    • The specification discloses a process for heating solid particulate materials. The process comprises entraining the solid particulate materials in a gas to form a stream of gas containing entrained particles and contacting this stream with a stream of hot gases. The contact between the two streams is performed in such a manner that at least a portion of the solid particulate material is heated rapidly and the heated and unheated particles enter flow patterns in which contact between the particles and with interior surfaces of a contact chamber is minimized. A heating and treatment chamber for applying the process to the treatment of solid particulate materials is disclosed. The specification also discloses a molten bath reactor combined with the chamber for heating and treating solid particulate materials. Hot off gases from the molten bath reactor can be passed through the chamber and treated particulate material from the chamber can be inserted in the molten bath reactor or partially recycled through the chamber.
    • 该说明书公开了一种用于加热固体颗粒材料的方法。 该方法包括将固体颗粒材料夹带在气体中以形成含有夹带颗粒的气流并将该流与热气流接触。 两个流之间的接触以这样的方式进行,使得固体颗粒材料的至少一部分被快速加热并且加热和未加热的颗粒进入其中颗粒之间的接触和接触室的内表面之间的接触最小化的流动模式 。 公开了一种用于将该方法应用于处理固体颗粒材料的加热和处理室。 本说明书还公开了一种与室结合的用于加热和处理固体颗粒材料的熔池反应器。 来自熔浴反应器的热气体可以通过室,并且来自室的经处理的颗粒材料可以插入熔池反应器中或部分地通过室再循环。

    • The specification discloses a process for producing a ferroalloy in a smelting vessel. A material containing an alloying metal is injected into a molten bath contained in the vessel. A flux, a carbonaceous material and an oxygen-containing gas are also injected into the vessel. A gas which may be the oxygen-containing gas is injected into the molten bath in order to stir it. The rates of injection of the various components are controlled to achieve control of the oxidising and reducing environment within the vessel consistent with a rapide rate of injection. The material containing the alloying metal is either reduced and incorporated into the metal phase or oxidised and incorporated into the slag. Combustion gases above the molten bath are oxidised to provide further heat to the process. Alloyed metal or slag containing the alloying metal are recovered as product. The process is applicable to the production of ferroalloys such as ferrochromium, ferromanganese, ferronickel and ferrovanadium.
    • 本说明书公开了一种在熔炼容器中制造铁合金的方法。 将含有合金金属的材料注入包含在容器中的熔融浴中。 助熔剂,含碳材料和含氧气体也被注入到容器中。 将可能是含氧气体的气体注入熔融浴中以搅拌它。 控制各种组分的注射速率以实现与注射速率相一致的容器内的氧化和还原环境的控制。 含有合金金属的材料被还原并掺入金属相中或被氧化并掺入炉渣中。 在熔池之上的燃烧气体被氧化以向该过程提供进一步的热量。 作为产品回收含有合金金属的合金金属或渣。 该方法适用于铬铁,铁锰,铁镍铁和铁钒等铁合金的生产。
