Jun 09, 2018· Silico- Manganese Silico-manganese (Si-Mn) is a metallic ferro alloy which is being used to add both silicon (Si) and manganese (Mn) as ladle addition during steelmaking. Because of its lower carbon (C) content, it is a preferred ladle addition material during making of low carbon steels.
Ferromanganese, a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO 2 and Fe 2 O 3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace.
