步进式加热炉板坯跟踪系统的开发

Development of the Slab Tracker for Walking Beam Furnace

以工控机、服务器和西门子S7-400的PLC为平台开发的鄂钢4 300 mm宽厚板加热炉电气系统,其主要功能为炉外上料辊道的自动控制、炉尾钢坯自动定位、装钢机智能确定装钢行程及动作、步进梁自动运行、出钢机智能定位取钢行程及动作,出料辊道自动运行、液压站的液压自动控制等。这些功能由PLC完成数据的采集和处理、数据传送和控制程序的运算并输出。并以西门子的Wincc作为上位机和服务器平台,实现了2台加热炉的集中显示和操作。

The electric control system of the 4 300 mm heavy and wide plate reheating furnace of Egang, consisting of industrial control computer, the server and SIEMENS S7 - 400 PLC, has the main functions such as the automatic control of the charging roller table outside the furnace, the automatic positioning of slab at the end of furnace, intelligent determination of slab charging stroke and action of the machine, automatic running of walking beam, intelligent determination of slab reclaiming stroke and action, automatic running of delivery roller table, automatic hydraulic control of the hydraulic station, and so on. The acquisition, processing and transmission of data, the calculation and output of control sequence are realized through PLC. Taking Siemens Wince as the server, the integrated display and operation of two reheating furnaces are realized.
