Abstract
Description
Technical Field
[0001] The utility model belongs to the field of crucible clamps, in particular to a clamp for a graphite silicon carbide crucible. Background Art
[0002] Graphite crucibles are primarily composed of natural flake graphite and a binder. They offer advantages such as fast thermal conductivity, high temperature resistance, excellent thermal stability, and a resistance to melt reactions, making them ideal for melting and casting non-ferrous metals. However, they are susceptible to oxidation when used in high-temperature, highly oxidizing atmospheres. Therefore, when providing various heat sources, highly oxidizing atmospheres should be avoided, as this can shorten their service life. However, with the advancement of production technology, some graphite crucibles are now coated with a multi-layered, special glaze to prevent graphite oxidation and enhance their corrosion resistance. However, the production of graphite crucibles generates considerable heat, and to remove the crucible, a clamp is required to grip the crucible from the outside to maintain its position. Existing clamps typically clamp directly on the crucible's outer circumference to lift the crucible. However, due to the lack of support for the crucible's bottom, the crucible can easily fall from the clamp during transfer after gripping.
[0003] Therefore, in view of the shortcomings of the above-mentioned solution in actual production and implementation, it was revised and improved. At the same time, in the spirit and concept of striving for excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created. In particular, a clamp for a graphite silicon carbide crucible is provided to solve the problem that the existing clamps mostly directly clamp the outer peripheral surface of the graphite crucible to achieve the lifting operation of the graphite crucible, but lack a lifting structure for the bottom of the graphite crucible, which makes it easy for the graphite crucible to fall from the inside of the clamp and be damaged during the transfer process after clamping.
