Rapid calibration method for hot-rolled coiled side guide plates

Abstract

The invention relates to a rapid calibration method for hot-rolled coiled side guide plates. The rapid calibration method comprises the following steps of: mounting displacement sensors for detecting the displacement of the side guide plates in cylinders of the two side guide plates; mounting a calibration device in a positioning hole of a roller way between the two side guide plates; pulling out telescopic rods on the two sides of the calibration device, and pressing the telescopic rods against the two side guide plates; and checking the length of the telescopic rods and transmitting measured data to a programmable logic controller (PLC). The method can be used for reducing the calibration time of the coiled side guide plates and ensuring the coiling quality.

Description

technical field [0001] The invention relates to the technical field of coiling side guide plate calibration, in particular to a quick calibration method for a hot rolling coil side guide plate. Background technique [0002] The existing hot-rolled coil side guide calibration method is to place a calibration block with a certain size on the roller table between the two side guide plates, use the side guide plates to repeatedly clamp the calibration billet, manually measure the actual data on the spot with a ruler, and then convert the data Input to the HMI screen. [0003] This method has two defects. One is that each calibration needs to be hoisted to the calibration position of the roller table and the side guide plate by a crane. The calibration time is very long, which takes about half an hour. There is not enough time to calibrate when the time is shut down, and it can only be scheduled for regular maintenance or long-term shutdown, which is inconvenient and flexible. M...

[0003] This method has two defects. One is that each calibration needs to be hoisted to the calibration position of the roller table and the side guide plate by a crane. The calibration time is very long, which takes about half an hour. There is not enough time to calibrate when the time is shut down, and it can only be scheduled for regular maintenance or long-term shutdown, which is inconvenient and flexible. Moreover, when there are calibration conditions, the use of the crane conflicts with the roll change and maintenance of the rolling line, which will affect It is often impossible to carry out other maintenance items; the second is that the operator has to repeatedly measure up and down the roller table when performing calibration, which not only has a heavy workload, but also has certain potential safety hazards
