Abstract
A method for manufacturing pig iron in a smelting furnace including a vessel, the method including the following successive steps: loading DRI product in the vessel, melting the DRI product to form a pig iron layer topped by a slag layer, transferring the pig iron to the desulphurization station, and injecting a silicon containing material in the pig iron in the desulphurization station. It also deals with the manufacturing of steel from the iron.
