Definitions

  • the technology of continuous casting in which, by cooling a molten metal on the walls of a mold cavity of a continuous casting mold, forms a continuous shell with a continuously increasing thickness and continuously extrudes a strand from an outlet opening of the continuous casting mold, is known to apply to peritectic steels, for example steels with a Carbon content of 0.1-0.14%, to problems that are particularly evident in the poor surface quality of the strands produced. Such quality defects are undesirable, especially since further processing of the strands often leads to unacceptable quality defects in the subsequent products.
  • the heat-insulating layer in the area of the first longitudinal section increases the temperature on the inside of the mold tube. Because the distance of the heat-insulating layer from the inner surface of the mold tube is at least 25% of the wall thickness of the mold tube, the wear of the mold tube during casting operation is due to the thermal and mechanical

Abstract

L'invention concerne un tube pour lingotière de coulée continue d'aciers, notamment d'aciers péritectiques. Ce tube comporte une première section longitudinale (1) intégrant une position prédéterminée de surface du bain (h), et une deuxième section longitudinale (2) faisant suite à la première. La première section longitudinale (1) comprend une couche calorifuge (16) dont les dimensions sont telles que la résistance à la chaleur du tube de lingotière (10) dans la première section longitudinale (1) est supérieure à celle de la deuxième section longitudinale (2). La couche calorifuge (16) remplit une région allant de la surface extérieure (11) du tube de lingotière (10) à une distance équivalente à 75 % au maximum de l'épaisseur de paroi (dw) du tube de lingotière (10), mesurée à partir de la surface extérieure (11) de ce dernier. Un choix approprié du profil d'épaisseur de la couche calorifuge dans le sens d'extraction du brin (14) permet de réguler un profil de température prédéfini sur la face intérieure du tube de lingotière lors d'une opération de coulée et d'optimiser la croissance d'une croûte solidifiée de barre de coulée continue.
