Process Practice of Refining for Free Cutting Austenite Stainless Steel

Abstract:

FreeCutting Austenite Stainless Steel 303CuS2(%:≤0.08C,8.00~10.00Ni, 17.00~19.00Cr, 1.50~3.50Cu,0.24~0.35S) is smelted by 60t Electric Arc Furnace~60t Argon Oxygen Decarburization~60t Ladle Furnace~3 Flow continuous casting machine. With decreasing basicity of AOD refining slag from 2.0 to 1.6, controlling AOD tapping slag amount and tapping temperature, the [S] in AOD tapping steel increases to 0.008%~0.012% from original 0.004%~0.006%, after feeding S-wire containing 50% S and controlling the end temperature, the yield of S increases to 60%~70% from original 30%~50%, the qualified ratio of raises from 85% to 100%.
