Difficulty in cutting of wear plates and suitable cutting process

1. The difficulty of cutting the wear plate

In fact, cutting wear plates is as simple as cutting ordinary low carbon and low alloy steels. The key is to prevent cracks on the surface of the material. Since the wear plate has a wear layer, the thickness and hardness of the wear plate are certainly higher than that of the ordinary plate, so the probability of cracking when cutting is higher, especially the position of the edge of the wear plate.


2. Measures to prevent cracks during the cutting process of wear plates

Therefore, when cutting the wear plate, preheating is also performed in advance, and the height of the preheating temperature is determined by the thickness and quality level of the wear plate. At the same time, low-speed cutting can be used, but this is the way to use the full-page preheating.

In fact, the use of the correct slow cooling method is also beneficial to reduce the cracking of the wear plate. For the just-completed cutting, the wear-resistant plate with temperature can not be stacked, and it should be covered with a heat-insulating blanket to gradually reach Cooling requirements.

For the cutting of the wear plate, there is also a special measure, that is, heating immediately after cutting, that is, low temperature tempering, can effectively eliminate the cutting residual stress and reduce the occurrence of cracks.


3. water jet cutting for wear plate cutting

The key point is to introduce water jet cutting, which can be applied to the cutting of wear plates, and the effect is very good. Not only the heat affected zone of the cutting is small, but also the original performance of the workpiece is prevented from being affected. The key is that the obtained cutting quality is good and there is no deformation. Therefore, if you want to cut the wear plate in the future, you should use water jet cutting.
