Direct reduction (DR): Direct reduction involves the production of solid iron from iron ores and a reducing agent (e.g., natural gas). The solid product is called DRI and is mainly applied as feedstock in EAF. The direct reduction process has been commercialized since the 1970s and a variety of processes have been developed. (2)

THE SMART CHOICE TENOVA

Energiron products DRI Direct Reduced Iron DRI is reduced iron pellet and/or lump, which is cooled and discharged at low (ambient) temperatures. The process characteristics allow for independent control of the DRI metallization and carbon levels. Metallization can be adjusted at will, typically around 94% and higher. _ DRI carbon levels can be selected in the range of 1.5 4.0%, most of which

SPONGE IRON PLANT

Non-coking coal is required in sponge iron production, since the coking reaction leads to formation of rings inside the kiln. Practically permissible caking index is 3 maximum for rotary kiln operations. 2) Low ash contents:- High ash leads to under utilization of the kiln volume available for reduction. It also increases the consumption of fixed carbon, since additional energy is consumed in

Talk:HIsarna ironmaking process Wikipedia

The SLRN Process : In 1965 the very first DRI developed was the Outokumpu Process by a consortium including STELCO of Canada, Lurgi, Republic Steel (USA) and National Lead, which caused the process to also be commonly known as SLRN. This process adapted the conventional limestone-to-lime converting kiln into an iron ore and coal fines iron reduction kiln which produced sponge iron which

Coal based Direct Reduction Rotary Kiln Process

The coal based direct reduction rotary kiln process was developed for converting iron ore directly into metallic iron without the melting of the materials. The process has the advantage of low capital expenditure and no requirement of coking coal. The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing

DRI production International Iron Metallics Association

Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form. The stone reactions involved in the direct reduction of iron are the
