Nitrogen

Nitrogen is routinely used to 'splash' slag from the bottom of the furnace to the side-walls to help extend refractory life. For bottom stirring, nitrogen can be used during initial stirring cycles to reduce argon consumption while providing stirring benefits and keeping the tuyeres open.

Bottom Stirring Technology

By injecting gases through the bottom of the vessel, mixing is greatly enhanced which enables reduced heat times and increased metal yields. Net savings on the order of $1 per ton of hot metal are well documented.
