Silico Manganese – High-Carbon Ferroalloy

Silico Manganese (SiMn) is a crucial ferroalloy in the steel industry, typically containing 60–70% manganese, 10–20% silicon, and a balance of iron. It plays a vital role as a deoxidizer and alloying element in steel production, improving steel’s hardness, strength, and corrosion resistance. It also minimizes oxygen content during the smelting process, ensuring cleaner and higher-quality end products.

Cavin Resource offers bulk-grade silico manganese produced via submerged arc furnaces, available in various specifications to meet construction, infrastructure, automotive, and tool steel requirements. Our SiMn meets ISO, ASTM, and other international metallurgical standards. With customized packaging, COA, MSDS, and global logistics, we’re ready to meet wholesale buyers’ needs across continents.

Submerged Arc Furnace Process (SAF)

1. A mix of manganese ore, coke, quartz, and fluxes is charged into a submerged arc furnace.

2. Through reduction at high temperatures, silicon and manganese reduce from their oxides and combine to form silico manganese.

3. The molten alloy is tapped and cooled into lumps, which are then crushed and sized for industrial use.

1. What is the typical composition of silico manganese?

Answer: Our SiMn alloy typically contains 65-70% manganese, 15-18% silicon, and the balance iron, with low carbon and sulfur levels depending on the grade.

2. Why is silico manganese used in steelmaking?

Answer: It acts as a deoxidizer and alloying agent, helping eliminate oxygen and sulfur, improving the mechanical properties of the steel.

3. Can I request a custom grade for specific steel applications?

Answer: Yes. Cavin Resource provides customized SiMn grades to meet specific industrial or national standards for different steel grades.

4. Is your silico manganese suitable for export?

Answer: Absolutely. All our products come with full export documentation, and we support global shipping, including port-to-port logistics and custom clearance support.
