Abstract
The utility model discloses a side entering type graphite crystallizer, which comprises a cylindrical outer sleeve and a core shaft arranged in the outer sleeve, wherein the core shaft is divided into a base and a working section, the base is tightly connected with the cylindrical outer sleeve, an annular molding channel is formed between the outer wall of the working section and the inner wall of the outer sleeve, and a plurality of liquid inlet holes communicated with the molding channel are distributed on an outer sleeve wall body close to the base of the core shaft. The graphite crystallizer has the characteristics of long service life and good surface quality of a product.
Description
Technical field
The utility model belongs to a kind of non-ferrous metal processing and uses graphite jig, relates in particular to the side entering type graphite crystallizer that is applied on the continuous casting furnace.
Background technology
The copper pipe strand is become a useful person continuous casting and rolling method in the technology because the advantage that cost is low, energy consumption is little, efficient is high has obtained very fast development.Employed graphite crystallizer as shown in Figure 1 on the present continuous casting furnace, have tubular overcoat 01 and inner mandrel 02 thereof, form annular channel 04 between overcoat and the mandrel, be provided with some inlet openings 03 at the mandrel tail end, copper liquid is introduced in the annular channel by the inlet opening forward.The technical staff finds that in the production of reality this graphite jig is very low service life, and the ingot casting surface of production is crude, causes production cost to improve unstable product quality.Therefore be necessary existing graphite crystallizer is improved, to improve its service life.
Summary of the invention
Problem to be solved in the utility model is exactly at existing graphite crystallizer low defective in service life, and the side entering type graphite crystallizer is provided, and has long service life, characteristics that product surface quality is good.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the side entering type graphite crystallizer, comprise the overcoat of tubular and be located at the interior mandrel of overcoat, described mandrel is divided into base and active section, described base closely is connected with the tubular overcoat, form the shaping channel of ring-type between active section outer wall and the outer casing inner wall, it is characterized in that: be distributed with the inlet opening that several communicate with shaping channel near on the overcoat wall body of mandrel base.
Preferably, described inlet opening is obliquely installed to the active section direction of mandrel.
Preferably, the tilt angle alpha of described inlet opening is 30 °～45 °.
Preferably, annular distribution has 4～6 inlet openings on the overcoat wall body.
Preferably, the aperture of described inlet opening is 10mm～12mm.
Preferably, the active section of described mandrel is designed to diminished shaft, and its tapering β is 1 °～2 °.
Preferably, the base of described mandrel adopts the graphite pin to be connected with overcoat.
The beneficial effects of the utility model: on the coat with the inlet opening setting, copper liquid rely on self on the pressure side in the shaping channel of introducing graphite crystallizer, utilize the inside and outside pressure reduction that forms of shaping channel, copper liquid crystal grain hoop is flowed, reach interior tissue homogenize, refinement, thereby the raising die life, the roughness of reduction product surface; Find in the application of reality, compare with original graphite crystallizer that the single output of graphite crystallizer provided by the utility model has improved about 2 times, operating efficiency improves, and production cost reduces, and makes the batch process of product obtain favourable guarantee.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of existing graphite crystallizer;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the left view of Fig. 2.
The specific embodiment
With reference to Fig. 2,3, the utility model is the side entering type graphite crystallizer, comprise the overcoat 1 of tubular and be located at mandrel 2 in the overcoat 1, described mandrel 2 is divided into base 21 and active section 22, described base 21 closely is connected with tubular overcoat 1, form the shaping channel 4 of ring-type between active section 22 outer walls and overcoat 1 inwall, be distributed with the inlet opening 11 that several communicate with shaping channel 4 near on overcoat 1 wall body of mandrel 2 bases 21.
As follows as preferred construction: inlet opening 11 is obliquely installed to active section 22 directions of mandrel 2, and its tilt angle alpha is 30 °～45 °; Usually be distributed with 4～6 inlet openings 11 on overcoat 1 wall body, shown in Fig. 3 be 4; The aperture of each inlet opening 11 is at 10mm～12mm; The active section 22 of mandrel 2 is designed to diminished shaft, and its tapering β is 1 °～2 °; The base 21 of mandrel 2 adopts graphite pin 5 to be connected with overcoat 1.
During work, earlier overcoat 1 is embedded in the copper sheathing, is installed to again in the dummy ingot of foundry furnace, copper liquid rely on self on the pressure side in the shaping channel 4 of introducing graphite crystallizer, cast out the continuous casting of fixed dimension.The average product that adopts single mould behind the utility model has been brought up to 50 tons by original 30 tons; Surface quality of products is significantly improved, and next procedure mills face and reduced to 0.3mm by original 0.5mm, has improved lumber recovery greatly; From the creation data of above-mentioned reality as can be known, the utility model has reached increases the purpose that die life is long, improve product surface quality.
