ABSTRACT:
Sealing rings are provided for ladle preheaters. The rings are mounted for relative movement into a stable, suspended position over the primary lining. Refractory fiber insulation is provided in the form of modules on an outer support ring. The rings seal about the ladle rim adjacent burner and flue openings of the preheater. Since the sealing ring may move over the primary lining, the ladle rim forms a seal with the modules and also forces the support ring into a second seal with the primary lining when the lining is refractory ceramic fiber.
