The upper water jacket is of a double-layer structure. The crystallizer can enable exhausting and feeding effects of all regions of an ingot to be consistent and the thickness of kish of the ingot on the same cross section to be uniform. An upper water cavity and a lower water cavity are adopted for separating primary water and secondary water; industrial purified water is used as primary cooling water and does not scale in the service life of the crystallizer. Circulating turbid water is used as the secondary cooling water; the cooling effect of the ingot is not affected by the hardness of the secondary cooling water; and the equipment investment and the production and operating costs can also be substantially reduced.
Description
Technical field
The utility model relates to a kind of crystallizer, especially relates to the double-deck water cavity crystallizer of vertical D.C.casting.
Background technology
Existing big specification (diameter surpasses Φ 250mm) the vertical D.C.casting structure of mould of alloy comprises liner and water jacket, forms water cavity between water jacket and the liner.Though existing structure of mould is simple, has the shortcoming that the life-span is short, the ingot casting dimensional accuracy is low.And one time intensity of cooling is higher, is not suitable for producing big specification, heat conductivility than red copper difference or the more sensitive alloy cast ingot of temperature.When producing this type of ingot casting, be prone to defectives such as cold and hot crackle, ingot casting density be low, cause the ingot casting lumber recovery low.
The utility model content
In view of this, the purpose of this utility model provides the double-deck water cavity crystallizer of vertical D.C.casting, and it can effectively address the above problem.
Above-mentioned purpose realizes by following proposal:
The double-deck water cavity crystallizer of a kind of vertical D.C.casting, it comprises liner, copper sheathing and water jacket from inside to outside successively, it is characterized in that, described water jacket comprises top water jacket and bottom water jacket, described top water jacket and bottom water jacket are separate, put in described upper water and to be provided with water inlet and delivery port, on the water jacket of described bottom, be provided with delivery port, and have water jet in water jacket inboard, described bottom.
According to above-mentioned crystallizer, it is characterized in that described top water jacket is a double-decker.
According to above-mentioned crystallizer, it is characterized in that, comprise toroidal membrane in the water jacket of described top, form inside and outside two water cavities in described toroidal membrane both sides, and, the water inlet of described top water jacket is communicated with by a plurality of through holes that are opened on the described toroidal membrane with the water cavity of inboard, and described two water cavities are communicated with by a plurality of through holes of toroidal membrane.
According to above-mentioned crystallizer, it is characterized in that be communicated with the circumference setting of a plurality of through holes of described water inlet and described inboard water cavity along described toroidal membrane, the through hole that is communicated with described two water cavities is also along the circumference setting of described toroidal membrane.
The beneficial effects of the utility model: it is to make crystallizer obtain identical cooling effect along circumferential zones of different that the utility model adopts the benefit of double-deck water cavity, makes ingot casting respectively distinguish exhaust, feeding effect unanimity, and the ingot casting scull thickness on same cross section is even.Adopt up and down that the purpose of water cavity is that a water is separated with secondary water, primary cooling water employing technical pure water purification is at crystallizer non-scaling in useful life period.Secondary cooling water adopts the circulation muddy water, and the hardness of secondary cooling water does not influence the cooling effect of ingot casting, can also significantly reduce equipment investment and production and operation cost.
Description of drawings
Fig. 1 is a structure of mould schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, double-deck water cavity crystallizer of the present utility model comprises liner 1, copper sheathing 1a, top water jacket 2, bottom water jacket 2' and toroidal membrane 3, water cavity 8 is a cooling chamber between copper sheathing 1a and the toroidal membrane 3, and water cavity 8 is outer water cavity 10 between top water jacket 2 and the dividing plate 3.Between the bottom of top water jacket 2 middle parts and toroidal membrane 3, be primary cooling water water inlet water annulus 6.Be communicated with by passage 7 between primary cooling water water inlet water annulus 6 and the water cavity 8.Be communicated with by passage 9 between water cavity 8 and the outer water cavity 10.The water inlet 4 and the delivery port 5 that are provided with primary cooling water respectively at the lower left quarter and the upper right quarter of water jacket.
Between crystallizer copper sleeve 1a and bottom water jacket 2' is secondary cooling water annular water chamber 12, and the bottom of water cavity 12 has a circle secondary cooling water delivery port 13, and the lower right side of bottom water jacket 2' is communicated with the water inlet 11 of secondary cooling water.
The effect in primary cooling water chamber, top 8 is to provide triphasic cooling procedure to alloy melt and ingot casting scull.The phase I cooling procedure is that the high-temperature fusant that enters in the crystallizer is cooled off, and must be cold alloy melt; The second stage cooling procedure is that the alloy that is in the solid-liquid two-phase section is forced cooling, and the gas in crystallization forward position position stability, the two-phase section can effectively be overflowed along the liquid cave; The phase III cooling procedure is to make the alloy outside that is in solid-liquid two-phase region form continuous scull, and the solid phase area of scull inside can access effective feeding.The back taper structure of crystallizer is consistent with the linear shrinkage characteristic of ingot solidification, in the time of reducing and eliminate because of ingot solidification, the air gap that may form between ingot casting and crystallizer inwall improves the heat exchange condition between ingot casting scull and the crystallizer inwall, strengthens one time cooling procedure.
The effect of bottom secondary cooling water annular water chamber 12 is the ingot casting that forms the full surface scull and pull out crystallizer to be carried out secondary force cooling, finally obtains pore-free, does not have loose high-quality ingot casting.
The crystallizer primary cooling water adopts the technical pure water purification, at crystallizer non-scaling in useful life period.Be provided with water inlet 4, delivery port 5, water feeding pressure, water temperature, the water yield can automatically adjust according to alloy casting temperature, casting speed, ingot casting specification.The crystallizer secondary cooling water adopts the circulation muddy water, is provided with water inlet 11, delivery port 13, and water feeding pressure, water temperature, the water yield can automatically adjust according to alloy casting temperature, casting speed, ingot casting specification.
In addition, in order to make the life-span of crystallizer prolong, liner 1 is plating Chrome layer, and copper sheathing 1a is that material is Cu-Zr or Cu-Cr-Zr alloy copper sheathing, and top water jacket 2 and dividing plate 3 are the processing steel-casting
To produce the BFe30-1-1 alloy cast ingot is example, use this crystallizer can produce that density height, surface quality are good, pore-free does not have loose high-quality BFe30-1-1 alloy cast ingot, improve following process operation lumber recovery, improved tubing quality and corrosion resisting property, be to improve the white copper condenser tube quality and the effective measures in service life, have higher economic value and social benefit.
