  • Patent number: 7160847
    Abstract: A method for chemical etching is disclosed for taking away oxidized film and removing cut as well as punched edge burs of harden-treated carbon steel (SK3, SK4 and SK5). Thereby, the fillet edge of the cut section is achieved. An oxidized film with a thickness of several micrometers is formed when a cut and punched steel is quenched and tempered at high temperature. Due to high strength and hardness of the steel, the oxidized film and edge burs are difficult to be removed by mechanical grinding. Therefore, a suitable electrolyte composes of only a little chemical reagent and oxidizer in deionized water is used to remove the oxidized film and punched bur simultaneously using chemical etching method.

    Abstract: The invention relates to a method for one-bath chemical cleaning and preservation of interior surfaces of hollow steel bodies, without any organic solvents, comprising controlled change of the liquid bath in that in a circuit of hoses running from a mobile tank equipped with a pump unit and steam generator there is circulated a liquid stream to a defined cavity of steel. The composition of the liquid is changed methodically by the addition of fresh chemical additives until the end of the process. Fresh water at 80° C. has added thereto an alkaline degreasing liquid A containing chlorine-free tensides, which is circulated, whereupon cleaning liquid B, consisting of citric acid with added cationic tensides, is added to a pH of 4.5 and is circulated. There is then added a complexing derusting liquid C, with active modified aminocarboxykate made biologically degradable, with adjustment of the pH to 4.5–5.
