Abstract: In corresponding with profile shape defect trouble about 1.2 mm x (250 ~ 380) mm strip of 301S and 301B cold rolled austenite stainless steel at steel works, the influence of change of strip width on profile shape during twelve-high mill rolling process (reduction 18% -26% , rolling force 750 ~ 1 600 kN) is obtained by analysis on a vast amount practical production data. Results show that as the width of strip is larger, with increasing rolling force or shifting intermediate rolls along axial direction to median, the central buckling profile shape defect decreases ； and as width of strip is smaller, with decreasing rolling force or shifting intermediate rolls along axial direction to both sides, the both-side edge buckling profile shape defect shall be reduced.

摘要： 针对钢厂301S和301B冷轧奥氏体不锈钢1.2 mm×(250~380)mm带钢的板形缺陷问题,通过分析大量的生产数据,得出12辊轧机轧制过程(压下率18%~26%,轧制力750~1 600 kN)带材宽度的变化对板形的影响。结果表明,当带材的宽度较大时,增大轧制力或将中间传动辊沿轴向向中间窜动,会减少中松板形缺陷;当带材的宽度较小时,减少轧制力或将中间传动辊沿轴向向两侧窜动,会减少双边浪板形缺陷。
