The production process of pure nickel alloy N4 mainly includes smelting, casting, rolling, and heat treatment. The following are the main production processes of pure nickel alloy N4:

Smelting

High-purity nickel raw materials are used, with appropriate amounts of chromium, iron, cobalt, and other elements added for smelting to obtain a high-purity nickel alloy melt.

Casting

The molten nickel alloy obtained is poured into a casting mold, and after cooling and solidification, castings are obtained. The casting process requires controlling parameters such as temperature and pouring speed to ensure the quality of the castings.

Rolling

The castings are rolled to produce the required plates, bars, and other products. During the rolling process, parameters such as rolling temperature, rolling speed, and deformation amount need to be controlled to ensure the mechanical properties and dimensional accuracy of the products.

Heat Treatment

The rolled products are heat-treated to adjust their microstructure and mechanical properties. The heat treatment process requires controlling parameters such as heating temperature and cooling rate to ensure the stability and reliability of product performance.
