Advantages of Graphite Crucible for Aluminum
Generally, graphite crucible used for aluminum has various specifications and shapes and its advantages are very significant.
Excellent high-temperature resistance
It can withstand temperatures as high as over 1000°C, which far exceeds the melting point of aluminum around 660°C. So it ensures stability and reliability during the aluminum smelting process.
Extremely stable chemical properties
It has excellent resistance to erosion of molten aluminum, preventing chemical reactions between the crucible material and aluminum. And it can ensure the purity of the molten aluminum.
Excellent thermal conductivity
It can evenly transfer heat, promote the rapid melting of aluminum and shorten the smelting time.
High mechanical strength
It can withstand the gravitational force and stirring of molten aluminum and other external forces, which is not easy to break.
Smooth inner wall
This is helpful for the pouring and shaping of molten aluminum and reduces the residue of molten aluminum. So it improves the utilization rate of materials.
Long service life
Under normal usage and maintenance conditions, you can reuse it many times, which effectively reduces production costs.
Uses of Graphite Crucible for Aluminum
Foundry industry
Aluminum casting production:
You can use it to process of casting various aluminum parts, such as engine blocks, cylinder heads, and wheels of automobiles. It can be used to hold molten aluminum and smoothly pour it into molds. It ensures the purity of the molten aluminum and the quality of the forming process, and produces high-precision and high-quality aluminum castings.
Sand casting:
In this casting process, you should precisely inject the molten aluminum in the graphite crucible into the cavity of the sand mold. And after cooling and solidified, you can obtain the aluminum products that meet the requirements.
Aluminum smelting industry
Primary aluminum purification:
During the refining and purification process of primary aluminum, you can use graphite crucible as a container. It can operate stably at high temperatures, helping to remove impurities from the molten aluminum. And it also improves the purity of aluminum and meets the quality requirements of different industries for aluminum.
Alloy smelting:
When producing aluminum alloys, you can place aluminum and other alloying elements in a graphite crucible for smelting together. Uniformly mix the components can prepare aluminum alloy materials with specific properties, such as hard aluminum and super-hard aluminum. And you can use them in aerospace, transportation and other fields.
Other fields
Research and experimentation:
Research and development of new aluminum materials
You can use it to carry out smelting experiments under different temperature and atmosphere conditions.
In the material performance testing experiment
You can use it for small-batch smelting of aluminum samples with specific components to prepare standard samples. It can provides a basis for material performance analysis.
Recycled aluminum recycling:
It can separate aluminum from impurities and achieve the recycling of aluminum resources. When dealing with waste aluminum from different sources and with complex compositions, its anti-corrosion property ensures that it is not corroded and guarantees the stable quality of recycled aluminum.
