Production Process
The tungsten and molybdenum products produced by our company are all produced by powder metallurgy method, which is also the traditional method for preparing moly sheets.
First, the molybdenum powder is pressed into a predetermined shape and then sintered at high temperature. During this process, the powder particles will fuse to form a solid structure. Powder metallurgy can effectively control the thickness and size of the moly sheet and is suitable for producing moly sheets of various specifications.
Generally speaking, there are two main manufacturing processes for moly sheet: hot rolling and cold rolling. Hot-rolled moly sheets are rolled into plates by heating molybdenum blocks blanks at high temperatures through rolling machinery equipment, so they have higher strength and wear resistance, and are suitable for use under high-strength and high-temperature conditions; while cold-rolled moly sheet are rolled into plates or sheets by rolling mills at room temperature, so they have better surface smoothness and dimensional accuracy, and are suitable for applications with high surface requirements.
After rolling with a deformation of more than 60%, the density of the moly sheet is basically close to the theoretical density of molybdenum. Therefore, it has high strength, uniform internal structure and excellent high-temperature creep resistance. It is widely used in the production of reflective screens and cover plates in sapphire crystal growth furnaces, reflective screens, heating belts, connectors in vacuum furnaces, sputtering targets for plasma coating, high-temperature resistant boats and other products.
