  • Publication number: 20230416882
    Abstract: Chemical compositions of a tire cord steel with high strength and low wire breakage rate may include Nb, V and N, and ([Nb]+[V])/[N] is 3-4.5, [Nb] representing the mass fraction of niobium element, [V] representing the mass fraction of vanadium element, and [N] representing the mass fraction of nitrogen element. The method includes: obtaining a steel billet of the tire cord steel; and sequentially performing a heating-before-rolling, a hot-rolling and a cooling-after-rolling on the steel billet to obtain a wire rod of the tire cord steel. The application of the tire cord steel is to apply the tire cord steel in tire skeleton materials. The strength and toughness of the tire cord steel can be improved by adding Nb, V and N, and then controlling the relationship between Nb, V and N.
