针对热轧不锈钢复合板生产过程中产生气泡的问题，对不同生产工艺生产、超声波检测正常及异常的钢板取样进行金相分析，结果表明，开轧温度高、压缩比大的复合板结合面孔洞少，气泡产生与隔离剂烘干时间、复合坯真空度、轧制温度、压缩比有关。采取提高真空度、保证复合坯加热均匀和增加压缩比等措施，基本消除了用基准灵敏度超声可检测出的气泡。

In view of the bubble problem in hot-rolled stainless steel composite plate, normal plates in ultrasonic test and abnormal plates in ultrasonic test produced by different processes were sampled for metallographic analysis. The results showed that the combined surface of the composite plate produced with high start rolling temperature and large compression ratio has few bubbles. The bubbles are associated with isolating agent drying time and the vacuum degree, rolling temperature and compression ratio of composite billet. By increasing the vacuum degree and compression ratio and ensuring the composite billet heating uniformity, the bubbles can be detected by benchmark sensitivity ultrasound were basically eliminated.
