摘要: 分析在熱軋低碳含錳鋼板上觀察到的表面帶狀組織,討論了帶狀組織形成的原因和預防方法.實驗測定了厚度為8mm與5mm熱軋鋼板冷彎時表面的局部相對伸長,通過實驗結果說明表面帶狀組織是導致鋼板出現冷彎裂紋的主要原因之一.提出了防止帶狀組織生成、避免冷彎裂紋的方法要點.

Abstract: Superficial banded structure was observed on hot strips of low carbon steel. The formation mechanism of the banded structure was discussed and some measures were proposed to minimize the superficial flows. Experiments were carried out on the surface local elongation of cold bending specimens with 8 mm and 5 mm in thickness respectively. The results indicated that the bending flaws of thick strips arise mainly from the existing of the superficial banded structure.
