Abstract: There is described a mill for the production of steel from liquid and solid charging substances. It includes a coking plant, a blast furnace plant, a converter steelworks, and a plant for the direct reduction of iron ore. The converter steelworks is charged with molten pig iron from the blast furnace and with scrap as well as with sponge iron from the direct reduction plant. The reduction gas is composed of converter offgas, top gas and blast furnace gas. In order to avoid coal deposits in the direct reduction plant and to improve the composition of the reduction gas, the coke oven gas component is subjected to fractionation by alternating pressure adsorption so as to increase its portion of hydrogen and to lower its portion of hydrocarbons.

Abstract translation: 描述了一种用于从液体和固体带电物质生产钢的研磨机。 它包括炼焦厂，高炉厂，转炉炼钢厂和直接还原铁矿石的工厂。 转炉钢铁厂从高炉和废钢以及来自直接还原厂的海绵铁装入熔融生铁。 还原气由转炉废气，顶气和高炉煤气组成。 为了避免直接还原装置中的煤沉积并且改善还原气体的组成，通过交替的压力吸附对焦炉气体组分进行分馏，以增加其部分氢并降低其部分烃。
