AI Technical Summary
Existing photovoltaic support materials suffer from high cost, low durability, serious environmental pollution, and high smelting difficulty, making it difficult to meet the photovoltaic industry's demands for low cost, lightweight, green, and high corrosion resistance.
By adding elements such as Si, P, Cr, and Cu, and combining them with specific process parameters, a thin-gauge 800MPa grade hot-rolled weathering steel plate for photovoltaic brackets was prepared. By adopting reasonable heating temperature and controlled rolling and cooling processes, the "copper brittleness" defect was avoided, and high strength and excellent plasticity were achieved. The metallographic structure is polygonal ferrite + a small amount of pearlite.
It significantly improves atmospheric corrosion resistance, reduces alloy costs, achieves high strength and excellent plasticity, meets the green and lightweight application requirements of photovoltaic brackets, and reduces material usage and construction costs.
