英语翻译
This model allows evaluating the mill stretching.The
stretching is used for computing the screw down position of the stand i.e.the
gap.
The mill stretching is defined by a polynomial curve
tuned at the beginning of commissioning.This curve is obtained by
interpolating empty measurements.The model is configured for each stand.
The stretching curve is divided in two parts,a polynomial curve (order 4)
under the nominal force and a line above the nominal force.
Because mills are mostly use in the linear part of the
force,we configure only the following coefficient:
Stretch = a0+a1f
The
nominal force (also called linear force) is the reference force used during
screwdown calibration.

先定义几个专业名词:
1.Stretch:弹跳 在轧钢学中,把轧机牌坊,压下螺栓和轧辊受力后变形称之为弹跳.
2.Screw Down Position:压下位置(压下量)预设某一轧钢道次的垂直名义压缩量
3.Gap:是一对轧辊在受力状态下的间隙.这是由预设的压下量决定的
以下是该段的译文:
这个模型可以预估轧机的弹跳.弹跳是用来计算该道次(架次)的压下量,既”辊缝“.
轧机的弹跳由一多项式曲线来定义的,这个曲线是在首次试车中经调试而定的.这条曲线是通过内插虚值获得的.这个模型是为每一架次定置的.
弹跳曲线分为两部分,一部分为标称压力下的多项式曲线(4阶的)和一条在标称压力之上的直线.由于轧机多数作用在线性力之下,我们仅需确定下列系数
弹跳 =a0+a1f
标称压力(又称线性压力)是在压下标定时的基准压力
