Abstract
This invention relates to a bonding process of non-corrosive steel carbon steel sandwich, which comprises the following steps: a) acid cleaning and derusting the carbon steel plate, surface cleaning the non-corrosive steel at the same time; b) bushing high-intensity adhesive on the surface of carbon steel plate or non-corrosive steel, and sticking them together; c) extruding the adhered non-corrosive steel and carbon steel plate, making them stick to sandwich; d) extruding the sandwich with planisher, and then cleaning excess adhesive dirt; e) forming roll bending type with rolling machine ,or forming plate type with guillotine.
Description
Technical field
The present invention relates to metal reprocessing technical field, especially with two kinds of sheet metals compound be the processing method of one.
Background technique
At present, resultant metal outer casing, decorative appearance, railing tube, Anti-theft door and window all adopt stainless steel and carbon steel composite plate.Still price is cheaply more not a lot of than pure corrosion resistant plate for the advantage of this composite sheet, and keeping on the rakish basis of corrosion resistant plate, has increased intensity, has enlarged using scope.
The production method of stainless steel and carbon steel composite plate also has only two kinds at present.First method is the rolling that the Zhuhai City, Guangdong Province extra large special steel of sun Co., Ltd adopts: at first the corrosion resistant plate with 0.5 millimeters thick is cut into platelet, on platelet, apply medium and oven dry that one deck is Main Ingredients and Appearance with graphite, again the carbon steel board of 6～8 millimeters thick is cut into platelet and derusts polishing; Then two corrosion resistant plates and two carbon steel board are superimposed together, form a carbon steel board, corrosion resistant plate, graphite medium, corrosion resistant plate, the superimposed body of carbon steel board, and around superimposed body, upper and lower carbon steel board welding is formed the mixing base substrate.To mix base substrate heating hot rolling at last.Under the effect of hot rolling pressure, to mix base substrate and will extend about seven times, will combine closely with the carbon steel board surface in the corrosion resistant plate surface that does not apply the graphite medium, form two stainless steel and carbon steel composite plates.Ensuing operation is toe around cutting off, separate two stainless steel and carbon steel composite plates, graphite medium, cold rolling, smooth, polishing are once more removed in cold rolled annealed, pickling.The advantage of rolling is two kinds, and the sheet metals combination is tight, adhesive strength is high.Deficiency is that hot-rolled process makes the corrosion resistant plate distortion, needs multiple tracks subsequent machining technologies such as increase is cold rolling, pickling graphite medium, polishing, the production process complexity, operation is many, cost of production is high, the stainless steel lining became uneven is even, the surface is prone to pin hole, the thinnest corrosion resistant plate that can only compound 0.07 millimeters thick.
Second method is the explosion method that Wuhan Iron and Steel Company adopts: be about to thick corrosion resistant plate and the carbon steel board of 2 millimeter and fit tightly together, another side on corrosion resistant plate and carbon iron plate is put explosive, and the impact force of utilizing explosive charge to produce makes the corrosion resistant plate and the carbon steel board extruding that fit together be combined into composite sheet.The advantage of explosion method also is two kinds, and the sheet metals combination is tight, adhesive strength is high.The distortion of the corrosion resistant plate of deficiency is big, need polishing treatment again and befouling environment, easily go out security incident, product specification is few, can only the thick corrosion resistant plate of compound 2 millimeter, can not satisfy many specification requirements of user.
Summary of the invention
The purpose of this invention is to provide a kind of process for bonding stainless steel and carbon steel composite plate, under the prerequisite that guarantees the corrosion resistant plate appearance quality, accomplish that product specification is many, applied widely, production technology is simple, reduces production costs, energy saving, safe and reliable and good environmental protection.
The production stage of mull technique is as follows:
1, cleaning: carbon steel board is carried out pickling derust, extract with cleaning surfaces and handle, simultaneously corrosion resistant plate is carried out cleaning surfaces and handle.
2, brush coating is fitted: carbon steel board or corrosion resistant plate external coating high-strength structureal adhesives handling through cleaning surfaces fit together both.
3, extrusion bonded: corrosion resistant plate and carbon steel board with the rubber roll extruding fits together make it be bonded into composite sheet.
4, smooth removing contamination: push stainless steel and carbon steel composite plate with leveler, remove unnecessary tackiness agent dirt subsequently.
5, system volume or shear: be rolled into the roll bending shape or be cut into plate-like finished product with cut-off machine with plate bending rolls.
Because applications such as the resultant metal outer casing of use stainless steel and carbon steel composite plate, decorative appearance, railing tube, Anti-theft door and window require not too high to the adhesive strength of two kinds of sheet metals, therefore only require that two kinds of sheet metals in use are that an integral body is just passable, the combined strength bination of the stainless steel and carbon steel composite plate of producing with mull technique satisfies the needs of application fully.
Compared with the prior art, the present invention has following advantage:
1, kept the glossy characteristic attractive in appearance in corrosion resistant plate surface in the production process, corrosion resistant plate is undeformed, does not need to polish again.
2, the present invention can produce stainless steel and carbon steel composite plate less than 0.07 millimeter corrosion resistant plate with thickness, and promptly the consumption of corrosion resistant plate can drop to minimumly in composite sheet, therefore greatly reduces cost of production.
3, product specification is many, satisfies various needs of users.The present invention not only can also produce stainless steel and carbon steel composite plate greater than 2 millimeters corrosion resistant plate with thickness with the corrosion resistant plate of thickness less than 0.07 millimeter, can produce the composite sheet of any specification according to user's needs.
4, few, energy saving, handling safety of operation, reduced pollution factor to environment, help environmental protection.
Specific implementation method
Embodiment one
Production stage as mentioned above, the detergent that only is to use is that dilute sulfuric acid, detergent are that alcohol, tackiness agent are that 502 cyano group third are rare.
Embodiment two
Production stage is identical with example one, and the detergent that difference is to use is that watery hydrochloric acid, detergent are that acetone, tackiness agent are 410 instant drying adhesives.
Embodiment three
Production stage is identical with example one, and the detergent that difference is to use is that rare nitric acid, detergent are 4110 instant drying adhesives for common washing agent, the tackiness agent of selling on the market.
Embodiment four
Production stage is identical with example one or example two, and not existing together is that tackiness agent is 330 non-mixglues.
