Major specifications/special features.
Route editor
After the rolling process with more than 60% deformation, the density of molybdenum sheet is basically close to the theoretical density of molybdenum, so it has high strength, uniform internal organization and excellent high temperature creep resistance. Therefore, it is widely used in the production of sapphire crystal growth furnace reflection screen, cover plate, reflection screen in vacuum furnace, heating belt, connecting parts, sputtering target material for plasma coating.High temperature resistant boat and other products.
Technical Key Points
1: The technical key to the production of high quality molybdenum sheet is to grasp the quality of raw materials, standardize the operation procedures, and adopt reasonable production technology
2: The key to improve the surface quality of molybdenum sheet is to control the production quality of the end grinding process and the surface finish of the upper and lower surfaces, and then choose the advanced double-sided four-way grinding machine, so that the surface quality accuracy of the product can reach the advanced level in the world.
