Problems solved by technology

[0002] During the production and processing of aluminum alloy strip, it needs to be sent to the finishing equipment for strip surface cleaning treatment. It uses hot water to clean the aluminum alloy strip. The production process cannot evaluate the water content of the strip surface in time, that is, it cannot judge the water content of the strip surface after the end of production. Whether the strip may have the risk of water washing corrosion, the problem of water content on the strip surface is not dealt with in time, it is easy to cause batch corrosion coil accidents, and with the mass production of high-grade anodized materials such as 5052 and 5252 in 3C materials, water washing corrosion will affect the quality of the product

Embodiment Construction

[0024] In this embodiment, the detection handle 3 is an aluminum handle with a yield strength of 130-240 mpa, a thickness of 1.5-2.0 mm, and a length of 250 mm.

[0025] In this embodiment, the cushion block 4 is a plastic foam board.

[0026] In this embodiment, the fixed rope 2 is a rubber band.

[0027] A method for online inspection of strip surface moisture, comprising the following steps:

[0028] (1) Make the testing tool: First, take the testing paper 1 and fold it to make 2~6 layers. The external dimensions are required to be 20~50mm wide and 20~120mm long. A cushion block 4, then wrap the folded detection paper 1 around the test end of the detection handle, and then use a fixed rope 4 to bind the detection paper 1 and the detection handle 3;

[0029] (2) Detection: hold the holding end of the detection handle 3, press the test end of the detection handle 3 against the surface of the running strip on the production line, and after the contact length between th...

Abstract

The invention relates to a device and method for on-line inspection of water content of the surface of a band. The device comprises a detection handle and a detection paper. The front end of the detection handle is a detection end, the rear end of the detection handle is a holding end, a cushioning block is arranged at the detection end, the detection end is coated with the detection paper, the detection paper coats the cushioning block and the detection end, and the tail end of the detection paper is fixedly bound to the detection handle. The detection handle is hold in hand and the detection end of the detection handle presses against the surface of a band running in a production line, after the length of contact between the detection end and the band is 10-15m, the detection end is shifted out, a tester observes the detection paper of the detection end contacting with the band to determine whether the detection paper is damaged, if the detection paper is damaged, it is proved that the surface of the band contains water so that the band needs to be subjected to surface treatment, and if the detection paper is undamaged, it is proved that the band surface does not contain water. The device is simple to manufacture and the detection method is simple and effective. The detection paper damage degree is increased and the number of the damaged layers is increased along with increasing of band water content. The device and method can produce stable and effective detection results and effectively prevent washing corrosion.
