Abstract The present invention discloses a kink of silicon-calcium-barium multi-component deoxidant and desulfurizer for smelting steel. It is characterized by that its production process includes the following steps: mixing quartz sand, barium ore, lime and carbon reducing agent according to a certain proportion, adding said mixture to graphite crucible placed in the intermediate-frequency induction furnace with magnesium lining, heating to 1700-1780 deg.c, smelting for 1.5-2 hr, melting all material, refining for 10-20 min to obtain liquid deoxidant and desulfarizer, pouring it into ingot mould, cooling and breaking to form block. Said invented product possesses excellent deoxidation and desulfurizing effect and its cost is low.
