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

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
Despite the negative encounters of Andrew Carnegie’s Steel Company, the exploration and exchange of Carnegie Steel is that the steel was cheap. This had a positive impact on the United States because steel fed national growth, steel meant more jobs, national prestige, and a higher quality of life for
After the Bhopal Disaster, Union Carbide made an ethical decision through their legal strategy to secure the best outcome for themselves and to keep their company from going bankrupt multiple times over. Union Carbide used the corruption of the Indian court system to their advantage to minimize the amount they would pay in damages to the victims. Their strategy wouldn’t be considered moral to the victims of this chemical explosion if the trial were kept in the American court system. What is ethical isn’t always considered moral to all the parties involved. With a company facing bankruptcy and losing everything they had, the only ethical decision was to use the court systems to their advantage. By doing so, they made the ethical decision strictly
3.12 Rolling: A producing method that forms threads on screw shafts by mistreatment pressure. Rotating dies containing desired thread profile are ironed against a blank shaft to displace material and make thread forms.

The Bethlehem Steel was the was second largest steel company in the United States during its booming years. They made steel that built the Golden State bridge, skyscrapers in New York and tanks and war equipment for WW2. It seemed like the Bethlehem steel would never close, but like every good thing it had to come to an end. One major reason the steel was shut down was because they didn’t advance their equipment and unlike the Bethlehem Steel, foreign steel companies upgraded their equipment with mini mills which allowed them to produce steel cheaper and at a quicker rate. The Bethlehem Steel should have changed certains things, but since they had to close there is one thing I’d preserve about the the Bethlehem steel is their large blast furnaces.
I hereby attest that I have read --- pages of my novel. The entire novel is ---- pages in length. On my honor as a Chaminade gentleman and a young man of integrity, this statement is true.
This product is manufactured by chemically applying a conversion layer on Zincalume steel to enhance coating adhesion. Subsequently a specially formulated primer is baked on surface. And finally a durable exterior grade top-coat is baked on. 10 - 12 years warranty is also standard on this material.
Metal stamping machines are utilized to give the careful shape and parameters to the metal items. At the point when a metal sheet is embedded into the metal stamping machine, it can be formed into the definite shape. The sort of shape that must be given to the item ought to be pre-decided before putting the metal in the stamping machines. The client gives an example or a chart of the item that must be made. Now and again, the client may not realize what the last item will resemble. He will accompany an unclear thought of what reason the item would serve. Most metal stamping makers have outlining abilities to help the client with what the real plan and necessities of the item ought to be.
Is it a big change to support what's going to happen to steel industry in the future?
The companies I have selected for this assignment is Malaysia Steel Works (KL) Bhd (5098) and Kossan Rubber Industries Bhd. (7153), both of the company is from industrial products sector and its share is traded in main market.

Maraging steels of different compositions have been prepared by means of induction furnace electro slag remelting technique using titanium and chromium instead of cobalt which is a high expensive strategic element, also nickel content was reduced to 10-13%. Mass attenuation coefficients, half value layers and effective atomic numbers have been determined for the prepared samples at photon energies 238, 583, 661, 911, 1173, 1332 and 2614keV. The results are compared with the corresponding theoretical calculations. In addition, the hardness has been determined for the investigated steels. High nitrogen free nickel steel and carbon steel samples have been also investigated for the sake of comparison. The achieved results reveal the superiority of cobalt-free maraging steels comparing with the other investigated high nitrogen free nickel and carbon steels to be used as a proper shielding material in the nuclear domain. Among the investigated cobalt-free maraging steels, a steel of constituent's "0.05%C-13.26%Ni-2.15%Cr-4.3%Mo-0.02%Ti-0.01%V" has the best attenuation properties. The obtained results are useful for potential applications of these alloys in industrial and nuclear applications.
The group is also one of the largest manufacturers of small and medium sized steel forgings and the second largest forgings manufacturer in India.
