摘要
PURPOSE: A composition for eliminating sulfur from molten steel for collecting the powder of deoxidized aluminum steel is provided to improve the reactive speed of eliminating sulfur for the deoxidized aluminum steel and to improve the efficiency of eliminating sulfur at low price. CONSTITUTION: To prepare a composition for eliminating sulfur from molten metal of deoxidized aluminum steel, 10-20wt% of CaF2 and 20-30wt% of Al dross are added to CaCO3 for being mixed. And, the composition contains calcium carbide for 50-60wt% of entire composition. Herein, the diameter of particles in the composition is under 1mm. Therefore, the composition for eliminating sulfur from molten metal of deoxidized aluminum steel is supplied by using aluminum dross as a raw material. The composition has excellent capacity for eliminating sulfur from molten metal at a low price. Herein, the aluminum dross is discharged from an aluminum refinery as a by-product.
