Background technology
At present both at home and abroad with the demand of the fast development of modern industry, especially space flight and aviation military technology, to machinery
Parts material requirements also more and more higher, all the more harsh to the indices performance of metal material, ordinary metallurgical technology can not expire
Sufficient demand.Extraordinary metallurgical technology is constantly had an optimistic view of by people, such as vacuum metling, vacuum arc remelting, vacuum double refining etc..
The advantages of vacuum metallurgy is the furnace gas for not making material contamination, prevents gaseous metal from reoxidizing, particularly living to containing aluminium, magnesium etc.
Vacuum induction melting technique must be used by sprinkling the alloy of the more element of element.So vacuum metallurgy skill of domestic and international diversified forms
Art is continued to develop, and if patent of invention number is a kind of medium-frequency induction furnaces of ZL2013.10449993.6, it has the beneficial effect that
A kind of medium-frequency induction furnace, can realize and vacuumize, and can realizes Bottom Argon Stirring.Bottom tapping can be realized simultaneously, but
Bottom tapping technique also Shortcomings, need to improve.
The content of the invention
It is a kind of with the bottom tapping running gate system vacuumized it is an object of the invention to provide regarding to the issue above, with solution
Room air is cast in certainly existing bottom tapping to cause to pour into a mould reoxidizing for product.
The purpose of the present invention is to be achieved through the following technical solutions：
It is a kind of with the bottom tapping running gate system vacuumized, including furnace lining, bottom fistulae, cast switch, sluice way, mold
Room, cooling inlet/outlet pipe, vacuum connection tube, vavuum pump.
Further, described furnace lining is the container of smelting metal, and furnace lining bottom connects bottom fistulae.
Further, described bottom fistulae can be made of exotic material, and cast switch connection, at connection cast switch
Also can be separated with thermal resistance part.
Further, described cast switch is made from suitable exotic material, and the mode of Push And Release can be according to work
Skill demand is set, cast switch lower section connection sluice way, if any sluice way can be also made of exotic material, also can directly be connected
It is connected to mold room.
Further, described sluice way is set according to pouring technology, if desired for when according to technological requirement set make
Molten steel is oriented to drainage, and sluice way is more short better in principle, upper end connection cast switch, lower end connection mold room.
Further, described mold room is for molten steel cooling and shaping product.
Further, described cooling inlet/outlet pipe be to improve production efficiency, for quickly cooling down the interface of mold room,
Can continuously or semi-continuously circulating cooling according to process requirements.
Further, described vacuum connection tube, an end is connected on mold room, another to terminate at vavuum pump, if necessary vacuum
Connecting tube can cooling treatment.
Further, described vavuum pump should be started before molten steel is poured into a mould and vacuumized.Ensure sluice way and mold before pouring into a mould
Room is under vacuum conditions.
Further, it is described a kind of with the bottom tapping running gate system vacuumized, it is characterised in that bottom fistulae is vertical
Furnace lining bottom is connected to, also can be tiltedly connected to according to demand above furnace lining bottom, be attached on vacuum high-frequency induction furnace, also may be used
Any smelting furnace substrate portion is connected to, is particularly suitable for being connected on vacuum medium frequency induction furnace, makes the product of cast cleaner,
Better quality.
Beneficial effects of the present invention are good, described a kind of with the bottom tapping running gate system vacuumized.Due to bottom tapping
When, mold room has completely cut off air into vacuum, molten steel when flowing into mold room, it is therefore prevented that gaseous metal reoxidizes, and improves product
Clarity, metal reduction temperature and evaporating temperature are reduced, saves electric cost.The realization of the technique, international state is filled up
Interior blank, there are huge market prospects and the market competitiveness.
Brief description of the drawings
It is a kind of structural representation with the bottom tapping running gate system vacuumized of the present invention in figure.
In figure
1. furnace lining；2. bottom fistulae；3. cast switch；4. sluice way；5. mold room；6. cool down inlet/outlet pipe；7. bonding in vacuum
Pipe；8. vavuum pump
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
It refer to shown in Fig. 1, figure one is a kind of structural representation with the bottom tapping running gate system vacuumized of the present invention
Figure.In the present embodiment.It is a kind of to include furnace lining 1 with the bottom tapping running gate system vacuumized and set to be connected to furnace lining bottom
Bottom fistulae 2, cast switch 3, sluice way 4, mold room 5 and the cooling inlet/outlet pipe 6 and vacuum connection tube that are connected on mold room 5
7 and vavuum pump 8 on.
When the molten steel in furnace lining reaches pouring temperature, vavuum pump is started first, makes sluice way, the casting of cast switch lower section
Mould room keeps under vacuum conditions, opening cast switch connection lower channel, and molten steel passes through sluice way by switching channels, such as
Have, into mold room cooling and shaping.Pouring into a mould molten steel can continuously pour into a mould and be poured into a mould with gap according to Product Process, semicontinuous cast.
To improve production efficiency, mold room can cool down according to technological requirement, while carry out continuously or semi-continuously circulating cooling.According to technique
It is required that bottom fistulae can be vertically connected on furnace lining bottom surface and tiltedly be connected to above furnace lining bottom.Above pouring procedure does not have due to molten steel
By air pollution, it is therefore prevented that gaseous metal reoxidizes, and improves product clarity, reduces metal reduction temperature and evaporation temperature
Degree.Simultaneously because bottom tapping, can reduce pouring temperature, electric cost is saved.The realization of the technique, international and domestic sky is filled up
In vain, there are huge market prospects and the market competitiveness.
Above example is to elaborate the general principle and characteristic of the present invention, and the present invention is not limited by above-described embodiment,
Without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and modifications all fall
In the range of entering claimed invention, the claimed scope of the invention is by appended claim and equivalent thereof.
