Details of DR processes DRI can be used to allow the steel plant to run at a lower overall raw material cost. While the produced DRI is mainly used as the raw material of electric steelmaking, it is also used as blast furnace feed for energy saving (reduction in Based on the types of reductant used, DR processes can be broadly classified into two groups: (1) coal-based DR process and (2) gas-based DR process. The necessity of greenhouse emissions and energy consumption reduction led, in the rece
