Abstract

The invention discloses an annealing furnace internally heated uniformly and externally insulated, and belongs to the technical field of heat treatment equipment. The annealing furnace comprises a box body, the inner wall of the box body is provided with a sliding groove, the box body is internally and fixedly provided with a bearing device, the exterior of the bearing device is provided with a heating device, the inner wall of the heating device is movably connected with the outer wall of the bearing device, a rotating ring is arranged in the heating device, one end of a connecting plate is fixedly connected with the outer wall of the rotating ring, a sliding column is arranged at the other end of the connecting plate, the outer wall of the sliding column is slidably connected with the inner wall of the sliding groove, a mounting block is fixedly mounted at the end, away from the sliding groove, of the connecting plate, and a fixing protruding block is fixedly connected to the outer wall of the mounting block. According to the annealing furnace internally heated uniformly and externally insulated, a workpiece can be uniformly heated in the box body through the heating device, the quality of the workpiece is improved, a circulation device can accelerate flowing of air in the box body, heat transfer in the heating process is promoted, and uniform heating of the workpiece is facilitated.

Description

technical field [0001] The invention belongs to the technical field of heat treatment equipment, and in particular relates to an annealing furnace with uniform internal heating and external heat insulation. Background technique [0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; reduce residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure, and eliminate structure defects. To be precise, annealing is a heat treatment process for materials, including metal materials and non-metal materials. Moreover, the purpose of annealing new materials is similar to that of traditional metal annealing. Annealing furnaces are classified according to heat sources into electric furnaces, coal-fired annealing furnaces, oil-fired annealing fur...
