High carbon silicon

High carbon silicon is a cost-effective composite deoxidizer. It is easy to use, does not require a lot of investment and strict process requirements like out-of-furnace refining, and has good deoxidation performance, which can replace deoxidizers such as ferrosilicon alloys.

High carbon silicon (weight percentage): Si: 45-68%, C: 15-20%, particle size: 10-50mm, 3-10mm, 0-3mm. The silicon element Si in the high carbon silicon has the ability to deoxidize and desulfurize, and C has the ability to increase carbon and deoxidize. The purpose of containing these two substances in the deoxidizer is to improve the quality of the steel. High-carbon silicon utilizes the characteristics of silicon and carbon elements, develops the good effect of carbon elements in the deoxidation process, and obtains a composite deoxidizer based on elements with extremely strong affinity between silicon, carbon and oxygen. It has a strong deoxidizing ability. Since high-carbon silicon is mainly [Si], [C], etc., the generated deoxidation products are easy to float and remove, do not pollute the molten steel, and can prevent the harmful effects of inclusions such as Al2O3, and also have certain deoxidation [S], [ P] ability. In addition, the high content of [Si] in this deoxidizer can completely replace the current ferrosilicon alloys that consume much energy, are difficult to produce and are expensive.
