Abstract
The invention discloses a direct drive type fixed shaft for a wind-driven generator. The direct drive type fixed shaft comprises a metal body made of alloy material, and the alloy material is composed of, by weight, 1-2% of C, 1.9% of S, 0.7% of Mo, 2.3% of Re, 1.3% of Bi, 0.7% of Sc and the balance Fe and inevitable impurities. The alloy material is prepared through the steps of 1, fusing Fe, C, Fe-S alloy and Fe-Mo alloy in a protective atmosphere; 2, regulating the temperature to 925 DEG C, adding Fe-Re alloy, Fe-Bi alloy and Fe-Sc alloy into flux, stirring the flux uniformly and making the flux stand for 43 minutes in a heat preservation mode; 3, guiding argon gas into the flux, making the flux stand, cooling the flux to 625 DEG C and obtaining the alloy material through pressure casting. The direct drive type fixed shaft for the wind-driven generator is high in strength, excellent in corrosion resistance and weather resistance and capable of being used for a long time.
