Development and Application of Platform of Process Control System for Plate Heat-Treatment

The architecture and functions of the platform of process control system for the plate heat-treatment in the Special Steel Plant of Baoshan were described briefly and discussed. According to the characteristics of heat-treatment needed in production, the data communication mode and load condition among the modules were analyzed in detail to provide a conceptual design for the system software. Based on the development in laboratory test platform, the software hierarchy of process control of which the number of communication modules can be changed was built. The process control systems of heat-treating furnace with roller path and quenching machine were integrated into a PC server. Testing results showed that such a hierarchy meets requirements for the reliable, stable and extensible operation in the process control system and simplifies the debugging procedure and maintenance of the system, thus improving the utilization ratio of PC server.
