Molybdenum alloy forging

Including rotary forging and ordinary forging. Rotary forging is mainly used to produce billets for thin rods and drawn wires with a diameter of more than 2.5 mm. The billets used are 10-30 mm square sintered bars. The forging temperature of pure molybdenum rotary forging is usually about 1400℃, and the deformation of pass is generally 10-20%, and it can reach about 30%. As the diameter decreases, the forging temperature gradually decreases, and it can drop to about 800°C with a diameter of 3 mm. For ordinary forging, hammer forging is more suitable than press forging. Ordinary forging can obtain large-size blanks and large forgings. The open forging temperature of pure molybdenum is about 1400°C, while the open forging temperature of the billet after extrusion can be lower. Pay attention to safety in free forging to prevent the workpiece or fragments from flying out and hurting people.
