Sponge iron kiln’s cylinder: The design of the sponge iron rotary kiln cylinder is more reasonable. The cylinder is rolled with a Q235-B steel plate to ensure five mechanical properties, usually with automatic welding. The wall thickness of the cylinder is generally 25 mm, and that of the firing zone is 32 mm

Rotary Kiln with SL/RN Process. Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, and 500 TPD) Solid-state reduction of Iron Ore using either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI). Since DRI is produced by removing oxygen from iron ore, its structure is just like a sponge with a network of …

Looking forward to the need of developing coal-based sponge iron technology in India, a country having no significant resources of either coking coal or natural gas, the Research and Development Division of the Tata Iron and Steel Company Limited (TISCO) set up a rotary kiln based direct reduction pilot plant in 1975. In this pilot plant, a totally indigenous technology for production of

energy survey of the coal based sponge iron industry

Sep 01, 2015 · In the sponge iron process concentrated and finely divided iron ore is reduced in solid phase into sponge iron at high temperatures in rotary kiln. The process is very energy demanding. In order to identify the largest losses and to find ways to increase the efficiency, an energy survey of the sponge iron plant was carried out for a number of different production rates

MAGMA produces pig iron from iron ore, by the method of liquid-phase reduction of iron. In the process, iron ore fines & limestone are pre-heated by the off-gases of the smelting chamber in a rotary kiln, to temperatures of 900-1,000°C & then hot-charged into the MAGMA chamber. Coal is directly burnt in oxygen inside MAGMA
