High carbon silicon is also called furnace bottom silicon,HC ferrosilicon, silicon-carbon alloy. It is a by-product of the production of metallic silicon. The content is mainly silicon. H.C silicon can replace ferrosilicon, silicon carbide, carbon raiser. Can reduce the amount of deoxidizer.

High carbon ferrosilicon chemical composition:

The main chemical components of high carbon silicon are silicon and carbon.The silicon content is between 40-70. The carbon content is between 10-25. Other contents are metal oxides and a small amount of impurities.

High carbon ferrosilicon manufacturing process

High carbon ferro silicon is a by-product of metal silicon smelting.

In the process of smelting silicon metal, it will happen that the electrode is not uniformly heated in the furnace.

As a result, the raw materials at the bottom of the furnace do not reach the optimal temperature required for the production of metallic silicon.

A small amount of silica and carbon at the bottom did not fully react. After a long period of accumulation under high temperature conditions, it will form a lump on the bottom of the furnace.

These large pieces are then broken. The parts with silicon content above 60 were selected. Crushed into natural pieces of 10-50mm, or small particles of 0-3mm. It can partially replace ferrosilicon in steel making. Used for deoxidizing molten steel, increasing silicon and carbon.

High carbon silicon uses

High carbon silicon is mainly used in the steelmaking industry.

1. As a new type of strong composite deoxidizer.

High carbon silicon is a commonly used deoxidizer with the following advantages:

<1> No hydrogen source is generated during the deoxygenation process. Ensure safety and reliability.

<2> Carbon and silicon are important elements that determine the function of steel. High carbon ferrosilicon can react with oxygen in molten steel to play a deoxidizing effect. The remaining unoxidized carbon and silicon can also be dissolved in molten steel. So as to increase the effect of silicon and carbon. Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel.

All in all, silicon carbon alloy can greatly reduce the cost of steelmaking. Compared with silicon carbide and ferrosilicon, high-carbon silicon is cheaper. But it is very easy to use. It is a key product purchased by steel manufacturers.

2. Used for general steel, alloy steel and special steel exercise.

3. As a warming agent.

When making steel, traditional heating agents are expensive. The use of high-carbon silicon can effectively reduce production costs.

High carbon fesi is more economical and practical. But be sure to find the right producer. High carbon silicon is a new type of alloy. At present, few factory produce high-carbon silicon.
