摘要
对低碳贝氏体高强钢生产中出现的星形裂纹进行了研究,阐述了引起裂纹的主要因素,并提出了改进措施,使得高强钢裂纹改判率大幅下降。
This paper studied the reasons for star crack in low carbon bainite high strength steel, expounded the main factors resulting in crack. On that basis the relative countermeasures were put forward, which significantly decreased the star cracking ratio of high strength steel plate.
