Definitions
- the invention relates to a method for producing a hollow cylinder Copper or a copper alloy.
- the invention is directed to a Casting roller made of a hollow cylinder.
- the invention is - based on the prior art - the object of a Method for producing a hollow cylinder made of copper or a copper alloy to create, in particular, the production of large-format products in one greater variation with economic effort allows. Furthermore, a can be provided economically to be produced casting roll in large format.
- the layer-wise winding of the tape becomes a hollow cylinder with homogeneous structural properties produced. It is possible, hollow cylinder with different Material properties to manufacture, through different strip materials. For example, reinforcing materials such as steel, glass or carbon fibers be integrated into such a band. That way you can completely new copper composites with higher or with to the respective requirements specifically adapted strength properties are provided.
- the tape at an angle of 90 ° be fed to the longitudinal axis of the carrier body. It can also be two or several bands are wound parallel next to each other. Neighboring bands are then pasted over their band edges. The width and the number of bands determine while the length of the hollow cylinder to be produced.
- Another winding method provide the features of claim 3. After that the band is deviating in a 90 ° to the longitudinal axis of the carrier body Supplied angle. This is done oscillating over the entire length of the produced Hollow cylinder, in layers from the one end of the carrier body to the other.
- the heating at least the outer layer of the winding serves to better connect the individual layers with each other.
- the heating up can be performed, for example, inductively.
- the joining of the layers can be done in different ways. According to claim 7, the layers are joined by pressing. This is done under high pressure. In particular, the so-called hot isostatic pressing (“Hippen”) applied become.
- Hippen hot isostatic pressing
- a welding according to claim 8 is conceivable.
- the Layers are joined by brazing.
- Requirements for a perfect brazing are oxide-free surfaces, a protective gas atmosphere, but no Inert gas may be wrapped with, or the use of vacuum.
- the tape to form a V-shaped Winding gap obliquely from above the horizontally oriented carrier body is fed, wherein in the winding nip high phosphorus-containing liquid solder with deoxidizing effect in a protective gas atmosphere or under vacuum ready and at least the outer winding layer of the winding body to soldering temperature is held.
- this method is constantly in the winding nip Lotpool, whereby all resulting gaps between the layers with Lot filled. If at least the outer winding layer is heated, can constantly solder to a sufficient extent during the winding as a melt be provided in the winding nip.
- the soldering takes place under Vacuum.
- the temperature in the soldering gap should be approximately equal to the temperature of the solder plus 50 ° C.
- the features of claim 11 are then preferably used, if at least two bands at an angle of 90 ° to the longitudinal axis of the carrier body be supplied. Depending on the width of the bands can then the finished wound hollow cylinders are coaxially joined together. Suitable for this purpose in particular, electron beam welding or friction stir welding, because of the wound hollow cylinder usually precipitation hardened materials for Get used. Their properties are then not or only slightly negatively influenced.
- Vorrohr be made for a mold tube. Also could by the winding process Vorrohr be created with graduated material properties, if different Materials are used. These can then both longitudinally the hollow cylinder can be used as well as in the radial direction.
- the skirting boards can be fastened in different variants. Is advantageous e.g. soldering, welding or hot isostatic pressing. Also a shrinking is conceivable.
- the material of the skirting can match the same as the band be. However, it is also possible to choose a different material type. It is advantageous, e.g. a choice of material with particularly favorable wear properties.
- the thermal conductivity should be as similar as possible to the material of the tape.
- the features of claim 14 allow a finished wound hollow cylinder thereby reshaping into a plate that the hollow cylinder in a its longitudinal axis cutting plane and then bent flat. In connection This plate can be further transformed into a mold plate.
- the entire circumferential casting surface the casting roll is coated.
- the coatability of the edge strips as a criterion.
- the coating of the surfaces can be galvanic respectively.
- the application of a thermal spray coating is conceivable.
- complete wear sleeves can be applied.
- Casting rolls manufactured by the process according to the invention are in the patent claims 15 and 16 marked.
- 1 denotes a drive which is rotatable by means of a drive (not shown) cylindrical support body made of steel.
- a drive (not shown) cylindrical support body made of steel.
- a band 2 of a copper alloy in several layers 3 wound.
- the winding direction is designated WR.
- the layers are 3 when winding directly flat each other.
- the tape 2 is obliquely from above to form a V-shaped winding nip 4 fed to the horizontally oriented carrier body 1.
- the vacuum is not illustrated in detail.
- At least the outer one Winding layer 3 of the winding body 6 is, in particular inductively, not illustrated in detail Keep the soldering temperature.
- the band 2 can according to Figure 2 at an angle ⁇ of 90 ° to the longitudinal axis 7 of the carrier body 1 are supplied.
- the length L corresponds to that of the wound Hollow cylinder 6 of the width B of the band 2.
- the layers 3 are not shown in detail in both FIG. 2 and FIG.
- Figures 4 and 5 show an embodiment in which two according to the representations of Figures 1 and 2 wound hollow cylinder 6 coaxially to each other are joined.
- the joining of the two end faces 10, 11 of the hollow cylinder 6 is, for example done using the electron beam welding.
- the joint is denoted by 12.
- Figure 5 also shows that to form a casting roll 13, the two together joined hollow cylinder 6 with an increased wear resistance having coating 14 are provided.
- This coating 14 can also be used in Form a wear sleeve to be applied to the two hollow cylinder 6.
- Figures 6 and 7 illustrate an embodiment in which a ready wound hollow cylinder 6 in a longitudinal axis 15 intersecting plane E-E separated and this slotted hollow cylinder 6 then according to the arrows VII has been stretched in a plate 16.
- This plate 16 can then be a mold plate be further transformed.
- FIG. 8 shows a casting machine 17 with two casting rolls 13 in the diagram illustrated. With DR, the directions of rotation of the casting rolls 13 are designated.
- a casting roll 13 is a wound according to Figures 1 and 3, the hollow cylinder 6 along the marginal edges 18 provided with annular edge strips 19 (FIGS 8 and 9).
- FIG. 9 a marginal edge region 20 of a wound one Hollow cylinder 6 turned out rectangular and in this twisted marginal edge area 20 an annular skirt 19 inserted.
- the critical abutment with the numerous expiring band ends is eliminated and achieved an uncritical stress on the front pages.
- the determination of the edge strips 19 can by soldering, welding or through Hot isostatic pressing done. A shrinking is conceivable.
- the casting rolls 13 can in particular by hot isostatic pressing on steel cores 22 be joined. This is schematically illustrated in FIG. 4 in broken lines illustrated.
