Abstract: Using the inverse algorithm of heat transfer and the nonlinear estimation method, matching calculated values with measured ones, the interfacial heat transfer coefficient at casting/Cu mould interface was determined.The results show that the interfacial heat transfer coefficient at Al/Cu interface changes in a range of 4.0×10^3-1.0×10⁵W·m^-2·K^-1 and its average value is in a range of 5.0×10³-7.0×10³W·m^-2·K^-1.
