摘要
介绍了承德万利钢管有限公司从德国引进的Φ89mm焊管机组张力减径孔型采用了介于传统椭圆孔型和圆孔型椭圆度计算的设计方法。此法消除了厚壁钢管内多边形和薄壁钢管挤入辊缝的缺陷。
The paper introduced the ellipticity design method of tension reduce pass of Φ89mm welded steel tube unit which imported from German by Chengde Wanli Steel Pipe Co., Ltd. The design based on ellipticity calculation methods of the traditional circular and ellipse pass. The practice shows that the defects, such as inner polygonal of thick tube and folding ear of thin tube, are eliminated.
