通过实地调查、理化检测和断裂曲轴分析发现,在球铁曲轴的生产各环节中,必须充分重视并合理开展理化检测工作,尤其应注重圆角处的质量,避免“凭经验生产”;许多曲轴的失效,与理化检测工作开展得不合理有关,加强和完善理化检测体系,在生产过程中合理有效地开展理化检测工作,对提高球铁曲轴的质量具有重要意义。
Through the field investigation, physical and chemical detection and fracture crankshaft analysis, we found that all aspects of the production of the ductile iron crankshaft must be fully valued and rationally carried out physical and chemical testing, with particular emphasis on the quality of the fillet, to avoid “production by experience”; many crankshaft Of failure, physical and chemical testing carried out unreasonable related to strengthen and improve the physical and chemical testing system, in the production process to carry out reasonable and effective physical and chemical testing work to improve the quality of the ductile iron cilium is of great significance.
