目的 研究拉矫破鳞参数对带钢表面酸洗速率的影响规律。 方法 运用自行研发的拉矫破鳞机对带钢试样进行试验,运用数学软件对实验数据进行拟合,得出破鳞参数对酸洗速率的影响模型,并分析其规律。 结果 随着张紧力和压下量的增大,带钢延伸率增加,酸洗时间减少,当压下量大于 36 mm时,酸洗时间基本不再变化。 结论 影响破鳞效果的主要因素是压下量,压下量对酸洗速率的影响存在饱和点,超过这个点酸洗速率不会发生明显的变化;破鳞机的压下量对酸洗时间的影响成指数关系。

Objective To study the influencing law of descaling parameters on pickling speed. Methods The strip sample was descaled by the tension-bending leveler. The effect of descaling parameters on pickling speed was analyzed and fitted using mathematical software, to obtain the influencing model of descaling parameters on pickling speed and analyze the law. Results With the increase of insert depth of roller and tension of descaling machine, the strip elongation increased and the pickling time reduced. The pickling time changed slightly when the screw down amount exceeded 36 mm. Conclusion Tests showed that the strip elongation was mainly impacted by the screw down amount, and the pickling time decreased insignificantly when the screw down amount exceeded the saturation point. The screw down amount affected the pickling speed exponentially.
