摘　　要：采用OM、SEM对国内外铸造成型的热轧无缝钢管孔型控制用导板进行组织观察,对其基体和析出相的化学成分进行了EDS分析,发现直接铸造成型工艺制备的导板无法形成典型Cr的碳化物,从而直接影响了导板的使用寿命。这说明形成典型碳化物能提高导板的使用寿命。The microstructure of hot rolled seamless tube groove controlling guide plate in domestic and foreign casting formation was observed by OM and TEM. The chemical composition of matrix and precipitate phase of the guide plate was analyzed by EDS. It is discovered that it is not able to form typical carbide of Cr in direct cast forming guide plate. Because of no typical carbide forming, the service life of the guide plate can be influenced, which shows that the service life of the guide plate improves by forming typical carbide.
