METHOD FOR MANUFACTURING STEEL WIRE FOR REINFORCEMENT OF RUBBER ARTICLE, DEVICE FOR MANUFACTURING THE SAME, STEEL CORD FOR REINFORCEMENT OF THE RUBBER ARTICLE, AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a steel wire for reinforcement of rubber capable of obtaining the steel wire having high strength and excellent in ductility by devising a final wire drawing process in manufacturing the steel wire using a wire rod of a high carbon steel.;SOLUTION: In a method for manufacturing the steel wire for reinforcement of a rubber article where final wire drawing is applied to a high carbon steel wire after plating processing, the final wire drawing includes dry wire drawing composed of a plurality of stages at a front stage, and wet wire drawing is carried out after the dry wire drawing. In the wet wire drawing, an area reduction rate of each pass is gradually reduced at a rear stage.;COPYRIGHT: (C)2012,JPO&INPIT
