Research on Laser Measurement Technology for Online Roll Profile Measurement in Strip Rolling Mills
Source abstract
Abstract
Online roll profile measurement technology enables real-time acquisition of the roll profile, guiding optimised roll change intervals to enhance production efficiency and product quality. To improve the accuracy of online roll profile measurement, this paper conducted research on laser measurement technology for online roll profile measurement in strip rolling mills. The factors influencing sensor measurement errors were analysed, and a protective housing for the sensor was designed. The experimental results showed that after installing this protective housing, the temperature fluctuation around the sensor was less than 0.2 °C, and the measurement error in a water environment was less than ±5 μm. The straightness error compensation model of the measurement system was established, and online roll profile measurement experiments were conducted on a four-high rolling mill in the laboratory. The experimental results indicated that the measured roll profile closely matched the actual roll profile, with a measurement error of less than 6.3 μm. This paper offers a novel approach to the study of online roll profile measurement technology.
