Abstract
An external plating arrangement for improved effectiveness in sealing off the cold end face of a refractory body, wherein the side walls of the body are sheathed with metal plates and planar portions extend normally from the plates and overlie the cold end face for encasing the perimeter of the cold end face. A separate metal plate may cover the cold end face, the planar portions having a form of elongated tabs for overlying the end plate. Alternatively, the planar portions may be right triangular for completely covering the cold end face, or one of the planar portions may be rectangular for covering the cold end face, the other planar portions being elongated tabs overlying the rectangular plate.
