Molybdenum and molybdenum alloy crucible
Molybdenum and molybdenum alloy crucible shell is variable wall thickness, variable section of rotary parts, the bottom diameter is smaller than the diameter of the mouth, the bottom wall is thick, the mouth wall is thin, molybdenum and molybdenum crucible is the metallurgical industry, with the advantages of high temperature resistance. The current process adopts the method of sheet metal stamping and machining.
Molybdenum and molybdenum alloy crucible shell parts spinning processing method, using plastic forming process method, due to the poor plasticity of molybdenum and molybdenum alloy at room temperature, high strength, need to be formed at high temperature, through the spinning forming of molybdenum and molybdenum alloy internal organization has been refined, improve the quality and performance of the product. The blank is made of sheet material or thick wall stamping parts, and the blank is reduced from the previous 50kg to 30Kg. Spinning process route: plate - spinning preformed cylindrical parts or stamped cylindrical parts - vacuum heat treatment annealing - hot spinning final forming - cleaning - vacuum heat treatment - finishing machine.
