Main applications of silicon carbon alloy

1. Deoxidizer in steel smelting

Silicon carbon alloy can be used as an effective deoxidizer in steel smelting to improve the quality of steel by removing oxides in molten steel. In the process of converter, electric furnace steelmaking and casting, silicon carbon alloy can effectively eliminate oxides in molten steel, thereby obtaining high-quality steel.

2. Alloying agent

Silicon carbon alloy can form compounds with other elements in steel to play a role in strengthening and stabilization. Silicon and carbon have an affinity for alumina and can undergo a reduction reaction on aluminum to obtain two compounds, SiAl2 and SiAl4, of which SiAl2 can be further synthesized into other Si-Al alloys.

3. Improve steel properties

Silicon carbon alloy can improve the physical properties of steel, such as increasing strength and corrosion resistance, and improve the overall quality of steel.

4. Desulfurization in slag

Sulfur in molten steel and oxides formed during the production process will precipitate in slag. Carbon in silicon carbon alloy can form sulfides with sulfur, thereby reducing the sulfur content in molten steel and the oxide content in slag.
