Description

Technical Field

[0001] The invention belongs to the technical field of heat treatment, and in particular relates to a rotary annealing device and a continuous temperature control system and method thereof. Background Art

[0002] In the field of material processing, annealing is a key heat treatment process, which is widely used in a variety of materials such as metals, glass, semiconductors, etc., aiming to improve the microstructure and performance of materials, such as eliminating stress, increasing the toughness of materials, improving conductivity, etc. Traditional annealing methods include box annealing furnaces, pit annealing furnaces, etc. These traditional annealing equipment usually adopts a static heating method, that is, the material to be annealed is placed in a fixed position, and the entire furnace cavity is heated by a heating element, so that the material is kept in a specific temperature environment for a period of time to achieve the annealing effect.

[0003] During the static annealing process, the relatively fixed position of the heating source can easily lead to uneven temperature distribution in the furnace chamber. The temperature of the area close to the heating element rises faster and higher, while the temperature of the area far from the heating element rises slowly, which may cause inconsistent annealing effects in different parts of the material and affect the stability of product quality. For large or complex-shaped materials, this temperature unevenness problem is more prominent, which may cause thermal stress inside the material and even local performance deterioration.

[0004] Some research and applications have begun to try to use a rotary structure to improve the temperature uniformity problem during the annealing process. For example, some simple rotating platforms are used in small annealing equipment. By rotating the material during the heating process, the temperature difference caused by the fixed heating source is alleviated to a certain extent. However, these existing rotary annealing attempts still have many shortcomings. On the one hand, the control of its rotation speed and angle is not precise enough to form an effective synergy with the temperature control, and it is difficult to ensure that all parts of the material can be heated evenly throughout the annealing cycle; on the other hand, the matching temperature control system is not perfect, lacking continuous, real-time, and high-precision temperature monitoring and adjustment capabilities, and cannot meet the needs of modern industry for high-quality annealing processes.

[0055] Each of the first rotating rings is provided with at least one group of displacement grooves extending along the axial direction, and the displacement grooves between adjacent first rotating rings are connected;

[0056] A radial partitioned rotating structure, which has a plurality of movable radial components distributed along the circumferential direction, each of the movable radial components is arranged on the side of the second rotating ring close to the inner axis of the furnace shell, and each of the first rotating rings is provided with at least one detachable movable radial component, and the movable radial component moves to another first rotating ring through the displacement groove;

[0057] Each of the layered heat-insulating structures is correspondingly coated on one side of the first rotating ring close to the inner axis of the furnace shell;

[0058] The temperature generator includes a plurality of heating elements, each of which is evenly distributed on the side walls of the internal space enclosed by the layered thermal insulation structure, and is used to generate heat to anneal the workpiece arranged on the clamping portion. Each of the heating elements is electrically connected to a temperature controller outside the furnace body shell, and the temperature controller is used to control the power of each heating element. The temperature generator also includes a temperature sensor, which is arranged in the internal space enclosed by the layered thermal insulation structure, and is used to monitor the temperature of the internal space in real time and feed back the temperature signal to the temperature controller.

[0059] As a preferred embodiment, the layered heat-insulating structure is fixedly connected to the inner wall of the furnace shell, so that the first rotating ring moves relative to the layered heat-insulating structure;

[0060] or

[0061] The layered heat-insulating structure is fixedly connected to the first rotating ring, so that the layered heat-insulating structure moves synchronously with the first rotating ring.

[0062] As a preferred embodiment, two opposite groove walls of the displacement groove are respectively provided with track teeth and metal contacts, two opposite sides of the movable radial component are respectively provided with a driving motor and an energy supply contact, and the movable radial component has a first end and a second end on the side where the driving motor is provided, and the driving motor is provided at the first end and the second end, and the end of the driving motor is rotatably connected with the movable radial component; the other end of the driving motor is provided with a gear meshing with the track teeth, and the energy supply contact supplies energy to the driving motor after contacting with the metal contact.

A gear is provided at the end of the driving motor, and a track tooth is provided on the displacement groove wall, and the gear is meshing with the track tooth. When the driving motor obtains energy and starts to rotate, the gear will roll along the track tooth. Since the track tooth is fixed on the displacement groove wall, under the meshing action of the gear and the track tooth, this rotational motion will be converted into a linear motion of the movable radial component along the direction of the displacement groove, thereby realizing the movement of the movable radial component. Furthermore, the drive motor is rotationally connected to the movable radial component, which ensures that the motor itself can rotate flexibly during the rotation of the motor, and will not hinder the movement of the movable radial component, further ensuring the smoothness of the movement process.
