In this paper, it is mainly analyzed and introduced the causes of internal hexagonal defect in super thick walled tube rolled with sizing mill in production of seamless steel pipe. Moreover, it is controlled by such means as increasing the rolling pass as well as reducing the reduction rate of each frame and coefficient of ovality so that the wall thickness accuracy of thick walled tube, ratio of first-grade products and yield of metal are improved.

文章主要分析介绍了无缝钢管生产中,定径机轧制特厚壁管“内六方”缺陷产生原因,并且通过增加轧制道次、减少各机架减径率及椭圆度系数的方法来控制厚壁管内六方缺陷的产生,从而改善厚壁管壁厚精度,提高成品管一级品率和金属成材率。

文章主要分析介绍了无缝钢管生产中,定径机轧制特厚壁管“内六方”缺陷产生原因,并且通过增加轧制道次、减少各机架减径率及椭圆度系数的方法来控制厚壁管内六方缺陷的产生,从而改善厚壁管壁厚精度,提高成品管一级品率和金属成材率。

厚壁管  /  内六方  /  减径率  /  成材率

In this paper, it is mainly analyzed and introduced the causes of internal hexagonal defect in super thick walled tube rolled with sizing mill in production of seamless steel pipe. Moreover, it is controlled by such means as increasing the rolling pass as well as reducing the reduction rate of each frame and coefficient of ovality so that the wall thickness accuracy of thick walled tube, ratio of first-grade products and yield of metal are improved.
