Patent

CA 2187623

The disclosed invention provides a method of forming refractory linings for maintaining refractory linings against attack by corrosive materials such as those present in steel manufacture. The method entails spraying an aqueous mixture of a refractory composition that includes at least one refractory material onto the working surface of a refractory lining. Spraying is performed to provide one or more layers of the refractory composition on the refractory lining after each exposure of the lining to corrosive materials such as those incurred in steel manufacture.

Cette invention se rapporte à un procédé de fabrication de revêtements réfractaires, et à un procédé visant à protéger les revêtements réfractaires de l'attaque des matériaux corrosifs, tels que ceux présents dans la fabrication de l'acier. Le procédé consiste à pulvériser un mélange aqueux d'une composition réfractaire comprenant au moins un matériau réfractaire se trouvant sur la surface de travail d'un revêtement réfractaire. Pour former une ou plusieurs couches de la composition réfractaire sur le revêtement réfractaire, on effectue une pulvérisation après chaque exposition du revêtement à des matériaux corrosifs, tels que ceux utilisés dans la fabrication de l'acier.
