Product Description

Product Description

Silicon Carbide (SiC) in Steelmaking

Silicon carbide (SiC) is primarily used in steelmaking as a high-efficiency deoxidizer, carburizer, and molten steel purifying agent.

1.High-Efficiency Composite Deoxidation

*SiC decomposes to generate SiO2 and CO gas. These products combine with free oxygen in the molten steel to form low-melting-point slag, which floats to the surface, significantly reducing oxygen content.

*Deoxidation efficiency is ~40% higher than traditional aluminum deoxidizers,

*Reduces dust emissions by 30% and slag volume by 15%.

*Shortens steelmaking time and lowers power consumption by 5%-8%.

2.Carburization & Element Recovery

*Carburizing Effect: SiC contains approximately 26%-27% carbon, enabling partial substitution for carburizers to increase molten steel carbon content37.

*Improved Alloy Recovery Rate: Enhances the absorption of alloying elements such as manganese and chromium; e.g., manganese recovery increases from 82% to 90%.

3.Molten Steel Purification & Quality Enhancement

*Defect Reduction: Lowering oxygen content reduces defects like subsurface blowholes and porosity, while improving the solidification structure of cast billets.

*Grain Refinement: Purifies harmful impurities (e.g., sulfur) in the steel, refines grain structure, and improves the surface finish of machined components

Application in Metallurgical Industry

 

Silicon Carbide Application in Steelmaking

1.Cost Optimization:
Silicon Carbide can fully replace ferrosilicon (FeSi) and partially replace carburizers, reducing FeAlSi consumption, thereby lowering overall smelting costs.

2.Operational Convenience:

*Spherical morphology reduces dusting and ensures high yield.

*Endothermic decomposition maintains positive furnace pressure, enhancing desulfurization effectiveness
