Chemical properties of silicon carbon alloy

Oxidation resistance and corrosion resistance

Silicon carbon alloy has good oxidation resistance and corrosion resistance, can remain stable at high temperatures, and has a low expansion coefficient and good thermal stability. These characteristics enable silicon carbon alloy to work and exist stably in various media.

Deoxidation performance

Silicon carbon alloy contains silicon element. After adding silicon carbon alloy in the steelmaking process, the silicon element reacts with oxygen in an affinity reaction, deoxidizes the oxygen in the molten steel, and improves the hardness and quality of the steel. In addition, the silicon element in the silicon carbon alloy has a good affinity with oxygen, so the molten steel has the characteristic of not splashing after being added.

Slag collection performance

Silicon carbon alloy also has the advantage of slag collection. Putting a certain proportion of silicon-carbon alloy into the molten steel can make the oxides in the steelmaking process quickly gather together, which is convenient for filtering and processing, making the molten steel purer, and greatly improving the density and hardness of the steel.
