摘要
根据快速超薄铸轧机铸轧辊的特点 ,从热弹性力学的角度建立了热弹耦合方程并对其求解。综合接触压力 (轧制力分布 )模型 ,确定了铸轧辊温度场边界条件 ,得到了超薄铸轧机铸轧辊变形的计算模型。利用此模型计算了某铸轧机铸轧辊的温度场和变形量 ,计算结果与现场测试数据吻合较好 ,表明所建模型正确可信。通过对铸轧辊应力分析计算发现在不同半径处应力性质有突变 ,从而找到了辊芯与辊套滑移。
According to the characteristics of the thin-gauge high-speed roll casting roller, based on thermo-elasticity mechanics, the stress-strain field coupling thermal-force was analysed and calculated for the thin-gauge high-speed roll casting roller, and it was found that the stress in different radius changes suddenly, which is one of the basic reason of slide between the roll-cover and roll-core. The result fits well with the testing data. This indicates the model is right and trusty.
