Abstract
The invention relates to a magnesium lithium alloy cast ingot anti-cratering thermal insulator which comprises a thermal insulation sleeve, wherein the inner cavity of the thermal insulation sleeve is in the shape of an inverted funnel, and both sides of the thermal insulation sleeve are provided with an adjusting yoke. The magnesium lithium alloy cast ingot anti-cratering thermal insulator is put on the upper port of the magnesium lithium alloy cast ingot mold, and the adjusting yoke is adjusted to extend to the depth of 20-50mm below the casting solution level; and due to the space and angle of the inner cavity, the casting solution level rises, and the risen part of the casting solution level partially departs from water cooling under the action of a thermal insulation layer, thereby reducing the cooling rate, enhancing the solution feeding capacity and further preventing the problem of cratering caused by quick cooling. The invention has the characteristics of simple structure, high processability, high production efficiency and high yield.
Description
Technical field
The present invention relates to a kind of attemperator, be specifically related to the anti-shrinkage cavity attemperator of a kind of magnesium lithium alloy ingot casting, be used for magnesium lithium alloy material melting casting cycle and prevent and solve the ingot casting shrinkage cavity and cross the dark problem of serious offense.
Background technology
Magnesium lithium alloy melting under vacuum; Ingot casting can cause alloy solution to cool off rapidly at the ingot mould wall in the hydronic process of water; Ingot mould is mobile poor, and feeding capacity is poor, excessive shrinkage cavity can occur at the ingot casting upper surface; Cause the major defect of magnesium lithium alloy ingot casting, make the ingot casting yield rate low low with production efficiency.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the object of the present invention is to provide a kind of magnesium lithium alloy ingot casting to prevent the shrinkage cavity attemperator, have simple in structure, be easy to process, production efficiency height and the high characteristics of yield rate.
To achieve these goals, the technical scheme that the present invention adopts is: a kind of magnesium lithium alloy ingot casting is prevented the shrinkage cavity attemperator, includes an inner chamber and is upside down funnel shape insulation sleeve, and the both sides of insulation sleeve are provided with the adjusting support.
The lower inner cavity wall of described insulation sleeve and the angle a between the last internal chamber wall are 10 °～20 °.
Described insulation sleeve extend into the degree of depth of 20～50mm below the casting liquid level.
Described insulation sleeve adopts the high temperature stainless steel material to process.
Be provided with the exhausted pad insulating layer of asbestos in the housing of described insulation sleeve.
The upper oral part of described insulation sleeve is provided with loam cake.
The invention has the beneficial effects as follows:
Compared with prior art, the present invention is provided with the insulation sleeve on water-cooled cover half top, is used for liquid level partial insulation on the ingot casting, and the inner chamber of insulation sleeve is made as down infundibulate, and increase cast-solution feeding capacity is cast the liquid level central pipe even do not had shrinkage cavity fully reducing.Because housing of the present invention is processed by the high temperature stainless steel material, its crustless sandwich is provided with thermal insulating warm-keeping layer, has to delay to cast the liquid temp characteristics of decline rapidly.Adopting the present invention to cast can one-shot forming, have simple in structure, be easy to process, production efficiency height and the high characteristics of yield rate.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an operation principle sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explain.
Referring to Fig. 1,2, a kind of magnesium lithium alloy ingot casting is prevented the shrinkage cavity attemperator, includes an inner chamber and is upside down funnel shape insulation sleeve 1, and the both sides of insulation sleeve 1 are provided with regulates support 2, and the effect of regulating support 2 is to regulate deeply the cast degree of depth of liquid level of insulation sleeve 1.
The lower inner cavity wall 3 of described insulation sleeve 1 and the angle a between the last internal chamber wall 4 are 10 °～20 °.
Described insulation sleeve 1 extend into the degree of depth of 20～50mm below the casting liquid level.
Described insulation sleeve 1 adopts the high temperature stainless steel material to process.
Be provided with the exhausted pad insulating layer 5 of asbestos in the housing of described insulation sleeve 1.
The upper oral part of described insulation sleeve 1 is provided with loam cake 6.
Operation principle of the present invention is:
During use, the present invention is positioned over magnesium lithium alloy, and to water ingot mould suitable for reading.Extend into 20 ~ 50 ㎜ degree of depth below the casting liquid level through regulating support 2 adjustings, because intracavity space of the present invention and angle raise the cast-solution liquid level.The part that the cast-solution liquid level raises is the local water-cooled that breaks away under exhausted pad insulating layer effect.Slow down cooling velocity, improve the solution feeding capacity, with the shrinkage cavity problem that prevents that cooling fast from causing.
