【Abstract】 The control system is composed of basic automation system, process control system and manufacturing execution system in Laigang heavy plate heating furnace. The paper introduced the communication between manufacturing execution system and process control system, which is based on TCP/IP socket. The communication in process control system is based on message channel technique of Microsoft.NET architecture. The communication between basic automation system and process control system is based on TCP/IP cable. After the system was put into operation, temperature fluctuation in furnace was controlled within 5 ℃, coal consumption per ton of steel was reduced by 21%, and reheating quality was improved.更多还原
