Copper-nickel-chromium process
Author: Robby
The copper-nickel-chromium process mainly includes several major steps such as forging, hot pressing, heat treatment, machining and surface treatment.
First of all, forging is the first step in copper-nickel-chromium alloy processing. During forging, the alloy is heated to the proper temperature and then pressed into the desired shape using mechanical pressure. This method increases the density and mechanical properties of the alloy without destroying its internal grain structure, thereby increasing strength and toughness.
Next is the hot pressing process. Copper-nickel-chromium alloys have good plasticity at high temperatures, so complex parts can be prepared by the hot pressing process. Hot pressing involves heating the alloy to a certain temperature and then placing it in a mold and forming it under pressure to obtain high-precision parts.
Heat treatment is another important step. Copper-nickel-chromium alloys may be subjected to stress, deformation and changes in grain boundary structure during machining, so heat treatment processes such as annealing, solution treatment and aging treatment are required to improve the mechanical properties and heat resistance of the alloy.
Machining includes a variety of methods such as turning, milling, drilling, grinding, etc., which are used to obtain parts of the required size and surface quality. Suitable cutting processes and tool selection are essential to ensure machining quality and efficiency.
Finally, there is surface preparation. The surface of copper-nickel-chromium alloys usually needs to be polished, sandblasted, electroplated, sprayed, etc. to improve corrosion resistance and decorative properties. These surface treatment processes can improve the appearance of the alloy, reduce surface roughness, and improve surface finish and hardness.
In addition, there is a complete set of process flow for electroplating wastewater treatment. Firstly, metal dross is removed by pre-treatment in a settling tank, and then the main metal elements are removed by treatment in an integrated wastewater reaction tank. Then the flocculent precipitates in the solution are further treated by using inclined plate settling plate, and finally the remaining precipitates are filtered through the filtering tank and discharged after meeting the national discharge standard.
