Abstract

Effect of Al deoxidizing for Spring steel during LF Process is investigated in this paper. The deoxidation system includes aluminum precipitation deoxidation when tapping, then strengthening diffuse deoxidation with adding adequate aluminum to the surface of the LF slag. It is found that the inclusions in steel have been effectively controlled, and the ultimate inclusions in the ingot is mainly CaO-MgO-Al2O3-CaS composite inclusion, the size of which is mostly less than 5μm. Al deoxidizing is helpful to improve the quality of spring steel.
