Description
Technical field
The present invention relates to a kind of aluminum magnesium alloy explosion-proof lamp, especially relate to a kind of rare-earth-Al-Mg alloy block blast-proof materials.
Background technology
Instantly, oil, methane etc. are flammable or inflammable substance have become human indispensable chemical energy source, yet the transportation of these resources or storage have but increased the danger that causes fire and blast.Show that according to pertinent data because of fire or the blast big fire of initiation afterwards flammable or that inflammable substance cause, in a single day more difficult control of more common fire fire alarm or blast takes place usually, fire-fighting can only be done aftermath, in the hope of reduce the loss as far as possible.
To the problems referred to above, over nearly 20 years, research staff both domestic and external successively specializes in explosion-proof, the explosion-suppressing material that are used for flammable or inflammable substance, and has obtained some achievements.The explosion-suppressing material that is used for combustible and explosive articles (Chinese patent publication number 1077172, its disclosed material composition is: Mn0.8～1.8, Fe0.3～0.7, Si0.3～0.6, Cu0.1～0.2, Zn0.1, Mg0.03～0.1, surplus are Al) like No.52 Inst., Ministry of Chinese Weapons Industry's research and development is just processed by the extraordinary alloy foil net after joint-cutting and the expansion.This material is divided into netted and spherical two kinds of explosion-suppressing materials, has cellular vesicular structure.If using this material fills the volatile inflammable liquid storage vessel; If fill proper; Even when having reached high-explosive condition in the storage vessel; Also can brisance (pressure of explosion peak value) be reduced, container is interior by behind effective datonation-inhibition requirement filling lightweight explosion-suppressing material simultaneously, and container net volume rate of loss is merely 1.2～1.4%.It intercepts explosion-proof principle: because the mesh in the explosion-suppressing material lamination has cellular vesicular structure, can be divided into many very little " compartments " to the fuel tank inner chamber.These " compartments " can be contained flame transmission, simultaneously, utilize the heat-conduction effect of its material, can promptly burning be discharged the most heat absorption in ground and fall.Outlet temperature Tf after the combustion reactions is reduced greatly, and the degrees of expansion of reactant gases is dwindled, and the force value of container increases not quite.
But so far, such aluminum magnesium alloy explosion-suppressing material is not at home and abroad promoted the use of preferably.Its reason is: existing aluminum magnesium alloy intensity, unit elongation performance are limited, the fragment that is easy to generate in the use so that stop up oil circuit.And because the explosion-proof lamp long period of soaking in the inflammable and explosive substances medium, causes the hydronalium corrosion easily.In addition, in the high temperature and high pressure environment of material when firing, it is desirable not enough with strength property that it is high temperature resistant, heat resistanceheat resistant is split.Exactly because existing aluminum magnesium alloy explosion-suppressing material exists a lot of deficiencies, causes its range of application not extensive.
Summary of the invention
The purpose of this invention is to provide a kind of rare-earth-Al-Mg alloy block blast-proof materials, not corrosion-resistant to solve existing aluminum magnesium alloy explosion-proof lamp, intensity, unit elongation, high temperature resistant, technical problem that heat crack resistance is limited.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of rare-earth-Al-Mg alloy block blast-proof materials, and it is processed by following chemical components by mass percentage: Mg0.8～1.8%, Fe0.3～0.5%; Si0.3～0.6%; Mn0.8～1.8, Cu0.1～0.2%, Zn0.1～0.2%; Rare earth metal 0.45～1.0%, surplus are aluminium and unavoidable impurities.
As preferably, in component of the present invention: the concrete component of rare earth metal is: Y, Ce, La, Sc; Wherein each element accounts for the per-cent of material total mass and is: Y0.1～0.2%, Ce0.1～0.2%, La0.2～0.5%, Sc0.05～0.1%.
Rare earth metal has reinforcement, rotten, Water purification in the aluminum magnesium alloy explosion-proof lamp, can reduce the solidus curve of alloy, dwindles hot vulnerable areas effectively.In the aluminum magnesium alloy liquation, add 0.45～1.0wt% rare earth metal, can absorb wherein a part of hydrogen, thereby can obviously reduce the pin hole that causes because of the hydrogen of separating out in the aluminum magnesium alloy process of setting.The aluminum magnesium alloy oxidation under 600～760 ℃ of temperature that stops.Adding rare earth metal also can make microalloies such as FeAl in the aluminum magnesium alloy, AlFeSi equate to form the polybasic metallic compound; Make iron phase refinement and even nodularization thick in the aluminum magnesium alloy; Make silicon change into fine strip shape and particulate state, thereby significantly improved the mechanical property of aluminum magnesium alloy explosion-proof lamp by thick sheet.
Specifically, in the rare earth metal that will add required for the present invention, La (lanthanum) is the most obvious to removing nonmetallic impurity such as oxygen, sulphur, phosphorus and low melting point metal impurity effects such as lead, tin, and can also crystal grain thinning.Generation LaAl, La intermetallic compounds such as (CuAl) play a part to strengthen crystal boundary, thereby have reduced hot cracking tendency.
Y (yttrium) has good anti-decaying spheroidisation effect, is good scavenging agent and the property-modifying additive in the aluminum magnesium alloy explosion-proof lamp, and the aluminum magnesium alloy explosion-proof lamp that adds yttrium has the good high-temperature antioxidant property.
Many elements in Ce (cerium) and the aluminum magnesium alloy form intermetallic compounds such as AlCuCe, AlSiCe, and intermetallic compound is at high temperature very stable, and hardness is high and be net distribution in crystal boundary, can hinder the creep slippage, thereby play the effect of High-Temperature Strengthening.Make the intensity and the hardness of alloy improve, and can when the fuel explosive combustion, reduce the hot tearing that the aluminum magnesium alloy explosion-proof lamp produces, the resistance to elevated temperatures of aluminum magnesium alloy explosion-proof lamp is further improved.Sc (scandium) comes compared with yttrium and lanthanum element, though consumption is less, effect obviously.The scandium of very small amount adds in the aluminum magnesium alloy explosion-proof lamp, just can further improve intensity and the resistance toheat of aluminum magnesium alloy explosion-proof lamp in high temperature, high pressure extreme environment.
The present invention through after rare-earth metal modified, makes the aluminum magnesium alloy explosion-proof lamp have the intensity height to aluminum magnesium alloy through chemical ingredients is reasonably designed, good toughness, and corrosion-resistant, plurality of advantages such as ability is strong are split in heat resistanceheat resistant.After in fuel tank, placing this aluminum magnesium alloy explosion-suppressing material; When running into naked light, static, bump, thunderbolt and accident and clash accident; Can intercept flame burning, slow down the speed of propagation of flame, obviously reduce the flame height; Prevent the container accident of blasting, therefore have good explosion-proof, datonation-inhibition function.This material has the anodic protection function simultaneously, prevents the corrosion of container inner wall, prolongs the container life-span.Can be widely used in the fuel transport car, fuel tank such as the fuel truck that flows, aircraft gas refueller, military vehicle, aircraft, naval vessels or oil tank explosion-proof.Also can be used for the explosion-proof of inflammable and explosive containers such as various storage gasoline, diesel oil, oil of bananas, acetone.
