The Step-type Of The Heating Furnace Control System
Based On PLC And DCS
Abstract
Step-type of the heating furnace is one of the key equipment in the production line of rolling steel, it constitutes the main production processes of the rolling production line with the rolling unit. In order to improve the quality of products in the step-type of the heating furnace, in this paper, the research is mainly from the perspective of industrial control, it designs and explores the control system of the heating process about step-type of the heating furnace.
This article designs the control plan of the fuel burning control system, the temperature control system and the chamber pressure control the system through understanding the entire step-type heating furnace's technique of production and influencing factors,and choses its control rule and the parameter. Next-bit machine uses the software of PLC to program the software,the host computer uses the software of King View to monitor and display screen,which realizes the automatic control function of the temperature and pressure of the furnace. Finally it achieves the heating furnace movement safely, economically, the highly effective.
Key words: step-type of the heating furnace;automatic control system;PID control algorithm;PLC;DCS
