Abstract
The invention relates to a heat conduction device of a DC casting system, in particular to a heat conduction device of a crystallizer used for enabling aluminum alloy liquid to be solidified and crystallized in the DC system. The heat conduction device comprises the crystallizer, water inlet holes in the crystallizer, water cavities connected with the water inlet holes and graphite rings on the back portions of the water cavities. The heat conduction device is characterized in that the water inlet holes are arranged in two rows, one water cavity and one graphite ring are sequentially connected on the back portion of each row of water inlet holes, and the water cavities and the graphite rings on the back portion of the upper row of water inlet holes and the lower row of water inlet holes are communicated. The heat conduction device is good in heat conduction performance and capable of improving cooling effect, and enables a casting ingot to be compact in structure and smooth in surface.
Description
Technical field
The present invention relates to a kind of DC casting system heat-transfer device, especially relate to the crystallizer heat-transfer device that a kind of DC system makes the moulding of aluminium alloy liquid solidification and crystallization.
Background technology
Existing DC casting system heat-transfer device has only single inlet opening, so single hydrophthalmia; Water shortage; And then water cavity volume thereafter is little, thereby the heat conductivility of cooling water is poor, because the graphite annulus height at rear portion is low; Since the process of ingot casting crystallization be by circumferential surface to the center, expand gradually to top by the bottom.Along with the continuous derivation of heat, crystallization is carried out to the melt depths gradually, existing structure, heat conductivility is bad, makes the ingot casting rough surface, occur easily such as leak aluminium, draw trace or drawing crack, defectives such as cold shut, surface pinholes.Also do not overcome at present the device of this defective.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of raising good heat conductivity, ability enhanced cooling are provided, make ingot casting compact structure, ganoid a kind of crystallizer heat-transfer device.
The present invention realizes in the following manner:
A kind of crystallizer heat-transfer device, it comprises crystallizer, the inlet opening in the crystallizer, the water cavity that links to each other with the inlet opening, the graphite annulus at water cavity rear portion is characterized in that: above-mentioned inlet opening is double;
Rear portion, said every row inlet opening all is connected with water cavity and graphite annulus successively, and the water cavity and the graphite annulus at rear portion, two rows inlet opening communicate.
The present invention has following effect:
1) unique, the good cooling results of structure: it comprises crystallizer device provided by the invention, the inlet opening in the crystallizer, the water cavity that links to each other with the inlet opening; The graphite annulus at water cavity rear portion; It is characterized in that: above-mentioned inlet opening is double, increases the amount of passing through that water hole quantity can significantly improve cooling water, strengthens the secondary cooling water injection flow; Improve the structural heat conducting performance, favorable cooling effect is provided.
2) guaranteed best ingot casting surface: device provided by the invention all is connected with water cavity and graphite annulus successively at rear portion, every row inlet opening; And the water cavity and the graphite annulus at rear portion, two rows inlet opening communicate; Strengthen the inner water cavity volume of crystallization; Can improve the cooling effect of a water-cooled, strengthen the performance of cooling water, guarantee best ingot casting surface through the heat conduction of crystallizer cavity.
3) eliminated cold shut, knob, draw defectives such as trace, surface pinholes: device provided by the invention all is connected with water cavity and graphite annulus successively at rear portion, every row inlet opening; Thereby crystallizer graphite annulus height increases; Increased effective cooling height, the width of intermediate zone also increases, and provides sufficient nascent hull shape to become the zone; Make the ingot casting surface perfect more, eliminated cold shut, knob, draw trace, defective such as surface pinholes.
4) improved heat conductivility: device provided by the invention adopts big die cavity, big flow, more effectively cools off highly; Purpose is to strengthen in the crystallizer once, secondary water-cooled effect; Make ingot casting solidify the nascent shell of formation; Be within the downward heat conduction distance, reach best heat conductivility, can solidify at once, contraction, moulding.Since the process of ingot casting crystallization be by circumferential surface to the center, expand gradually to top by the bottom.Along with the continuous derivation of heat, crystallization is carried out to the melt depths gradually, good DC conductive structure with compare with outmoded structure, can effectively improve the heat conductivility of structure.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
A kind of crystallizer heat-transfer device, it comprises crystallizer 1, the inlet opening 2 in the crystallizer 1, the water cavity 3 that links to each other with inlet opening 2, the graphite annulus 4 at water cavity 3 rear portions, as shown in Figure 1: above-mentioned inlet opening 2 is double;
2 rear portions, said every row inlet opening all are connected with water cavity 3 and graphite annulus 4 successively, and the water cavity 3 at 2 rear portions, two rows inlet opening communicates with graphite annulus 4.
The graphite annulus of the invention provides large-scale water cavity, the big flow in two water hole, increasing, enough cooling height.As shown in Figure 1: the crystallizer material is an aluminium matter; The quantity of inlet opening is doubled, change double water inlet simultaneously into by single water hole; The volume of corresponding increase cooling water cavity; The height of graphite annulus is increased to 20mm by 15mm.
Claims (2)
