<p>A method and equipment for correcting the temperature of hot metal are provided to prevent solidification of hot metal and prevent facility accidents such as a fire due to the solidification of the hot metal by thermally insulating or increasing temperature of hot metal consistently although charging waiting circumstances of hot metal are maintained for a long time. In equipment for correcting the temperature of hot metal in charging waiting circumstances of hot metal, the equipment comprises a hot metal ladle burner(10) which is installed in an upper part of a hot metal ladle in a way that an upper space of the hot metal ladle can be opened or closed, and which corrects or increases temperature of the hot metal by combustion heat of the combustible gas by injecting a combustible gas supplied from the outside into the hot metal ladle and burning the combustible gas. The hot metal ladle burner includes a heat protection cover(13), a heat burner(11), a heat burner case(12), an exhaust port(14), and a temperature measuring part(15). The heat protection cover has shaped refractories(13a) constructed therein to prevent degradation of the heat protection cover by reducing contraction and expansion due to a temperature change between the outside and the inside of the heat protection cover.</p> |
