High Carbon Silicon: Overview | Optimal Results & Best Supplier

Product Introduction

What is the High Carbon Silicon?

High Carbon Silicon , another name is H C Silicon . It is the by-product of Silicon metal, and main element are Si and C , balance are S , P, SiO2. The main markets for high carbon silicon are steelmaking, foundry and aluminium industries. In recent years, the demand for high carbon silicon has been rising year on year, and due to the rising cost of steelmaking and other industries, high carbon silicon is favoured by many metallurgical manufacturers because of its lower price than ferrosilicon and silicon metal, and by using high carbon silicon for production, manufacturers can save up to 30% of their costs and effectively improve product quality.

How to produce High Carbon Silicon?

In the process of producing Silicon metal, temperature is not enough to adequately smelting the raw material of Silicon metal in the bottom .After a long time of accumulation , there will be the by- product High carbon silicon .

Usage Of High Carbon Silicon

Improve the quality of molten steel: high carbon silicon can optimize the quality of molten steel, improve the quality of products, reduce the amount of alloy added, reduce the cost of steelmaking, and increase economic benefits.
Deoxidation: In the process of steelmaking, high-carbon silicon can quickly reduce the oxygen content in molten steel, improve the purity of molten steel, and improve the quality of steel.
Promote graphite lattication: In casting, high-carbon silicon can promote the formation of graphite lattication and spheroidal ink, improve casting quality, and reduce the occurrence of hot metal plug.
Slag collection: high-carbon silicon has the advantage of slag collection, which can make the oxide in the steelmaking process quickly clump, easy to filter, make the molten steel more pure, and greatly improve the density and hardness of steel.
Dephosphorization: In converter smelting, the role of high-carbon silicon also includes dephosphorization, decarburization and heating, which is conducive to improving the dephosphorization capacity of later slag and reducing the probability of phosphorus return.

Advantage Of High Carbon Silicon

1.Improve the quality of molten steel, improve product quality and improve product capacity.
2.Reduce the amount of alloy added, reduce steelmaking costs, and increase economic benefits.
3. Price is very low , meanwhile quality is very stable .
