Dalmia - Smelting

An Isasmelt reactor is an upright-cylindrical shaped steel vessel with molten bath of slag, matte or metal (depending on the application) at the bottom of the furnace. A steel lance is lowered into the bath through a hole in the roof of the furnace, and air or oxygen-enriched air is injected through the lance into the bath.
