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，得到了较满意的结果。
Based on the two-dimension heat transfer equation and boundary condition,the thermal fieldof the pulling-straightening roller of slab casting machine is calculated by finite differential equation.The thermal property of the material is taken into account and satisfying result is acquired.
