Description
Technical field
The utility model belongs to casting technology field, and in particular to a kind of interior crystallizer of hollow ingot casting device.
Background technology
Generally use protective gas cooling inside hollow ingot in the prior art, while play a part of air pressure balance, but protect
If the air pressure adjustment for protecting gas mismatches with casting speed can cause hollow ingot internal negative pressure, crystallization inwall is crushed, and
Manufacturing cost is higher.Existing interior crystallizer is cooled down using recirculated cooling water to hollow ingot, without secondary spray inside hollow ingot
Water cooling, ingot blank inside and outside inhomogeneous cooling is even, and ingot casting formability is poor, and certain fire check occurs inside ingot blank.
Utility model content
The purpose of this utility model is to provide a kind of interior crystallizer of hollow ingot casting device, to solve hollow ingot inside and outside
Air pressure imbalance can cause crystallization inwall to be crushed, and secondary cooling can not be carried out inside hollow ingot, cause ingot blank inside and outside cold
It is uneven, produce fire check the problem of.
In order to achieve the above object, the technical solution of the utility model is：
A kind of interior crystallizer of hollow ingot casting device, including fluid guide pad and the cooling water pipe of fluid guide pad bottom
Road, it is characterised in that：The periphery of the cooling water pipeline is provided with rigid support tube, is provided with the inside of the periphery of rigid support tube outer
Set, the inside of cooling water pipeline are provided with gas piping, and the bottom of interior crystallizer is provided with water spray flange.
In order to further realize the utility model, the angle between the water jet for flange of spraying water and the outer wall of gas piping is
15-45°。
In order to further realize the utility model, the axis of gas piping and the axis line overlap of interior crystallizer.
In order to further realize the utility model, overcoat is detachable.
In order to further realize the utility model, overcoat uses graphite, copper or copper alloy.
The utility model has the beneficial effect that compared to prior art：
The utility model design gas piping makes air be directly entered after plant for metal hollow ingot shaping in interior crystallizer, so as to
Hollow ingot inside and outside air pressure balance is kept, prevents from producing negative pressure inside hollow ingot, causes crystallization inwall to be crushed；Design spraying
Orchid can use the spray of different water spray angles as needed to reach the requirement that interior crystallizer secondary cooling water directly cools down
Water law is blue, and ingot blank inner surface secondary cooling intensity is adjusted, so as to improve hollow ingot inner surface cooling effect, makes crystallization group
Knit more uniform and stable, improve the castability of hollow ingot；Interior crystallizer uses split-type structural, and jacket internal has support to tie
Structure, proof strength, and overcoat is detachable, can be changed when crystallizer overcoat wears, and it is cost-effective.

The axis of gas piping 4 and the axis line overlap of interior crystallizer, the bottom of interior crystallizer are provided with water spray flange 5, water spray flange 5
Angle between the outer wall of water jet and gas piping 4 is 15-45 °.
During operation, molten metal is imported in annular cast cavity 7 by metal shunt 6, opens interior crystallizer cooling water
In cooling water pipeline 1 water is set once to be cooled down to the inner surface of ingot casting by overcoat 3.Treat plant for metal hollow ingot coagulation forming
Afterwards, dummy ingot structure is opened, plant for metal hollow ingot of slowly being left behind between interior crystallizer 8 and outer crystallizer 9, air is by gas piping 4
Top enter in hollow ingot, ensure hollow ingot inside and outside air pressure balance, 1 water is right by flange 5 of spraying water in cooling water pipeline
The inner surface of ingot casting carries out secondary cooling.
It can directly remove and be changed when the overcoat 3 of interior crystallizer wears.
