Corrosion resistance detection device for cold-rolled steel pipe

Abstract

The invention, which relates to the technical field of quality detection, further discloses a corrosion resistance detection device for a cold-rolled steel pipe. The corrosion resistance detection device comprises a support frame. A solution vessel is fixedly installed at the bottom of an inner cavity of the support frame; a solution detector is fixedly installed at one side of the inner cavity ofthe solution vessel; and the output end of the solution detector is electrically connected with the input terminal of a solution detection panel display device fixedly installed at the bottom of oneside of the support frame. The middles of the left side and the right side of the support frame are fixedly sleeved with the outer surface of a guide rail. According to the corrosion resistance detection device, with a ratchet wheel and a fixed rod, a rotating wheel can stably rotate in one direction by using a fixed spring and adjustment is rapid; the positions of the hook and the containing disccannot be changed in the long-time fixing process, so that a problem that the recorded data do not conform to the detection result because the soaking position of the cold-rolled steel pipe is changed in the detection process is solved and thus the detection result is improved.

Description

technical field [0001] The invention relates to the technical field of quality inspection, in particular to a corrosion resistance inspection device for cold-rolled steel pipes. Background technique [0002] Metal material refers to the general designation of metal elements or materials with metal properties mainly composed of metal elements, including pure metals, alloys, metal intermetallic compounds and special metal materials, etc. In modern times, a wide variety of metal materials have become human An important material basis for social development, but most metals and their alloys have poor corrosion resistance to acid and alkali solutions, so more and more attention has been paid to the detection of acid and alkali resistance of metal materials. The method of chemical immersion test is commonly used to detect the corrosion resistance of metals, but in the chemical immersion test, the results of the test are different for different immersion depths and positions. In th...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a corrosion resistance detection device for cold-rolled steel pipes, which has the advantages of convenient and quick adjustment of the detection depth position, high sealing performance of the detection device, good stability, and simple operation, and solves the problem of When the chemical immersion test method is used to detect the corrosion resistance of metals, the results of the test are different for different immersion depth positions in the chemical immersion test. In the existing detection device, the sealing is poor, and the detection environment is easy to affect the monitoring results. At the same time, it is more troublesome to adjust the detection depth of metal, and the stability is poor, which may easily cause a gap between the ideal position depth and the actual depth, resulting in the problem of low accuracy of detection results
