The main raw materials for the production of DRI by the rotary kiln process are (i) sized graded iron ore or iron ore pellets, (ii) non-coking coal, and (iii) dolomite in small quantities to scavenge the …
SIMA PRODUCTION OF SPONGE IRON THROUGH TUNNEL KILN PROCESS SS. Bedarkar Electrotherm (India) Limited Direct reduction includes the processes in which iron 'ore (lumps/ pellets) is reduced in the solid state and oxygen is removed by either solid or gaseous reducing agents. The reductants used are non- coking coal or natural gas.
In India the process is mainly coal based, and the plants' payback times are around 1.5 years. ... (RHF) that is a flat, refractory-lined hearth rotating inside a high-temperature circular tunnel kiln (Huitu et al ... DRI production is destined to increase in the next and far future. This is due to the continuous innovations of the plants ...
Type DRI The Non-conventional Method of making Sponge Iron is done in the Tunnel Kiln Process as compared to the Old Rotary Kiln process. In the conventional process of Tunnel Kiln Process, the Iron Ore and Coal are fed in the Crucibles or Saggars of Silicon Carbide and Loaded on the Trolleys.
DRI or sponge iron is a high-quality metallic product and used as a feed-stock in the induction furnace / electric arc furnace. The investments on the tunnel kiln plants are 20-25% lower than the Indian rotary kiln plants. The cost of production is also 20-25% lower.
A diverse technology portfolio emerges in India to tackle an array of challenges. India's existing production fleet can be characterised as relatively young, energy-intensive and growing at a faster pace than …
DRI production 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 …

DRI as well as accretion formation depend on hold-up time of charged material in the kiln, which is decided by rotation of kiln. In the present case, rotation of the kiln was maintained around 0.5 rpm. The maximum output from the kiln per day was 70% and during the accretion formation as low as 36%.
India is now the world's largest producer of DRI. Currently, there are two primary means of DRI production in India: small-scale rotary kilns using coal and iron ore lump, and largelocal scale shaft furnace plants using - natural gas and iron oxide pellets and lump.

The greatest increases in DRI production were seen in Iran, India and the United States, which combined produced three million tons more than in 2015. The United Arab Emirates, ... India is produced in rotary kilns which employ coal as the reduc-tant and fuel. For this reason, Iran is the number one producer of gas-based DRI.
DRI production in India. India produced 22Mt DRI in 2011, a drop of 1.45Mt (7%) from 2010 but the country still remains the world's largest producer by a wide margin. India's drop in production was a result of several economic factors. First, there was a slowing of the general economic growth that has been developing for years.
Of the total DRI production in 2008, 74% was produced from coal in rotary kilns and 26% from natural gas in shaft fur-naces. India is now the world's largest producer of DRI. Currently, there are two primary means of DRI production in India: small-scale rotary kilns using local coal and iron ore lump, and large-scale shaft furnace plants ...
India is the world's largest producer of Direct Reduced Iron (DRI) or Sponge Iron. During 2017-18, total production of sponge iron is reported at around 30.511 million tonnes of which 85% are coal based plants and 15% are gas based plants. Post-liberalization, technological profile of the Indian Steel Industry has undergone substantial change.
Global crude steel production capacity has more than doubled over the past two decades; three-quarters of the growth took place in China and around 85% of total capacity today is located in emerging economies.
