In modern large-scale building steel structure projects, common carbon steel plates, as core load-bearing materials, must withstand enormous static and dynamic loads while requiring extensive on-site welding for component connections.
Non-metallic inclusions in continuously cast billets are one of the core factors causing surface cracks in hot-rolled plain round rebar.
It is necessary to avoid reversing the roll after winding is completed to prevent the inner ring from loosening due to tension release, which could lead to mis-winding.
Within reinforced concrete systems, hot-rolled plain round rebars, as a fundamental and crucial component, silently bear the heavy responsibility of constructing the "steel skeleton," providing solid support for the entire structure.
Regularly inspecting and replacing the descaling nozzles, and cleaning the descaling pump and motor, can ensure stable pressure and uniform impact force in the descaling system, thereby improving the descaling effect.
Processes such as shot peening and rolling can effectively suppress crack initiation and propagation by introducing residual compressive stress on the material surface.
