Description
Technical field
The present invention relates to the steel alloy production technical field, belong to the working method of structure, be specially the working method of the structure of ys >=550MPa with colour coated plate with the color coating slab.
Background technology
China's colour coated plate is mainly used in building field, and wherein the ratio of sandwich board and corrugated panel has just accounted for about 85% of colour coated plate for building, and require to have HS, good toughness and superior corrosion resistance.Domestic many users (particularly construction industry user) need structure with the intensity of colour coated plate with the raising structural part, and weight reduction reduces cost.
Through document resource both domestic and external is retrieved; Find one Chinese patent application number for CN99810709.3, by B En Geer; KD is grace suddenly; The patent documentation of " a kind of method of making cold-strip or sheet material " of KD Shi Mite invention, its relate to by C, Al, Ti, V, Nb be at most respectively 0.2% and Si, Mn be at most respectively 1% and the boron (＞0.78 * N) of fixed nitrogen aequum; All the other low alloy steel that consist of iron and unavoidable impurities are made the method for cold-strip or sheet material, and cold-strip makes perfect recrystallization 520～780 ℃ of sufficiently long for some time of lower annealing temperature.This patent documentation is a kind of cold-rolled steel sheet of accomplishing recrystallize, and is different with metallographic structure of the present invention, and the plate property that causes is different.Other has number of patent application: the Chinese patent document of CN200810180707.X, its disclosed this hot-dip coating aluminium-zinc alloy steel plate comprise substrate of steel plate and the al-zn alloy coating that is positioned at substrate of steel plate surface, are benchmark with the total amount of substrate of steel plate; This substrate of steel plate contains (weight percent) greater than 0.03% to 0.1%C, 0.15～0.35%Mn, 0.001～0.02%Ti; 0.005～0.03%Nb, 0.01～0.065%Als, 99.44～99.8%Fe; Si≤0.03%; P≤0.025%, S≤0.015%, N≤0.005%; The weight of its said al-zn alloy coating is 70～100g/m
2, the content of aluminium can be 50～65wt% in the al-zn alloy coating, the content of zinc is 35～50wt%; The thickness of this invention be 1.5 millimeters hot-dip coating aluminium-zinc alloy steel plate ys (ReL) up to 420MPa, tensile strength (Rm) up to 460MPa, the tensile strength of this steel plate is lower than 540MPa, it is because alloy amounts such as the Ti that in steel, adds, Nb are high; Cause production cost high; Therefore, then the market competitiveness is poor to make precoated substrate with this type high strength galvanized steel plate, is difficult to apply.
Development along with the colour coated plate technology; Progressively begin to consider Eco-power structure is applied in the colour coated plate as substrate with the plate golding aluminium zinc alloy plate; But still the deficiency that exists is: in order to guarantee the HS of structure with the color coating base material; Usually in steel, added more alloying element, but after having added more alloying element in the steel, improved the production cost of structure on the one hand with colour coated plate; On the other hand; In the alloying element that in HS precoated layer steel, adds (like Mn, Si, Al, Cr, P, Ti, Nb, Mo etc.); Be prone at surface enrichment in the cold rolling recrystallization annealing process of some element (like Mn, Si, Ti, Nb, Al etc.) before galvanizing; Generate the thin sull of one deck, reduced the sticking power of zinc coating, cause the solidity to corrosion of colour coated plate to descend.Therefore, both at home and abroad the researchist is devoted to develop a kind of structure that has low cost, HS, excellent corrosion resistance simultaneously always and uses colour coated plate.
In the prior art; Adopt continuous annealing furnace carry out the annealed temperature general all 680 ℃ and more than; The highest reaches 780 ℃; The deficiency of its existence is: after continuous annealing, the metallographic structure of steel plate is ferritic+perlite or ferritic+free cementite, or ferritic+perlite+small-amount free cementite.Such metallographic structure meeting cause its ys do not reach 550MPa and more than, thereby can not be used for the special occasions that automobile refrigerated tank, arch covering etc. need high-yield strength.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; It is that ferritic+deformation bands is brilliant that a kind of metallographic structure after continuous annealing is provided; To improve ys at 550～600MPa; Can satisfy the special occasions that is used for needs high-yield strengths such as automobile refrigerated tank, arch covering, and technology is simple, structure easy to implement is with the working method of colour coated plate.
Realize the measure of above-mentioned purpose:
The structure of ys >=550MPa is with the working method of colour coated plate, its step:
1) smelt: carry out desulfurizing iron, converter smelting, continuous casting and become component and weight percent to be: C:0.03%～0.05%, Si :≤0.02%, Mn:0.15%～0.25%; P :≤0.015%, S :≤0.012%, Als:0.02%～0.06%; N :≤0.005%; Ti :≤0.005%, Nb :≤0.0045%, all the other are the continuously cast bloom and the hot rolling of Fe and inevitable impurity;
2) carry out pickling;
3) carry out cold rollingly, control accumulative total draft is 55～65%;
4) carry out continuous annealing, annealing temperature is controlled at 600 ℃～650 ℃, and annealing time was at 20～60 seconds; After annealing, requiring its metallographic structure is that ferritic+deformation bands is brilliant; Described deformation bands crystalline substance refers to not accomplish the banded structure of recrystallize;
5) carry out hot-dip aluminizing zinc, controlling two-sided hot-dip aluminizing zinc metal level weight is 60～150g/m
2, the component of its coating and weight percent are: Al:49%～60%, and Zn:38%～50%, Si:1%～2%, and the temperature that control band steel gets into the zinc pot is at 600 ℃～630 ℃, the temperature of control aluminium zinc liquid is at 570 ℃～590 ℃;
6) carry out polishing, straightening, color coating, packaging process and for use.
Structure of the present invention uses the thickness of colour coated plate to be 0.6mm～1.5mm, and two-sided hot-dip coating aluminium-zinc alloy coating weight is 60～150g/m
2, the content of Al is 49～60% in the coating; The content of Zn is 38～50%, and the content of Si is 1～2%.Characteristics of the present invention just are through annealing temperature to be 600～650 ℃ continuous annealing, and in annealing time was 20～60 seconds scopes, making its metallographic structure was ferritic+deformation bands brilliant (recrystallize is also accomplished).Thereby make it composition simple (not adding Ti, Nb), under the also less condition of the Mn alloy amount of adding, its ys R
