在高炉炼铁企业中，上料系统是高炉不可缺少的部分，高炉上料有料车卷扬上料和传输带上料两种。卷扬料车上料机结构紧凑，占地面积小，对中小高炉有足够的供料能力，且能实现自动控制。在中小高炉中广泛采用料车卷扬上料。我们将伟创变频器与西门子S7-200 PLC作为该套系统电气控制部分，已在江西省新余市新钢石灰窑厂1#、2#、3#、4#窑炉成功应用，2006年投产至今一切生产运作良好，系统稳定。

一 卷扬上料过程（本系统为单料车上料系统）

2.1 工作过程

高炉卷扬上料工作过程是：各种原料经过槽下自动配料后进入中间料斗，这时料车原点位置就处于料斗下面，料斗把原料放入斗车，通过称重传感器确定放料已足够时，料斗自动关闭放料气阀。（自动上料及称重系统由其它公司提供）在炉顶准备好后，料车启动。经过加速→匀速→一级减速→二级减速→到达卸料位置刹车制动→料车自动倾翻卸料→延时3S后→下行→匀速→一级减速→二级减速→到达原点刹车制动→等待装料。如此往返运行。

2.2 工作特点

料车卷扬机是料车上料机的拖动设备,根据料车运行工作过程,其特点如下：

① 能够频繁启动、制动、停车、反向、低频力矩大钢绳无抖动现象，过渡时间短。

② 系统工作稳定，无溜车现象。

③ 有失速、极限保护

④ 自动/检修切换功能。即如电梯中的快/慢走车。

⑤ 系统有记忆功能。即运行中途停电后，PLC记忆当前料车位置，来电后可继续运行。

二、系统配置

1、控制部分：

西门子S7-200PLC（40点）选用CPU224 CN系列外挂EM223 CN数字输入/输出模块 （8点输入/8点输出）

TD-200文本显示器 为用户提供一个价格低廉、功能齐全的人机界面，可显示中文故障记录。及小车上、下极限位置调整。

伟创AC60-37KW变频器一台 可通过端子组合成多达15段速度

欧姆龙同轴编码器（256脉冲点/转）与电机同轴安装 用于检测料车行走位置

制动单元/制动电阻 由于系统制动频繁，可考虑配置5KW/5欧姆线绕电阻3个串联 制动单元选用VEICH-EC系列

2、拖动部分：

30KW 8极变频电机，745r/min 减速比46:1、200W电动式抱闸、独立电源散热风扇

拖斗小车 自重1.5T，重车时可达4.5T

3、基本参考数据:整个行程37.5米、上限位36.25米、上极限位37米、下限位1米、下极限0.8米、上行减速位30米、下行减速位3米、上下行各有3段速、超速保护0.85米/秒、减速机转一圈编码器记为1.92米。

4、工作原理：所有的上行或下行限位、极限位、减速位、都由同轴编码器检测到多少点脉冲后传送给PLC，PLC通过程序内设置的各段位置累计脉冲点数再发出信号控制变频器和抱闸动作。电动抱闸延时1S打开，（防止重车下滑）停止时则与变频器同时断开。散热风扇与抱闸同时动作。
