根据典型的钢板裂纹实例，通过对铸坯、钢板试样进行研究，用对比分析的方法得出低 Ti/ N 比导致板坯热送轧制钢板产生表面裂纹的结论。并据此采取一系列措施，取得了良好的效果。
根據典型的鋼闆裂紋實例，通過對鑄坯、鋼闆試樣進行研究，用對比分析的方法得齣低 Ti/ N 比導緻闆坯熱送軋製鋼闆產生錶麵裂紋的結論。併據此採取一繫列措施，取得瞭良好的效果。

Based on the instance of typical surface cracks of AH32 grade hull plate,Jigang arrives at a conclusion that low Ti/ N ratio is the cause of surface cracks on hull plate rolled from hot charged slab by utilizing comparison anal-ysis method. After taking a series of assurance measures from the aspects of LF refining,continuous casting and slab re-heating processes,Jigang significantly improves the surface cracks of AH32 hull plate.
