Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, specifically to a heating mechanism for an annealing furnace used in copper strip annealing. Background Technology

[0002] The copper strip annealing process is a heat treatment process designed to improve the physical and machinability of copper strips. During annealing, the copper strip is heated to a certain temperature and then slowly cooled to eliminate internal stress and restore the desired properties. This process affects the crystal structure of the copper strip, thereby improving its ductility and machinability.

[0003] Existing patent application number: 202123373868.0 A copper strip support and positioning device for an annealing furnace for irregularly shaped copper strips, comprising a support tube fixedly welded to the upper middle part of a bracket, the copper strip being disposed above the bracket, a support ring being disposed in the middle of the copper strip, the support tube being disposed through the middle of the support ring, a circular hole being disposed in the lower part of the inside of the support tube, and a fixed shaft being fixedly welded to the top of the support tube.

[0004] The aforementioned patent describes an annealing furnace used in the copper strip annealing process. The annealing furnace uses heating wires as heating elements and requires regular maintenance and upkeep during use to ensure its safe and efficient operation. However, the heating wires are installed on the inner wall of the annealing furnace channel and are difficult to disassemble, making cleaning and maintenance difficult. If carbon deposits on the surface of the heating wires are not treated in time, they may cause short circuits and affect normal use. The installation structure of the heating wires in the annealing furnace can be improved to make them easier to disassemble and maintain. Utility Model Content

[0005] The purpose of this invention is to provide a heating mechanism for an annealing furnace used in copper strip annealing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a heating mechanism for an annealing furnace used in copper strip annealing, comprising an annealing furnace body, a heating channel, and a detachable heating mechanism. The annealing furnace body has a heating channel running through its interior, front to back. The detachable heating mechanism is housed within the heating channel. The detachable heating mechanism includes a carrier plate, a guide groove, a guide rail, a first mounting hole, a second mounting hole, a refractory plate, a heating wire, and a power cord. Carrier plates are mounted on both the upper and lower inner sides of the heating channel, and the left and right sides of the carrier plates are symmetrical. The heating channel has a guide groove and four guide rails symmetrically distributed on the left and right side walls. The guide groove and the guide rail surfaces are fitted together to establish a sliding connection between the carrier plate and the heating channel. The carrier plate has a first mounting hole on both the front and rear sides, and the heating channel has a second mounting hole on both the upper and lower sides of both the front and rear sides. The first and second mounting holes are locked together with bolts. The surface of the carrier plate is covered with a fire-resistant board, and a heating wire is installed on the surface of the fire-resistant board. The power cord of the heating wire extends outward from the corner of the fire-resistant board.

[0007] Preferably, both the carrier plate and the guide rail are made of heat-resistant steel.

[0008] Preferably, the fire-resistant board is made of aluminum silicate.

[0009] Preferably, the power cord surface is equipped with a heat insulation sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention features a detachable heating mechanism inside the heating channel. By removing the connecting bolts between mounting holes one and two, the carrier plate is restored to its movable state. The carrier plate can then be pushed horizontally and slid outward from the inside of the heating channel along the guide rail. This allows for maintenance of the heating wires installed on the refractory plate without having to perform maintenance within the limited space of the heating channel, greatly facilitating cleaning and maintenance work.

[0016] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0017] Please see Figure 1 This utility model provides a heating mechanism for an annealing furnace for copper strip annealing, including an annealing furnace body 1, a heating channel 2 and a detachable heating mechanism 3. The heating channel 2 is arranged through the front and back of the annealing furnace body 1, and the detachable heating mechanism 3 is arranged inside the heating channel 2.

[0018] Please see Figure 2-3 This utility model provides a heating mechanism for an annealing furnace used in copper strip annealing. The detachable heating mechanism 3 includes a carrier plate 31, guide grooves 32, guide rails 33, a first mounting hole 34, a second mounting hole 35, a refractory plate 36, a heating wire 37, and a power cord 38. The carrier plate 31 is mounted on both the upper and lower sides of the inner side of the heating channel 2. Guide grooves 32 are symmetrically opened on the left and right sides of the carrier plate 31. Four guide rails 33 are symmetrically distributed on the left and right side walls of the heating channel 2. The guide grooves 32 and the guide rails 33 are fitted and inserted into each other, so that the carrier plate 31 and the heating channel 2 are connected. The carrier plate 31 is slidably connected and can slide outward from the inside of the heating channel 2 along the guide rail 33. The carrier plate 31 has a first mounting hole 34 on both the front and rear sides. The heating channel 2 has a second mounting hole 35 on both the upper and lower sides of both the front and rear sides. The first mounting hole 34 and the second mounting hole 35 are locked and fixed with bolts, thereby locking and fixing the carrier plate 31 to the inside of the heating channel 2. The surface of the carrier plate 31 is covered with a fire-resistant board 36. A heating wire 37 is installed on the surface of the fire-resistant board 36. The power line 38 of the heating wire 37 extends outward from the corner of the fire-resistant board 36.

[0019] To further explain, both the carrier plate 31 and the guide rail 33 are made of heat-resistant steel. The high-temperature strength, hardness, toughness and plasticity of the heat-resistant steel can remain stable at high temperatures, so as to ensure that the carrier plate 31 and the guide rail 33 can work for a long time in a high-temperature environment.

[0020] To further explain, the refractory board 36 is made of aluminum silicate board, which can withstand extremely high temperatures and is usually used as the wall lining of heating furnaces, so that the refractory board 36 can work stably as the carrier of the heating wire 37.

[0021] To further explain, the power cord 38 is equipped with a heat insulation sleeve on its surface to ensure stable operation.

[0022] The working principle is as follows:

[0023] First, before use, connect the power cord 38 to an external control device to control the operating temperature of the heating wire 37.

[0024] Second, during use, the copper strip to be processed is passed through the annealing furnace body 1 from the inside of the heating channel 2. During this process, the heating wire 37 is energized and heats up to heat the copper strip passing through the heating channel 2, thereby achieving the heating treatment of the copper strip.

[0025] Third, after a period of use, carbon deposits easily form on the surface of the heating wire 37, producing impurities. If these are not cleaned in time, they can easily cause short circuits and affect normal use. By setting a detachable heating mechanism 3 inside the heating channel 2, first confirm that the inside of the heating channel 2 has been completely cooled to ensure safe operation. Then, remove the connecting bolts of the first mounting hole 34 and the second mounting hole 35 to restore the carrier plate 31 to its movable state. The carrier plate 31 can then be pushed horizontally to slide outward from the inside of the heating channel 2 along the guide rail 33. This allows for maintenance of the heating wire 37 installed on the refractory plate 36 without having to perform maintenance in the space-constrained heating channel 2, greatly facilitating the cleaning and maintenance work.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
