Analysis of Bending and Fracture of Hot-rolled Ribbed Steel Bars
By analyzing the chemical composition,mechanical properties,macroscopic fracture,microstructure,Vickers hardness,and production process of the bent and fractured steel bars,the main cause of the fracture was found to be that the construction personnel used a small diameter bending core to bend the steel bars with segregated microstructures,resulting in the fracture of the steel bars.Improvement suggestions for the production and processing technology of steel bars were proposed.
