Description
Technical field
The invention belongs to metal alloy compositions fields, and in particular to a kind of Heat-insulation metal material.
Background technique
Heat insulating metal is to meet a kind of New Building Materials of building energy conservation requirement, it is the nonmetallic materials with lower thermal conductivity
Connecting has composite material heat-insulated, every cold function made of alloy architectural shape.It is had in addition to having as architectural shape
Outside some characteristics, also there is excellent thermal insulation property and sound insulation property.
The principle of heat insulating metal be in a metal between penetrate heat insulating strip, there are mainly two types of the production methods of heat insulation section, one
Kind be that the processes such as item, rolling formation " insulation bridge " by mechanical tooth punching, is worn using heat-insulated strip material and metal material, referred to as every
Hot profiles " penetrating bar type "；Another kind is heat-barrier material to be poured into the heat-insulation chamber body of metal material, by solidification, removes bridge cut-off
The processes such as metal form " insulation bridge ", referred to as " cast-type " heat insulation section.The inside and outside two sides of heat insulation section, can be different section
Profile, be also possible to the different colours profile of different surface treatment mode.But by region, the influence of weather is avoided because heat-insulated
Having a long way to go for the linear expansion coefficient of material and metal material, larger stress and gap are generated therebetween when expanding with heat and contract with cold；
Heat-barrier material and metal material are combined into one simultaneously, the same stress.It is therefore desirable to which heat-barrier material must also have and metallochrome material
Expect tensile strength, the bending strength being close, the coefficient of expansion and elasticity modulus, otherwise insulation bridge will be made to be disconnected and be broken
It is bad.Therefore, the selection of heat-barrier material is very important.
Magnesium alloy can be divided into cast magnesium alloy and wrought magnesium alloy by forming technology, and the two is deposited in ingredient, structure property
In very big difference.Cast magnesium alloy is mainly used for auto parts, parts clamshell and electric member etc.；Wrought magnesium alloy is mainly used for
Thin plate, extrusion and forging etc..Cast magnesium alloy has the property that：Crystallization temperature interval is big, and body is shunk and linear shrinkage is big, group
The eutectic scale of construction, specific heat capacity, latent heat of solidification, density and liquid head in knitting is small, and mobility is low, drawing crack, shrinkage porosite tendency one
As it is much bigger compared with cast aluminium alloy gold.
It is very strong with the affinity of oxygen since the chemical property of magnesium is active during magnesium alloy smelting, and in smelting temperature
Having very high vapour pressure down, (700 DEG C, the vapour pressure of magnesium is 875Pa, and aluminium is 4.19 × 10-6Pa), it is easy in air
Oxygen reacts.Therefore, during magnesium alloy smelting, it is necessary to take necessary safeguard measure.There are mainly two types of protect at present
Shield measure：Cover saline flux and covering reactant gas.Covering salt solvent is by covering the halogen mixture of low melting point
It covers in bath surface, is melted into liquid at a lower temperature, spread out in alloy liquid level, prevent contact of the magnesium with air, thus
Pure magnesium and magnesium alloy not oxidizing fire are protected, still, protecting flux is generally made of villaumite and villiaumite, can be produced in use
Salt steam (such as HCl, Cl of raw a large amount of irritant smells2) and flux be mingled with, ambient enviroment and alloy mechanical property are made
At destruction.Simultaneously because the density of flux is bigger gradually to sink, need constantly to add.A large amount of nocuousness are released in use process
Gas, pollution environment, corrosion workshop are serious.Therefore, study that novel covering, refining effect be good and non-harmful magnesium alloy flux
It is an important topic.Covering reactant gas method is to cover one layer on the surface of liquid magnesium alloy to react the fine and close oxygen of generation with magnesium
The gas for changing film, thus the oxygen in air-isolation.Currently used protective gas is neutral gas or SO2, but work as SO2From atmosphere
When middle disappearance, which will rupture, and Serum Magnesium burns.Meanwhile SO2Gas itself has stronger corrosivity and thorn
Swash property, safety hazard is brought to smelting equipment and operator.If using N simultaneously2Words react with magnesium and generate Mg3N2, should
Film is loose porous, and reaction cannot be prevented to continue, and when agitation, can be mixed into, and forms non-metallic inclusion.Therefore, it is necessary to seek
Look for more environmentally protective, protective method for smelting of magnesium alloy easy to operate.
