Abstract

PURPOSE:To remove easily and thoroughly smut on the surfaces of pickled ferritic stainless steel products with no damage to the surfaces by spraying high press. water upon the surfaces to treat the smut before being dried. CONSTITUTION:When smut on the surfaces of steel poroducts is dried, it adheres too strongly to be removed with physical force such as shot cleaning. Undried smut immediately after formation, however, is not so strongly adhering to the surfaces. The udried smut is sprayed with high press. water of about 5-10 kg/cm<2> by use of a jet cleaner, etc. to remove the smut. Since this method can be carried out while conveying the products with a roller conveyor, etc., the smut can be removed rapidly and easily.
