Abstract: Provided is a supergravity directional solidification melting furnace equipment, including a supergravity test chamber and, mounted in the supergravity test chamber, a high-temperature heating subsystem, a crucible, and an air-cooling system. The supergravity test chamber is mounted with a wiring electrode and a cooling air valve device. The high-temperature heating subsystem is fixed in the supergravity test chamber. The crucible and the air cooling system are provided in the high-temperature heating subsystem. The high-temperature heating subsystem includes upper, middle, and lower furnaces, a mullite insulating layer, upper and lower heating cavity outer bodies, upper and lower heating furnace pipes, and a crucible support base. A high-temperature heating cavity is divided into upper and lower parts, is provided therein with a spiral groove, and is fitted with a heating element. The crucible support base is provided therein with a vent pipe channel into which a cooling air is introduced. The crucible and the air cooling system include air inlet and exhaust pipes, a cooling base, a cooling rate adjustment ring, the crucible, and an exhaust cover.
