Title (EN) REFRACTORY LINING STRUCTURE
(FR) STRUCTURE DE REVÊTEMENT RÉFRACTAIRE
Abstract:
(EN) A refractory lining structure (18) for a metallurgical vessel is characterized by at least one elongated expansion joint (50) formed in and extending through the surface of the working lining in a substantially vertical direction. The elongated expansion joint accommodates thermal expansion of the working lining (20) in a metallurgical vessel such as, for example, a tundish during preheating for a continuous casting operation. The elongated expansion joint decreases crack formation, delamination, and spalling of the working lining from underlying back-up linings and/or safety linings in metallurgical vessels during preheating and use, while still facilitating metal skull removal after the completion of metallurgical operations.
(FR) L'invention concerne une structure de revêtement réfractaire (18) destinée à un récipient métallurgique et caractérisée par au moins un joint de dilatation allongé (50) formé dans la surface du revêtement de travail et s'étendant à travers ladite surface dans une direction sensiblement verticale. Le joint de dilatation allongé reçoit la dilatation thermique du revêtement de travail (20) dans un récipient métallurgique tel que, par exemple, un panier de coulée pendant le préchauffage pour une opération de coulée continue. Le joint de dilatation allongé réduit la formation de fissures, le délaminage et l'écaillage du revêtement de travail à partir de revêtements de secours et/ou de revêtements de sécurité sous-jacents dans des récipients métallurgiques pendant le préchauffage et l'utilisation, tout en facilitant l'élimination du fond de poche métallique après l'achèvement d'opérations métallurgiques.
