Manufacturing method of high carbon steel wire rod excellent in mechanical peeling property of scale

摘要

The present invention relates to a method for producing a high carbon steel wire rod, which, after hot rolling at the time of producing a high carbon steel wire rod, controls a proper laying head temperature and a strict cooling rate to maintain excellent mechanical properties and microstructure, It is an object of the present invention to provide a high carbon steel wire rod excellent in mechanical peelability.;The present invention relates to a method for producing a high carbon steel wire rod containing 0.4 to 1.2% by weight of carbon (C), characterized in that the cooling starting temperature after hot rolling is 850-900C and the average cooling rate The cooling rate from 680C to 200C was cooled to 15-25C / sec based on the cooling rate at the moment of passing through 680C, so that the temperature of the FeO layer And a method for producing a high-carbon steel wire rod excellent in mechanical peelability of scale by keeping the thickness uniformly at 10-15 .
