Aug 07, 2016· Description of Sponge Iron Manufacturing Process. Most of the plants in India use DRI process—asolid state direct reductionprocess by whichiron oreis reduced to sponge without phase change. Raw material mix-iron ore, dolomite and coal are fed to one end of rotary Kiln as well as some fine coal also fed from discharge end and product sponge iron along with …
However in the coal/oil-based DR process, thereducing gas is generated from hydrocarbons (primarily coal, but sometimes oil and natural gas) in the reduction zone of the furnace, which is typically a rotary kiln.Typical examples of the coal-based …
DRI production Direct reduction of iron is the removal of oxygen fromiron oreor 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 oreis used mostly in pellet and/or lumpy form
The coal-based processes can be grouped into four categories according to their reduction reactors. Therotary kilnprocesses include ACCAR/OSIL, DRC, Krupp-CODIR and SL/RN processes. Kinglor Metor
Jan 05, 2012· TheCircofer® processis a coal-based direct reduction process developed by Outotec GmbH. Fine ore is pre-reduced to DRI in a CFB (circulating fluidised bed) reactor (Fig. 12.14). Char and hot reducing gas are produced as by-products
Processes thatproduce iron by reductionofiron ore (in solid state) belowthemelting pointare generally classified as DR processes. Based on the types …
Natural gas and coal are the two primary fuels used in DRI production. Whereas more than 90% of the global DRI plants use (lower grade) natural gas, production in India is primarily coal based. The energy consumption in natural gas based DRI production is …
The SLRNcoal-based processuses lump ore and, increasingly, pellets as feedstock. There are variants of these processes which are described on the website of the various technology providers.

processwas a natural gas/air fired rotary-hea rth-based DRI processoriginally developed in 1965 as a joint venture of Midland Ross Corporation, National Steel Corporation and Hanna Mining
TheprocessofCoal based DRIplant is thoroughly studied and a few initiatives were taken to reduce energy consumption of the plant.Innovative development and drives have been taken in this area – and that have enriched the desired results. By adopting the ways and means – energy conservation and carbon emission, both were improved substantially
InDRIproduction India deserves special attention, not only because the country is the larges producer ofDRI, but also because production is primarilycoal based. In indiaDRIplants can be easily erected with the help of local suppliers, and the investment in a 100 t/d capacityDRIplant can be recovered in 12 to 18 months

The above Mekko chart represents an elucidated view of the productionprocess-wise share ofDRIin 5 key countries, including the US, India, China, Saudi Arabia, and Oman. The share of gas-based DRIproductionprocessis higher compared to itscoal-basedcounterpart, particularly in India and Saudi Arabia
By Noah Beecher Kelk Metallurgicalcoal, also called metcoal or cokingcoal, is a type ofcoalthat is used in the production of steel. It is of a higher purity than thermalcoalwhich is used in energy generation. To make steel, metcoal is heated at around 1100 degrees C to remove water and other chemicals. This is done without the presence of oxygen. The result is a lump of near-pure …

Nov 13, 2020· Incoal-based DRI process, accretion formation inside the rotary kiln is a genuine complex problem. Accretion formation in a rotary kiln of 100 tpdDRIplant has been investigated. The nature of accretion formation with respect to the charge burden and operational parameter have been discussed. High ash content in thecoaland excess use of dolomite lead to …
