Wear-resistant and corrosion-resistant hypoeutectoid steel rail and production method thereof
The invention relates to a wear-resistant and corrosion-resistant hypoeutectoid steel rail, which comprises the following chemical components in percentage by weight: 0.50 to 0.70 percent of carbon, 0.10 to 0.80 percent of copper, 0.01 to 0.50 percent of nickel, 0.10 to 0.70 percent of chromium, 0.03 to 0.12 percent of vanadium, 0.010 to 0.025 percent of phosphorus, 0.001 to 0.009 percent of sulfur, 0.8 to 2.0 percent of silicon and manganese, and the balance of iron and inevitable impurities. According to the production method of the wear-resistant and corrosion-resistant hypoeutectoid steel rail, copper, nickel, chromium, vanadium, silicon, manganese, phosphorus and sulfur or one or more of niobium, molybdenum, boron and rare earth elements are added into the hypoeutectoid steel rail with the carbon content of 0.50-0.70%, heating and rolling are performed again after smelting and casting, and online heat treatment is performed through hot rolling or rolling waste heat. The corrosion-resistant effect of the steel rail is effectively improved, the corrosion resistance of the surface layer of the produced steel rail is improved, and the steel rail has good wear resistance and corrosion resistance in a humid line environment and meets the corrosion-resistant effect in a high-temperature humid tunnel environment.
