Abstract

L'invention concerne une paroi latérale (1) d'une lingotière de coulée continue, dans laquelle est tout d'abord pratiqué un évidement auxiliaire (11, 16) qui s'étend dans la direction longitudinale au moins sur la longueur d'évidement (L) de l'évidement utile (10) et orthogonalement à la direction longitudinale d'une section transversale auxiliaire. Dans l'évidement auxiliaire (11, 16) est ensuite introduit un élément supplémentaire (13, 14, 17) qui s'étend dans la direction longitudinale au moins sur une longueur d'évidement (L) d'un évidement utile (10) ultérieur et qui, vu orthogonalement à la direction longitudinale, délimite l'évidement utile (10) au moins sur une partie de sa circonférence. L'évidement utile (10) est formé par l'introduction de l'élément supplémentaire (13, 14, 17) dans l'évidement auxiliaire (11, 16). L'évidement utile (10) est fermé sur son pourtour orthogonalement à la direction longitudinale. Il présente orthogonalement à la direction longitudinale une section transversale utile (petite en conséquence) et une étendue utile maximale (d3). La section transversale utile est définie de telle manière qu'un guide d'onde optique (9) peut être introduit de manière réversible dans l'évidement utile. Le procédé de fabrication permet d'obtenir un rapport entre la longueur d'évidement (L) et l'étendue utile maximale (d3) de 100:1 ou davantage.
