The characteristics: Reduce the cost of steelmaking, increase economic efficiency, improve product quality, stable performance, improve the quality of molten steel, improve product performance, reduce the amount of alloy added, reduce the cost of steel and increase economic efficiency. Silicon carbon alloy instead of ferrosilicon, silicon carbide, recarburizer, reducing the amount of oxygen scavenger, a converter for deoxidizing alloy, the effect of stability, steel chemical composition, mechanical properties and internal quality are better than the traditional process. By testing and production shows that using Si-C alloy to converter deoxy-alloy process, greatly reduce the cost of steel, creating considerable economic benefits, improve the market competitiveness of steel. The effect of using a silicon-carbon alloy species 1, can replace ferrosilicon and carburant, FeALSi dosage is also reduced, can effectively reduce the cost of steel 6-10 yuan / ton steel 2, smelting carbon steel, special steel and some low-alloy steel, the effective recovery of effective elements.
