轧机刚度系数
rigidity coefficient of rolling mill
zhalj gongdu xishu轧机刚度系数(rigidity eoeffieient of rollingmill)使轧机产生纵向单位弹性变形所需施加的轧制力。其几何意义为轧机弹性曲线直线段的斜率，记作 dP K~~共气 “m ds式中d尸为轧制力增量;ds为辊缝增量;Km为轧机刚度系数，其量纲为kN/mm。因此，某一轧机的刚度系数可根据轧机的弹性曲线的斜率计算确定。实际上，由于轧制时轧棍和整个车L机在负荷作用下温度升高，辊缝发生变化而成为一个变值，轧辊的圆度和安装偏差会造成轧件的纵向厚度偏差呈高频周期性变化，轧件、一公淤叮派李点- 翻~香爪~~咋今粉~ 轧钢机按机架排列分类 a一单机架;吞一横列式;一顺列式;d一棋盘式;~半连续式;了一连续式宽度也会影响轧辊的弯曲弹性变形等，所以为了提高轧件厚度控制的精确度，轧机的刚度系数一般都通过现场实测方法得到。但也可以在用解析方法分别算出轧辊的刚度系数K，、机架的刚度系数KZ、安全臼的刚度系数K3、压力传感器的刚度系数K4等之后，按下式计算 1 K，~— 1 .1 .1 .1 分+分十含+亡 K:1 KZ’K3’K4因此，K。又称等效刚度。 (赵以相)
