| Abstract: | The rapidly replaced drill rod of the hydraulic mining drilling rig is an important component of the drilling tools. Through the improvement on processing technology of the drill rod and rock drilling tests in mines, in combination with the inspection of testing products and failed samples, the material and the heat treatment technology of the rapidly replaced drill rod of the hydraulic drill rig are preliminary confirmed reasonable. In addition, improvement measures are put forward aiming at existing probl... |
