Silicomanganese production utilising local manganese ores

AbstractSilicomanganese (SiMn) is widely used in Egypt as a complex reducer and alloying addition in the production of various grades of steel due to its economic and metallurgical advantages. This work investigated the possibility of using local Egyptian manganese ores mixed with ferromanganese slag to produce SiMn alloy in a submerged arc furnace at a relatively low temperature.

Reduce Slag Carryover Reliably in Steel Production

These impurities include gaseous carbon monoxide, silicon, manganese, phosphorus and liquid oxides that combine with lime and dolomitic lime, forming steel slag. At the end of the refining operation, the liquid steel is tapped (poured) into a ladle and the steel slag remains in the vessel and is subsequently tapped into a separate slag pot.
