Embodiment Construction
[0012] The invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0013] refer to figure 1 , a method for correcting roll bending on-line, comprising the steps of:
[0014] In the first step, by viewing the counterweight display screen on the calender operation touch screen in due course, you can clearly see the range of the calender counterweight pressure change when the roller 5 rotates one revolution, and record the maximum and minimum values. If the difference between the maximum and minimum values If the value exceeds 40Kg, it indicates that there is bending deformation in the roller 5,
[0015] The second step is to mark the water outlet position of the roller 5, mark the water outlet of the 1# water chamber as the first water outlet 1, mark the water outlet of the 2# water chamber as the second water outlet 2, and mark the water outlet of the 3# water chamber Mark the water outlet as the third outlet 3, mark the wa...

The invention provides a method for online bending correcting of a roller. The method comprises the steps of firstly confirming the maximum value and minimum value of the counterweight pressure value of a calender after the roller revolves a circle and determining the bending of the roller through the jumping of a counterweight pressure rod, then marking in the water outlet position of the roller, determining the position of the roller corresponding to the counterweight pressure rod when the counterweight pressure reaches the maximum value and noting down the number of the position, marking the area, properly shutting down the corresponding water outlet to observe the change of the counterweight pressure till the counterweight pressure rod is within the range of normal production, and completing the correction of the roller. According to the invention, the bending of the calendering roller can be directly determined from the change of the counterweight pressure of the calender rather than be determined when the thickness of the product is beyond specification, and the adjustment time is short.
Description
technical field [0001] The invention relates to the technical field of roller correction in rolling glass production, in particular to an online method for correcting the bending of rollers. Background technique [0002] Due to the processing accuracy of the calendering roller, the axial runout of ±0.1mm, and the thermal deformation during the pressing process, the calendering roller often fails to meet the required size requirements during the production process. The general calendering glass specification is 3.2±0.2mm, Thickness difference ≤ 0.25mm. Generally, the online calibration of calender rolls is based on the size of the calendered product, corresponding to the traction ratio of the calender rolls and the circumference of the calender rolls, adjusting the water output in the corresponding area of the roll, changing the temperature of the local area of the roll, and according to the thermal expansion and contraction The principle is to compensate the local defor...
