PURPOSE: A method for drawing a steel wire rod used for manufacturing a steel wire with excellent torsional property and high strength is provided to obtain a high-strength wire rod within a range not to decrease the tensile strength by controlling the approach to a drawing dice and the drawing speed.;CONSTITUTION: A method for drawing a steel wire rod used for manufacturing a steel wire with excellent torsional property and high strength is as follows. The approach angle to a drawing dice is 6~9°. The drawing speed is set less than 30m/min. A steel wire is composed of C 0.82~0.95 weight%, Si 0.8~0.15 weight%, Mn 0.2~0.8 weight%, Cr 0.1~0.5 weight%, S 0.015 weight% or less, P 0.015 weight% or less, and the rest Fe and other inevitable impurities.;COPYRIGHT KIPO 2010
