[0002] In the magnetic material industry, in order to obtain better magnetic material properties, two tempering processes are required. One tempering can improve the plasticity and toughness of the material and enhance properties such as coercivity;

[0003] During the second tempering, the material structure can be made more uniform, the grains can be made more refined, residual stress and dislocations can be eliminated, and the magnetic material properties can be further improved.

[0004] The performance of the above two tempering processes is affected by the cooling rate. The faster the cooling rate, the better the performance of the magnetic material.

[0005] The commonly used tempering furnace in the magnetic material industry is a horizontal single-body heat treatment furnace, with multiple material boxes arranged in the length, width, and height directions.

[0006] However, when the existing magnetic material blocks are cooled by blowing air, there is a certain temperature difference between the inner and outer layer materials, resulting in poor consistency of the material performance. At the same time, due to the small heat dissipation area of each material block on average, the cooling rate is slow, resulting in lower overall performance. Utility Model Content

[0038] The following will Figures 1-4 further describe in detail an air duct structure for magnetic material tempering and cooling and its tempering and cooling device provided by the present application.

[0039] Please refer to Figures 1-4 , which is an air duct structure for magnetic material tempering and cooling provided in the embodiments of the present application, including: a frame 1 with a placement cavity inside, two groups of air duct plate assemblies 2, and two groups of air deflector assemblies 3;

[0040] The two groups of the air duct plate assemblies 2 are respectively assembled on the inner walls of the upper and lower ends of the frame 1 and communicate with the placement cavity. The airflow passing through and entering the air duct plate 21 is divided into multiple strands and evenly blows towards the magnetic material, thereby improving the uniformity of cooling the magnetic material;

[0041] The two groups of the air deflector assemblies 3 are respectively assembled on the outer walls of the upper and lower ends of the frame 1 and correspond to the two groups of the air duct plate assemblies 2 one by one. The opposite sides of the two groups of the air deflector assemblies 3 are respectively communicated with the corresponding air duct plate assemblies 2. By respectively arranging the air deflector assemblies 3 at the upper and lower ends of the frame 1 and connecting them to an external fan, the airflow can blow through the magnetic material from bottom to top and take away the heat of the magnetic material. Compared with the blowing cooling method, the speed of taking away heat by the unidirectional flowing airflow is faster.

[0042] Each of the fairing assemblies 3 is one or more fairings 31. A plurality of the fairings 31 are spaced along the length direction of the frame 1 on its outer wall. An air guiding channel 32 penetrating through the fairing 31 vertically is provided inside the fairing 31. The air guiding channel 32 is communicated with the air duct plate assembly 2. Wherein, when one fairing 31 is provided, the projected area of the fairing 31 on the ground is larger than the projected area of the magnetic material disk on the ground and smaller than the projected area of the frame 1 on the ground. When a plurality of fairings 31 are provided, the sum of the projected areas of the plurality of fairings 31 on the ground is larger than the projected area of the magnetic material disk on the ground and smaller than the projected area of the frame 1 on the ground. Thus, air flow can enter the frame 1 from the fairing 31 located below the frame 1, and after heat exchange, it can be dissipated from the fairing 31 above the frame 1.

[0043] In this embodiment, the inner wall of the fairing 31 is coated with high-temperature resistant paint. The fairing 31 is fixed to the frame 1 by welding or bolts. Wherein, in this application, different air blowing methods are used for different positions of the magnetic material for air cooling, and the data analysis diagram of its temperature change is as Figure 3 shown.

[0044] Each of the air duct plate assemblies 2 is one or more air duct plates 21. A plurality of the air duct plates 21 are spaced along the length direction of the frame 1 on one side of its inner wall. A ventilation pipe assembly 22 is provided on the other side of each air duct plate 21. The ventilation pipe assembly 22 is communicated with the corresponding fairing 31. When the number of fairings 31 inside each fairing assembly 3 is one, correspondingly, the number of air duct plates in each air duct plate assembly 2 is also set to one so that it can be connected to the fairing 31, enabling the air flow to be evenly blown onto the magnetic material plate after being split by the air duct plate 21, making its cooling effect more uniform. Similarly, when the number of fairings 31 inside each fairing assembly 3 is multiple, correspondingly, the number of air duct plates in each air duct plate assembly 2 is also set to multiple.

[0045] In this embodiment, the surface of the air duct plate 21 can also be coated with high-temperature resistant paint. The air duct plate 21 is fixed to the inner wall of the frame 1 by bolts. Wherein, in this application, air cooling with or without the air duct plate 21 is performed on different positions of the magnetic material, and the data analysis diagram of its temperature change is as Figure 4 shown.

[0046] The ventilation pipe assembly 22 includes two sets of hollow pipe members 221. The two sets of hollow pipe members 221 are respectively arranged on the left and right sides of the air duct plate 21. When the air flow passes through the air duct plate 21, the air flow can be split into the two sets of ventilation pipe assemblies 22, thereby realizing the split in the left and right directions and improving the cooling uniformity of the magnetic material.

[0047] Each set of the hollow tubes 221 includes a plurality of hollow tubes 221. The plurality of hollow tubes 221 are arranged at intervals in the front-rear direction on the air duct plate 21 and communicate with the flow guide cover 31. When the air flow passes through each set of hollow tubes 221, the diversion in the front-rear direction can be realized, thereby further improving the cooling uniformity of the magnetic material. Among them, the interval between the plurality of hollow tubes 221 is determined according to the requirements of the actual working conditions. In this application, according to the simulation experiment data, for the final temperature of the magnetic material after cooling, the temperature near the front and rear ends of the frame 1 is lower than the temperature of the magnetic material located in the middle. Therefore, when the plurality of hollow tubes 221 are arranged in the front-rear direction, the interval between the hollow tubes 221 located in the middle of the frame 1 can be smaller than the interval between the hollow tubes 221 located at both ends of the frame 1.

[0048] In this embodiment, the hollow tube 221 can be assembled on the flow guide plate by threads or integrally formed with the flow guide plate.

[0049] It further includes a plurality of rollers 4. The plurality of rollers 4 are arranged on the outer wall of the lower end of the frame 1 along the length direction of the frame 1 and are distributed on the left and right sides of the flow guide cover 31. Among them, the rollers 4 can be arranged on the guide rails, so as to facilitate the user to drive the device to move along the track.

[0050] In this embodiment, a plurality of rollers can also be provided. The plurality of rollers are arranged on the outer wall of the lower end of the frame 1 along the length direction of the frame 1. By using the rollers to replace the rollers 4, the device can move conveniently on the ground.

[0051] It further includes a plurality of fixing brackets 5. The plurality of fixing brackets 5 are arranged on the outer walls of the left and right sides of the frame 1 along the length direction of the frame 1. The fixing brackets 5 are fixed to external equipment or walls through fixing parts such as bolts, so that the device can be more stable when air-cooling the magnetic material.

[0052] It further includes a plurality of support rods 6 extending in the left-right direction. The plurality of support rods 6 are arranged at intervals along the length direction of the frame 1 and are used for placing the material trays. According to the size of the trays, a plurality of support rods 6 arranged at intervals are assembled, so that the trays can be suspended and erected, and while the trays can be stably placed, the hollow tubes 221 will not be blocked, and the hollow tubes 221 can uniformly contact the lower end of the trays.

[0053] In this embodiment, a plurality of groups of through holes 11 are symmetrically opened on the left and right sides of the frame 1, and the support rods 6 are inserted at the through holes 11, so that the support rods 6 penetrate through the through holes 11 on both sides. The connection manner between the support rods 6 and the frame 1 can be threaded connection or welding at the through holes 11.

[0054] The second object of the present utility model is to provide a magnetic material tempering and cooling device.

[0055] In order to achieve the above-mentioned purpose, the technical solution of the present application is as follows: a magnetic material tempering cooling device includes an air duct structure for magnetic material tempering cooling.

[0056] It also includes a fan and a heat exchanger (not shown in the figure), the air outlet of the fan is connected to the air inlet of the heat exchanger, the air inlet of the fan is connected to the air guide cover 31 located on the lower end surface of the frame 1 through a conduit, and the air outlet of the heat exchanger is connected to the air guide cover 31 located on the upper end surface of the frame 1 through a conduit. When the magnetic material needs to be air-cooled, the fan is turned on, and the air flow of the fan enters the frame 1 from the air guide cover 31 below the frame 1. After the cold air takes away the heat of the magnetic material, it returns to the heat exchanger above the frame 1 for heat exchange, and the cold air after heat exchange is re-injected into the frame 1 to continue to dissipate heat.

[0057] Through the above technical solution, the fan is used to drive the air flow into the frame 1, and the air flow is guided to be diverted through the air duct plate 21 and then blown through the magnetic material in one direction, thereby improving the speed and uniformity of cooling the magnetic material.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
