Spark Recognition-Based Hot-Rolled Coiling Side Guide Plate Control Method
20220402008 · 2022-12-22 ·

The present invention discloses a control method of hot mill coiler side guides based on spark recognition, where the side guides are adjusted according to the width of sparks from the friction between the hot rolled strip (20) and the side guides (11). An industrial camera (9) is provided obliquely above the side guides (11), and a detection system implements a real-time analysis on the images taken by the industrial camera and determines the magnitude of sparks generated on either side of the side guides according to the spark width. For each unilateral side guide, it is adjusted according to the spark width M.sub.S corresponding to that side guide (11). For said unilateral side guide (11), the deviation of the single-side spark width ΔM.sub.S is obtained according to ΔM.sub.S=M.sub.S−M.sub.aim. The position adjustment magnitude ΔW.sub.S of the unilateral side guide (11) can be obtained according to formula (I). And the pressure adjustment magnitude ΔP.sub.S of the unilateral side guide (11) can be obtained according to formula (II). This method allows the hot rolled strip (20) always in the relative center of the steel coil, reduces the wear of the side guides (11), avoids various defects of the steel coil, and makes the steel coil in good shape.
