摘　　要：采用中频感应加热的方法使链条中的某一个修接单环在淬火后得到差温回火,差温回火后的单环与其所在链条中已经热处理过的其它链环性能保持一致,而与此单环相邻链环的性能却不受影响,提高了链条的质量和工作可靠性。Differential tempering test was carried out on a repaired single link in the chain using medium frequency induction heating.After differential tempering,the functional properties of the single link keep consistent with that of other links that have already been heat treated in the chain.Properties of the adjacent links remain unaffected and the quality and reliability of the entire chain are enhanced.

关 键 词：矿用高强度圆环链 单环 感应加热 差温回火 质量及可靠性
