摘　　要：根据二维稳态热传导方程及其边界条件 ,运用有限差分法求解板坯连铸机拉矫辊断面的温度场 ,并考虑了辊子材料物性随温度的影响 。Based on the heat transfer equation of two dimensions and the boundary condition, the thermal field of the withdrawing straightening roller of caster is calculated by finite differential equation. The thermal property of the material is taken into account and a satisfied result acquired.
