- the invention relates to a method for continuously machining a surface cast steel product in the hot state to eliminate surface defects, Surface contaminants and the like.
- the Invention a device for this and a system for the production of tapes and sheets with a surface processing device integrated in the process flow.
- the cast product is not one limited thickness or geometry.
- the surface processing of sheets and strips is made of steel after rolling out in the cold state known for example by pickling.
- RSH rust, acid and heat-resistant
- Qualities creates an outer skin that is geometric on the one hand May have surface defects or markings and, on the other hand, impurities of segregations, oxides and mold powder residues. It is therefore desirable to remove these before rolling in order to meet the highest product requirements the surface properties of the rolled strips and sheets to suffice.
- EP 0 435 897 B1 describes a method for grinding ingots or blocks or similar workpieces made of metal, in which surface defects or Surface contamination can be removed when warm.
- Advantage of this advanced grinding treatment when warm, i.e. in direct connection with casting, continuous casting, rolling or other thermoforming, is that the material is sanded before cooling due to scale can form on the surface, which in addition to the cold Surface defects must be removed.
- There will be a certain temperature interval specified for the use of the grinding process its lowest limit is the temperature at which there are essentially no scale layers form.
- the upper limit is due to the composition of the sanding belt determined, i.e. by the highest temperature at which the tape is not disadvantageous is thermally impaired.
- the present invention has for its object a method and a To create facility with which a surface treatment of continuous encapsulated steel products to eliminate surface defects in the hot Condition when using not necessarily adapted to high temperatures Surface processing equipment achieved with long service life becomes.
- the targeted temperature reduction is here on the surface of the metallic Product limited and advantageously matched so that the machining resistance of the workpiece is not influenced in an undesirable manner.
- all surfaces of the metallic product e.g. a thin slab section, i.e. Top and bottom, as well as the side surfaces, are cooled. But it is also conceivable that only one surface, for example only the top of the metallic Product is cooled, or only defined sections of surfaces.
- the steps the surface cooling and surface processing an inspection at least a part of at least one surface of the metallic product for surface defects precedent or contamination and depending on the inspection result selective surface treatment only of those detected as defective Surface areas follows.
- partial cooling can refer the inspection to all surfaces or only to areas.
- the subordinate partial cooling of the surface is preferably carried out continuously, one is also conceivable limited to the areas detected as defective Cooling with corresponding additional operational expenditure and under the following Consideration of the temperature differences within the surface.
- the Surface processing complex with the step sequence surface inspection, partial Cooling the surfaces as well as surface processing a cleaning, preferably a descaling process immediately preceding.
- a descaling process there is an additional cooling effect, on the other hand, a scale that may have already formed or existing surface contamination becomes eliminated and a suitable basis for the inspection created the surface.
- All known methods for surface processing can be used, such as grinding, milling or flaming.
- Grinding can be used using known tools such as grinding belts, slices or stones with different grain and grain.
- the bottom or top and / or the side surfaces of the cast product for example in the form of a Slab or thin slab to be processed both simultaneously and in succession.
- simultaneous processing the processing time is reduced, and the Energy consumption is kept low, especially since the surface is removed in the warm Condition occurs in which the removal takes less energy than in the cold Condition can be done.
- the surface processing takes place partially cooled surfaces together with the preferably proposed preparatory Process steps for a continuously cast steel product preferably between the casting and the - preferably directly following - rolling process instead of.
- the surface treatment is either inline in this production line (X) integrated or takes place offline in a side line (Y).

The details of the rolling mill (roughing stands, coil box, etc.) and the Cooling facilities and reel system adjoining Walzstrasse 5 not shown. Depending on the design, the separating device can be omitted become.
- the cast slab 2 is after the deflection in the horizontal through the cross-section device 3, preferably in the form of cross-section scissors, in sections divided and conveyed through the furnace 4.
- the in the oven 4 on homogeneous Roll temperature heated or thermally balanced slab sections are then in the illustrated embodiment in the rolling mill 5 rolled into strips. This process is subsequently called the production line (X) designated.
- a device for surface processing 6 in the warm state of the respective slab section there is a device for surface processing 6 in the warm state of the respective slab section arranged.
- the type of surface treatment is not specified here, for example, known methods such as grinding with grinding wheels, -bands or stones or milling.
- the slab transport speed during the surface treatment in about the casting speed.
- a device for partial cooling 7 is arranged before the surface treatment facility 6 is - seen in the conveying direction - .
- both the sub and Top of the respective slab section simultaneously in a defined Part section cooled by means of a two-part cooling device (parts 7a, 7b), for example by means of nozzles that apply a cooling medium to the surface.
- the processing means 6 in addition to a Surface cooling device 7 A surface inspection device 8 upstream.
- This also consists of two components 8a, 8b together to define the top and bottom of the slabs 2 over a defined Section continuously as it passes through and possibly To detect surface defects.
- a selective surface treatment is carried out, for example by the Only attack abrasives locally on the slab surfaces.
- Such an inspection happens with known types of surface analyzers that the Scan the surface like a grid or in sections.
- an embodiment with a descaling device 9 is made two components (9a, 9b) for simultaneous influencing of the top and bottom of the slabs 2 shown. It is also conceivable for the top and bottom or the side surfaces by means of appropriately staggered devices to process one after the other.
