Jamshedpur, India (Usha Alloys & Steel Division)

Usha Martin’s integrated steel plant near Jamshedpur has one million tonne capacity and is one of the India’s largest speciality steel plant in long product segment. The Steel Plant was set in 1974 in iron ore and coal rich belt of India . It has the distinction of being India’s first steel plant to receive the TPM Excellence Award from JIPM, Japan. steel-plant-pocess-flow

The steel plant was the first steel plant in India to use Hot Metal in Electric Arc Furnace, that has become an industry wide practice now.

The steel making route is Blast Furnace & DRI Kiln, Electric Arc Furnace, Ladle Refining Furnace, Vacuum Degassing, and Continuous Casting Machines supported by in-house ore beneficiation, Sinter, Coke-oven, Pellet, DRI, Power Plant, and Lime kilns.

The steel plant is located in Jharkhand, a state rich in Iron ore and Coal reserves. For feeding the Steel Plant, the company has captive iron ore mines and coal mines located in nearby area within the state. The iron ore is used to make Hot metal from Blast Furnace through Sinter, and Sponge Iron through pellets and DRI kilns.

The hot metal and sponge iron is charged in Electric Arc Furnace for making steel, which further is refined in Ladle Furnace and Vacuum Degassing Units. We have 2 Blast Furnaces having capacity of 245 cubic metre and 380 cubic metre and 3 Electric Arc Furnaces having capacity of 40 MT (2 Nos) and 70 MT (1 No). The state of the art Continuous Casting Machines produce billets & blooms in sizes 300 x 360 mm, 200 x 240 mm, 200 x 200 mm 150 x 150 mm, and 130 x 130 mm.

The Rolling facilities include Wire Rod mill and Bar rolling mills where the rolled products in the form of 5.5 mm to 180 mm dia, and Round Cornered Square (RCS) from 63 mm to 200 mm size.

The plant has an illustrious history of collaboration with well known companies like Ovako Steel (now SKF Steel) of Finland, Nikko Industries of Japan, Hamburger Stahlwerke GmbH of Germany, Daido Steel of Japan and recently Aichi Steel Corporation (a Toyota Group Company) of Japan. The high quality steel has provided Usha Martin a strong presence in automobile industry.

Currently, the company caters to Automotive Sector, Heavy Earth Moving Equipments, Tractors, Aluminium Industry, and Oil & Gas Sector. Some of the components for which we supply steel are crank shaft, connecting rod, transmission gears, crown wheel & pinion, front axle beams, rear axle shaft  steering knucle, hubs(front/rear), spindle & spring steel flats in automotive sectors , cathode and anode bars for aluminium industry, flanges, gear and shafts  for oil & gas sector, and piston rods & pins for heavy earth moving equipments.

Approvals from prominent companies like Tata Motors, Caterpillar, Graziano, Arvin Meritor, Mahindra Forging, Bharat Forge, John Deere, Dana Corporation etc is a result of the high quality steel produced by Usha Martin.
