Abstract：

In order to improve the accuracy and efficiency of rolling groove calibration and groove adjustment for vertical nine-high rolling mill，improve the shape and dimension accuracy of rolling blank, and reduce the production cost, the rolling groove calibration principle was researched, the positional relationship of rolls between the two states for groove calibration and end moment of rolling was established, and the method of groove calibration was proposed. Then, the movement law of roll during the rolling process was studied, and by decomposing the circular oscillating motion of web roll into the movements of wheel along the axis and radial directions, the displacement parameters of web roll along the axis and radial directions for wheel during the rolling was researched respectively to propose the groove adjustment method. Furthermore, the special tool for measuring the relative spatial position of rolls was designed to assist the groove calibration and groove adjustment. The results of production show that the rolling groove calibration and groove adjustment method can improve the shape and dimension accuracy of rolling blank for wheel, and at the same time improve the efficiency of groove calibration and groove adjustment.
