Pressure processing for producing molybdenum rods, molybdenum wires, and molybdenum strips from sintered dense molybdenum strips is a typical process for swaging and drawing. In order to improve the quality and productivity of molybdenum processed materials, expand the variety and specifications of products, and reduce processing costs, rolling methods have been used instead of rotary forging. In order to improve the pressure processing type of molybdenum, the dense molybdenum strip requires high purity, high density, fine and uniform grain size. Preparation of Powder Metallurgy molybdenum usually have these conditions, the vacuum melting Preparation molybdenum products, although high purity, but generally the coarse grain structure, need to be pressed at 1400 ~ 1700 ℃, crystal grains becomes After the fine, the forging, drawing, and rolling are performed. The dense molybdenum strips (rods) obtained by powder metallurgy or vacuum smelting and extrusion treatment are subjected to swaging (or rolling), drawing and processing into various specifications of bars or wires, strips, and dense ingots thereof. Or the slab can be rolled into various specifications of molybdenum sheets, foils and the like. For the mechanism of molybdenum pressure processing, the selection of process parameters, and the quality of products, please refer to the reference "Handbook of Rare Metal Materials Processing" (Metallurgical Industry Press, Beijing, 1984) and "Progress in Molybdenum Metallurgy" (Xi'an Institute of Metallurgy and Architecture, Xi'an, 1980).
