Abstract
Description
technical field
[0001] The invention relates to a continuous precision measuring instrument for cold-rolled sheet thickness, which is mainly used in the continuous and accurate measurement test of cold-rolled sheet thickness in a physical and chemical laboratory, and belongs to the technical field of cold-rolled sheet measuring instruments. Background technique
[0002] With the advancement of cold-rolling technology, smooth surface and small thickness difference of the same plate have become the minimum requirements for users of cold-rolled products. At present, in cold rolling production, the thickness measurement and control methods in the width direction of the plate include online and offline methods. Among them, the methods of online thickness measurement mainly include ray method, ultrasonic method, laser method, etc.; offline measurement mainly adopts after sampling. Measured manually off-line using a screw micrometer. Most of the cold-rolling production lines have ...
