人们采用不对称热轧,是为了达到以下几种目的:由于在变形区造成纵向拉应力而降低能量动力参数(主要是轧制力);由于带钢上层和下层流动速度不同而造成带钢前端从轧辊中出来时有向弯曲;通过减少负荷比较大的轧辊的直径而均衡两根轧辊上的扭矩;通过减少轧辊重磨时的减径量而减少轧辊有效层的消耗量。不同直径工作辊的采 Asymmetric hot rolling is used to achieve the following goals: to reduce the energy dynamic parameters (mainly the rolling force) due to the longitudinal tensile stress in the deformation zone; to cause the front end of the strip due to the difference in the flow velocity between the upper and lower layers of the strip Bending out when coming out of the roll; equalizing the torques on the two rolls by reducing the diameter of the larger-load roll; and reducing the consumption of the effective layer of the roll by reducing the amount of reductions during the roll refinish.
