Abstract
Disclosed is a calibration method for roller gaps of a rolling machine. The calibration method includes: resetting a magnetic scale and a press head of an AGC (automatic gauge control) of the rolling machine, leveling the roller gaps by pressure control, checking deviation of the roller gaps on the operating side and two driving sides of the rolling machine; stopping the rolling machine, closing the roller gaps, calibrating the rolling force of the rolling machine and resetting the roller gaps when the deviation of the operating side and the two driving sides of the rolling machine is normal; checking whether the sum of rolling force of the operating side and the driving sides of the rolling machine is smaller than the calibrated rolling force or not after the roller gaps are reset, checking whether the deviation of the rolling force of the operating side and the two driving sides of the rolling machine is normal or abnormal, leveling the roller gaps of the rolling machine again if the deviation of the rolling force is abnormal, then checking the deviation of the rolling force of the rolling machine again; resetting the roller gaps of the rolling machine and opening the same to the set value if the deviation of the rolling force is checked to be normal, thereby completing calibration.
