The invention discloses a steel wire continuous tempering electric heating furnace. The steel wire continuous tempering electric heating furnace comprises a bottom plate, a furnace body, a control panel, a feed port, a discharge port, a tempering mechanism, a limiting mechanism, a longitudinal cleaning mechanism and a transverse cleaning mechanism, wherein the furnace body is fixedly connected toone end of the top of the bottom plate; the control panel is fixedly installed on one side of the furnace body; the feed port is formed in one side, adjacent to the control panel, of the outside of the furnace body; and the discharge port is formed in one side, away from the feed port, of the furnace body. The steel wire continuous tempering electric heating furnace is impact in structure, simpleand convenient to operate, high in practicability, and capable of cleaning steel wires with impurities in advance through the cooperation of the longitudinal cleaning mechanism and the transverse cleaning mechanism, so that the steel wires are prevented from bringing the impurities to the interior of the heating furnace, not only is the workload of operators reduced, but also the heat loss causedby frequent opening of the heating furnace is avoided; and in addition, through arranging the tempering mechanism in the furnace, hot air in the furnace can be circularly heated, so that the temperingand heating effect is greatly improved.
