Keywords: Sponge Iron, Heat Transfer, Rotary Kiln . 1. Introduction . In Rotary kiln, carbon is charged from either end, in one end in the form of coal particles and in another in form of coal lumps. The coal reacts with air to form carbon monoxide which then reduces iron oxide (ore) to iron. So, in a kiln,
In the DRI plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material like coal or lignite. The reduction is carried out in a rotary Kiln (which is inclined and rotates at a pre-determined range of speed) at a …
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 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 ...
In the present study, estimation of actual output parameters is carried out for a sponge iron production process by designing a Multilayer Perceptron model that uses a momentum learning algorithm. For this purpose data of temperature profile of rotary kiln are collected from typical sponge iron plant, which correlate four air inlets and twelve temperatures measured at different lengths of the ...

2. ED, SIMA requested the participants to volunteer to spare their rotary kiln for carrying out the R&D for exploring the use of Syn Gas in the rotary kiln. Mr. T Srinivasa Rao, MD, Balajiswamy Premium Steels Pvt Ltd offered his 50TPD kiln for this purpose. 3. Presentation from Tata Sponge Iron Ltd was very much liked and lot of the people showed
In the Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln (which is inclined and rotates at a pre-determined range of speeds) at a stipulated temperature (850°C -1,500°C).
The Rotary Kiln process is a well-established process for production of coal based DRI Lumps. The process, in general, salient features of the various rotary kiln processes available now for commercial exploitation, and the process selected are discussed in this chapter.
However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron in tunnel kilns.
