The hot-rolled steel coil obtains the required geometric size, compression ratio, plate shape, etc. after pickling and cold rolling, and the dirt and grease on the surface of the strip steel are cleaned by chemical, physical and electrochemical methods through the degreasing unit, which is conducive to obtaining the required finish on the surface of the steel plate after annealing, and the work hardening and the recovery of deformed grains and the required surface cleanliness are removed by annealing the annealing furnace. After annealing, enter the leveling unit to level the steel plate, and eliminate the yield platform inside the annealed steel plate through the reasonable use of tension and rolling force, so as to obtain the mechanical properties required by the customer, as well as the further improvement of the plate type, and obtain the required plate surface cleanliness through the wet leveling mode; Then through the tension leveling unit, the straightness of the plate surface and the anti-rust performance required by the customer are obtained.
