Description
Technical field
The invention belongs to aluminium alloys to produce gas shield technical field, and in particular to a kind of gas for aluminium lithium alloy production
Body protective device.
Background technology
In aluminium lithium alloy production process, the particularly workshop sections such as injection forming, heat treatment, in order to prevent air intrusion causes
One of the oxidation of aluminium, the measure being usually taken are exactly to discharge inert gas by high temperature aluminium lithium alloy institute using gas shield device
In region and air insulated.
At present, protective gas is directly generally passed through by high temperature aluminium lithium alloy Processing Room using single protective gas pipeline, used
Protective gas displaces the oxygen in Processing Room, while holding Processing Room is needed to be in higher positive pressure always after the completion of displacement
State, there are following defects for such gas shielding condition：Processing Room space is larger, and protective gas leaks under higher barotropic state
Amount is big, while also there are the time needed for protective gas displaced air is long, displacement is not thorough, replaces the protective gas dosage of consumption
Greatly, the problems such as high so as to cause the production cost of low production efficiency, enterprise, halfway can seriously affect aluminium in the case that replacing
The quality of lithium alloy finished product.
Invention content
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of gas for aluminium lithium alloy production is provided
Protective device.
A kind of gas shield device for aluminium lithium alloy production, including：Gas interlayer, nozzle, it is characterised in that：It is described
The shape in the gas interlayer shape in section and Processing Room section in the horizontal direction in the horizontal direction is identical, and gas interlayer passes through partition board
If being divided into dried layer air compartment, the both ends of several nozzles are respectively with air compartment and communicating Processing Room and communicating, the center line and circle of nozzle
Cylindricality aluminium lithium alloy workpiece wall surface is tangent, one end phase that the both ends of every layer of air compartment pass through every layer of protective gas branch pipe and every layer of manifold
Logical, the other end of every layer of manifold is communicated with protective gas storage tank.
Preferably, flame retardant coating, gas interlayer and Processing Room can be equipped with or are not provided between the gas interlayer and Processing Room
Between can be equipped with or be not provided with water leg layer.
Preferably, it is mounted on intake valve on every layer of manifold.
Preferably, 20~40m/s of protective gas flow velocity in the nozzle.
Preferably, what is stored in the protective gas storage tank is argon gas or nitrogen.
Compared with prior art, beneficial effects of the present invention：
The present invention sprays into the protective gas of certain rigidity by the tangent nozzle of several groups of center lines and aluminium lithium alloy workpiece,
So that the air-flow of rotation is formed around aluminium lithium alloy workpiece, it is ensured that low oxygen content atmosphere is in around aluminium lithium alloy workpiece always,
It avoids the oxidation of high temperature aluminium lithium alloy workpiece, while the protective gas amount that each layer air compartment be passed through is adjusted by intake valve, reduce and protect
Gas usage is protected, saves enterprise's production cost.
