The main applications of high carbon silicon

‌The main uses of high carbon silicon include as a deoxidizer and alloy additive in steel production. ‌

High carbon silicon is a novel composite alloy deoxidizer that can replace traditional deoxidizers such as ferrosilicon powder, calcium carbide, carbon powder and alloy powder. It has stable physical and chemical properties and good deoxidation effect. It can quickly react with oxygen in molten steel to form steel slag that floats to the surface of molten steel, thereby achieving the purpose of deoxidation. In addition, high carbon silicon can also be used in converter smelting deoxidation alloying process, which can reduce the amount of deoxidizer and improve the stability of chemical composition and mechanical properties of steel. ‌

The production process of high carbon silicon is that when producing metallic silicon, the temperature near the furnace bottom and furnace wall cannot stably reach the standard temperature for completely melting metallic silicon, resulting in the metallic silicon that has not been completely chemically reacted sticking to the furnace bottom and furnace wall, thus producing high carbon silicon. Its chemical composition usually includes at least 65% silicon and 15% carbon, or at least 68% silicon and 18% carbon. ‌

In the market, high carbon silicon, as a silicon briquette with broad market prospects, has the advantages of reducing production costs and recycling resources. It can also reduce the use of alloys, reduce steelmaking costs, and improve economic benefits. In addition, high carbon silicon has high density and high purity, has almost no pollution to molten steel, and can maintain a high recovery rate and stable performance. ‌
