High-temperature resistant turns bowl

Abstract

The invention relates to the field of production of a turns bowl, in particular to a high-temperature resistant turns bowl. The invention aims to provide the high-temperature resistant turns bowl which can be used for preventing from generating a concave-convex point or being deformed during the sintering process of a magnetic core. In the technical scheme, the high-temperature resistant turns bowl comprises a turns bowl main body, wherein a load bearing plate is arranged on the turns bowl main body, a surface of the load bearing plate is coated with zirconium oxide, the thickness of the zirconium oxide is 0.05-1 millimeter, a plurality of limitation grooves are formed in the load bearing plate, a limitation plate is arranged under the turns bowl main body, a plurality of limitation pieces are arranged on the limitation plate and are used for limiting the magnetic core to move or deform during the sintering process, and the limitation pieces penetrate through the limitation grooves and extend out of an upper surface of the load bearing plate. By the high-temperature resistant turns bowl, the concave-convex point, deformation or damage can be prevented from being generated during the sintering process of the magnetic core, and the rejection rate of the magnetic core is reduced.

Description

technical field [0001] The invention relates to the field of bowl production, in particular to a high-temperature resistant bowl. Background technique [0002] The magnetic core needs to be sintered in the process of processing, so that the sintered product has the advantages of good surface appearance consistency, fine product cross-section, no large crystals, no oxidation and reduction phenomena, and good product performance consistency. However, the magnetic core is generally very small, and it needs to be placed in the magnetic core bowl during the process. The placed magnetic core needs to be heated up, kept warm, and cooled during the sintering process. During these processes, it is necessary to ensure that the Heating is uniform, and the magnetic core turns are stacked in layers. At this time, it is necessary to realize convective exchange between the layers of magnetic core turns to ensure uniform heat. [0003] The invention patent with the patent application numbe...

AI Technical Summary

Problems solved by technology

[0004] The above magnetic core turning bowl can increase the heat convection during the sintering of the magnetic core, but the bottom surface of the turning bowl main body is provided with convection holes, so that the bottom surface is uneven, which will cause the magnetic core to deform during sintering

In the prior art, when the magnetic core is sintered, a layer of corundum is usually sprinkled on the setter, so that after the magnetic core is sintered, there will be bumps on the side in contact with the corundum.

When the magnetic core is sintered, the stacking method is usually used. Since the magnetic core product is too small, the sintered magnetic core is easily deformed and twisted.

To sum up, when the magnetic core is sintered with the existing turning bowl, it is easy to produce concave-convex points or deformation, and the reject rate of the product is high
