The cutting pick and cutter need to bear huge compressive stress, shear force and impact load in the working process. Weir cutting pick heat treatment is very advanced, we use vacuum furnace heating, so that the brazed cutting pick without air cooling directly quenching. Brazing and heat treatment are completed at one time, thus improving the performance of the pick and reducing the loss.
Weir mining teeth, its wear-resistant layer is a composite coating of alloy. The alloy ceramic powder contains alumina trihydrate and ceramic powder, etc., which can effectively prevent sparks from being generated during operation. It is suitable for use in high gas environments.
The wear-resistant layer of the mining teeth is made by embedding the deep melting process, which contains two layers of hard alloy rings with a hardness of HV1750. The wear-resistant layer is tough and durable on the outside and strong and wear-resistant on the inside, with a high toughness and wear resistance, equivalent to 2-5 times the same model.
