摘要
薄壁钢管在各行业中的应用非常广泛。在生产薄壁钢管时遇到的一个共性问题是成型鼓包。引起鼓包最根本的原因是带钢边缘延伸超出了该材料的弹性极限范围。从变形原理入手,分析了产生鼓包的原因,着重从原料、工艺布局和轧辊孔型设计等方面提出了解决鼓包的一些方法。
Light-wall steel tubes are widely used in many fields. A common problem as encountered with in manufacturing of such tubes is bulging of the material during formation process. The root cause of this undesirable phenomenon is that the extension of the strip edge area is out of the elasticity limit of the material. In the paper the cause for the said bulging is analyzed with the deformation theory. Also proposed are certain solutions for the problem, involving the material, process arrangement and roll groove design, etc.
