不锈钢轧制退火酸洗机组相关计算及实践

Calculation and Practice of Stainless Steel Rolling Annealing and Pickling Line for Stainless Steel

轧制退火酸洗机组是不锈钢冷轧领域技术最为复杂的生产线,已成为不锈钢冷轧领域装备技术发展趋势。本文介绍了不锈钢轧制退火酸洗机组工艺流程、主要工艺参数和计算,以及活套套量、辊身长度等主要参数的选择和计算,介绍了全线纠偏数量、布置以及纠偏计算。利用生产现场测试验结果来证明八字辊纠偏与双辊纠偏的组合纠偏理论方向正确,为轧制退火酸洗机组稳定通板设计提供参考依据。

The stainless steel rolling annealing and pickling line is the most complex production line in the field of stainless steel cold rolling,which has become the development trend of equipment technology in the field of stainless steel cold rolling.The technological process,main technological parameters and calculation of stainless steel rolling annealing and pickling line were introduced,and the selection and calculation of main parameters of looper was introduced,for example the looper quantity and the length of the rollers,and introduces the quantity、layout and calculation of strip centering device.Using the test results in the site to prove that the direction of the combined the zigzag centering roller and the double centering roller strip centering theory is correct.It provides reference for the design of stable strip running of rolling annealing and pickling line.
