Products Description

Pure nickel rod is a metal material with excellent workability, which performs well in processing and forming.

Forgeability: Pure nickel rod has good forgeability, that is, its shape can be changed by forging within a certain temperature range. It can be formed through hot forging, cold forging and other processes. By adjusting parameters such as temperature and strain rate, the shape and size of the pure nickel rod can be controlled. Forgeability allows pure nickel rods to adapt to different processing needs and meet the manufacturing requirements of complex parts.

Machinability: Pure nickel rods also show good machinability during processing. It can be processed through common cutting processing methods such as turning, milling, and drilling to achieve precise control of shape and size. Its lower cutting force and better cutting stability make pure nickel rods widely used in the fields of high-efficiency cutting and precision machining.

Weldability: Pure nickel rods have good weldability and can be connected and assembled by various welding methods. It can be welded with other metal materials, such as argon arc welding, resistance welding, laser welding, etc. Good weldability allows pure nickel rods to be easily connected with other components during the manufacturing and assembly process to achieve the assembly of complex components.

Stability of workability: Pure nickel rods show good stability during processing. Even under high temperature conditions, pure nickel rods can still maintain good processability and are not prone to deformation, cracking or damage. This enables pure nickel rods to have reliable performance in high-temperature processing and forming fields, such as high-temperature mold manufacturing and processing of thermal expansion and contraction compensation parts.

All in all, pure nickel rods are widely used in the manufacturing industry due to their good processability.

Production Process:

Material preparation: Select high-purity nickel raw materials, usually electrolytic nickel, electrolytic powder nickel or other higher-purity nickel materials as starting materials. These raw materials undergo chemical analysis and screening to ensure that their chemical composition and purity meet requirements.

Smelting: Put the selected nickel raw materials into a high-temperature furnace for smelting. During the smelting process, the furnace temperature and atmosphere are controlled to completely melt the nickel raw material and achieve a uniform chemical composition. Through smelting, the nickel liquid obtained has high purity and a certain temperature.

Filtration and purification: Remove impurities and non-metallic inclusions from molten nickel liquid. Impurities are separated through filtration and purification processes, such as filters or centrifugal separators, to improve the purity and quality of pure nickel rods.

Continuous casting: Inject the purified nickel liquid into the continuous casting machine. The continuous casting machine controls the temperature and cooling rate to gradually solidify the nickel liquid and form continuous rod-shaped crystals. In this process, the diameter and length of the rod can be controlled to meet the needs of different applications.

Heat treatment: The nickel rods obtained by continuous casting are heat treated to eliminate internal stress and improve the crystal structure. Common heat treatment methods include annealing and solution treatment. Heat treatment can improve the mechanical properties and grain boundary structure of pure nickel rods to meet the requirements of specific applications.

Surface Treatment: Heat-treated pure nickel rods may require surface treatment to remove oxide layers, contaminants, and roughness to obtain a smooth and clean surface. Surface treatment can use mechanical polishing, pickling, electrolytic polishing and other methods.

Inspection and quality control: A series of quality inspections such as appearance inspection, dimensional inspection, chemical composition analysis, and mechanical performance testing are conducted on the finished pure nickel rods. Ensure that pure nickel rods meet specified standards and quality requirements.
