摘　　要：对胎圈钢丝用盘条C82DA生产过程吐断问题原因进行了分析,发现配辊时在保障BGV各机架间辊径差最大值不超过1 mm,相邻机架间辊径差不超过0.5 mm,同时通过对工人加强培训,强化操作,适当调整轧机压下量、科学换槽、安装导卫做到牢而不偏等,能够有效减少或避免吐断的发生。The reasons of laying fracture of C82DA wire rod for the production of bead wire were analyzed.It was found when the maximum difference of the roll diameter among the stands of BGV and the difference of the roll diameter between the neighbor stands in the roll matching in the BGV was guaranteed less than 1 mm and 0.5 mm,at the same time,by reinforcing the training of the workers and their operation,adjusting the screw-down space of the rolls properly,changing the groove of each stand regularly and scientifically,mounting the roller guide stably and unbiasedly,the occurrence of laying fracture could be reduced or even prevented.
