变刚度轧制

b jangongdu zhazhj变刚度轧制(rigidity ehange:olling)板带轧制中改变轧机承受弹性变形能力的轧制。在板带材轧机上，利用不同的辊缝调节量，抵消因轧制力引起的轧机的局部或全部弹性变形，可以获得理想厚度偏差的板带。轧机固有的自然刚度系数Km是不变的(见轧机刚度系数)，它是随轧机固有结构和材质而定的常数。在轧机固有结构基础上由于增设了液压装置，实际发生作用的轧机刚度系数随辊缝调节量的不同而发生变化，因此称它为刚度可变，这时的轧机刚度称为等效刚度或当量刚度，这时的轧制就是变刚度轧制。 轧机刚度可变控制的基本方程为: △尸(l一C)△尸 助’~二=.丫汁一一二二二苍升 Km KE式中抓‘为轧辊位置补偿之后的带钢轧出厚度偏差;C为轧辊位置补偿系数;KE为轧机的等效刚度系数。所谓轧机刚度可变控制，实质上也就是改变轧辊位置补偿系数C，即改变K:。在某一特定结构的轧机条件下，轧机固有的刚度系数K，是一个常数，因此对C可以作如下的分析: (l)当c~l时，则K。一co，以‘二o。这就意味着轧机的弹跳(见轧机弹性方程)量被100%补偿掉了，即不论来料厚度偏差如何，由于此时轧机等效的刚度系数K:是无穷大，完全可以使带钢的实际轧出厚度达到所要求的尺寸，没有厚度偏差。此种情况下轧辊的辊缝称为恒定辊缝，其等效的轧机刚度称为超硬刚度，或超硬特性。为了稳定起见，取C~。.8一0.9，KE“250。以上，在计算机控制时，其设定值取为K:一3300t/mm。 、，.___，~，_△尸__.△尸__、、 (2)当C一O时，则C等一二O，占衬一气乡~叔，这 、“’州~一’“’乃J“犬m一’“”Krn一“’“。~就说明实际轧出厚度还具有因来料厚度差沙H所引起的厚度偏差队。此时，轧机的等效刚度系数KE就等于轧机原来所固有的(或称为自然的)轧机刚度系数K二，轧机的刚度称为自然刚度，或自然特性。一般来说，轧机的自然刚度系数Km~500~600t/mm。 (3)当。
