Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to a measuring ruler for the central surface of a rolling mill arch. Background Art

[0002] At present, when using the rolling mill production line to produce and process metal sheets, the arch alignment is measured by hanging wires. The angle steel is fixed on the bottom plates on both sides of the arch, and the hanging wire is made at the midpoint of the angle steel. Then the distance between the midpoint and the side of the arch is measured with a ruler, thereby judging whether the moving blocks on the operating side and the transmission side of the mill arch are on the same plane, and judging whether the rollers are aligned with the center of the mill rollers during operation, and whether there is an angle deviation. However, when using a ruler to measure the hanging wire, there is a certain amount of skewness of the ruler, resulting in a large deviation between the measured value and the theoretical value, and the measurement accuracy is not high, so that the measured value does not play a good guiding role in controlling and revising the mill alignment. In order to solve this problem, it is necessary to use more convenient and effective measuring tools. Utility Model Content
