Steel wire rod for flattened steel wire without recrystallization annealing process and production method thereof

The invention relates to a steel wire rod for a flattened steel wire without a recrystallization annealing process and a production method thereof. The steel wire rod is prepared from the following components in percent by mass: 0.58-0.68% of C, 0.15-0.25% of Si, 0.40-0.60% of Mn, less than or equal to 0.010% of P, less than or equal to 0.010% of S, less than or equal to 0.0040% of N and the balance Fe and inevitable impurities. By producing the steel wire rod for the flattened steel wire without the recrystallization annealing process, the invention provides the dedicated steel wire rod for the flattened steel wire for a wire rod product industry. The steel wire rod has the characteristics of being high in degree of purity of steel and uniform in component and texture, has good plasticityand toughness without the recrystallization annealing process and has obvious social and economical benefits. 本发明涉及一种免除再结晶退火工序的压扁钢丝用盘条及其生产方法，该盘条成分及质量百分比为：C 0.58～0.68％，Si 0.15～0.25％，Mn 0.40～0.60％，P≤0.010％，S≤0.010％，N≤0.0040％，其
