Description
Technical field
The present invention relates to the cleaning metal surface technical field, particularly, the present invention relates to a kind of Novel metal plate belt surface cleaning method and device, described metal plate and belt method for cleaning surface and device utilization infiltrate in the abrasive slurry pond arranges up and down, and carry out pressure contact with the grinding face of certain pressure and the upper and lower surface of metal plate and belt, synergy by abrasive slurry and pressure surface, guarantee that metal plate and belt can realize the removing of surface attachments after the grinding face by with its upper and lower pressure contact in surface, guarantee that surface when metal enters next PROCESS FOR TREATMENT flow process keeps clean enough, effectively improve finished surface quality and the efficiency of post treatment of metal.
Background technology
The metal material such as steel, alloy, in hot rolling or heat treatment process, can form the fine and close covering that one deck is comprised of metal oxide on surface, be commonly called as " firecoat ", and the existence of this firecoat can impact further processing processing:
Make on the one hand the surface crack of material be difficult for being found in advance, thereby make the finished product processed have quality problems; Easily firecoat is pressed into to metal surface on the other hand, causes surface quality problems; In addition, the existence of hard oxide, can accelerate the wearing and tearing of roll or drawbench.Therefore entering the front metal plate and belt surface firecoat removing step of cold-rolling mill is one of operation indispensable on cold rolling product line.
In order to eliminate the impact of oxide on the metal plate and belt cold-rolled quality, at present, the cold rolling product line of metal plate and belt all adopts the processing mode of descaling bath to come clean metal strip surface both at home and abroad, as generally adopted at present the Acidwash solution of sulfuric acid, hydrochloric acid and hydrofluoric acid, oxide (being commonly called as " de-scaling ") and other attachments on the chemical reaction dissolution of metals surface by acid tank inside.The cold rolling product line of current main flow the most is all with the acid cleaning process link, so continuous cold rolling produces line also referred to as sour rolling line.
The acid mist produced because of the Pickling Descaling process section in sour rolling line produces serious pollution to surrounding enviroment, and this makes sour rolling line high to the production facility requirement for anticorrosion; The acid solution processing cost of its discharge simultaneously is higher, in the acid regeneration process, can produce a large amount of sewage, directly environment is caused to severe contamination.In addition, adopt Pickling Descaling easily to cause de-scaling inhomogeneous, and metal loss is large.
The problem of environmental pollution caused in order to solve pickling, researcher has carried out a large amount of research, multiple technologies and equipment have been developed, remove the firecoat of metal surface to substitute pickling, grind as electrolysis de-scaling, electrolysis and eliminate squama, electric discharge de-scaling, electron beam de-scaling, laser de-scaling, grind the descaling method of de-scaling, liquid rotoblasting (claiming again the high pressure liquid sandblast de-scaling), ball blast de-scaling, alternating bending de-scaling and the combination of above-mentioned distinct methods, but all these new methods or technique all can't substitute the continuous acid-washing groove on existing cold rolling product line.
Based on this, the domestic layout of the new technology for this de-scaling aspect does not also have the innovation and creation that can consult, mainly also rests on local updating to external wet chemical surface cleaning apparatus, transformation etc.
Japan JP06108277A discloses and adopted spray acid and the descaling process that brush roll is used in combination on the continuous cold rolling line, utilizes this combination to replace existing descaling bath technique.Because this mode is still wanted a large amount of use acid solutions, simultaneously to spray sour nozzle etc. require very strict, the pollution problem that does not therefore fundamentally solve cold rolling product line.Japanese JP55034688A discloses a kind of associating PV rolling scale breading-compound abrasive high-pressure spray de-scaling mode in addition, compound abrasive high-pressure spray de-scaling cell layout has 4 of series connection form, the anacidity de-scaling of realization to cold conditions band steel, yet, this mode must adopt a large amount of tiny abrasive materials, and abrasive material supplement, detect and with separating of firecoat mixture etc. technical difficulty all very high, the realistic meaning of realization is less; After Japanese JP57142710A discloses the first roll extrusion of a kind of employing simultaneously, the mode of recycling brush roll-high-pressure water jet is carried out de-scaling to the high temperature hot rolled plate, and its de-scaling rate reaches 80%, then continues to adopt traditional final de-scaling of pickling mode.Again, Japan JP57068217A discloses a kind of hot-rolling metal of the cold conditions for cold rolling entrance strip cal rolling, adopt heavy reduction rate 4%～40%, realize scale breading, loose squama, follow-up immediately following high-pressure spray processing (0～150kg/cm2), the metal plate and belt after so processing can carry out curling delivery or directly enter cold-rolling mill carrying out cold rolling.Simultaneously, Japanese JP59097711A discloses a kind of compressed air+abrasive material of high pressure that adopts and has carried out the mixing jetting descaling method, makes the clearance rate of the method up to " 65～95% ".
In addition, the material manufacture work of the U.S. (being called for short TMW company) discloses a series of for metal plate and belt surface clean technology after calendar year 2001.Such as US20080108281 (A1), US20080182486 (A1) and US20090227184 (A1) etc., all disclose a kind of abrasive material and mixed mud of water of utilizing and carried out jet cleaning, yet, due to this mode run into equally abrasive material and firecoat minute, abrasive wear detection technique and automatically supplement the technical bottleneck such as technology, therefore be difficult to realize.In addition, the US5388602 high pressure water jet cleaning device of West Europe Danieli company application, carry out de-scaling mainly for various continuous casting billet, can't meet cold rolling requirement.On the other hand, Japan Patent JP05092231A, JP09085329A and JP2002102915 etc., its application occasion that adopts the high-pressure water jet de-scaling is only the forging base during hot steel billet or forging.
In addition, for solving the metal plate and belt surface attachments, usually adopt the mode of brush roll to be removed both at home and abroad.As 3M company is designed with a kind of brush roll with bristle, every bristle surface all is stained with a plurality of hard particles things, as SiC particle, brown corundum etc., be used for the removing effect that realizes rolling while scrubbing in brush roll and metal plate and belt surface, yet the hard particles thing that bristle surface adheres to easily comes off, and directly affects the result of use stability of brush roll.China Qianshan Basin, anhui brush roll factory is processed with the multiple hard brush roll brushed for metal plate and belt surface firecoat, its bristle is generally anti abrasive rigid etc., the brush roll of this form is because directly brushed with steel wire, its roughness of scrubbing rear plate face is large, and the uniformity of removing is difficult to be guaranteed.
