Products Description
Silicon Carbon (SiC alloy) is a cost-effective and versatile metallurgical material used primarily as a deoxidizer, carburizer, and alloying agent in steelmaking and foundry processes. It is made by smelting high-purity quartz and carbon-rich materials (such as petroleum coke or anthracite) at high temperatures in electric arc furnaces.
With its dual-functionality and excellent thermal and chemical stability, Silicon Carbon improves molten metal quality while significantly reducing raw material costs. It is ideal for use in electric arc furnaces, converters, induction furnaces, and cupola furnaces across various industries.

What Are the Main Types of Silicon Carbon Available?
Silicon Carbon comes in several types based on the ratio of Silicon to Carbon:
🔹 SiC 65/15 – High silicon content, suitable for efficient deoxidation in clean steel production.
🔹 SiC 60/20 – Balanced performance, widely used in steel mills and foundries.
🔹 SiC 55/25 – Higher carbon content, excellent for carburizing applications.
🔹 Powdered SiC – Ideal for ladle additions or precision alloying.
Each type is suited for different furnace types and metallurgical goals. We help you select the most suitable grade for your specific operation.

FAQ
Q1: Can Silicon Carbon replace Ferro Silicon and Carbon Additives?
👉 Yes. Silicon Carbon combines the benefits of both, allowing you to simplify inputs and reduce costs.
Q2: What is the typical addition rate of SiC in steelmaking?
👉 Generally, 0.2–0.5% of the molten metal weight. The rate can be adjusted based on steel type and desired composition.
Q3: Does it work in induction furnaces?
👉 Absolutely. Silicon Carbon is effective in EAFs, converters, and induction furnaces alike.
Q4: Can you customize the Si-C ratio?
👉 Yes. We offer custom grades based on your technical requirements.
Q5: What is the shelf life of Silicon Carbon?
👉 If stored in a dry, sealed environment, it remains effective for over 12 months.
