The pretreatment can be divided into the following: alkaline salt melting treatment method. The alkaline melt contains % hydroxide and % salt. The proportion of the two in the molten salt shall be strict, so that the molten salt has strong oxidizing power, low melting point and small viscosity. Only the sodium halo shall be analyzed in the production process, and the content shall not be less than % (wt) It is treated in a salt bath furnace at ~ ℃ for minutes for ferritic stainless steel and minutes for austenitic stainless steel. Similarly iron oxides and spinels can also be oxidized by salt to become loose ferric oxide, which is easy to be removed during acid pickling.
