Abstract

The invention relates to the field of metal material preparation and solidification research, in particular to a centrifugal supergravity solidification device and method. The device comprises a test chamber, a main shaft composite assembly, a lifting driving system and a casting rotor. A vacuum test chamber is arranged in the test chamber, and a liftable chamber cover is arranged on a chamber opening; the upper end of the main shaft composite assembly rotatably penetrates through the cabin cover, and the lower end rotatably extends into the vacuum test cavity; the lifting driving system is positioned on one side of the test cabin; a lifting frame connected with the cabin cover is arranged at the lifting end of the lifting driving system; a driving structure is arranged on the lifting frame to act on the movable main shaft composite assembly, so that the movable main shaft composite assembly rotates to generate centrifugal supergravity; the casting rotors are symmetrically arranged at the lower end of the main shaft composite assembly and internally provided with a ventilation heating cavity communicated with the sample space. The in-situ melting-solidification-cooling process is automatically carried out, the functions are concentrated, the automation is high, heating and cooling treatment on the sample is efficient, and material preparation and solidification technology research are facilitated.
