Nickel 200 bars are widely used in the chemical and petrochemical industries for their excellent corrosion resistance. But have you ever wondered how they are fabricated? In this blog post, we will take you through the fascinating world of the fabrication techniques behind nickel 200 bars. We will cover the different processes involved in nickel bar production, the properties of nickel 200, and why it’s such a popular choice in industrial applications.
First Step in the Fabrication Process of Nickel 200 Bars
The first step in the fabrication process of nickel 200 bars is melting. Manufacturers typically use electric arc furnaces to melt the raw material. The raw material is usually scrap, which must be meticulously sorted to ensure the right chemical composition. The manufacturer sets the furnace to melt the scrap pieces at a specific temperature and time to obtain the right chemical composition. Once the melting process is complete, the liquid metal is ready to be cooled and solidified.
Second Step
After melting, the next step is to shape the metal into bars. The most common technique used to transform liquid metal into bars is the continuous casting process. In this process, the melted nickel 200 is continuously cast into a mould that shapes it into bars. The molten nickel is poured into a tundish, which feeds the liquid metal into the mould. The mould walls are made of copper to enhance the cooling process, producing a uniform solid structure.
Third Step
A rolling mill creates the desired bar shape after the solidification process. The rolling process compresses the nickel 200 at high pressures, reducing its thickness and improving its mechanical properties. The rollers used in the process apply pressure in a horizontal position, flattening the nickel 200 into a thin sheet. The bar then receives the final finishing touches to ensure a smooth surface.
The Final Step in the Fabrication Process of Nickel 200 Bars
Now we come to the final stage of fabrication: annealing. Annealing is a process where nickel 200 bars are exposed to high temperatures to relieve any stresses generated during the metal’s manufacturing process. The material is heated to specific temperatures and held for a designated period to improve its crystal structure. Annealing also improves the bars’ malleability, making it easier to weld, shape, and form them into various application-specific shapes.
Conclusion:
The fabrication of nickel 200 bars is a complex process that requires a skilled workforce, state-of-the-art equipment and, of course, the right raw materials. The finished product is a reliable and corrosion-resistant bar ideal for industrial applications like chemical processing and power plants. The techniques used to manufacture nickel bars ensure they are versatile, reliable and robust. Understanding the fabrication techniques behind this high-performance nickel superalloy helps us appreciate the science behind materials and the innovation that goes into creating the products we use every day.
