Description
Technical field
The invention belongs to amorphous thin ribbon preparation fields, are related to a kind of efficient chill roll suitable for Amorphous Wide Ribbon preparation.
Background technique
Amorphous thin ribbon system is with principle: the alloy solution melted in crucible is ejected by the die gap of crucible bottom
In atwirl cooling roller surface, alloy solution is attached on chill roll by very fast cooled and solidified, is blown band device, makes band
It removes chill roll and forms amorphous thin ribbon.Therefore the cooling capacity of chill roll directly influences the quality and qualification rate of amorphous ribbon.
The chill roll of recirculated water cooling is widely used in amorphous thin ribbon preparation process.Chill roll outer surface is copper band, internal
It is recirculated cooling water.When alloy solution is cast in cooling roller surface by nozzle, because the thermal coefficient of copper is larger, alloy solution
The heat of solidification release is rapidly conducted to the recirculated cooling water in copper roller by copper band, and is taken away by recirculated cooling water.At present most
Common chill roll disengaging aquaporin is divergent shape straight channel, when chill roll rotation, due to the active force by conduit wall, shape
At vortex, cooling water is made to be not easy to be discharged.Meanwhile cooling water goes out the water surface and is not easy inwardly to be discharged by the effect of outside centrifugal force.
Cooling water is passed through from one end of chill roll, by the annular gap water channel contacted with copper band, is flowed out from the other end.This chill roll
Structure is along the temperature distributing disproportionation of chill roll width direction, and due to the heat convection of copper band and cooling water, and at water inlet, temperature is low
At water outlet, the uneven consistency to influence the amorphous characteristic in strip width direction of copper band temperature in the width direction.With
The thermic load of the increase of bandwidth processed, chill roll also rises with it, and the temperature difference at center and both ends is bigger, and Temperature Distribution is inconsistent
Property is more obvious, to influence the consistency of amorphous thin ribbon amorphous characteristic in the width direction.
Summary of the invention
For the deficiency for solving existing structure, the first problem that the present invention solves is that chill roll outer ring temperature is along width side
To problem is unevenly distributed, a kind of novel cooling roll structure that cooling water is discharged into cooling duct from both ends by centre is provided.
It is divergent shape straight channel that second technical problem of present invention solution, which is for existing water entering surface and water outlet surface current road,
This structure centre position width is less than circumference, is easy to generate vortex in circumference, influences the mobility of cooling water.It is of the invention thus
A kind of coolant flow channel of good fluidity is provided.
Present invention solution third technical problem is for existing divergent shape straight channel in chill roll rotation process
Centrifugal force effect, it is advantageous to the flow of cooling water of water entering surface, it is unfavorable for the water flow flowing of the water surface out, and then provide one kind to make
Cooling water can quickly flow out, the high runner of heat exchange efficiency.
In order to solve the above technical problems, its technical solution is as follows: novel cooling roller device integral layout include blanking cover, thoroughly
Lid, water inlet pipe, flow distribution pipe, left and right two cover boards, two inner cores, main shaft, copper band, two outlet pipes, holding screw, bearing, pressures
Lid screw, end ring, dynamic seal ring.
Copper band is realized with threaded hole and left and right cover board by processing inner stopper and positions and couple；Water inlet pipe, flow distribution pipe and master
Axis is realized by screw thread and is sealingly connected；Between the main shaft and left and right inner core, left and right cover board by the dynamic seal ring realize with it is cold
But the sealing between water, prevents cooling water from oozing out；The bearing realizes axially position by installing the end ring on main shaft,
Prevent the axial float in chill roll rotation process；The flow distribution pipe is mounted on the water inlet pipe plane of symmetry, it can be achieved that left and right goes out
Structure, space in aquaporin is identical, to make the pressure of left and right water outlet, flow and flow velocity be consistent, to make to cool down
The cooling effect of roller width direction is consistent；
The left and right inner core is hollow structure, processes runner in both ends of the surface, water entering surface is that the divergent shape with additional ribs is straight
Runner, the water surface is the arcuation runner with additional ribs out, and the water entering surface of inner core is installed face-to-face when installation or so；The main shaft is sky
Mandrel structure, both ends process apopore, radial to process through hole, flow in and out cooling water from inlet opening；It is described two go out
Water pipe is that straight bend pipe is coupled by screw thread with main shaft, is discharged convenient for cooling water.The blanking cover and transparent cover at both ends position spiral shell by seam allowance
Nail couples with main shaft.
Preferably, the main shaft is fixed hollow axis, and cooling water enters cooling water by the middle part of chill roll width direction
Seam, is discharged by both ends, improves the coefficient of heat transfer of chill roll medium position.
Preferably, the chill roll is installed face-to-face by two inner cores with coolant flow channel, and inner core be it is hollow welding and
Cast structure.
Preferably, the chill roll, it is characterised in that water entering surface and the water outlet surface current road respectively straight bulk with additional ribs
With arcuation Y shape channel.
Preferably, the chill roll, it is characterised in that be equipped with flow distribution pipe inside main shaft, keep the structure of intake-outlet complete
Unanimously, make disengaging water flow velocity, pressure consistent.
Beneficial effects of the present invention:
(1) during making band, cooling water enters cooling gap along chill roll widthwise central position, flows out from both ends,
The coefficient of heat transfer highest for making middle position in the width direction keeps chill roll consistent along the cooling efficiency of bandwidth direction, makes to produce
Amorphous thin ribbon consistency is preferable in the width direction.
(2) additional ribs are used in water entering surface and the water surface out, makes to pass in and out water surface channel along the width one of chill roll radial direction
It causes, existing sector channel can be prevented to be vortexed in circumference, so that the flowing for accelerating cooling water updates, improve cooling capacity.
(3) flow passage structure different from exit face using inlet face, cooling water is under the influence of centrifugal force in water inlet surface current
It is fast very fast, using straight channel easy to manufacture.By the effect of centrifugal force, cooling water is not easy inwardly to flow out the water surface out, runner
Using arcuation runner opposite to the direction of rotation, cooling water can quickly be flowed out by the effect of wall surface, while use additional ribs, cold
But water flowing is laminar flow, reduces turbulent flow, to reduce pump work.
