摘要: 运用有限元软件ANSYS热分析模块对浇铸0.2%C钢水的10 mm铜结晶器壁面的温度场、应力场及位移场的分布状况进行数值模拟,比较得出在不同换热系数工况下结晶器壁面的恶劣服役部位的安全性。结果表明,结晶器热面峰值温度为525 K,冷面的峰值温度为475 K;结晶器外壁圆角变形值为0.789 mm,较内壁变形大;结晶器最大等效应力和最大应变均出现在钢液与空气接触的内壁圆角处,分别为218 MPa和0.002 079。结晶器温度、变形和应力均满足连铸安全性要求。

Abstract: The numerical simulation on distribution of temperature field,stress field and displacement field of copper mould wall with 10 mm thickness for casting liquid of 0.2% C steel has been carried out by using finite element analysis software ANSYS/thermal,with comparison to get the safety of serious service part of mould wall at conditions with various heat exchange coefficient. Results show that the peak temperature of mould hot surface is 525 K and the peak temperature of mould cold surface is 475 K; the deformation of outside wall round corner of mould is 0.789 mm it is larger than that of inside wall; the max equivalent stress and max strain occur at inside wall round corner at which liquid contacting air,and are respectively 218 MPa and 0.002079. The temperature,deformation and stress of mould all meet the requirement of concasting safety.
