Direct reduced iron process - tec-science

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.
