Product Description Product DescriptionSilicon Carbide (SiC) in SteelmakingSilicon 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 componentsProduct ParametersSilicon CarbideItemSiCF.CFe2O3H2OSIC99≥99%≤0.1%≤0.1%≤0.1%SIC98≥98%≤0.25%≤0.3%≤0.3%SiC97≥97%≤0.3%≤0.4%≤0.3%SiC95≥95%≤1%≤1%≤0.3%SiC88≥88.5%≤2.8%≤3%≤0.5%SiC70≥70.5%≤8%≤3.5%≤0.5% Application in Metallurgical Industry Silicon Carbide Application in Steelmaking1.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 effectivenessPackaging & ShippingCompany ProfileMain Refractory and Abrasive Material
