Large Graphite Crucible

Large graphite crucible for sale

Large graphite crucible usually has a large volume and a strong structure, has many advantages.

Excellent high temperature resistance

It can withstand high temperatures of up to thousands of degrees Celsius, can meet the needs of most metal melting. Graphite crucible has a wide temperature range and a high melting point, which can adapt to the temperature requirements of a variety of metal melting.

Good thermal conductivity

It can transfer heat quickly and evenly to the smelted material, accelerate the melting process, improve production efficiency.

Stable chemical properties

It is not easy to react with metals and other melting additives at high temperatures. This can effectively ensure the purity of metals.

High mechanical strength

It can withstand the impact of liquid metal and its own weight. And it is not easy to break and deformation, long service life.

Low thermal expansion coefficient

The size changes are small during repeated heating and cooling. This can maintain good structural stability and reduce the risk of damage caused by thermal stress.

Types of large graphite crucibles

High purity large graphite crucible

Graphite purity up to 99% and above, this crucible has better stability and corrosion resistance at high temperatures. You can often use it for melting some high purity metals or special alloys with strict impurity content requirements.

Extrusion molding graphite crucible

Through the extrusion process to make the graphite material molding, this crucible has a high density, uniform structure, good strength. It is suitable for large metal smelting enterprises, can withstand the larger liquid metal capacity and frequent use.

Isostatic pressure graphite crucible

The use of isostatic pressure technology manufacturing, its internal structure is more dense, more excellent performance. Especially in the thermal shock resistance and corrosion resistance is outstanding. You can often use the crucibles for melting some high value, refractory metal, but its production cost is relatively high.

Uses of large graphite crucible

The application field of large graphite crucible is concentrated in high temperature melting.

In the metallurgical industry

Used in the smelting of steel, non-ferrous metals,  etc., it can withstand high temperature environment. And provide stable container conditions for metal refining and alloying, ensure the uniformity and stability of metal quality.

In the field of casting

Whether it is sand casting or precision casting, large graphite crucible is an important tool for melting metal liquid. It can melt various metal raw materials into liquid metal that meets the requirements of the casting process. Pour it into the mold and form it to produce various mechanical parts, auto parts, aviation parts, etc.;

In the laboratory

For some small high-temperature melting experiments, you can also use graphite crucible for melting and sample preparation of a small number of high-purity metals. It provides accurate and reliable experimental conditions for scientific research.

In some emerging material preparation fields

Such as high temperature superconducting materials, advanced ceramic materials synthesis process, large graphite crucible also plays a key role. Its stable high temperature performance and chemical inertia for the development of new materials to provide a strong guarantee.

For large crucibles that need to be used to melt aluminum, you can select suitable large graphite crucibles according to the specific production needs. And the price of graphite crucible due to size, purity, process and other factors are different. You can choose according to your own needs and budgets when buying. At the same time, we will provide large crucible sales services. The graphite crucibles sizes are diverse to meet the needs of different users.
