Abstract
The invention discloses a surface cleaning process for a metal product. The process comprises the following cleaning steps: (1) cleaning by high-pressure water: jetting a metal product surface by using high-pressure water, and removing dirt attached to the surface; (2) scrubbing: scrubbing the metal product surface by using a brush; (3) cleaning by high-pressure water: jetting the metal surface by using high-pressure water again, and scrubbing the metal product scrubbed in the step (2); (4) pickling: putting the metal product cleaned in the step (3) into a pickling box to pickle; (5) drying: putting the metal product pickled in the step (4) into a drying baker to dry; and (6) inspecting: inspecting the metal product which is dried in the step (5). The process has the beneficial effects that the cleaning process is relatively simple, the cleaning effect is good, the process can be applied to automatic cleaning equipment, manpower consumed in the cleaning process is greatly reduced, the enterprise production cost is reduced, and the process is easy to popularize.
Description
Technical field
The present invention relates to a kind of metal cleaning technique, especially a kind of surface of metal product cleaning procedure.
Background technology
Metal-working industry cleaning technique be for before and after all kinds of workpiece of intermetallic composite coating, shape extrusion or enter metallic surface pre-process and post-process and seal up for safekeeping antirust before surface cleaning, also comprise simultaneously to for intermetallic composite coating equipment as before the container of all kinds of lathe, mould, steel rolling equipment and storage transmission lubricating oil thereof, pipeline start and maintenance time cleaning.Cleaning object is metallic surface, the slushing oil that the lubricant that cleaning dirt is residual after mainly intermetallic composite coating comprises machining and forming process or equipment, workpiece use when sealing up for safekeeping.
In recent years, China constantly carries out industrial upgrading, application novel material, novel process, new installation, workpiece cleanliness is comprised to cleaning performance, cleaning efficiency and time, the corrosion inhibiting ability of the non-ferrous metals such as material especially aluminium alloy is had higher requirement, traditional cleaning metal surface adopts scavenging solution to soak its surface, and then scrub, such process is comparatively complicated, the time simultaneously consumed is more, the manpower of meeting at substantial in cleaning process, make the production cost of enterprise higher, therefore the technology being badly in need of a kind of improvement solves above-mentioned technological deficiency.
Summary of the invention
The invention provides a kind of surface of metal product cleaning procedure.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A kind of surface of metal product cleaning procedure, cleaning is:
(1) high pressure water cleaning, uses high pressure water jets to be mapped to surface of metal product, is removed by the foul of its surface attachment;
(2) scrub, use brush to scrub surface of metal product;
(3) high pressure water cleaning, reuses high pressure water jets and is mapped to metallic surface, is rinsed the metal products scrubbed in step (2);
(4) pickling, puts into acid cleaning tank by cleaned metal products in step (3) and carries out pickling;
(5) dry, the metal products of pickling in step (4) is put into drying baker and dries;
(6) check, testing to entering the metal products of drying in step (5), and checking its surface cleaning situation, and to unacceptable product repeated washing step.
Described acid pickling step is:
(1) water washed metal products is positioned in acid cleaning tank, and soaks 1-2 minutes in acid solution;
(2) metal products is unsettled, use atomization hot acid liquid to clean it;
(3) the cold acid solution of high pressure is used to rinse metal products;
(4) dry, the acid solution of surface of metal product being adhered to dries;
(5) dry, air metal products being placed in warm dried and clean dries.
Described acid solution is hydrochloric acid soln, and its hydrochloric acid mass content is 20%-30%.
The temperature of described hot acid liquid is 60-80 degree Celsius.
The invention has the beneficial effects as follows: cleaning process is comparatively simple, and cleaning performance is good, can be applied to automated cleaning equipment, greatly reduces the manpower consumed in cleaning process, reduces enterprise's production cost, be easy to promote.
