采用SEM、EDS和XRD对不同加热温度下W470连铸坯氧化铁皮的微观形貌及相结构进行研究。结果表明,W470氧化铁皮难以除去的原因是氧化铁皮熔化,液相包裹着FeO,凝固时发生共晶反应,生成FeO/Fe2SiO4共晶混合物,并深嵌入基体。降低加热炉的加热温度,使连铸坯全程在FeO/Fe2SiO4共晶混合物熔点(1177℃)以下加热,可降低氧化铁皮与基体的结合力,能够有效解决W470除鳞困难问题。 The microstructure and phase structure of iron scale of W470 continuous casting billet at different heating temperatures were investigated by SEM,EDS,and XRD.The results show that the reason why the iron scale of W470 removes hardly is that iron scale is melted and the FeO is surrounded by the liquid phase,which forms FeO / Fe2SiO4eutectic mixture and is embedded into the matrix after solidification.Lowering the heating temperature and keeping the continuous casting billet heating under the melt...
