Abstract
A protective nozzle for the outlet passage of a casting ladle includes a body having a conical shape and a through bore with the exterior side surfaces of the body having projections or ridges which aid in the retention and establishing of a mortar joint between the wall of the outlet of the casting ladle and the exterior surface of the nozzle so as to prevent the possibility of the mortar material being washed out of the joint between the nozzle and the walls of the outlet passage of the casting ladle during a casting operation.
