Abstract: The process flow sheet, key equipment and technology characteristics for maximum coil weight 35 t, 2 ~ 16 mm hot rolled stainless steel strip annealing and pickling line are presented. The steel grades produced in the line are austenite ,ferrite and martensite stainless steel; the strip is heated in annealing furnace by natural gas, the furnace temperature is up to 1 180 °C and the total furnace length is 96 m; the effective descaling is carried out before pickling, the pickling solutions are sulphuric acid and nitric acid + hydrofluoric acid, the maximum speed of pickling is 60 m/min, the waste water and waste acid are recovered and regenerated, and the acid mist are also recovered and treated.
