摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译： 通过将锰或氧化硅颗粒与碳质材料（例如焦炭）颗粒混合，在固态反应中形成锰或碳化硅。 这些材料可以形成包括过量含碳材料的附聚物，并在合适的反应器容器中加热。 还可以加入铁源，例如生铁和/或废铁。 在这种情况下，锰或碳化硅溶解在铁水中以产生硅铁或铁锰合金。
