Abstract：This paper describes 1 500 mm single rack equipment with four roller leveling, leveling control system and production patterns in Laiwu Steel. By the analying for automatic control system of leveling extension ratio (AEC) and segmentation of tension control system and effectively controlling in the setting of process parameters, control system optimization, production mode of selection, so as to improve the control precision of elongation, ensure the stability of mechanical properties and surface quality of the product after the leveling, the production increased by 26%, the elongation control precision increased by 35%.
