| PURPOSE: To prolong a still time o a cooling zone in casting a thin slab by producing a soot layer with directing a flame having reduction effect to a surface to be coated and acting a neutral flame to a soot layer. CONSTITUTION: A surface coming into contact with a liquid metal of steel etc., is coated by a soot resulting from combustion of a combustible gas. In this case, a gas mixture is adjusted so as to have reduction effect, a soot layer is formed by directing a flame to a surface to be coated. A post treatment, in which an actually neutral flame, e.g. a flame of a gas or a gas mixture not having oxidation effect, reduction effect is applied to the soot layer. By using a gas mixture composing of a combustion gas and oxygen for a post treatment, an oxygen content in the gas is stoichiometrically adjusted corresponding to a carbon content in the combustion gas. As a combustion gas for the post treatment, acetylene or a city gas is used. By this method, a still time of a cooling zone in casting a thin slab is prolonged. COPYRIGHT: (C)1990,JPO | ||||||
