Abstract

The invention belongs to the technical field of hot rolling technologies, and discloses a method for fast obtaining the strip steel sickle bend size. The method comprises the steps that the distance L1 between two measuring points of strip steel, the distance L2 between the two measuring points in the length direction of the strip steel, and the offset value h from the center line of the strip steel are obtained; a calculation model of the strip steel sickle bend size H, the distance L1 between the two measuring points, the distance L2 between the two measuring points in the length direction of the strip steel, the offset value h from the center line of the strip steel and the curvature radius R of a strip steel sickle bend is established; and a computational formula for the H is obtained according to the calculation model. The method for measuring the sickle bend size is efficient and reliable.

Description

technical field [0001] The invention relates to the technical field of hot rolling and rolling technology, in particular to a method and a device for quickly obtaining the camber size of a steel strip. Background technique [0002] The quality of camber control of hot-rolled strip directly affects the quality of the final product. If the control is not good, it will directly cause strip deviation, wave formation, and tower shape, which will increase subsequent production costs. Therefore, it is necessary for the operator to always pay attention to the actual size control of the strip camber during the rolling process, and to continuously improve the camber size by adjusting technical means such as the level value of the rolling mill. [0003] However, at present, the rolling line is usually controlled through a large amount of data analysis, and it is impossible to directly judge the actual control size of the camber, and thus it is impossible to quickly judge whether the co...
