摘要 通过建立数学模型,研究了轧板在粗轧、精轧过程中的温度变化 为了正确估计轧板的温度,应考虑轧板-轧辊接触面以及轧辊间的热传递 数值结果表明 ,轧辊的冷却作用对轧板温度分布有显著影响 此外 ,对轧板温度进行数值分析时须考虑氧化皮和轧板 A mathematical model has been studied to predict histories of slab during rough and finish rolling.To estimate temperature of the slab correctly,the heat transfer in the roller/slab interface and in the rollers has been considered.The numerical results show that the roller chilling has a significant effect on the temperature distribution in the slab.In addition,the temperature of slab is numerically analyzed by considering the effect of emissitivity of oxide scale and lubricant film at the interface slab/roller.
