Claims (6)

  1. Formsteuerungseinrichtung zum Einstellen einer Brammenbreite, eines Draufsichtbilds am oberen Ende und eines Brammendickenprofils einer Bramme (10), wobei die Bramme eine Heißbramme ist, die aus einem Heizofen entnommen worden ist, wobei die Formsteuerungseinrichtung aufweist:
    ein horizontales Walzwerk (1) mit horizontalen Walzen (1HR), die sich in einer Dickenrichtung der Bramme an beiden Seiten gegenüberliegen; und
    eine Breitenpreßmaschine (2) mit einem Paar von Breitenpreßformen (2K), die sich in einer Breitenrichtung der Bramme an beiden Seiten gegenüberliegen, wobei
    ein eingangsseitiges horizontales Walzwerk (1) als das horizontale Walzwerk und die Breitpreßmaschine in dieser Reihenfolge in einem Anordnungsintervall (η) angeordet sind, das kürzer ist als eine Brammenlänge (L0) während der Entnahme aus einem Heizofen von einer stromaufwärtigen Seite in einer Brammenförderrichtung,
    dadurch gekennzeichnet, dass das horizontale Walzwerk (1) ausgestaltet ist, um eine Walzgeschwindigkeitssteuerung während der Verringerung der Breite der Bramme durch die Breitenpressmaschine (2) so durchzuführen, dass Walzschlupf nicht auftritt und die Druckkraft auf die Bramme an der Ausgangsseite des horizontalen Walzwerks wirkt.
  2. Formsteuerungseinrichtung für die Heißbramme nach Anspruch 1, ferner aufweisend
    ein ausgangsseitiges horizontales Walzwerk (3) als das horizontale Walzwerk, das nahe einer stromabwärtigen Seite der Breitenpressmaschine angeordnet ist, das ausgangsseitige horizontale Walzwerk ein Paar horizontaler Walzen (3HR) aufweist, wobei
    das eingangsseitige horizontale Walzwerk, die Breitenpressmaschine und das ausgangsseitige horizontale Walzwerk in dieser Reihenfolge von der stromaufwärtigen Seite in der Brammenförderrichtung installiert sind.
  3. Formsteuerungsverfahren für eine Heißbramme unter Verwendung der Formsteuerungseinrichtung für die Heißbramme nach Anspruch 1, wobei das Formsteuerungsverfahren aufweist
    gleichzeitiges Ausführen von Walzen durch das horizontale Walzwerk und Reduzieren einer Breite einer Bramme durch die Breitenpressmaschine an einer Heißbramme, und gekennzeichnet, durch
    Durchführen einer Walzgeschwindigkeitssteuerung während der Verringerung der Breite der Bramme durch die Breitenpressmaschine (2) so, dass Walzschlupf nicht auftritt und die Druckkraft auf die Bramme an der Ausgangsseite des horizontalen Walzwerks wirkt.
  4. Formsteuerungsverfahren für eine Heißbramme unter Verwendung der Formsteuerungseinrichtung für die Heißbramme nach Anspruch 2, wobei das Formsteuerungsverfahren aufweist
    Anwenden einer Druckkraft und einer Zugkraft durch horizontales Walzen unter Verwendung der eingansseitigen und des ausgangsseitigen horizontalen Walzwerks während der Reduzierung der Breite der Bramme an vorderen und hinteren Enden der Bramme und Aufbringen einer Druckkraft durch das eingangsseitige horizontale Walzwerk zu einem Zeitpunkt des Walzenbeginns des ausgangsseitigen horizontalen Walzwerks, wenn die Breite der aus dem Heizofen entnommenen Bramme über die gesamte Länge der Bramme durch die Breitpressmaschine einmal oder zweimal oder mehr verringert wird.
  5. Formsteuerungseinrichtung nach Anspruch 1 oder 2, wobei
    das Anordnungsintervall (η) 0 < η < L0, bevorzugt 0 < η < 0,3 × L0 beträgt, wobei L0 die Brammenlänge während der Entnahme aus dem Heizofen darstellt.
  6. Formsteuerungseinrichtung für eine Heißbramme nach Anspruch 2, wobei
    ein Abstand zwischen den Walzenachsenmitten in dem eingangsseitigen Walzwerk und dem ausgangsseitigen Walzwerk ≤ einer Brammenlänge nach Verringerung der Breite der Bramme.
