Abstract
The invention discloses a kind of strong zinc-aluminum-magnesium clad steel sheet of high-temperature molding superelevation and its manufacturing methods, steel plate includes following chemical component and its weight percent: C:0.2~0.8%, Si:0.08~0.6%, Mn:1.5~5.0%, Al≤0.08%, N≤0.005%, remaining is Fe and inevitable impurity；Coating includes following chemical component and its weight percent: Al:1.5~20%, and Mg:1.3~7%, remaining is Zn and inevitable impurity.The strong zinc-aluminum-magnesium clad steel sheet of hot forming superelevation produced by the present invention, tensile strength >=1700MPa after meeting substrate hot forming, under the premise of elongation after fracture >=5%, coating is continuous whole after being heated at high temperature punch forming, without the crackle for extending to matrix；Zn content is integrally higher than 30% in coating alloy phase, and coating corrosion resistance is excellent；Steel of the present invention is able to satisfy corrosion-proof and high-strength degree Automobile Plate lightweight demand.
Description
Technical field
The present invention relates to metallurgical hot extrusion briquetting techniques, in particular to a kind of strong zinc-aluminum-magnesium clad steel sheet of high-temperature molding superelevation
And its manufacturing method.
Background technique
In recent years, the market demand of automobile thermoformed parts is in explosive growth trend, and thermoformed part is on white body
Application percentage be up to 45%, it is contemplated that the coming five years will double above.In thermoforming technology earlier, the surface of steel plate
It is not handled by coating, a degree of oxidation can occur for surface during thermoforming, generate skin decarburization and oxidation peeling is existing
As reducing production efficiency, the method that chromium shot-peening can be used removes oxide on surface.
With the development of thermoforming technology, coating technology is increasingly being applied to thermoforming steel.Coating can be prevented into
Surface oxidation and decarburization during type, moreover it is possible to the Corrosion Protection after improving paint dress.The heat of different coating has been developed at present
Stamping steel plate, such as: aluminium silicon cladding (Al-10%Si), hot pure zinc plating (GI) coating, kirsite (GA) coating and plating zinc-nickel
(Zn-10%Ni) coating etc..Al-Si coating high temperature resistant, but do not have incision protection performance；Zinc-nickel (Zn-10%Ni) plating is electroplated
Layer has preferable heat-resisting quantity and resistance to incision protection performance, and shortcoming is that price is more expensive, and productivity is low；GI and GA coating
The crackle induction steel matrix cracking easy to form in thermoforming process.Therefore, it is necessary to develop a kind of the novel of high temperature resistant forming
Coating ultra-high strength steel plate meets growing user's use demands.

The mechanism of each element and function analysis are as follows in steel of the present invention:
C: carbon can stable austenite phase, thus reduce Ac3 point, reduce hot-forming temperature, reduce energy consumption, carbon atom exists
Gap solution strengthening effect is played in martensite, it is first much larger than itself and displacement solid solution strengthened alloy to the strengthening effect of martensite
Element, but since thermoformed part requires to be assembled to body of a motor car with the mode of spot welding, in order to meet good welding performance, carbon
Content is limited to 0.2~0.8%.
Si: silicon is solution strengthening element, thus it is possible to vary austenite transformation temperature can also inhibit cementite to be precipitated, and stablize
Austenite, but excessively high silicon can make the oxidation film of surface of steel plate be difficult to remove, and therefore, silicone content is limited to 0.08~0.6%；
Mn: manganese is to improve the most common alloying element of harden ability, makes crack sensitivity due to welding the appearance of hardened layer
Increase, while punching performance reduces, in order to ensure higher punching performance and welding performance, limit manganese content as 1.5~
5.0%, preferred content is 1.8~3.8%.
Al: aluminium plays deoxidation in steel, and should ensure that in steel has a certain amount of dissolved aluminum, otherwise cannot play its effect,
But excessive aluminium can also be such that generation aluminium system in steel is mingled with, and be unfavorable for the smelting and casting of steel, meanwhile, suitable aluminium is added in steel
Nitrogen in steel, oxygen atom can be eliminated to the adverse effect of performance.Therefore, aluminium content is limited to 0.08% or less.
N: nitrogen can form titanium nitride in the steel for adding titanium in conjunction with titanium, and this second phase being precipitated at high temperature is conducive to by force
Change matrix, and improve the welding performance of steel plate, but nitrogen content, higher than 0.005%, the solubility product of nitrogen and titanium is higher, at high temperature
The coarse titanium nitride of particle, the serious plasticity and toughness for damaging steel are formed, in addition, higher nitrogen content need to increase corresponding micro- conjunction
Gold element, to increase cost.Therefore, by Control of Nitrogen Content below 0.005%.
B: minimal amount of boron is added in thermoforming steel to be gathered at austenite grain boundary, postpone ferrite forming core, from rather than
It is often effectively prevented transfer and forms ferrite in forming process, therefore, limit boron content as 0.002~0.01%.
Cr: chromium more effectively improves the harden ability of steel than manganese, and preferably addition content is 0.1~0.8%.
Ti, Nb and V: primarily serving refined crystalline strengthening and precipitation strength effect, and Ti+Nb+V content is no more than 0.2%.
Al in plating solution: when Al content is less than 1.5% in coating, improve that corrosion proof effect is not significant, and Al content is higher than
Bottom ash increases when 20%.Aluminium content is limited as 1.5~20%, preferred content is 1.5~7%.
Mg in plating solution: when Mg content is less than 1.3% in coating, it is not significant to improve corrosion proof effect, and Mg content is higher than 7%
When, top slag increases.When Al/Mg < 1, dross is more, coating surface quality decline.Content of magnesium is limited as 1.5~7%, and Al/Mg
≥1。
Zn in plating solution: in plating solution in addition to alloy Al, Mg, remaining is Zn and inevitable impurity.
Compared with prior art, the invention has the following advantages that
First, the strong zinc-aluminum-magnesium clad steel sheet of hot forming superelevation produced by the present invention, after meeting substrate hot forming
Tensile strength >=1700MPa, under the premise of elongation after fracture >=5%, coating is continuous whole after being heated at high temperature punch forming, nothing
Extend to the crackle of matrix.
Second, Zn content is integrally higher than 30% in coating alloy phase, coating corrosion resistance is excellent.
