Description

Technical Field

[0002] Graphitized crucible is a kind of laboratory equipment used for high temperature heat treatment. It is usually made of refractory graphite. Graphitized crucible has good high temperature resistance and can withstand extremely high temperatures, usually up to thousands of degrees Celsius. It is suitable for experiments and treatment processes under high temperature. Graphite material has good thermal conductivity and can conduct heat quickly and evenly, which is very important for some experiments that require rapid heating or temperature control.

[0003] When the graphitized crucible is conducting a high-temperature test, some samples may react with the air or other substances in the environment at high temperature, causing changes or damage to the samples. In this case, sealing the samples in the graphitized crucible can provide protection to prevent the influence of external substances on the samples. However, since the temperature of the graphitized crucible is relatively high at this time, when the staff manually places the cover, the high temperature released by the graphitized crucible directly rushes to the staff's hands, making it easy for the staff to get burned due to contact with the high-temperature surface. Therefore, we propose an automatic cover installation device for graphitized crucibles. Utility Model Content
