Mini Blast Furnace
SLRM is operating a 262 m3 (working volume) Blast furnace since 2012. Sinter , calibrated lump ore, limestone, dolomite, quartzite and coke are charged into the MBF from top and hot air is passed from the bottom. Ascending oxygen in the air reacts with the carbon in the coke to form CO which reduces the descending iron oxide to iron. Hot metal at required temperature is collected in the hearth at the bottom of the furnace and is tapped periodically and transferred to steel melting shop (EOF). The annual production capacity is about 2,76,000 tones.
