针对马钢CSP轧机工作辊不均匀磨损严重影响了带钢板形的问题,对CSP轧机F3~F4的磨损辊形进行了分析,指出了使用高速钢轧辊的必要性。针对高速钢轧辊的使用条件进行了大量的试验,通过分析现场的生产数据如轧制力、轧辊温度及轧辊表面氧化膜,制定了马钢CSP投入高速钢轧辊的使用工艺,并实现了该工艺条件下的长期稳定使用,通过现场实绩表明,使用高速钢轧辊大大改善了工作辊在线不均匀磨损,提高了热轧带钢的板形质量。
Aiming at the problem of strip shape of CSP mill, the worn roll shape of CSP mill F3 ~ F4 was analyzed. The necessity of using high speed steel roll was pointed out. A large number of experiments have been carried out on the conditions of use of high speed steel rolls. By analyzing production data such as rolling force, roll temperature and oxide film on the roll surface, the use process of CSP in high speed steel roll has been established and the process has been realized Under the conditions of long-term and stable use, through the field performance shows that the use of high-speed steel roll greatly improved on-line work roll uneven wear and tear, improve the quality of hot-rolled strip shape.
