description The utility model relates to a heating device and specifically discloses a locally heating furnace for forge pieces. The furnace is characterized by comprising a cylindrical furnace shell (3), a side wall thermal insulation layer (2) laid on the inner side of the furnace shell (3), a side wall flame retardant layer (4) covering the inner side of the side wall thermal insulation layer (2), a plurality of annular support sheets (6) fixed on the inner side of the side wall flame retardant coating (4) from top down at equal distance, annular resistance wires (5) fixed on the annular support sheets (6) and acting as heat sources, a bottom thermal insulation layer (9) on the furnace bottom, a bottom flame retardant layer (8) laid on the bottom thermal insulation layer (9) and two semi-circular furnace covers (1) covering the heating furnace. A gasket (7) is disposed in the center of the upper surface of the bottom flame retardant layer (8). The middle parts of the semi-circular furnace covers (1) are provided with semi-circular gaps. The two semi-circular furnace covers (1) form a complete round top cover and the semi-circular gaps in the two semi-circular furnace covers (1) form a round hole.
