Abstract
A method for heat treating a mold cast product by releasing the product from a mold and hardening the product. Since the mold release is performed when a surface layer of the product held in contact with the mold has a hardening allowing temperature and after it becomes a shell-shaped solidified layer, the product immediately after release from the mold has a heat suitable for hardening. Using this heat, the product is thereafter hardened by means of a cooling agent. As a result, a heating process required for hardening can be omitted, thereby achieving energy conservation.
