During The Design Of The Computer Control System Of The Strip Thickness

In the development of the national economy and the people’s production and life, thesteel plate as basic material supplies in industry, agriculture, national defense and civilproducts is widely used in, and played an important role. Steel rolling equipmentmanufacturing industry as is the important national basic industry. The production process ofsteel, strip as thin and thick plate in the main production process, its production technologyand production process is very meaningful research. Strip steel production process, thethickness of the steel plate finished product quality as one of the important indexes of therelationship between the final results of steel production. Can accurately and fast to controlthe thickness of the steel plate handled, can save the energy, shorten the production time,reduce the labor intensity, the production process is stable and reliable.Through the study of existing equipment of steel, this paper strip thickness controldesigned a set of automatic production steel rolling control system. This paper thin clad steelgroup factory Co., LTD the actual production of strip mill and control equipment as theresearch object, and through the process of steel rolling process requirement, productionprocess and equipment in the understanding and research. From the choice of hardwarecontroller, automation control network configuration, the selection of the parts, to controlstrategy and control algorithm, the design of monitoring and control system and operation,complete gives the actual production of strip thickness control system of the overall designthought. Finally the simulation analysis, find the control object model, according to theactual parameters into the transfer function, the configuration of the proper regulation PIDparameters, through to the system simulation research, in different circumstances to controlthe thickness of the steel plate handled in the study, with a final determination PID controlparameters, make the system to achieve the best working state.Design to control the thickness of the steel plate handled as the main purpose ofindustrial automatic control system, the speed of operation new TDC controller, buildingautomation control network. Finally realize the strip in the thickness of the steel platehandled accurate production for effective control, through the monitoring system of on-siteproduction process and production equipment for real-time monitoring, achieve the expectedgoal, will ultimately for enterprise to bring economic benefits and social benefits.
