Design Ideas

Wide stainless steel hot strip line integrated with mechanical electric hydraulic equipments is a complicated large system. Automatic control system is very important for improving mill efficiency and products quality. The new equipments and technology are introduced. The characteristics of hot strip line and its requests for automation, the ideas of control system design, system structure and configuration are explained in detail. Multilevel system, 1000M high speed fabric Ethernet between levels, 640M high speed global data memory network between controllers, high speed Profibus_DP network between controller and equipments, hot machine backup strategy of L2,Tri-cyclic fabric Ethernet redundancy of L1 and other innovative design ideas,and L2 main mathematic models, L1 key control models are all applied in the system. The design ideas of this paper and integrated automatic control system has been applied on several stainless steel hot strip lines.
