The hole-shaped plate can slide on the measuring rod, and the hole-shaped plate is in contact with the top of the roller.
The calibration method of the sizing/reducing mill roller only needs to replace the hole-shaped plate when calibrating the rollers with different diameters.
A method for calibrating the roller of sizing/reducing mill features that the roller of sizing/reducing mill is fixed to square frame by bolts, and can slide on measuring rod via hole-shaped plate for regulating the position of roller when it is in contact with the top of roller.
Compared with the prior art, the invention has the following beneficial effects: 1. the position of the roller is adjusted through the sliding hole type plate, the concentricity of the roller is ensured, the product quality is improved, and a method for manually adjusting the position of the roller by experience alone is eliminated. The time for adjusting the position of the roller is saved, and the accuracy is high. The condition that the product quality is unqualified due to the fact that the rollers are not concentric is effectively avoided, so that resource waste is saved, and the working efficiency is improved by saving the time for adjusting the positions of the rollers. 2. The calibration of the rollers with different diameters only needs to replace the hole-shaped plate.
