Abstract
The invention discloses an insulation structure of an aluminum alloy ingot hot-top multi-die casting device, which comprises an insulation cap and a transition ring, wherein the transition ring is used for reducing the temperature difference between molten aluminum positioned in the insulation cap and molten aluminum positioned in a graphite ring of the aluminum alloy ingot hot-top multi-die casting device, and the transition ring is arranged between the insulation cap and the graphite ring. The transition ring is arranged, so that the temperature difference between the molten aluminum positioned in the insulation cap and the molten aluminum positioned in the graphite ring is smaller. When aluminum alloys are cast, the temperature difference of the molten aluminum positioned in different positions is reduced, thereby reducing crack orientation during ingot casting.

The specific embodiment
Core of the present invention provides the at most insulation construction of die cast device of a kind of aluminium alloy cast ingot heat, can effectively reduce the crack tendence of ingot casting.Another core of the present invention provides at most die cast device of a kind of aluminium alloy cast ingot heat that comprises above-mentioned insulation construction.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
Please refer to Fig. 1, Fig. 1 is the at most structural representation of the insulation construction of die cast device of aluminium alloy cast ingot heat provided by the present invention.
The aluminium alloy cast ingot heat provided by the present invention at most insulation construction of die cast device comprises hot top 1 and transition rings, transition rings is arranged on aluminium alloy cast ingot heat at most on the crystallizer body 4 of die cast device, in hot top 1 and aluminium alloy cast ingot heat at most between the graphite annulus 2 of die cast device, and the temperature of the aluminium liquid that is positioned at hot top 1, the temperature of aluminium liquid that is positioned at transition rings and the temperature that is positioned at the aluminium liquid of graphite annulus 2 are reduced successively.
With respect to prior art, advantage of the present invention is: transition rings is set can makes the temperature of the aluminium liquid that is positioned at hot top and the temperature that is positioned at the aluminium liquid of graphite annulus differ less.When to aluminium alloy casting, reduced to be positioned at the temperature difference of the aluminium liquid of diverse location, thus the crack tendence when having reduced ingot casting; And reduced the brilliant tendentiousness that generates of featheriness.
Transition rings can be ceramic adapter ring 3, makes the wall thickness of ceramic adapter ring 3 greater than the wall thickness of graphite annulus 2.And the material of preferential Ceramics adapter ring 3 is N17.The hardness of N 17 potteries is high, high, the chemical Heat stability is good of intensity; And so arrange, simple in structure, can improve the processability of ingot casting.
Certainly, transition rings also can be the graphite adapter ring, makes the wall thickness of graphite adapter ring greater than the wall thickness of graphite annulus 2; Perhaps graphite annulus 2 is processed into cascade ring, to reduce the temperature difference etc., this paper repeats no more.
