As an important application, the performance of the holding furnace directly affects the efficiency and quality of related processes, achieving the goals of energy saving, consumption reduction, improved production efficiency and product quality. The electromagnetic multi-barrel holding furnace is suitable for production scenarios that require simultaneous heating of multiple materials, such as chemical, metallurgical and food industries.
[0003] Electromagnetic multi-barrel heating furnaces use the principle of electromagnetic induction to heat metal containers, generating countless small eddies inside. These eddies cause the metal molecules to move at high speeds and generate heat, thus achieving the purpose of heating.
[0004] When using a heat preservation furnace, an electric current drives a coil, which generates a magnetic field. This magnetic field interacts with the metal container, facilitating the heating and heat preservation of various materials and improving heating quality. However, existing electromagnetic heat preservation furnaces use a single heating source and insulation layer, making it difficult to accurately control the heating temperature and to heat independently.

During heating, the heating mechanism facilitates the improvement of the heating efficiency of the heat preservation furnace, facilitates precise control of the heating temperature, improves the heat preservation effect, reduces energy consumption, facilitates the operation of the operator, and improves the flexibility of use.
[0036] Reference Figure 2 and Figure 3 The heating mechanism includes an insulation layer 6 fixed inside the heating tank 2, a heating coil 4 located inside a fixing sleeve 5, and the heating coil 4 electrically connected to a controller 7. A heating groove 10 is formed inside the heating tank 2, and heat-conducting oil 11 is placed inside the heating groove 10. A control component is provided between the controller 7 and the heating tank 2. The control component includes a temperature sensor 9 fixed to the bottom of the heating tank 2, a display screen 8 fixed to the controller 7, and the controller 7 electrically connected to the temperature sensor 9. The insulation layer 6 is made of extruded polystyrene foam, and the heating coil 4 is arranged in a spiral array.
[0037] When the heat preservation furnace is in use, the heating coils 4 are arranged in a spiral array to facilitate uniform heating of the heating barrel 2, ensuring even heating of the material and improving the heating effect. The heating barrel 2 is then insulated by the insulation layer 6 to reduce heat loss. The insulation layer 6 is made of extruded polystyrene foam, which improves the insulation effect and impact resistance of the barrel. The heat generated by the heating coils 4 is distributed evenly through the heat-conducting oil 11 in the heating tank 10, improving heat transfer efficiency. During heating, the temperature sensor 9 detects the temperature inside the heating barrel 2. When the temperature exceeds the preset value, the temperature sensor 9 feeds back to the controller 7, which controls the heating coils 4 to lower the temperature, facilitating accurate temperature control. The display screen 8 shows the real-time temperatures of multiple heating barrels 2, allowing for independent heating of various materials, improving flexibility and ease of operation.

A ceramic insulation sleeve 14 is also fixed to the fixing sleeve 5, with its upper end contacting the cover plate 3. An insulation coating 16, which is ZS-1 high-temperature resistant heat-insulating coating, is installed inside the heating barrel 2.
[0039] When the heat preservation furnace is in use, the heat conduction column 13 conducts the temperature inside the heating barrel 2, and the heat conduction column 13 conducts the heat into the connecting plate 15. The connecting plate 15 then transfers the heat to other heating barrels 2, improving the overall heating efficiency of multiple heating barrels 2. The insulation sleeve 14 is made of rock wool, which helps to reduce heat loss and facilitates heat transfer. The fixing sleeve 5 is made of ceramic insulation sleeve 14, which further reduces heat loss and facilitates heat preservation. The insulation coating 16 is made of ZS-1 high-temperature resistant heat insulation coating, which improves the heat insulation effect of the heating barrel 2, reduces heat loss, and lowers energy consumption.
[0040] The implementation principle of the electromagnetic multi-barrel heat preservation furnace in this embodiment is as follows: When the heat preservation furnace is in use, the operator opens the cover plate 3, puts the material that needs to be heated and kept warm into the heating barrel 2, closes the cover plate 3, and then starts the heating coil 4, so that the heating coil 4 generates a magnetic field that interacts with the heating barrel 2. The heating barrel 2 is made of stainless steel, which facilitates the heating of the heat preservation furnace.
[0041] When used in the heat preservation furnace, the heating coils 4 are arranged in a spiral array to facilitate uniform heating of the heating barrel 2, ensuring even heating of the material and improving the heating effect. The heating barrel 2 is then insulated by the insulation layer 6 to reduce heat loss. The insulation layer 6 is made of extruded polystyrene foam, which improves the insulation effect and impact resistance of the barrel. The heat generated by the heating coils 4 is distributed evenly through the heat transfer oil 11 in the heating tank 10, improving the heat transfer efficiency. During heating, the temperature inside the heating barrel 2 is detected by the temperature sensor 9. When the temperature exceeds the preset value, the temperature sensor 9 feeds back to the controller 7, which controls the heating coils 4 to reduce the temperature for accurate temperature control. The temperature of multiple heating barrels 2 is displayed in real time on the display screen 8, facilitating independent heating of various materials.
[0042] When the heat preservation furnace is in use, the heat is conducted through the heat conduction column 13 to conduct the temperature inside the heating barrel 2, and then through the heat conduction column 13 to conduct the heat into the connecting plate 15. The connecting plate 15 then transfers the heat to other heating barrels 2, improving the overall heating efficiency of multiple heating barrels 2. The insulation sleeve 14 is made of rock wool, which helps to reduce heat loss and facilitates heat transfer. The fixing sleeve 5 is made of ceramic insulation sleeve 14, which further reduces heat loss and facilitates heat preservation.
