<p>PROBLEM TO BE SOLVED: To provide a melting method of a high carbon steel for wire rod, with which a wire rod having low break occurrence of wire can be formed. SOLUTION: In the melting method of the high carbon steel for wire rod, with which molten high carbon steel composed of 0.5-1.0 wt.% C, 0.15-0.50 wt.% Si, 0.30-0.90 wt.% Mn, <0.020 wt.% P, <0.020 wt.% S and the balance iron with inevitable impurities is charged into a ladle and stirred together with slag whose CaO/SiO2 ratio is adjusted to 1.0-1.5, and slag-metal reaction is executed for secondary refining, REM-containing alloy is added to the slag for the slag-metal reaction.</p> |
