摘要

塑性变形的影响之一是成形金属的温度升高。轧制压力、摩擦应力和接触状态在沿变形区的不同区域表现出不同的特性,从而导致热量的产生和传递状态不同,因此板带温度会发生复杂的变化过程。本文介绍了根据 0.5-4.0 米/秒范围内的轧制速度,在轧制带宽和工作辊表面的多个点进行温度测量的实验结果。结果表明,带钢温度和工作辊温度都明显取决于轧制速度,带钢温度的升高幅度更大。在很高的轧制速度下,轧制板材的温度甚至可能超过 1000 摄氏度,这对轧辊表面可能形成沉积物是不利的。

INFLUENCE OF ROLLING SPEED ON THE TEMPERATURE FIELD DURING COLD ROLLING OF ALUMINIUM SHEETS
One of the effects of plastic deformation is an increase in the temperature of the formed metal. The rolling pressure, friction stress, and contact state show different characteristics in different zones along the deformation zone, which causes the heat generation and transfer states to be different, so the strip temperature is subject to a complex change process. The paper presents the results of experimental temperature measurements at several points on the width of the rolled strip and on the surface of the working rolls depending on the rolling speed in the range of 0.5-4.0 m/s. The results obtained showed a clear dependence of both the strip temperature and the working roll temperature on the rolling speed, with the increase in strip temperature being more intense. At very high rolling speeds, the temperature of the rolled sheet may even exceed 1000C, which is unfavourable due to the possibility of the formation of deposits on the surface of the rollers.
