NEW-TYPE VACUUM SINTERING FURNACE FOR NEODYMIUM IRON BORON SINTERING

WIPO Patent Application WO/2021/062655

A1

Disclosed is a new-type vacuum sintering furnace for neodymium iron boron sintering. The new-type vacuum sintering furnace comprises a medium-frequency power source (1), a vacuum pump (2), a wiring pipe (3), a vacuum pipe (4), a furnace body (5), a base (6), a furnace cover (7), a thermometer (8), a water inlet pipe (9), a water pump (10), a water outlet pipe (11), and a water storage pool (12), wherein the medium-frequency power source (1) is connected to the furnace body (5) by means of the wiring pipe (3); the vacuum pump (2) is arranged on one side of the medium-frequency power source (1), and the vacuum pump (2) is connected to the furnace body (5) by means of the vacuum pipe (4); and the furnace body (5) comprises a crucible (51), a heat insulation plate (52), a magnetic induction coil (53), and a furnace wall (54), with the crucible (51) being fixed in the furnace body (5) and on the upper end of the heat insulation plate (52). By arranging the vacuum pump (2), the water pump (10) and the heat insulation plate (52), the structure is simple, thereby facilitating reducing the highest temperature required for sintering a neodymium-iron-boron magnet, reducing energy consumption, and facilitating market popularization and application.
