Problems solved by technology

However, the high dispersion and messy atomization of the emulsion drops caused by the operation of the known equipment prevents this structure from being fully effective, even with the full use of the highest flow rate of compressed air

Embodiment Construction

[0047] The apparatus of the present invention for removing liquid or solid particles from metal strips comprises:

[0048] - Conveyor means for providing an air jet or air knife onto said strip as it is being conveyed, to remove emulsifiable concentrate or other liquid and / or solid particles deposited on said strip;

[0049] - air extraction equipment;

[0050] - a housing, for example in the form of a tube bell, containing said conveying means and communicating with said suction means for sucking air containing removed atomized emulsion and / or lifted solid particles.

[0051] figure 1 with 2 A first embodiment of the device is shown, generally numbered 1 .

[0052] Said conveying means comprise two conveying or conveying collectors 2, 2' provided with conveying pipes 4, 4' respectively located on one side of said apparatus.

[0053] In its part closest to the conveying direction of the strip 6, the conveying collector 2, 2' is provided with two separate parts 14, ...

Abstract

A device for removing a liquid or solid particles from at least one flat surface of metal products, such as strips, sheets, blooms or billets, exiting from rolling mill stands which allows a perfect, uniform removal of the emulsion and the total drying of the product thus eliminating the problems of quality deriving from the permanence of the emulsion on the finished product. The device, object of the present invention, may advantageously be applied in any process in which continuously drying and removing a liquid previously deposited on a surface in translating motion is required.

Description

Technical field: [0001] The present invention relates to equipment for the removal of liquid or solid particles from flat metal surfaces, in particular emulsifiable oil and / or pure oil and / or dust and / or dirt, for use in rolling processes, for example for cold rolling metal products The reversible rolling unit, dry and clean the flat surface of metal products. Background technique: [0002] Emulsifiable concentrates (oil emulsions) or pure oils are commonly used in rolling mills to lubricate the working area of ​​the rolls and ensure that they are sufficiently cooled. The introduction temperature of the emulsion is 50-60°C; while the temperature in the area of ​​the work roll contact surface (roll nip) exceeds 100°C (even during the cooling process of rolling), which leads to atomization of the emulsifiable oil. [0003] The speed of the strip being rolled can be up to, for example, 1500 m / min, or even higher, based on the thickness of the strip, and the high speed of rotat...
