The heat transfer efficiency of the mold plays a crucial role in the efficient casting process. At the high-speed continuous casting strategic research project funded by the National Natural Science Foundation of Canada, it was carried out on the AtlasSteel steel billet caster An industrial test was conducted to study the heat flux change of the mold during high speed continuous casting of stainless steel. 42 thermocouples were installed on the 4 walls of the mold. The temperature signals under different process conditions were recorded in the computer at a frequency of 10 Hz. According to the average temperature of each point, a set of calculation program for IHCP (InverseHeatConductionProblem) is elaborated. The method of modeling is elaborated. The program is used to calculate the distribution of heat fluxes along the crystallizer under different casting velocities and different steel grades The effects of casting speed and steel heat transfer on the mold were discussed
