The hanging cup is suspended on the end portion of a rotating arm of a supergravity centrifugal machine in a hinged manner through lifting lugs on the two sides. According to the cantilever type centrifugation supergravity casting device, by carrying a high-temperature casting furnace or the directional casting furnace, a supergravity directional solidification function is achieved through a power reducing method in the centrifugal supergravity environment, the key problem that in the supergravity directional solidification process, the temperature gradient is hard to control is solved, and operation is convenient, safe and reliable.

Description

technical field [0001] The invention relates to a high-gravity material preparation device in the technical field of material preparation and directional solidification, in particular to a cantilever type centrifugal high-gravity casting and directional solidification device. Background technique [0002] Usually, in order to improve the comprehensive mechanical properties of the alloy, two ways are adopted: one is to add a large amount of alloying elements, and through a reasonable heat treatment process to produce solid solution strengthening, precipitation strengthening and grain boundary strengthening, etc., so as to ensure that the alloy has properties from room temperature to Good strength at high temperature, indicating stability and good plasticity; the second is to start with the solidification process and adopt the directional solidification process to prepare the columnar grain structure with grain boundaries parallel to the principal stress axis to eliminate harmf...

Problems solved by technology

[0003] However, the melting and casting system of existing high-gravity melting and casting equipment has no heating function, and can only be cooled with the furnace. The solidification process is uncontrolled, and the samples are small, so only composition optimization can be performed, and performance testing cannot be performed. Therefore, composition optimization based on high-gravity technology It is seriously out of touch with performance testing, and it is impossible to realize the preparation of hypergravity materials based on material performance requirements, and because of the nonlinear relationship between material composition-structure-performance, it is difficult to realize the integrated research method of material design and preparation for actual performance requirements
