Abstract

A metal surface cleaning method is characterized by comprising the following steps: (1), removing impurities on the surface of a workpiece, polishing and removing burrs; (2), washing the surface of the workpiece through high-pressure water in a spraying manner; (3), carrying out heat treatment on the workpiece, and wiping the workpiece after cooling; (4), putting the workpiece into cleaning liquid and stirring the cleaning liquid; (5), putting the workpiece into an ultrasonic cleaning machine for ultrasonic cleaning; (6), washing the workpiece by high-pressure water; (7), drying by isolating oxygen. The metal surface cleaning method has the benefits as follows: the process step is simple and convenient, energy consumed in an operation process is less, the dosage of a cleaning agent is less, the cleaning efficiency is high, the cleaning effect is good and popularization is facilitated.

Description

A kind of cleaning metal surface method

Technical field

The present invention relates to a kind of cleaning metal surface method.

Background technology

Metal-working industry cleaning technique to refer to before and after all kinds of workpiece to intermetallic composite coating, shape extrusion or before and after metal finishing and seal up for safekeeping antirust before surface cleaning, also comprise simultaneously to for intermetallic composite coating equipment as lathe, mould, steel rolling equipment and storage thereof transmit the ventilation of lubricating fluid, pipeline start before and maintenance time cleaning.Cleaning object is metallic surface, and the lubricant that cleaning dirt is residual after mainly intermetallic composite coating comprises machining and forming process or equipment, workpiece seal the slushing oil had constantly up for safekeeping.The object of cleaning is removed by metallic surface dirt under specific time and processing condition, do not damage metallic surface, can meet frighten operation as electroplated, spraying paint, the requirement such as assembling.Along with the fast development of Chinese manufacturing, more and more higher to the requirement of cleaning technique, the consumption of clean-out system is increasing, defines the market scale that year consumes few hundred thousand tonnes of.Due to the singularity of cleaning object, cleaning dirt, cleaning and cleaning requirement, determine metal cleaning and be different from general matting and pressure release surface cleaning.This year, China constantly carries out industrial upgrading, application material, novel process, new installation, cleaning performance is comprised workpiece cleanliness, cleaning efficiency, had higher requirement to the corrosion inhibiting ability of material especially steel, especially energy-saving and emission-reduction policy real-time, and following customer service Foreign Green trade barrier, cleaning technique is just towards energy-efficient, environmental protection development, cleaning machine used is also doing lasting improvement, and scavenging mechanism constantly has new discovery and is applied.

Presently used main wash method is still larger to the consumption of clean-out system, cleaning efficiency is slower, and cleaning performance often once can not reach requirement, resource and the energy cause certain waste, the technology being therefore badly in need of a kind of improvement solves above-mentioned technological deficiency.

Summary of the invention

The invention provides a kind of cleaning metal surface method.

The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:

A kind of cleaning metal surface method, comprises the following steps:

(1) by the Impurity removal of workpiece surface, polish and remove deburring;

(2) with high pressure water hydro-peening workpiece surface;

(3) workpiece is heat-treated, with wet cloth wiping workpiece after cooling;

(4) workpiece is put into scavenging solution, and stirring and washing liquid;

(5) workpiece is put into Ultrasonic Cleaners and carry out ultrasonic cleaning;

(6) high pressure water rinses workpiece;

(7) oxygen barrier is dried.

Thermal treatment temp is 400-500 DEG C, atmospheric environment, and the time length is 20-45min.

Described scavenging solution is sodium hydroxide solution, and in solution, sodium hydroxide mass percent is 12-18%.

The invention has the beneficial effects as follows: processing step is simple and convenient, the energy consumed in operation is less, and the consumption of clean-out system is less, and cleaning efficiency is high, and cleaning performance is good, is easy to promote.
