Process for producing molybdenum crucible
Molybdenum crucible and tungsten crucible have been widely used in rare earth smelting, vacuum sintering, laser crystal growth and other industries, because of the expensive price and hard processing of tungsten and molybdenum, the repeated use of the crucible has become the concern of the majority of manufacturers.
According to he different methods of production, tungsten crucible and molybdenum crucible can be divided into sintering, stamping, machining, and welding molding.
In these forming molybdenum crucible products, the stamping type crucible is widely used, the price is relatively low, but affected by the processing technology, it has an inherent disadvantage: the thin thickness, it is not conducive to the long-term use, it has the poor performance in the repeated use.
As for the welding tungsten and molybdenum crucible, not only it has low price, but also due to the increase of the wall thickness, the use of time is greatly lengthened compared with the stamping crucible, which is praised by many manufacturers and has been the preferred type.
The welding process and welding environment as well as the selection of materials, and the appropriate heat treatment method determine the degree of durability of the welding type crucible.
If it is well done, the welding molybdenum crucible and sintering molybdenum crucible with the same thickness have same using temperature and using time. And the using time of some welding molybdenum crucibles is even much higher than the use of sintered crucible. This is because the sintered density is high, but it can not be compared with the density of the molybdenum plate which has been rolled over several times.
