为解决含硼钢种连铸角裂问题，对含硼钢种连铸角裂的原因进行了分析。通过采用高碱度保护渣、弱冷的二冷配水、减小二冷水喷嘴角度以及静态辊缝措施后，含硼钢种连铸角裂问题得到有效控制。
為解決含硼鋼種連鑄角裂問題，對含硼鋼種連鑄角裂的原因進行瞭分析。通過採用高堿度保護渣、弱冷的二冷配水、減小二冷水噴嘴角度以及靜態輥縫措施後，含硼鋼種連鑄角裂問題得到有效控製。

In order to solve the problem of corner cracks on continuous casting slabs of boron-bearing steel grades, the causes leading to the cracks are analyzed. By taking such measures as using casting slag powder with high basicity, carrying weak secondary cooling water distribution, reducing the angle of the jet nozzle for secondary cooling water and adopting the static roll gap, the problem of the corner cracks is under effective control.
