The invention discloses an electric-arc-type smelting furnace which comprises a furnace body. Feeding inlets are both formed in the two ends of the top of the furnace body, and discharging outlets areboth formed in the two ends of the bottom of the furnace body. A cooling layer is arranged on the inner wall of the furnace body. A vertical electrode set is arranged inside the furnace body. A clamping device is arranged at the top end of the electrode set. A power device is arranged at the top end of the clamping device. The power device is arranged outside the top of the furnace body. A smelting pond is arranged at the bottom of the inside of the furnace body, and the bottom of the smelting pond communicates with the discharging outlets. Graphite is arranged on the side wall and the bottomof the smelting pond. Transmission shafts are both arranged at the two sides of the outside of the furnace body and are connected with driving devices. According to the electric-arc-type smelting furnace, an electrode stem and a material make contact with each other to be reacted, the phenomenon that a traditional external high-temperature smelting method is adopted in the material, so that the material makes contact with the outside air to be reacted easily is avoided, and the performance influence on smelting metal is reduced; and the furnace body can rotate up and down through the drivingdevices and the transmission shafts; a newly-added material and the original material are fully mixed, and the reacting speed of the electrode set and the metal material is increased.
