Abstract
A tuyere and method for discharging an agitating gas into the molten contents of an electrically heated furnace to reduce temperature and composition variations in its contents. The tuyere comprises a refractory plug and sleeve for installation into the refractory wall and shell of the furnace, and a dielectric section in the tuyere pipe outside the furnace shell to prevent electrical arcing and current flow into the gas supply piping and external supports.
