The process and equipment of hot rolled strip production line have been relatively mature,but still need to be further optimized and improved.The selection of reheating furnace and the control of burning loss in typical hot rolled strip production line,the determination of the main motor speed of the roughing mill and the thickness control system of the finishing mill are taken as the research objects.Through the analysis of the influence of the furnace type on the output and the relationship be-tween the amount of iron oxide scale and the heating temperature,the suggestion of selecting the walking beam reheating furnace is put forward to avoid the limitation of the output source.Through the calculation of rolling schedule,load simulation and the price comparison of motors with different speeds,how to determine the better speed of the main motor is introduced.Through the analysis of the influence of different thickness control system on the thickness,accuracy and shape of products in the finishing mill,the suggestions on the selection of thickness control system are put forward.After the optimization of the equipment selec-tion and parameter determination,the production capacity of the hot rolled strip production line can be increased,the burning loss can be reduced,the consumption can be saved and the product quality can be improved.
