    • PROBLEM TO BE SOLVED: To improve accuracy in plate thickness control, while securing stable strip-feeding performance.SOLUTION: In a plate thickness control device 4, a limit setting part 43 sets an upper limit value of a closing directional variation in rolling reduction when adjusting work rolls 31a and 31b in the closing direction and an opening directional variation when adjusting the work rolls 31a and 31b in the opening direction, based on at least one of an allowable value of a meandering amount of a steel plate S, a mass flow compensation amount and steepness of a shape change. A plate thickness control part 41 controls a plate thickness of the steel plate S by adjusting the rolling reduction within a range in which a variation in the rolling reduction before and after an adjustment does not exceed the upper limit value set by the limit setting part 43.
    • 要解决的问题:提高板材厚度控制的精度,同时确保稳定的送纸性能。解决方案:在板厚控制装置4中,限位设定部43设定轧制压下的闭合方向变化的上限值, 基于钢板S的蜿蜒数量的容许值,质量流量,质量流量等中的至少一个,在打开方向上调整工作辊31a,31b,使其在关闭方向上调整工作辊31a,31b,以及打开方向变化 补偿量和形状变化的陡度。 板厚控制部41通过将调整之前和之后的轧制压下量的变化不超过由限制设定部43设定的上限值的范围内调整压下率来控制钢板S的板厚。 。
