Definitions

  • the minimum intake speed at the inlet of the rolling train should under no circumstances be less than 4.2 m / min in order not to thermally overload the rollers due to the long contact time with the rolling stock.
  • the billet at the inlet of the mill train should have a suitable temperature for rolling both at the surface and in the core (1150-1250 ° C).
  • the surface temperature should be distributed as homogeneously as possible.
  • the present invention has for its object to propose a method that allows a simpler plant configuration and a more cost-effective operation.
  • the process for the production of steel long products in which the billets and blooms produced in the continuous casting mold are fed directly - without additional heating - a rolling train and rolled there to long products, allows a simple system configuration and a cost-effective operation.
  • a sliding closure 15 is provided for the purpose of accurate inflow control of the molten steel to be poured into the mold.
  • a regulation of the fill level of the melt in the mold 3 is carried out as a function of the inlet speed in the first stand (so-called master-slave operation), for a control device 13 and a level gauge 14 are provided in the mold 3. This regulation is intended to achieve an approximately constant filling level in the mold.
  • a refractory dip tube attached to the inflow control element and protruding into the mold is advantageous, so that the bath surface in the mold is as smooth as possible.

  1. Procédé de production de produits longs en acier par coulée continue d'acier en des barres de billette et laminage ensuite de ces barres de billette et de ces barres de bloom en produits longs, comme de l'acier en barre ou du fil, l'acier liquide étant versé dans une lingotière de coulée continue dans lequel la lingotière de coulée continue, d'un format carré ou rectangulaire à sommets arrondis de grand rayon ou d'un format sensiblement circulaire, forme une empreinte de moulage ouverte des deux côtés qui, à l'extrémité du côté d'entrée, a le long d'une ligne de pourtour de sa section transversale au moins deux parties de pourtour qui délimitent, sous la forme de courbure, respectivement un agrandissement de la section transversale de l'empreinte par rapport aux parties de pourtour correspondantes de la section transversale de l'empreinte à l'extrémité du côté de la sortie de la barre de la lingotière et les hauteurs d'arc des courbures se rapetissent dans la direction de passage de la barre de manière à ce que, pendant la coulée, une coquille de coulée se formant dans l'empreinte se déforme lorsqu'elle passe dans la lingotière, les barres coulées de billette ou de bloom étant envoyées directement à un train de laminoir sans post-chauffage et la vitesse de coulée continue étant au moins de 4,2m/min, dans lequel, dans la busette (11) de coulée d'un récipient (2) intermédiaire se trouvant au-dessus de la lingotière (3) il y a un organe de régulation, de préférence une fermeture (15) à tiroir, en vue d'une régulation précise de l'acier fondu à couler dans la lingotière, une régulation de la hauteur du niveau de la masse fondue dans la lingotière 3 s'effectuant en fonction de la vitesse d'entrée dans la première cage de laminoir du train (20) de laminoir et l'organe de régulation étant régulé d'une manière correspondante.
  2. Procédé selon la revendication 1, caractérisé en ce que les barres de billette coulées forment sensiblement un format carré ou rectangulaire à sommets arrondis de grand rayon.
  3. Procédé selon la revendication 2, caractérisé en ce qu'on choisit l'arrondi dans le format carré ou rectangulaire à sommets arrondis de grand rayon conformément au format de manière à produire, pour une vitesse de coulée suffisamment grande, une barre ayant une répartition de température nécessaire pour le laminage qui, sans quelque post-chauffage actif que ce soit, peut être laminée directement.
  4. Procédé selon la revendication 1, caractérisé en ce que les barres de billette coulées sont sensiblement circulaires.
