摘　　要：针对镀锡板生产中存在的翘曲控制问题,考虑到镀锡基板与镀锡板翘曲高度和方向在上下游工序的遗传和演变,研究了一次冷轧镀锡基板和二次冷轧镀锡基板在平整和二次冷轧时翘曲的控制策略,分析了卷取过程对不同钢种、规格镀锡板翘曲高度的影响,研究了镀锡线拉矫机的翘曲控制特性。在此基础上,提出了镀锡板在平整/二次冷轧、拉矫以及卷取过程的翘曲控制策略,并在某镀锡板生产厂得到应用,镀锡板产品翘曲高度控制精度得到大幅提升。Aiming at problems of the warping control on tinplate,considering the heredity and evolution of the warping height and the direction on tinplate substrate and tinplate,the warping control strategy of the single cold rolled and double cold rolled tinplate substrate was researched,the influence of the coiling process on the warping height of the tinplate with different steel grades and specifications was analyzed,and the warping control characteristics of tension leveler in electrolytic tinning line was studied.On this basis,the warping control strategy of the tinplate during the temper rolling/double cold rolling,tension leveling and coiling process was put forward.It had been applied in a tinplate manufacturing plant,the accuracy of the warping height control of tinplate products had been greatly improved.
