Applications of Silicon Carbon Alloy

 

Steelmaking Industry: Widely used in converters, electric arc furnaces, LF refining furnaces, and medium-frequency furnaces as a deoxidizer and alloying additive.

 

Foundry Industry: Suitable for the production of gray cast iron, ductile iron, and alloy castings; improves molten iron quality and enhances the uniformity of casting microstructure.

 

Metallurgical Auxiliary Materials: Can be used in secondary refining and steel composition adjustment, serving as a partial alternative to ferrosilicon and carburizing agents.

 

Recommended Steel Grades: Suitable for ordinary carbon steel, construction steel, some low-alloy steels, and cast iron products.

 

Not Recommended Applications: For ultra-low carbon steel, ultra-clean steel, and special steel grades, it is recommended to conduct experimental evaluation based on specific process conditions.
