Interceptor teeth is the coal mining machine wearing parts, is often need to replace the part, the quality of the interceptor teeth related to the efficiency of mining, both the interceptor tooth manufacturers or users, should be able to distinguish the quality of the interceptor teeth, so that you can bring you a good benefit. So how to identify the quality of cut-off teeth good or bad?

In fact, the good or bad of the teeth depends on the strength, wear resistance and life of the teeth, in addition to the purchase of the above points but also to observe the size of the teeth is consistent. Strength depends on the quality of the material used, that is, the quality of the carbide, to understand the manufacturer of the carbide used, to see whether it is a regular factory products. Whether after heat treatment, at the same time to understand the heat treatment process, and can reach how many degrees, whether the surface oxidation, whether isothermal quenching process.

Cutting gear products are used in the non-sparking production process, so that the cut-off teeth more wear-resistant. To improve the wear resistance of the interceptor teeth, you can use wear-resistant welding rods to burnish wear-resistant strips in the taper part; use plasma spray welding wear-resistant layer in the taper part; braze carbide wear-resistant rings in the taper part. The alloy head is the part of the tooth structure that is very easy to be damaged, protecting the alloy head of the tooth will greatly improve its service life.

As for wear resistance, it depends on whether there is a wear-resistant layer, today's cut-off teeth usually have two kinds, one is with wear-resistant layer, one is not with wear-resistant layer. To understand the placement of the gear and the layout of the gear, if it is with wear-resistant layer, we should know the wear-resistant layer of material, know the source of the material, as well as the choice of what kind of skills for the treatment of wear-resistant layer.
