摘　　要：研究连续酸洗薄规格汽车板生产中影响出口堆钢的主要因素,实现薄规格汽车板在连续酸洗线的稳定生产。统计堆钢事故,分析堆钢事故过程,发现剪前夹送辊打滑、出口剪剪切后带头下弯及出口飞剪内部堆钢等是关键影响因素,通过进行设备调整和改造,在涂油机前增加一组夹送辊,剪前夹送辊改成胶辊,油膜测厚仪前托辊位置调整等措施,解决影响堆钢发生的关键因素。设备改造和调整后,减少带钢及辊子表面残油及增加夹送辊压力有助于增加夹送辊提供给带钢的动力,减小堆钢发生概率。通过设备改造,增加带钢摩擦力减少打滑,调整托辊位置避免了带钢折弯的发生,薄规格汽车板堆钢问题得到本质化的解决。To study the main factors affecting export stacking steel in the production of continuous pickling thin gauge automotive panels,and to achieve stable production of thin gauge automotive panels on the continuous pickling line.Statistical analysis of steel stacking accidents revealed that slipping of the pinch roll before shearing,bending of the head after shearing at the outlet,and internal steel stacking in the outlet flying shear were key influencing factors.Through equipment adjustments and modifications,a group of pinch rolls was added in front of the oiling machine,the pinch roll before shearing was changed to a rubber roll,and the position of the front support roller of the oil film thickness gauge was adjusted to address the key factors affecting the occurrence of steel stacking.After the equipment modification and adjustment,reducing residual oil on the surface of the strip steel and rollers and increasing the pressure of the pinch roller help to increase the power provided by the pinch roller to the strip steel and reduce the probability of steel stacking.Through equipment modification,the friction force of the strip steel is increased to reduce slipping,and the position of the roller is adjusted to avoid the occurrence of strip steel bending.The problem of stacking steel for thin gauge automotive plates has been fundamentally solved.
