Abstract

The invention discloses a wear-resistant alloy steel material for fan blades of a wind-driven generator. The wear-resistant alloy steel material comprises the following components in percentage by mass: 0.02-0.14% of C, 7-10.5% of Cr, less than 1.5% of Mn, 0.5-1.5% of Si, 0.01-0.05% of P, 0.03-0.08% of S, 3.5-5.5% of Al, 1.2-2.2% of W, 0.05-0.10% of V and the balance of Fe. The wear-resistant alloy steel material for fan blades of a wind-driven generator, which is disclosed by the invention, has the advantages of good comprehensive mechanical properties, higher strength and fatigue strength, yield strength which can reach above 1010MPa, tensile strength which can reach above 1250MPa, hardness which can reach above 530Hv and excellent toughness.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a wear-resistant alloy steel material for wind blades of wind power generation. Background technique [0002] Wind power is a mature and cheap power resource, which consists of three-phase permanent magnet generator, wind blade, tower, cable, controller, inverter, battery pack and so on. When the wind pushes the fan blades to rotate, the three-phase low-voltage alternating current generated by the special control circuit is converted into direct current to charge and store the battery. When in use, the inverter (inversion power supply) generates 220v, 50Hz alternating current, which is as convenient as using grid power supply, and it does not cost money to invest in long-term electricity at one time. A set of 300W wind turbines can meet the electricity consumption of a family's TV, DVD, satellite receiver, electric fan, lighting, etc. If a fan with a hi...
