Abstract
The utility model relates to a crystallization pipe for continuous casting of copper alloy bars, comprising a graphite pipe. The graphite pipe is provided with a copper pipe, and the copper pipe is provided with a cooling pipe. The cooling pipe and the copper pipe form a cavity. The cooling pipe is respectively provided with a water inlet and a water outlet. A taper hole is disposed in the graphite pipe, and the size of the taper hole increases along the forwarding direction of melting liquid. The cooling pipe is provided with a separator plate. As the above structures are adopted and the conicity of the graphite pipe increases along the forwarding direction of the melting liquid, the drawing of the graphite pipe is very smooth, and the graphite pipe will not be damaged when being pulled, and service lifetime of the graphite pipe can be prolonged.
Description
Technical field
The utility model relates to the crystallizer that casting industry is used, and especially relates to a kind of copper alloy bar continuous casting crystallizer.
Background technology
At present, in casting industry, crystallizer is widely used, hole in the graphite-pipe of crystallizer inside is taper, become littler and littler and its taper is direction of advance along with liquation, because in design, consider liquation smaller volume after solidifying, yet this design in actual use, because liquation solidifies for a long time and can the inwall of graphite-pipe be corroded, will make the recessed phenomenon of the inner appearance of graphite-pipe like this, diameter became big before the copper rod after solidifying was so herein compared, because the bellmouth of existing graphite-pipe diminishes in the liquation direction of advance, very unfavorable in drawing like this, might cause the fracture of graphite-pipe.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can guarantee drawing smoothly and can prolong the graphite-pipe copper alloy bar continuous casting crystallizer in service life.
The technical scheme in the invention for solving the technical problem is: a kind of copper alloy bar continuous casting crystallizer, comprise graphite-pipe, graphite-pipe is provided with copper pipe, copper pipe is provided with cooling tube, cooling tube and copper pipe form a cavity, offer water inlet and delivery port on cooling tube respectively, described graphite-pipe inside is bellmouth, and bellmouth increases along the liquation direction of advance.
Further for the flow direction that can control cooling water and the quality that can improve cooling, be provided with dividing plate in the described cooling tube.
The beneficial effects of the utility model are: adopted after the said structure, because the tapering of graphite-pipe is increasing on the direction of advance of liquation, made in drawing very wellly, can not damage graphite-pipe because of drawing, prolonged the service life of graphite-pipe.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, graphite-pipe; 2, copper pipe; 3, delivery port; 4, water inlet; 5, cooling tube; 6, water-stop sheet.
The specific embodiment
A kind of copper alloy bar continuous casting crystallizer as shown in Figure 1, comprise graphite-pipe 1, graphite-pipe 1 is provided with copper pipe 2, copper pipe 2 is provided with cooling tube 5, cooling tube 5 forms a cavity with copper pipe 2, offer water inlet 4 and delivery port 3 on cooling tube 5 respectively, described graphite-pipe 1 inside is bellmouth, and bellmouth increases along the liquation direction of advance; Be provided with dividing plate in the described cooling tube 5.
Because the cone-inverted in the graphite-pipe 1 has solved the problem that the drawing difficulty causes graphite-pipe 1 to rupture, further prolonged the service life of graphite-pipe 1.
It is emphasized that above is preferable implementation column of the present utility model, and every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
Claims (2)
