CA 2058470
The fine steel wire according to the present invention has a high strength and high toughness, which is used as a rubber reinforcing material for a belt cord or tire cord, or as missile wires. Such a fine steel wire can be obtained by drawing a wire rod for a fine steel wire properly adjusted in its composition and structure, while applying working strain such that the total reduction of area in the final wire drawing step becomes 95% or more.
Fil d'acier fin à haute résistance et à haute ténacité utilisé comme matériau de renforcement du caoutchouc dans des câbles de ceinture de pneu, des câbles à pneu ou des câbles de missiles. Pour obtenir ce fil d'acier, il faut étirer un fil machine dont la composition et la structure sont correctement équilibrées et y appliquer une force de tension, de sorte que la réduction totale de l'aire du fil lors de l'étape d'étirage finale soit de 95 % ou plus.
