  • Patent number: 5401464
    Abstract: Manganese or silicon carbide is formed in a solid state reaction by mixing manganese or silicon oxide particles with carbonaceous material (e.g., coke) particles. The materials may be formed into agglomerates including excess carbonaceous material and heated in a suitable reactor vessel. An iron source, such as pig iron and/or iron scrap, can also be added. In that case, the manganese or silicon carbide dissolves in molten iron to produce ferrosilicon or ferromanganese alloys.
    Type: Grant

  • Patent number: 4309024
    Abstract: A cupola for the melting of metal is provided with an auxiliary gas generator which supplies through the forehearth hot carbon monoxide rich gas to the bottom of the cupola as a source of heat. The heat of the gases maintains the cupola hearth and forehearth hot. Ordinary coal, or coke breeze or any other carbonaceous fuel may be burned in the generator. Additionally, the cupola may be allowed to go to zero output without cooling off.

  • Patent number: 4140480
    Abstract: A pilot flame to be positioned close to the charge opening of a cupola which uses carbon monoxide as a fuel in the presence of a fresh supply of combustion air, such carbon monoxide being drawn off from a position on the cupola where the temperature is above the self-ignition temperature of the carbon monoxide. Air preheated to a temperature above the self-ignition temperature of carbon monoxide may also be supplied.
