Background

The cutting pick is a direct cutting tool of a coal mining machine and a heading machine, has very bad working conditions, is subjected to the friction and impact action of a coal bed or rock in the using process, generally has short service life, and has a main failure mode that an alloy head falls off or a tooth body has poor bending resistance and is bent or broken under the action of strong force because the tooth body at the head part of the cutting pick is abraded too fast.

The heat treatment refers to a metal hot working process for obtaining expected structure and performance by means of heating, heat preservation and cooling of materials in a solid state, and the heat treatment is an important processing procedure in the cutting pick processing process.

The requirements for cutting picks in mining operations are: the pick head, in addition to holding the carbide and preventing it from falling off, also has a high hardness to resist wear from coal seams, dirt bands or rocks. Therefore, the tooth shank has enough impact toughness in the tooth sleeve (or tooth seat) hole besides rotation. This requires that the pick head has higher wear resistance than the shank of the pick body, and is therefore particularly important for the location of heat treatment, where manual pick transport for heat treatment is often inefficient, and where automated equipment is difficult to adapt to the heat treatment requirements of picks of various specifications.
