Abstract
A replacement product for a portion of a castable refractory surface contains a precast refractory piece with accommodation for an adjustable positioning structure for conforming the working surface of the precast refractory piece to the castable refractory surface. A process for installing the precast refractory piece includes positioning the precast refractory piece with respect to the castable refractory surface, and introducing castable material into an interface volume between the precast refractory piece and the castable refractory surface.
Claims11
A precast refractory piece, comprising:
- a first surface,
- a second surface, disposed opposite the first surface,
- an engagement channel, extending through the precast refractory piece from the first surface to the second surface, and
- an adjustable engagement device in communication with the second surface and with the engagement channel.
A method for repairing the surface of a refractory structure, comprising:
- a. supplying a precast refractory piece having a first surface and a second surface opposite to the first surface, and an engagement channel extending through the precast refractory piece from the first surface to the second surface, and an adjustable engagement device in communication with the second surface and with the engagement channel;
- b. placing the precast refractory piece in proximity to a refractory structure to be repaired;
- c. inserting a rod in the engagement channel and within the adjustable engagement device;
- d. adjusting the rod to adjust the position of the precast refractory piece;
- e. arranging the precast refractory piece and the structure to be repaired to at least partially enclose an interface volume between the precast refractory piece and the structure to be repaired;
- f. providing a pumping port communicating between the exterior and interior of the interface volume;
- g. inserting castable refractory into the interface volume, and
- h. removing the rod from the engagement channel.
