With the development of automobile industry,tire is marching toward lighter,energy-saving and safer,and it has been a trend for steel cord to develope in high strength and ultrahigh-strength.In order to reduce fracture of tire cord,steel cord is producted with bloom casting machine by soft reduction to reduce segregation,with clean steel smelt technology to control inclusion.TMCP of wire cord is improved in Baosteel.With technological advancement,the quality of steel cord has been noticeably raised and ultrahigh-strength has developed successfully.The paper introduces the development of steel cord in Baosteel.
