Özet
The production of steel materials has an important place in the world. In recent years, steel materials have been frequently preferred in many sectors due to the mechanical resistance and high friction protection of steel materials. In this study, the effect of the chemical composition of steel materials, rolling speed, and the water-cooling system during rolling on the mechanical properties of the material (yield strength, tensile strength, impact toughness) was investigated. The mechanical behaviors of three different grades of materials were examined. According to the obtained results, the direct influence of manganese, vanadium, and aluminum elements on mechanical properties was observed. Increasing the amount of manganese in the steel material led to an increase in the yield and tensile strength of the material while using vanadium and aluminum elements together. Increasing their amounts increased the material's notch toughness. Furthermore, the effects of two other important parameters, rolling speed, and the water-cooling pumps in the rolling system, were examined. As a result, it was determined that reducing the rolling speed improved the mechanical properties of the material, and increasing the water-cooling pumps also improved the mechanical properties because it allowed the material to receive more water.
