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.
