| Abstract: | Adopting finite difference method, the temperature fields of large section die block during quenching were calculated. A set of cooling simulation equipment was designed. The equipment was used to simulate the cooling course of arbitrary site of steel block with large section during quenching with small samples. The hardness of the small samples was determined respectively. The quenching hardness distribution in large section die block was established by matching the calculated cooling course with the hardnoss of the corresponding small sample. This method of simulation of quenching hardness distribution in large section die blocks is accurate, convenient and feasible and can be widely applied. |
