The iron and steel industry is one of the most important industries in India. During 2014 through 2015, India was the third largest producer of raw steel and the largest producer of sponge iron in the world. The industry produced 91.46 million tons of total finished steel and 9.7 million tons of pig iron. Most iron and steel in India is produced from iron ore. The Indian Ministry of Steel is concerned with: the coordination and planning of the growth and development of the iron and steel industry in the country, both in the public and private sectors; formulation of policies with respect to production, pricing, distribution, import and export of iron and steel, ferro alloys and refractories; and the development of input industries relating to iron ore, manganese ore, chrome ore and refractories etc., required mainly by the steel industry.
There are two types of steel plants - mini steel plants and integrated steel plants.
Mini steel plants are smaller, have electric furnaces, used steel scrap and sponge iron. They have re-rollers that use steel ingots as well. They produce and introduction.Carbon steel mild and Alloy steel of certain specifications. There are around 650 mini steel plants in India.
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.
