88% Purity Silicon Carbide Lump 10-50mm for Steelmaking Deoxidizer and Furnace Additive

• Lower Energy Consumption: Leverage the high exothermic reaction of SiC lumps to reduce electrical power requirements in EAF operations.
• Stable Slag Deoxidation: Effectively "kill" the slag and reduce FeO/MnO levels for better alloy recovery and cleaner steel.
• Optimized for Heavy Scrap: The 10-50mm lump size is designed to withstand heavy charging without being blown out by furnace fans.
• Dual-Action Chemistry: Eliminate the cost of separate ferrosilicon and high-sulfur petroleum coke with a single high-carbon SiC source.
• Guaranteed Bulk Supply: ZhenAn provides stable, large-tonnage shipments with consistent chemical sizing for global steel mills.

In large-scale steel production, material physical form is just as important as chemical purity. The 10-50mm Silicon Carbide Lump is the preferred choice for primary furnace charging. Unlike finer grains, these heavy lumps penetrate deep into the scrap charge, ensuring the reaction occurs at the heart of the melt.

As the lumps dissolve, they provide a consistent release of Silicon and Carbon:

This process not only alloys the steel but also acts as a "chemical fuel," accelerating the melting process and improving the overall productivity (tons per hour) of the furnace.

Silicon Carbide 88% lumps are added during the initial scrap basket charge. Their high density ensures they remain at the bottom of the furnace, providing a sustained deoxidation effect throughout the heat.

In Basic Oxygen Furnaces, SiC lumps can be used to balance the thermal energy. If the melt is too cold, the exothermic oxidation of SiC raises the temperature more efficiently than adding extra hot metal or scrap.

For grades requiring significant carbon pickup, SiC 88% provides a low-nitrogen, low-sulfur carbon source that is more predictable than anthracite coal, leading to tighter chemistry hits and fewer re-blows.

The following table highlights the structural and chemical robustness of ZhenAn 10-50mm Silicon Carbide Lumps.

• Minimal Dusting: Our 10-50mm lumps undergo secondary screening to ensure that fines are removed, preventing baghouse clogging and material waste.
• Refractory Protection: By reducing the oxygen potential of the slag early in the process, our SiC helps form a protective "foamy slag" that shields the furnace walls from arc radiation.
• Predictable Recovery: With a stable 88% purity, furnace operators can use standard calculation models to hit target Silicon and Carbon levels with 95% confidence.
