Description

Technical Field

[0001] This utility model belongs to the field of cooling technology, and specifically relates to a hinged device for rapid cooling of high-temperature slabs. Background Technology

[0002] During the rolling process, various factors on-site can cause billet jamming accidents. The billet temperature during rolling is generally above 800℃. After jamming, the high-temperature billet needs to be cooled rapidly in order to cut it and push it into the scrap storage area to resume normal production. Since there is no effective equipment for rapid cooling of billets, manual cooling can only be done by fire water pipes. However, the high-temperature billet will quickly vaporize or splash iron scale when it comes into contact with cooling water, which can easily injure on-site personnel and poses a significant safety hazard. Furthermore, the high temperature prevents close-range cooling, resulting in poor cooling effect. The high-temperature billet can also damage the transport rollers. Therefore, it is necessary to design a device that can ensure personnel safety and provide rapid cooling. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a device for rapid cooling of high-temperature slabs with an articulated connection, so as to achieve a large-area cooling effect and meet the requirements of water spray cooling in multiple directions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hinged rapid cooling device for high-temperature slabs includes a base, a sleeve connected to the base, a water guide pipe inside the sleeve, a water inlet pipe connected to the bottom of the water guide pipe, a water spray pipe connected to the top of the water guide pipe via a rotary joint, an extension water spray pipe connected to the outer end of the water spray pipe via a rotary joint, nozzles on the water spray pipe and the extension water spray pipe, and a water spray pipe support device on the outside of the sleeve.

[0006] The water spray pipe support device includes a cylinder body, which is sleeved on the outside of the sleeve. A connecting plate is connected to the bottom of the cylinder body, and the connecting plate is connected to the tray by tray bolts. The tray is fixedly connected to the sleeve. A base plate is connected to the cylinder body by a bracket, and a support plate is provided on the base plate. The base plate is connected to the support plate by support bolts.

[0007] The tray is provided with an arc-shaped elongated hole in the circumferential direction for connecting tray bolts.

[0008] A water pump is connected to the inlet pipe.

[0009] Compared with existing technologies, the beneficial effects of this utility model are:

[0010] 1) The use of a rotary joint allows the water spray pipe to rotate horizontally. During rolling, the water spray pipe can be rotated to one side of the track for easy storage, and can be quickly rotated to the required position when in use. This achieves a large-area cooling effect and can meet the needs of water spray cooling in multiple directions.

[0011] 2) It is equipped with an extended water spray pipe that can rotate to adapt to the cooling of wide slabs.

[0012] 3) Install a rotatable water spray pipe support device to solve the support strength problem of single-sided support, and ensure the support plate supports the water spray pipe by adjusting the support bolts.

[0013] This invention can quickly cool steel billets, reducing the cooling time for handling hot billets, improving work efficiency, reducing spare parts wear, and preventing burns to workers. It is easy to maintain, saves significant energy and costs, and meets on-site safety production requirements. Attached Figure Description
