1.1 BRIEF OVERVIEW OF THE ORGANIZATION

Over View of RINL

1.1.1 Over View: Visakhapatnam Steel Plant (Vizag Steel) is the country’s first shore based integrated steel plant. The company is 100% owned by Government of India. The plant with 3Mt liquid steel capacity with 100 % long product portfolio is the largest long product producer in the country. The project which was conceived in 1971, received significant thrust since 1982 with formation of RINL as a corporate entity. The plant was fully commissioned in 1992.
VSP has been certified for all three system standards i.e. ISO 9001:2000, ISO 14001:2000 and OHSAS 18001:1999 and is the first Indian steel plant certified with “Capability Maturity Model Integrated (CMMI) - Level 3 certification for its implementation of …show more content…

It is a complex metallurgical process in which liquid steel is cooled and shaped into semi-manufactures of desired dimensions. To achieve proper quality of cast steel, it is essential to control the metal flow and heat transfer during the casting process. In the continuous casting process, molten steel flows from a ladle, through a Tundish into the mould. It should be protected from exposure to air by a slag cover over each vessel and by ceramic nozzles between vessels. Once in the mould, the molten steel freezes against the water-cooled copper mould walls to form a solid shell. Drive rolls, lower in the machine continuously; withdraw the shell from the mould at a rate or “casting speed” that matches the flow of incoming metal, so the process ideally runs in steady state. Below mould exit, the solidifying steel shell acts as a container to support the remaining liquid. Rolls support the steel to minimize bulging due to the Ferro-static pressure. Water and air mist sprays cool the surface of the strand between rolls to maintain its surface temperature until the molten core is
