Molybdenum boat is one of the molybdenum products. It is also often used as an evaporation boat or a coated molybdenum boat. It is a high temperature resistant vessel. The molybdenum boat is made by high-temperature stamping of molybdenum sheets. It is divided into different types according to different processing methods, including stamping boats, folding boats, welding boats and riveting boats. It has good electrical conductivity, thermal conductivity, high temperature resistance, corrosion resistance and wear resistance. Therefore, it is mainly used in coating technology, electronics industry, power engineering and other fields, such as capacitor sintering, vacuum thermal evaporation, nuclear fuel sintering, thermocouple housing. Wait.
The invention relates to a method for processing a metal molybdenum vessel, relating to a method for processing metal molybdenum and molybdenum alloy vessels such as molybdenum crucible and molybdenum boat in a reduction and baking process in a metallurgical chemical process. The utility model is characterized in that the processing process adopts a molybdenum alloy plate with a thickness of 1.5 mm ≤ plate thickness ≤ 4 mm, and the mold is heated together with the molybdenum alloy plate to maintain the temperature of 400-1200 ° C, and the pressing speed of the control hydraulic machine is controlled at 5 mm/min- 1mm/min for a deep drawing. The method of the invention adopts a molybdenum alloy plate with high temperature strength and moderate plasticity, simultaneously heats and heats the mold and the plate, and slowly draws the hydraulic machine to form a metal molybdenum and molybdenum alloy vessel such as a box-shaped or circular molybdenum crucible or a molybdenum boat. The wall thickness is less than 1.5mm, and can effectively avoid the cracking, earing, wrinkles and the like generated during the drawing process, effectively reducing the defects of the molybdenum alloy vessel, increasing the yield, and prolonging the life of the metal molybdenum vessel.
