Description

Application of Silicon Carbon Alloy

Silicon carbon alloy is a subsidiary product produced in the production of metallic silicon. In the production process of metallic silicon, the raw materials are smelted in an electric furnace. Due to the uneven distribution of electrodes in some furnaces, uneven heating of the raw materials may occur. A small amount of silica at the bottom of the furnace did not completely react with raw materials such as carbon. In a high-temperature environment, after a long time accumulation, a lump-like product is formed at the bottom of the furnace. These products are silicon carbon alloy.

Introduction of Silicon Carbon Alloy

As an emerging alloy product, silicon carbon alloy has not been popularized in countries all over the world. Therefore, there are not many companies that can produce high carbon silicon. In China, the main production capacity of silicon carbon alloy is concentrated in Anyang, Henan. Kongfang metallurgical is located in this area, relying on the advantages of the material production area, and all products are sold directly by the factory, the silicon carbon alloy products provided are competitively priced. The company has many years of experience in the metallurgical refractory industry, and is proficient in the production process of silicon carbon alloy products, and can customize personalized products according to customer needs.

Material Advantages of Silicon Carbon Alloy

As a new type of composite alloy deoxidizer, silicon carbon alloy has an absolute price advantage compared to other types of deoxidizers and can replace traditional deoxidizers such as ferrosilicon powder, calcium carbide, carbon powder, alloy powder, etc. Silicon carbon alloy has stable physical and chemical properties and a good deoxidation effect. Used in the converter steelmaking process, it can quickly react with the oxygen in the molten steel to form steel slag floating on the surface of the molten steel, thereby achieving the purpose of deoxidation. Silicon carbon alloy has certain desulfurization and recarburization effects while deoxidizing, which can replace part of the recarburizer, thereby greatly reducing the cost of steelmaking.

Advantages of silicon carbon alloy used for deoxidation in the smelting process of ordinary steel, alloy steel and special steel

In converter steelmaking, silicon carbon alloy can replace ferrosilicon, silicon carbide and recarburizers, thereby effectively reducing the amount of deoxidizers and stabilizing chemical components.

The use of silicon carbon alloy as a deoxidizer in the steel smelting process can effectively shorten the reduction time, reduce the power consumption in the production process, and improve the efficiency of steelmaking at the same time.

The process of decomposition and oxidation of silicon carbon alloy in the converter will generate a lot of heat, which will increase the temperature and pressure in the furnace and provide the necessary conditions for deoxidation and desulfurization.

Silicon carbon alloy also has obvious advantages for cast iron in foundries. Cast iron generally contains 2~4% C and 1~3% Si. Carbon and silicon elements directly affect the microstructure of the cast iron process. The most abundant components in silicon carbon alloy are carbon and silicon. Using high carbon silicon as a deoxidizer, high-efficiency heating agent (Si&C: 6.58kcal/g, 1.24kcal/g) and recarburizer in the iron casting process can effectively control the input of other components and produce very few impurities.

Market Prospects of Silicon Carbon Alloy

For a long time, the recovery rate of traditional alloys has been greatly affected by converter operations. Uncertain factors such as steel output, key temperature and slag amount of steel enterprises have caused large fluctuations in the alloy composition in the finished product. These factors all lead to unstable chemical composition of smelted steel, and low pass rate of internal control indicators for finished products.

The steel industry urgently needs a new type of alloy to solve its inherent problems. The silicon carbon alloy has such advantages. With the recovery of the global economy, the production capacity of the steel industry is constantly increasing. The demand for silicon carbon alloy in steel plants is also increasing year by year. Therefore, the demand for silicon carbon alloy market is steadily increasing.
