钢铁厂高炉供料自动控制系统改造设计

摘要

The feeding control systems of blast furnaces in many steel plants have the following questions: poor working environment, inaccurate feeding signal and unsafety feeding system. To solve these problems, the feeding system of a typical blast furnace is taken as an example to offer the thought of system design for automatic control, design of control mode and design scheme of PLC control system. Since the system is put into production, it has reduced operating personnel workload, improved the working environment, made blast furnace worked smoothly and ensured production safety. This design plays a good role in promoting the automatic control system to blast furnace of steel plants.%目前很多钢铁厂供料系统控制供料系统存在操作员工作环境差,上料联系信号不准确和供料生产不安全等问题.针对这些问题,现以莱典型的钢铁厂高炉供料系统为例,给出了改造设计思路、控制模式设计及PLC控制系统设计方案.该系统投入运行后,降低了操作人员工作量,改善了工人的工作环境,使高炉运行顺畅,保证了生产安全.这一设计方案在钢铁厂高炉供料控制系统中具有较好的推广价值.
