| 摘 要： | 通过局部感应加热进行无缝钢管推进制热扩是生产大口径薄壁无缝管的有效方法。但对于较高的钢级,须进行随后的炉内加热热处理才能保证其良好的综合机械性能,而大口径薄壁管的热处理极易使钢管弯曲变形,无法校直。文章介绍了衡钢集团鸿大公司通过局部感应加热热扩开发生产406.4 mm×7.92 mm,X60管线用无缝钢管的过程,制定合理的工艺既保证外观尺寸符合API5L(44)要求,又使其综合性能达到PSL2水平。

| Abstract: | The propulsion system hot expansion through the partial induction heating is a effective method of producing large-diameter thin-walled seamless tube.For higher level of steel,the following furnace heating can guarantee the comprehensive mechanical properties.The heat treatment of large-diameter thin-walled seamless makes the tube deform easily,it can not be straightened.This paper deals with the process,which not only guarantee the dimensional measures comfort to API5L(44),but also comprehensive performance achieved PSL2 level,of the production line pipe 406.4×7.92mm,X60 through partial induction heating hot expanding in Hongda Special Steel Tube Co.,Ltd. |
