Abstract
L'invention concerne une pièce pour la coulée d'acier comportant un corps (2) réalisé en un matériau réfractaire comportant du carbone. Elle comporte une couche (10) revêtant partiellement ou entièrement le corps et apte à former une couche (10a) imperméable au gaz, oxydée et densifiée lorsqu'elle est portée à une température supérieure à 1000 .degree.C. La couche (10) est constituée d'un matériau réfractaire comportant des précurseurs de frittage choisis dans le groupe comprenant l'alumine calcinée, l'alumine calcinée réactive, la fumée de silice, les argiles.
