本文研究了用稀土合金处理的铸铁。在研究这种铸铁的某些液态参数时,对铁水凝固过程进行了热分析。此外,还研究了铸铁结晶时蠕虫状石墨的形核与生长以及石墨包含物的形态。用中央工艺与机械制造科学研究所设计的“抛物面”型装置,对在高纯度氩气氛中的铁水静滴进行 X 射线摄影,测定了表面张力σж—г与相间张力。为了分别测定铁水与 This paper studies cast iron treated with rare earth alloys. In studying some of the liquid parameters of this cast iron, the hot metal solidification process was analyzed. In addition, the morphology and morphology of vermicular graphite during cast iron crystallization and the morphology of graphite inclusions were investigated. Using the “parabolic” type device designed by the Central Processing and Mechanical Manufacturing Research Institute, X-ray photography of the molten iron in a high-purity argon atmosphere was carried out. The surface tension and the interlaminar tension were measured. In order to determine the hot metal and iron respectively
