东北轻合金有限责任公司自行设计制造的环轧机是用于生产大规格铝合金环件的专用轧制设备. 这里介绍该设备的轧制原理,概述其电气控制,包括电控系统的组成,主要电控部件及其作用,各辊的驱动和轧制控制的主要参量的相互关系. 本系统以西门子S7-300系列PLC为核心,将由按钮、各种控制开关等提供的控制信息,经输入模块和现场总线传送给PLC,运算处理后经输出模块和现场总线控制各电机电磁阀工作以及送计算机数据显示. 各辊均采用直流电动机驱动,辅以ABB公司的DCS500B系列直流调速器进行调速控制,确保调速平滑、转速稳定. PLC对设备各环节各种运行状态的控制,则是通过应用软件调用与之相应的子程序来完成,对于需要对某些参量进行数学运算才能达到控制要求的控制对象,则建立了于此相适应的数学模型. 实现该设备不仅能手动也能自动高速完成对各种合金、规格环件的轧制.

The ring rolling mill made by Northeast Light Alloy Co., Ltd.is designed for producing large-size aluminum alloy rings.The rolling principle and the electrical control are introduced, in-cluding system configuration, main components, their functions, as well as the relationship between each roll's drive and main parameters of the rolling control.With Siemens S7-300 PLC as the core of the system, information is provided by buttons and control switches, transferred to PLC via input mod-ules and Profibus, processed and output via output modules and Profibus to control solenoid valves on motors and to computers for data display.Each roll is driven by a DC motor facilitated with a DCS500B DC speed regulator of ABB, to keep speed regulation smooth and rotating speed stable. PLC control on each link and state are depended on calling corresponding subprogram via application software.Mathematical models are set up for some control targets whose parameters need mathematical operation can meet control requirements.This equipment can roll rings of different alloys or sizes both in manual and automatic modes at high speed.
