Description

Technical Field

[0001] The utility model relates to the technical field of aluminum nitride sintering frames, in particular to a sintering frame with uniform heating. Background Art

[0002] Sintering is an indispensable process in the processing of aluminum nitride. The nitriding furnace that needs to be sintered is hung on the sintering rack through a hook, and then the entire sintering rack is placed in the sintering furnace for sintering. However, the existing sintering rack generally adopts a multi-layer design, and the distance between the layers is fixed. When the specifications of aluminum nitride are different, the nitriding furnaces are easily stacked on each other, resulting in uneven heating of the nitriding furnace. In addition, the number of hangers is small, so the amount of aluminum nitride that can be sintered at one time is small, and the space utilization rate in the sintering furnace is not high.
