Tungsten Crucible Production Technology
According to the tungsten crucible production technology, tungsten crucibles can be classified into: sintered tungsten crucible, stamped tungsten crucible, machined tungsten crucible and welded tungsten crucible.
The tungsten crucible is widely used in rare earth smelting, vacuum sintering, laser crystal growing and other industries. Because of tungsten price is expensive and the processing conditions are severe, so the repeated use of tungsten crucible becomes the concern of majority of manufacturers.
Stamped tungsten crucible is mostly used. The price of stamped tungsten crucible is relatively cheap, so stamped tungsten crucible is widely applied. But stamped tungsten crucible has one shortcoming-thin thickness which is affected by the processing technic. This shortcoming is not conducive to long-term application and repeated use of stamped tungsten crucible.
While, for welded tungsten crucible, the price of welded tungsten crucible is low. At the same time, due to the thickness is increased, which prolongs the service life of welded tungsten crucible. So welded tungsten crucible is favored by many manufacturers.
The fact is that sintered tungsten crucible is more easily to be used than welded tungsten crucible.
Sometimes welded tungsten crucible would have pitting and damnification. These problems are mainly enslaved to technics used in tungsten crucible, welding environment and the selection of materials. In addition, whether there is suitable heat treatment after welding is also related to these problems.
Zhengzhou Sanhui Co., Ltd has been dealing in refractory metal for over 24 years. Our factory is located in Luoyang. We offer comprehensive metal products, including titanium, molybdenum and other metal products.
