Application of graphite crucible

Graphite crucible has been applied to many fields, very popular with people, but as people continue to increase the requirements for products.
The main raw material of graphite crucible is crystalline natural graphite, so it has good heat transfer and high temperature resistance, strong corrosion resistance to acid and alkaline solutions, and excellent chemical stability. There are more types of graphite crucible, which is less restricted in application and can be chosen arbitrarily. Based on the above excellent properties, graphite crucible is widely used in metallurgy, casting, machinery, chemical industry and other industrial sectors. It can also be used for the refining and purification of non-ferrous metals and new materials. In order to benefit environmental protection, the international efforts to improve the weight ratio of light metals in industrial products. Therefore, aluminum, magnesium, zinc and their alloys are widely used in the production of automobiles, motorcycles and electronic supporting products. Such as die-casting production of automobile and motorcycle wheel hubs, engine cylinder heads, brakes, air filters, pistons, radiators, steering wheel skeleton and electronic products in the mobile phone shell.

Graphite crucible in use also need to pay attention to some matters, because the bottom of the crucible is very small, the crucible needs to be placed on the graphite pad or mud triangle when heated. The graphite crucible can be directly heated, and cannot be cooled immediately after heating. Take it off with the crucible pliers and do not put it on the cold metal table to avoid it from cracking due to sharp cooling. Note that the above points can extend the life of the graphite crucible.
