How Is High Carbon Silicon Produced?

High carbon silicon has a good deoxidizer function, which can improve the non-metallic impurities such as sulfur and phosphorus in steel and improve the purity of steel. At the same time, high carbon silicon can also be used as an additive to improve cast iron structure.

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. ‌

How is high carbon silicon produced?
The production process of high carbon silicon is that when producing metallic silicon, the temperature near the bottom and wall of the furnace cannot stably reach the standard temperature for completely melting metallic silicon, resulting in the metallic silicon that has not completely reacted chemically sticking to the bottom and wall of the furnace, 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.
