Description
Technical field
The present invention relates to continuous casting installation for casting cooling technology field, in particular to a kind of crystallizing wheel water jacket cooling system.
Background technology
It is presently used for production copper alloy, aluminium alloy electrician and generally includes steel with pole stock, the conticaster of sheet material its crystallizer
Band, wheeled steel, circumference are provided with the crystallizing wheel of annular groove.Steel band by multiple steel band Wheel-guidings, tighten and be adjacent to crystallizing wheel,
The groove outer rim of crystallizing wheel is closed by steel band, is formed along the circumferential die cavity that throwing outlet is extended to by casting gate of crystallizing wheel, gold
Category liquid is forced crystallisation by cooling by pouring pot in die cavity and forms strand from after casting gate injection, and the strand of formation is from throwing outlet drawing
Go out.
When pour pot metal liquid pour into a mould by casting gate phase crystallizing wheel when, metal liquid cooling shaping in crystallizing wheel, show
The type of cooling of some sheet material tyre type casting machines is spraying cooling, although water can be with sectional-regulated, the cooling water of spray
Mix at once, be difficult to form clear and definite subregion from top to bottom, the requirement to crystallization processes is difficult to.
The content of the invention
It is cold to the sufficiently cool of crystallizing wheel subregion it is an object of the invention to provide a kind of crystallizing wheel water jacket cooling system
But water completely attaches to cooling with crystallizing wheel internal and external circumference, to solve the above problems.
To realize the object of the invention, the technical scheme for using for：A kind of crystallizing wheel water jacket cooling system, including crystallizing wheel,
Steel band, steel band closing crystallizing wheel outer rim forms casting die cavity；
The periphery of steel band is provided with outer coolant jacket, and the inner headed face of crystallizing wheel is provided with interior coolant jacket；Outer coolant jacket and interior coolant jacket are equal
Including cooling body, cooling body is the arc matched with crystallizing wheel；
Form outer cooling chamber between the cooling body and steel band of outer coolant jacket, the cooling body of interior coolant jacket and the inner headed face of crystallizing wheel it
Between formed in cooling chamber；Outer cooling chamber and interior cooling chamber are circumferentially divided at least three circumferential cooling zones；
The cooling body inner headed face of outer each circumferential cooling zone of cooling chamber and the cooling body periphery of each circumferential cooling zone of interior cooling chamber are equal
It is intervally arranged on crystallizing wheel axial direction with the multiple shunt bars for circumferentially setting, and multiple shunt bars；Each circumferential cooling zone
It is equipped with the water inlet and delivery port positioned at shunt bar two ends.
Further, left between the shunt bar and steel band periphery and between shunt bar and crystallizing wheel inner headed face
Gap.
Cooling water enters through shunt bar guiding shunting from water inlet, cooling water is spread over cooling surface everywhere, by thin
Small gap is also more preferably easy to the infiltration of water to shunt, while the directly contact avoided between shunt bar and steel band and crystallizing wheel is rubbed
Wipe.
Further, each circumferential cooling zone of the outer cooling chamber and interior cooling chamber is divided axially at least three along crystallizing wheel
Individual axial cooling zone；The shunt bar two ends of each axial cooling zone divide equally cloth and set the water inlet and delivery port.
What the rib because of crystallizing wheel by wheel body and installed in wheel body both sides was constituted, annular groove is opened in that wheel body is cylindrical and and steel
Band enclosed shape forming cavity.This causes that the rib junction rapid heat dissipation of wheel body both sides, the i.e. two side portions of die cavity are disperseed than pars intermedia
Hot fast, middle part can only lean on steel band and crystallizing wheel to conduct heat, and radiating is slow.And the subregion on axial direction is realized by the water of each axial cooling zone
Flow is controlled to adjust, and makes balanced cooling on die cavity width, reaches more preferably cooling effect.
Further, two neighboring axial cooling zone by divider divide, and between divider and steel band periphery, with
And leave gap between divider and crystallizing wheel inner headed face.By minim gap, there is cooling water trickle between each axial cooling zone
Seepage, forms the dynamic equilibrium state of cooling.Shunt bar length is less than divider.Shunt bar in same axial cooling zone is in axial direction
Uniform intervals are distributed.
Further, two neighboring circumferential cooling zone is separated by bulkhead seal, and the both sides of dividing plate are provided with sealing strip.Sealing
Separate, the cooling water independent control regulation of each circumferential cooling zone, the different states of cooling requirement of each processing step of good correspondence,
Sealing strip circumferentially rubs cooling chamber circumferentially spaced with crystallizing wheel and steel band, will not be shifted over because of the rotation of crystallizing wheel.
Further, the outer coolant jacket cooling body periphery and steel band between and interior coolant jacket cooling body periphery
Sealing strip is equipped between crystallizing wheel.
Further, cooling body arc length of the cooling body arc length of the interior coolant jacket more than outer coolant jacket.Phase after pouring
The temperature control stage, can rely primarily on it is interior it is cold control crystallizing wheel and strand temperature, reach suitable technological temperature.
Further, also including base, the axle sleeve being fixed on base, the feed pipe being through in axle sleeve；Crystallizing wheel is rotated
It is supported on axle sleeve, feed pipe is connected by pipeline with each water inlet of interior cooling chamber.
Further, the cooling body center of circle of the interior coolant jacket has installation set, is connected between installation set and cooling body
Gusset, installation set is loaded on outside axle sleeve.
Further, also including the upper fulcrum outside outer coolant jacket, connecting rod, bearing and linear driving element；Connecting rod
One end be articulated with fulcrum, the other end is articulated with the cooling body top of outer coolant jacket；Linear driving element is hydraulic cylinder or gas
Cylinder；The cylinder body of hydraulic cylinder or cylinder is articulated with bearing, and piston rod is articulated with the cooling body bottom of outer coolant jacket.
Beneficial effects of the present invention：
1st, by the inside and outside coolant jacket on crystallizing wheel internal and external circumference, the subregion cooling on circumference is realized, in correspondence casting process not
With the parameter such as stage different chilling temperature, cooling water is spread over cooling surface everywhere by the guiding shunting of shunt bar,
Sufficiently cool, subregion independent control realizes the component regulation of each region water, and more preferably corresponding to satisfaction casting crystallization processes will
Ask；
2nd, by the subregion on axial direction, i.e., the zonal control cooling on die cavity width is realized balanced cold on strand width
But, it is to avoid both sides cooling is fast, cooling during rolling is slow and influence the strand to cast crystalline quality, axial and circumferential both direction is divided respectively
Area cools down, and reaches the more preferably cooling effect of matching casting process.
