Steel has always been the backbone of nation’s economy. From an annual production of 13million ton in 1900, global steel production raised to 300 million ton in 1950 and to 842 million ton in 2000. India produces 30 million ton per annum from 9 major plants. The major steel plants contribute 19 million tones and the rest is contributed by secondary sector. Visakhapatnam Steel Plant is one of the 6 integrated steel plants contributing 6.3 million ton of liquid steel per annum. It is the only steel plant in India accredited with ISO 9001, ISO 14001and OHSAS 18001 certificates for Quality environment and Safety aspects of the steel making activities. A Roll neck sleeve is the rotating element of the bearing assembly in a rolling mill. It features a precision finish obtained by grinding both inside and outside with utmost precision being ensured for the outside diameter finish. The sleeve bore is tapered section, an end section aligned axially with the internally tapered section, and a cylindrical outer surface surroundings the internally tapered section. The roll neck sleeve outer surface is adapted to be rotatably journalled in a bushing component of the bearing. The Keyways are placed at the outside of the internally tapered section and exclusively in the end section to serve to rotatably fix the sleeve to the roll neck. This Roll neck sleeves and bushes are get failures because of the reasons a Corrosion on the raceway is generated due to the clearance between the roll neck and the sleeve, insufficient grease or oil between the inner ring bore surface and the roll neck surface (When creep occurs between the inner ring and the roll neck, because of loose fit of them), Wear, Dislocation, Inappropriate handling, Cracks on the inner bore. The main objective of this project is to reduce the inventory cost by reconditioning of sleeves in wire rod mill. In this research work, the damaged sleeves are reconditioned by using Arc welding method. SA 80 E is used as a electrode for arc welding. The welded sleeves are machined on lathe for getting the required size.
