Description
Technical Field
The utility model relates to the technical field of steel rolling, in particular to a tool for measuring and calibrating a center line of a finish rolling guide ruler.
Background
In the rolling process of the hot continuous rolling strip, the centering of the guide ruler of the finish rolling rack can improve the rolling stability of the strip steel and reduce the accidents of drift, steel blocking and the like. In order to ensure the centering performance of the finish rolling guide ruler, the numerical value of the opening degree of the guide rulers on two sides is measured by taking the central point as a datum point after the central point of the guide ruler is found by measurement in a finish rolling machine. However, when the stability of the sudden rolling is poor, the center line of the guide ruler is shifted, and the center line of the guide ruler needs to be checked after the magnetic ruler is replaced due to the failure of the magnetic ruler in the rolling process, the guide ruler is centered by using the current-stage finish rolling guide ruler centering calibration method, the working rolls of the measuring rack need to be drawn out for checking the guide ruler values at two sides, which inevitably causes the excessive checking time of the guide ruler centering degree, and seriously affects the rolling efficiency.
