Production Process
1. Raw Material Selection: The process begins with the selection of high-purity nickel. The nickel used is often in the form of nickel pellets or powders to ensure the final product's purity.
2. Melting and Casting: The selected nickel is melted in a controlled environment to prevent contamination. After melting, the nickel is cast into slabs or bars, depending on the desired end product's thickness and width.
3. Hot Rolling: The cast nickel slabs or bars undergo hot rolling, where they are heated to a specific temperature and passed through rollers. This process reduces the thickness of the nickel and increases its length.
4. Cold Rolling: After hot rolling, the nickel strip is further thinned through cold rolling. This process occurs at or near room temperature, enhancing the strip's strength and finish.
5. Annealing: The nickel strip is then annealed, a heat treatment process that relieves internal stresses, softens the material, and improves its ductility. Annealing is crucial for achieving the desired mechanical properties.
6. Slitting and Cutting: The annealed nickel strip is slit or cut into specific widths and lengths according to application requirements. Precision machinery ensures uniform and accurate dimensions.
7. Surface Treatment: The surface of the nickel strip may be treated through various processes, such as cleaning, polishing, or coating, to enhance its properties or appearance.
8. Quality Inspection: Finally, the nickel strips undergo thorough quality inspections. This includes testing for purity, thickness, width, and mechanical properties to ensure they meet industry standards and application needs.
