ABSTRACT:
A preheater for uniformly heating the refractory lining of a ladle, ingot mold or the like. A concave, refractory lined cover is provided with one or more flues for exhausting noxious fumes and products of combustion. There is also provided an axially extending burner for projecting a flame onto the walls of the ladle refractory lining. Fluid operated means are provided for vertically tilting the boom which pivotally supports the ladle cover to enable the cover to be laid, with a tight fit, on the mouth portion of the ladle, - also to enable lifting of the cover and lateral swinging thereof from the closed position. A modification, particularly suitable for large ladles, is to provide a plurality of burners which emit flames substantially tangentially inwardly of the cover to uniformly heat the ladle lining.
