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.
