【摘要】 亚包晶钢板坯在浇注时易产生表面纵裂缺陷,经过冶金工作者多年的研究和探索,关于亚包晶钢板坯纵裂的机理及影响因素已逐步明晰。本文从亚包晶钢的裂纹敏感性,表面纵裂形成及影响因素等方面进行讨论,初步阐述了亚包晶钢板坯表面纵裂形成原因及各种因素对表面纵裂的影响。更多还原

【Abstract】 The defects of longitudinal surface cracks usually occurred during the hypo-peritectic steel slabs were cast. Under the research by scientists and engineers, the formation mechanisms and causes of longitudinal surface crack were found out. In this paper, the crack sensibility,formation of longitudinal surface cracks and the effecting facters of hypo-peritectic steel were discussed.更多还原
