Detailed Description

The invention is further described below with reference to the following examples:

a calibration method for a side guide plate of a finishing mill is characterized by comprising the following steps: the equipment to be related by the calibration method comprises an organic housing memorial archway 1, an inlet upper guide 2, an inlet lower guide 3, a side guide plate A5 at one operation side and a side guide plate B7 at one transmission side, and the calibration method comprises the following steps:

the first step is as follows: the side guide plate A5 and the side guide plate B7 are arranged on the slideway 4, and a beam 6 is arranged in the middle;

the second step is that: before calibration, the slide ways of the side guide plate A5 and the side guide plate B7 are checked for the existence of foreign matters;

the third step: opening a certain opening degree at two sides of the side guide plate A5 and the side guide plate B7 at the same time, and manually closing and opening the side guide plate A5 and the side guide plate B7 to test whether the actions are flexible or not;

the fourth step: it is detected whether there is a mechanical jam on the slideway 4.

As shown in the figure, the calibration method needs three persons to cooperate, two persons are in the machine frame, and one person is used for calibration on an HMI picture of the operation table.

And (3) starting a calibration mode by an operator on the operating platform, closing the side guide plate A5 and the side guide plate B7 to the minimum position, actually closing the two sides of the side guide plate A5 and the side guide plate B7 to the minimum position on site when the site is observed, and simultaneously displaying the opening degree values of the side guide plate A5 and the side guide plate B7 to be unchanged by the HMI picture. Personnel in the mill stand begin to measure the distance of the opening degree L1 of the side guide plate; the distances L2, L3 from the operating side and drive side housing windows to the insides of the lining panels of side guide A5 and side guide B7 need to be measured at the same time. When the actual measurement results show that the lengths L2 and L3 from the operating side and the transmission side to the memorial archways are inconsistent and the difference L is larger than 5mm, the alignment needs to be calibrated. Due to the fact that the side guide plates are not centered, when the measurement result L2 is less than L3, the specific calculation method is that the actual opening degree of the operation side is equal to L1/2+ (L2-L3)/2, and the transmission side opening degree is L1/2- (L2-L3)/2. After the computer is completed, the calculation results of the operation side and the transmission side are input into a box corresponding to a first-level picture of the HMI of the computer, then an activation key is clicked, and after activation, the click calibration is finished.

After calibration is finished, the side guide plates are randomly opened to a certain opening degree, the distances from the operation side and the transmission side to the memorial archways are measured, the calibration is qualified if the difference is less than 5mm, and if the measurement deviation is more than 5mm after calibration, the calibration is carried out again according to the method until the calibration is qualified. The rolling mill working roll is preferably pulled out during measurement and is measured in the frame. Meanwhile, when the side guide plate is minimum, two sides of the side guide plate A5 and two sides of the side guide plate B7 are required to be in close contact with the middle cross beam, if one side of the side guide plate does not lean against the upper side, whether the side guide plate is blocked or not is searched, whether foreign matters exist on the slide way of the side guide plate or not influences the slide of the side guide plate on the slide way 4 or not is searched. When the side guide plate of the rolling mill is calibrated, the side guide plate is easy to be blocked by the guide, so that the upper inlet guard plate 2 and the lower inlet guard plate 3 are proposed to be driven to a rolling position for calibration and measurement.

The invention is measured and calculated through the corresponding side guide plate centering degree, and inputs a proper opening degree correction value in an HMI picture. The centering precision of the side guide plate can be greatly improved, and the rolling stability is also obviously improved. The problem of the broken accident of the tail drift rolling of the steel clip or the strip steel due to the large deviation of the opening and the centering degree of the side guide plate is solved, the production accident is avoided, and the stable production of the production line is ensured.

The method is mainly applied to calibration of the opening degree and the centering degree of the side guide plate of the finishing mill in the hot continuous rolling mill set, the problem of large deviation of the opening degree and the centering degree of the side guide plate can be solved by measuring different positions of the side guide plate and processing related data later, so that the positioning precision and the rolling stability of the side guide plate are ensured, and the accident rate of a production line is reduced. The method is simple, easy to operate and has good popularization prospect.
