FIELD: metallurgy.
SUBSTANCE: apparatus has heat-insulating cover, burner, smoke removal unit, and flexible device for sealing gap between cover and ladle upper edge. Sealing device is made from flexible refractory material in the form of set of rolls which overlap ladle upper edge. Rolls of refractory material are provided along perimeter of lower generatrix of cover. Roll ends are oriented toward upper edge of ladle. Rolls are fastened by means of clips welded to cover skirt. Apparatus may be used in both vertical and horizontal versions.
EFFECT: increased efficiency in drying and high-temperature heating of ladle lining and wider range of usage.
