Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet processing, in particular to a sintering air intake structure for permanent magnet processing. Background Art

[0002] One of the commonly used methods for permanent magnet processing is to use sintering technology. Sintering is a method for preparing ceramic materials or metal materials. After the powder material is pressed into shape at high temperature, it is heated in a controlled atmosphere to diffuse its particles into each other to form a dense block structure. The sintering furnace plays a very important role in permanent magnet processing and can help permanent magnet materials obtain the required mechanical properties and magnetic properties. In permanent magnet processing, permanent magnet material powder is usually first mixed with a specific binder, pressed into shape, and then placed in a sintering furnace for sintering. During the sintering process, the powder particles diffuse into each other, and the binding force between the particles is enhanced, thereby forming a dense permanent magnet structure. The sintering furnace can usually control the temperature, atmosphere and time to achieve the desired sintering effect. Most existing sintering furnaces use a single pipe to cool the internal air intake during use. The single pipe has a slow inflation speed and requires more time for cooling, which reduces the efficiency of permanent magnet processing and is prone to uneven inflation, thereby affecting the processing quality of the permanent magnet.
