PURPOSE:To obtain a thermal spraying repairing material having a strong adhesiveness between a formed sprayed layer and a furnace surface even in case of a low temperature, e.g. 600 deg.C, of a damaged part (a part to be repaired) of a furnace, without decreasing a working circumstance owing to little noise in spraying and excellent in workability. CONSTITUTION:2-20wt.% metallic silicon powder having <=100mum average size and 0.5-5wt.% aluminum-magnesium alloy powder having <=100mum average particle size are compounded to a main component of a refractory fine powder. |
