Production of high carbon steel rod with a thin wire

The invention provides a high carbon steel wire rod for producing thin steel wire. The wire rod comprises the following chemical components, by weight, 0.6%-0.88% of [C], 0.1%-1.0% of [Si], 0.3%-1.0% of [Mn], less than or equal to 0.015% of [P], less than or equal to 0.010% of [S], less than or equal to 0.020% of [P+S], less than or equal to 0.004% of [N], less than or equal to 0.002% of [O], less than or equal to 0.002% of [Al], less than or equal to 0.002% of [Ti], less than or equal to 0.001% of [Mg], less than or equal to 0.1% of other inevitable impurities, and the balance of iron. With the present invention, the high carbon steel wire rod provided by the present invention has characteristics of reasonable component designing and excellent processing performance; the foreign substances in the wire rod have low melting point, and elongate along a rolling direction during a hot rolling process, and have a length-width ratio more than 3, such that the wire breaking ratio during the steel wire processing is reduced by 16-28%.
