The invention discloses a 1080MPa carbide-free bainite/martensite complex-phase finish rolling reinforcement and a production method, and relates to the field of metal material processing. The finishrolling reinforcement is prepared from the following chemical components according to weight percent: 0.23 to 0.27% of C, 1.2 to 1.6% of Si, 2.0 to 3.0% of Mn, 0.3 to 1.0% of Cr, 0.06 to 0.10% of V and the balance of Fe and inevitable impurity elements. The production method comprises the following steps of smelting in a convertor, performing LF refining, continuously casting square billets, heating the square billets, descaling with high-pressure water, rolling, naturally cooling and performing tempering heat treatment. The finish rolling reinforcement has the advantages of low carbon content, high hydrogen embrittlement susceptibility and delayed fracture resistant capability, low yield ratio and high safety factor, and a metallographic structure is a carbide-free bainite/martensite complex-phase structure; the production method has the advantage of simple process.
