摘要： A direct reduction process producing DRI from iron oxide particles by reduction at a about 750° C. with a reducing gas mainly H2 and CO, that also includes CO2, H20, and methane, a the reduction reactor and the top gas effluent from the reduction reaction after cooling/scrubbing is split. The resulting first top gas portion with a first hydrocarbon-containing make-up gas passes through a catalytic reformer yielding an improved hot reducing gas first effluent. The second top gas portion passes through a CO2 removal unit and then with the second hydrocarbon-containing make-up gas passes through a heater yielding a hot CO2-lean recycle reducing gas second effluent. The first and second effluents are fed to the reducing zone of the reduction reactor as the reducing gas reactant. The flow rate of at least the second of the two make-up gases is regulated to control the carbon content of the DRI produced.

摘要： A carbonaceous-based metallizing method and apparatus wherein a metallic oxide is converted into a carbon-containing, metallized intermediate that is melted in an induction channel furnace to produce liquid metal from said metallic oxide. In the application of iron ore in the form of fines or concentrate, using low-cost coal will greatly reduce capital and operating costs by virtue of eliminating agglomeration of ore, cokemaking, and blast furnace operation. The liquid iron so produced is efficiently converted into steel in a steelmaking furnace such as a basic oxygen furnace (BOF), especially when it is physically integrated to the induction channel furnace wherein the liquid iron is directly poured into the integrated BOF by the induction channel furnace, producing low-cost steel, little heat loss, and minimum emissions.
摘要翻译：一种碳质金属化金属化方法和设备，其中金属氧化物被转化为含碳的金属化中间体，该金属化中间体在感应通道炉中熔化以由所述金属氧化物产生液体金属。在细粉或精矿形式的铁矿石应用中，通过消除矿石结块，炼焦和高炉操作，使用低成本煤炭将大大降低资金和运营成本。如此生产的铁水在碱性氧气炉（BOF）等炼钢炉中被有效地转化为钢，特别是当其物理地集成到感应通道炉时，其中铁水通过感应通道直接注入整合的BOF 生产低成本钢材，热损失小，排放量低。
