Development and Production of Hot Rolled Steel Strip for Manufacture of Mechanical Joint Flat Washers
Aiming at the upgrading requirements of high strength,high wear resistance,corrosion resistance,fatigue resistance and other properties of hot-rolled steel strip for manufacturing of high-quality mechanical connection flat washers,by optimizing composition design,optimizing argon blowing system during smelting process and collaborative control of tundish superheat,selecting appropriate pouring temperature and billet pulling rate,precise control of C,S and other segregation elements is achieved.To ensure the uniform structure of the steel strip thickness direction,the high quality carbon hot rolled steel strip for flat washers has been successfully developed.The obtained steel strip thickness specification is 4.5-10 mm,uniform organization,mainly pearlite plus ferrite,product performance meets the wind power,railway,steel structure,bridge,subway,automobile and other industries for high-quality flat gasket manufacturing requirements,with strong industrial practice and promotion value.
