Background
After the hot-rolled strip is rolled by a rolling mill, the hot-rolled strip is conveyed by a run-out table and guided and positioned by side guide plates on two sides of the run-out table, so that the head and the body of the strip are corrected to a rolling central line in the process of running, and then the strip is fed into an underground coiler to be coiled into a steel coil under the clamping of an upper pinch roll and a lower pinch roll. The side guides are arranged in front of the pinch rolls and the underground coiler and function to guide and center the incoming strip. Before the plate strip enters an underground coiler, the width value of the side guide is the plate strip width plus the margin of the edge part; after the head of the plate strip enters the pinch roll, the side guides on the two sides act together, when the side guides on the two sides contact the plate strip, the pressure control system of the side guide on one side provides a constant pressure along the length direction of the plate strip, and the side guide on the other side keeps the position unchanged. In the process, the wear plate below the side guide is the part which is closest to the contact of the hot rolled plate strip and has the most direct heat conduction. The temperature of the strip steel reaching the side guide is about 500-750 ℃, the rolling time of each strip is about 2-4 minutes, and the wear-resisting plate is made of 16Mn, so that the wear resistance of the wear-resisting plate is seriously reduced by roasting at the time and the temperature, particularly the wear resistance is most prominent when the strip steel is rolled into a strip of 8-15mm, and the wear of the side guide wear-resisting plate exceeds the offline standard after one casting time is not finished. Therefore, the positions of the strip steel entering the pinch roll and the coiling machine are deviated, and the coiled steel coil has the phenomenon of tower shape or staggered layers. In severe cases, foreign matters are pressed in due to burr pressing in the plate belt after the wear-resisting plate is worn, or burrs are clamped between the lower surface of the side guide and the roller way, so that the roller way is completely charged due to overcurrent, and production accidents are caused.
