commissioned in 1991 the raigarh plant has a manufacturing capacity of 1.37 mtpa and metallic iron content of more than 81%. the plant uses direct reduced iron (dri) process method of production and utilises ten indigenously developed rotary kilns (6 kilns of 300 tonnes per day and 4 kilns of 500 tonnes per day).
the sponge iron is a substitute for scrap in the electric arc furnace which can be easily manufactured from indigenously available raw materials at very competitive price. it is the iron ore reduced in solid state by a direct reduction process using natural gas or non cooking coal as reluctant. the sponge iron is also known as direct reduced
sponge iron plant manufacturers the process was widely accepted by almost all developing countries where generation of scrap was less in comparison to requirements. steel produced by recycling process found much cheaper than the steel produced by blast furnace process.
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 stipulated temperature ( 850 °c – 1050°c).
major plant facilities 1-material preparation system - raw material system mainly consist vibro feeder crusher and screen. iron ore crushing is not required since sized material has to be purchased. iron ore of size 5 mm to 20 mm is being used for the production of sponge iron. iron ore is being fed to the ground
some cocktails call for crushed ice rather than ice cubes. crushed ice melts quicker and makes more of a slushy drink—perfect for summer coolers. chow's amy
