| Description |
India is the largest producer of sponge iron for last few years. Presently its contribution to world production is more than 25% mainly by rotary kiln coal based
process.In India coal based production of sponge iron is about 76% of its total
production. The present investigation to smelt sponge iron fines in bench scale furnace is
of great significance from industrial point of view. These fines were smelted in 50KVA
submerged arc furnace (SAF) using the fines of petro-coke as reductant and that of lime
stone as flux for the production of steel grade iron. The hot metal so produced was having
low percentage of phosphorus, sulphur and manganese and the silicon content in the hot
metal was found to be comparable with that of hot metal produced by Indian blast
furnaces. The power consumption in 50 KVA sub- merged arc furnace was on much
higher side compared to commercial plant.
