  • Prevention of blockage of charge feed tube in smelting furnace
    Patent number: 5244646
    Abstract: A furnace for the production of silicon metal or a silicon containing alloy includes a charge feed tube for supplying a silicon containing charge to a reaction zone. Silicon monoxide gas generated in the reaction zone is allowed to rise through the tube and is combined with natural gas that has been introduced into the top of the tube. The natural gas and the silicon monoxide combine to form silicon carbide which is carried back into the furnace with the charge.
