Characteristics and uses of molybdenum foil
The production process of molybdenum foil mainly includes raw material preparation, smelting, rolling, annealing and cutting. First, high-purity molybdenum powder needs to be prepared as raw material, screened and ground to ensure the purity and uniformity of the raw material. Next, the molybdenum powder is mixed with other additives (such as iron, carbon, etc.) and smelted at high temperature to obtain a molybdenum alloy billet.
After the smelting is completed, the molybdenum alloy billet is rolled multiple times to gradually reduce the thickness to form molybdenum foil. The temperature and rolling intensity need to be controlled during the rolling process to ensure that the molybdenum foil has uniform thickness and good surface quality. The molybdenum foil is then annealed to relieve stress and improve its mechanical properties.
Finally, the molybdenum foil is cut as needed to get the desired shape and size. Cutting can be performed using mechanical cutting, laser cutting and other methods to meet the requirements of different applications.
To summarize, the production process of molybdenum foil includes steps such as raw material preparation, smelting, rolling, annealing and cutting. Each step requires strict control of parameters and process conditions to ensure the quality and performance of molybdenum foil.
