补充资料:轧辊偏移量
轧辊偏移量
offset of rolls
zhagun Pianyiliong轧辊偏移t(offset of rolls)四辊轧机工作辊连心线与支承辊连心线之间的距离,用。表示(见图)。采用偏移量的目的是为了克服工作辊在水平方向的歪斜,保证产品质量;便于安装工作辊;减少对轧很轴承的冲击及提高工作辊的稳定性。工作辊偏移量e可按下式计算~(R。+R)rofo e二全一 -一Ro串 工作辊偏移量式中R。为支承辊半径;R为工作辊半径;r。为支承辊颈部半径,一般r。一(。.5一0.75)R。;f0为支承辊轴承摩擦系数,一般f0一0.001一0.006。对于各种类型四辊冷轧机,e的推荐值如表所列。 e的推荐值一瓦默蒸万斗书汗 。。。mm四辊冷车L机…、一5 “somTn四辊冷车七机…3一4 对于不可逆式轧机(见轧机),工作辊应偏向出口一侧设置。对于可逆式轧机,应保证在轧制各种产品的最后一个轧制道次(即奇数道次)时,工作辊应偏向出口一侧设置,以保证产品质量(如带钢板形等)。在偶次轧制道次时,若。道在表中所列的推荐值以上,轧制过程仍稳定可靠。 (赵以相)
