Direct reduced iron process tecscience
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 socalled 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.

Cold Bonding of Iron Ore Concentrate Pellets: Mineral
Jan 28, 2014· Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and gratekiln furnaces. However, heat induration requires tremendous quantities of energy to produce highquality pellets, and is consequently expensive. Cold bonding is a lowtemperature alternative to heat induration. Pellets can be cold bonded using lime, cement, sponge iron powder, .
