Description

Technical Field

[0001] This utility model belongs to the field of nickel plate annealing technology, and specifically relates to a precise control continuous annealing device for N02200 pure nickel plates. Background Technology

[0002] N02200 pure nickel plates possess excellent corrosion resistance, high thermal and electrical conductivity, and good machinability. However, cold working processes such as rolling and stamping can cause the plate surface to harden, requiring recrystallization annealing to restore plasticity and improve subsequent processing performance. After heat treatment of nickel plates, traditional annealing equipment cannot evenly disperse inert gas, resulting in large temperature variations. Uneven heating of the nickel plate leads to localized overheating or underheating, affecting the annealing effect.

[0003] A search revealed that prior art patent publication number CN 118256700 A describes a continuous annealing device for heating tube steel strips with heat recovery. During annealing, it uses heat-absorbing and cooling components to control the temperature. However, the lack of protective gas for the steel strip results in excessively high surface hardness and the formation of multiple oxide layers, affecting the annealing quality. Another search revealed a continuous annealing device for preventing oxidation of bright steel strips, published under patent publication number CN 222139211 U. This device uses nitrogen and hydrogen as protective gases introduced into the annealing furnace via an inlet mechanism. However, it cannot guarantee uniform distribution of the protective gas within the furnace, leading to gas waste and significant temperature differences, thus affecting the final annealing result. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a precise control continuous annealing device for N02200 pure nickel plates. The device uses an adjustment mechanism to make the sprayed inert gas more uniform in the box. The conveying mechanism can stir the inert gas in the box while conveying the nickel plates. Stirring the inert gas can generate convection, making the inert gas more uniform inside the box.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A precise control continuous annealing device for N02200 pure nickel plates includes a nickel plate, a box, positioning rollers, a heat insulation cover, a conveying mechanism, an adjusting mechanism, an inert gas conveying pipe, and heating pipes. The nickel plate is positioned into the box by the positioning rollers. The inert gas conveying pipe is located inside the box and supplies inert gas to the inside of the box. The inert gas protects the nickel plate during annealing. An adjusting mechanism is provided on the inert gas conveying pipe. The conveying mechanism is also provided inside the box. Multiple sets of heating pipes are provided on the upper part of the box to heat the inside of the box. A heat insulation cover is provided above the heating pipes to ensure the temperature inside the box.

[0007] The inert gas delivery pipe includes a main pipe, branch pipes, terminal pipes, and a high-pressure nozzle; the main pipe is provided with branch pipes, the branch pipes are provided with terminal pipes, the branch pipes and the terminal pipes are rotatably connected, and the terminal pipes are provided with high-pressure nozzles.

[0008] The adjusting mechanism includes a positioning plate I, a fixed frame, gears, racks, a connecting rod, and an electric actuator. Two sets of positioning plates I are fixed to a branch pipe of the inert gas delivery pipe. The gears are located on the terminal pipe of the inert gas delivery pipe. A fixed frame is provided between the two sets of positioning plates I, and the fixed frame is fixedly connected to the positioning plates I. Three sets of racks are located within the fixed frame, and the three sets of racks are staggered. The racks are slidably connected to the fixed frame. A connecting rod is provided between the racks, connecting the three sets of racks. The racks mesh with the gears. The electric actuator is fixed to the fixed frame. On the fixed frame, the top end of the electric actuator connects to the connecting rod; the electric actuator pushes the connecting rod, which drives three sets of racks to move simultaneously. The racks mesh with gears, and the gears drive the terminal pipes to rotate. The three sets of racks are staggered. When the connecting rod is pushed, the middle rack drives the gears to rotate in the opposite direction to the gears on both sides, so that the rotation direction of the middle set of terminal pipes is opposite to the rotation direction of the terminal pipes on both sides. The rotation of the terminal pipes can be adjusted according to the needs to make the sprayed inert gas more uniform in the box and prevent uneven concentration caused by dead airflow.

[0009] The conveying mechanism includes a motor I, a motor mounting frame, conveying rollers, and a transmission belt I; the motor I is installed inside the motor mounting frame, which is fixed to the outside of the housing; the output end of the motor I is connected to the conveying rollers; there are three sets of conveying rollers, and the three sets of conveying rollers are connected to each other by the transmission belt I.

[0010] One end of a set of conveying rollers in the conveying mechanism is also provided with a transmission belt II, which connects the conveying rollers to the transmission shaft I. The transmission shaft I is located between two sets of positioning plates II, and the transmission shaft I is rotatably connected to the positioning plates II. The positioning plates II are fixed on the upper part of the heat insulation cover. Two sets of helical gears I are provided on the transmission shaft I, and the helical gears I mesh with the helical gears II. The helical gears II are located on the transmission shaft II. The transmission shaft II passes through the heat insulation cover and extends into the interior of the box. The lower part of the transmission shaft II is provided with spiral blades.

[0011] Motor I controls the rotation of the conveyor rollers, which transport nickel plates forward. The three sets of conveyor rollers are connected by transmission belt I. As the conveyor rollers rotate, they drive transmission shaft I to rotate via transmission belt II. Transmission shaft I drives helical gear I to rotate, and helical gear I meshes with helical gear II. Helical gear II drives transmission shaft II to rotate, and transmission shaft II drives the spiral blades to stir the inside of the chamber. While transporting the nickel plates, it also stirs the inert gas inside the chamber, generating gas convection. This ensures that the inert gas is more uniform inside the chamber during the annealing process, preventing oxidation of the nickel plates due to insufficient inert gas in certain areas.

[0012] The main pipeline is horizontally arranged along the outer side of the long side of the enclosure. Eight branch pipelines are installed on the main pipeline, with four branch pipelines located at the top and four at the bottom. The upper and lower branch pipelines form a mirror-symmetric structure in the vertical plane. A suitable distance is maintained between adjacent branch pipelines to ensure airflow stability. Both ends of all branch pipelines are fixed inside the enclosure. Each branch pipeline has three terminal pipelines equidistantly spaced along the axial direction, connected by universal joints. Initially, the terminal pipelines are perpendicular to the branch pipelines, and a safe distance is maintained between adjacent terminal pipelines to ensure no interference during rotation. Four sets of high-pressure nozzles are equidistantly installed on the surface of each terminal pipeline, with the nozzle direction always parallel to the nickel plate. Inert gas, after pressure regulation, is diverted from the main pipeline to the eight branch pipelines, and then evenly distributed to the terminal pipelines. Finally, it forms a three-dimensional, intersecting air curtain network through the high-pressure nozzles, providing comprehensive, all-around protection for the annealed nickel plate inside the enclosure and effectively preventing high-temperature oxidation.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] The regulating mechanism adjusts the direction of the terminal pipeline to prevent uneven concentration of inert gas due to density differences and to prevent uneven concentration caused by dead airflow. The conveying mechanism can stir the inert gas in the box while conveying the nickel plate, generating gas convection. This ensures that the inert gas is more uniform inside the box during the annealing process and avoids oxidation of the nickel plate due to insufficient inert gas in some areas.

A connecting rod 205 is provided between the racks 204, connecting the three sets of racks 204. The racks 204 mesh with the gears. 203. The electric actuator 206 is fixed on the fixed frame 202, and the top end of the electric actuator 206 is connected to the connecting rod 205.

The racks 204 mesh with the gears 203, and the gears 203 drive the terminal pipe 103 to rotate. The three sets of racks 204 are staggered.

While the conveying rollers 303 are rotating, they drive the transmission shaft I 306 to rotate via transmission belt II 305. The transmission shaft I 306 drives the helical gear I 308 to rotate. The helical gear I 308 meshes with the helical gear II 309. The helical gear II 309 drives the transmission shaft II 310 to rotate. The transmission shaft II 310 drives the spiral blades 311 to stir the inside of the box 12. While conveying the nickel plate 11, the inert gas inside the box 12 is stirred, generating gas convection.

Each terminal pipe 103 has four sets of high-pressure nozzles 104 equidistantly arranged on its surface. The nozzle direction of all high-pressure nozzles 104 is always parallel to the nickel plate 11.
