rolling velocity meaning in English

滚动速度
横摇速度

Larger rolling velocity gives better materials filling in the ring section contour
同时发现，轧制速率影响环件轧制的成形性能，较大的轧制速率有利于环件轮廓填充。
The results show that improving the rolling velocity and reducing the galvanizing time will result in reduction of strength loss after galvanizing , and increase of bend torsion valve , thus productivity is improved
结果表明：提高收线速度，减少浸锌时间，镀后强度损失减小，弯扭值提高，生产效率提高。
