Definitions
- the invention relates to a copper mold for the continuous casting of molten steel in the presence of zinc and / or sulfur.
- Zinc as a component e.g. of molten automobile scrap reacts with the hot copper surface and forms in one Diffusion process of brittle ⁇ / ⁇ / ⁇ brass phases. These flake off and run in succession to cracking.
- Sulfur which is present, for example, through casting aids, reacts with copper to large-volume and brittle copper sulfides. These can also flake off. The notch effect resulting from local corrosion is therefore an ideal one Starting point for crack formation.
- the invention is based on the object a copper mold for the continuous casting of molten steel in the presence of zinc and / or sulfur, which have a significantly longer service life has without the heat flow and thus the cooling capacity of the copper mold be influenced in a relevant manner.
- the copper mold is in the most thermally stressed Provide contact area with the molten steel with a diffusion barrier layer.
- Such at least one-layer diffusion barrier layer can according to claim 2 e.g. consist of metals or metalloids, their solubility with zinc and / or sulfur is negligible in the operating temperature range.
- materials include in particular ruthenium (Ru), rhenium (Re), tantalum (Ta), silicon (Si), boron (B), tungsten (W), chromium (Cr) and niobium (Nb). If only zinc Molybdenum (Mo), Titan (Ti), Rhodium (Rh) and Tellurium can also be present (Te) are used.
- the diffusion barrier layer can with the help of a CVD (Chemical Vapor Deposition) or PVD (Physical Vapor Deposition) process directly on a copper surface be applied to a copper mold.
- CVD Chemical Vapor Deposition
- PVD Physical Vapor Deposition
- the diffusion barrier layer on chrome or on other galvanic layers can be applied.
- a diffusion barrier layer can be used as an intermediate layer before application a wear layer, e.g. made of chrome and / or nickel.
- the choice of layer type is determined by two factors. On the one hand, it has to primary objective of a diffusion barrier to be met. On the other hand, the imperative Requirement of good adhesion as an intermediate or top layer.
- chromium oxide As a top layer. Their solubility with zinc and / or with sulfur is in the range of Operating temperatures of a copper mold are negligible.
- the chromium oxide can by a thermal / chemical treatment of a chrome coating, e.g. in a oxidizing atmosphere. This has the advantage that not just the surface itself through an oxide against the diffusion of zinc and / or sulfur in the chrome is protected, but that also the typically existing micro and macro cracks in the chrome coating be closed by the oxide.
- a chrome layer of at least one type of chrome is deposited as a diffusion barrier layer.
- So-called crack-free, micro-cracked and standardized Hard chrome layers can be combined. The combination is carried out in such a way that no cracks are continuous from the layer surface to the base material or become universal in use.
- Layer structure which consists of an intermediate layer of crack-free or micro-cracked Chrome is made and a top layer of standard hard chrome is applied.
- the invention also allows a layer of carbides, nitrides, borides or oxides and their mixed types, for example based on titanium / aluminum (Ti / Al) and chromium (Cr), to be formed as a diffusion barrier layer.
- carbides, nitrides and borides are preferably suitable as intermediate layers.
- Oxides can be used as cover layers.
- the invention sees favorable behavior in particular when using aluminum nitride (AIN), aluminum oxide (Al 2 O 3 ), chromium carbide (CrC), chromium nitride (CrN), titanium carbide (TiC), titanium nitride (TiN), titanium carbon nitride (TiCN), titanium aluminum nitride (TiAIN) and titanium boride (TiB 2 ).
- AIN aluminum nitride
- Al 2 O 3 aluminum oxide
- CrC chromium carbide
- CrN chromium nitride
- TiC titanium carbide
- TiN titanium carbon nitride
- TiCN titanium aluminum nitride
- TiAIN titanium aluminum nitride
- TiB 2 titanium boride
- a diffusion barrier layer can also be formed by applying an aluminum compound, for example aluminum nitrate, to the surface of a copper casting mold, for example a chrome-plated surface. When applied, the surface layer of the casting mold is completely wetted and infiltrated by the salt solution. Annealing at a moderate temperature leads to decomposition to y-aluminum oxide (Al 2 O 3 ) on the entire surface as well as in the micro cracks and open pores. This also prevents the diffusion of zinc and sulfur and thus the formation of brass or sulfur corrosion.
- the aluminum nitrate solution can be applied by dipping, spraying or applying with a brush or roller. The protective effect of the infiltration can be increased by repeated dipping or application.
- Suitable paints, resins or plastics on the surface of a copper mold, e.g. a chrome-plated surface, created a diffusion barrier become.
- Suitable materials are in particular paints, resins or plastics Base of silicone or epoxy.
- the diffusion barrier layer is formed from a ceramic material.
- the Diffusion barrier layer according to claim 5 preferably in the upper half and expediently applied here in the upper quarter or third of the mold length.
- the diffusion barrier layer in a pipe or Plate mold provided in the height area of the bathroom mirror.
- the Diffusion barrier layer applied at a height sufficient to that at oscillation of the bath level, the contact surface is highly stressed overall to cover properly. This range is typically about ⁇ 50 mm or below the bath level or approximately in a range up to approximately 250 mm from the upper edge of the tube or plate mold.
- the area is advantageous between 50 mm and 250 mm, preferably 150 mm to 200 mm from the upper edge away.
- a moving mold (casting roll, casting roll) is according to claim 7 with a diffusion barrier layer, which covers the whole with the Melting steel is in contact with the circumference.
- the diffusion barrier layer according to claim 8 should have a thickness of 0.002 mm to 0.3 mm.
- a preferred thickness of the diffusion barrier layer is according to claim 9 0.005 mm to 0.1 mm is seen.
- a multilayer layer can also be formed. With a multilayer layer several layers and layer materials are combined.
- 1 is a mold plate made of copper.
- the hatched Area 2 illustrates the most thermally stressed Contact area with a molten steel. It has a diffusion barrier layer 3 Mistake.
- the bathroom mirror 4 is indicated in dash-dotted lines.
- the Bathroom mirror 4 can oscillate vertically, so that to cover area 2 Diffusion barrier layer 3 extends about 50 mm above or below the bath level 4. With In other words, the bathroom mirror 4 can also be approximately 150 mm to 200 mm from the top edge 5 of the plate mold 1.
- the diffusion barrier layer 3 consists of a metallic material.
- a tubular mold 6 is indicated in the diagram in FIG.
- Diffusion barrier layer 7 made of a metallic / metalloid. Material illustrates which lies in an area 8 which is approximately 150 mm to 200 mm from the Top 9 of the tubular mold 6 is removed. The height range to the bathroom mirror 10 is about 50 mm.
- FIG. 3 shows in longitudinal section the base material copper 11 of a casting mold 12, such as a plate or tubular mold 1, 6 or a co-rotating mold, not illustrated in more detail, such as a casting roll or casting roll.
- a single-layer diffusion barrier layer 13 made of, for example, aluminum oxide (Al 2 O 3 ) is applied to this base material 11.
- 11 again designates the base material copper of a casting mold 12.
- a multilayer layer 14 is applied to the base material 11, which in the exemplary embodiment consists of a layer 15 of chromium nitride (CrN) brought into contact with the base material 11, a layer 16 of aluminum oxide (Al 2 O 3 ) and a layer 17 as a cover layer made of titanium nitride (TiN ) composed.
- CrN chromium nitride
- Al 2 O 3 aluminum oxide
- TiN titanium nitride
- the base material copper of a casting mold 12 is also 11 designated.
- a single-layer diffusion barrier layer 18 is on the base material 11 made of, for example, aluminum nitride (AIN). It is also a single layer Wear layer 19, for example made of chrome and / or nickel, in Transition area from the base material 11 copper to the diffusion barrier layer 18 provided.
- FIG. 6 again shows the base material 11 copper of a casting mold 12.
- a protective layer 20 made of chromium is applied thereon, which in turn has a diffusion barrier layer 21, for example made of aluminum oxide (Al 2 O 3 ), which runs into the surface of the protective layer 20. is provided.
