目的在金属板的轧制方面,使上下工作辊的圆周速度不同,可防止轧材的上下非对称性,概况图1是表示由异速轧制法进行轧制的状态图,图2是表示轧辊速度比和轧制负荷的关系。轧制金属板的时候,若把上下工作辊 a,b设定成不同圆周速度时(见图1),则和上下工作辊相同圆周速度的轧制法相比,可大幅度减少轧制负荷。这是因为,出于上下轧辊不同圆周速度

Aiming to prevent the up-and-down asymmetry of the material to be rolled, wherein Figure 1 is a view showing the state of rolling by a non-speed rolling method, Figure 2 Roller speed ratio and the relationship between the rolling load. When the metal plate is rolled, if the upper and lower work rolls a and b are set to different peripheral speeds (see FIG. 1), the rolling load can be significantly reduced as compared with the rolling method in which the upper and lower work rolls have the same peripheral speed. This is because of the different circumferential speeds of the upper and lower rolls
