Embodiment
It is new to this practicality below in conjunction with attached drawing to make the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.Only this state, the utility model occur in the text or will appear from upper and lower, left and right, it is preceding,
Afterwards, the orientation such as inside and outside word, only on the basis of the attached drawing of the utility model, it is not that the specific of the utility model is limited.
As Figure 1-Figure 4, the utility model embodiment provides a kind of crystallizer, including crystallizer body 1, pinboard
2 and graphite annulus 3, the center of crystallizer body 1 is equipped with crystallization channel 11, and pinboard 2, institute are equipped with the top of the crystallization channel 11
State the lower section of pinboard 2 and be equipped with the graphite annulus 3, oil gas micropore 31 is equipped with the graphite annulus 3；The pinboard 2 is equipped with crystallization
Mouth 21, the lower side edge of the crystallization mouth 21 are equipped with downwardly projecting gas storage ring 22, the gas storage ring 22, pinboard 2 and graphite
Ring 3 is in turn connected to form gas chamber 4, and the gas chamber 4 is used to prevent molten aluminum and the junction of pinboard 2 and graphite annulus 3 from contacting.
Crystallizer provided by the utility model, including crystallizer body 1, pinboard 2 and graphite annulus 3.Wherein, pinboard 2
The diameter of crystallization mouth 21 be less than the bore of crystallization channel 11 and graphite annulus 3, the poor pinboard 2 of heat conductivility is by molten aluminum point
Two parts up and down are divided into, prevent the molten aluminum of crystallization mouth 21 lower section to be cooled the cooling of water and the molten aluminum for crystallizing the top of mouth 21 is cold
But, crystalline quality is influenced.
Preferably, oil pipe 12 and snorkel 13, the snorkel 13 and oil pipe 12 are equipped with the crystallizer body 1
It is connected to the back side of graphite annulus 3.The gas storage ring 22, pinboard 2 and graphite annulus 3 mentioned above are in turn connected to form gas chamber
4 refer to：In casting process, gas is passed through graphite annulus 3 by the snorkel 13, and gas is separated out from the front of graphite annulus 3, due to weight
Power effect accumulates in the gas storage ring 22, pinboard 2 and graphite annulus 3 and is sequentially connected in the space surrounded.Due to above-mentioned gas energy
Enough it is continuously replenished, even if portion gas is taken away by molten aluminum, also maintains to dynamic certain gas to stay in the gas chamber 4, institute
State gas chamber 4 to be used to prevent molten aluminum and the junction of pinboard 2 and graphite annulus 3 from contacting and the crystallisation by cooling that taken the lead in, and then prevent from casting
The metal solid scratch that part is first crystallized, lifts the surface quality of casting.
In order to coordinate with the gas chamber 4, the gas storage ring 22 is equipped with arc-shaped transition section 222 close to 3 side of graphite annulus.It is described
Arc-shaped transition section 222 coordinates with gas chamber 4, and making molten aluminum under the pressure of the gas, movement smoothly turns to straight down from horizontal direction
It is mobile, and steering procedure is only completed by the gas pressure in gravity and gas chamber 4, will not be contacted with the inner wall of crystallizer, reduces knot
Brilliant device influences the non-essential temperature of molten aluminum.The oil gas micropore 31 is evenly distributed in graphite annulus 3, forms graphite annulus 3
The cooling effect of hole for water spraying, is limited in the lower section of graphite annulus 3 by thermal insulation layer.Lubricating oil is separated out from oil gas micropore 31, in graphite annulus 3
Surface forms oil-bearing layer, and lubricating oil is completely burned before following molten aluminum to leave graphite annulus 3, prevents lubricating oil from entering cooling water
In, cause environmental pollution.
In order to accelerate cooling velocity of the molten aluminum in 1 lower end of crystallizer body, the crystallizer body 1 is additionally provided with hole for water spraying
14,14 circumferential array of hole for water spraying is on crystallization channel 11, positioned at the lower section of graphite annulus 3；The hole for water spraying 14 is two rows of altogether, and two
The arrangement of 14 longitudinally spaced preset distance of hole for water spraying is arranged, and the hole for water spraying 14 is obliquely installed with different angle, makes two rows of water sprays
The current that hole 14 sprays interlock up and down.Cooling water can obtain complementation when being sprayed on casting circumferential surface, be really achieved casting cooling
Uniformly without dead angle, and impact of the cooling water to cast(ing) surface is uniform, prevents that cooling water is excessive to casting local assault and causes
Casting surface defect.
Wherein, the hole for water spraying 14 is connected with cooling-water duct 17, the cooling-water duct 17 and the outside of crystallizer body 1
Connectivity part be equipped with filter screen 15, prevent the impurity in cooling water from entering, prevent impurity block hole for water spraying 14.Preferably, it is described
Hydroecium 16 is additionally provided with crystallizer body 1, the hydroecium 16 is connected with cooling-water duct 17, the aggregation before being sprayed for cooling water
And buffering, prevent from being mixed with gas in cooling water and causing hydraulic pressure suddenly to increase to cast(ing) surface and cause to damage, also shorten water spray
The length in hole 14, reduces the possibility that hole for water spraying 14 blocks, also ensure that the water velocity of each hole for water spraying 14 is consistent.
The operation principle of this crystallizer is as follows：When casting starts, dummy bar head is arranged near this crystallizer hole for water spraying 14, will be tied
Brilliant 11 bottom lock of passage.Metal bath enters above pinboard 2, is accumulated on dummy bar head and starts to contact with graphite annulus 3.
Then dummy bar head slowly moves down, until casting is completed.In casting process, the oil gas micropore 31 on 3 surface of graphite annulus starts
Lubricating oil and protective gas are separated out, metal bath starts to form the smooth surface of predetermined diameter under the limitation of graphite annulus 3.Graphite
Ring 3 itself has oiliness, and lubricating oil can burn totally during following metal bath to move down, and will not enter cooling water
In, environmental protection.Protective gas accumulates in 2 bottom of pinboard, under the guiding role of gas storage ring 22, follow-up molten aluminum after separating out
, can be to the direction transverse shifting of graphite annulus 3 after the crystallization mouth 21 of pinboard 2 enters crystallizer, arcuately changeover portion 222 is to turning
The bottom surface of fishplate bar 2 is close, and still, since protective gas is built up in gas chamber 4, metal bath will not be with graphite annulus 3 and pinboard 2
Junction contact, prevent that metal bath rapid crystallization from forming sharp metallic particles, ensure surface quality of continuous castings.Casting
Cheng Zhong, the protective gas in gas chamber 4 can be continuously obtained supplement.When metal bath enters the lower section of graphite annulus 3, hole for water spraying 14 sprays
Go out cooling water, casting is quickly cooled down.Due to the presence of pinboard 2, the metal bath above pinboard 2 is cooled water
Influence it is less, can adapt to the casting speed demand under different technology conditions.
Above disclosed is only a kind of the utility model preferred embodiment, cannot limit this practicality with this certainly
New interest field, therefore the equivalent variations made according to the utility model claims, still belong to what the utility model was covered
Scope.
