Description

Technical Field

[0001] This utility model relates to the field of copper plate cladding technology for crystallizers, and in particular to a device for preventing deformation of copper plate cladding in crystallizers. Background Technology

[0002] The crystallizer is a water-cooled ingot mold and a crucial component of a continuous casting machine. Its function is to continuously cool molten steel at high temperatures into a billet of specified dimensions and geometry, which is then smoothly pulled out at a controlled speed. Its technical performance directly impacts the internal structure and surface quality of the ingot, as well as the casting speed and production efficiency of the continuous casting machine. During operation, the copper plates in the crystallizer are subjected to prolonged scouring by molten iron, resulting in significant friction and wear. To ensure the wear resistance and corrosion resistance of the copper plates, surface coating or modification is often necessary. Laser cladding is a surface modification technology that involves adding a cladding material to the surface of the copper plates. A high-energy-density laser melts and solidifies the powder, forming a metallurgically bonded cladding layer with the copper plate surface. This significantly improves the surface hardness, wear resistance, and corrosion resistance of the copper plates.

[0003] In laser cladding, the high-energy laser beam generates localized high temperatures when it acts on the surface of the copper plate in the crystallizer. This uneven heating causes the copper plate to warp or twist, affecting the quality of the cladding layer and the dimensional accuracy of the copper plate. Therefore, it is necessary to fix and cool the copper plate in the crystallizer during laser cladding. Existing technologies often use clamps for fixation and air cooling. However, these technologies have some problems: on the one hand, traditional clamps only mechanically fix the edges of the copper plate and cannot effectively suppress the deformation of the copper plate in the crystallizer caused by internal thermal stress; on the other hand, traditional air cooling methods have low heat dissipation efficiency and cannot quickly remove the high heat input from the laser, still making it difficult to avoid deformation of the copper plate in the crystallizer during cladding. Utility Model Content

[0004] To address the technical problem that traditional clamps and air-cooling methods still cannot prevent deformation of the copper plate in the crystallizer during melting, this utility model provides the following technical solution.

[0005] This utility model discloses a device for preventing deformation of copper plates in a crystallizer during melting and cladding. It includes a support plate on which the copper plate is placed and two oppositely arranged fixed side plates on the left and right sides of the support plate. Each of the two fixed side plates has a movably arranged water-cooled clamping plate for clamping the copper plate on its opposite side. The support plate has a centrally located water inlet tank and a centrally located water outlet tank at its front and rear ends, respectively. The centrally located water inlet tank and the centrally located water outlet tank are respectively provided with an inlet and an outlet connected to an external circulating water tank. The water-cooled clamping plates have several clamping plate screw holes at both ends, and the water-cooled clamping plates have a water-cooling channel that extends through to the centrally located water inlet tank and the centrally located water outlet tank. The centrally located water outlet tank includes several second through holes communicating with the copper plate cooling channel of the copper plate.

[0006] As a further technical solution, the transfer water tank is provided with a number of connecting screw holes that match the screw holes of the clamp plate and a first through hole that matches the water cooling channel.

[0007] As a further technical solution, the upper part of the support plate is provided with a placement groove, and the copper plate is placed in the placement groove.

[0008] As a further technical solution, a sealing cover is provided on the upper part of the transfer water tank to facilitate the disassembly of the transfer water tank and the water-cooling clamp.

[0009] As a further technical solution, the fixed side plate is equipped with a thermocouple for monitoring the temperature of the copper plate cladding area.

[0010] As a further technical solution, the intermediate water inlet tank and the intermediate water outlet tank have the same structure and are arranged opposite to each other.

[0011] The beneficial effects of this utility model are as follows: A copper plate is placed on the upper part of the support plate, and the copper plate is externally fixed by two water-cooling clamps, a transfer water inlet tank, and a transfer water outlet tank. By rigidly constraining the copper plate from all sides, deformation of the crystallizer copper plate caused by internal thermal stress can be effectively suppressed. At the same time, the copper plate's internal water-cooling channel is connected to the transfer water inlet tank and the transfer water outlet tank, which can cool the inside of the copper plate with water. Combined with the two water-cooling clamps, the transfer water inlet tank, and the transfer water outlet tank, the copper plate is forcibly cooled and uniformly constrained and fixed from all sides. The copper plate has high heat dissipation efficiency, which can effectively suppress the thermal deformation of the copper plate during the cladding process and ensure the cladding quality of the crystallizer copper plate.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0017] like Figure 1 As shown, this utility model discloses a device for preventing deformation of the copper plate in a crystallizer during cladding. It includes a support plate 1 on which a copper plate 4 is placed. The upper part of the support plate 1 has a placement groove 401, within which the copper plate 4 is placed. The placement groove 401 matches the lower shape of the copper plate 4, allowing the copper plate 4 to be placed in an accurate position. A copper plate cooling channel 401 penetrates the copper plate 4. The copper plate 4 and the copper plate cooling channel 401 are existing crystallizer copper plate structures, therefore their specific structures will not be described in detail.

[0018] like Figure 2As shown, in a preferred embodiment, the support plate 1 has two oppositely arranged fixed side plates 2 on its left and right sides respectively. Each of the two fixed side plates 2 has a movably arranged water-cooled clamping plate 3 for clamping the copper plate 4 on its opposite side. The two water-cooled clamping plates 3 can clamp and cool the copper plate 4 from both sides. The support plate 1 has a central water inlet tank 5 and a central water outlet tank 6 oppositely arranged at its front and rear ends respectively. The two ends of the two water-cooled clamping plates 3 are connected to the central water inlet tank 5 and the central water outlet tank 6 respectively. The circulating cold water in the central water inlet tank 5 and the central water outlet tank 6 can pass through the water-cooled clamping plates 3 to cool the copper plate 4. Simultaneously, the central water inlet tank 5 and the central water outlet tank 6 temporarily store circulating cold water, which can clamp and cool the copper plate 4 from both the front and rear ends. Therefore, forced cooling and uniform constraint fixation can be performed on the bottom perimeter of copper plate 4, improving the heat dissipation efficiency of copper plate 4. During the cladding process, thermal deformation of copper plate 4 can be effectively suppressed, ensuring the cladding quality of the crystallizer copper plate.

[0019] In a preferred embodiment, the intermediate water inlet tank 5 and the intermediate water outlet tank 6 have identical structures and are arranged opposite each other. The intermediate water outlet tank 6 includes several second through holes 604 communicating with the copper plate cooling channel 401. The copper plate cooling channel 401 and the second through holes 604 are connected by existing quick-release connectors. The figure shows multiple second through holes 604. Once a second through hole 604 is connected to the copper plate cooling channel 401, the remaining second through holes 604 can be plugged. Cold water can enter the copper plate cooling channel 401 through the through holes of the intermediate water inlet tank 5, cool the copper plate 4, and then exit through the second through holes 604. The copper plate cooling channel 401 itself can be used to cool the interior of the copper plate 4, improving the heat dissipation efficiency of the copper plate 4.

[0020] In a preferred embodiment, the intermediate water inlet tank 5 and the intermediate water outlet tank 6 are respectively provided with an inlet 7 and an outlet 8. The inlet 7 and the outlet 8 are connected to an external circulating water tank. The circulating water tank is provided with cold water at about 20-25 degrees Celsius. The water can enter the intermediate water inlet tank 5 through the inlet 7 and flow through the water-cooled clamping plate 3 and the copper plate 4 respectively. Then it is discharged from the intermediate water outlet tank 6 and the outlet 8, thus completing the cooling of the inside and the surrounding area of ​​the copper plate 4.

[0021] In a preferred embodiment, the water-cooled clamping plate 3 has several clamping plate screw holes 301 at both ends, and the intermediate water outlet tank 6 has several connecting screw holes 601 that match the clamping plate screw holes 301. The clamping plate screw holes 301 and the connecting screw holes 601 are connected using bolts to complete the connection between the water-cooled clamping plate 3 and the intermediate water outlet tank 6. The water-cooled clamping plate 3 has a water-cooling channel 302 that connects to the intermediate water inlet tank 5 and the intermediate water outlet tank 6. The intermediate water outlet tank 6 has a first through hole 602 that matches the water-cooling channel 302, thus allowing the water-cooling channel 302 to connect the intermediate water inlet tank 5 and the intermediate water outlet tank 6. The upper part of the intermediate water outlet tank 6 has a sealing cover plate 603. Opening the sealing cover plate 603 facilitates the disassembly of the intermediate water outlet tank 6 and the water-cooled clamping plate 3. Alternatively, the lower part of the sealing cover plate 603 can press against the copper plate 4, thereby pressing and fixing the copper plate 4. It should be noted that the fixed side plate 2 is equipped with a thermocouple for monitoring the temperature of the copper plate 4 cladding area.

[0022] In use, the copper plate 4 is first placed in the placement groove 101, and then two water-cooling clamps 3 are respectively inserted between the two sides of the copper plate 4 and the fixed side plate 2. Then, the copper plate cooling channel 401 and the second through hole 604 are connected, and the water-cooling channel 301 is connected to the first through hole 601. Then, the two ends of the two water-cooling clamps 3 are connected and fixed to the intermediate water inlet tank 5 and the intermediate water outlet tank 6. Then, the water inlet 7 and the water outlet 8 are connected to the external circulating water tank, the water pump is started, and the initial water flow rate is set to 5L-10L / min and the water temperature is 20℃-25℃. The laser cladding equipment is turned on, and the temperature monitoring module is started simultaneously. When the thermocouple detects that the temperature of the cladding area exceeds 150℃, the water flow rate is automatically increased to 15L / min. After the cladding is completed, the external circulating water tank is turned off.

[0023] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention.
