The shielding gas with certain rigidity is sprayed through the nozzles, and the center lines of the nozzles are tangent to the aluminum lithium alloy workpiece, so that a rotating air flow is formed around the aluminum lithium alloy workpiece, the periphery of the aluminum lithium alloy workpiece is enabled to be at a low oxygen content atmosphere all the time, the oxidation of the aluminum lithium alloy workpiece at high temperature is avoided, the use amount of the shielding gas is reduced, and the production cost of the enterprise is reduced.
Description
Technical field
The invention belongs to aluminium alloy production gas shield technical field, and in particular to a kind of gas for aluminium lithium alloy production
Body protection device.
Background technology
In aluminium lithium alloy production process, the particularly workshop section such as reaction-injection moulding, heat treatment causes to prevent air from invading
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, typically protective gas is directly passed through by high temperature aluminium lithium alloy Processing Room using single protective gas pipeline, is used
Protective gas displaces the oxygen in Processing Room, while needing to keep Processing Room to be in higher malleation all the time after the completion of displacement
There is following defect in state, this kind of gas shielding condition：Processing Room space is larger, protective gas leakage under higher barotropic state
Amount is big, while also there is the time length needed for protective gas displaced air, displacement is thorough, replace the protective gas consumption for consuming
Greatly, so as to cause the production cost of low production efficiency, enterprise high the problems such as, aluminium can be had a strong impact in the case of displacement is halfway
The quality of lithium alloy finished product.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of gas for aluminium lithium alloy production
Protection 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 dividing plate
If being divided into dried layer air compartment, the two ends of several nozzles respectively with air compartment and communicate Processing Room and communicate, the center line and circle of nozzle
Cylindricality aluminium lithium alloy workpiece wall is tangent, one end phase that the two ends of every layer of air compartment pass through every layer of protective gas arm and every layer of house steward
Logical, the other end of every layer of house steward is communicated with protective gas storage tank.
Preferably, flame retardant coating, gas interlayer and Processing Room can be provided with or are not provided between the gas interlayer and Processing Room
Between can be provided with or be not provided with water leg layer.
Preferably, it is mounted on intake valve on every layer of house steward.
Preferably, protective gas 20～40m/s of 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 some groups of center lines and aluminium lithium alloy workpiece,
So that forming the air-flow of rotation around aluminium lithium alloy workpiece, it is ensured that be in low oxygen content atmosphere around aluminium lithium alloy workpiece all the time,
The oxidation of high temperature aluminium lithium alloy workpiece is avoided, while adjusting the shielding gas scale of construction that each layer air compartment is passed through by intake valve, reduces protecting
Shield gas usage, saves enterprise's production capacity.
