The production process of Inconel strips involves several steps:
Melting: The process begins with melting the raw materials, primarily nickel, chromium, and other alloying elements, in an electric arc furnace or a vacuum induction furnace. The precise composition of the alloy is carefully controlled to ensure the desired properties of the final product.
Casting: Once the alloy is molten and properly mixed, it is cast into ingots or billets of the desired size and shape. This casting process can be done using various methods such as continuous casting or traditional ingot casting.
Hot Rolling: The cast ingots are then heated to high temperatures and passed through a series of rolling mills to reduce their thickness and form them into long strips. This hot rolling process is typically repeated multiple times to achieve the desired thickness and mechanical properties.
Annealing: After hot rolling, the strips are annealed by heating them to a specific temperature and then slowly cooling them to relieve internal stresses and improve their ductility and toughness.
Cold Rolling: The annealed strips may undergo further cold rolling to achieve the final desired thickness and surface finish. Cold rolling also enhances the mechanical properties and dimensional accuracy of the strips.
Heat Treatment: Depending on the specific requirements of the application, the strips may undergo additional heat treatment processes such as solution annealing, aging, or stress relieving to further improve their properties.
Surface Treatment: In some cases, the strips may undergo surface treatment processes such as pickling, passivation, or coating to enhance their corrosion resistance or improve their surface finish.
Cutting and Packaging: Finally, the finished strips are cut to the desired length, inspected for quality, and packaged for shipment to customers.
Throughout the production process, quality control measures are implemented to ensure that the Inconel strips meet the required specifications for composition, mechanical properties, and surface finish.
