High Carbon Silicon
What Is High Carbon Silicon
High-carbon silicon, also known as furnace bottom silicon, silicon-carbon alloy or high-carbon ferrosilicon. It is a new type of alloy used in converter. It is also a by-product of the production of metallic silicon. The main content consists of silicon and carbon. The general requirement is between 40-70 silicon, and the carbon content is between 10-25. Other contents are: silica, phosphorus, sulfur, etc.
The product is mainly used in steel converter deoxidation, silicon, carburizing. It can be used in place of some ferrosilicon and carburizer. The experiment and production practice show that the use of high carbon ferrosilicon to deoxidize alloy process of converter can greatly reduce the cost of steelmaking per ton of steel. Thus, considerable economic benefits have been created and the market competitive advantage of steel products has been improved.
High Carbon Silicon Producing Process
High carbon ferrosilicon is a by-product of silicon metal smelting. In the process of smelting silicon metal, due to the uneven heating of the electrode in the furnace, the raw material in the bottom part of the furnace fails to reach the optimal temperature required for the production of silicon metal. The small amount of silica and carbon at the bottom did not react adequately. After a long time of accumulation under high temperature conditions, it forms a block on the bottom of the furnace. These (stable) chunks are then broken up and those with a silicon content of 60 or more are selected. It is then broken into natural blocks of 10-50mm, or small particles of 0-3mm.

Why Choose High Carbon Silicon In Steelmaking
With the increase of the proportion of converter steelmaking, the improvement of electric furnace and open furnace smelting process, the proportion of ferroalloy used as deoxidizer has increased. However, it is very uneconomical and unscientific to use expensive iron alloys as deoxidizers. If a deoxidizer with low cost and good deoxidation performance can be developed to replace some ferroalloys, it will be of great value.
High-carbon silicon is such a cost-effective compound deoxidizer. It is a by-product of the production of si metal. The silicon element of high-carbon silicon has the ability to deoxidize and desulphurize, and carbon has the ability to deoxidize. The purpose of containing these two substances in the deoxidizer is to improve the quality of the steel. In addition, because high-carbon silicon is mainly based on silicon and carbon elements, the deoxidation products generated are easy to float, do not pollute the liquid steel, and can prevent the harmful effects of inclusions such as Al2O3.
Therefore, in the process of steelmaking, such a deoxidizer as ferrosilicon alloy can be replaced. Easy to use, low cost, so more and more steel mills began to purchase high-carbon silicon.
