用宽面薄板切边系统取代无张力动力驱动圆盘剪切边系统,不但减少了设备投资和占地面积,而且节约大量能源。为了消除宽面薄带钢在张力下纵切时的翘曲变形,带钢必须与下圆盘剪刃筒形成一定的包角θ,该角度应大于两圆盘剪刃重叠区所对的圆心角。 Replacing the tension-free power-driven shearing edge system with a wide-face sheet trimming system not only reduces equipment investment and floor space, it also saves a lot of energy. In order to eliminate the warping deformation of wide-faced thin strip under tension under longitudinal slitting, the strip must form a certain wrap angle θ with the lower disk-cutting edge barrel, which angle should be larger than the center of the circle angle.
