混合配置的PLC在邯钢7#高炉热风炉自动控制系统中的应用

Application of Mix-configured PLC to the Automatic Control System of the Hot-blast Stove of No.7 Blast Furnace in Handan Steel

本文简介了邯钢7#高炉热风炉的工艺状况，重点描述了基于Quantum PLC的热风炉本体仪控系统、基于西门子S7-400PLC（软件配置按PCS7系统模式）的热风炉热油预热控制系统和基于西门子S7与S5系列PLC混合配置的热风炉换炉电控系统的构成、软硬件配置、工作原理、主要控制功能和应用效果。

The paper simply introduces the technological conditions of the Hot-blast stove of No.7 Blast furnace in Handan Steel. The author emphatically describes Quantum PLC based process control systems of the hot-blast stove body, Siemens S7-400 PLC （software configuring in PCS7 pattern） based hot-oil preheating control system of the hot-blast stove and the heat-exchanging electric control system of the hot-blast stove based on the mix- configured system of Siemens S7 and Siemens S5 series PLC, elaborates their system constitutions, software and hardware configurations, operational principles, main control functions and applicative effects.
