Supergravity directional solidification melting furnace equipment, comprising a supergravity test chamber (C) and, mounted in the supergravity test chamber (C), a high-temperature heating subsystem, a crucible, and a gas cooling system. The supergravity test chamber (C) is mounted with a wiring electrode (C5) and a cooling gas valve apparatus (C9). The high-temperature heating subsystem is fixed in the supergravity test chamber (C). The crucible and the gas cooling system are provided in the high-temperature heating subsystem. The high-temperature heating subsystem comprises upper, middle, and lower furnaces, a mullite insulating layer (16), upper and lower heating cavity outer bodies (17 and 18), upper and lower heating furnace pipes (19 and 20), and a crucible supporting base (21). A high-temperature heating cavity is divided into upper and lower parts, is provided therein with a spiral groove (22-1), and is fitted with a heater (22). The crucible supporting base (21) is provided therein with a ventilation pipe (21-1) into which a cooling gas is introduced. The crucible and the gas cooling system comprise intake and exhaust pipes (29 and 30), a cooling base (26), a cooling rate adjusting ring (27), the crucible (25), and an exhaust cover (28).
