Hot-rolling seamless tube sizing roller cooling water ring

Abstract

The invention relates to a hot-rolling seamless tube sizing roller cooling water ring. The cooling water ring comprises cooling water ring bodies, and the cooling water ring bodies are movably arranged in gaps between adjacent roller racks; each cooling water ring body is composed of a water ring, a water inlet pipe, a first supporting rod and a second supporting rod, one end of the water ring isconnected with the horizontal water inlet pipe, and the water inlet pipe is connected with an external water pipe through a quick joint; multiple nozzles are uniformly arranged at the portion, corresponding to rollers at the two sides, in the circumferential direction of the water rings, and the number of the nozzles is the multiple of 3; the first supporting rods are arranged on the water rings,the second supporting rods are arranged on the water inlet pipes, and the first supporting rods and the second supporting rods achieve height-direction and radial-direction supporting and locating effects on the cooling water ring bodies. According to the hot-rolling seamless tube sizing roller cooling water ring, the movable cooling water ring bodies are adopted, configuration is conducted according to the using requirement, the number of configured and maintained racks is reduced, the situation that the cooling water ring is damaged when a roller rack is frequently overhauled is avoided, andthe water cooling effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hot-rolled pipe production, in particular to a cooling water ring for hot-rolled seamless pipe sizing rolls. Background technique [0002] In the production process of hot-rolled seamless pipes, the sizing rolls need to be water-cooled through the rack water pipe 3, and each roll rack 1 is equipped with a rack water pipe 3 (such as figure 1 Shown); Conventional rack water pipe 3 adopts The 18×2 red copper tube is arranged on the outside of the roll stand 1 according to the shape of the roll stand 1, and its connecting pieces are many and the shape is relatively complicated. Because the roll rack 1 needs frequent maintenance and frequent movement, the rack water pipe 3 often bumps and deforms or even leaks; in addition, due to the poor cleanliness of the water on site, the rack water pipe 3 is easily blocked, and it is difficult to dredge and repair. During the cooling process of roll 2, if the amount o...

[0002] In the production process of hot-rolled seamless pipes, the sizing rolls need to be water-cooled through the rack water pipe 3, and each roll rack 1 is equipped with a rack water pipe 3 (such as figure 1 Shown); Conventional rack water pipe 3 adopts The 18×2 copper tube is arranged on the outside of the roll stand 1 according to the shape of the roll stand 1. There are many connectors and the shape is relatively complicated.

Because the roll rack 1 needs frequent maintenance and frequent movement, the rack water pipe 3 often bumps, deforms or even leaks; in addition, due to the poor cleanliness of the on-site water, the rack water pipe 3 is easily blocked, and it is difficult to unblock and repair

During the cooling process of roll 2, if the amount of water decreases or lacks water, cracks, cracks or even cracks will appear on the surface of roll 2. At the same time, due to poor cooling effect, it is easy to cause bending defects of hot-rolled seamless pipes, which will destroy the normal production rhythm
