Abstract
A method and product improve the positioning of loose anti-skulling material in the outlet nozzle zone of a metallurgical pouring vessel. The formation of skull in the outlet nozzle zone of a metallurgical pouring vessel is inhibited by positioning in the outlet nozzle zone an elongated container containing loose anti-skulling material, the container being formed of an intumescent material so that when heated it expands to fill the gap between itself and the walls of the nozzle and releases the anti-skulling material.
