Blast furnace simulation laboratory reduction for simulated PCR based on measurements in the EBF showed that larger pores were observed in the Fe met pellet periphery at high PCR. At simulated low PCR the Fe

اقرأ أكثرProcess. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
اقرأ أكثرReduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of 800 to 1,200 °C in the presence of the reducing gas syngas, a mixture of hydrogen and carbon monoxide. DRI, direct reduced iron, is produced through the removal (reduction) of oxygen from iron ore in its solid-state.
