Direct reduced iron process - tec-science

2018-6-21  Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Direct-Reduced Iron - an overview ScienceDirect Topics

2012-1-5  In direct reduction the ore is heated to temperatures below its melting point. Direct energy requirements per net ton of direct reduced iron are in the order of 10,000 MJ. The product is 90 to 95% metallized and hence is suitable as a charge in blast, basic oxygen, and electric arc furnaces.

Indirect Reduction - an overview ScienceDirect Topics

The indirect reduction is more exothermic (releases an extra 290 kJ/g mol) relative to the direct reduction. Consequently, the energy efficiency of a process could be significantly enhanced by utilizing the CO formed by direct reduction for subsequent indirect reduction as accomplished in the iron-making blast furnace.
