摘　　要：通过实测轧件周长，对目前采用的轧辊工作直径计算方法进行了校正，并探讨了孔型不均匀磨损对荒管壁厚精度和生产过程的影响；提出了提高壁厚精度和延长孔型使用寿命的设想。Based on the measurement of the rolled piece perimeter,correction was made to the method for calculation of the working diameter of the roll.An investigation on the influence by the uneven wear of the roll groove on the tube W.T.accuracy and the pipe manufacturing course is made,based on which measures for improving the W.T.accuracy and the groove service life are proposed.
