Definitions
- the invention relates to a method for the continuous casting of thin metal strips in a continuous caster with an oscillating water-cooled mold, one vertical strand guide arranged below with devices for support and cooling the strand until it solidifies, one or more Driver roller pairs, which are used to support and promote the strand against the Extruded, a device for bending the strand and one Device for bending back the strand.
- Thickness (up to about 80 mm) is the small strand thickness due to the special Shaping the mold plates and / or by squeezing the strand with still liquid core reached.
- Methods and devices for the continuous casting of metal strips are for example known from publications EP 0 625 388 A and EP 0 776 708 A.
- the metal strand is stabilized by several hydraulically adjustable rollers before it solidifies deformed.
- the strand is in one immediately after the mold Area in which the core of the strand is still liquid, under corresponding Control of the contact pressure is defined and deformed.
- EP 0 350 431 A describes a continuous casting process for the production of slabs known with a reduced thickness compared to the cast state, in which the partially solidified slabs are supported in a first section by rollers become. In a subsequent section, roles are summarized into segments and are summarized individually or as a segment against the The slab is pressed and deformed. The bottom of the swamp is in the area of Holding segments held. It is then deformed to a certain dimension in a third section.
- EP 0 603 598 A1 describes a method for producing a steel strip known by casting a strand and then rolling. From one Chill becomes a steel strand at a speed of 2 - 20 m / min in one Subtracted thickness of 40 - 50 m. The steel strand is opened between squeeze rollers less than 30 mm, especially 10 - 25 mm, squeezed together. In a roll stand the steel strand is rolled down to the final dimension of 2 - 25 mm with a Degree of deformation of> 20%, but primarily 30%.
- a continuous caster as can be seen in the company brochure "CSP / Compact Strip Production / The new casting and rolling process for economical strip production" No. W4 + 9/319 / Forma SMS Schloemann-Siemag Aktiengesellschaft / 4000/8/87. typically consists of an oscillating mold, a vertical strand guide arranged underneath with water nozzles for cooling the strand until it solidifies and one or more driven roller pairs for conveying the strand out. In order that the strand can be conveyed out of the casting plant, the driver rollers are pressed against the strand with a certain pressure, which prevents them from slipping.
- a special feature of these continuous casting machines is the arrangement of the driver rollers for conveying the strand below the solidification point, the absence of the liquid core in the strand ensuring that the strand does not give in to the driver roller pressure and a sufficiently large tensile force is generated on the strand.
- the state of the art here is to press the drive rollers onto the strand with hydraulic cylinders, the pressure being unchangeable during the casting process. This solution has also proven itself when casting low-carbon and austenitic stainless steels.
- the roll pressure required to generate the discharge force leads to a reduction in the thickness of the strand.
- the required contact pressure of the driver rollers is set much higher in practice than would actually be sufficient to exclude with certainty the risk of the driver rollers slipping, which means that the strand gets stuck.
- the strand is rolled in an uncontrolled manner by the driver rollers, with thickness reductions of, for example, up to 8 mm at 60 mm strand thickness.
- the required discharge force can then be increased by increasing the number of roller pairs, by increasing the roll diameter and by driving everyone Roles can be achieved.
- the task set is procedural with the measures of the labeling part of claim 1 in a method for continuous casting of thin Metal strips in a continuous caster with an oscillating, water-cooled Mold and a vertical strand guide arranged underneath solved that for the defined thickness reduction of the strand of at least 2%, based on the strand thickness at the time the strand solidified, and at least to keep a predetermined set strand thickness constant two pairs of driver rollers continuously during the entire casting process a pressure against the strand immediately after it has solidified be pressed being connected by a hydraulic pump Measuring and control device, in which the generated current as manipulated variables Flow strand thicknesses continuously and with the preset target strand thickness be compared to that of the hydraulic pump over hydraulic Piston cylinder units generated variable contact pressure of at least two driver roller pairs is continuously regulated "online”.
- this rolling is carried out in a controlled manner with a total strand thickness reduction, which is at least 2%.
- the thickness reduction is at least 2% so large that the driven rollers cannot slip and it can be so large that the benefits of an increased Strand thickness in the area of the mold and the secondary cooling come into their own.
- This controlled reduction in the thickness of the strand while keeping it constant a preset target strand thickness by at least two Driver roller pairs is achieved according to the invention in that at least a pair of driver rollers that convey the strand with a changeable defined one Continuous pressure against the strand immediately after it has solidified is pressed.
- the current roller spacing corresponds to the strand thickness, recorded by measurement and in a measuring and control device with the preset target strand thickness compared.
- a hydraulic Pump which is connected to the measuring and control device, the Contact pressure, with which the driver roller pair is pressed against the strand, "Online" regulated so that the specified target strand thickness is always obtained and is preserved.
- the strand conveying driver roller pairs with a changeable contact pressure against portable stops pressed.
- the portable stops are placed in corresponding positions brought so that there is a constant roller distance corresponding to the Target strand thickness results.
- the pressure against the stops is there at least so large that the roller spacing in normal casting operation remains unchanged and it is guaranteed that when going through the Cold strand or in the event of casting malfunctions, the pairs of rollers can open.
- a continuous caster according to the invention consists of a strand guide arranged vertically below an oscillating mold with devices for supporting and cooling and, if necessary, for squeezing the strand until it solidifies, at least one pair of driver rollers which are pressed against the strand for supporting and conveying the strand, a device for bending the strand and a device for bending back the strand.
- At least one pair of driver rollers is connected directly below the solidification point of the strand with means for generating a variable contact pressure.
- These means which can be piston-cylinder units fed by a hydraulic pump, are connected to a measuring and regulating device.
- the measuring and control device continuously measures the current strand thickness between the pair of driver rollers via a measuring sensor, for example an inductive displacement sensor, compares this measured value with a previously set target value and regulates "online" the deviations from this target value of the contact pressure to be applied by the corresponding piston-cylinder unit.
- continuous casting system are at arranged at least one pair of driver rollers, portable stops, against which the pressing means, for example piston cylinder units, with changeable contact pressure.
- the portable Stops are designed so that a pre-set roller distance can not be fallen below while exceeding the desired Roller distance is prevented by the contact pressure, and only at Running through the cold strand and possible in the event of casting problems.
- the part of a continuous casting installation (1) shown in FIG. 1 consists of an oscillating mold (2) from which the casting strand (7) with a thickness ( ) exit.
- the vertical strand guide (3) with devices for supporting and cooling and, if necessary, for squeezing the strand (7) to the thickness (d2) -
- the initially liquid casting strand (7) solidifies on its way downward by forced cooling in the area of the vertical strand guide (3) from the outside in, the liquid core (6) getting smaller and smaller Solidification point (17) solidifies the strand in its entire cross section is. Because of the
- the solidification point (17) of the strand temperature which is still very high, is the strand (7) but still very soft, so that controlled rolling in this strand area of the strand with the driver roller pairs (4, 5) according to the invention can be applied.
- driver roller pairs (4, 5) are arranged one below the other in the exemplary embodiment in FIG. 1 directly below the solidification point (17). These two pairs of driver rollers (4, 5) not only support the strand (7) and convey it further downwards, but also roll it in a controlled manner. The rolling takes place starting from the starting strand thickness (d2), first through the driver roller pair (4) with the contact pressure (p 1 ) to the strand thickness (d3) and then through the next driver roller pair (5) with the contact pressure (P2) to the strand thickness ( d4), which should correspond to the desired target strand thickness (d target).
- the strand thickness reduction achieved in this controlled rolling should be at least 2%, based on the starting strand thickness (d2) - in order to meet the two requirements for a minimum strand thickness reduction and keeping the strand thickness constant (d4) to the desired strand thickness (d soll ), the strand thicknesses will be (d3) and (d4) "online” continuously measured during the entire casting process and adjusted accordingly in the event of deviations. This is done as follows:
- one driver roller of the driver roller pairs (4, 5) is pressed against the strand (7) with a piston rod (21, 22) of a piston-cylinder unit (11, 12) with the pressure (P1, P2), while the respective opposite driver roller is attached to one Construction part (18) supports.
- the position of the piston rods (21, 22), which represent a measure of the distance between the two drive rollers from each other for a pair of drive rollers (4, 5), is determined by a suitable one Measured value detectors (19, 20) - for example an inductive displacement sensor - are represented as an electrical signal (d3 ', d4') and this signal (d3 ', d4') is continuously fed into a measuring and control device (10).
- FIG 2 a further embodiment of the invention is shown, wherein the driver roller pairs (4, 5) of the continuous casting system (1 ') are also pressed in this example by a piston-cylinder unit (13, 14) against the solidified strand (7), but with the difference is that the contact pressure (P3) also acts against movable stops (15) via projections (16) arranged on the piston rods (23, 24) of the piston-cylinder units (13, 14).
- the drive roller gap widths (d3, d4) specified by the stops can therefore no longer be fallen short of, since this prevents the stops (15).
- Exceeding the predetermined driver roller gap widths (d3, d4) is prevented in a simple manner by selecting the pressure (P3) higher than is necessary for the conveyance of the strand.
- This increased pressure (P3) which is so high that the driving roller gap widths (d3, d4) remain unchanged in normal casting operation, does not lead to an uncontrolled rolling of the strand - as in known continuous casting plants - but it acts because it directed against a fixed stop (15), no further negative. Since, on the other hand, the pressure (P3) should not be excessively high, so that the driver rollers (4, 5) can move apart at any time, for example in the event of casting operation malfunctions, the pressure (P3) can also be adjusted variably via the pump (9). In order to be able to roll different strand thicknesses in the same continuous casting installation (1 ') in a controlled manner, the stops (15) are designed to be movable in order to be able to set any desired drive roller gap width in this way.

Description
Stand der Technik ist es hierbei, die Treiberrollen mit hydraulischen Zylindern an den Strang zu pressen, wobei der Druck während des Gießvorgangs unveränderlich ist. Diese Lösung hat sich beim Vergießen von niedriggekohlten und austenitischen nichtrostenden Stählen auch bewährt. Beim Vergießen von Stählen dagegen, welche bei Temperaturen von 1100°C sehr weich sind, wie beispielsweise Si-legierte Stähle, nichtrostende ferritische Stähle, hochkohlenstoffhaltige Stähle, führt der für die Erzeugung der Ausförderkraft notwendige Rollendruck allerdings zu einer Dickenreduzierung des Stranges. Hinzu kommt, dass der erforderliche Anstelldruck der Treiberrollen in der Praxis wesentlich höher eingestellt ist als eigentlich ausreichend wäre, um das Risiko des Durchrutschens der Treiberrollen, gleichbedeutend dem Steckenbleiben des Stranges, mit Sicherheit auszuschließen. Durch diesen erhöhten Druck wird der Strang durch die Treiberrollen unkontrolliert regelrecht gewalzt mit Dickenabnahmen von beispielsweise bis zu 8 mm bei 60 mm Strangdicke.
- Aufreißen der Kanten des Stranges
- unregelmäßige Dickenabnahme des Stranges
- Schwierigkeiten bei der Synchronisierung der Motorantriebe der Stranggießanlage wegen der unbekannten Längenänderung des Stranges
- Schwierigkeiten, das vorgegebene Coilgewicht einzuhalten.
Eine Stranggießanlage gemäß der Erfindung besteht aus einer unterhalb einer oszillierenden Kokille senkrecht angeordneten Strangführung mit Einrichtungen zum Stützen und Abkühlen und gegebenenfalls zum Quetschen des Stranges bis zu seiner Durcherstarrung, mindestens einem Treiberrollenpaar, das zur Stützung und zur Förderung des Stranges gegen den Strang gepreßt wird, einer Vorrichtung zum Biegen des Stranges und eine Vorrichtung zum Rückbiegen des Stranges. Mindestens ein Treiberrollenpaar ist dabei unmittelbar unterhalb des Durcherstarrungspunktes des Stranges mit Mitteln zur Erzeugung eines veränderlichen Anpressdruckes verbunden. Diese Mittel, die von einer hydraulischen Pumpe gespeiste Kolbenzylindereinheiten sein können, sind mit einer Mess- und Regelvorrichtung verbunden. Die Mess- und Regelvorrichtung mißt kontinuierlich über einen Messfühler, beispielsweise einen induktiven Wegaufnehmer, die aktuelle Strangdicke zwischen dem Treiberrollenpaar, vergleicht diesen Meßwert mit einem vorab eingestellten Sollwert und regelt "online" bei Abweichungen von diesem Sollwert den von der entsprechenden Kolbenzylindereinheit aufzubringenden Anpressdruck.

- ein Fließschema eines Teils einer Stranggießanlage mit "online"-Regelung des Treiberrollenanpressdrucks,
- Fig. 2
- ein Fließschema eines Teils einer Stranggießanlage mit zwei fest angestellten Treiberrollenpaaren.
Messwerterfasser (19, 20) - beispielsweise einem induktiven Wegaufnehmer - als ein elektrisches Signal (d3', d4') dargestellt und dieses Signal (d3', d4') in eine Mess- und Regelvorrichtung (10) kontinuierlich eingespeist. In diese Messund Regelvorrichtung (10) werden sämtliche Messdaten der am kontrollierten Walzen beteiligten Treiberrollenpaare (4, 5) eingegeben und die Gesamtdickenreduzierung des Stranges (7) mit der vorgegebenen Sollstrangdicke (dsoll) verglichen. Als Ergebnis dieses Vergleichs regelt die Mess- und Regelvorrichtung (10) über entsprechende Steuersignale, die in die hydraulische Pumpe (9) einfließen, den erforderlichen, möglicherweise unterschiedlichen Anpressdruck (P1, P2), für die Kolbenzylindereinheiten (11/12) der Treiberrollenpaare (4, 5). Somit wird jede geringe Veränderung der Treiberrollenspaltweite Über die Kolbenzylindereinheiten (11, 12) und deren Messwerterfasser (19, 20) sofort von der Mess- und Regelvorrichtung (10) erfaßt und von dieser kontinuierlich in eine entsprechende Änderung des Anpressdrucks (P1, P2) für die in Frage kommenden Treiberrollenpaare (4, 5) umgesetzt.
Ein überschreiten der vorgegebenen Treiberrollenspaltweiten (d3, d4), wird in einfacher Weise dadurch verhindert, dass der Druck (P3) höher gewählt ist, als für die Ausförderung des Stranges erforderlich ist. Dieser erhöhte Druck (P3), der so hoch ist, dass im normalen Gießbetrieb die Treiberrollenspaltweiten (d3, d4) unverändert bleiben, führt nun aber nicht - wie bei bekannten Stranggießanlagen - zu einem unkontrollierten Walzen des Stranges, sondern er wirkt sich, da er gegen einen festen Anschlag (15) gerichtet ist, nicht weiter negativ aus. Da der Druck (P3) andererseits nicht übermäßig hoch sein soll, damit jederzeit, beispielsweise bei Störungen des Gießbetriebes die Treiberrollen (4, 5) auseinanderfahren können, ist der Druck (P3) gleichfalls veränderbar über die Pumpe (9) einstellbar. Um unterschiedliche Strangdicken in der gleichen Stranggießanlage (1') kontrolliert walzen zu können, sind die Anschläge (15) ortsveränderlich ausgebildet, um auf diese Weise jede gewünschte Treiberrollenspaltweite einstellen zu können.
