Definitions
- the invention relates to a casting roller for casting strips of aluminum or Aluminum alloys.
- the invention is based on the object To take measures with which the crack formation on a casting roll at least one copper cladding layer for casting aluminum strips or aluminum alloys can be slowed to the life of the Increase casting roller.
- Diffusion barrier designed as a single-layer protective layer.
- the one to create one Diffusion barrier required effort is therefore limited and impaired the economics of manufacturing and providing a casting roll in one only insignificant scope.
- the Diffusion barrier from a through a high-energy thermal spray process applied metallic, metal-ceramic or ceramic protective layer is formed.
- the thermal spray process can, for example, be plasma or Be laser spraying.
- the metallic, metal-ceramic or ceramic layers can be based in particular on nickel, cobalt and oxides and carbides be formed.
- the diffusion barrier consists of a electroplated chrome layer is formed.
- Such a diffusion barrier only needs to have a thickness of approx. 5 ⁇ m to 20 ⁇ m. Because one repeated Reworking the casting roller in use would be relatively easy on site feasible chrome plating makes sense. Tampon electroplating is ideal for this, if necessary as part of normal reworking in a foundry can be carried out. Large pools for holding a casting roller are not required here.
- the applied Chromium layer can be further improved in its properties by nitriding, because it also closes minimal cracks in the chrome layer can.
- the diffusion barrier instead of a diffusion barrier made of a chrome layer, it is according to the characteristics of claim 5 possible, the diffusion barrier from a galvanic to form an applied layer of nickel or a nickel alloy.
- a solution / suspension with oxide or phosphate-forming Metals such as chrome, zinc, titanium or zirconium, also in combination with aluminum or silicon oxides can be applied. Then such an order advantageously before starting a casting roll by a suitable one thermal treatment converted into the effective protective layer.
- a diffusion barrier can also consist of a through Combustion generated carbon layer can be formed.
- To burn the Carbon layer can, for example, at least one acetylene burner be used.
- a carbon layer can also be formed from an oil / lubrication film.
- the embodiment defined in claim 8 sees a diffusion barrier applied organic paint. After this varnish has dried, one should closed protective layer with a thickness of at least 10 ⁇ m should be present. As upper limit should not be exceeded 60 ⁇ m. Here is one ensure uniform wetting of the cladding layer, but this depends on the viscosity and the subsequent drying of the paint depends.
- a diffusion barrier can also use a PVD / CVD method (Physical or Chemical Vapor Deposition), e.g. on the Base of TiN, CrN or TiAI.
- PVD / CVD method Physical or Chemical Vapor Deposition
- a diffusion barrier made of an inorganic Protective layer formed it is preferably in the range of 0.01 mm to 0.2 mm.
- the thickness of the Diffusion barrier is in the range of 0.05 mm to 0.12 mm. Larger layer thicknesses are disadvantageous, since then under the swelling operating load Casting roller in turn can form cracks that lead to crack propagation in the Lead base material.
- a diffusion barrier expediently a thickness between an inorganic protective layer 5 ⁇ m and 50 ⁇ m. This is particularly the case when the diffusion barrier is considered Carbon layer is deposited from a combustion process. Essential is also a closed, uniform layer. Can be applied also an oil / grease film. Ideally, cracking into one takes place here carbon-containing layer with a typical thickness of approx. 5 ⁇ m to 40 ⁇ m. However, a uniformly dense, less porous layer is preferred in the Target thickness range from 10 ⁇ m to 30 ⁇ m.
- the diffusion barrier with a multi-layer protective layer to form similar layer combinations.
- a multi-layer protective layer e.g. galvanic layers with possibly different properties in the Layers of the protective layer are particularly advantageous.
- the diffusion barrier consists of a multi-layer protective layer with each other deviating layer combinations is formed. It can be for example metallic / metal-ceramic / ceramic base layers on the one hand and top layers on the other hand from a suspension order from a Act carbon layer, etc., whereby the barrier effect against diffusion of aluminum in the copper cladding layer can be specifically increased. Also PVD protective layers on a metallic base layer represent an advantageous one Protective layer.
- Figure 1 in Figure 1 is a casting roll for casting strips of aluminum or Called aluminum alloys. The representation is not to scale.
- This casting roller 1 has a cladding layer 2 made of copper or a copper alloy while the core 3 is made of steel.
- a casting roll 1 is also conceivable with several, at least two, concentric cladding layers.
- the peripheral surface 4 of the cladding layer 2 has a blocking effect against the diffusion of aluminum into the copper edge zone Provide diffusion barrier 5.
- the diffusion barrier 5 is a single-layer protective layer executed.
- the diffusion barrier 5 can be made by a high-energy thermal Metallic, metal-ceramic or ceramic spray applied Protective layer can be formed.
- diffusion barrier 5 made of an electroplated chrome layer conceivable.
- the diffusion barrier 5 can consist of a galvanically applied layer Nickel or a nickel alloy may be formed.
- the diffusion barrier 5 by thermal Treatment of an applied to the surface 4 of the cladding layer 2 Solution / suspension with oxide or phosphate-forming metals is formed.
- the diffusion barrier 5 can also be applied by applying an organic lacquer be educated.
- the diffusion barrier 5 can be made using a PVD / CVD method applied protective layer may be formed.
- the diffusion barrier 5 consists of an inorganic protective layer this a thickness D between 0.01 mm and 0.2 mm, preferably 0.05 mm to 0.12 mm.
- a thickness becomes D between 5 ⁇ m and 50 ⁇ m.
- Figure 2 is a casting roll 1a for casting strips of aluminum or Illustrated aluminum alloys, which also a cladding layer 2 made of copper has on a steel core 3.
- Two layers 6, 7 are illustrated. These layers 6, 7 can be of the same type Layer combinations can be formed.
- the layers 6, 7 are made of different ones Layer combinations are formed.
