宝钢1220冷连轧机轧制规程综合优化技术的研究

BaoSteel 1220 Cold Tandem Mill Rolling Regulation Optimization

轧制规程作为冷连轧生产中的一个重要过程参数,不但影响机组的产能,而且对成品的板形与表面质量有着重要的影响。因此,如何设定出合适的轧制规程就成为冷连轧机组的重要攻关课题。为此,经过大量的现场试验与理论研究,充分结合宝钢1220五机架冷连轧机的设备与工艺特点,以成品带材板形良好、各架电机相对负荷均匀以及划痕发生概率小为控制目标,提出了一套轧制规程综合优化方案,并将其应用到生产实践,取得了良好的使用效果,具有进一步推广应用的价值。

Rolling regulations as the important processing parameters in cold rolling can influence not only the output but also the shape and surface quality. So, how to set rolling regulations is becoming an important topic for cold tandem mill. Combined with equipment and craft feature of BaoSteel 1220 five-stand cold tandem mill, this paper put forward a set of roiling regulations optimization version, making good shape and relative load uniform and minor probability of scratching as controlling aim, and applied it to productive practice and got good effect. This study is of further extension value of application.
