Download PDF …Jan 01, 1999· This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is 'directly reduced' in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently ...اقرأ أكثر
Jan 25, 2020· DRI production with syngas. The gas based direct reduction (DR) process is designed to convert iron pellet/lump into metallic iron by the use of reducing gases in a solid-gas moving bed shaft furnace. O2 is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metallized DRI.Direct Reduced Iron (DRI) Refractory. Direct Reduced Iron (DRI) is an alternative to the blast furnace processes to produce a source of iron units. Greater availability of natural gas has replaced classic coke oven coal-based processes. Several processes are commercially viable today and they use a number of ways to achieve good quality DRI.اقرأ أكثر
