Modeling And Simulation Of Main Driving System In Hot Strip Conitnuous Rolling Based On RT-LAB

It is certain that the main driver control system is very important for hot strip continuous rolling. Because main driver system always related with ski control, tensile force control and roll force control. Domestic Steel Corporation usually adopts experimental investigation way to research main driver system. This way not only will reduce output, but also will destroy system. So the simulation technology will be the better way to resolve this problem. In this dissertation, the dynamic simulation model of main driver system of hot continuous rolling is established. A man-machine interface system which can modify mode parameters and communicate with other simulation platform is developed. Modeling process and model parameters identify are discussed in detail. The models and software have passed the expertise appraisal and authentication. Problems on the realization of interface of RT-LAB are discussed .The work provides an active approach for the off-line simulation and optimum design of rolling mills. Main content of this dissertation includes:chapter 1: The development general situation of main driver system of hot strip continuous rolling and the application in modern industry of distributed system simulation technology are summarized.
