Abstract (en)

[origin: DE19951262C1] Opposite rollers (11, 31; 12, 32) in respective rows of at least one segment are spaced such that, in the unsteady state with bulges of the strand moving at the casting speed, they exhibit a phase shift with respect to a sinusoidal oscillation with wavelength (IR). This phase shift is given by : DELTA phi = ( DELTA I/IR) x 2 pi . Where: MOD( DELTA phi ) = 20 deg -90 deg , DELTA I = variation of the basic roller spacing IR, IR = Actual spacing of two rollers in a row, with Ir = VG/f, VG = casing speed, f = VG/IR = frequency of bulging in cast strand shell encasing liquid metal.

Abstract (de)

Die Erfindung betrifft ein Strangführungsgerüst einer eine stationäre Kokille aufweisenden Stranggießanlage, insbesondere für Dünnbrammen aus Stahl, mit der Strangdicke entsprechenden lichte Weite aufweisenden Reihen von in Segmenten (1,2) mit einer Rollenteilung lR angeordneten Rollen (11-18;21-28) zum Führen und Treiben des mit Flüssigmetall gefüllten Stranges. Die gegenüberliegend angeordneten Rollen (11,31;12,32) der jeweiligen Reihen mindestens eines Segmentes besitzen solche Abstände, daß sie für eine instationäre, sich mit Gießgeschwindigkeit bewegende Ausbauchung des Stranges eine Phasenverschiebung Δϕ gegenüber einer Sinusschwingung mit der Wellenlänge lR aufweisen. Dies entsprechend dem Ansatz: Δϕ = (Δl/lR) x 2π mit | Δϕ |= 20° bis 90°, wobei, Δl = Änderung des Basisrollenabstandes lR, lR = Istabstand zweier Rollen einer Reihe (Rollenteilung) bei lR = v/f, vG = Gießgeschwindigkeit und f = vG/lR = Frequenz des von der Strangschale umhüllten Flüssigmetalls bedeuted. <IMAGE>
