Abstract
The utility model discloses a steel strip structure improving the adhesive power between the steel surface and the hot-dip zinc/aluminum /zinc aluminum coated layer, which comprises a steel basal body, an extremely thin nickel electric plating layer adsorbing on the outer surface of the steel basal body, a hot-dip zinc /aluminum /zinc aluminum coated layer absorbing on the outer surface of the nickel electric plating layer. The steel strip structure is not only capable of improving the adhesive power between the steel surface and the hot-dip zinc /aluminum /zinc aluminum coated layer, which avoids the crack and peel of the coating layer caused by the imperfect adhesiveness directly affecting the zinc coating product quality, but also can not increase cost because of the relatively high energy consumption induced by the hot-dip zinc /aluminum /zinc aluminum coating process art.
Description
Technical field
The utility model belongs to the steel plate processing technique field, particularly relates to a kind of band steel structure that improves galvanizing/aluminium/aluminium zinc layer and steel surface adhesion force.
Background technology
The band steel also is steel band, is actually the sheet metal of long and narrow and rolling supply, and why the band steel will carry out zinc-plated or aluminize or the processing of aluminum-zinc alloy, is because of after being coated with zinc layer or aluminium lamination or aluminium zinc layer, and that steel matrix can obtain is antirust, effective protection of corrosion protection.Such as adopting zinc-plated mode; because the chemical property of zinc is more active; in the air at normal temperatures; can with airborne water, carbon dioxide and oxygen generation chemical reaction; generate the thin and fine and close basic zinc carbonate film of one deck, this layer zinc oxide has just stoped the further oxidation of inner zinc, around this principle; people protect iron not corroded with zinc, prolong the band steel purpose in service life thereby reached.In existing zincincation, galvanizing by dipping is a kind of cost-effective surface of steel plate anticorrosion technology, characteristics such as that hot-dip galvanized steel strip has is antiacid, antirust, corrosion protection, service life is long, material is light, outward appearance is beautiful simultaneously, glossy, thereby gain great popularity, be widely used in numerous areas such as household electrical appliances, automobile, office machine, steel part furniture, electronic equipment, building.
The band steel continuous hot galvanizing production of prior art be with the band steel through shear end to end, after welding and the Chemical cleaning degreasing, enter continuous annealing furnace and carry out the recrystallization annealing processing, and plate face oxide layer is reduced into active pure iron layer, enter the zinc pot then in confined conditions and carry out galvanizing, behind the strip steel Zn-plating, improve plate shape through polishing machine, seven-roll Abramsen machine, and handle, enter coiling machine at last through chromic acid passivation or oil surface.In fact above-mentioned band steel continuous hot galvanizing production process has comprised pretreatment procedure, the annealing in process operation, zinc-plated operation and postprocessing working procedures, wherein zinc-plated operation will immerse in the zinc pot of fusion with steel, make its surface adhesion one deck zinc, therefore after above-mentioned galvanizing by dipping treatment process is handled, the structure of band steel just comprised base steel layer 1 ' and its surperficial zinc coat 3 ', Fig. 1 is the cross-sectional configuration schematic diagram of existing band steel, steel matrix 1 ' just because of there being zinc coat 3 ' just make band steel to have stronger corrosion resistance, thereby plating adhesion is the primary capability and performance index of galvanizing product, plating adhesion not good general causes coating to crack and comes off, and directly influences the galvanizing production quality.The raising hot galvanized layer of prior art and the mode of steel surface adhesion force are in the galvanizer program process, in zinc liquid, add nickel, utilize the zinc-nickel molten metal bath to make the steel matrix surface obtain one deck Zinc-Nickel coating layer, plating adhesion is obviously improved, still, because the fusing point of zinc is 419.5 ℃, the fusing point of nickel is 1455 ℃, thereby adopt the Zinc-Nickel coating layer technology mode to have brought difficulty for zinc-plated operation, simultaneously, also make zinc-plated operation produce huge energy consumption because of the fusing point of nickel is too high.
