Abstract
PURPOSE:To easily and surely remove stuck metal in a molten metal vessel without any damage to the lining by combining energies of high pressure water and high temp. flame. CONSTITUTION:To the metal 2 sticking to an opening part or internal side wall, etc., in the above vessel of converter, etc., an injection nozzle forming the high temp. flame burner 10 of LPG flame, etc., at center part and the high pressure water nozzle 13 around the burner 10 at the equal interval so as to concentrate the high pressure water to the tip of the flame, is used. At the same time of detaching the metal with the high temp. flame from the burner 10 by colliding the high pressure water, the firmly stuck metal 2 layer is effectively detached and removed by cooling effect with the water and by inducing a kind of steam explosion caused by quick volume expansion from the water to the steam. Further, by regulating the water pressure of the high pressure water to lower level, only the metal 2 layer is selectively removed and the damage of the refractory 15 can be avoided.
