Description

Technical Field

[0001] This invention relates to the field of heat treatment processing technology for wear-resistant liners, specifically to a heat treatment processing equipment for the production of wear-resistant liners. Background Technology

[0002] Wear-resistant liners are high-hardness protective plates laid on the inner walls of mechanical equipment to protect the equipment body and withstand continuous impact and wear from materials. In the production and processing of wear-resistant liners, the liners are generally heated in a furnace to fully dissolve the alloying elements and homogenize the internal structure. Then, the liners are rapidly cooled and quenched to form a microstructure such as martensite with extremely high hardness and wear resistance, thus giving the liners strong hardness and wear resistance.

[0003] In the prior art, when heat-treating wear-resistant liners in a box furnace, operators usually stack multiple liners on a rack, then transfer the rack and liners as a whole into the box furnace for heat treatment. After all the liners have been heated and heat-preserved, the liners in the rack are then immersed in a water tank for cooling and quenching.

[0004] However, the above-mentioned method of heat treatment using stacked liners has the following drawbacks: although stacking wear-resistant liners into the furnace can increase the amount of liners loaded into the furnace and the loading efficiency, the gaps between the tightly stacked liners are limited. This means that when the heat of the box furnace is transferred to the inner liner, it can almost only rely on the contact heat conduction of the outer liner. This heat transfer method is extremely inefficient. Even by extending the overall heat preservation time of the liner, it is difficult to make the inner liner reach the target temperature. Furthermore, it is easy to cause excessive coarsening of the surface grains of the outer liner that is directly exposed to high temperature for a long time and to cause severe oxidation and burn-off. At this time, the core of the inner liner may not be fully burned through because the heat cannot penetrate. As a result, the core of the inner liner cannot complete the proper microstructure transformation due to insufficient dissolution of carbides. Summary of the Invention

[0005] The purpose of this invention is to provide a heat treatment processing equipment for the production of wear-resistant liners, so as to solve the problem of large differences in the heat treatment effect of stacked liners in the prior art.

[0006] The technical problem to be solved by the present invention can be achieved by the following technical solution: a heat treatment processing equipment for the production of wear-resistant liners, including a partition table, wherein a stacking rack is provided on the partition table, and the stacking rack is used to stack wear-resistant liners at intervals.

[0007] The stacking rack includes a support plate and a locking block; multiple support plates are evenly arranged in the partition platform, and a locking block is provided on the upper side of the support plate. The support plate and the corresponding locking block are used to jointly support the wear-resistant liner.

[0008] Preferably, the stacking rack is provided with an unlocking component, which is used to sequentially release the load on the wear-resistant liner by each support plate and locking block.

[0009] The unlocking component includes an unlocking frame and a pulling frame; the unlocking frame is provided on the rear side of the locking block, and the locking block moves synchronously with the corresponding unlocking frame. The pulling frame is used to cooperate with the unlocking frame to drive the locking block to move in a specific direction.

[0010] Preferably, the partition and the unlocking component are both provided with a cooperating component, which is used to automatically release the corresponding locking block from locking the support plate.

[0011] The mating assembly includes an unlocking plate and a mating plate; an unlocking plate is provided between each adjacent locking block, and a mating plate is provided behind the unlocking plate. The mating plate moves synchronously with the upper adjacent unlocking frame, and the unlocking plate is used to cooperate with the lower support plate to drive the mating plate to move in a directional manner.

[0012] Preferably, the support plate includes an inclined plate and a horizontal plate. The inclined plate extends forward and upward, and its rear end is connected and fixed to the front end of the horizontal plate. A counterweight is fixedly installed on the lower side of the front end of the inclined plate. A rotating shaft is symmetrically fixed on the left and right sides of the middle part of the inclined plate, and the rotating shaft is rotatably connected to the corresponding vertical section on the partition platform.

[0013] Preferably, a locking block is provided on the upper side of the horizontal plate of the support plate, the front side of the locking block is inclined, and the lower surface of the locking block is in close contact with the upper surface of the corresponding horizontal plate.

[0014] Preferably, a limiting platform is provided behind the locking block, the limiting platform is fixedly connected to the vertical section of the dividing platform, and multiple guide rods are evenly arranged on the limiting platform at the front and back. The guide rods are slidably connected to the limiting platform and pass through the limiting platform at the front and back. The front end face of the guide rod is fixedly connected to the rear surface of the locking block.

[0015] Preferably, the unlocking frame is fixedly installed on the rear end face of each corresponding guide rod, the unlocking frame is located behind the limiting platform, and the unlocking frame has a slot that runs vertically through it.

[0016] Preferably, the pull frame is inverted L-shaped, with the vertical section of the pull frame located at the front end of its horizontal section. The lower end of the vertical section of the pull frame is a pointed tip that is inserted into a slot. The rear end of the horizontal section of the pull frame has symmetrical operating slots that extend through the horizontal section of the pull frame vertically.

[0017] Preferably, the unlocking plate includes a second inclined plate and a second horizontal plate. The second inclined plate extends backward and upward, and the front end of the second inclined plate is connected and fixed to the rear end of the second horizontal plate. The second horizontal plate is pressed and engaged with the first horizontal plate of the lower support plate. The left and right sides of the connection section between the second horizontal plate and the second inclined plate are symmetrically fixed with a second rotating shaft. The second rotating shaft is rotatably connected to the corresponding vertical section on the partition platform.

[0018] Preferably, the mating plate is inverted L-shaped, and the connection between the horizontal and vertical sections of the mating plate is tightly fitted with the upper end of the corresponding unlocking plate, the inclined plate two. A connecting frame is fixedly provided on the rear side of the vertical section of the mating plate, and the connecting frame is fixedly connected to the lower surface of the upper adjacent unlocking frame.

[0019] Compared with the prior art, the beneficial effects of this application are as follows: Before loading each wear-resistant liner into the furnace, by placing each liner on the upper surface of the inclined plate of the corresponding support plate, the liner moves downward along the inclined plate under its own weight and guided by the vertical section of the corresponding inclined plate and the partition plate until the lower end face of the liner is in contact with the front inclined surface of the corresponding locking block. Thus, the liner can be automatically calibrated and placed without the need for precise placement by the operator, thereby ensuring the overall liner placement efficiency. Most importantly, when transferring the partition plate and the liner placed on the stacking rack into the box furnace for heat treatment, the vertical separation of each liner by the support plate ensures that there is sufficient heat flow space between each liner, so that each liner can directly contact the high temperature inside the box furnace, thereby improving the stability and uniformity of the heat treatment of each liner. In addition, by stacking the liner vertically, the longitudinal space inside the box furnace can be fully utilized, thereby ensuring the overall number of liners loaded into the furnace. This invention utilizes a stacking rack to efficiently separate and stack the wear-resistant liners, thereby ensuring that each liner can maintain stable direct contact with the high temperature inside the box furnace, significantly improving the stability, uniformity, and heating efficiency of the heat treatment of each liner, enhancing the quality of the heat treatment process, and also ensuring the overall furnace loading efficiency of each liner.

Detailed Implementation

[0034] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0035] Example 1 While stacking wear-resistant liners in the furnace can increase the amount of liner plates and the efficiency of loading, the limited gaps between the tightly stacked liner plates mean that the heat transfer from the box furnace to the inner liner plates relies almost entirely on the contact heat conduction of the outer liner plates. This heat transfer method is extremely inefficient. Even by extending the overall heat preservation time of the liner plates, it is difficult for the inner liner plates to reach the target temperature. Furthermore, it can easily lead to excessive coarsening of the surface grains of the outer liner plates that are directly exposed to high temperatures for a long time, as well as severe oxidation and burn-off. Meanwhile, the core of the inner liner plates may not be fully burned through because heat cannot penetrate, resulting in insufficient dissolution of carbides and difficulty in completing the necessary microstructural transformation in the core of the inner liner plates.

[0036] like Figures 1 to 13 A heat treatment processing equipment for producing wear-resistant liners includes a partition table 1, which is U-shaped with the opening facing upwards. A stacking rack 2 is provided on the partition table 1 for stacking wear-resistant liners at intervals. The stacking rack 2 includes a support plate 21 and a locking block 22. Multiple support plates 21 are evenly arranged vertically inside the partition table 1, and a locking block 22 is provided on the upper side of the support plate 21. The support plate 21 and the corresponding locking block 22 are used to jointly support the wear-resistant liners.

[0037] like Figures 2 to 4The support plate 21 includes an inclined plate and a horizontal plate. The inclined plate extends forward and upward, and the upper surface of the inclined plate is used to place a wear-resistant liner. The rear end of the inclined plate is connected and fixed to the front end of the horizontal plate.

[0038] like Figures 2 to 4 A locking block 22 is provided on the upper side of the horizontal plate of the support plate 21. The front side of the locking block 22 is an inclined surface. The inclined surface of the front side of the locking block 22 is used to support the rear end face of the wear-resistant liner. The lower surface of the locking block 22 is in close contact with the upper surface of the corresponding horizontal plate.

[0039] The working principle of the support plate 21: Before loading each wear-resistant liner into the furnace, each liner is placed on the upper surface of the inclined plate 1 of the corresponding support plate 21. Under its own weight and guided by the vertical section of the corresponding inclined plate 1 and the partition plate 1, the liner moves downward along the inclined plate 1 until the lower end face of the liner is in contact with the front inclined surface of the corresponding locking block 22. Thus, the liner can be automatically calibrated and placed without the need for precise placement by the operator, ensuring the overall liner placement efficiency. Most importantly, when transferring the partition plate 1 and the liner placed on the stacking rack 2 into the box furnace (not shown in the figure) for heat treatment, the support plate 21 separates and places each liner vertically, ensuring sufficient heat flow space between each liner. This ensures that each liner can directly contact the high temperature inside the box furnace, thereby improving the stability and uniformity of the heat treatment of each liner. In addition, by stacking the liner vertically, the longitudinal space inside the box furnace can be fully utilized, thus ensuring the overall number of liners loaded into the furnace.

[0040] It should be emphasized that the core improvement of this embodiment is that: by stacking the wear-resistant liners in a highly efficient manner through the stacking rack 2, not only can each liner be in stable direct contact with the high temperature inside the box furnace, but the stability, uniformity and heating efficiency of the heat treatment of each liner are significantly improved, the quality of the heat treatment of the liner is enhanced, and the overall furnace loading efficiency of each liner is also guaranteed.

[0041] It should be noted that since the partition plate, stacking rack 2 and its related components all need to be placed in the high-temperature environment inside the box furnace along with the liner for operation, in order to ensure their long-term operational stability, the materials of the partition plate, stacking rack 2 and its related components must have strong heat resistance and creep resistance to ensure that the partition plate, stacking rack 2 and its related components can still stably perform their functions after long-term repeated heating and cooling thermal cycles.

[0042] Example 2 It is understandable that in Embodiment 1, after the heat treatment of each liner plate in the box furnace is completed, each liner plate on the stacking rack 2 needs to be put into the water tank for quenching. Since the space between each liner plate on the stacking rack 2 is limited and the overall number of stacked plates is large, when each liner plate is put into the water, the liner plates are more likely to collide with each other due to the obstruction of the water surface. At the same time, since the high temperature liner plates have low hardness and good plasticity, the collision is very likely to cause the liner plates to be dented, scratched or even deformed, thereby affecting the processing and forming quality of the liner plates.

[0043] like Figure 1 and Figure 2 The stacking rack 2 is provided with an unlocking component 3, which is used to release the load on the wear-resistant liner by each support plate 21 and locking block 22 in sequence; the unlocking component 3 includes an unlocking frame 31 and a pulling frame 33; the unlocking frame 31 is provided on the rear side of the locking block 22, and the locking block 22 moves synchronously with the corresponding unlocking frame 31; the pulling frame 33 is used to cooperate with the unlocking frame 31 to drive the locking block 22 to move backward.

[0044] like Figures 2 to 4 A counterweight 211 is fixedly installed on the lower side of the front end of the inclined plate 1 of the support plate 21. A rotating shaft is symmetrically fixed on the left and right sides of the middle of the inclined plate 1. The rotating shaft is rotatably connected to the corresponding vertical section on the partition platform 1. The center of gravity of the support plate 21 and the corresponding counterweight 211 is located in front of the rotating shaft. The center of gravity of the wear-resistant liner placed on the support plate 21 is also located in front of the rotating shaft. The frictional resistance between the locking block 22 and the horizontal plate 1 is greater than the horizontal component force applied by the wear-resistant liner to the locking block 22. The locking block 22 can move back and forth.

[0045] The working principle of unlocking component 3: When the wear-resistant liner plate on the stacking rack 2 that has undergone heat treatment needs to be quenched, the liner plate on the partition platform 1 and the stacking rack 2 is first transferred to the edge of the water tank (not shown in the figure) by external hoisting equipment (not shown in the figure), and the water tank is positioned in front of the partition platform 1 and the stacking rack 2. Then, the pulling frame 33 is used to pull the corresponding locking block 22 backward in sequence from bottom to top, in conjunction with each unlocking frame 31, until the locking block 22 is completely disengaged from the horizontal plate of the corresponding support plate 21. At this time, the support plate 21, which is no longer constrained by the locking block 22, will then be quenched by the corresponding counterweight block 211 and the wear-resistant liner plate. Under the influence of gravity, the liner rotates downward around the pivot until the inclined plate of the support plate 21 tilts forward and downward at a certain angle. The liner on the upper side of the inclined plate slides down into the pool under its own weight. Since there is a height difference between the upper and lower liners, and the locking blocks 22 unlock sequentially from bottom to top, it can be ensured that the upper adjacent liner only begins to slide into the pool after the lower liner is completely submerged in water. This ensures that the liners in the pool will not collide directly, avoiding damage, scratches and deformation caused by collisions, and ensuring the processing and forming quality of the liner.

[0046] It should be emphasized that the core improvement of this embodiment is that the support plate 21 is unlocked sequentially from bottom to top by the unlocking component 3, so that each liner can slide into the water tank sequentially from bottom to top for quenching, thereby avoiding damage, scratches or even deformation of each liner due to direct collision during water entry, and effectively ensuring the processing and forming quality of the liner.

[0047] It should be noted that although the lining plates may collide after being submerged in water, the impact intensity between the lining plates will be significantly reduced due to the buffering effect of the water in the pool. Furthermore, under the rapid cooling of the water, the hardness of the high-temperature lining plates will increase rapidly due to quenching, thereby further preventing the lining plates from being damaged, scratched, or deformed due to mutual collisions after being submerged in water.

[0048] It should be noted that, due to the high cost of the partition plate, stacking rack 2 and related components with strong heat resistance and creep resistance, the partition plate, stacking rack 2 and related components should not be quenched in the water tank along with the liner plate, so as to avoid significantly affecting the service life and structural strength of the partition plate, stacking rack 2 and related components.

[0049] It should be noted that, such as Figure 2 and Figure 5 A limiting platform 221 is provided behind the locking block 22. The limiting platform 221 is fixedly connected to the vertical section of the partition platform 1. Multiple guide rods 222 are evenly arranged on the limiting platform 221. The guide rods 222 are slidably connected to the limiting platform 221 and pass through the limiting platform 221 from front to back. The front end face of the guide rod 222 is fixedly connected to the rear surface of the locking block 22.

[0050] like Figure 1 , Figure 2 , Figure 5 and Figure 6 The unlocking frame 31 is fixedly installed on the rear end face of each corresponding guide rod 222. The unlocking frame 31 is located behind the limiting platform 221, and the unlocking frame 31 has a slot 32 that runs vertically through it. The pull frame 33 is inverted L-shaped. The vertical section of the pull frame 33 is located at the front end of its horizontal section. The lower end of the vertical section of the pull frame 33 is a pointed tip and is inserted into the slot 32. The rear end of the horizontal section of the pull frame 33 is symmetrically provided with operation slots 34, which penetrate the horizontal section of the pull frame 33 vertically.

[0051] When the locking block 22 is to be disengaged from the corresponding support plate 21, the operator first holds the control pull frame 33 through the control slot 34 and inserts the vertical section of the front end of the pull frame 33 into the corresponding slot 32 from top to bottom. Then, the operator drives the corresponding unlocking frame 31 to move backward quickly through the control pull frame 33. The unlocking frame 31 then drives the corresponding locking block 22 to move backward quickly along the limiting platform 221 through the guide rod 222 until the locking block 22 is completely disengaged from the horizontal plate of the corresponding support plate 21. At this time, the support plate 21 rotates in an directional manner under the gravity of the counterweight block 211 and the liner whose center of gravity has not yet changed.

[0052] Example 3 It is understandable that in Example 2, not only will a large amount of high-temperature steam be generated during the process of each high-temperature liner being placed in water, but the gradually increasing height of the high-temperature liner will also lead to a continuous increase in the splashing high-temperature liquid. At the same time, since there are a large number of liners and operators need to unlock and place them one by one, the operators will always be affected by high-temperature steam and splashing high-temperature liquid during the placement process. This will not only affect the efficiency of liner placement and quenching, but also significantly increase the safety hazards of liner placement operations.

[0053] like Figure 2 , Figure 7 and Figure 8 The partition platform 1 and the unlocking component 3 are both provided with a cooperating component 4. The cooperating component 4 is used to automatically release the corresponding locking block 22 from locking the support plate 21. The cooperating component 4 includes an unlocking plate 41 and a cooperating plate 42. An unlocking plate 41 is provided between each adjacent locking block 22. A cooperating plate 42 is provided behind the unlocking plate 41. The cooperating plate 42 moves synchronously with the upper adjacent unlocking frame 31. The unlocking plate 41 is used to cooperate with the lower support plate 21 to drive the cooperating plate 42 to move backward.

[0054] like Figure 2 and Figure 8 The unlocking plate 41 includes an inclined plate 2 and a horizontal plate 2. The inclined plate 2 extends backward and upward. The front end of the inclined plate 2 is connected and fixed to the rear end of the horizontal plate 2. The horizontal plate 2 is pressed and engaged with the horizontal plate 1 of the lower support plate 21. The left and right sides of the connection section between the horizontal plate 2 and the inclined plate 2 are symmetrically fixed with rotating shafts 2. The rotating shafts 2 are rotatably connected to the corresponding vertical section on the partition platform 1.

[0055] like Figure 2 and Figure 8The mating plate 42 is inverted L-shaped. The connection between the horizontal and vertical sections of the mating plate 42 is tightly fitted to the upper end of the corresponding unlocking plate 41 inclined plate 2. By limiting the fit between the horizontal and vertical sections of the mating plate 42 and the upper end of the unlocking plate 41 inclined plate 2, the unlocking plate 41 can be prevented from rotating around the second pivot under its own weight. A connecting frame 43 is fixedly provided on the rear side of the vertical section of the mating plate 42. The connecting frame 43 is fixedly connected to the lower surface of the adjacent upper unlocking frame 31.

[0056] Working principle of component 4: When placing the lining plates sequentially from bottom to top, the operator first pulls the bottommost unlocking frame 31 and locking block 22 backward using the pulling frame 33 until the bottommost locking block 22 is completely disengaged from the corresponding support plate 21 (e.g., Figure 9 As shown), the bottommost support plate 21 rotates around the pivot in a certain direction until the rear end of the bottommost support plate 21 (horizontal plate one) contacts the front end of the corresponding upper unlocking plate 41 (horizontal plate two). Figure 10 As shown, with the continuous directional rotation of the lowest support plate 21, the horizontal plate one of the lowest support plate 21 continuously presses upward against the horizontal plate two of the corresponding unlocking plate 41 on the upper side. The corresponding unlocking plate 41 then drives the rear end of the inclined plate two to rotate downward around the pivot two. The inclined plate two then simultaneously pushes the vertical section of the corresponding mating plate 42 backward. The mating plate 42 then drives the upper unlocking frame 31 and its corresponding locking block 22 to move backward through the connecting frame 43 until the inclined plate two of the unlocking plate 41 is in a horizontal state. At this time, the locking block 22, which moves synchronously with the mating plate 42, completely disengages from the corresponding support plate 21 (as shown). Figure 11 As shown); when the inclined plate of the lowest rotating support plate 21 tilts forward and downward at a certain angle, the lowest liner also slides down into the pool. At this time, the unlocking plate 41 corresponding to the lowest support plate 21 is completely disengaged from the vertical section of the corresponding mating plate 42 under the action of the horizontal plate of the support plate 21. At the same time, the support plate 21 on the upper side of the lowest support plate 21 also drives the corresponding unlocking plate 41 to rotate synchronously through directional rotation, so that the inclined plate of the corresponding unlocking plate 41 rotates to a horizontal state and pushes the corresponding mating plate 42 and locking block 22 backward in sync, so that the locking block 22 is also completely disengaged from the corresponding support plate 21 (as shown). Figure 12 As shown), until each unlocking plate 41, in conjunction with its corresponding mating plate 42, automatically releases the locking of each locking block 22 from bottom to top, thus automatically releasing the support of each liner from bottom to top, allowing each liner to automatically slide into the pool from bottom to top (as shown). Figure 13 (As shown).

[0057] It should be emphasized that the core improvement of this embodiment is that after the operator releases the lock of the lowest support plate 21, the support of each liner plate can be released sequentially from bottom to top through the cooperation of each unlocking plate 41 and the corresponding mating plate 42, so that each liner plate can be automatically put into the water from bottom to top. This avoids the continuous intervention of the operator in the placement of the liner plate and the impact of the high temperature steam and liquid generated during the placement process on the operator. This not only ensures the efficiency of liner plate placement and quenching, but also ensures the safety of the operator.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
