Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, the present invention provides a kind of technical solution：One kind can efficiently blowing argon gas and have the function of removal wadding flow
Stopper, including silk block 1, funnel conduit 2, stick body 3, inner cavity 4, through-hole awl 5, caput 6 and ventilative material 7, silk block 1 be mounted on interior
On the side wall of chamber 4, and inner cavity 4 is arranged in the inside of stick body 3, and funnel conduit 2 is fixed in inner cavity 4, the bottom of funnel conduit 2
Portion and the top of through-hole awl 5 are connected with each other, and through-hole awl 5 is mounted in caput 6, and caput 6 is arranged at the bottom of stick body 3
End, ventilative material 7 are arranged in the inside of caput 6, and the bottom end of ventilative material 7 and through-hole awl 5 is connected with each other.
The top of funnel conduit 2 is 100 millimeters at a distance from silk block 1 in this example, and silk block 1 is right on the side wall of inner cavity 4
Title is distributed with 2, and above-mentioned structure design allows funnel conduit 2 to play argon gas and 3 buffer action of stick body；
Through-hole awl 5 is divided to for two parts of concave head and plush copper, and the bottom of the concave head part and funnel conduit 2 of through-hole awl 5
End is connected with each other, and it is defeated that this structure design of through-hole awl 5 allows the argon gas transmitted by funnel conduit 2 to be concentrated
It is sent into ventilative material 7；
It is longitudinal for symmetry axis with 6 center of caput centered on the center of circle of circle where 6 center of caput, it is stick within the scope of 5 ° -30 °
The region for the ventilative material 7 filled in first 6, above-mentioned structure design enable ventilative material 7 to play the role of stable argon flow amount；
The material of ventilative material 7 is organized by weight as magnesium aluminate spinel 60%-80%, graphite 6%-20%, sawdust 5%-
15%, calcined alumina A powder 1%-2%, additive 1%-5%, bonding agent 5%-15%, and the group of additive is divided into metallic silicon
Powder, and bonding agent is thermosetting phenolic resin and liquid resin, and wherein phenolic resin carbon yield is more than or equal to 40%, solid content
More than or equal to 60%, above-mentioned 7 component of ventilative material makes ventilative material 7 that can not only ensure suitable apparent porosity, and can
It is resistant to enough temperature；
The top of ventilative material 7 is nested in the bottom end of through-hole awl 5, and the shape for facing section of ventilative material 7 is sector, on
The structure design stated makes through-hole awl 5 and ventilative material 7 are used cooperatively can ensure the continual and steady discharge of argon gas.
Operation principle：When using the present apparatus, the top of external tunger tube and stick body 3 is connected with each other, argon gas passes through outer
Portion's tunger tube enters in the inner cavity 4 being arranged in stick body 3, and by being arranged positioned at 2 bottom end of funnel conduit of 1 100 millimeters of lower section of silk block
Go out, is delivered into ventilative material 7 into through-hole awl 5, then by the plush copper structure of 5 bottom end of through-hole awl, argon gas is finally from stick
First 6 discharges stablized, this structure design so that removing wadding stream effect of the argon gas in inner cavity 4 and caput 6 is more efficiently thorough
Bottom, while device is whole when by 7 blowout argon gas of ventilative material, can not be made the argon gas of blowout by argon pressure influence of change
It is uniform and stable so that liquid level fluctuation of crystallizer will not be caused by the argon gas of ventilative material 7, cause liquid level slag, influence strand matter
Amount enables in entire casting process mold liquid level steadily without fluctuation, and funnel conduit 2 keeps apart argon gas with stick body 3, is ensuring
On the basis of argon pressure is stablized, the lower argon gas of temperature can also be directly isolated at severe cold winter, not connect with stick body 3
