Then a retraction less variable precision gap setting method was put forward based on the characteristic of plate gap setting 基于此特性，提出中厚板电液联合辊缝设定新方法无回缩变精度快速辊缝设定法。
2.
This method can decrease the gap setting time for which the oil column of hydraulic cylinder is not retracted and there is no minute adjustment of oil column for the first several passes 采用该方法，轧制过程液压缸油柱不用回缩，而且前面道次液压不进行微调，从而节省了辊缝设定时间。
3.
The research of the influence of gap setting precision on finishing plate size precision shows that the sensibility of finishing size precision to gap setting precision of the first several passes is low 摘要分析中厚板轧制过程不同道次辊缝设定精度对轧件终轧尺寸精度的影响，证明了轧件终轧尺寸精度对前面道次的辊缝设定精度不敏感。
