1) high reduction
大压下
2) large percent reduction
大压下量
1.
The surface crease presenting in rolling with large percent reduction is simulated with finite element method,the law that process parameters affect rolling quality is found out.
采用有限元法对大压下量轧制工艺下,轧件表面折皱的产生进行了模拟分析,找到了工艺参数对轧件质量的影响规律,经过对原工艺参数进行调整,达到了降低钢材表面折皱缺陷的目的。
3) Heavy Width Reduction
宽度大压下
4) Low Temperature High Reduction
低温大压下工艺
5) heavy reduction rate rolling
大压下率轧制
1.
Research on heavy reduction rate rolling of AZ31 Magnesium alloy;
AZ31镁合金大压下率轧制的研究
6) finishing pass heavy drought
末道次大压下
1.
A new process of finishing pass heavy drought was researched to enhance finished property of the micro-carbon deep-drawing sheet,experimental results show that the new process refines hot rolled grain obviously and advances the formation of cold rolled texture 〈111〉 greatly,thus enhances the cold rolling property(IE,n,r) remarkably.
对微碳深冲板进行末道次大压下率轧制的新工艺试验研究以期提高其成品性能。
