ABSTRACT:
A melt reduction furnace has a flat gas-tight roof through which the oxide feeding electrode projects an extent less than usual inside the furnace to reduce its breakage risk, and a side wall gas exhaust opening above an upstanding threshold providing low-velocity gas exhaust while the threshold holds back gas flow with possible dust below the opening.
