<p>PURPOSE:To provide cleaning method by which inclusion in a molten zinc base alloy can be efficiently removed. CONSTITUTION:By using a composition solution composed of ZnCl2 (65wt.%), NaCl (10wt.%) and NH4Cl (25wt.%), the surface of the stainless steel-made mesh filter 14 is treated, and by using this treating filter 14, the inclusion in the molten metal 15 having 10% Al-5% Cu- balance Zn sticking Fe content, is removed. Casting obtd. by using the molten metal after cleaning contains extremely little content of Fe and improved in tensile strength.</p> |
