[0035] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.
[0036] Before introducing in detail the design method for the water gap of the crystallizer copper plate provided by an embodiment of the present invention, a brief introduction to the implementation environment involved will be given first.
[0037] The crystallizer is used to cool the molten steel so that the molten steel gradually solidifies into a shell with the required specifications and shapes. The crystallizer includes a copper plate and an immersion nozzle. The copper plate is arranged on the inner wall of the crystallizer. A water gap is formed on the copper plate, and the water gap is sealed by a back plate so that the cooling water flows in the water gap to play a role in cooling the molten steel. The immersion nozzle is a refractory casting sleeve inserted below the molten steel surface in the crystallizer and is used to introduce the molten steel into the crystallizer. The immersion nozzle has side holes, and the molten steel flows into the crystallizer through the side holes.
[0038] Among them, the copper plate covers the inner wall of the crystallizer, and multiple water gaps will be formed on the copper plate. The multiple water gaps are distributed on the copper plate so that the four sides of the crystallizer can be cooled. The size of each water gap in the prior art is the same, so that the cooling intensity in different areas of the copper plate is the same.
[0039] Figure 1 is a flowchart of a design method for the water gap of the crystallizer copper plate provided by an embodiment of the present invention. As Figure 1 shown, the method includes:
[0040] Step S110: Obtain the old size of the water gap of the old copper plate of the crystallizer, as well as the crack state and the temperature during operation of the old copper plate.
[0041] Among them, the crack state includes having cracks and no cracks.
[0042] In the design method of the embodiment of the present application, based on the old dimensions of the old copper plate water gap, the new dimensions of the new copper plate water gap are designed to minimize the changes and save the design cost. The old dimensions can be obtained from the design scheme of the old copper plate water gap. During the operation of the old copper plate, the temperature of the copper plate is detected in real time through a thermocouple. Check the surface condition of the old copper plate to obtain the crack state to understand whether there are cracks on the old copper plate.
[0043] Step S120: If the crack state is cracked or the change amount of the temperature within a set time period is greater than a preset temperature threshold, adjust the old dimensions, and use the adjusted old dimensions as the new dimensions of the new copper plate water gap of the mold.
[0044] In the embodiment of the present application, if the crack state is cracked, it indicates that the old copper plate is unevenly heated during operation, resulting in cracks on the old copper plate. If the change amount of the temperature within a set time period is greater than a preset temperature threshold, it indicates that the temperature of the old copper plate fluctuates greatly for a long time during operation and is unevenly heated. If the old copper plate has an uneven heating situation, it means that the old dimensions of the old copper plate water gap are not reasonably designed, resulting in the cooling intensity not meeting the production requirements. Therefore, the old dimensions can be adjusted to obtain new dimensions, and the new copper plate water gap is designed according to the new dimensions, so as to improve the heating uniformity of the new copper plate, thereby improving the solidification uniformity of the billet shell and the casting stability, further reducing the cracks on the new copper plate, reducing the grinding amount of the new copper plate when it is taken off the production line, and increasing the number of times the new copper plate can be used.
[0045] Among them, the duration of the set time period can be set according to the situation. For example, divide the entire operation cycle of the old copper plate into multiple set time periods, and then check the temperature fluctuation situation within each set time period.
[0046] Optionally, the old dimensions include at least one of the old width and the old depth.
[0047] In the embodiment of the present application, by adjusting the old width or the old depth of the water gap, the cooling intensity of the water gap can be changed, thereby improving the heating uniformity of the copper plate.
[0048] Optionally, the old dimensions further include the old shape, and adjusting the old dimensions includes: adjusting the old width or the old thickness while keeping the old shape unchanged.
[0049] In the embodiment of the present application, the old width or the old depth of the water gap can be adjusted, but the old shape needs to be kept unchanged, that is, the shape of the new copper plate water gap should be the same as that of the old copper plate water gap, so as to ensure that the cooling effect brought by the adjusted old dimensions can be closer to the expected value.
[0050] In the embodiments of the present application, the old copper plate can also be divided into multiple regions, and a temperature detection point is provided in each region. A thermocouple is arranged at each temperature detection point, and the temperature of the temperature detection point is detected by the thermocouple. The temperature of this region is reflected by the temperature of the temperature detection point in each region. Each region may correspond to one or more water gaps of the old copper plate.
[0051] Optionally, step S120 includes:
[0052] If the change amount of the temperature within the set time period is greater than the preset temperature threshold, determine the region where the temperature detection point with the change amount greater than the temperature threshold is located, denoted as the first target region; increase the old width of the water gap of the old copper plate in the first target region or decrease the old depth of the water gap of the old copper plate in the first target region.
[0053] In the embodiments of the present application, if the change amount of the temperature within the set time period is greater than the preset temperature threshold, it indicates that the temperature fluctuates for a long time. Then, determine which temperature detection points have long-term temperature fluctuations, and then determine the regions where these temperature detection points are located, denoted as the first target regions, that is, the temperatures of the first target regions fluctuate for a long time. Next, adjust the old dimensions of the water gaps of the old copper plates corresponding to the first target regions.
[0054] Specifically, increase the old width of the water gap of the old copper plate in the first target region, so that the water flow velocity in the water gap in the first target region decreases, reducing the heat transfer effect, thereby reducing the cooling intensity of the first target region. Or, decrease the old depth of the water gap of the old copper plate in the first target region, so that the distance between the cooling water in the water gap and the molten steel becomes farther, thereby reducing the cooling intensity of the first target region. Because the long-term temperature fluctuation in the first target region may be caused by too strong cooling intensity in the first target region, reducing the cooling intensity of the first target region can reduce the temperature fluctuation in the first target region, making the sizes of the water gaps of the new copper plates in different regions different, adapting to the different requirements for cooling intensity in different regions, and improving the heat absorption uniformity and shell solidification uniformity of the entire copper plate.
[0055] It should be noted that during the production process, affected by the molten steel flow field in the mold, the cooling intensity required in different regions of the mold may be different, while the sizes of all the water gaps on the old copper plate are the same, resulting in the same cooling intensity in all regions of the mold. Therefore, the water gaps with the same size can no longer meet the requirements for stable production in the current environment. Therefore, adjust the old dimensions of the regions with too strong cooling intensity to reduce the cooling intensity of the over-strong regions, so that the size of the water gap in each region matches the cooling intensity requirement of each region.
[0056] In the embodiments of the present application, the old copper plate includes a wide-side old copper plate and a narrow-side old copper plate, and the wide-side old copper plate and the narrow-side old copper plate are spliced together to cover the inside of the mold with copper plates.
[0057] Optionally, step S120 includes:
[0058] If the change in temperature within a set time period is greater than a preset temperature threshold, then the area where the corner formed by the combination of the wide-side old copper plate and the narrow-side old copper plate is located or the area closest to the submerged entry nozzle is determined as the first target area; increase the old width of the water gap of the old copper plate within the first target area or decrease the old depth of the water gap of the old copper plate within the first target area.
[0059] In the embodiment of the present application, if the change in temperature within a set time period is greater than a preset temperature threshold, it indicates that the temperature fluctuates for a long time and the heat transfer of the copper plate is too fast, resulting in uneven solidification of the billet shell. The areas most likely to have this situation are the area where the corner formed by the combination of the wide-side old copper plate and the narrow-side old copper plate is located or the area closest to the submerged entry nozzle. Because the corner where the wide-side old copper plate and the narrow-side old copper plate are combined is not easy to conduct heat, and the demand for cooling intensity is poor. And the gap formed between the copper plate in the area closest to the submerged entry nozzle and the submerged entry nozzle is small, the molten steel contained is less, and the required cooling intensity is less. Therefore, these two areas are used as the first target areas. Reducing the cooling intensity of these two areas can make the heat uniformity of the mold better.
[0060] Optionally, step S120 includes:
[0061] If the crack state is cracked, then determine the area where the crack is located, denoted as the second target area; reduce the old width of the water gap of the old copper plate within the second target area or increase the old depth of the water gap of the old copper plate within the second target area.
[0062] In the embodiment of the present application, if there is a crack on the old copper plate, it indicates that the old copper plate is locally overheated, resulting in cracks due to long-term fatigue. Then determine the area where the crack is located, thereby determining the overheated area, and denote it as the second target area; reduce the old width of the water gap of the old copper plate within the second target area, increase the water flow rate of the water gap, improve the cooling intensity of the second target area, and reduce the temperature of the copper plate in the second target area; or increase the old depth of the water gap of the old copper plate within the second target area, making the distance between the cooling water and the molten steel closer, which is more conducive to cooling the molten steel, that is, improving the cooling intensity, thereby reducing the temperature of the copper plate in the second target area and further reducing the cracks.
[0063] Optionally, step S120 includes:
[0064] If the crack state is cracked, then determine the area corresponding to the position where the molten steel flows back at the submerged entry nozzle as the second target area; reduce the old width of the water gap of the old copper plate within the second target area or increase the old depth of the water gap of the old copper plate within the second target area.
[0065] In the embodiment of the present application, if there are cracks in the old copper plate, it indicates that the old copper plate is locally overheated. The most likely area where overheating occurs is the area corresponding to the position of the upward steel flow in the flow field of the submerged nozzle. Because the steel liquid flow velocity in the upward flow area is relatively fast and a stronger cooling intensity is required, the cooling intensity of the water gap with the old size cannot meet the cooling demand. Therefore, this area is determined as the second target area, and then the old width of the water gap of the old copper plate in the second target area is reduced or the old depth of the water gap of the old copper plate in the second target area is increased to improve the cooling intensity of the second target area, so that the temperature of the copper plate in the second target area is reduced, overheating does not occur, and the occurrence of cracks is reduced.
[0066] In the embodiment of the present application, by adjusting the old size of the water gap in the first target area or the second target area, the size of the water gap in different areas is matched with the cooling intensity requirements of different areas, thereby improving the heat uniformity of the steel plate and the solidification uniformity of the billet shell, and reducing the occurrence of cracks.
[0067] Of course, the old sizes of other areas except the first target area and the second target area may not be adjusted, or may be slightly adjusted according to the actual situation to make the cooling effect better.
[0068] It should be noted that the water gap size of the new copper plate can be designed individually according to the conditions of different old copper plates.
[0069] In the embodiment of the present application, after designing the new size of the water gap of the new copper plate, the new copper plate can be directly produced and processed. However, since there may be a difference between the expected effect of the designed new size and the actual application effect, when the new copper plate is processed and the actual application does not meet the expectation, the new copper plate may face the risk of being scrapped, resulting in a large economic loss. Therefore, a cover plate with a certain size can be processed, and the old size of the water gap of the old steel plate can be adjusted through the cover plate.
[0070] For example, the cover plate is directly covered above the water gap of the old steel plate, and the old size of the water gap of the old steel plate is adjusted by the thickness, width or shape of the cover plate, which not only achieves the purpose of optimizing the water gap structure, but also reduces the risk of scrapping when directly processing the water gap of the new copper plate, and has high feasibility.
