摘　　要：对不锈钢热退火酸洗线破鳞机使用过程中延伸率低、破鳞效果差的情况进行了分析,找出影响破鳞机延伸率提高的原因。通过改进破鳞机工作辊轴承和包角,优化油缸压下量,使破鳞机延伸率由原来的0.5%提高到了2%以上。Situation of lower elongation rate and worse descaling effect of stainless steel hot annealing and pickling line scale breaker has been analyzed to find out cause that influenced elongation rate improvement of scale breaker. By improving working roll bearing and wrap angle of scale breaker and optimizing oil cylinder reduction,the elongation rate of the mill has been increased from 0. 5% to 2% and above.

关 键 词：破鳞机 延伸率 轴承 压下量
