High Density Forged Tungsten Crucible
1. Description of High Density Forged Tungsten Crucible:
The forging process used for forging tungsten crucibles is
relatively mature, and the forged tungsten crucibles produced have
high density and good performance. The density of the forged
tungsten crucible is generally greater than 19.0g/cm3. Because its
density almost reaches the ideal theoretical density and the
service cycle is long, the tensile strength and high temperature
deformation resistance of the forged tungsten crucible will be
higher than that of other types of tungsten crucibles. Better
performance.
2. Size of High Density Forged Tungsten Crucible:
Purity | Density | Size | Tolerance (mm) | Wall thickness | Surface | |||
99.95% | ≥19.0g/ cm3 | Diameter(mm) <100 | Height(mm) 10-750 | Tolerance of diameter +/-5.0 | Tolerance of height +/-5.0 | 8-20 | Ra=1.6 |
3. High Density Forged Tungsten Crucible Manufacturing Process:
The preparation of the tungsten crucible by the forging method is
mainly completed through three steps. They are billet preparation,
forging and machining respectively. In general, the relative
density of the billet is 90%-95%. When preparing the billet, the
required size and quality of the tungsten rod should be calculated
according to the requirements of the finished product. Then the
prepared billet, that is, the tungsten rod, is put into a hydrogen
furnace for heating, and the temperature should be increased to
1400-1600 °C. After holding for a period of time, forging and
forging are carried out, and then the billet is heated and forged
several times again until the size of the billet meets the
requirements. After the forging is completed, the billet is
annealed and then dimensioned according to the requirements of the
finished product.
4. High Density Forged Tungsten Crucible Benefits:
Affected by equipment and forging process, the size of forged
tungsten crucible is relatively small, generally less than 100mm in
diameter. The final finished tungsten crucible is made of tungsten
rod, and the utilization rate of the material is not high.
Tungsten crucibles of various sizes can be customized according to
customer requirements.
