✦ Synopsis

With emphasis on modernized operation and increased efficiency, the reconstruction of two older blast furnaces with a working volume of 1323 and 1756 m3, at the Durgapur Metallurgy Complex in India, was evaluated. A coke efficiency of 520 kg C/ton of pig iron was displayed by the modernized blast furnaces and a further decrease was feasible despite the use of high-ash coke and AIz03-containing slag. The pig iron productivity was projected at 1.3-1.4 ton/m3/24 h, with 0.025% level of sulfur impurity.
