| 摘 要： | 为了查明钢板表面裂纹产生的原因和产生机理,利用实验室加热炉对加热前和加热后产生的两种条件下的表面裂纹进行了模拟。试验结果表明,裂纹附近组织中脱碳层和氧化物圆点的出现是判断裂纹产生时间的必要条件,裂纹附近的脱碳层和氧化物圆点是轧制前坯料表面裂纹的基本特征,利用此特征查找裂纹产生的原因具有重要的指导意义。

| Abstract: | Abstract： In order to investigate the reason and mechanism of surface crack produced, two cracks producing conditions before heating and after heating were simulated in the laboratory by means of a heating furnace. The experimental results showed that the decarburized layer and the oxide dots around cracks are the essential condition of judging the crack producing time. The decarburized layer and the oxide dots around cracks are basic feature of slab surface cracks during high temperature heating for long time. It is an important guiding significance to decide the causes of cracks according to this feature. |
