Description
Technical Field
[0001] The utility model relates to the field of heating equipment, in particular to an energy-saving heating device for non-magnetic steel forging. Background Art
[0002] Non-magnetic steel refers to a low-magnetic steel material that basically does not generate magnetic induction under the action of a magnetic field. Non-magnetic steel is widely used in the fields of electric power, rail transit, construction, oil drilling, and national defense and military. In the processing of non-magnetic steel, forging is a processing method that weakens the voids and cavities inside the non-magnetic steel, can improve the internal structure of the non-magnetic steel, and improve the mechanical properties of the metal. Before forging non-magnetic steel, it is necessary to heat the non-magnetic steel. Commonly used heating furnaces include gas heating furnaces and electric furnaces, etc. When the existing heating furnaces discharge and feed materials, if the door is opened too large, a large amount of heat will be lost, resulting in waste of thermal energy. Therefore, it is particularly necessary to develop an energy-saving heating device for non-magnetic steel forging that can reduce heat loss. Summary of the Invention
[0003] The purpose of the utility model is to provide an energy-saving heating device for non-magnetic steel forging, which has the function of reducing heat loss and saving energy.
[0004] The adopted technical solution is as follows:
[0005] An energy-saving heating device for non-magnetic steel forging includes a furnace body. The furnace body includes a heating chamber and a blanking chamber. A first heat-insulating door is hinged to the blanking chamber. A second heat-insulating door is hinged between the heating chamber and the blanking chamber. A sliding door is slidably arranged in the middle of the second heat-insulating door. A plurality of electric heating tubes are vertically arranged on the inner wall of the heating chamber. A feeding cart is arranged in the heating chamber. A steel cable is connected to the lower end of the feeding cart and extends into the blanking chamber. A groove is formed on the upper end surface of the feeding cart, and an extension plate is slidably arranged in the groove.
[0006] Preferably, a lifting receiving table is arranged in the blanking chamber.
[0007] Preferably, a guide wheel is arranged below the lifting receiving table, and the steel cable passes below the guide wheel and is fixedly connected to the lifting receiving table upward.
[0008] Preferably, a push rod is horizontally slidably arranged on the first heat-insulating door, and a graphene handle is arranged at the end of the push rod.
[0009] Preferably, a guide rail corresponding to the feeding cart is arranged on the lower end surface of the heating chamber.
[0010] Compared with the prior art, the beneficial effects are as follows:
[0011] When the present utility model heats a non-magnetic steel with a relatively small volume and needs to load and unload materials, only the sliding door needs to be opened to place the non-magnetic steel on the feeding cart or take it out. The opening is relatively small, and the heat loss is relatively small. When heating a non-magnetic steel with a relatively large volume and needs to load and unload materials, the second heat-insulating door is opened, and the non-magnetic steel on the feeding cart is conveyed into the blanking chamber. Heat exchange occurs between the heating chamber and the blanking chamber. Compared with heat exchange with the outside world, the heat loss is relatively small, and energy is saved.

[0016] The following further describes the present utility model in combination with specific embodiments, as Figures 1 to 3 shown:
[0017] Embodiment 1: An energy-saving heating device for forging non-magnetic steel, including a furnace body 1. The furnace body 1 includes a heating chamber 2 and a blanking chamber 3. A first heat-insulating door 6 is hinged to the blanking chamber 3. A second heat-insulating door 4 is hinged between the heating chamber 2 and the blanking chamber 3. The second heat-insulating door 4 separates the heating chamber 2 and the blanking chamber 3. A sliding door 5 is slidably arranged in the middle of the second heat-insulating door 4. The size of the sliding door 5 is relatively small and is suitable for the entry and exit of non-magnetic steel with a relatively small size.
[0018] A plurality of electric heating tubes 7 are vertically arranged on the inner wall of the heating chamber 2. The electric heating tubes 7 heat the inside of the heating chamber 2, and the non-magnetic steel is heated by high temperature. A feeding cart 8 is arranged in the heating chamber 2. The lower end of the feeding cart 8 is connected with a steel cable 10 extending into the blanking chamber 3. In the blanking chamber 3, the feeding cart 8 is pulled close to the second heat-insulating door 4 by pulling the steel cable 10. A groove is formed on the upper end surface of the feeding cart 8, and an extension plate 11 is slidably arranged in the groove. The extension plate 11 is pulled to extend to the sliding door 5 so as to facilitate taking out the non-magnetic steel on the extension plate 11 from the sliding door 5.
[0019] When heating a large-sized non-magnetic steel and it is necessary to load and unload materials, open the second heat-insulating door, and convey the non-magnetic steel on the feeding cart 8 into the unloading bin 3. Heat exchange occurs between the heating bin 2 and the unloading bin 3. Compared with heat exchange with the outside world, the heat loss is smaller, saving energy.
[0020] Embodiment 2: An energy-saving heating device for forging non-magnetic steel, comprising a furnace body 1. The furnace body 1 includes a heating bin 2 and an unloading bin 3. The unloading bin 3 is hinged with a first heat-insulating door 6. A second heat-insulating door 4 is hinged between the heating bin 2 and the unloading bin 3. The second heat-insulating door 4 separates the heating bin 2 and the unloading bin 3. A sliding door 5 is slidably arranged in the middle of the second heat-insulating door 4. The size of the sliding door 5 is smaller and is suitable for the entry and exit of non-magnetic steel with a smaller size.
[0021] A plurality of electric heating tubes 7 are vertically arranged on the inner wall of the heating bin 2. The electric heating tubes 7 heat the interior of the heating bin 2, and use high temperature to heat the non-magnetic steel. A feeding cart 8 is arranged in the heating bin 2. A guide rail 9 corresponding to the feeding cart 8 is arranged on the lower end surface of the heating bin 2. A steel cable 10 extending into the unloading bin 3 is connected to the lower end of the feeding cart 8. In the unloading bin 3, the feeding cart 8 is pulled close to the second heat-insulating door 4 by pulling the steel cable 10. A groove is formed on the upper end surface of the feeding cart 8. An extension plate 11 is slidably arranged in the groove. Pull the extension plate 11 so that the extension plate 11 extends to the sliding door 5, thereby facilitating the removal of the non-magnetic steel on the extension plate 11 from the sliding door 5.
[0022] When heating a large-sized non-magnetic steel and it is necessary to load and unload materials, open the second heat-insulating door 4, and convey the non-magnetic steel on the feeding cart 8 into the unloading bin 3. Heat exchange occurs between the heating bin 2 and the unloading bin 3. Compared with heat exchange with the outside world, the heat loss is smaller, saving energy. An elevating receiving platform 12 is arranged in the unloading bin 3. A guide wheel 13 is arranged below the elevating receiving platform 12. The steel cable 10 passes below the guide wheel 13 and is fixedly connected to the elevating receiving platform 12 upward. The elevating receiving platform 12 is raised, thereby pulling the feeding cart 8 to move through the steel cable 10. A push rod 14 is horizontally slidably arranged on the first heat-insulating door 6. A graphene handle 15 is arranged at the end of the push rod 14. Push the push rod 14 to move the feeding cart 8 in the heating bin 2.
[0023] The specific working process is as follows: When heating a small-sized non-magnetic steel and it is necessary to load and unload materials, only need to open the sliding door 5 to place or take out the non-magnetic steel on the feeding cart 8. The opening is small, and the heat dissipation is small. When heating a large-sized non-magnetic steel and it is necessary to load and unload materials, open the second heat-insulating door, and convey the non-magnetic steel on the feeding cart 8 into the unloading bin 3. Heat exchange occurs between the heating bin 2 and the unloading bin 3. Compared with heat exchange with the outside world, the heat loss is smaller, saving energy.
