Description
Technical field
The present invention relates to laser cleaning field, in particular to a kind of laser cleaner and cleaning method.
Background technique
A large amount of impurity, such as the Fe for generating in the hot rolled steel plate operation of rolling can be generated in the process of workpiece3O4
Black oxide film, and it is directed to Fe3O4The mode that black oxide film mostly uses acid solution to clean is cleaned, that is, uses 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 uses causes seriously to pollute and causes to corrode to equipment to environment, also needs to carry out liquid waste processing after cleaning,
Cleaning cost is further promoted, moreover, the process requirement of hot rolled steel plate acid solution cleaning is passed through 1~2 minute, and heavy later
Liquid waste processing work.
Also there is many research in the mode for improving acid solution cleaning at present, for example, application No. is 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
1.84) 15%~28% chloride ion, water 32~71% are weighed, total acidity is 40~60 points, and operating temperature is 20~80 degrees Celsius,
It can effectively be cleaned instead of concentrated hydrochloric acid, wherein chloride ion can be to obtain in the chlorides such as lithium chloride, sodium chloride, ammonium chloride, hydrochloric acid
?.The pernicious gases volatile quantity such as hydrogen chloride of the cleaning agent reduces 80% or more, improves environmental pollution, extends the use of equipment
Service life；Application No. is CN201010227925.1, a kind of acid washing method of hot rolling two-phase stainless steel plate, using double nitration mixture pickling,
HNO is all made of in pre- pickling and final pickling section3+ HF mixed solution carries out pickling；Wherein, in pre- pickling stages, pre- pickling solution:
HNO3, 140~180g/l；HF, 80~100g/l；Metal ion content in acid: 5~40g/l；In final pickling stages, finally
Pickling solution: 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, and 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, needs a large amount of chemical reagent, high production cost
Disadvantage.
Laser cleaning is a kind of new and effective Environment protection cleaning technology, can be removed using the directionality and high brightness of laser
Fall the pollutant of material surface.A kind of cleaning technique of the laser cleaning as novel high-efficiency environment friendly, at this stage, there are also use
Laser cleaning cleans the research of hot rolled steel plate, for example, application number CN201610167791.6, a kind of ultra-short pulse laser galvanometer
The method of formula scanning removal hot rolled steel plate coating, comprising the following steps: 1): to the hot-rolled steel with Al-Si coating to be welded
The surface of plate is cleaned；2): the hot rolled steel plate after cleaning being fixed on frock clamp, the ultrashort arteries and veins that laser issues is adjusted
Impulse light is arranged perpendicular to hot rolled steel plate；3): joining according to the technique of preset ultra-short pulse laser mirror-vibrating removal Al-Si coating
Number is opened laser and is removed to the Al-Si coating of hot rolled steel plate；4): closing laser, remove Al-Si coating hot-rolled steel
Plate completes the process of the Al-Si coating of removal hot rolled steel plate.Method of the invention is swept without light-dividing device, mirror-vibrating
It is larger to retouch method energy density, removal efficiency is high, goes the dimension adjustable of removing coating, and can be by controlling laser power control
It removes thickness, but cannot achieve the high-efficiency washing on hot-rolled steel production line to hot rolled steel plate.
