Method for manufacturing component for wind power generation by using waste A3 steel disc

The invention discloses a method for manufacturing components for wind power generation by using waste A3 steel discs. The method uses pure A3 waste steel discs with thickness equal to or less than 1.5 mm as a raw material, which is subjected to recarburization, smelting, pretreatment, spheroidization and inoculation, and then casting is carried out to prepare the component for wind power generation. The invention utilizes the characteristics of high purity and high rolling rate of the pure A3 stalloy to produce components for wind power generation, effectively utilizes waste steel discs, turns waste into treasure, solves the technical problem of changing steel into nodular cast iron, greatly reduces the production cost of nodular cast iron and increases economic efficiency; at the same time, the component for wind power generation produced by the invention has the characteristics of high toughness, high ferrite content, high spheroidization rate and good low temperature performance, and has V-notch impact en
