Abstract

In a blast furnace producing pig iron refining of the metal is carried out by introducing air, oxygenated air or air/water vapour through lances disposed symmetrically, perpendicularly, or obliquely to the furnace hearth. The refining agent may also be introduced through nozzles in the hearth bottom, which nozzles may lead from a plenum chamber.
