Description

Technical Field

[0001] The utility model belongs to the technical field of cooling, and more specifically, relates to a continuous casting billet cooling device. Background Art

[0002] The continuous casting billet is formed by injecting molten steel into a continuous casting machine. After the billet is produced by the continuous casting machine, cooling water is sprayed on the billet to cool it down. In the existing cooling devices, when cooling the billet, generally, the upper surface of the billet is sprayed, which may lead to poor cooling effects on the other two sides and the lower surface of the billet, and further result in poor cooling effect of the billet.

[0073] As Figure 3 shown, preferably, a water storage cavity 5 is arranged inside the fixed table 1, a plurality of through holes 6 are arranged on the top of the fixed table 1, and a water outlet hole is arranged at the bottom of the fixed table 1.

[0074] Specifically, the water storage cavity 5 can store the cooling water that falls after cooling the continuous casting billet and can be discharged through the water outlet hole. The cooling water can be reused or discarded according to actual needs.

[0075] Preferably, the continuous casting billet cooling device further includes a water inlet pipe 8 and a drain pipe 28, and the water inlet pipe 8 and the drain pipe 28 are respectively connected to the water inlet hole and the water outlet hole.

During this process, cooling water is introduced through the water inlet pipe 8 and discharged from the spray nozzles 7 on the elbow pipe 2, the horizontal pipe 3 and the vertical pipe 4 to spray-cool the billet. The sprayed cooling water falls onto the fixed table 1 and passes through the through holes 6 into the water storage cavity 5, and finally is discharged through the drain pipe 28. The cooling water can be reused or discarded according to actual needs.

[0084] When it is necessary to adjust the applicable horizontal range of the cooling device according to the size of the billet, first remove the bolts between the two horizontal pipes 3 at the center. When extension is required, move the moving frame 13 connected to the first rack 11 outwards. The first rack 11 drives the first gear 10 to rotate, and finally drives the second rack 12 to move in the opposite direction, driving the other moving frame 13 outwards. At this time, select an appropriate number of horizontal pipes 3 according to requirements and place them between the two separated horizontal pipes 3 in sequence, and connect and fix them with bolts. When the number of horizontal pipes 3 reaches the requirement, tighten all the bolts between the horizontal pipes 3. At this time, when pulling the moving frame 13, the other moving frame 13 has a tendency to move outwards, but is fixed by the interconnected horizontal pipes 3 to achieve the fixation of the device. When it is necessary to shorten the horizontal distance, just reduce the number of horizontal pipes 3 accordingly; when it is necessary to extend the longitudinal distance, remove the bolts between the two middle vertical pipes 4 and move the first receiving plate 24 upwards. At this time, drive the third rack 20 to move upwards, drive the second gear 19 to rotate, and drive the fourth rack 21 to move downwards, driving the second receiving plate 25 upwards, increase the number of vertical pipes 4 and fix them. When it is necessary to shorten the longitudinal distance, just reduce the corresponding number of vertical pipes 4; the universality of this cooling device is relatively high, the size of the cooling area can be adjusted, and it can be applied to billets of different sizes for temperature reduction.
