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 pole stock, the conticaster of plank its crystallizer and generally includes steel
Band, wheeled steel, circumference are equipped 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 cavity that throwing outlet is extended to by casting gate of crystallizing wheel, gold
Belong to liquid to be forced in cavity crystallisation by cooling after casting gate injection by pouring to stew and is formed strand, the strand of formation is from throwing outlet drawing
Go out.
When pour stew metal liquid pour into a mould by casting gate phase crystallizing wheel when, metal liquid is cooled and shaped in crystallizing wheel, show
The type of cooling of some plank tyre type casting machines is spraying cooling, although water can be sectional-regulated, the cooling water of spray
It mixes at once, is difficult to form specific subregion from top to bottom, the requirement to crystallization processes is difficult to realize.
Invention content
The purpose of the present invention is to provide a kind of crystallizing wheel water jacket cooling systems, and crystallizing wheel subregion is fully cooled, cold
But water is completely attached to crystallizing wheel internal and external circumference and is cooled down, to solve the above problems.
Purpose to realize the present invention, the technical solution used for：A kind of crystallizing wheel water jacket cooling system, including crystallizing wheel,
Steel band, steel band closing crystallizing wheel outer rim form casting cavity；
The periphery of steel band is equipped with outer coolant jacket, and the inner headed face of crystallizing wheel is equipped with interior coolant jacket；Outer coolant jacket and interior cooling
Set includes cooling body, and cooling body is and the matched arc of crystallizing wheel；
Outer cooling chamber, the cooling body of interior coolant jacket and the inner circle of crystallizing wheel are formed between the cooling body and steel band of outer coolant jacket
Cooling chamber in being formed between face；Outer cooling chamber and interior cooling chamber are circumferentially divided at least three circumferential cooling zones；
The cooling body inner headed face of each circumferential cooling zone of outer cooling chamber and the cooling body outer circle of each circumferential cooling zone of interior cooling chamber
Face is respectively provided with the multiple shunt bars circumferentially set, and multiple shunt bars are intervally arranged in crystallizing wheel axial direction；It is each circumferential cold
But area is equipped with the inlet and outlet positioned at shunt bar both ends.
Further, between the shunt bar and steel band periphery and between shunt bar and crystallizing wheel inner headed face there are
Gap.
Cooling water, which enters to guide through shunt bar from water inlet, to be shunted, and cooling water is made to spread over cooling surface everywhere, by thin
Small gap also more preferably shunts, while avoid being in direct contact between shunt bar and steel band and crystallizing wheel and rub convenient for the infiltration of water
It wipes.
Further, each circumferential cooling zone of the outer cooling chamber and interior cooling chamber is divided axially at least three along crystallizing wheel
A axial direction cooling zone；The shunt bar both ends of each axial direction cooling zone divide equally cloth and set the inlet and outlet.
It is formed because of rib of the crystallizing wheel by wheel body and mounted on wheel body both sides, annular groove is opened in wheel body outer circle and and steel
Band enclosed shape forming cavity.This causes the rib junction rapid heat dissipation of wheel body both sides, i.e. the two side portions of cavity are disperseed than middle part
Hot fast, middle part can only lean on steel band and crystallizing wheel to conduct heat, and heat dissipation is slow.And the subregion in axial direction realizes the water by each axial cooling zone
Flow control is adjusted, and is made balanced cooling in cavity width direction, is reached more preferably cooling effect.
Further, two neighboring axial cooling zone is divided by divider, and between divider and steel band periphery, with
And there are gaps between divider and crystallizing wheel inner headed face.By minim gap, there is the cooling water subtle between each axial direction cooling zone
Leakage forms the dynamic equilibrium state of cooling.Shunt bar length is less than divider.Shunt bar in same axial direction cooling zone is in axial direction
It is evenly spaced on.
Further, two neighboring circumferential cooling zone is separated by bulkhead seal, and the both sides of partition board are equipped with sealing strip.Sealing
Separating, the cooling water independent control of each circumferential direction cooling zone is adjusted, the different states of cooling requirement of good each processing step of correspondence,
Cooling chamber circumferentially spaced with crystallizing wheel and steel band is circumferentially rubbed, will not be displaced due to the rotation of crystallizing wheel by sealing strip.
Further, between the cooling body periphery of the outer coolant jacket and steel band and cooling body periphery of interior coolant jacket
Sealing strip is equipped between crystallizing wheel.
Further, the cooling body arc length of the interior coolant jacket is more than the cooling body arc length of 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, pedestal, the axle sleeve being fixed on pedestal, the feed pipe being through in axle sleeve are further included；Crystallizing wheel rotates
It is supported on axle sleeve, feed pipe is connect 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, upper fulcrum, connecting rod, bearing and the linear driving element outside outer coolant jacket are further included；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 on bearing, and piston rod is articulated with the cooling body lower part 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, corresponding casting process are realized
The parameters such as different cooling temperature of middle different stage make cooling water spread over each of cooling surface by the guiding shunting of shunt bar
Place, is fully cooled, subregion independent control, realizes that the component of each region water is adjusted, more preferably corresponding to meet casting crystallization work
Skill requirement；
2nd, by the subregion in axial direction, i.e., the zonal control cooling in cavity width direction is realized equal on strand width
Weighing apparatus cooling, both sides is avoided to cool down, and fast, cooling during rolling is slow and influences strand casting crystalline quality, point of axial and circumferential both direction
Other subregion cooling reaches the more preferably cooling effect of matching casting process.
