⼀、热处理⼯艺流程

Flowandflowchartofheattreatmenttechnics

原料钢管由车间起重机吊运⾄热处理线上料台架上，⼈⼯打开捆带后将钢管平铺在上料台架上，后由拨料器逐根将钢管拨⼊辊

道，辊道将钢管纵向送⾄淬⽕炉辊道。送料辊道与⼊炉辊道均为倾斜布置，以便使钢管边纵向前进边旋转。淬⽕炉为纵进纵出

步进式加热炉。

钢管进⼊淬⽕炉后，根据钢管的热处理⼯艺制度的要求，在炉⼦内边步进边加热，直⾄步进⾄炉⼦尾部出料辊道，炉⼦出料辊

道将钢管边旋转纵向输送⾄输出辊道。

当钢管需要进⾏淬⽕时，淬⽕装置前的移钢机逐根将钢管移送⾄⽔淬装置。⽔淬装置采⽤内喷外淋、压轮压住旋转淬⽕⽅式，

根据⽔淬⼯艺，分别控制⽔淬装置内喷、外淋⽔量和冷却时间，以实现对钢管最终组织和性能的控制。随后，钢管横向移送⾄

⽔淬装置后台架，进⾏空⽔，空⽔后钢管拨⼊回⽕炉⼊炉辊道，纵向输送，进⼊回⽕炉。

当钢管需要进⾏正⽕处理时，由出炉辊道将钢管逐根运⾄正⽕链式冷床输送辊道处，上料机构逐根将钢管移送⾄正⽕冷床上，

进⾏冷却、收集。如钢管需要正⽕+回⽕，由翻钢板将钢管到放⾄冷床输出辊道，后由辊道运送⾄回⽕炉进⾏回⽕处理。

回⽕炉为纵进纵出步进式加热炉，钢管⼊炉后，根据钢管的热处理⼯艺制度要求，在炉⼦内边步进边加热，直⾄步进⾄炉⼦尾

对于温矫的钢管，要求矫直温度400℃左右，此时冷床以较合适的速度快速将钢管移送⾄矫直机前，以控制和保证矫直温度。

经矫直后的钢管进⼊其后的冷床，对于温矫后的钢管实现均匀的冷却，通过冷床进⾏后部的⼈⼯检查⼯序。随后，钢管进⼊吸

灰装置⼯位，将钢管内部的氧化铁⽪等杂质清理⼲净，收集⼊库。
