What are the advantages of Carbide Coal teeth?

Carbide coal picks are composed of carbide ball teeth brazed and alloy structural steel. They are generally used for shearers to directly cut and mine coal, so they are also called carbide coal picks.

What are the advantages of tungsten carbide coal picks?

1. There are many types and shapes, which can be adapted to different working conditions. The working environments encountered by coal shearers are different. For example, if the hardness of some coal rocks is low, engineers must use picks with the same hardness. Otherwise, they need to use the same type of picks with high hardness.

At present, the common shapes of shearer picks are flat and pick-shaped. Among them, the flat pick is suitable for cutting coal with different hardness, such as hard type and sticky type. The pick-shaped pick is more suitable for brittle coal. This greatly extends the service life of different picks.

2. The equipment for picking and fixing the pick itself is simple. In order to improve engineering efficiency, the picks produced now are very user-friendly. Not only can engineers quickly install and fix them, but they can also be easily disassembled and maintained after use.

3. It has good wear resistance and more exquisite production technology, truly achieving high quality and low price. It is understood that the materials used to make picks are now more in line with the environmental needs of construction workers. Not only do they have good wear resistance, but their quality is also more guaranteed. Moreover, in terms of price, the new picks have not become expensive because of their high quality.

Types of carbide coal teeth picks

There are many types of coal picks. The general structure is a quenched and tempered low-alloy structural steel cutter body inlaid with a carbide tip.

The pick is subjected to high periodic compressive stress, shear stress, and impact load during operation. The main failure modes are cutter head falling off, chipping, and wear of the cutter head and cutter body. Under certain working conditions, the failure of the pick is often caused by the breakage of the cutter body.

Since the mechanical properties of the pick body directly affect the service life of the pick, a reasonable selection of the material of the pick body and an effective heat treatment method will help reduce the wear and breakage of the pick body and reduce the consumption of shearer picks. It has positive significance to improve the operation rate of coal mining machinery and increase the comprehensive economic benefits of coal mining production.
