定径机与主轧机线速度的匹配改进

Improving on Linear Speed Matching of Sizing Mill and Master Rolling Mill

详细介绍了鞍钢无缝钢管厂定径机系统的组成。针对存在的问题编写PLC程序,利用WINCC画面的全局变量将2台PLC的数据进行交换,实现了辊道速度调节的自动化,取得良好效果。

Present the composition of the sizing mill system of Angang Seamless Steel Pipe Plant.In view of the existing problems,PLC program was compiled.The data of two programmable logic con-trollers are exchanged by means of the global variable of WINCC screen.The automation of roll table speed regulation is realized.It has achieved good results.
