Silicon carbon alloy (a new type of deoxidizer) can replace ferrosilicon, silicon carbide and carburizing agent, reduce the amount of deoxidizer, and be used in deoxidizing alloying process with stable effect. It is mainly used for diffusion deoxidation in smelting common carbon steel, which shortens oxygen time, saves energy, and has low price. It can improve steel-making efficiency, reduce raw material consumption, reduce environmental pollution, and increase carbon. It is of great value to improve comprehensive benefits. Silicon 40% - 65% carbon 15%Can be customized in accordance with customer requirements (provide a variety of content, particle size, packaging).

Silicon Carbon Alloy Ball

Silicon Carbon Alloy Ball (also called silicon‑carbon briquette / high‑carbon silicon ball) is a high‑efficiency composite metallurgical additive pressed by high‑pressure molding. It integrates deoxidation and carburization functions, widely used for steelmaking deoxidation, alloying and cast iron inoculation. It can partially or fully replace ferrosilicon, silicon carbide and carburizer to cut down your metallurgical raw‑material cost.

Compared with loose granular ferroalloys, ball‑shaped briquettes feature high mechanical strength, low dust loss during charging and transportation, fast melting speed and high element recovery rate. Chemical composition ratio and particle size can be adjusted according to customer requirements to match your furnace smelting parameters。

Key Advantages

✅ Dual‑function: Complete deoxidation and carburization in one feeding, simplify smelting process 

✅ Low dust performance: Press‑formed balls reduce flying dust, improve workshop environment and lower material waste 

✅ High recovery rate: Stable Si & C absorption into molten steel, less slag residue 

✅ Cost‑saving alternative: Replace part of ferrosilicon to reduce overall ferroalloy consumption

✅ Customizable service: Adjust Si‑C ratio, impurity limit and ball size per your technical demands

✅ Stable batch quality: Strict raw‑material inspection, consistent chemical index for every shipment
