Description
Technical field
The present invention relates to amorphous band preparation field, more particularly to a kind of amorphous crystallizer copper sleeve cooling that can axially shunt
Structure.
Background technology
Amorphous band has a wide range of applications market prospects as the core material in novel energy-saving power electronic equipment.
Amorphous crystallizer is a kind of typical roll-type structure of mosaic, i.e., be set in outside support roller outside crystallizer copper sleeve.Wherein, support roller is more
Using 45# steel, copper sheathing is generally beryllium copper or chromium-zirconium-copper, in amorphous band preparation process, crystallizer copper sleeve as heat absorption device and
The crucial place of band initial formation, the reasonability of its interior cooling structure design will directly determine the quality of surface quality of strips.
The Chinese patent of Patent No. 201110095389.9 discloses a kind of amorphous crystallizer, is in copper sheathing inner periphery side
Set up several axially through Rectangular Water Trough, however, when being produced using the amorphous crystallizer, cooling water is along crystallizer
In the flow process of copper sheathing axial direction, water temperature is in increase trend along its flow direction, and then causes amorphous crystallizer copper sleeve surface to cool down
The inhomogeneities of ability, is unfavorable for the raising of amorphous band yield and its surface quality.
Additionally, in amorphous band preparation process, compared with the one dimensional heat transfer characteristic with band central region based on radial direction,
Under axial heat conduction effect, strip side portion area has the Two-Dimensional Heat feature based on radial and axial heat transfer, easily makes local band
Curling (being commonly called as scollop, scallop) and embrittlement phenomenon are produced, the lifting of strip product quality is constrained.To avoid amorphous band edge area
The influence of domain Two-Dimensional Heat characteristic, to improve the cooling uniformity in amorphous band overlay area, Patent No.
201310029623.7 Chinese patent discloses a kind of amorphous crystallizer copper sleeve cooling structure, T-shape is designed in copper sheathing and is led to
Tank and T-shape regulation copper billet, the thickness degree according to copper sheathing, the copper billet of addition regulation in good time are increased by the addition for adjusting copper billet
Plus the wall thickness of amorphous crystallizer copper sleeve solves the problems, such as that the cooling capacity and inhomogeneous cooling of copper sheathing are even；Patent 201310400924.6
A kind of amorphous crystallizer is also disclosed that, the radially UNICOM's tank of the first tank, the second tank and the 3rd trough shaped in copper sheathing is cold
But water enters UNICOM's tank by water, completes the circulating cooling to copper sheathing surface molten steel.However, above-mentioned amorphous crystallizer copper sleeve is cold
But structure is the radial direction type of cooling, it is difficult to solve the problems, such as that crystallizer axial direction inhomogeneous cooling is even and tired with processing from basic
The shortcomings of difficult, design is more according to artificial experience.
The content of the invention
Make cooling water that two are axially formed in bosh symmetrically along copper sheathing body it is an object of the invention to provide one kind
Opposite direction flowing so that improve copper sheathing axial direction cooling uniformity the amorphous crystallizer copper sleeve cooling structure that can axially shunt with
Solve the deficiencies in the prior art.
The present invention is achieved through the following technical solutions goal of the invention：

The radial direction tank connected with bosh, radial direction tank is vertical with the axial tangent line where support roller, and thus, cooling water is by radially
Tank into convex shape bosh and being axially formed two reverse flowings along copper sheathing body makes copper sheathing body axially cold
But evenly, while convex shape sets the crystallizer copper sleeve equivalent to the bosh both sides horizontal segment that increased band covering
Thickness, so as to inhibit the strip side portion caused by strip side portion region Two-Dimensional Heat to crimp (scollop, scallop) and embrittlement phenomenon, profit
Improved in surface quality of strips.
Further, be additionally provided with diffluence room in the support roller, diffluence room along support roller radial direction two ends respectively with radially
Tank is connected with bosh.Thus, entrance velocity and pressure of the setting of diffluence room beneficial to each bosh in copper sheathing body
The stabilization of power, and then ensure the circumferentially upper cooling uniformity of copper sheathing body.
Further, the diffluence room is respectively communicated with 1 radial direction tank and 4~6 boshes constitute a cooling list
Unit, cooling unit distributed quantity circumferentially is 20~40.
Further, the width of the raised section 15~35mm smaller than strip width, strip width is less than bosh
Axial overall width.Thus, there is cooling water on the whole axial width of copper sheathing, the uniformity for further increasing axially cooling is protected
The heat-transfer effect of cooling molten steel and the stability of the band quality of production are demonstrate,proved.
Further, the arc length of the bosh and it is respectively 4~7mm to the depth of outer wall by the inwall of copper sheathing body
With 10~15mm.
Further, circumferentially separated by circumferential floor along copper sheathing body between the bosh, the arc length of circumferential floor
It is 5~7mm, the arc length value of circumferential floor is excessive easily to form cooling uniformity raising and the wave that focus is unfavorable in circumference at one
Take material.
Further, the radial direction tank is cooling water inlet towards support roller inwall side, and cooling water is by radial direction tank
Bosh is entered back into diffluence room, two rightabout flowings is axially formed along copper sheathing body in bosh,
Thus, it is to avoid the axial direction rising of cooler-water temperature, axially cooling is evenly to make copper sheathing body.
Further, the radial direction tank be in cylinder, its as cooling water inlet end surfaces a diameter of 10~25mm.
The amorphous crystallizer copper sleeve cooling structure that can axially shunt that the present invention is provided has the advantages that：
1) radial direction tank and bosh are respectively provided with support roller and copper sheathing body and the two is interconnected, cooling water
By radial direction tank into being axially formed two symmetrical reverse flows along copper sheathing after bosh, it is to avoid when single direction flows
The cooler-water temperature for causing (flow direction) ever-increasing phenomenon vertically, can improve amorphous crystallizer band overlay area model
Enclose interior cooling uniformity；
2) using the bosh structure of radial direction convex, bosh is by middle raised section and the horizontal segment group of both sides
Into, be equal to increased strip side portion covering both sides horizontal segment upper copper sheathing body thickness so as to inhibit amorphous band to prepare
During the strip side portion that causes by strip side portion region Two-Dimensional Heat crimp (scollop, scallop) and embrittlement phenomenon, be conducive to raising band
The surface quality of material；
3) whole copper sheathing cooling structure is reasonable in design, and difficulty of processing is moderate, and can be used for the amorphous ribbon of different in width scope
Material is produced, and is had a wide range of application.
