• Maximum Charge Stability: The 10-50mm lump size ensures deep penetration into the scrap bed, preventing premature oxidation and loss to the slag.
• Intense Exothermic Yield: Harness high-energy chemical heat during dissociation to reduce electrical power consumption and shorten tap-to-tap times.
• Precision Deoxidation: Rapidly scavenges dissolved oxygen to produce cleaner steel with significantly lower non-metallic inclusion counts.
• Cost-Effective Alloying: A reliable, high-density alternative to Ferrosilicon 75 that delivers both Silicon and Carbon in a single, efficient charge.
• ZhenAn Global Logistics: Benefit from large-scale inventory and moisture-proof packaging, ensuring 88% purity from our factory to your furnace.

In high-tonnage Electric Arc Furnaces (EAF) and Basic Oxygen Furnaces (BOF), the physical integrity of additives is as vital as their chemistry. ZhenAn's 10-50mm Silicon Carbide Lumps are engineered to withstand the mechanical impact of heavy scrap charging. Unlike finer granules, these robust lumps reach the molten bath where they provide a sustained release of active elements.

By reducing iron oxides in the slag, SiC 88% lumps facilitate the creation of a consistent, stable foamy slag. This foam shields the furnace refractories from intense arc radiation, drastically reducing energy loss and extending the life of the furnace shell.

The oxidation of Silicon Carbide is more exothermic than that of standard ferrosilicon. For mills looking to increase their scrap-to-hot-metal ratio, these lumps serve as a critical "heat riser," providing the thermal energy necessary for high-productivity melting.

ZhenAn SiC 88% contains negligible sulfur compared to traditional metallurgical coke or anthracite. This allows steelmakers to hit tight sulfur specifications in high-performance alloy steels without expensive secondary desulfurization treatments.

The following table outlines the chemical and structural robustness of ZhenAn 10-50mm Silicon Carbide Lumps, optimized for heavy industrial charging.

• Minimal Fines Contamination: Our 10-50mm lumps undergo secondary screening to remove small fragments, ensuring that every ton purchased reaches the melt rather than the exhaust system.
• Supply Chain Resilience: With massive annual output, ZhenAn provides a stable buffer against market price fluctuations and guarantees rapid lead times for international shipments.
• Full Traceability: Every batch is coded and tracked from the furnace to the final packaging, ensuring your quality control team has complete peace of mind.
