Product Description

Metal casting machinery graphite crucible is one of the key components in metal casting machinery. It has become an important component due to its unique physical and chemical properties.

Graphite crucible has excellent high temperature tolerance and can work stably at extreme temperatures above 1500°C, meeting the smelting needs of common metals such as aluminum, copper, zinc and precious metals such as gold and silver.

The thermal conductivity of graphite crucible is higher than that of ordinary metals. Its use can significantly improve the efficiency of heat energy transfer, shorten the smelting time and reduce energy consumption. At the same time, graphite crucible also has excellent thermal shock resistance. In the face of rapid cooling and heating conditions, graphite crucible is not easy to crack and has a longer service life than ceramic crucible.

In addition, graphite crucible reacts inertly with most metal solutions, avoiding melt contamination, thereby packaging metal purity, which is particularly important for precision casting and precious metal processing.

Graphite crucibles are used in the core links of metal casting. For example, in aluminum alloy casting, the use of graphite crucibles can effectively block oxidation reactions and reduce slag formation; when melting copper alloys, the stable chemical properties of graphite crucibles can prevent solution carburization; in precious metal processing, the high purity of graphite crucibles can ensure the quality of gold and platinum products. Under the above working conditions, the use of graphite crucibles in conjunction with electromagnetic induction heating systems can achieve precise temperature control, which is particularly suitable for high-end manufacturing such as aerospace components.
