Abstract
This utility model relates to a kind of rotor, particularly discloses a kind of graphite rotator preventing aluminium alloy from aoxidizing.It includes graphite bars and graphite impeller, it is characterized in that, described graphite bars and graphite impeller are the hollow structures communicated, and described graphite impeller is provided with venthole；Described graphite bars upper end connects getter by connection dish；Graphite covering dish it is cased with in described graphite bars.Between described graphite bars and graphite impeller threaded.This utility model is in the middle of high cleanliness aluminum base or in the preparation process of other alloys, not only can reach extraordinary mixing effect, it is also prevented from being involved in of secondary oxidation slag inclusion of aluminium alloy, and carry out refine degassing processing, not only substantially increase the quality preparing alloy, also shorten technological process, improve work efficiency.
Description
(1) technical field
This utility model relates to a kind of rotor, particularly to a kind of graphite rotator preventing aluminium alloy from aoxidizing.
(2) background technology
In recent years, along with the fast development of domestic aluminum processing industry, the domestic supply and demand to contained aluminium-base intermediate alloy increased every year
Rate all surpasses 20%, is brisk for supply and demand, and China's contained aluminium-base intermediate alloy market development is good.It is limited to the most domestic equipment,
The contained aluminium-base intermediate alloy preparing high cleanliness also lacks means, particularly the degasification stirring to aluminium alloy always.The most common stir
Although mixing rotor can reach mixing effect, but whipping process can not prevent the volume of the secondary oxidation slag inclusion of aluminium alloy
Entering, and easily cause the great increase of hydrogen content in whipping process, this both increases the difficulty of subsequent treatment.
(3) summary of the invention
This utility model is in order to make up the defect of prior art, it is provided that a kind of graphite preventing aluminium alloy from aoxidizing turns
Son.
This utility model is achieved by the following technical solution:
A kind of graphite rotator preventing aluminium alloy from aoxidizing, including graphite bars and graphite impeller, is characterized in that, described graphite
Bar and graphite impeller are the hollow structures communicated, and described graphite impeller is provided with venthole；Described graphite bars upper end is by connection dish
Connect getter；Graphite covering dish it is cased with in described graphite bars.
Between described graphite bars and graphite impeller threaded.
The beneficial effects of the utility model are:
This utility model, in the middle of high cleanliness aluminum base or in the preparation process of other alloys, not only can reach extraordinary
Mixing effect, it is also possible to prevent being involved in of secondary oxidation slag inclusion of aluminium alloy, and carry out refine degassing processing, be not only greatly improved
Prepare the quality of alloy, also shorten technological process, improve work efficiency.
(4) accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described:
Fig. 1 is the sectional structure schematic diagram during this utility model uses.
In figure, 1 graphite bars, 2 graphite impeller, 3 getters, 4 ventholes, 5 graphite covering dishes, 6 crucibles, 7 connection dishes, 80,000
To connector interface.
(5) detailed description of the invention
Accompanying drawing is specific embodiment of the utility model.Being illustrated in figure 1, the graphite that this kind can prevent aluminium alloy from aoxidizing turns
Son, including graphite bars 1 and graphite impeller 2, the top of graphite bars 1 connects getter 3, graphite bars 1 and graphite leaf by connection dish 7
Wheel 2 is all hollow structure, and is connected between getter 3, graphite bars 1 and graphite impeller 2, and graphite impeller 2 is provided with gives vent to anger
Hole 4；Being cased with graphite covering dish 5 in graphite bars 1, the diameter of graphite covering dish 5 is slightly less than the internal diameter of crucible 6, declines in graphite bars 1
After in aluminium alloy, covering dish swims in above aluminium alloy, has isolated contacting of aluminium alloy and air in whipping process, thus has reached
To anti-oxidation effect.Between graphite bars 1 and graphite impeller 2 threaded, this threaded must assure that stirring time stone
Ink impeller 2 is tightly rather than more and more loose in graphite bars 1.
In work process, argon or nitrogen in getter 3 are passed through in graphite bars 1 by universal joint interface 8, then warp
Venthole 4 in graphite impeller 2 is passed through in aluminium alloy, makes aluminium alloy be purified, noble gas during high speed rotating stirs
Being broken into substantial amounts of disperse bubble, and make it be dispersed in aluminium alloy, bubble is inhaled by partial pressure difference and surface in aluminium alloy
Attached principle, absorbs the hydrogen in aluminium alloy, adsorption and oxidation slag inclusion, and rises with bubble and be carried over aluminium alloy surface, graphite simultaneously
Floating heavy being pressed on aluminium alloy of covering dish 5 completely cuts off oxidizing gas, makes aluminium alloy carry out melting in closing space, prevents from stirring shape
The alloy whirlpool become is involved in Slag inclusion, reaches anti-oxidation effect, thus prepares the aluminium intermediate alloy of high cleanliness.
In addition to technical characteristic described in description, remaining technical characteristic is all known to a person skilled in the art technology.
Claims (2)
1. can prevent the graphite rotator that aluminium alloy aoxidizes, including graphite bars (1) and graphite impeller (2), it is characterized in that, described
