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.
