[0002] Powder sintering is a process in which metal powder or powder compact is heated to a temperature below the melting point of the main component, and due to physical and chemical reactions such as bonding between particles, the material or product with the required strength and properties is obtained.

[0003] Magnetic materials are a type of material with strong magnetism, which are widely used in electronics, electrical appliances, computers, communications, medical treatment, automobiles and other fields. The production of magnetic materials is usually made through the processes of powder making - mixing - magnetic field orientation and pressing - sintering - tempering - machining.

[0004] At present, in order to improve the sintering efficiency of powder compacts, a continuous sintering machine is used to sinter the powder compacts, which is a method of sintering powder compacts. However, when sintering, multiple powder compacts are often stacked and sintered. Combined with the characteristics of powder compacts, uneven sintering of powder compacts is a common situation. In this case, there is a method of improving the uniformity of sintering of powder compacts by placing partitions between multiple stacked powder compacts. However, the actual situation is that the placement of partitions makes the placement of powder compacts more inconvenient, and when the powder compacts are moved through the partitions, there is also a risk of the powder compacts falling off.

[0024] There are multiple placement plates 4, and plug rods are provided at the four corners of the bottom end of the placement plate 4. The plug rods of the placement plate 4 are plugged into the inner side of the limit block 3. The middle part of the bottom end of the placement plate 4 is located above the mesh chain conveyor belt 2. A groove is provided at the top of the placement plate 4. The groove of the placement plate 4 is the same size as the middle part of the limit block 3, and is adapted to the plug rod at the bottom end of the placement plate 4. The groove of the placement plate 4 and the plug rod of the placement plate 4 are in the same horizontal position on the placement plate 4, and have a vertical distance, which is used to insert and stack multiple placement plates 4.

[0025] There are through holes on both sides of the placement plate 4, and the length of the through holes of the placement plate 4 is 3cm-6cm. When the staff moves the placement plate 4, the fulcrum is located at the top of the through holes of the placement plate 4, making the movement of the placement plate 4 more convenient.

[0026] A plurality of baffle rods 5 are provided on the inner side of the through hole of the placement plate 4, and there are gaps between the plurality of baffle rods 5, wherein the thickness of the baffle rod 5 is smaller than the length of the through hole of the placement plate 4, and the baffle rod 5 is vertically installed on the inner side of the through hole of the placement plate 4, so that the staff can increase the placement positions of their fingers when the placement plate 4 is moved, thereby facilitating the transportation of the placement plate 4.

[0027] The front, back and bottom surfaces of the placement plate 4 are all in a grid shape, so that the powder compact placed inside the placement plate 4 can be heated in all directions.

[0028] Working principle:

[0029] When in use, the powder compact is placed on the inner side of the placing plate 4, and the wider edge formed by the through hole of the placing plate 4 makes it easier for the placing plate 4 to drive the powder compact to move, and the bottom end of the placing plate 4 is plugged into the inner side of the limit blocks 3 installed on both sides of the mesh chain conveyor 2.
