Analysis on the Axial Force and Torque of Blast Furnace Taphole Drill
The axial force and torque of taphole drill are analysed. It is found out that adding punch factor in the drilling process is an effective way to improve the drilling speed. The drilling speed under adding punch factor is 1.5-2.0 times on that under not adding punch.
