许最大短路电流饱和倍数情况下，比误差不大于5%-10%，相差不大于7·。
CT的误差与流过CT的一次短路电流，CT的变比、容量、二次负载、接线方式、铁芯结构及材料等多种因素密切相关。
合格的CT是继电保护、安全稳控装置正确动作的前提条件，也是电网安全、稳定运行基本保障。
保护装置不正确动作之后；原因不明。
其中一个重要原因与CT饱和有关。
由于故障录波不完善，保护信息部完整（微机化率低活性能不完善），事故分析不到位，上述原因长期被忽视，日月积累，今年来问题在110KV及以上系统开始显露，已造成多起电网事故（包括配网事故），教训是非常深刻的。
三、减小误差的主要措施；励磁电流是造成CT的误差的主要原因，因此要减小误差就必须在减小励磁电流着手。
主要措施如下：1、在CT的设计、研发阶段采用高导磁率的铁芯材料，增大铁芯截面、缩短侧路长度，尽量提高CT的饱和倍数。
