Definitions
- the invention relates to a strip casting installation for metals, especially for aluminum and aluminum alloys, with a slidable in the direction of flow of the liquid metal and vertically adjustable pouring nozzle for feeding of liquid metal in the adjustable roll gap between rotating molds, the pouring nozzle consisting of two nozzle elements articulated to a melt distribution trough and two side delimiters, which are slit-shaped Form the outlet opening for the liquid metal.
- the casting nozzle has horizontal or inclined belt casting systems an upper and a lower, in vertical strip casting systems a left and a right nozzle element. Further concerns the invention is a method for operating the strip caster.
- Known belt casting systems have a first variant two casting rolls arranged one above the other (e.g. Lauener Rollcaster), according to a second variant two on top of each other continuous casting belts (e.g. Hazelett) or caterpillars (e.g. Lauener Block Caster), which from a machine frame be held or arranged in a housing are.
- continuous casting belts e.g. Hazelett
- caterpillars e.g. Lauener Block Caster
- a nozzle between the two casting rolls In the area of the roll or casting gap is in the working position a nozzle between the two casting rolls, which is usually fixed on the machine frame.
- a pouring trough fed by a gutter system from a specialist Called melt distribution trough, conducts liquid metal into the nozzle, the flowing metal solidifies between the casting rollers and emerges as a partially rolled strip.
- This pouring nozzle can be turned on and off together with its nozzle holder be expanded, but accessibility is, in particular severely hampered by machine frame or housing.
- tapes are made down to the strip casting process a thickness of about 2 mm, in particular 3 to 7 mm, cast, something very high about the nozzle itself and its positioning Demands.
- the nozzle must not only prevent erosion or dissolution in aggressive, Resist liquid metal, it must not have high thermal conductivity, because otherwise the liquid Metal could solidify in the nozzle and has to roughen it Resist foundry.
- a 2752649 has long been a more suitable one Material known for a pouring nozzle. This must be so be positioned exactly so that on the one hand there is an unwanted Parts do not damage the roller surfaces, but on the other hand, not so between the nozzle and the casting roller large gaps are formed that the liquid Do not put metal between the nozzle and the surface of the casting roller can penetrate.
- For casting aluminum for example is a distance of the nozzle to the casting roll of 0.2 mm considered optimal, penetration above 0.5 mm can hardly be prevented by molten metal.
- A1 0443204 is a horizontally displaceable and Height-adjustable pouring nozzle for feeding liquid Known metal in a roll gap, in which the metal feed not interrupted while positioning a nozzle must become. This allows the pouring nozzle to be replaced without downtime.
- EP, A1 0137238 describes a casting system for continuous Strip casting of metals, especially a nozzle arrangement with an extruded nozzle holder and one fireproof, pre-cast nozzle.
- the nozzle holder is as one Extruded and shows all essential details and Tolerances.
- This nozzle holder and an additional fastening wedge consist of an extruded aluminum alloy.
- the pouring nozzle is attached to the holder with screws attached and for example with a fastening wedge clamped. This will remove and replace the Nozzle done in minimal time.
- JP, A 01224144 has a slow and steady Flow of molten steel to the object, hence a Cast strand of good quality can be made.
- the molten metal introduced from a distribution trough directed into the interior of the fixed nozzle element. After Decreasing the flow rate occurs the melted Metal out of the nozzle gap 11.
- a movable nozzle element can with an actuator towards the fixed nozzle element or be moved away from it. That can the nozzle opening between the nozzle elements and thus the Flow rate of the molten steel set will. With this vertical continuous casting process Cast bars of good quality are made.
- the inventors set themselves the task of a strip caster for metals of the type mentioned and a Process for their operation to create a pouring nozzle allow with always optimal positioning.
- the object is achieved according to the invention in relation to the strip caster solved by one or both of the nozzle elements adjustable at least in the area of the outlet opening is.
- Special and further training embodiments the strip caster are subject to dependent device claims.
- Adjustable nozzle elements cause a retreat the gap between the nozzle lip and the roller is constant held and no metal can flow back.
- the two side delimiters of the pouring nozzle are known per se Way designed so that the outlet opening the nozzle can expand when retracting without metal between flow out of a nozzle element and a side limiter can.
- a joint located directly on the melt distribution trough is preferably a hinge pivotable about an axis.
- a joint on a nozzle element is expediently one by one Axis swiveling hinge, a foil hinge, at Casting aluminum, especially spring steel, a molded one elastic block, especially from the same Fiber material such as the nozzle element, or a tensile fabric.
- the nozzle elements can be built in a conventional manner viewed from the side essentially in the form of a Pen. At least one nozzle element is more suitable Site severed to form a joint and articulated with the remnant rigidly hinged to the melt distribution trough connected.
- the invention can also be used to design to simplify the pouring nozzles.
- a plate-shaped Piece is rigidly connected to the melt distribution trough and has an articulated connection in the direction of the outlet opening to a much thinner plate, which in Cross-section long rectangular, but corresponding to rombus or can even be almost triangular.
- the very small distance is about 0.2 up to 0.5 mm of a nozzle lip to the corresponding roller constant to keep that neither scrap marks on the casting rolls still flowing through metal between the pouring nozzle and Casting roller can occur.
- nozzle lips Sliding inserts made of a self-lubricating material, in particular made of graphite or hexagonal boron nitride, built into the nozzle elements. This allows the nozzle elements regularly in exposed areas or across the entire width spread out without any Grinding marks arise. For more information, see the DE, A1 2131435.
- the sliding insert can also extend over the entire width of the nozzle.
- the existing, albeit slight metallostatic pressure towards an expansion of the outlet opening Preferably becomes horizontal or sloping during the retreat Pouring nozzle the metallostatic pressure increases, in particular by increasing the level in the melt distribution trough. In order to ensures that the moving part of the nozzle elements spread or shifted in parallel until the original distance from the casting rolls restored is.
- the pivoting movement or the parallel displacement at least a nozzle element can also with the help or at least under Use mechanical force.
- the Drive can be by spring force, by a counterweight, by pneumatically, hydraulically or electrically generated force respectively.
- the use of the casting nozzles according to the invention can, as at the beginning indicated, in all types of strip casting systems, for example Roll casting systems, casting systems with endless revolving Belts or caterpillar tracks are made.
- the cast metal band always has a level line-free Surface, so no transverse channels.
- Ceramic fibers used, which are impregnated with a slip, dried and burned. This creates a relatively brittle molded body which is fireproof, resists the liquid metal chemically and physically and has low thermal conductivity.
- the pouring nozzle 10 shown in FIG. 1, which is articulated to a melt distribution trough 12 (not shown) (FIG. 3), comprises an upper and a lower nozzle element 14, 16.
- the upper nozzle element 14 has an adjustable mouthpiece 18 and is parallel to one another Outlet opening 20 of the pouring nozzle 10 pivotable axis A 2 of a hinge 22 pivotable.
- the pouring nozzle 10 When starting, the pouring nozzle 10 is with the outlet opening 20 advanced to the starting position S shown in broken lines.
- the distance of the nozzle lips 24 from the top and the lower casting roll 26, 28 is in the range from 0.2 to 0.3 mm.
- the distance d of the nozzle opening 20 from the roll gap 30, the smallest distance between the casting rollers 26, 28 on the connecting plane E of which are outside the drawing sheet Axes, is in the range of 20 to 50 mm.
- the pouring nozzle 10 is around the Distance a from about 30 to 70 mm in the working position W der Exit opening 20 withdrawn.
- the Pouring nozzle 10 also program-controlled, to the depth t lowered, taking into account the not shown Roller radius and the distances a, d is calculated so that the distance of the nozzle lip 24 of the lower nozzle element 16 from the lower nozzle roll 28 unchanged at about 0.2 to 0.5 mm remains.
- the mouthpiece 18 of the upper nozzle element is included in the following Figures set means shown in detail so that the same distance of the nozzle lip 24 from the top Nozzle element 16 is retained.
- the pouring nozzle 10 thus adapts automatically when moving back to the roller and leaves relatively large adjustment options to.
- the distance d is set as small as it allows the construction of the nozzle, the distance a is so large that the machine is not overloaded or dimensioned larger have to be.
- the lower nozzle element 16 also has a mouthpiece 18 which can be pivoted via a hinge 22 with an axis A 2.
- the pouring nozzle 10 is retracted from the starting position S into the working position W by the distance a the height of which is not adjusted, the lowering t of FIG. 1 is omitted.
- Both mouthpieces 18 are adjusted by means of pivoting about the axes A 2, which will be described in detail later, in such a way that the distance between the nozzle lips 24 and the casting rolls 26, 28 remains unchanged at approximately 0.2 to 0.3 mm.

- Both nozzle elements 14, 16 are supported by a pivotable or rigid nozzle holder 34, 36, which can be removed with the pouring nozzle 10, a lowerable slide 38 closing the melt distribution trough 12.
- the melt distribution trough 12 is through a partition 40 separated from the mobile launder 32 with an opening 42.
- This opening 42 is connected by means of a flap 44 a terminal, truncated cone-shaped pin 46 is program-controlled lockable.
- the pivoting movement of the flap 44 is indicated by an arrow 48.
- the metal level 50 in Melt distribution trough 12 is due to the immersion depth of the Pin 46 adjustable in the opening 40, but it lies in any case below the metal level 52 in the mobile Watering channel 32.
- Both the mobile trough 32 and the melt distribution trough 28 are with a refractory insulation layer 54 lined.
- the metal level 52 of the mobile launder 32 and the metal level 50 of the melt distribution trough 12 are, for the sake of simplicity not shown floats or non-contact working sensors checked and adjusted. Both methods are known per se.
- the generated signals are proportional to the height of the swimmer or the distance between sensor and metal surface. These signals are refurbished and become a processor or computer transmitted where the actuation of actuators is triggered which is the metal supply according to the measured Control metal levels 50, 52.
- actuator is for example the flap 44.
- FIG. 4 shows a variant of an upper nozzle element 14 shown with an adjustable mouthpiece 18.
