| 摘 要： | 汽车大梁钢510L由于碳含量在包晶区内,容易出现表面纵裂,本文通过控制钢中碳含量、钢水过热度,使用专用结晶器保护渣,调整结晶器冷却水流量等一系列措施,表面纵裂纹明显减少。

| Abstract: | As the content of carbon in 510L beam steel is in peritectic area,longitudinal crack usually formed on the surface of the slab.In this article,by control several factors,such as the content of carbon,Degree of Superheat,use for a special purpose mold powder,adjust flow of cooling water on mold and others,reduce the amount of longitudinal crack on the slab surface. |
