采用纵轧理论和功率转换原则对异步交叉轧制的能耗特性进行了分析，并进行了实验验证．研究表明：交叉角有一临界值θｃｒ，随着交叉角的增大，轧制能耗下降，当交叉角θ增至临界值θｃｒ时，能耗最小，θ＞θｃｒ后，能耗基本不变；随异步比增大，轧制能耗亦下降，当异步比ｉ增至临界值ｉｃｒ时，能耗最小，ｉ＞ｉｃｒ后，能耗则上升．而且交叉角θ愈大，其对应的ｉｃｒ亦愈大．即当交叉角和异步比皆为其临界值θｃｒ和ｉｃｒ时，异步交叉轧制的综合能耗最小．
The energy consumption characteristics of asynchronous cross-rolling are analyzed by using the theory of longitudinal rolling and the principle of power conversion, and experimental verification is carried out. The results show that the cross angle has a critical value of θcr, and the energy consumption of the rolling decreases with the increase of the crossing angle. When the crossing angle θ increases to the critical value θcr, the energy consumption is the smallest. After θ> θcr, As the asynchronization ratio increases, the energy consumption of the rolling also decreases. When the asynchronic ratio i increases to the critical value icr, the energy consumption is the smallest. When i> icr, the energy consumption increases. And the greater the intersection angle θ, the greater the corresponding icr. That is, when the cross angle and the asynchrony ratio are both the critical values θcr and icr, the cross-rolling energy consumption is the smallest.
