摘要： In a method of producing iron and steel, from iron ores largely composed of iron oxides, wherein a direct reduction process is used to produce a solid particulate intermediate product, generally known as sponge iron or Direct Reduced Iron (DRI); pneumatically conveying the DRI in a closed pipe from the reduction reactor of the direct reduction process to the metallurgical furnaces where liquid iron or steel are produced, for example electric arc furnaces, induction furnaces, basic oxygen furnaces, etc. or to a briquetting press to form DRI briquettes, or simply to a silo or storage bin, or in general to a subsequent processing step for said DRI. When the carrier gas is recirculated for reuse, surprisingly air is preferred as the source of such gas, especially for reactive hot DRI. This method has a superior efficiency and productivity and reduces the overall energy consumption relative to currently used DRI steelmaking plants. This is also applicable to pneumatic delivery of cold (or hot) ore to the reduction reactor.

摘要： In method and apparatus for producing iron and steel from iron cores largely composed of iron oxides, wherein a direct reduction process is used to produce a solid particulate intermediate product, generally known as sponge Iron or Direct Reduced Iron (DRI); pneumatically conveying large iron-bearing particles, such as pelletized iron ore or particularly DRI, in a closed transport pipe, eg. from the reduction reactor of the direct reduction process to the metallurgical furnaces where liquid iron or steel are produced, for example electric arc furnaces, induction furnaces, basic oxygen furnaces, etc. or to a briquetting press to form DRI briquettes, or simply to a silo or storage bin, or in general to a subsequent processing step for said DRI. When the carrier gas is recirculated for reuse, surprisingly air can be a preferred source of such gas, especially for reactive hot DRI. This method has a superior efficiency and productivity and reduces the overall energy consumption relative to currently used DRI steelmaking plants.By using pneumatic conveyors, elements of the plant may be arranged side by side rather than one on top of the other, whereby the overall height of the plant may be reduced.

摘要： A container to handle particulate solids comprising a downwardly converging wall extending from an inlet to an outlet, the wall being provided with an internal inverted step extending along a portion of the converging wall. In order to minimize the solids compaction and flow stoppages, the internal inverted step extends helically along at least a portion of the converging wall to provide a continuous increase in the cross-sectional area of the container to promote solids flow.
摘要翻译：一种用于处理颗粒固体的容器，包括从入口延伸到出口的向下会聚的壁，所述壁设置有沿着会聚壁的一部分延伸的内部倒置台阶。为了最小化固体压实和流动停止，内部倒置步骤沿着会聚壁的至少一部分螺旋地延伸，以提供容器的横截面积的连续增加以促进固体流动。
