In response to the practical requirements of lightweight and high strengthening of solar energy supports,a special hot rolled steel strip for solar energy supports has been successfully developed through a controlled rolling and cooling process,in collaboration with a cold rolling enterprise,using a composition system design of low-carbon,low silicon,and micro titanium.The strip meets the requirements of easy coating and high elongation.The microstructure of this steel strip is pearlite+ferrite,with fine and uniform grains.It has high strength and toughness,while also taking into account good ductility and surface quality,meeting the performance requirements of customers after cold rolling and annealing,as well as the high surface quality requirements of galvanized aluminum magnesium without leakage plating and leakage points.
