The invention discloses a high-temperature box-type resistance furnace without a heater at the furnace bottom, relates to the technical field of heat treatment equipment, and solves the technical problems that a trolley-type resistance furnace needs a large space for overhauling and cannot well preserve heat. The high-temperature box-type resistance furnace is characterized in that the interior of a furnace body is sealed through a structural member, and air tap pieces are arranged on the left side and the right side of the furnace body; the upper side of the furnace body is sealed through a heat insulation plate, the furnace body is sealed through an air tap piece on the left side, the right side of the furnace body is sealed through a brick wall, the lower side of the furnace body is sealed through a brick wall, a heat insulation plate is attached to the lower side of the brick wall on the lower side of the furnace body, and a resistance heating wire is arranged on the furnace wall in the furnace body. The resistance heating wire is wound into a corrugated shape and is arranged on a porcelain nail hanging piece arranged on the furnace wall; the heat treatment furnace is used for heat treatment of industrial materials and has the advantages of small site space required by overhaul and good heat preservation.
