Description
Technical field
The present invention relates to laser cleaning field, more particularly to a kind of laser cleaner and cleaning method.
Background technology
Substantial amounts of impurity, such as Fe for being produced in the hot rolled steel plate operation of rolling can be produced in the process of workpiece3O4
Black oxide film, and for Fe3O4Cleaned more than black oxide film by the way of acid solution cleaning, i.e., using hydrochloric or phosphorus
The solution of sour chromic anhydride is cleaned, but this cleaning way can cause service efficiency low because of acid solution volatilization, cost increase, and
And the acid solution that cleaning is used causes severe contamination to environment and corrosion is caused to equipment, also needs to carry out liquid waste processing after cleaning,
Further cost is cleaned in lifting, moreover, the technique of hot rolled steel plate acid solution cleaning was needed by 1~2 minute, and it is heavy afterwards
Liquid waste processing work.
Also there are many researchs improving the mode of acid solution cleaning at present, for example, Application No. CN200410027206.X
Hot-rolling steel plate cleaning agent, hot rolled steel plate is cleaned using the chemical reagent of different formulations, the cleaning agent using sulfuric acid (ratio
Weigh 1.84) 15%~28% chlorion, water 32~71%, total acidity be 40~60 points, operating temperature be 20~80 degrees Celsius,
Effectively it can be cleaned instead of concentrated hydrochloric acid, wherein chlorion can be to obtain in the chlorides such as lithium chloride, sodium chloride, ammonium chloride, hydrochloric acid
.The pernicious gas such as hydrogen chloride of cleaning agent volatile quantity reduces more than 80%, improves environmental pollution, extends the use of equipment
Life-span；Application No. CN201010227925.1, a kind of acid washing method of hot rolling two-phase stainless steel plate, using double nitration mixture pickling,
HNO is used in pre- pickling and final pickling Duan Jun3+ HF mixed solutions carry out pickling；Wherein, in pre- pickling stages, pre- pickle：
HNO3, 140~180g/l；HF, 80~100g/l；Metal ion content in acid：5~40g/l；In final pickling stages, finally
Pickle：HNO3, 200~280g/l；HF, 55~75g/l；Metal ion content in acid：5~40g/l；Steel plate passes through pre- pickling
Time with final acid cleaning process section is 11.3~34 minutes.The present invention can contract the online pickling cadence time of every block of steel plate
It is as short as within 10min, production efficiency is greatly improved, coil pickled surface quality meets scene and user requires that steel plate is in roller-way
On be continuously advanced, without swinging back and forth, and eliminate special Passivation Treatment process, significantly reduce production cost；But
There are still cleaning process needs, time-consuming and needs to carry out sour night cleaning, it is necessary to which a large amount of chemical reagent, production cost is high
Shortcoming.
