Mathematical model based furnace temperature optimization strategy for continuous annealing furnace

DOU Rui-feng1,WEN Zhi1,LI Qiang1,CHENG Shu-ming2,ZOU Hang2,FENG Xiao-hong2,DONG Bin2(1.Thermal Science and Energy Engineering Department,University of Science and Technology Beijing,Beijing 100083,China;2.CISID Industry Furnace Co.,LTD,Chongqing 400013,China)  
In continuous annealing furnace(CAF),the response of strip temperature to furnace temperature is severely nonlinear and hysteretic.An open simulation system for CAF temperature optimization based on heat transfer process mathematical model was put forward.The system includes a furnace temperature heuristic optimization strategy which mainly composed of loop optimization and heuristic rules for parameter adjustment.The numerical simulation showed that the strategy was approximately linearly convergent.The calculated strip temperatures were close to target temperatures, which indirectly validated the strategy.
