What Are The Main Components Of Silicon Carbon Alloy?

As a new type of alloy material, carbon-silicon alloy is widely used in the steelmaking industry, which can shorten the deoxidation time, save energy, reduce costs, improve steelmaking efficiency, reduce raw material consumption, and reduce environmental pollution. In addition, because silicon-carbon alloy also contains a certain amount of carbon, the use of silicon-carbon alloy can also increase carbon, which plays a very important role in improving the overall benefits of electric furnaces. In order to give everyone a deeper understanding of the role of silicon-carbon alloy, the main components and functions of silicon-carbon alloy are explained.

The silicon in the carbon-silicon alloy has a good deoxidizing effect on the molten steel. In addition, silicon as an alloying element in steel, its mass fraction is generally less than 0.4%, and it exists in iron or austenite, which can reduce the austenite area. Improve the annealing, normalizing, and quenching temperature, and change the hardenability of hypoeutectoid steel. There is no carbide formation in silicon, which can strongly promote the graphitization of carbon. It does not contain the formation elements of carbides, and it is easy to graphitize at a certain temperature.

For ordinary low-alloy steel, it can improve its strength, change local corrosion performance, improve hardenability and tempering resistance, and it is one of the main alloying elements of multi-alloy structure. It is widely used as a strong carbide element in silicon steel, silicon steel, tungsten, vanadium, molybdenum, niobium, chromium and other materials with a mass fraction of 0.5% to 2.8%.
