Coal pick

Mining pick is one of the vulnerable parts in mining and roadway driving machinery, and is the main tool for dropping and crushing coal. From the actual use of imported and domestic picks in some domestic coal mines, the cutter body material is mostly 42CrMo, 35CrMnSi and other steel grades, and there are also coal mines using the newly developed Si-Mn-Mo quasi-bainite steel in China. The coal industry production standard stipulates that the hardness of the cutter body is 40 ~ 45HRC, and the impact toughness is not less than 49J/cm2. In the production process, the material of the cutter body should reach or exceed the mechanical properties specified by the requirements through heat treatment.

Mining pick is one of the vulnerable parts in mining and roadway driving machinery, is the main tool of coal dropping and crushing coal, its performance directly affects the production capacity of mining machinery, power consumption, work stability and other related parts of the service life.

There are many kinds of picks, the general structure is in the quenching, tempering treatment of low alloy structure steel knife body inlaid with carbide cutter head. The cutter is subjected to high cyclic compressive stress, shear stress and impact load during operation.
