摘要
依据圆盘剪刃使用工况,选择了YJ259?S药芯焊丝作为堆焊材料,用自动埋弧堆焊工艺对圆盘剪刃进行堆焊修复。堆焊修复后的剪刃,其强度和韧性与原剪刃相当,耐磨性比母材提高了20%。修复后的圆盘剪刃在实际生产线上进行运行考核,完全可以满足圆盘剪刃的使用要求。
According to the service requirement of disc-cutting edge, YJ259-S fluxed-cored wire was selected as surfacing material. With submerged-arc surfacing process, the disc-cutting edge was repaired and strengthened. The strength and ductility of the repaired disc-cutting edge with good shape were close to that of base metal, and the wear-resistance was increased 20% than that of base metal. The experiment results after the application in production line showed that the repaired disc-cutting edge can absolutely meet the service requirement.
