Stability of the rolling process of ribbed bars based on the analysis of strength parameters

The article presents the results of the strength properties of 12 ÷ 24 mm ribbed bars used for concrete reinforcement. The strength properties and the ribbing geometry of the ribbed bars is a key factor in ensuring the safety of building structures. Therefore, the continuous analysis of the mechanical parameters of ribbed bars and the reasons for their change is essential for any rolling mill. This article aims to present an analysis of the strength properties of ribbed bars made of high ductility steel in 2021 in a selected production plant, and then, based on the obtained results, to perform an analysis aimed at verifying the stability of the rolling process.
