How to extend the life of Corundum Crucible?

Importance of Corundum Crucible

Corundum Crucible plays a vital role in the high-temperature smelting process. Its excellent heat resistance and chemical stability make it ideal for metal smelting. However, how to extend the service life of Corundum Crucible is the focus of many industrial users.

Gradient sintering technology

Gradient sintering technology is a method of gradually increasing the temperature to form a gradient structure of the material during the sintering process, thereby improving its overall performance. For Corundum Crucible, gradient sintering can effectively reduce internal stress and enhance its thermal shock resistance, thereby extending its service life.

The role of silicon nitride coating

Silicon nitride coating has extremely high hardness and wear resistance and can effectively resist the erosion of molten metal. By applying a silicon nitride coating on the surface of Corundum Crucible, its corrosion resistance can be significantly improved, allowing it to maintain stable performance during multiple melting processes.

Achieved more than 200 melting cycles

Combining gradient sintering technology and silicon nitride coating, the service life of Corundum Crucible can be significantly extended. Experiments show that the optimized Corundum Crucible can achieve more than 200 melting cycles, greatly reducing replacement frequency and cost.

in conclusion

By adopting gradient sintering and silicon nitride coating technology, the service life of Corundum Crucible can be effectively extended, its erosion resistance can be improved, and more than 200 melting cycles can be achieved. This not only improves production efficiency, but also reduces operating costs, bringing significant economic benefits to industrial users.
