莱钢型钢新增冷锯自动控制系统开发与应用

Development and Appliance of Automatic Control System for the New Equipped Cold Saw at Laiwu Steel Section Mill

随着莱钢的快速发展以及市场的需求,对型钢的产量要求也越来越高。在冷锯区域,锯切效率已经不能满足生产工序的要求,严重制约了生产节奏。本文主要就莱钢型钢公司中型新增活动冷锯的控制系统进行了介绍,对控制系统的硬件配置作了简单的介绍,重点描述了控制系统功能开发部分。即冷锯润滑泵控制与锯机状态控制功能,锯机原点位置防前滑优化控制和定尺控制功能,特别是对新增冷锯锯机锯切速度控制功能和轧件辊道搬送模式控制功能进行了较为详细的描述。控制系统完成投入使用后,加快了生产节奏,满足了生产需求。

Along with the quick development of Laiwu Steel and the market demands, more and more quantity of H - beams are required to be produced. At the area of Cold Saw, the efficiency of saw cutting has been could not meet with the requirement of production process, which restricted the production speed badly. This article mainly introduced the Automatic control system for the new equipped Movable Cold Saw at the Section Mill of Laiwu steel, and gave a brief introduction of the hard ware this control system configured. It prominently described the developed function of the control system, i.e. the control of Cold Saw lubricating pump, the control function of saw machine condition, and optimized control to avoid of the saw machine original position to moving forward, and fix length control function. This article also particularly described the control of the new equipped movable Cold Saw cutting speed, and the control function of Roll table convey mode. After the control system putting into use, it has speeded up the production rhythm and satisfied with the production needs well.
