With the adoption of the structure, the cooling water amount of the meniscus area, the cooling intensity of the meniscus area and the heat flux density are reduced, the meniscus area is extended, the heat conduction is relatively uniform, no cooling water amount is recued as to the crystallizer wholly, the effects of reducing the cooling intensity of the meniscus area of the crystallizer and reducing the shrinkage variation amplitude of the meniscus area are exerted, the forming and growth of a continuous casting billet are more uniform, the continuous casting billet is prevented from generating the flaws or the number of the flaws of the continuous casting billet are reduced effectively, and the quality of the continuous casting billet is improved.
Description
Technical field
The present invention relates to a kind of continuous cast mold, belong to crystallizer technology field, and in particular to slab, square billet, round billet,
Shaped blank, slim slab continuous cast mold technical field.
Background technology
Continuous casting billet has various defects, and the method for preventing various defects from producing is also a lot, wherein the generation of many defects with
Key equipment-the crystallizer of continuous casting is relevant, and many defects of continuous casting billet are produced at meniscus, are derived near meniscus
Heat it is too many and derived heat is uneven, crackle and bleed-out can be caused, in particular with people to generation efficiency requirement, draw
Fast more and more higher, nearby derived heat is more violent for meniscus, and derived heat is more uneven, the crackle for thus causing and
Bleed-out probability increase is more frequent.Strand heat derives rely on taking out of for continuous cast mold cooling water, and continuous casting crystallizer copper plate is cold
But the passage of water is unanimous between the higher and lower levels, and the design of water is all consistent up and down.With the raising of pulling rate, it is desirable to total cooling
Water increases, and heat is certainly more as derived from meniscus, and heat derived from meniscus will be more uneven, and defect is naturally more
It is many, frequently.
In order to prevent and treat various defects, prior art has the technological means of various solutions.
Notification number a kind of novel crystallization device for pouring into a mould square billet for the patent document of the U of CN 203155963 is disclosed, in slab
On the basis of crystallizer, the production of square billet is realized by installing part flow arrangement so that plate slab crystallizer production product has many
Sample feature；Compared to square blank crystallizer is redesigned, the application of part flow arrangement reduces the cost of equipment；Because shunting is filled
Put with good heat conductivity, the characteristics of rapid heat dissipation, meanwhile, cooling water is passed through so that the partial heat of high-temperature molten steel is through shunting
The cooled water of device is taken away, and improves the service life of plate slab crystallizer；In the process of setting of molten steel, each several part green shell is equal
Even cooling, its growth is also more uniform, it is to avoid the generation of the defect such as strand crackle, bulge, improves the lumber recovery of strand.
But, this patent is really, using plate slab crystallizer wider, narrow side crystallizer to be inserted in width, by slab
Crystallizer is divided into several square blank crystallizers, and the narrow side crystallizer must all be cooled down because of its both sides, so both sides must all have cold
But water hole, rather than so-called shunting, above-mentioned document is big in the water-carrying capacity of meniscus surface area, and heat conduction is uneven, does not have controlling stream
The part of amount, causes heat to conduct uncontrollable, prevents crack defect effect bad.
Notification number discloses a kind of wide-surface copper plate of crystallizer of continuous slab casting machine for the patent document of the U of CN 202155493
Cooling structure, it is unreasonable for current broadside copper board of continuous casting crystallizer for thin slab blank cooling structure, cause face copper coin wide and strand temperature
The problems such as spending inhomogeneous cooling, easily cause copper coin severe crack, low life-span, slab quality defect is improved, wide to crystallizer
Face copper coin cooling water channel is optimized design, and its cooling water channel diameter reduces, quantity increases, and is distributed according to liquid steel temperature
Situation carries out reasonable layout, is effectively improved crystallizer face intensity of cooling wide, improves crystallizer face Temperature Distribution wide, reduces crystallizer
Copper coin surface temperature is poor, improves slab quality.
Tank chilling room cools down also uneven every uneven, and being changed into water hole can design that interval is uniform, and Temperature Distribution is relative
Uniformly.While cooling, in order to carry out heat conduction, employ the reduction of cooling water channel diameter, quantity increases above-mentioned patent, and root
Reasonable layout is carried out according to liquid steel temperature distribution situation, is not reduced in the water-carrying capacity of meniscus surface area, it is equally existed in bent moon
The water-carrying capacity in face region is big, and heat conduction is uneven, the part without control flow, causes heat to conduct uncontrollable, prevents crackle
Defect effect is bad.
The content of the invention
In view of this, the purpose of the present invention is directed to the deficiencies in the prior art, there is provided a kind of heat conduction is uniform, in meniscus area
Domain can control the device of cooling flow, solve that meniscus surface area heat conduction present in prior art is uneven, flow can not
Control, so as to cause the technical problem of the defects such as crackle.
To reach above-mentioned purpose, the present invention uses following technical scheme：
A kind of crystallizer, including copper coin and water tank, water tank set an intake chamber and multiple water-supplying chamber, during water tank or copper coin are set
Between be recessed, form water-cooled hot switching path, passage connects with intake chamber and water-supplying chamber, the multiple water-supplying chamber at least one set
Put in meniscus surface area, at least one is arranged on the lower section of meniscus surface area, water tank peripheral projection carries seal groove and sealing
Circle..
Preferably, the depression in meniscus area is shallower than the depression below meniscus.
Preferably, described being arranged on water-supplying chamber's connecting pipe of meniscus surface area or lower section sets valve.

Crossing valve can flow through flow at meniscus with accurate adjustment, and convenient experiment obtains accurate parameter to control defect.
4th, current flow from down to up in the present invention, and continuous casting steel billet heat transfer is good, and cooling is played a part of well, lead to
Cross setting flowmeter to measure flow, can intuitively obtain influence of the flow to defects such as crackles, so as to control suitable ginseng
Number.
5th, the present invention sets water tank backboard, can be with quick-replaceable, so as to reduce in the labour intensity for mounting and dismounting, more
It is convenient, fast.
6th, the setting of diamond block, makes copper coin be unlikely in the case where drawing is acted on water tank, deforms copper coin or water tank, while water chestnut
The tip of shape block does not influence the heat exchange of crystallizer along water (flow) direction.
In a word, Liang Ge water-supplying chamber, the opening degree of control valve are set and change meniscus surface area water-cooled hot switching path
Flowmeter in the size in gap, and observable water inlet pipe and water outlet pipe, makes meniscus surface area water-flowing amount be the total water-flowing amount of continuous cast mold
Adjust more controllable between 40%~80%, making the cooling water inflow in meniscus area reduces, meniscus area intensity of cooling reduction, hot-fluid is close
Degree reduces, and meniscus surface area extension, heat transfer is relatively uniform, and, cooling water inflow is not reduced to crystallizer generally speaking, overall cold
But ability does not change, and the factor for producing continuous casting defect in meniscus surface area is substantially reduced, and can effectively eliminate continuous casting defect.
