Introduction to Silicon Carbon Alloy

There is a very well-known "star" in the steelmaking and casting industry, that is, silicon-carbon alloy. Strictly speaking, silicon-carbon alloy is not a smelting material developed specifically, but a by-product of the production of metallic silicon. Silicon-carbon alloys in steel can play a good role in deoxidation, and silicon-carbon alloys have the functions of inoculants and nodularizers in casting, which is enough to see the importance of silicon-carbon alloys to steel-making and casting. Now silicon-carbon alloys have been It is popular in the whole steelmaking and foundry industry. It can be said that the steelmaking foundry will purchase silicon carbide alloys for production every month.

Silicon carbon alloys are often used in steelmaking furnaces. For example, as a new type of strong composite deoxidizer, it can also be used for general steel, alloy steel and special steel tempering. In addition, as a heating agent, it can also replace the traditional heating agent with higher price required in converter and open hearth steelmaking. Silicon carbon alloy is a commonly used deoxidizer with the following advantages: no hydrogen source is generated during the deoxidation process, ensuring safety and reliability; carbon and silicon are important elements that determine the function of steel, and silicon carbon alloy can not only react with oxygen in molten steel to deoxidize As a result, the remaining carbon and silicon that have not been oxidized can also be dissolved in molten steel to increase silicon and carbon, and achieve the effect of killing two birds with one stone. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation should be carried out in steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer in steelmaking for precipitation and diffusion deoxidation. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel.


The test and production use show that the use of Si-C alloy for the deoxidized alloy process of the converter greatly reduces the cost per ton of steel, creates considerable economic benefits, and improves the market competitiveness of steel.
