Abstract
The utility model discloses a horizontal continuous casting graphite crystallizer which comprises an outer sleeve and a core rod, wherein the tail portion of the core rod is connected on the outer sleeve, a ring channel is arranged between the core rod and the outer sleeve, and the side wall of a connecting position of the outer sleeve and the ring channel is provided with a liquid inlet. The horizontal continuous casting graphite crystallizer is characterized in that the liquid inlet and the inner wall of the outer sleeve are in a vertical tangent line state, the liquid inlet is uniformly arranged on the side wall of the outer sleeve, which is apart from the bottom end of graphite for 8-12mm, shearing force and centripetal force are produced through using the pressure difference of the inner and the outer portion of the channel, thereby leading grains in molten metal to flow and rotate on a same ingoting surface according to a same direction, achieving to homogeneous internal organization and refined grains, prolonging the service life of dies, and increasing the production efficiency. Simultaneously, the horizontal continuous casting graphite crystallizer also solves the problems produced by using new process that the investment of equipment is high, the power consumption is more, the operation is extremely difficult, and the batch production can not be formed.
Description
Technical field
The utility model relates to a kind of crystallizer that the round copper pipe base is used of producing, particularly a kind of novel horizontal continuous casting graphite crystallizer.
Background technology
At present, copper pipe strand molding technology thereof is two kinds basically both at home and abroad, the one, and the continuous casting and rolling method, another is an extrusion.The continuous casting and rolling method is compared with extrusion, and it is low to have a cost, and energy consumption is little, and characteristics such as lumber recovery height are widely used, and are developed faster.But owing to also exist defective on the employed graphite crystallizer structural design in process of production, cause the metallographic structure of ingot casting inhomogeneous, phenomenons such as peeling, crackle appear in casting billet surface, directly influence quality, production efficiency and the production cost of copper pipe product.
The disclosed horizontal continuous casting graphite crystallizer of Chinese patent ZL200720183751.7, the copper pipe casting billet surface of its continuous casting is smooth, can not have the crystallization line, and has improved Forming Quality.But because its graphite mo(u)ld copper water inlet place is the straight hole of bottom, over against the channel of holding furnace, form bubble easily, can not form stirring simultaneously before solidifying, the metallographic structure in the same cross section of ingot casting is inhomogeneous, influences the mechanical property and the deep processing of product.
Along with electromagnetic field is applied in the horizontal casting process, the tissue and the performance of horizontally continuous casting copper pipes base all are greatly improved, the inside and outside defective of the method for patent copper and the horizontal electromagnetic continuous-casting of copper alloy strand and device (publication number CN1416981A) a kind of minimizing copper that provides and copper alloy cast tube base, improve surface quality, improve interior tissue, make crystal grain spare matter, refinement, prolong the service life of mould, a kind of horizontal continuous casting method and the device of enhancing productivity.But because when applying ac magnetic field changing slab quality in the horizontal casting process, some technical indicators are stable inadequately, and equipment investment is bigger, power consumption is more, tool changing complexity during the conversion specification, operation is difficulty comparatively, can't form the ability of batch process for this reason.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of horizontal continuous casting graphite crystallizer at the prior art present situation, can improve casting in bronze ingot interior tissue, makes crystal grain spare matter, and refinement in the service life of prolongation mould, can form batch process again.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of horizontal continuous casting graphite crystallizer, comprise that overcoat, afterbody connect plug on the coat, be provided with the circular passage between plug and the overcoat, the sidewall of the junction of overcoat and circular passage is provided with inlet, it is characterized in that: described inlet is vertical secant-shaped with outer casing inner wall.
As improvement, described inlet is arranged on apart from 8-12mm place, graphite bottom, 4-6 altogether.
Preferably, described inlet is evenly distributed on the sidewall of overcoat and junction, circular passage, and the angle of distribution is 60 °～90 °, and the aperture is between Φ 6mm-Φ 8mm.
Improve, described overcoat adopts graphite pins to be connected with plug again.
Compared with prior art, advantage of the present utility model is: adopt inlet evenly to be arranged on the side-walls of overcoat apart from graphite bottom 8-12mm, utilize the inside and outside pressure reduction of passage, produce shear force and centripetal force, crystal grain in the molten metal is flowed and rotation by equidirectional at same ingot casting face, reach the even matter of interior tissue, grain refinement, prolong the service life of mould, enhance productivity; Simultaneously, solved also that the equipment investment that technology produced is big, power consumption is many, operation difficulty and can not form the problem of batch process comparatively.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2: a kind of horizontal continuous casting graphite crystallizer, comprise that inlet 1, overcoat 2, afterbody are connected plug 5, the graphite pins 4 on the overcoat 2, overcoat 2 is connected and fixed installation for convenience detach with plug 5 by graphite pins 4; Be provided with circular passage 3 between plug 5 and the overcoat 2, overcoat 2 is provided with inlet 1 with the sidewall of the junction of circular passage 3, inlet 1 is vertical secant-shaped 6 with overcoat 2 inwalls, it is exactly the diameter of inlet 1 vertical overcoat 2, simultaneously, the sideline, outside of inlet 1 is the tangential direction of this diameter, inlet 1 is arranged on overcoat 2 apart from 8-12mm place, graphite bottom, 4-6 altogether, 4-6 inlet 1 is evenly distributed on the sidewall of overcoat 2 and 3 junctions, circular passage, the angle A that distributes is 60 °～90 °, and the aperture prevents that clogging from appearring in liquation between Φ 6mm-Φ 8mm; When molten metal passes through inlet 1, because each inlet 1 is the plumb cut shape with overcoat 2 inwalls, pressure differential appears inside and outside the circular passage 3, shear force and the centripetal force of utilizing molten metal to produce, can make the crystal grain in the liquation flow and rotate by equidirectional at same ingot casting face, thereby impel broken crystal to become again the core of crystallization nucleation, and form equiaxed crystal, reach grain refinement; Simultaneously, the liquation cooled and solidified becomes ingot casting to pull out, and the pressure reduction in the passage remains unchanged, and reduces the thermograde of liquation in the pipe process of setting, makes the even matter of interior tissue in the same cross section of ingot casting, refinement.
