Abstract
The utility model discloses a kind of gas shield device produced for aluminium lithium alloy, including：Gas interlayer, nozzle, it is characterised in that：The shape in the gas interlayer shape in section and Processing Room section in the horizontal direction in the horizontal direction is identical; if gas interlayer is divided into dried layer air compartment by dividing plate; the two ends of several nozzles are respectively with air compartment and communicating Processing Room and communicating; the center line of nozzle and cylindrical aluminium lithium alloy workpiece wall are tangent; the two ends of every layer of air compartment are communicated by every layer of protective gas branch pipe with one end of every layer of house steward, and the other end of every layer of house steward is communicated with protective gas storage tank.The utility model 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; ensure to be in low oxygen content atmosphere around aluminium lithium alloy workpiece all the time; avoid the oxidation of high temperature aluminium lithium alloy workpiece; protective gas consumption is reduced, enterprise's production cost is saved.
Description
Technical field
The utility model belongs to aluminium alloy production gas shield technical field, and in particular to one kind is used for aluminium lithium alloy production
Gas shield device.
Background technology
In aluminium lithium alloy production process, the workshop sections such as shaping, heat treatment are particularly sprayed, in order to prevent air intrusion from causing
The oxidation of aluminium, one of the measure being usually taken is 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 typically 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 needing to keep Processing Room to be in higher malleation all the time after the completion of displacement
There is following defect in state, such a gas shielding condition：Processing Room space is larger, and protective gas is leaked under higher barotropic state
Amount is big, while the time length, displacement needed for also there is protective gas displaced air is not thorough, displacement consumption protective gas consumption
Greatly, so as to cause the problems such as production cost of low production efficiency, enterprise is high, aluminium can be had a strong impact in the case of displacement is halfway
The quality of lithium alloy finished product.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art to be used for what aluminium lithium alloy was produced there is provided a kind of
Gas shield device.
A kind of gas shield device produced for aluminium lithium alloy, 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 are respectively with air compartment and communicating Processing Room and communicating, the center line and circle of nozzle
Cylindricality aluminium lithium alloy workpiece wall is tangent, and the two ends of every layer of air compartment pass through every layer of protective gas branch pipe and one end phase of every layer of house steward
Logical, the other end of every layer of house steward is communicated with protective gas storage tank.
Preferably, it can be provided with or be not provided with flame retardant coating, gas interlayer and Processing Room 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, 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, the beneficial effects of the utility model：
The utility model sprays into the protection of certain rigidity by the tangent nozzle of some groups of center lines and aluminium lithium alloy workpiece
Gas so that the air-flow of rotation is formed around aluminium lithium alloy workpiece, it is ensured that be in low oxygen content around aluminium lithium alloy workpiece all the time
Atmosphere, it is to avoid the oxidation of high temperature aluminium lithium alloy workpiece, while adjusting the protective gas amount that each layer air compartment is passed through by intake valve, drops
Minimum living protects gas usage, saves enterprise's production cost.
