Abstract
A furnace system including a main furnace for melting and reducing material to form molten metal and slag which are to be continuously discharged therefrom and provided with an outlet port formed in an upper portion of the side wall thereof, and an auxiliary furnace connected to the main furnace and communicating with the interior of the main furnace through the outlet port. The molten metal and the slag are allowed to continuously flow from the main furnace into the auxiliary furnace while maintaining the melt level in the main furnace above the level of the outlet port so as to seal the outlet port. The molten metal and the slag are discharged from the auxiliary furnace at the same rate as the increase in the amount of the molten metal and the slag in the main furnace. The auxiliary furnace may be provided with temperature control device for independently controlling the temperatures of the molten metal and the slag in the auxiliary furnace.
