铸坯火焰切角轧制后钢板出现严重的边部裂纹，对钢板边部裂纹和铸坯低倍试样进行了分析，发现低倍试样切割面存在密集的裂纹，进一步研究发现这是由于火焰切割造成的，进而推断出，铸坯火焰切角导致钢板边部严重裂纹。
鑄坯火燄切角軋製後鋼闆齣現嚴重的邊部裂紋，對鋼闆邊部裂紋和鑄坯低倍試樣進行瞭分析，髮現低倍試樣切割麵存在密集的裂紋，進一步研究髮現這是由于火燄切割造成的，進而推斷齣，鑄坯火燄切角導緻鋼闆邊部嚴重裂紋。

After cutting the edge of slab by flame, cracks occur on the edge of corresponding steel plates. And the research of slab sample shows that there are serried cracks on the flame cutting section. Further research shows it is due to the flame cutting that form the edge cracks. So it is concluded that the flame cutting on the slab edges resulted the cracks on the edge of plates.
