Abstract
The utility model discloses a kind of chill roll roller shell for the preparation of amorphous/nanocrystalline band.This roller shell is double-decker, and the outer surface of internal layer roller shell is attached at the inner surface of outer roller shell, and wherein, the material of internal layer roller shell is brass, and the material of described outer roller shell is beryllium copper or chromium zirconium copper.Composite construction roller shell disclosed in the utility model, compared to individual layer beryllium copper or chromium zirconium copper roller shell, under the prerequisite of effect prepared by guarantee amorphous/nanocrystalline band, reduces the material cost of roller shell significantly.
Description
Technical field
The utility model relates to a kind of amorphous/nanocrystalline band preparation field, particularly a kind of chill roll roller shell for the preparation of amorphous/nanocrystalline band.
Background technology
Amorphous/nanocrystalline band adopts the preparation of planar flow Cast Strip Technique and Its, detailed process is: the chill roll circumferential surface that the high temperature alloy liquation of melting has the nozzle of slit to cast in High Rotation Speed by, need the cooling velocity of 1,000,000 degree/second, being taken away by heat in very short time makes alloy solution be rapidly solidificated into band, the atomic structure of guarantee alloy is amorphous state, band is stripped, capture and batch, and finally obtains the amorphous/nanocrystalline roll coil of strip.For meeting the requirement of cooling fast in preparation technology, usually adopt the copper alloy chill roll roller shell that thermal conductivity is higher.
The chill roll copper sheathing material be applied at present in amorphous, nanocrystalline strip production mainly contains chromium zirconium copper and beryllium copper.
In amorphous/nanocrystalline band process, foundry alloy liquation can produce roller shell and corrode oxidation, all needs turning reconditioning again, to improve roller shell surface smoothness and case hardness after often using a period of time.When roller shell thickness is thinned to the 70%-80% of gross thickness, copper sheathing just can not continue to use, and chill roll roller shell all adopts single layer structure, and remaining copper alloy thickness accounts for the 70-80% of gross thickness, is but difficult to be fully used, thus adds production cost.
Summary of the invention
For the defect of prior art, the purpose of this utility model is to provide a kind of chill roll roller shell for the preparation of amorphous/nanocrystalline band.
To achieve these goals, the utility model takes following technical scheme:
A kind of chill roll roller shell for the preparation of amorphous/nanocrystalline band, described roller shell is double-decker, the outer surface of internal layer roller shell is attached at the inner surface of outer roller shell, described internal layer roller shell is provided with cooling water channel, wherein, the material of internal layer roller shell is brass, and the material of described outer roller shell is beryllium copper or chromium zirconium copper.
The thickness of described outer roller shell is 10 ~ 60mm, and the thickness of described internal layer roller shell is 10 ~ 60mm; The external diameter of described double-deck roller shell is 400 ~ 2500mm, and the width of described double-deck roller shell is 200 ~ 600mm.
Compared with prior art, the utility model has following Advantageous Effects:
Double-decker roller shell described in the utility model, internal layer roller shell adopts brass to be prepared from, and the existing beryllium copper of outer employing or chromium zirconium copper, brass price is lower, effectively reduces the cost of roller shell.In a word, compared to individual layer beryllium copper or chromium zirconium copper roller shell, double-decker roller shell described in the utility model, under the prerequisite of effect prepared by guarantee amorphous/nanocrystalline band, reduces the material cost of roller shell significantly.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model double-decker roller shell, in figure, and 1, outer roller shell, 2, internal layer roller shell.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The chill roll roller shell for the preparation of amorphous/nanocrystalline band that the utility model provides, roller shell is double-decker, the outer surface of internal layer roller shell 2 is attached at the inner surface of outer roller shell 1, the inner surface of internal layer roller shell 2 is attached at the chill roll body of roll, and internal layer roller shell 2 is provided with cooling water channel (not shown), wherein, the material of internal layer roller shell 2 is brass, the material of outer roller shell 1 can be existing any material for chill roll roller shell, such as beryllium copper or chromium zirconium copper.The design of cooling water channel is still existing design, is just arranged in internal layer roller shell.
In order to ensure the effect of roller shell when preparing amorphous/nanocrystalline band better, preferably, the thickness of outer roller shell 1 is 10 ~ 60mm, and the thickness of internal layer roller shell 2 is 10 ~ 60mm; The external diameter of double-deck roller shell is 400 ~ 2500mm, and the width (i.e. body of roll axial length) of double-deck roller shell is 200 ~ 600mm.
The preparation method of chill roll roller shell described in the utility model comprises the following steps:
(1) adopt beryllium copper or chromium zirconium copper for outer roller shell;
(2) adopt brass to prepare internal layer roller shell, be provided with cooling water channel in internal layer roller shell, the external diameter of internal layer roller shell is slightly larger than outer roller shell internal diameter;
(3) by outer roller shell expanded by heating, to make described outer roller shell internal diameter be greater than the external diameter of described internal layer roller shell, interior copper sheathing is placed in outer copper sheathing, naturally cool, the outer surface making internal layer roller shell is attached at the composite construction copper sheathing of the inner surface of outer roller shell.
The preparation method of the double-deck roller shell (compound roller shell) of the present invention is described below by embodiment:
Composite roll nested structure prepared by the present embodiment as shown in Figure 1, the outer surface of internal layer roller shell 2 is attached at the inner surface of outer roller shell 1, and the specification of this two-layer compound roller shell is: the thickness of outer roller shell is 35mm, and the thickness of interior roller shell is 25mm, width is 300mm, and whole roller shell external diameter is 1800mm.Concrete preparation method is as follows:
(1) adopt beallon sheet material to prepare the outer roller shell 1 of chill roll, the outer roller shell specification obtained is as table 1.
(2) adopt brass to prepare the internal layer roller shell 2 of chill roll, and process cooling water channel, the specification of internal layer roller shell is as table 1.The external diameter of internal layer roller shell 2 is slightly larger than the internal diameter of outer roller shell 1, and the difference in internal diameters of the external diameter of internal layer roller shell 2 and outer roller shell 1 is not more than 4mm, is not less than 1mm, and the difference of the two is 2mm in the present embodiment.Make its internal diameter then internal layer roller shell 2 is placed in the external diameter being greater than internal layer roller shell 2 internal diameter becomes large outer roller shell 1 because of expanded by heating because expanded by heating becomes large outer roller shell 1 heating, naturally cool, obtain the chill roll copper sheathing of composite construction.
