The invention discloses an oil-quenched and tempered steel wire production line using a heated air medium to replace a traditional lead medium and an oil-quenched and tempered steel wire production process. The overall structure of the production line is composed of five parts which are a tension pay-off device, a heating furnace, an oil quenching tank, an air tempering furnace and a take-up machine, the air tempering furnace mainly comprises a tempering furnace, an in-furnace stainless steel pipe, a heating electric furnace wire, a thermocouple and the like, and the manufacturing method mainly comprises tempering furnace temperature, steel wire running speed, wire channel arrangement, a fine adjustment method, a mechanical property control method and the like. In combination with the purposes of energy conservation, emission reduction, environmental protection and high efficiency, a design idea that the steel wire is heated in a medium-high temperature heating pipe mode and tempered in a hot air medium is pr
