What's The Applications Of Silicon Carbon Alloy

The core applications of silicon carbon alloys are as composite deoxidizers and silicon- and carbon-enhancing alloying agents in steelmaking, primarily replacing ferrosilicon, silicon carbide, and carbon raisers in converter/electric furnace steelmaking and casting processes.

Core Application Scenarios:

Deoxidation and Purification: Utilizing the synergistic reaction of silicon and carbon, it rapidly removes free oxygen from molten steel, generating easily floating inclusions, significantly reducing oxygen content, decreasing porosity and looseness defects, and improving steel cleanliness.

Simultaneous Alloying: It replenishes the required silicon and carbon elements in molten steel in a single step, replacing the stepwise addition of ferrosilicon and carbon raisers, simplifying the process and improving composition control precision (applicable to ordinary carbon steels and structural steels such as Q195, Q235, and HRB400).

Energy Saving and Temperature Increase: The silicon-carbon oxidation reaction releases a large amount of heat, compensating for the temperature drop in molten steel, reducing electricity and gas consumption, and shortening the smelting cycle.

Performance Optimization: It refines grain size, improves steel strength, hardness, and toughness, and enhances machinability and casting density.

Cost control: Compared to single alloy materials, it offers better cost performance, higher recycling rate, and less burn-off, effectively reducing the cost of auxiliary materials per ton of steel.
