摘 要: 运用Galerkin方法 ,得到了在考虑外冷效应情况下的铸轧辊套温度场的近似分析解。实例计算表明 ,所得结果与实测结果相吻合 ,且计算方便 ,精度满足生产需要。 An approximate analytical formula of a roll shell's temperature field is obtained using Galerkin method. The formula takes external cooling effect into account. The calculated results show that the results obtained are in agreament with the actually measured results. The formula is characterized by convenient calculation and high accuracy enough to meet the need of practical production.
