Process control for optimizing factors such as product quality, energy and cost becomes increasingly important in
industry. In this study, the analysis and optimization of the rolling parameters were carried out in steel profile hot rolling process
applied in Kar-demir Rolling Industry Trade Ltd. Co. which execute R&D and production activities in the rolling industry. In this
context, the analysis of the rolling parameters such as roll position, force, moment, temperature, thickness and crushing amount
belonging to rolling mechanics were carried out based on the empirical models widely used in the hot rolling process. As the
result of the study, optimum roll positioning and crushing amount calculations are proposed to minimize energy and time cost.

- In hot rolling which is one of the plastic forming, the operation called “Tempcore Process” provides to obtain different
microstructures from the surface to the core by quenching before the cooling platform where the conventional cooling is performed
in steel profiles come out of the finish workbench which is the last stage of rolling. The purpose of this process is to obtain a
martensitic structure up to a certain thickness from the surface of the profiles to the center and tempering the martensite with the
effect of high temperature in the core. Thus, a hard and tough product is manufactured. However, it is ensured that the linearity
of the product is maintained at the platform exit. In this study, the Tempcore Process was carried out NPU and Equal Angle type
profiles of S275JR quality steel produced in Kar-demir Rolling Industry Trade Ltd. Co. and the effects of this process on the
structural form and mechanical properties of the profiles were investigated. In this context, pre- and post-Tempcore Process,
hardness measurements, tensile and impact tests were applied and the results were assessed comparatively.
