Abstract
A method is provided for restoring a refractory lining for repeated use. The lining is present on a underlying wall surface and is still hot from a previous use when one induces thermal shock in the lining (e.g. by spraying water on it) so as to loosen it. The loosened pieces are then pried away from the wall surface, and they are removed from the area. The residual lining is milled to expose a sound, underlying wall surface, and fine particles, dust, and milled-off pieces are removed. The underlying wall surfaces are thus made speedily available for relining and reuse.
Claims12
A method of restoring a refractory lining for repeated use, the lining, having residue thereon, being present on an underlying wall surface, comprising the steps of:
- while the lining is still hot from a previous use, inducing thermal shock in the lining so as to loosen the residues;
- prying the loosened residue pieces away from the wall surface;
- removing the loose pieces from the wall surface area;
- milling the residual lining to expose the sound, underlying wall surface;
- and
- removing fine particles, dust, and milled-off pieces from the wall surface area, whereby the underlying wall surface is speedily available for relining and reuse.
