Tungsten Alloy Crucible
Description:
Tungsten crucible is formed by turning and welding tungsten rods.
It is made of pure tungsten plates, tungsten sheets and pure
tungsten rods through corresponding processes. There are many
preparation methods. It is widely used in rare earth smelting,
quartz glass, crystal growth and other industries, and plays a
major role in modern industry.

Application:
1. Isostatic pressing-sintering method
2. Forging processing method
3. Chemical vapor deposition method
4. Plasma spray forming method
5. Spin forming method
6. Riveting forming method
Among these six preparation methods, three are most commonly used:
isostatic pressing-sintering method, forging processing method and
riveting forming method. Most products are made by these three
methods. Another chemical vapor deposition method can prepare
high-purity, dense, and large-sized products, making people full of
expectations for its future development.
AbThe isostatic pressing-sintering method mainly includes six
processes: raw material batching, powder loading, isostatic
pressing, high-temperature sintering, turning, and finished product
inspection. The steps are as follows: Assemble the mold according
to the size of the blank charging requirements, load the tungsten
powder raw material that meets the national standard requirements
into the mold and seal it, put it into a cold isostatic press for
pressing, the forming pressure is generally 180~250 MPa, and then
press The billet is placed in a high-temperature induction
sintering furnace for sintering. The heating rate is 80~150℃/h, the
maximum temperature is 2200~2400℃, and the high temperature holding
time is 4~8 h. The sintered billet is processed according to the
requirements of the finished product, and finally the finished
product is Conduct quality inspections such as appearance, size,
density, etc.
