In recent years, the rise in energy prices in some industries such as the steel industry has led to the optimal use of it in manufacturing units as a strategic issue. Because energy costs directly affect the price of a product, they can be reduced by using the simulation process of production processes. Regarding the costly process and unfavorable conditions of batch annealing products, in this Research, continuously anneal was simulated in laboratory conditions. For this purpose, an induction power supply with radio frequency was used to simulate annealing process. First, the accuracy of this test was validated using two types of steel, a High-strength low-alloy steel E275 and DX54D- Interstitial Free steel. These two steel are currently being manufactured at Mobarakeh Steel Company and are continuously annealed at Chahar Mahal Automotive Sheet Factory. The initial tests were designed and performed to obtain a good match between the mechanical properties (including tensile strength, tensile yield and strain hardening exponent) from laboratory simulations and real conditions. The optimization of the bake hardening properties of DX54D- Interstitial free steel was carried out based on the highest bake hardening index and yield strength. Bake hardening is a kind of heat treatment that is applied at a temperature of 180 ° for 20 minutes to the final shape of the piece at the baking stage of the component. For this purpose, the effect of annealing temperature of 840 to 860 ? was studied on the bake hardening properties of the steel. The results of the experiments showed that with increasing the annealing temperature, the mean grain size increased from 13.92 ± 6 ?m to 39.8 ± 7 ?m. Also, with increasing the annealing temperature, the tensile strength of steel dropped from 130 MPa to 120 MPa. With baking hardening operation, the tensile strength of steel was achieved at a temperature of 840 ° C (150 MPa), which, with increasing temperature, reduced the baking hardness from 20 MPa to a negative value. The reason for this was the occurrence of over aging during the cooling of the steel at the annealing stage as well as the increase in grain size. Hardness results showed that with increasing annealing temperature, the hardness of the samples was reduced, which showed that the hardness of the specimens increased at each temperature by performing bake hardening operations.
