Description

Technical Field

[0001] The utility model relates to the technical field of rolling mills, in particular to a rolling mill spraying device with an anti-splashing mechanism. Background Art

[0002] A rolling mill is a device that realizes the metal rolling process. In the cold rolling process of steel strips, it is necessary to continuously spray coolant on the surface of the rollers to cool them down. At the same time, lubricants are also required to be sprayed. Generally, the coolant and lubricant are mixed into an emulsion and then sprayed onto the surface of the rollers and the strip. In the prior art, spraying is achieved by using nozzles, but after a large amount of emulsion is sprayed onto the equipment (roller or steel strip surface), it is very easy to cause liquid splashing everywhere. These splashed liquids are not only easy to cause harm to operators, but also easy to cause short circuits in electrical equipment, causing equipment failures, which not only affects production efficiency and quality, but also poses a great safety hazard.

[0003] Traditionally, the spraying devices used in rolling mills are mostly fixed on the rolling mills, which is inconvenient to move. In addition, the splash-proof effect of the device is poor, which is not conducive to use and needs to be developed urgently. Utility Model Content
