摘要
通过对在线生产４５×２０×０．８ｍｍ半圆、矩形管的孔型设计的研究，较好地解决了该类不对称异形管孔型设计的变形形式、计算模式和用户的特殊要求（即辊缝必须在长度为２０ｍｍ的短边中间），生产出了焊缝质量好、表面光洁、端面形状规范的结构管，满足了用户的需要。
The study of the pass design of on-line product 45×20×0.8mm semi-circular and rectangular pipes solved the pass design problems of asymmetrical special pipes-deformation form, calculating model and special requisition (i.e. cleaning between rolls must be in the middle of the short side which is 20mm in length). The structure pipes which have good quality welds, bright and clean surface and normal end surface satisfy the users' requisition.
