Description
Technical field
The present invention relates to a kind of continuous casting system of metal, and in particular to a kind of to be capable of achieving to close the mother of amorphous alloy
Golden ingot casting carries out the system of continuously casting and the application method of the system.
Background technology
Amorphous alloy（Amorphous Alloy）All it is the alloy system of multicomponent as crystal alloy, but with
The periodic arrangement of atom is different in crystal alloy, in amorphous alloy, the characteristics of the arrangement of atom does not have long-range order,
Only in the vicinity of single atom with a certain degree of shortrange order.It is non-due to the special microstructure characteristic of amorphous alloy
Crystal alloy does not have the defects such as crystal boundary, dislocation and the twin of conventional crystal material, therefore with many excellent performances, it is such as unique
Electromagnetic performance, mechanical performance, high intensity hardness and high-corrosion resistance.So far, amorphous alloy（Abbreviation amorphous is closed
Gold）Research turned into one of very important research direction of current metal new material research and development.
The preparation method of non-crystaline amorphous metal is similar with conventional alloys, is all that will be made mother alloy ingot after raw material melting, then
Other deep processings are carried out again.The processing step for preparing amorphous master alloy ingot casting in the prior art is：First by the original of non-crystaline amorphous metal
Material is smelted into melt, during melt then delivered into set mould, the amorphous master alloy casting in mould is taken out after mould cooling
Ingot, the continuation that then repeats the above steps produces non-crystaline amorphous metal ingot；If obtaining the non-crystaline amorphous metal ingot of different size or shape,
Needing the amorphous master alloy ingot casting for changing mould or continuing to tentatively obtaining carries out the Physical Processings such as shaping, cutting.Existing
, it is necessary to expend the substantial amounts of artificial dismounting assembling for carrying out mould in the amorphous master alloy ingot casting preparation process of technology, cause production
Efficiency is low and the production time is long, especially when needing using different moulds, further increases the expense of mould so that manufacturing cost
It is high.To solve the above problems, many researchers consider to carry out the system of amorphous master alloy ingot casting using the mode of continuous casting
It is standby, in many researchs, will be applied in the continuous forming process of amorphous master alloy ingot for the continuous casting system made steel, but amorphous
Material is different from common ferrous materials, and non-crystalline material is oxidizable, using easy when making steel used continuous casting installation for casting or system
Amorphous master alloy ingot surface is caused to aoxidize.Also there are the continuous casting system for amorphous alloy material exploitation, such as Application No.
200910011405.4 is entitled《A kind of apparatus and method of continuous block metal glass shaping》Chinese invention patent in provide
A kind of have two continuous casting systems of the vacuum chamber that there is draught head, for realizing the continuously shaped of bulk metallic glass.On
Although the scheme of stating can be realized avoiding amorphous master alloy ingot surface from aoxidizing, but system two vacuum chambers of needs could be used,
And from for vacuum control operation above, its controllability is poor, and cost and operating cost are all high, should not promote the use of.
The content of the invention
Because non-crystaline amorphous metal surface easily aoxidizes under the high temperature conditions, so the continuous casting system for commonly using in the prior art
System is not fully suitable for the production process of non-crystaline amorphous metal.For this problem, many improvement projects are arisen at the historic moment, such as will be all
Non-crystaline amorphous metal production environment is set to vacuum completely, or non-crystaline amorphous metal is produced each step and is set to multiple vacuum environments by distribution,
Although logically there is the possibility realized, but for actual production, production cost and control condition are all in these schemes
Excessively high request, industrialized possibility is very low.The invention provides a kind of continuous casting of the amorphous alloy material of single vacuum chamber
System, amorphous alloy material surface aoxidizes in being not only prevented effectively from casting process, while the system architecture is simple, cost
It is cheap, it is adapted to large-scale use.
The technical problems to be solved by the invention are achieved by the following technical programs：
