本工作采用单辊辊面为冷却介面，研究控制快速凝固带材的横向厚差的方法。
To control the lateral thick difference of rapid solidification strip, the single-roll cooling interface is applied.
采用双辊法和双带法制备的快速凝固带材，存在着较大的横向厚差。
In the twin cooling-strip and twin roll rapid solidification method, the metal strip has lateral thick difference.
通过改变轧辊、板带表面的应力分布，来得到理想的带材凸度、板形和厚差。
Optimum profile, shape and thickness difference of strip can be obtained by means of changing stress distribution of load on the surface of strip.
