Technical Field

The invention relates to the technical field of mining equipment, in particular to a mining cutting pick.

Background

The cutting teeth are divided into cutting teeth of a coal mining machine and cutting teeth of a heading machine, are parts on the heading machine, have higher requirements on hardness, contain graphite impurities, have uneven grain distribution, more pores and uneven tissues, and are the main reasons for abrasion of the hard alloy head, and the content of alloy elements in the alloy does not meet the requirements; the quality performance of the tooth body material is unstable, and improper control of the heat treatment process is the reason for abrasion of the tooth body.
