连铸65钢方坯的质量

Qualities of Continuously Cast Billets for 65 Steel

摘要: 对连铸150mm×150mm高碳钢铸坯凝固组织、中心偏析、夹杂物分布与类型、铸坯与轧材组织状况等进行了分析与讨论,提出了改善高碳钢中心缩孔和中心偏析的途径。

Abstract: The solidification structure, central segregation, distribution and type of inclu-sions, microstructure of billets and rolled steel for continuous cast high carbon steel billet-s(150 mm×150 mm), have been investigated and discussed. The proposal of improving the central pore and central segregations of high carbon steel billets has been made.
