It is rare to install an emulsion spray beam under or on the side of the pinch roller, because the emulsion dripped from the top will flow from top to bottom along the surface of the pinch roller due to gravity to wet the entire surface of the pinch roller. surface, but the wetting of the entire surface of the pinch roll is detrimental if the emulsion spray beam is placed on the lower part or on the side; therefore, it seems inevitable that this causes the problem of emulsion dripping
[0007] In view of the above situation, it is usually necessary to stop the spraying of the nozzle in advance and ensure that the residual emulsion on the nozzle and the spray beam has been completely dripped when the aluminum strip is rolled up. However, this process generally takes three to five minutes, which greatly Affected the work efficiency of winding

Embodiment 1
[0067] This embodiment provides a lubricating device for a pinch roller, including: a reflection shield 1, a spray assembly 2, a purge assembly 3 and an oil intake assembly 4; wherein, the reflection shield 1 is arranged above the pinch roller And parallel to the horizontal plane, the opening of the reflective shield 1 faces the pinch roller; the reflective shield 1 includes a flat plate 11 and two side plates 12, the two side plates 12 are oppositely arranged on both sides of the flat plate 11, and the side plates 12 and Edges are formed at the splices of plate 11 (see figure 1 ), the flat plate 11 is located 10cm above the nozzle 22; the length×width×height of the reflective shield 1 is 165cm×10cm×12cm, which can be adapted to a pinch roller with a diameter of 320mm×length of 1650mm. The specific size setting principle is as follows: The length can cover the length of the pinch roller, and the width should not exceed the width of the pinch roller. The height of the side plat...
Embodiment 2
[0070] This embodiment provides a lubricating device for pinch rollers. Compared with Embodiment 1, the difference lies in that the connection between the flat plate 11 and the side plate 12 is changed from an edge to an arc shape Connection, the radius of the arc is 3cm, and the rest of the structure is exactly the same as that of Example 1.
[0071] The above-mentioned lubricating device for pinch rollers is used to lubricate the pinch rollers. The lubricating method is basically the same as the method in Example 1; the lubricating time is 240s. Under the same cleaning state, the inner wall purging time is 8s, and the total oil consumption during the lubrication process is 500kg.
[0072] Compared with Example 1, Example 2 sets the connection between the flat plate 11 and the side plate 12 in an arc shape, that is, the cross section of the reflective shield is a U-shaped structure, and there is no edge between adjacent inner walls, so as to avoid the edge caused by the edge....
Embodiment 3
[0074] This embodiment provides a lubricating device for pinch rollers. Compared with Embodiment 1, the difference is that the flat plate 11 of the reflective shield 1 is located above the nozzle 22 of the spray assembly 2, and the distance between the two is 50 cm. The structure is exactly the same as that of Example 1.
[0075] The above-mentioned lubricating device for pinch rolls is used for the pinch roll lubrication method, and the lubricating method and effect are basically the same as those of the first embodiment.

Abstract
The invention relates to the technical field of hot rolling mills, and discloses a lubricating device and method for a pinch roll and a hot rolling mill, and the lubricating device comprises a reflecting shield, a spraying assembly, a purging assembly and an oil inlet assembly. The reflecting shield is arranged above the pinch roll and is parallel to the horizontal plane, and an opening of the reflecting shield faces the pinch roll; the spraying assembly is located between the reflecting protective cover and the pinch roll and comprises a spraying beam extending in the length direction of the reflecting protective cover, at least one nozzle is arranged at the top end of the spraying beam, and the spraying direction of the nozzle is perpendicular to the horizontal plane and faces upwards; emulsion is sprayed to the inner wall of the reflecting protective cover through the nozzle and reflected to the surface of the pinch roll for lubrication, and after lubrication, the blowing assembly is started to blow and clean the outer wall of the spraying assembly and the inner wall of the reflecting protective cover. When the aluminum strip is wound, emulsified liquid does not drop on the aluminum strip, and the winding working efficiency can be high.
Description
technical field [0001] The invention relates to the technical field of hot rolling mills, in particular to a lubricating device for pinch rolls, a lubricating method and a hot rolling mill. Background technique [0002] At present, in the process of hot rolling the aluminum strip, the aluminum strip is conveyed by the pinch rollers of the hot rolling mill; since the aluminum strip is still in a high temperature (300-450°C) state during hot rolling, in such a The aluminum strip is in a softened state at high temperature, and the aluminum strip is in direct contact with the surface of the pinch roll during transportation. When the softened aluminum strip contacts the pinch roll at room temperature, it is easy to cause the pinch roll The aluminum sticking phenomenon occurs on the surface, so that when the pinch roller conveys the aluminum strip next time, the aluminum bonded on the pinch roller will stick to the surface of the aluminum strip, thereby affecting the surface quali...
