Method for producing steel wool steel by adopting bidirectional cotton scraping process

The method for producing the steel wool steel by adopting the two-way cotton scraping process comprises the working procedures of wire rod inspection, drawing, crack measurement and cotton scraping; a steel wire is obtained after the wire rod is drawn, the steel wire is wound on a curling wheel, scraped steel wool steel is collected to serve as a production raw material of steel wool after the cotton scraping process of a cotton scraper, and remaining tailings serve as waste steel to be recycled; wherein the cotton scraping knife is used for symmetrically and longitudinally planing the inner side and the outer side of the steel wire in a two-way alternate cotton scraping mode or a two-way simultaneous cotton scraping mode, the single-time scraping depth of the inner side of the steel wire by the cotton scraping knife is the same as the corresponding scraping depth of the outer side of the steel wire by the cotton scraping knife, and the accumulated cotton scraping depth of the inner side or the outer side of
