仿型轧制工艺是一种先进的金属少无切削成形工艺。能否用它来轧制大型的重要零件——机车车辆用车轴,曾一度在国内引起争论。本文通过试验结果和国外的生产实践从技术经济效益、质量指标和运行试验结果等方面,论证了在大型 S220型仿型轧机上轧制车轴的可行性。 Imitation rolling process is an advanced metal less no cutting forming process. Can it be used to roll large important parts - locomotive axles, once caused controversy in the country. In this paper, the feasibility of rolling axles on a large S220 profiled mill is demonstrated from the test results and overseas production practices from the aspects of technical and economic benefits, quality indicators and operation test results.
