The surface transverse cracks on AISI304 strip produced by twin-roll strip casting were studied using optical microscopic observation and colored metallographic analysis,with consideration of the near rapid solidification characteristics of strip casting.
采用化学侵蚀和彩色金相等手段,对双辊薄带连铸304不锈钢铸带表面横裂纹的成因进行了研究,并结合双辊薄带连铸亚快速凝固的特点,对薄带表面横裂纹形成的原因进行了综合分析后认为,铸带表面横裂纹均为凝固时产生的高温热裂纹,熔池的液面波动、冷钢和铸辊的表面缺陷等因素导致的铸带表层凝固速度不一致是产生表面横裂纹的根本原因,而在随后的冷却和卷曲过程中,铸带受到各种形式的拉应力则是表面横裂纹得以扩展和加深的主要原因。
