Table 4 | Reduction Efficiency of Iron Ore–Coal Composite

In order to explore the efficacy of iron ore–coal composite pellets over ordinary green pellets, indurated pellets, briquettes as well as standard charging of material in the form of concentric layers of iron ore and coal fines, or their mixture, these pellets were tested at 1,150 °C in a 7 tons per day (7 tpd) pilot tunnel kiln Reduction of iron ore coal composite pellets in tunnel kilnIronmaking in the rotary hearth furnace (RHF) is a direct reduction process which utilizes noncoking coal for the reduction of iron ore The RHF is the process reactor which consists of a flat, refractory hearth rotating inside a stationary, circular tunnel kiln Inside the RHF, direct reduction of iron ore or ironbearing waste materialsIronmaking in Rotary Hearth Furnace – IspatGuruProcess Of Iron Reduction In Tunel Kin And Rotary Kiln Process Of Iron Reduction In Tunel Kin And Rotary Kiln Sponge iron production by tunnel kiln method was developed from 1911 as H246gan228s method in Sweden After many modifications now this process is a sufficient and effective method for sponge iron production The main advantage of tunnel kiln process is the possibility to buildyoutube tunnel kiln sponge iron process
