Zusammenfassung:	1124510 Removing incrustations in furnaces UNION CARBIDE CORP 17 Nov 1965 [9 Dec 1964] 48755/65 Headings C5G and G10B Patching by flame spraying of the working face of a steel-making furnace wall is facilitated by removing slag impregnated refractory by directing at an acute angle against said working face, a flame from an internal combustion burner supplied with fuel, oxidant and CaF2 powder. The powder is fed either with the fuel or in an air-stream and O 2 is supplied to the combustion chamber. In a specific embodiment the burner was inclined at 45 degrees to and 7-10 ins. from the affected panel and traversed thereover at speeds greater in one direction than the other.
