<P> Integrated steel plants are large, handle everything in one complex - from putting together raw material to steel making, rolling and shaping . Iron ore, coke, and flux are fed into the blast furnace and heated . The coke reduces the iron oxide in the ore to metallic iron, and the molten mass separates into slag and iron . Some of the iron from the blast furnace is cooled, and marketed as pig iron; the rest flows into basic oxygen furnaces, where it is converted into steel . Iron and steel scrap may be added to both to the blast furnace and to the basic iron furnace . There are about five integrated SAIL plants in India . </P> <P> There are more than 50 iron and steel industries in India .
