Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method preventing scattering of dust generated in overhauling a refractory and satisfying predetermined environmental standard in work environment by spraying mist in a wide range. SOLUTION: This method prevents the scattering of the dust generated in overhauling the refractory 13 arranged inside a molten steel vessel 10 for carrying molten steel. Mist with a particle diameter of ≥60 μm and ≤150 μm is sprayed using a spray nozzle 20 for mixing water with air. COPYRIGHT: (C)2011,JPO&INPIT
