本文讨论了铸态珠光体球铁曲轴的生产技术及其生产可行性。作者在实际生产条件下通过向稀土镁球铁中加入微量元素Cu、Sn、Sb、Al、Ti并改变它们的含量研制出铸态珠光体球铁,使铸态性能达到QT60-2。并研究了合金加入量、孕育剂、孕育处理方法等工艺因素对珠光体数量及性能的影响,并获得了较好的技术经济效益。 This paper discusses the production technology of as-cast pearlite ductile iron crankshaft and its production feasibility. Under actual production conditions, the authors developed as-cast pearlite ductile iron by adding trace elements Cu, Sn, Sb, Al, Ti and changing their content in rare earth ductile iron so as to achieve the as-cast performance of QT60-2. The effects of technological factors such as alloy addition amount, inoculant and inoculation method on the amount and properties of pearlite were studied, and the technical and economic benefits were obtained.
