Abstract
Description
Technical Field
[0001] This utility model relates to a zirconium core collection device for a tundish slider, belonging to the technical field of refractory equipment in the metallurgical industry. Background Technology
[0002] The tundish slide block is a type of shaped refractory material that primarily functions to control the flow of steel in continuous casting. Slide blocks with different inner diameters can be used to match the varying casting speeds of the continuous casting machine. Since molten steel flows directly through the inside of the tundish slide block, its high-temperature resistance and erosion resistance must be fully considered during its design and manufacturing to ensure stability and reliability during use. To achieve these performance requirements, a sizing zirconium core is typically embedded inside the tundish slide block, with the zirconium core containing approximately 95% ZrO2.
[0003] In continuous casting production, the consumption of tundish slide blocks is enormous. A 6-strand small billet continuous casting machine uses over 50 slide blocks per casting cycle (30 hours / cycle). For a steel company with an annual steel production of 3 million tons, this amounts to approximately 28,000 slide blocks consumed annually. Each discarded tundish slide block contains 0.2 kg of zirconium core, equivalent to 5.6 tons of discarded zirconium cores annually. With a market price exceeding 50,000 RMB / ton for 95% industrial zirconium oxide, the recycling benefit exceeds 300,000 RMB / year. However, due to the high-temperature sintering process, the bond between the tundish slide block and the zirconium core is very tight, making it difficult to sort and collect after forced crushing, resulting in a low current zirconium core recovery rate for tundish slide blocks.

The upper support is a rectangular frame structure that cooperates with the intermediate package slider. The hydraulic cylinder is fixed to the upper support through the hydraulic cylinder support. The intermediate package slider is disposed inside the upper support and is located directly below the hydraulic cylinder push rod. The lower end of the hydraulic cylinder push rod is connected to the top block, and the top block cooperates with the zirconium core inside the intermediate package slider. The upper support is fixed to the lower support, and a collection basket that cooperates with the zirconium core is provided below the lower support.

[0016] The present invention will be further described below with reference to the accompanying drawings and examples.
[0017] See attached document Figure 1 , 2 A zirconium core collection device for a waste intermediate package slider 5 includes an upper support 1, a lower support 2, a cylinder support 3, a top block 7, a cylinder push rod 8, a cylinder 9, and a collection basket 12. The upper support 1 is a rectangular frame structure that cooperates with the intermediate package slider 5. The cylinder 9 is fixed to the upper support 1 through the cylinder support 3. The intermediate package slider 5 is set inside the upper support 1 and is located directly below the cylinder push rod 8. The lower end of the cylinder push rod 8 is connected to the top block 7, and the top block 7 cooperates with the zirconium core 6 inside the intermediate package slider 5. The upper support 1 is fixed to the lower support 2, and the collection basket 12 that cooperates with the zirconium core 6 is provided below the lower support 2.
[0018] In this embodiment, as shown in the appendix Figure 1 , 2 As shown, a zirconium core collection device for an intermediate tundish slider includes an upper support 1, a lower support 2, a hydraulic cylinder support 3, an intermediate tundish slider 5, a zirconium core 6, a top block 7, a hydraulic cylinder push rod 8, a hydraulic cylinder 9, a hydraulic cylinder clamping plate 10, a hydraulic cylinder handle 11, a collection basket 12, and a collection basket handle 13, wherein:
[0019] The upper support 1 is a rectangular frame structure that cooperates with the intermediate slide block 5. The hydraulic cylinder 9 is installed on the hydraulic cylinder support 3. The hydraulic cylinder support 3 is welded to the upper part of the upper support 1. The vertical spacing of the hydraulic cylinder support 3 is matched with the thickness of the hydraulic cylinder clamping plate 10. The horizontal spacing of the hydraulic cylinder support 3 is between the outer diameter of the hydraulic cylinder 9 and the horizontal spacing of the hydraulic cylinder clamping plate 10. The hydraulic cylinder 9 is installed on the hydraulic cylinder support 3 through the hydraulic cylinder clamping plate 10.
[0020] The end of the hydraulic cylinder push rod 8 is connected to the top block 7, which is a cylinder. The diameter of the top block 7 is the same as the inner diameter of the intermediate tundish slider 5, and it covers the end face of the zirconium core 6 as much as possible.
[0021] After the intermediate tundish slider 5 is placed inside the upper bracket 1, it fits against three sides of the upper bracket 1. A round hole is opened on the bottom of the upper bracket 1. The round hole, the center of the intermediate tundish slider 5, the center of the top block 7, and the center of the hydraulic cylinder push rod 8 are coaxial.
