HIGH CARBON STEEL WIRE PRODUCTION METHOD

PROBLEM TO BE SOLVED: To provide a high carbon steel wire production method for producing a high carbon steel wire of high quality by dry type wire drawing while seizure to a die is easily and securely prevented. SOLUTION: In the production method, when a high carbon steel wire rod A comprising, by mass, 0.6 to 1.1% C, 0.1 to 1.5% Si, 0.3 to 1.0% Mn, ≤0.02% P and ≤0.02% S is continuously passed through a plurality of passes each provided with a die 4 and a cooling block 5 at the poststage thereof, and is subjected to wire drawing, at least one selected from the total of the dies 4, the combination of the reduction of area in each die 4, and a wire drawing rate is regulated so as to satisfy inequality P=äΣ(Tk×rk)}/n≤20.4, wherein, Tkdenotes the temperature [°C] of the lower part at the side face in the cooling block 5 of the k-th stage measured by a radiation thermometer 6; rkdenotes the reduction of area [%/100] in the die 4 of the k-th stage; n denotes the total of the dies 4; and Σ denotes the total of the stages.
