Steel Enterprise Energy Management System Based on Mitsubishi PLC

Abstract

The iron and steel energy system has the nature of large scale and complex structure, which brings huge challenges to the management of the production process of enterprises. The traditional energy management system management mode is chaotic, the workload of management personnel is large, and the utilization rate of system resources is low, resulting in high cost of network construction of iron and steel enterprises. The main purpose of this paper is to analyze the application of Mitsubishi PLC in the energy management system of iron and steel enterprises. This paper mainly analyzes the problems existing in the energy management of iron and steel enterprises at this stage, puts forward the basic principles for the design of the energy management system, and uses the Mitsubishi brand PLC to carry out the system design. The research shows that in recent years, the blast furnace gas emission rate of the iron and steel enterprise has been continuously reduced from 8.12% in the first year to 0.31% in the fourth year. The effect of reducing blast furnace gas emission rate is obvious, not only fully utilizing gas resources, but also reducing pollution, and achieving good economic and social benefits.
