Description

Technical Field

[0001] The utility model relates to the technical field of sintering equipment, in particular to a sintering equipment for ferrite permanent magnet materials. Background Art

[0002] Magnetic materials refer to materials that can respond to magnetic fields in some way. According to the strength of the magnetism exhibited by the material in the external magnetic field, it can be divided into diamagnetic materials, paramagnetic materials, ferromagnetic materials, antiferromagnetic materials and ferrimagnetic materials.

[0003] Ferrite permanent magnet materials need to be sintered using sintering equipment during the processing process. However, after sintering, the temperature inside the furnace is high, and it is necessary to wait for the furnace to cool naturally before opening the furnace, which wastes a certain amount of production time. In addition, the exhaust gas in the furnace will be discharged during the opening process, causing pollution. For this reason, we propose a sintering equipment for ferrite permanent magnet materials.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The sintering equipment of the ferrite permanent magnet material turns on the switch of the exhaust device so that the air inlet pipe can absorb air. The wind passes through the connecting pipe into the heat sink. The hot air transfers the temperature to the heat sink and the heat sink outside the heat sink for rapid heat dissipation. The arc filter filters the hot air passing through the heat sink and can filter out impurities in the hot air. After a certain period of filtering and heat dissipation, the temperature in the sintering furnace is reduced and the exhaust gas is filtered clean. At this time, opening the furnace can prevent pollution and high temperature.
