WCB闸阀阀体拉伸性能不合格原因分析
发布时间：2019-04-04 13:08
【摘要】：采用化学成分分析、金相检验、断口、扫描电镜及能谱分析等方法对WCB闸阀阀体拉伸性能不合格的原因进行了分析。结果表明,阀体中碳含量偏低、残余铸态组织、非金属夹杂物及显微疏松是导致WCB闸阀阀体拉伸性能不合格的原因。
[Abstract]:The reasons for the unqualified tensile properties of WCB gate valve body were analyzed by means of chemical composition analysis, metallographic examination, fracture surface, scanning electron microscope and energy spectrum analysis. The results show that the low carbon content in the valve body, residual as-cast structure, non-metallic inclusions and micro-looseness are the reasons for the unqualified tensile properties of the WCB gate valve body.
