ABSTRACT:
Method and apparatus to spray the interior surface of a refractory lined vessel that receives molten metal where the interior refractory surface of the vessel is most prone to erode. Supply pipes are introduced into the vessel and are pivotally supported on an upper portion of the vessel to pivot about angularly related axis, such as horizontal and vertical axis. Said pipes are pivoted around at least one of said axis while water is propelled through said elongated pipe to a corroded portion of said interior surface to remove scale from and clean said corroded surface. Air entrained granulated refractory material, preferably mixed with water to form a slurry, is propelled through said pipe to coat the clean interior surface. A movable end portion is hingedly connected to said elongated pipe to provide for the angular control of said movable end portion. When said elongated pipe is in an elevated position, said movable end portion can be positioned so that it is at a substantially perpendicular portion relative to the wall to increase the impact of the propelled material onto said wall. The two process operation is repeated for at different locations around the periphery of the vessel to clean and reline the entire wall portion, if required. Alternatively, all eroded portions may be cleaned in turn followed by relining each portion.
