Large diameter molybdenum alloy melting crucible
Molybdenum alloy in molybdenum based join other alloy elements, in refractory metal molybdenum and its alloys have good thermal conductivity, electrical conductivity and low expansion coefficient, at high temperatures (1100 ~ 1650 ℃) has high strength, compared with the tungsten, easy processing, thus in electron tubes, electric light source, metal processing tools manufacturing sector and has been applied in the aerospace industry.
At present, the traditional melting crucible made of molybdenum or molybdenum alloy materials is generally a hollow cylindrical structure, the upper end of the crucible is open, the lower end of the crucible is closed, constituting the molybdenum crucible body, the wall thickness of the molybdenum crucible is usually consistent. For the melting molybdenum crucible with large diameter, due to the increase of the weight of the melting material and the influence of high temperature, the strength of the crucible body of molybdenum alloy decreases after long-term use, and it is easy to form fine cracks at the opening end of the crucible, thus affecting the service life of the crucible.
Large diameter molybdenum alloy melting crucible, made of molybdenum or molybdenum alloy material for hollow cylindrical structure, the upper end of the opening, the lower end is closed, the outer circumference of the molybdenum crucible near the upper end of the opening is provided with a thickened strengthening layer, so that the strength of the true and false crucible can be effective. Increase the service life of molybdenum alloy crucible.
We can produce and process molybdenum and its alloy crucible according to customer requirements.
