Problems solved by technology

[0003] Nowadays, part of the equipment used is to monitor the strip quality online by manual online measurement data, and the other part achieves simple automatic control, using X-ray single-line diagonal measurement method to detect the physical properties of the strip, but this method does not affect the control of the pattern. They all start from the measurement point and finally connect multiple points into a line to approximate the judgment of the version

example 1

[0027] Example 1: The thickness of the test strip is between 27-29μm. Such as image 3 As shown, curve 1 is the measured data of the present invention, and curve 2 is the actual measured data. The strip thickness measured by the present invention is consistent with the actually measured strip thickness.

[0028] It should be noted that the characterization of strip properties is determined by physical parameters and magnetic performance parameters. Different characterizations of the same object will have specific and interrelated characterizations when they approach the true value. The invention obtains the real-time profile of the strip by combining the profile lines at a unit time point into a profile surface. Through the real-time monitoring of the shape of the strip, combined with the analysis of the magnetic performance results, the physical parameters affecting the magnetic properties of the strip are obtained, and finally the annealing time before the strip leaves the...

Abstract

The invention relates to a method and a device for measuring plate cut of belt material. The method includes: an upper laser sensor measures a first distance signal; a lower laser sensor measures a second distance signal; a programmable logic controller (PLC) receives the first distance signal and the second distance signal and carries out relevant calculation to obtain the thickness of the belt material; and finally by a personal computer (PC), thickness data in the unit time is combined to display the plate cut of the belt material. By utilization of a laser beam of which the top and the bottom are collimated and collinear, the belt material to be measured is irradiated, two measurement points are formed on the surface of the belt material, and by obtaining of the distance between the two measurement points, the real-time plate cut and physical parameters are obtained in the process of spraying. Compared with the prior art, the method and the device for measuring the plate cut of the belt material has the advantages of being easy to operate, low in cost, high in measurement accuracy and the like, and meanwhile provides a monitoring method for stable and mass production of the high-performance belt material.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a method and a device for online measurement of strip shape. Background technique [0002] Shape is an important quality indicator of non-ferrous metals and steel plate and strip products. There are generally two types of shape detection methods: static measurement and dynamic measurement, and the shape control of strips can only be carried out when dynamic detection is realized. [0003] Nowadays, part of the equipment used is to monitor the strip quality online by manual online measurement data, and the other part achieves simple automatic control, using X-ray single-line diagonal measurement method to detect the physical properties of the strip, but this method does not affect the control of the pattern. They all start from the measurement point and finally connect multiple points into a line to approximate the pattern. Contents of the invention [0004] The purpose of ...
