Abstract

L'invention concerne un procédé destiné à poser par liaison un revêtement protecteur sur une surface exposée à l'usure d'une tuile de carbone. Ce procédé consiste à appliquer, sur cette surface exposée à l'usure, au moins une couche d'une pâte de matière réfractaire particulaire en suspension dans un support polymère inorganique et/ou colloïdal comprenant une dispersion de particules colloïdales et/ou une solution de particules polymères inorganiques d'oxyde de métal liant, puis à traiter par voie thermique la ou les couches de pâte appliquées en vue de consolider la matière réfractaire particulaire dans l'oxyde de métal liant, d'où la formation dudit revêtement protecteur. Un composé de carbone hydrophobe comprenant un substituant hydrophile, tel que OH, -SO¿3?Na ouCOOH, est utilisé dans la pâte sous la forme d'un agent liant permettant de lier l'oxyde de métal liant à la tuile de carbone par liaison à la surface exposée à l'usure de la tuile de carbone, le substituant hydrophile étant lié à l'oxyde de métal liant. De préférence, le revêtement protecteur comprend, sur la ou les couches renfermant le composé de carbone hydrophobe, une ou plusieurs couches de matière réfractaire sensiblement exemptes de carbone élémentaire ou de composé de carbone organique.
