evident from the steep rise in world DRI production during the past three decades. India, entered the sponge iron industry only in 1980, when the coal based DRI plant of Sponge Iron India Limited (SIIL) was commissioned at Kothagudem, in Andhra Pradesh. 2. The reasons for the tremendous growth of the sponge iron industry

The direct carbon dioxide (CO 2) emissions from the iron and steel sector are nearly 7 % of the global CO 2 emissions from energy use. India is the world's second-largest producer of steel and the largest sponge iron producer. India produces one-third of the global sponge iron, mostly from rotary kilns using coal as an energy source, resulting in higher …

that the working plants are 360 and sponge iron production in the country stood at 20 million tonnes in 2008-092. This implies a capacity utilisation of a mere 55 per cent for coal based plants and of about 90 per cent for the gas based ones. Ministry of Steel quoted a figure of 353 sponge iron plants in India with a capacity of 25 MTPA in a

The metallic iron in this process is produced by the reduction of iron oxide below the fusion temperature of iron ore (1535 deg C) by utilizing carbonaceous material present in the non-coking coal. As the iron ore is in …

The development and research of smelting reduction has gone through three generations. The first-generation process began in the 1920s, in which the main research was the one-step method of using concentrate and coal in one reactor, such as the reduction of iron ore with carbon and oxygen in converter proposed by Hoesch Iron and Steel Company of …
