摘要：

为了提高立式九辊轧机轧制孔型标定和孔型调整的精度和效率、提高轧制毛坯的形状尺寸精度、降低生产成本，研究了轧制孔型标定的原理，建立了孔型标定时和轧制结束瞬间两种状态之间的轧辊位置关系，提出了孔型标定的方法；研究了轧制过程中轧辊的运动规律，通过将辐板辊的圆周摆动运动分解为沿车轮轴向和径向的运动，分别研究了轧制时辐板辊沿车轮轴向和径向的位移参数，提出了孔型调整的方法；设计了可以测量轧辊相对空间位置关系的专用工具，辅助孔型标定和孔型调整。生产实践表明，提出的轧制孔型标定和孔型调整方法提高了车轮轧制毛坯的形状和尺寸精度，同时提高了孔型标定和孔型调整的效率。

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.
