出口法兰型钢轧辊焊接修复工艺研究

Study on the Repair Welding Technology In Shaped Roll for Outlet Flange

出口法兰型钢轧辊在使用过程中易出现裂纹等缺陷.本文就出现裂纹的轧辊焊接修复提出了分区、分段、短道和由中心向外围辐射的焊接工艺,且焊后锤击,可使修复区的内应力始终处于非拘束状态,同时分析了此种修复焊接工艺的特点.

The crack appears frequently in using the shaped roll for outlet flange. A kind of repair welding technology is advanced in this paper, which is welded from center to edge and in multi-layer and multi-short-pass. The weld bead is hammered. Then the internal stress of the repaired area is in non-restrain state all along. The characteristics of this repair welding technology is analysied.
