Direct-Reduced Iron - an overview ScienceDirect Topics

2012-1-5  The RHF process was originally developed as an alternative to gas-based direct reduction, making DRI from iron ore and coal. The process started from the patent of D. Beggs applied by Midland-Ross Corporation in 1965 [144]. This process was known as Heat Fast [145].

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.
