| titleOfInvention | High strength steel cord and manufacturing method |
| abstract | The present invention is to control the carbon content and the number of draw times according to the material selection without changing the physical properties, to impart plastic deformation to the filament and stranded the filaments in an open structure, to improve the tensile strength and penetration of the rubber A high strength steel cord and a method of manufacturing the same.n n n After the primary wire processing of the wire rod with a diameter of 5.5 mm and the carbon content of 0.8 to 0.9% to have a diameter of 1.0 to 2.5 mm, the plated heat treatment was performed at a temperature of approximately 900 to 1100 ° C. Is coated with brass, and the plated wire rod is drawn again at least once to obtain a tensile strength of 360 to 420 kg / mm 2, and the diameter of the filament is reduced. After plastic deformation, twisted and spaced apart from each other to have an open dog structure.n n n According to the present invention, since the present invention can satisfy the sufficient rigidity in a small amount compared to the existing steel cord, it is possible to not only improve the weight and rolling resistance of the tire, but also reduce the cost and improve the fuel efficiency. Haven n n In addition, since the filament diameter is thicker than the conventional one, the stiffness is improved and the tire handling characteristics are excellent. In particular, the filament has a very useful advantage of excellent rubber permeability and improved rubber adhesion rate because the open structure is spaced between the filaments. |
