Abstract
This paper has briefly introduced the current development situation and the present mainly control method of the rolling mill, designed the control system of rolling mill based on PLC on this basis, analyzed the composition of each main part of the system, introduced its working mode particularly.
The rolling mill control system designed by this paper was made use of CPM-1A series PLC that OMRON Company produces to realize the control to the rolling mill system. The system had three major functions. It can do steel rolling, cooling and transportation for finished products. In lower program, system belt to be sprayed the cooling fluid on the surface of it to lower the temperature. After spraying the cooling fluid, the above surface of the stencil plate will form a layer of protection course. Finally, the system will transport the finished product to an appointed place, pilling them up, in order to manage in unison.
This paper combines PLC and the century star configuration software effectively to control the rolling mill automatically. PCL procedure has realized all functions of the rolling mill. PLC procedures and configuration procedures are clear. They can demonstrate every working state of the rolling mill integrally. The system running steadily and can meet each required targets, can apply to the production of realistic industry.
Keywords : Programmable controller；Configuration software; the rolling mill
