The present invention provides a coating layer of the coke oven having a high strength, high impact resistance and excellent smoothness to enable long term protection of the fire brick of the coke oven. Carbon adhered to the brick can be removed by spraying a coating agent with a glaze layer mainly composed of 18 to 70% by weight of SiO2 and 10 to 60% by weight of Na2O and/or K2O and containing one or a plurality of 2 to 14% by weight of P2O5, 0.5 to 25% by weight of BaO, 0.5 to 25% by weight of SrO and 0.5 to 20% by weight of Fe2O3 onto the surface of a high temperature firebrick, thereby obtaining an excellent coating layer.

Un four de cokéfaction est revêtu d'un film de revêtement présentant une résistance mécanique élevée, une résistance aux chocs élevée, un excellent poli, ainsi qu'une longue durée de vie, et qui peut protéger longtemps les briques réfractaires du four de cokéfaction. Selon l'invention, un matériau de revêtement qui comprend, comme substance principale, 18 à 70 % en poids de SiO2 et 10 à 60 % en poids de NaO et/ou K2O, et contient au moins un des composants suivants: 2 à 14 % en poids de P2O5, 0,5 à 25 % en poids de BaO, 0,5 à 25 % en poids de SrO, et 0,5 à 20 % en poids de Fe2O3, est pulvérisé sur les briques réfractaires pour enlever le carbone ayant adhéré auxdites briques et forme une excellente couche de revêtement.
