Background

In the hot rolling production process of steel, the temperature of a steel billet is generally over one thousand ℃, when a working roll of hot rolled steel is contacted with a high-temperature steel billet, the roll surface temperature of the working roll can be rapidly increased, and when the surface temperature of the roll is increased to 650 ℃, the hardness, the strength and the wear resistance of the roll of general materials can be rapidly reduced, so that the working roll must be cooled by cooling water in the hot rolling process, and the temperature of the working surface cannot be higher than 600 ℃.

In order to solve the problem, an arc-shaped pouring groove water pipe is often used for spraying cooling water to a rolling groove of the roller in the production process so as to cool the rolling groove and the whole roller. For example, utility model 201320565578.2 in the chinese patent document discloses a casting groove water pipe for cooling a rolling mill, which is a rolling groove for cooling a roll by spraying cooling water against a rolling groove using a semicircular casting groove water pipe concentric with the roll.

The water pipe for casting the groove can play a role in strengthening and cooling the groove of the roller, reduce the temperature rise of the roller, particularly the groove, relieve the thermal fatigue of the roller, prolong the service life of the roller and reduce the roller consumption. However, the problem of fixedly mounting the casting trough water pipes on the rolling mill cross beam or the frame is that when the rolling mill or the rolling trough on the rolling mill needs to be replaced, the upper and lower casting trough water pipes need to be detached first, then the rolling trough or the rolling mill can be replaced, and after the rolling trough or the rolling mill is replaced, the upper and lower casting trough water pipes need to be mounted again. When the arc-shaped water pipe of the pouring groove is fixed again, cooling water can not be sprayed into the rolling groove accurately, so that the water pipe is fixed again after being dismounted again, and the position of the water pipe of the pouring groove needs to be adjusted repeatedly. In addition, in the steel rolling process, the water pipe of the casting groove is inclined or moved due to mechanical vibration, so that cooling water cannot be accurately sprayed into the rolling groove, the cooling effect is affected, and the water pipe of the casting groove needs to be readjusted and fixed. Such operation requires the mill to be halted, which results in the mill being taken off-line, the downtime being extended, and the production efficiency being greatly reduced.
