    Resurfacing Welding Repair for Pinch Roll of the Hot-rolled Plate Coiler

      摘要
    • 摘要: 依据热轧板带厂夹送辊的使用工况,选择了YJ254-S和YJ245-S两种药芯焊丝,用自动埋弧堆焊工艺对夹送辊进行堆焊修复,对两者的组织和性能进行了对比,并在实际生产中作了应用.结果表明:YJ245-S焊丝的性能优于YJ254-S的;YJ254-S堆焊后的上下夹送辊使用寿命为1 a,而YJ245-S堆焊后的使用寿命是YJ254-S的1.2～1.5倍.

       

      Abstract: According to the service condition,pinch rolls of the hot-rolled plate coiler were repaired by submerged-arc surfacing welding process with YJ254-S and YJ245-S as flux-cored wires separately.Microstructure,properties and practical application effects were compared.The results show that the properties of YJ245-S are better than those of YJ254-S.Service life of the pinch roll repaired with YJ254-S is about 1 year.However,the service life of the pinch roll repaired with YJ245-S is 1.5-2 times of the former.
