Product Introduction
Silicon Carbon Alloy (Si-C Alloy) is a high-performance metallurgical material primarily used in the steelmaking and foundry industries. It's produced by smelting high-purity quartz (SiO₂) and carbon-rich materials (such as coke or anthracite) in electric arc furnaces at high temperatures.
This alloy serves as a cost-effective substitute for traditional ferroalloys like ferrosilicon (FeSi) and carburizers, making it a preferred choice for steel mills seeking better performance at lower costs. 💰
It's not just an additive-it's an optimization tool that helps achieve higher efficiency in both deoxidation and carbon adjustment processes.

Key Features & Benefits
✨ High Deoxidation Efficiency
Quickly removes oxygen in molten steel, improving purity and reducing slag formation.
💸 Cost-Effective
Replaces both ferrosilicon and recarburizer, cutting down overall alloy cost significantly.
⚙️ Improves Steel Quality
Enhances tensile strength, wear resistance, and final surface quality.
🔥 Stable Melting Performance
Excellent fluidity, low melting point, and good chemical reactivity-ideal for modern furnaces.
🌱 Eco-Friendly Option
Lower emissions during production and use compared to multiple traditional alloys.
Application
🔩 Steelmaking Industry
Used as a multi-functional alloy additive in both EAF (Electric Arc Furnace) and BOF (Basic Oxygen Furnace) operations for carbon and silicon
adjustment.
🧱 Casting Industry
Improves graphitization in gray iron and ductile iron, leading to smoother casting processes and better product structure.
🔄 Substitute for Multiple Alloys
Can partially or fully replace FeSi, FeC, and other alloy materials depending on the metallurgy plan.
