Molybdenum Crucible For Smelting Metal
1. Description of Molybdenum Crucible For Smelting Metal:
A common type of container used in the metallurgical, rare earth, monocrystalline silicon, solar energy, artificial crystal, and machining sectors is the molybdenum crucible. It is produced by using Mo-1 molybdenum powder.Work in the environment of 1100~1800℃.
2. Production Process of Molybdenum Crucible For Smelting Metal:
The following describes a molybdenum crucible manufacturing process and its specific steps are as follows:
1) Using molybdenum powder as raw material;
2) Produced with cold and other fine presses;
3) Sintering treatment;
4) Use flowing water to cool the intermediate frequency sintering furnace for 9 to 10 hours after sintering;
5) Remove the molybdenum rod and warm it up in the muffle furnace;
6) Take out the molybdenum rod, use an air hammer with an impact force of 1000 kg, and forge it 30-40 times;
7) The molybdenum crucible is created by machining the groove, the outer circle, and the end face until the molybdenum crucible's surface roughness reaches Ra1.6-Ra3.2m.
The molybdenum crucible manufactured by this process has the advantages of reducing cost and requiring less equipment. It is first made into a solid powdery cylindrical billet, and then undergoes secondary high-temperature crystallization to refine the grains, which improves the strength and resistance of the crucible. high temperature.
3. Size of Molybdenum Crucible For Smelting Metal:
Sintered Molybdenum Crucible:
Molybdenum content: ≥99.95%
Density: ≥9.6g/cm3
Specifications: Molybdenum crucibles of various sizes can be customized according to customer requirements, and the high precision requirements of users can be met through machining.

5. Application of Molybdenum Crucible For Smelting Metal:
Because molybdenum has the characteristics of high temperature resistance and low pollution, it is used to make crucibles and accessories and high temperature containers for crystal growth and rare earth smelting, as well as rare earth metal smelting. Molybdenum crucible can be said to be a rare earth smelting container, mainly used in metallurgy, machinery and other industries.
For metallurgical industry and machining industry. Sintered tungsten crucible and sintered molybdenum crucible have low impurity content and good processing performance, which can improve the yield of subsequent processing products such as forging and rolling.
Molybdenum crucible is an indispensable material in the rare earth smelting industry. It is increasingly used in emerging high-tech industries such as crystal materials.
