| 摘 要： | 42CrMoA钢(%:0.34~0.49C,0.9~1.2Cr,0.15~0.25Mo)内燃机曲轴成品约重1t,用锻造生产其毛坯重6.2t,采用电渣熔铸-电渣熔焊法生产的坯重仅为1.5t。42CrMoA钢电渣熔铸件化学成分均匀,纯净度较锻件高。在8240柴油机上装车使用结果表明,与锻钢曲轴相比,没有观察到表面磨损脱落,较好地解决了曲轴的磨损脱落问题。

| Abstract: | The weight of one crankshaft finished product of steel 42CrMoA (0.34～0.49C,0.9～1.2Cr,0.15~ 0.25Mo) for diesel engine is about 1 t, for which the weight of forging blank is 6.2 t, while the weight of electroslag remelting(ESR)casting - welding blank in only 1.5 t.The chemical composition of steel 42CrMoA ESR casting blank is uniform, of which the cleanliness is high than that of forging blank. The results in service at 8240 diesel engine showed that as compared with forging crankshafts, there was no wear abrasion scaling observed to better resolve the problem about wear abrasion scaling off. |
