Introduction of manganese silicon varieties and supply and demand structure
Manganese-silicon alloy is the most important variety of ferroalloys, accounting for about 1/3 of the total output of domestic ferroalloys. Manganese-silicon alloy is mainly made up of manganese ore (including manganese-rich slag), coke and silica. Among them, manganese ore is the main source of manganese element (Mn) in manganese-silicon alloy. Because manganese-silicon alloy requires high ratio of manganese to iron and manganese to phosphorus, it also needs to be used with part of manganese-rich slag with low Fe and P. The role of coke in the production of manganese silicon is the same as that of ferrosilicon, mainly used as reducing agent. Silica is the main source of silicon element (Si) in manganese-silicon alloy.
