Speed Setting and Technical Requirements of Pinch Roll for Rolling Mill
Speed Setting Requirements of Pinch Roll
The speed of pinch roll is generally more than 3 % ~ 5 % of the speed of the finishing mill and can be further increased in the case of high rolling speed, but not more than 10 %.
The speed setting of the pinch roller is inputted by the manual to the computer, and the speed calculation value of the pinch roller is calculated by the computer according to the rolling speed and the speed coefficient of the pinch roller, which is the reference value of the pinch roll speed.
The Technical Requirements for the Pinch Roll:
The setting range of the pinch roll gap is 0.2 ~ 2mm, which is adjusted according to different specifications and steel grades. The working pressure of the clamping roller cylinder is 0.2 ~ 0.35MPa, which is adjusted according to different specifications and steel grades.
The installation and centering of the pinch roller guide are more strict. The inlet guide shall be aligned with the clamping groove then clamping and fixing after it is pushed to the right position. The outlet guide and the pinch roller face remain micro gap and clamped together.
