Definitions

  • the molten metal may be poured from a ladle into a smaller vessel or series of vessels from which it flows through a metal delivery nozzle located above the nip so as to direct it into the nip between the rolls, so forming a casting pool of molten metal supported on the casting surfaces of the rolls immediately above the nip and extending along the length of the nip.
  • This casting pool is usually confined between side plates or dams held in sliding engagement with end surfaces of the rolls so as to dam the two ends of the casting pool against outflow, although alternative means such as electromagnetic barriers have also been proposed.
  • the ladle is of entirely conventional construction and is supported on a rotating turret (not shown) whence it can be brought into position over the tundish 17 to fill the tundish.
  • the tundish may be fitted with a sliding gate valve 47 actuable by a servo cylinder to allow molten metal to flow from the tundish 17 through the valve 47 and the refractory shroud 48 into the distributor 18.
  • the caster includes a lifting means in the form of four fluid cylinder actuated hoists 71 supported by the machine frame 11 and located to underlie the corner regions of the roll cassette frame 102 when the roll cassette 13 is at the intermediate position - as can best be seen in Figures 2 , 4 and 5 .
  • Actuation of the hoists 71 lifts the roll cassette 13 to the casting position.
  • the upward movement of the roll cassette 13 is limited by inwardly extending flanges 75 on the guide rails 89 which are contacted by outwardly extending flanges 77 on the roll cassette frame 102.
  • the illustrated caster has been advanced by way of example only and it could be modified considerably.
  • the roll supports be mounted on linear bearings for strict linear movement. They could alternatively be supported from the cassette frame on pivot arms to allow arcuate movement providing the necessary lateral movement of the rolls to permit appropriate springing movement. This arrangement would enable further reduction of the effective friction on roll movement.
  • the roll biasing units 51 could be mounted on pivot arms and brought into position for connection with the installed cassette by actuation of hydraulic or pneumatic cylinder units acting on the supporting pivot arms. The precise manner in which the cassette is transported into and out of the casting machine could also be varied.

Claims (4)

  1. Installation pour assurer la coulée en continu de feuillard métallique comprenant une paire de rouleaux de coulée parallèles (16) formant un espacement entre eux ; des moyens de délivrance du métal (46, 17, 18, 19) pour délivrer le métal en fusion dans l'espacement entre les rouleaux afin de constituer un réservoir de coulée (30) de métal en fusion soutenu sur des surfaces de rouleau de coulée immédiatement au-dessus de l'espacement ; des moyens de confinement de réservoir (21) au niveau des extrémités des rouleaux pour éviter tout écoulement sortant des extrémités de l'espacement ; et des moyens d'entraînement de rouleau (128) pour entraîner les rouleaux de coulée dans des sens de rotation opposés afin de produire un feuillard solidifié (20) de métal délivré vers le bas à partir de l'espacement ; cas dans lequel les rouleaux de coulée (16) sont montés sur un module de rouleaux (13) installé dans la machine de coulée, et apte à en être enlevé, en tant qu'unité ; ledit module (13) comprenant un cadre de module (102) et des supports de rouleau (104) aptes à être déplacés sur le cadre de module afin de permettre un mouvement du corps des rouleaux (16) pour les rapprocher ou les éloigner l'un de l'autre dans le but de varier l'espacement entre eux ; caractérisée par des moyens d'arrêt réglables (107) disposés sur le cadre de module (102) sous l'espacement et entre les supports de rouleau (104) afin de servir de butée d'entretoise en vue d'une solidarisation avec les supports de rouleau (104) pour prérégler la largeur minimum de l'espacement entre les rouleaux et réglable en largeur pour varier la largeur minimum de l'espacement et des moyens de sollicitation de rouleau (51) aptes à être exploités lorsque le module (13) est installé pour solliciter les supports de rouleau (104) contre les moyens d'arrêt (107).
  2. Installation selon la revendication 1, caractérisée en outre en ce que les moyens de sollicitation de rouleau (51) sont montés sur la machine de coulée de sorte à pouvoir être raccordés aux supports de rouleau (104) lorsque le module (13) est installé pour solliciter les supports de rouleau (104) vers les moyens d'arrêt réglables (107).
  3. Installation selon la revendication 2, caractérisée en outre en ce que les moyens de sollicitation de rouleau (51) comportent une paire d'unités de sollicitation pour chaque rouleau, chaque unité de sollicitation (51) étant apte à être raccordée au module (13) afin de procurer une sollicitation élastique du rouleau respectif (16) lorsque le module se trouve dans sa position opérationnelle mais pouvant être amovible du module pour permettre au module d'être enlevé de la machine de coulée.
  4. Installation selon la revendication 3, caractérisée en outre en ce que les unités de sollicitation élastiques (51) sont soutenues sur des montures aptes à être déplacées sur la machine de coulée pour qu'elles puissent être déplacées pour se mettre en solidarisation opérationnelle réciproque avec le module, et se mettre hors de cette solidarisation.
