A method for measuring and calibrating the side guide of the front roller table of a hot continuous rolling coiler

Abstract

The invention belongs to the field of a hot continuous rolling reeling machine, and in particular relates to a preliminary roller table side guide measurement calibration method of the hot continuous rolling reeling machine. Through use of a 1000mm steel pipe, two pin shafts are welded on the same side of the steel pipe for making two holders, and the two pin shafts are 475mm distanced from two ends surfaces of the steel pipe. Two roller table transition boards are respectively selected at inlet and outlet sides of a side guide body, the roller table transition boards are symmetrically drilled with two 20mm holes, when the side guide body is replaced for ready for calibration, a side guide is beaten to 1200mm position to stop, and the made holders are respectively were inserted in the two roller table transition boards. The distance from the surface of a side guide wear-resisting plate to the end surface of a support circular tube is respectively measured by a tape measure, by addition of 500mm into the distance, a numerical value is read out, and then is inputted into a computer. According to the method, in the time of roll changing in finish rolling, the side guide body can be replaced, and the measurement calibration work can be completed.

Description

technical field [0001] The invention belongs to the field of hot continuous rolling coilers, in particular to a method for calibrating the side guide measurement of the front roller table of the hot continuous rolling coiler. Background technique [0002] The side guide of the hot rolling coiler is the key equipment of the coiler. It plays a role in clamping the steel plate during the coiling process. The accuracy of the side guide directly affects the flatness of the end surface of the steel coil. The principle of side guide action is that the side guide body is driven by a hydraulic cylinder, and the position sensor inside the hydraulic cylinder detects the position of the side guide body. The centering accuracy of the left and right side guide bodies relative to the rolling center line directly affects the flatness of the end face of the steel coil. [0003] Since the side guide body always clamps the strip steel, grooves with irregular width and length will be formed on...

AI Technical Summary

Problems solved by technology

Manually using a tape measure to measure the centering of the roller table is slow, which is likely to cause downtime, and when the measurement is inaccurate and causes a large amount of deviation, abnormalities occur when the strip is clamped (clamping on one side is too tight, and the other side is guided) The body does not touch the strip), and it is easy to cause unqualified coils
