    ABSTRACT

    Main purpose of the project report is to study and analysis the behavior of the

    synchronous motors which are used in sinter plant. In sinter plant, the sinter mix is

    converted into blocks (60mm) require for the blast furnace.

    5.6 MW synchronous motors are used to maintain constant vaccum under the

    sinter machine (furnace). These motors are operating at 5.6 MW and 11KV and also at

    different range power factors

    INTRODUCTION TO VSP:

    Visakhapatnam Steel Plant is a symbol of the technical corporation

    between India and Russia. Some of the technological highlights of Visakhapatnam

    Steel Plant are:

    Visakhapatnam Steel Plant is the only shore based integrated steel plant

    in our country. The decision to set up an integrated steel plant at Visakhapatnam by

    the Government of India was taken in the Parliament on 17th April, 1970 and on 20th

    January, 1971, the then Prime Minister, and Smt. Indira Gandhi laid the foundation

    stone fulfilling the long cherished dream of the people of Andhra Pradesh. Theconstruction of VSP is taken up by steel authority of India (SAIL). With economic

    and Technical Corporation of rest while Union of Soviet Socialist Republics.

    Visakhapatnam is a fast growing city and a railway junction station in

    the Eastern Ghats and the coast of Bay of Bengal. It is the district headquarters.

    Visakhapatnam is the home for several heavy industries in the Public Sector like

    BHPV, Hindustan Zinc, Hindustan Shipyard, HPCL etc. It also houses establishmentslike NSTL, Eastern Naval Command, NAD, Visakhapatnam Port Trust, and Centre

    for naval architecture etc. Visakhapatnam Steel Plant is located 15 Kms to the South

    West of the Visakhapatnam Port. It lies between the Northern boundary of the

    National Highway No. 5 from Madras to Kolkata and 7 Kms to the South West of

    Howrah Madras railway line.

    1.1. Coke Oven and Coke Chemicals Plants:

    Coke oven plant consists of three coke oven batteries of 67 ovens each

    with useful coke chamber volume of 41.6 cubic meters. Each battery is of 7 meters

    height. It produces coke in the sizes of 25 to 70 mm which meet the coke requirement

    of the Blast Furnaces. The annual capacity of the three batteries is 2.261 mt. During

    production operation the CO gas (carbon monoxide) generated is used in the Coke

    chemical plants to extract different Bi-products like Benzyl, Ammonium Sulphate,Tar products etc. After extracting all the valuable products the remaining gas is used

    as energy source.

    1.2 Blast Furnace (BF):

    There two Blast Furnaces named "GODAVARI" and "KRISHNA", each

    of 3200 cubic meter useful volume. Here hot metal is produced from the raw

    materials like iron ore (Lump), sinter, coke and limestone etc. The annual capacity of

    this facility is 3.4 mt. From molten hot metal pig iron / steel is produced.

    1.3 Steel Melting Shop:

    10/59

    There are three nos. of LD converters each of 133 cubic meters with a

    capacity to produce 3 mts of liquid steel. The production capacity of a plant is its

    capacity to produce liquid steel. VSP is a 3 mt plant. SMS also has six numbers of

    four strands continuous casting machines to produce blooms. 2.82 mt of blooms can be cast annually. In this shop hot metal from BF is received in the mixer, kept for

    temporary storage and transferred to converter where charging takes place in presence

    of 99.5% pure oxygen. After Argon rinsing the molten steel is moved from here to the

    six strand continuous casting machines. Blooms are formed which form the input

    material for the mills. Blooms are also taken as input to small steel making industries.

    1.4 Rolling Mills :

    There are three rolling mills in VSP.

    Light & Medium merchant mills: It includes the billet mill and bar mill. It

    has a two strand rolling mill. It produces billets, bars and structures. The

    annual capacity is 1.857 mts of billets and 7.1 mts of bars & structures.

    Wire Rod mill: It is a high speed four strand continuous mill. The mill

    is designed to produce wire rods in plain rounds and ribbed bars (5.5 to 12.7

    mm diameter). The annual capacity of wire rods production is 0.8 mt.

    Medium and Merchant mill: This mill produce squares 12 to 65mm,

    flats 30 to 150mm, channels and angles etc. This mill has an annual

    capacity of 0.85 mt of bars and structures.

    1.5 Thermal Power Plant:

    The production capacity is 240 MW from the four turbo generators each

    of 60 Mw capacity. There are nos. of Turbo blowers each having a capacity of 6067

    NM3 / min of cold blast. Power is also generated from BPTS (back pressure turbine

    station) and GETS (gas expansion turbine station) in VSP in small quantities.

    Water needs of the plant are met from the Yeleswaram reservoir

    specially constructed for the plant along with the 150 km long walled canal and the

    Kanithi balancing reservoir in VSP towns. VSP has a large township with all modern

    amenities like hospitals, schools, clubs, function halls, shopping centers, and parks for children, good roads and protected drinking water. The products manufactured by

    VSP are pig iron, steel billets, wire rods.

    SINTER PLANT

    Sintering:Sinter is a hard & porous ferrous material obtained by agglomeration of

    iron Ore fines, coke breeze, lime stone fines, metallurgical wastes viz. flue dust, mill

    scale, Ld slag etc. sinter is a better feed material to Blast Furnace in comparison to ore

    lumps and its usage in Blast furnace help in increasing productivity, decreasing the coke

    rate & improving the quality of hot metal produced. Hot sinter discharged from

    sintering machine is crushed to 25 mm- 50 mm size and cooled before dispatching to

    Blast Furnaces .

    The dust laden air from the machines are cleaned in scrubbers & electrostatic

    precipitators to reduce the dust content to 100 mg/ level before allowing to escape into

    the atmosphere and thus helping in maintain
