We all know that the inductor is an important part of the medium frequency induction heating machine and is necessary for the heat treatment of the workpiece. During use, affected by various factors, the sensor may suffer damage such as burns, blowouts, deformation, and positioning block wear. Today, we will briefly talk about the causes of sensor burn damage.
1) The coil collides with the workpiece. The reason is that the coupling gap is too small, it may be that the coil is deformed or the spacer positioning block is worn beyond the limit. A German induction heating equipment factory stipulates that the wear of the spacer positioning block cannot exceed 0.3D (D is the distance between the inner diameter of the effective ring and the contact end of the positioning block).
2) If the journal surface is not clean, the remaining iron filings will be magnetically attracted and form a shell with the oil residue of the total loss system. The shell will form a conductor between the coil and the workpiece. When heated and energized, sparks will be generated, causing the journal surface and coil surface to be burned at the same time. Therefore, whether the crankshaft journal is cleaned before quenching is an important factor in determining the service life of the inductor.
This article briefly introduces the reasons for sensor burn damage and hopes to be helpful to your work. Here, the editor also reminds everyone that you must pay attention when working to avoid such damage and unnecessary losses.
