结果表明,断坯截面存在对称分布的粗晶区和细晶区,铸坯产生断裂的原因是连铸坯浇铸完毕后二冷水喷水量不均匀并且未采取缓冷措施,使铸坯形成了脆性组织上贝氏体,在铸坯的转移过程中,内应力导致脆性组织产生裂纹。
The results show that slow cooling after rolling can prevent the crack caused by hydrogen.
针对热轧棒材的低倍中心裂纹问题,本文通过对热轧结构钢的数据统计和金相断口分析,阐明了低倍中心裂纹的特征和断裂机理, 确定了该缺陷的性质为氢致白点,并通过试验验证了轧后冷却对该缺陷的影响,得出了通过采取适当的缓冷措施可以避免氢致裂纹产生的结论。
