Product Specification
Silicon Manganese
Silicon manganese (SiMn) is an alloy composed of manganese, silicon, and iron, produced by smelting manganese ore, quartz, and coke in a submerged arc furnace. It serves as a combined deoxidizer and desulfurizer in steelmaking, improving steel strength and toughness simultaneously.
Applications
- Combined deoxidizer and desulfurizer in steelmaking
- Alloying addition to improve steel strength and toughness
- Raw material for medium- and low-carbon ferromanganese production
- Stainless steel and special alloy manufacturing
