THERMAL SPRAYING REPAIR METHOD FOR REFRACTORY
PROBLEM TO BE SOLVED: To provide a thermal spraying repair method capable of prolonging a service life of a repair refractory so as to prevent the repair refractory from being peeled from a damage part of a refractory, and capable of preventing abrupt temperature rise of a steel shell.SOLUTION: A thermal spraying repair method for refractory comprises thermally spraying, to a damage part 11 of a silica brick refractory 10, a first repair refractory 13 containing SiOor 50 mass% or more as a thermal spraying pre-composition (converting to SiOin a case of containing metal Si). The thermal spraying repair method also comprises thermally spraying, before thermally spraying the first repair refractory 13, a second repair refractory 12 that contains SiOor 50 mass% or more as a thermal spraying pre-composition (converting to SiOin a case of containing metal Si), and whose melting point depression margin to the first repair refractory 13 is within a range of 10-100°C.SELECTED DRAWING: Figure 1
【課題】耐火物の損傷部から補修耐火物が剥離しないようにして補修耐火物の長寿命化を図ると共に、鉄皮温度の急激な上昇を防止することが可能な耐火物の溶射補修方法を提供する。【解決手段】珪石レンガ耐火物１０の損傷部１１に、溶射前組成としてＳｉＯ２を５０質量％以上含有する（金属Ｓｉを含む場合はＳｉＯ２に換算する）第１の補修耐火物１３を溶射施工する耐火物の溶射補修方法であって、第１の補修耐火物１３を溶射する前に、溶射前組成としてＳｉＯ２を５０質量％以上含有し（金属Ｓｉを含む場合はＳｉＯ２に換算する）、第１の補修耐火物１３に対する溶融点降下代が１０℃〜１００℃である第２の補修耐火物１２を溶射施工する。【選択図】図１
