摘要
滚拔减径是无缝钢管生产的一项新技术,与常规固定模空拔相比,从根本上改变了变形区中的摩擦条件,速度条件和变形条件,从而改善了金属变形的不均匀性,减小了金属与模具间的摩擦,致使拔后钢管内的残余应力明显降低。该工艺还可以降低能耗、简化生产工艺、省略润滑工序等。
Reducing tube through roller dies is a new technique in seamless tube production. Compared with conventional die drawing method, the friction, velocity and deformation condition in deformation region have changed essentially. Nonuniform deformation and friction between metal and tool has been improved, therefore residual stress is reduced. This new technique decreases power consumption, makes procedure simplified and omits lubricating process.
