Abstract

La présente invention concerne un placage résistant au feu qui inhibe l'apparition de l'endommagement d'une surface sur une surface coulissante lorsqu'elle reçoit de l'acier possédant une concentration en oxygène particulièrement faible dans une masse fondue, telle qu'un acier calmé à l'Al. Le placage résistant au feu de la présente invention comporte de 15 % en masse à 45 % en masse d'un constituant Al4O4C, de 2,0 % en masse à 4,5 % en masse d'un constituant carboné libre, de 0,5 % en masse à 4,0 % en masse d'un constituant SiO2, et 1,0 % en masse ou moins (0 inclus) d'un constituant d'aluminium métallique, le constituant principal du reste étant un constituant Al2O3 en tant que constituant principal. Le placage comprend une surface qui sert de surface coulissante, et possède une perméabilité inférieure ou égale à 40×1017m2 dans une direction orthogonale à ladite surface servant de surface coulissante, et une porosité apparente inférieure ou égale à 11,0 %.
