【Abstract】 Based on the PLC control system,advanced control concepts and methods such as complex logic control and sequence control are used in the second steelmaking converter gas recovery system. The three-way switching valve,bypass valve,water seal check valve,diffusion ignition device,frequency converter and other gas recovery equipment are automatically controlled,realize the " unattended" control operation of converter gas recovery. The realization of the automatic control system will increase the efficiency of converter gas recovery,reduce the cost of steelmaking and human resources,reduce environmental pollution,and achieve high-efficiency and cleaner production.更多还原
