The invention discloses F-shaped steel for magnetic levitation rails with high magnetic flux density and a production method thereof. The F-shaped steel contains the following components by weight percent: 0.04-0.07% of C, 0.08-0.20% of Si, 0.5-0.8% of Mn, less than or equal to 0.015% of P, less than or equal to 0.015% of S, 0.015-0.030% of Nb, 0.03-0.05% of Als and the balance of Fe and impurityelements. According to the invention, the F-shaped steel for magnetic levitation rails with high magnetic flux density and excellent mechanical properties is acquired in the manner of designing steelcomponents, controlling quantity and size of impurity grains in the steel-making process and supplementing by high-temperature quick rolling so as to solidly dissolve alloying elements in steel and accelerate quick growth of crystal grains. According to the invention, the magnetic flux density of F-shaped steel is greatly increased and is 15% higher than that of present F-shaped steel.
