High Purity Silicon Carbide 90% SiC Lump for Steelmaking Deoxidation and Slag Reduction
Product Overview
Low impurity silicon carbide (SiC) 88% granules are widely used in the metallurgical industry as an effective steelmaking deoxidizer, carbon additive, and slag conditioning material. With balanced silicon and carbon content, metallurgical grade SiC provides strong reducing capability in molten steel, helping steel plants improve metallurgical reactions, reduce oxygen content, and stabilize chemical composition during smelting.
In modern steel production, maintaining precise control over oxygen and carbon levels is essential for producing high-quality steel. Silicon carbide 88% granules for steelmaking react quickly with oxygen in molten metal, forming stable oxides and releasing silicon and carbon into the melt. This process improves steel cleanliness, enhances alloy recovery rates, and reduces the consumption of traditional ferroalloys such as ferrosilicon.
Due to its excellent thermal stability, high hardness, and strong chemical resistance, metallurgical silicon carbide granules are suitable for use in electric arc furnaces (EAF), induction furnaces, and converter steelmaking. Many steel mills purchase bulk silicon carbide for metallurgy as a cost-effective material to optimize steel production and reduce overall alloy costs.
Product Features
- Low impurity silicon carbide 88% ensures stable chemical composition and reliable metallurgical performance.
- Dual composition of silicon and carbon provides both deoxidation and carburization functions in steelmaking.
- High thermal stability enables effective performance in high-temperature furnace environments.
- Low Fe₂O₃ and ash content support the production of cleaner molten steel.
- Uniform SiC granule size ensures consistent dissolution and predictable metallurgical reactions.
Main Functions in Steelmaking
Silicon carbide granules play several important roles in metallurgical processes:
- Steelmaking deoxidizer - removes dissolved oxygen from molten steel to improve purity.
- Carbon additive for steelmaking - increases carbon content in molten metal and improves metallurgical balance.
- Slag conditioner - improves slag fluidity and supports efficient furnace reactions.
- Ferrosilicon substitute - partially replaces FeSi, helping reduce alloy consumption and production costs.
Because of these advantages, metallurgical grade silicon carbide 88% has become a widely used auxiliary material in modern steel plants and foundries.
