Field prospect.Wherein, the electric equipment products noise that causes because of amorphous band surface quality defect is big, high cost the problems such as, be always stranded
The bottleneck for disturbing domestic amorphous enterprise product upgrading is located.In amorphous band preparation process, crystallizer copper sleeve is used as heat absorption device
And the crucial place of band initial formation, the reasonability of its interior cooling structure design will direct decision surface quality of strips it is good
It is bad.
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, to improve amorphous crystallizer cooling uniformity, the Chinese patent of Patent No. 201310029623.7 is disclosed
A kind of amorphous crystallizer copper sleeve cooling structure, designs T-shape water-flowing trough in copper sheathing and T-shape adjusts copper billet, according to copper sheathing
Thickness degree, in good time addition adjusts copper billet, and the wall thickness that amorphous crystallizer copper sleeve is increased by adjusting the addition of copper billet solves copper
The even problem of the cooling capacity and inhomogeneous cooling of set；Patent 201310383200.5 discloses a kind of anti-pock amorphous crystallizer,
Bosh is designed as into radial male tank；Patent 201310400924.6 also discloses that a kind of amorphous crystallizer, in copper sheathing
The first tank, the second tank and the 3rd trough shaped radially UNICOM's tank, cooling water enters by water UNICOM's tank, completes right
The circulating cooling of copper sheathing surface molten steel.However, above-mentioned amorphous crystallizer copper sleeve cooling structure is the radial direction type of cooling, it is difficult to from
It is basic to solve the problems, such as that crystallizer axial direction inhomogeneous cooling is even, and have the shortcomings that processing difficulties, design are more according to artificial experience.
The content of the invention
It is big, raw that the task of the present invention is to provide a kind of cooling uniformity and lamination coefficient that can improve molten steel in copper sheathing axial direction
The stable crystallizer copper sleeve cooling structure for preparing amorphous band is produced to solve the deficiencies in the prior art.
The present invention is achieved through the following technical solutions goal of the invention：
A kind of crystallizer copper sleeve cooling structure for preparing amorphous band, it is characterised in that：Including copper sheathing body and
Near the copper sheathing inner body wall arrange bosh, the bosh along copper sheathing body circumference for etc. arc length it is equidistant
Segmented is distributed, and along the axial direction of copper sheathing body also to equidistantly distribute, circumference and axle of each bosh along copper sheathing body
To being respectively equipped with circumferential floor and axial floor.
Further, the axial width of the bosh is 4～6mm, is from copper sheathing inner body wall to the depth of outer wall
10～15mm.
Further, the bosh is circumferentially with 15～30 sections along copper sheathing body, the arc length value of the circumferential floor
For 9～14mm, width of the axial floor along copper sheathing body axial direction is 5～7mm, and the arc length of circumferential floor is worth the excessive shape easily at
The cooling uniformity being unfavorable for into focus in circumference is improved and waste of materials.
Further, width range size of the bosh along copper sheathing body axial direction is less than strip width, and both sides are cold
But tank is 4～7mm with the distance of band both sides.
Further, each section of the bosh is along the circumferential interior cooling water circulation direction all same of copper sheathing, thus, cooling
Water circumferentially flows clockwise or counterclockwise along copper sheathing body, can be prevented effectively from the axial coolant water temperature caused because of axial cooling structure
Rise phenomenon and improve the cooling uniformity of amorphous crystallizer.
Further, the copper sheathing body is made using beryllium copper or chromium-zirconium-copper, due to copper sheathing directly and steel contacts, work
When thermal stress be easily deformed greatly, can make copper sheathing that there is good heat conductivility, high rigidity, wear resistance using both materials
Higher thermal deformation resistant performance.
Further, bosh cross sectional shape vertically is rectangle.
Crystallizer copper sleeve cooling structure provided by the present invention for preparing amorphous band, the bosh in copper sheathing is along copper
The circumference of set body using etc. the distribution of arc length equidistant segmented, and along copper sheathing body axially also to equidistantly distribute, so
Make cooling water in whole bosh be in circumferential movement along copper sheathing, effectively prevent in amorphous band preparation process because of cooling water axle
To the even phenomenon of amorphous crystallizer inhomogeneous cooling that temperature change causes, can to greatest extent stablize amorphous band production technology, carry
High surface quality of strips, and can be used for the amorphous band production of different in width scope, applied range.
