摘要： A process for manufacturing a high tensile steel wire, characterized by comprising the steps of pre-cooling a hot-rolled steel rod to a temperature between 750.degree.-900.degree. C. by means of a cooling apparatus provided between a group of intermediate rolling mills and a group of finishing rolling mills in a hot rolling line for steel rod, finishing rolling the thus pre-cooled steel rod, quenching the hot rolled steel rod to a temperature of 700.degree. C. or lower to provide a supercooled austenite phase, then finishing-cooling the thus quenched rod to provide martensite, and drawing the resulting steel rod with roller dies without descaling is disclosed.
