Abstract
The disclosure embraces a sealing member for the joint between an outlet of a casting ladle and a closure member for the outlet and includes a rigid core member having an opening in which is located a tubular casing which fits into the aperture of the outlet of the casting ladle and a closable bore of the closure member; the rigid core member is coated with mortar material in a paste or semi-fluid form; the sealing member is encased in an air-tight package so as to prevent the mortar material from solidifying prior to its incorporation into the joint between the outlet of the casting ladle and the closure member.
