Description
Technical field
The present invention relates to a kind of corrosion resistant datonation-inhibition packing material that is used in flammable and combustible liquids or the gas reservoir, belong to functional aluminum alloy materials.This material has excellent erosion resistance and high ductibility, is also keeping desirable HS simultaneously.
Background technology
The earlier application 92102437.1 of our company discloses a kind of explosion-suppressing material that is used for combustible and explosive articles, and a kind of suppress flammable fluid burning and the netted and spherical explosion-suppressing material that explodes in the container are provided.The chemical weight percent of this material is: Mn is 0.8～1.8, and Fe is 0.3～0.7, and Si is 0.3～0.6, and Cu is 0.1～0.2, and Zn is 0.1, and Mg is 0.03～0.1, and Al is a surplus.Netted explosion-suppressing material is by folded system of the aluminium foil after joint-cutting and the expansion or coiling moulding, and the grid between layer and the layer is staggered superimposed with equidirectional, and some grids form unordered cross structure each other, are the superimposed body of the several layers of honeycomb-like pore structure; Spherical explosion-suppressing material is processed by the aluminium foil after joint-cutting and the expansion, outer surface smoother, and inside is honeycomb-like pore structure.Discover that in practice this YIELD STRENGTH, tensile strength, elongation all await improving, fragility awaits reducing, and is prone to fragment in the use, can cause danger such as oil circuit obstruction; And in order to reduce the productive expense of extrusion molding, reduce extrusion molding pressure and all require good ductility with raising extrusion molding speed.
This shows that the aluminum alloy explosion suppression material of use must have high ductibility, excellent erosion resistance, and have the intensity that meets the requirements.
Summary of the invention
The object of the present invention is to provide a kind of aluminum alloy explosion suppression packing material that is used in flammable and combustible liquids or the gas reservoir, this material has excellent erosion resistance and high ductibility, is also keeping desirable HS simultaneously.According to the present invention, each alloy material in the explosion-suppressing material must exist with the amount of stipulating separately, and its reason is following:
Silicon Si improves the intensity of duraluminum through the precipitation hardening effect.When silicon existed, its strengthening effect was significant.But undue silicone content not only improves the liquidus temperature of alloy, is unfavorable for the melting and the casting of alloy, and reduces the plasticity of explosion-suppressing material.Therefore, bigger silicone content is undesirable, and in the present invention, silicone content should be controlled at 0.05～0.15% (weight).
Copper Cu solid solution strengthened alloy matrix phase can promote the intensity of material, so the content of copper is necessary for 0.3% (weight) or higher, still, and when copper content surpasses 0.7% (weight), erosion resistance that can the severe exacerbation alloy material.Therefore, the content with copper is controlled at 0.3～0.7% (weight).
Manganese Mn can stop the recrystallization process of duraluminum, improves recrystallization temperature, remarkable refinement recrystal grain, and pass through MnAl
6Dissolved impurity iron reduces the harmful effect of iron.Manganese matches with magnesium can improve the intensity of material, but undue manganese content, with the ductility that influences material, so manganese content is necessary for 0.8～1.1% (weight).
Magnesium Mg forms magnesium silicide chemical combination mutually with silicon, is deposited in and improves intensity in the alloy matrix aluminum.Therefore, Mg content must be greater than 0.8% (weight), and still, Mg content will further not provide precipitating action greater than 1.2% (weight).
The content of chromium Cr should be between 0.1～0.5% (weight), and the increase of chromium increases the erosion resistance of material, but sacrificed the part ductility of material, but the ductility that the chromium of above-mentioned scope makes material still within the acceptable range.And chromium cooperates with manganese can suppress grain coarsening, and for this reason, its content also should be greater than 0.3% (weight), and therefore, chromium content of the present invention is 0.1～0.5% (weight), preferred 0.3～0.5% (weight).
When the processing of explosion-suppressing material need be carried out hot rolling or low-temperature annealing; Add an amount of zirconium Zr and can make product produce recrystallization completely, thereby increase the intensity of material, but along with the formability of the increase material of zr element descends; Therefore, the content of zirconium should be less than 0.08% (weight).
Titanium Ti can make the crystal structure refinement, suppresses crackle and other generation of defects, adds the distortion in man-hour evenly; Excellent performance; Product intensity and elongation are higher, the content of titanium is controlled at 0.03～0.18% (weight) can also makes erosion resistance reach best, simultaneously; When titanium content is in 0.03～0.05% (weight) scope, can also guarantee the toughness of explosion-suppressing material.
Iron Fe is the inevitable impurity element that exists in the aluminum alloy materials, forms the Al-Fe-Si compound, is scattered in the alloy substrate with particle shape, causes undesirable negative impact of ductility and erosion resistance.Therefore, the content of iron should be low as much as possible, considers the difficulty of actually operating, and the upper limit of iron level should be no more than 0.2% (weight), preferably is controlled at 0.06～0.2% (weight).
The content of zinc Zn should maintain in 0.05～1% (weight) scope, and preferred 0.06～0.5% (weight) further is controlled in 0.1～0.2% (weight) scope.
The present invention provides a kind of aluminum alloy explosion suppression packing material that is used in flammable and combustible liquids or the gas reservoir, and this material has excellent erosion resistance and high ductibility, is also keeping desirable HS simultaneously; This material is netted or spherical, has the honeycomb hole gap structure, and its chemical ingredients is: Si 0.05～0.15% (weight); Cu 0.3～0.7% (weight), Mn 0.8～1.1% (weight), Mg 0.8～1.2% (weight); Cr0.1～0.5% (weight), preferred 0.3～0.5% (weight), Ti 0.03～0.18% (weight); Fe is less than 0.2% (weight), Zn 0.05～1% (weight), and surplus is Al.
In order further to increase the intensity of material, can also add Zr less than 0.08% (weight).
Explosion-suppressing material of the present invention has strengthened erosion resistance and ductility, is not prone to fragment, has avoided danger such as oil circuit obstruction.
