SAIL traces its origin to the formative years of an emerging nation - India. After independence the builders of modern India worked with a vision - to lay the infrastructure for rapid industrialisaton of the country. The steel sector was to propel the economic growth. Hindustan Steel Private Limited was set up on January 19, 1954. Hindustan Steel (HSL) was initially designed to manage only one plant that was coming up at Rourkela. For Bhilai and Durgapur Steel Plants, the preliminary work was done by the Iron and Steel Ministry. From April 1957, the supervision and control of these two steel plants were also transferred to Hindustan Steel. The registered office was originally in New Delhi. It moved to Calcutta in July 1956, and ultimately to Ranchi in December 1959.
The 1 MT phases of Bhilai and Rourkela Steel Plants were completed by the end of December 1961. The 1 MT phase of Durgapur Steel Plant was completed in January 1962 after commissioning of the Wheel and Axle plant. The crude steel production of HSL went up from .158 MT (1959-60) to 1.6 MT. A new steel company, Bokaro Steel Limited, was incorporated in January 1964 to construct and operate the steel plant at Bokaro.The second phase of Bhilai Steel Plant was completed in September 1967 after commissioning of the Wire Rod Mill. The last unit of the 1.8 MT phase of Rourkela - the Tandem Mill - was commissioned in February 1968, and the 1.6 MT stage of Durgapur Steel Plant was completed in August 1969 after commissioning of the Furnace in SMS. Thus, with the completion of the 2.5 MT stage at Bhilai, 1.8 MT at Rourkela and 1.6 MT at Durgapur, the total crude steel production capacity of HSL was raised to 3.7 MT in 1968-69 and subsequently to 4MT in 1972-73. Mr. Chandra Shekhar Verma took charge of the office of Chairman, SAIL on 11 June 2010.
Unit profile of D.S.P:
Durgapur Steel Plant is the third integrated steel plant of the then Hindustan Steels Limited to come up under Public Sector in India. Durgapur was selected as location of the plant, for its proximity to coal-fields, the Grand Trunk Road (NH-2), Kolkata - Delhi main railway track, Kolkata port, and power from Damodar Valley Corporation and water from Durgapur Barrage on river Damodar. The plant was set up with an initial capacity of 1 million tonnes per annum of crude steel by a group of British companies in the late 50’s. It was later expanded to 1.6 MTPA in late sixties. Later on, SAIL decided to modernize DSP with government approval in 1989 and the present capacity is 1.8 MTPA of crude steel. What follows is a brief description of all the major production departments of DSP as well as of some important Services departments. RMHP (RAW MATERIALS HANDLING PLANT)
Raw Material Handling Plant is the starting point of steel making process. The objective of RMHP is to receive, unload, stack and supply all the raw materials required for steel making i.e. Iron ore, Limestone, and Dolomite. Apart from this, RMHP also deals with Sinter mix preparation using state of the art automation system. Main functions of RMHP:
1. Tippling of wagons.
2. Stacking and reclaiming of raw materials.
3. Crushing of flux and coke.
4. Sinter-mix preparation and supply to Sinter Plant
5. Iron ore lump screening.
6. Screened iron ore supply to Blast Furnace.
7. High grade limestone, dolomite & iron ore lump supply to BF.
COCC (COKE OVENS & COAL CHEMICALS)
Coke Ovens is an important department in an integrated steel plant. The main objective of this department is to produce coke by carbonization of coal. Coke is an essential raw material for production of Hot Metal. During the process of carbonization of coal, a number of valuable chemicals are obtained. This department also deals with the recovery and processing of these chemicals.
Sintering is the process of agglomeration of fines by incipient fusion caused by heat available from...
