Abstract

The invention provides a wire rope pickling method. A phosphating film protection is provided to base metal through pickling, so as to prevent the metal from being corroded again; the phosphating film protection can be used for priming before painting; the adhesive force and the anti-corrosion ability of a paint film layer are improved; and the wire rope pickling method plays an anti-wearing lubrication role in metal cold processing technology. In addition, saponification is provided after phosphorization, and the protective property of the phosphating film of phosphating solution is greatly improved. Acid treatment of hydrochloric acid solution of which the concentration is gradually increased is carried out many times; greasy dirt and corrosion of the surface of the wire rope can be removed; the consumption of an acid liquor is reduced; and the smoothness of the treatment surface is provided. In addition, conservation of energy source is facilitated by normal-temperature soaking; the single soaking time of the acid liquor is shortened; and the hydrogen embrittlement phenomenon is prevented on the basis of saving the energy sources.

Description

technical field [0001] The invention relates to the field of steel wire rope manufacturing, in particular to a steel wire rope pickling method. Background technique [0002] The pickling process is a common method for producing industrial surfaces in the industry. It is used to remove all kinds of oil, rust, oxide skin, welding spots and other dirt. After the treatment, the surface of the rigid member is free of impurities, and it can be used as a pre-treatment process for other surface treatments. [0003] The traditional pickling process is extensive, and the waste of acid solution is relatively serious, and the degree of corrosion and descaling on the industrial surface is not the same, which affects the performance of the later processed products, and seriously causes repeated work or waste of materials. , and produce a large amount of exhaust gas. Contents of the invention [0004] The purpose of the present invention is to provide a steel wire rope pickling method, ...
