Units of India's Iron and Steel Industry

India's iron and steel industry consists of the following units.
Integrated Steel Plants Steel plants of Bhilai, Rourkela, Durgapur, Bokaro, Burnpur, Visakhapatnam, Salem, Vijaynagar and Bhadravati are integrated steel plants.
Mini-Steel Plants These plants generally use ferrous scrap, pig iron or sponge iron as their raw material.

They work through electric furnaces. While integrated steel plants mainly produce mild steel in bulk quantity, mini-steel plants produce mild steel as well as alloy steel including stainless steel. Crude steel production from this sector during April 1999-January 2000 was 7.09 million tonnes (provisional). Mini-steel plants have short gestation periods and they offer great flexibility in operation.

Re-rolling Units The re-rolling units broadly fall under three categories from the view point of their operations

(i) Billet re-rollers Manufacturing of bars, rods, hoop~ light structurals and special sections.

(ii) Secondary producers Manufacturing of bars, spring steel, rivets, nuts, bolts, steel castings, rods, hoops, wire and wire nails, and light structurals.
(iii) Scrap re-rollers Manufacturing of bars and rods.

These rolling units generally work on small scale, and produce articles which are mostly used for agricultural purposes and ferro-concrete works.

The re-rolling mills are scattered throughout the coun. try, particularly in Rajasthan, Maharashtra, Uttar Pradesh, Madhya Pradesh, Punjab, Tamil Nadu, West Bengal, Andhra Pradesh, Bihar, Jharkhand, Assam and Kerala.

Tool Alloy The alloy steel plant at Durgapur has bee~ established with the help of Japanese consortium for erection of the equipment, while a Canadian firm has
