Description

Technical Field

[0001] This utility model belongs to the field of steel production technology, and in particular relates to a rapid heat treatment device for strip steel. Background Technology

[0002] In strip steel production lines, strip steel needs to undergo heat treatment. Annealing is a metal heat treatment process that involves slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize dimensions, and reduce the tendency for deformation and cracking.

[0003] After heat treatment, steel may have some oxide scale and decarburized layer impurities remaining on its surface. If these impurities are not cleaned in time, they may affect the performance of the steel during subsequent processing or use. To address these issues, the following solutions are proposed. Utility Model Content

[0004] The purpose of this invention is to provide a rapid heat treatment device for strip steel. By setting up a cooling mechanism and a collection mechanism, it solves the problem that some oxide scale and decarburized layer impurities may remain on the surface of the heat-treated steel. If these impurities are not cleaned in time, they may affect the performance of the steel during subsequent processing or use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a rapid heat treatment device for strip steel, including a main body, on which a cooling mechanism and a collection mechanism are provided;

[0007] Cooling vents are provided on the outer wall of the main body, a shell is fixedly connected to the outer wall of the main body, a fixing rod is fixedly connected to the top of the main body, and a fixing sleeve is fixedly connected to the end of the fixing rod away from the main body.

[0008] Furthermore, the cooling mechanism also includes a drive motor fixedly connected to the inner wall of the fixed sleeve, and a gear two is fixedly connected to the output shaft of the drive motor.

[0009] Furthermore, the cooling mechanism also includes a rotating rod rotatably connected to the top of the main body. The bottom end of the rotating rod extends into the main body and is rotatably connected to the main body. Gear 1 is fixedly connected to the outer wall of the rotating rod, and gear 1 meshes with gear 2.

[0010] Furthermore, the cooling mechanism also includes a movable groove at the top of the rotating rod, and several agitator plates are fixedly connected to the outer wall of the rotating rod. A sliding groove 1 is provided on the side wall of the agitator plate, and a sliding groove 2 is provided at the top of the sliding groove 1.

[0011] Furthermore, the cooling mechanism also includes a limiting rod fixedly connected to the inner wall of the second slide, a collecting plate slidably connected to the outer wall of the limiting rod, and a spring fixedly connected to the side of the collecting plate that is close to the slide.

[0012] Furthermore, the collecting mechanism also includes a support plate fixedly connected to the top of the main body. The top of the support plate has a slot 1, and an L-shaped rod is slidably connected in the slot 1. The end of the L-shaped rod away from the slot 1 extends into the movable groove and is slidably connected to the movable groove.

[0013] Furthermore, the collection mechanism also includes a slot 2 on the top of the support plate, a locking rod is slidably connected in the slot 2, the outer wall of the locking rod is fixedly connected to the L-shaped rod, a collection box is slidably connected to the inner wall of the movable groove, the top inner wall of the collection box is fixedly connected to the L-shaped rod, and several through slots are opened on the outer wall of the rotating rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. When heat treatment of steel is required, first start the drive motor, then put the steel to be heat treated into the coolant inside the main body, start the drive motor, the drive motor drives gear two to rotate, gear two drives gear one to rotate the rotating rod, the rotating rod drives several agitator plates to rotate, the rotation of several agitator plates can accelerate the flow of coolant, making the coolant generate strong convection, the convection of water can accelerate the speed at which heat is transferred from the surface of the strip steel to the water, so that the strip steel can dissipate heat more quickly, thereby accelerating the cooling speed;

[0016] 2. After heat treatment of steel, some impurities such as oxide scale and decarburized layer may remain on the surface of the steel. These impurities will float on the liquid surface. When several agitator plates rotate, centrifugal force is generated, which forces the collecting plate to slide outward on the outer wall of the limit rod. During the sliding process, the collecting plate will exert a pulling force on the spring. The rotation of the agitator plates can collect the impurities floating on the liquid surface into the chute. When the rotation stops, the centrifugal force on the collecting plate also disappears, and the spring drives the collecting plate to complete the reset. During the reset process, the collecting plate can... The impurities collected in the chute are pushed into the through trough, and then into the collection box. The workers then use an L-shaped rod to lift the collection box and process the collected impurities. When the collection plate is reset under the action of the spring, it pushes the impurities into the through trough and then into the collection box. The whole process ensures that the impurities can be effectively transferred out of the coolant, realizing the centralized collection of impurities, which is convenient for subsequent unified processing and reduces the possibility of impurities remaining in the processing equipment. This allows for faster and more comprehensive cleaning of impurities on the liquid surface, preventing impurities from spreading in the liquid or re-adhering to the steel surface.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5As shown, this utility model is a rapid heat treatment device for strip steel, including a main body 101. A cooling mechanism 1 and a collecting mechanism 2 are provided on the main body 101. A cooling port 102 is opened on the outer wall of the main body 101. A housing 103 is fixedly connected to the outer wall of the main body 101. A fixing rod 104 is fixedly connected to the top of the main body 101. A fixing sleeve 105 is fixedly connected to the end of the fixing rod 104 away from the main body 101. The cooling mechanism 1 also includes a drive motor 106 fixedly connected to the inner wall of the fixing sleeve 105. A gear is fixedly connected to the output shaft of the drive motor 106. The cooling mechanism 1 also includes a rotating rod 107 rotatably connected to the top of the main body 101. The bottom end of the rotating rod 107 extends into the main body 101 and is rotatably connected to the main body 101. A gear 108 is fixedly connected to the outer wall of the rotating rod 107. The gear 108 meshes with the gear 2 17. The cooling mechanism 1 also includes a movable groove 109 opened at the top of the rotating rod 107. Several stirring plates 110 are fixedly connected to the outer wall of the rotating rod 107. A sliding groove 111 is opened on the side wall of the stirring plate 110. A sliding groove 2 112 is opened at the top of the sliding groove 111.

[0028] When heat treatment of steel is required, the drive motor 106 is started first, and then the steel to be heat treated is placed in the coolant in the main body 101. The drive motor 106 is started, and the drive motor 106 drives the gear 2 17 to rotate. After the gear 2 17 rotates, it drives the rotating rod 107 to rotate through the gear 1 108. After the rotating rod 107 rotates, it drives several agitator plates 110 to rotate. The rotation of the agitator plates 110 can accelerate the flow of coolant and make the coolant generate strong convection. The convection of water can accelerate the speed at which heat is transferred from the surface of the strip steel to the water, so that the strip steel can dissipate heat more quickly, thereby accelerating the cooling speed.

[0029] Cooling mechanism 1 also includes a limiting rod 113 fixedly connected to the inner wall of slide 112. A collecting plate 114 is slidably connected to the outer wall of the limiting rod 113. A spring 115 is fixedly connected to the side of the collecting plate 114 that is close to the slide 112. The collecting mechanism 2 also includes a support plate 201 fixedly connected to the top of the main body 101. A slot 202 is provided on the top of the support plate 201. An L-shaped rod 203 is slidably connected in the slot 202. The L-shaped rod 203 is away from the slot. One end of 202 extends into the movable groove 109 and is slidably connected to the movable groove 109. The collection mechanism 2 also includes a second slot 204 opened on the top of the support plate 201. A locking rod 205 is slidably connected in the second slot 204. The outer wall of the locking rod 205 is fixedly connected to the L-shaped rod 203. A collection box 206 is slidably connected to the inner wall of the movable groove 109. The top inner wall of the collection box 206 is fixedly connected to the L-shaped rod 203. Several through slots 207 are opened on the outer wall of the rotating rod 107.

[0030] After heat treatment, steel may retain impurities such as oxide scale and decarburized layer on its surface. These impurities float on the liquid surface. When several agitator plates 110 rotate, centrifugal force is generated, forcing the collecting plate 114 to slide outward against the outer wall of the limiting rod 113. During this sliding process, the collecting plate 114 exerts a pulling force on the spring 115. The rotation of the agitator plates 110 collects the impurities floating on the liquid surface into the trough 111. When the rotation stops, the centrifugal force on the collecting plate 114 disappears, and the spring 115 drives the collecting plate 114 to reset. During the reset process, the collecting plate 114 can... The impurities collected in the chute 111 are pushed into the through chute 207, and then into the collection box 206 through the through chute 207. The workers then pull up the collection box 206 with the L-shaped rod 203 to process the collected impurities. When the collection plate 114 is reset under the action of the spring 115, it pushes the impurities into the through chute 207 and then into the collection box 206. The whole process ensures that the impurities can be effectively transferred out of the coolant, realizing the centralized collection of impurities, which is convenient for subsequent unified processing and reduces the possibility of impurities remaining in the processing equipment. This allows for faster and more comprehensive cleaning of impurities on the liquid surface, preventing impurities from spreading in the liquid or re-adhering to the steel surface.

[0031] A specific application of this embodiment is as follows: When steel needs to be heat-treated, the drive motor 106 is started first, and then the steel to be heat-treated is placed in the coolant in the main body 101. The drive motor 106 is started, and the drive motor 106 drives the gear 2 17 to rotate. After the gear 2 17 rotates, it drives the rotating rod 107 to rotate through the gear 1 108. After the rotating rod 107 rotates, it drives several agitator plates 110 to rotate. After the several agitator plates 110 rotate, they can accelerate the flow of coolant and make the coolant generate strong convection. The convection of water can accelerate the speed at which heat is transferred from the surface of the strip steel to the water, so that the strip steel can dissipate heat more quickly, thereby accelerating the cooling speed.

[0032] After heat treatment, steel may retain impurities such as oxide scale and decarburized layer on its surface. These impurities float on the liquid surface. When several agitator plates 110 rotate, centrifugal force is generated, forcing the collecting plate 114 to slide outward against the outer wall of the limiting rod 113. During this sliding process, the collecting plate 114 exerts a pulling force on the spring 115. The rotation of the agitator plates 110 collects the impurities floating on the liquid surface into the trough 111. When the rotation stops, the centrifugal force on the collecting plate 114 disappears, and the spring 115 drives the collecting plate 114 to reset. During the reset process, the collecting plate 114 can... The impurities collected in the chute 111 are pushed into the through chute 207, and then into the collection box 206 through the through chute 207. The workers then pull up the collection box 206 with the L-shaped rod 203 to process the collected impurities. When the collection plate 114 is reset under the action of the spring 115, it pushes the impurities into the through chute 207 and then into the collection box 206. The whole process ensures that the impurities can be effectively transferred out of the coolant, realizing the centralized collection of impurities, which is convenient for subsequent unified processing and reduces the possibility of impurities remaining in the processing equipment. This allows for faster and more comprehensive cleaning of impurities on the liquid surface, preventing impurities from spreading in the liquid or re-adhering to the steel surface.
