Description
Technical field
The present invention relates to the cleaning metal surface technical field, particularly, the present invention relates to a kind of cold conditions metal plate and belt surface solid jet descaling system and method, described cold conditions metal plate and belt surface solid jet descaling system and method, be mainly used in realizing that the positive and negative to the cold conditions metal plate and belt carries out the de-scaling of continuity jet, the positive and negative that simultaneously guarantees the metal plate and belt after the jet de-scaling is not only fully residual without firecoat, guarantee simultaneously positive and negative can be all the time dry, clean enter next step process section.
Background technology
Metal material can form the fine and close covering that one deck is comprised of metal oxide in hot rolling or heat treatment process on surface, be commonly called as " firecoat ".The existence of this firecoat can cause impact as described below to 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; On the other hand, easily firecoat is pressed into to metal surface, causes surface quality problems.In addition, the existence of hard oxide also can be accelerated the wearing and tearing of roll or drawbench.Therefore entering the front surface of steel plate firecoat removing step of cold-rolling mill is one of operation indispensable on cold rolling product line.
Impact for above-mentioned surperficial firecoat on metal material, the processing mode that manufacturing enterprise all adopts wet chemical to be cleaned is at present both at home and abroad removed the firecoat that adheres on metal plate and belt surface.For steel plate, it adopts the strongly acidic solution of sulfuric acid, hydrochloric acid and hydrofluoric acid usually.The production environment very severe of this wet chemical acid cleaning process, and must carry out the circular regeneration processing to a large amount of residual acid produced because produce, current described circular regeneration technique also certainly leads to corresponding toxic emission, contain a large amount of acidity, corrosivity composition in the waste gas of its discharge, as HCL, SO2 etc., direct atmosphere pollution.
Based on this, clean for solving above-mentioned chemical method the serious problem of environmental pollution brought, researcher has carried out a large amount of research, has developed multiple technologies, removes the firecoat of metal surface to substitute this chemical method.As the electrolysis de-scaling, as described in method comprise, for example, electrolysis is ground and is eliminated squama, electric discharge de-scaling, electron beam de-scaling, laser de-scaling, grinds the descaling method of de-scaling, ball blast de-scaling, alternating bending de-scaling and the combination of above-mentioned distinct methods.Wherein especially with fastest developing speed with the high-pressure spray technique of scale removal, its process of industrialization is also obvious all the more.
Yet this jetting method is because distinctive de-scaling mode, cause the firecoat surface after this method de-scaling also to have following subject matter:
1) because jet directly carries out the de-scaling processing with metal plate, and the plate face is shaken, the inhomogeneous etc. of firecoat tissue all can directly be caused inconsistent to plate face scale removal effect of jet;
2) de-scaling speed is slower, can't realize revolutionary raising;
By consulting Patents, also find abroad especially Japan, the metallurgical technology developed countries such as Germany, although it has proposed numerous relevant solid jets, the patent of polish-brush technique of scale removal or patent application technology, as Japanese JP06108277A discloses the descaling process that adopts spray acid and brush roll to be used in combination on the continuous cold rolling line, Japan JP55034688A discloses a kind of associating PV rolling scale breading-compound abrasive high-pressure spray de-scaling mode, Japan JP57142710A, JP57068217A, Japan JP59097711A, and Canadian TMW company discloses a series of US20080108281 of the clearance technique for the surface of steel plate firecoat (A1) after calendar year 2001, US20080182486 (A1) and US20090227184 (A1) etc., in addition, as U.S. US5388602, day JP05092231A of the present invention, the patent such as JP09085329A and JP2002102915 or patent application technical scheme, but remain in the part that has much room for improvement aspect the processing validity of the metal plate after processing the jet de-scaling.
