All the important details of dri rotary kiln of sponge iron

Update date: Aug 30

Sep 10, 2020 In the newly designed sponge iron rotary kiln system, a coarse coal branch pipe and fine coal branch pipe are added at the kiln head. The original way of adding 100% coal at the kiln head is changed to 50-70% coal is added together with fine iron ore and dolomite through the mixing mode at the kiln tail, and the remaining 30-50% coal is added

    sponge iron making was in 1972 presumably using a rotary kiln. More than 100 DR processes have been invented and operated since 1920. Most of these have died down but some of them have re-emerged in slightly different form. 6 Sponge iron is mainly produced from iron ore by two different routes (a) - by reducing gases (CO and H 2The basis of the direct reduction process is that solid sponge

    DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H

    The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted Iron (HBI) and Cold Briquetted Iron (CBI); also Low Reduced Iron (LRI), which is pre
