Our company produce molybdenum sheet by powder metallurgy process.
First of all, compress molybdenum powder into plate shape with isostatic pressing technology, sinter under high heat to make the production into molybdenum slab, and then roll. Because of the multiple deformation and fast speed in the process of rolling, so no need to repeated heat. This is very good for molybdenum because of its serious oxidation under high temperature and the rapid volatilization of the oxide. At the same time, to manufacture molybdenum sheet production by the method of the breakdown of rolling, not only conducive to the internal sintered bore welding of molybdenum billet, the grain fully broken, and also improved the uniformity of deformation distribution along the cross section, Reduced the fracture probability in the process of drawing. It is the standard ductile necking fracture. Markedly improve the mechanical properties of materials and internal quality. In addition, molybdenum sheet changes with deformation in succession in the process of rolling. So the surface roughness and wrinkling of the molybdenum sheet is improved, and the defects such as the surface burr and the concave surface are reduced. In the process of temperature in hot rolling, warm rolling, cold rolling we adopt cross rolling technology with the unique annealing temperature control, the internal organization of molybdenum sheet is formed in pie shape throughout the entire rolling process. The internal organization of vertical and horizontal overlap, grain size distribution is more uniform, effectively avoid the defects caused by the uneven stress, and the crack growth of molybdenum plate can be blocked.
