Abstract
A water cooling roller with a self-circulation helical structure comprises an inner roller, an outer roller and water inlet and outlet devices disposed inside and outside an inner cavity of the inner roller, wherein radial boards are installed at two ends of each of the inner roller and the outer roller. The water cooling roller is characterized in that the inner roller and the outer roller form a cooling water cavity provided with an internal helical water passage. The helical water passage is added into the water cooling cavity of the water cooling roller, and on one hand, forced cooling water rotates along with the roller and realizes peripheral self-circulation along the water passage and around the roller wall in the cavity, a helical angle of the helical water passage further can lift and stir the cooling water when the roller rotates, accordingly the roller and a steel strip can be uniformly cooled, the cooling efficiency can be greatly increased, on the other hand, the additional helical water passage increases strength of the roller, accordingly the thickness of a steel plate of the outer wall of the roller can be reduced, and double purposes of increasing cooling effect and reducing dead weight can be achieved.
Description
(1) technical field: the utility model relates to a kind of continuous slab band unit water cooled rolls, specifically is a kind of water cooled rolls with self-loopa helical structure.
(2) background technology: water cooled rolls is the visual plant of continuous slab band unit, plays protection roller self structure shape and salband steel.At present, as cooling water cavity, the roller wall is thicker by the cavity that constitutes between interior roller and the outer roller for old-fashioned water cooled rolls, and cooling water can only accumulate in the bottom and can not rotate with roller in the chamber, so inhomogeneous cooling is even, and cooling effect is poor.
(3) summary of the invention: the purpose of this utility model just provides a kind of outer roller wall thickness that reduces, and improves cooling effect, alleviates the water cooled rolls with self-loopa helical structure of own wt.
The technical solution of the utility model comprises interior roller, outer roller, disc is equipped with at inside and outside roller two ends, also comprises the Inlet and outlet water device that reaches in the roller chamber in being arranged on outside the chamber, it is characterized in that: be provided with spirality channel in the cooling water cavity that described inside and outside roller constitutes.
The utility model is by adding spiral water channel in the cooling water cavity of water cooled rolls, forced cooling water is rotated with roller on the one hand, realization circumference self-loopa in the chamber around the roller wall along water channel, the helical angle of spiral water channel can have the effect that promotes with stirring to cooling water again in roller turn, thereby cooled roller and band steel significantly improve cooling effectiveness equably; After having added spirality channel on the other hand roller intensity is improved, therefore can reduce the thickness of outer roller wall steel plate, reach simultaneously and improve cooling effect and the double action that alleviates own wt.
Add man-hour, weld fixedly spirality channel earlier on interior roller outer wall, again according to outer roller inner diameter dimensional tolerance turning, inside and outside then roller assembling forms the cooling water cavity with spirality channel.The size of the helical angle of spirality channel wherein, the direction of spiral are then determined according to actual needs.The utility model is better through trial effect.
(4) description of drawings
Fig. 1 is the structural representation of the utility model master apparent direction;
Fig. 2 is the local structure for amplifying schematic diagram of spirality channel among Fig. 1.
Among the figure, roller in the 1-, the outer roller of 2-, 3-disc, 4-hollow shaft, 5-water inlet, 6-delivery port, 7-swivel joint, 8-dividing plate, 9-steel pipe, 10-intake antrum, 11-water chamber, 12-water supply hose, 13-delivery hose, 14-cooling water cavity, 15-spirality channel.
(5) specific embodiment:
Referring to Fig. 1, Fig. 2, the utility model comprises interior roller 1, outer roller 2, disc 3 is equipped with at the roller two ends, also comprise the Inlet and outlet water device that reaches in the roller chamber in being arranged on outside the chamber, the structure and the existing structure of this Inlet and outlet water device are similar, promptly be fixed with a hollow shaft 4 by the two ends disc at interior roller middle part, hollow shaft one end with bring delivery port 5 into, 6 swivel joint 7 connects, steel pipe 9 one ends that have 8, bands of dividing plate conical head of band bellmouth in the axle insert in the bellmouth of described dividing plate, and the other end communicates with the water inlet 5 of swivel joint 7, so just make hollow shaft be separated into intake antrum 10 and water chamber 11, thereby make the effective separating cycle of Inlet and outlet water.On intake antrum and water chamber, be connected to Inlet and outlet water flexible pipe 12,13 respectively; Roller wall or the water inlet of a side joint of waterway sidewall in generally can being chosen in according to the roller actual size, opposite side picks out water or indirect water inlet, and both sides pick out water.In the cooling water cavity 14 that described inside and outside roller constitutes, be provided with spirality channel 15.
Claims (1)
1. the water cooled rolls that has the self-loopa helical structure, comprise interior roller, outer roller, disc is equipped with at inside and outside roller two ends, also comprise the Inlet and outlet water device that reaches in the roller chamber in being arranged on outside the chamber, it is characterized in that: in the cooling water cavity that described inside and outside roller constitutes, be provided with spirality channel.
