2. What Is Silicon Manganese (SiMn)?

Silicon manganese (SiMn) is a ferroalloy mainly composed of manganese, silicon and iron.

It is one of the most widely used alloy additives in steelmaking because it performs two important functions simultaneously:

Manganese addition

Silicon deoxidation

During steel production, silicon manganese helps remove oxygen from molten steel and improves the mechanical properties of finished steel products.

The alloy is mainly produced by smelting:

Manganese ore

Quartz (silica)

Coke

in submerged arc furnaces at high temperatures.
