Abstract
Disclosed is a casting nozzle intended to suppress or prevent breaking of a nozzle body thereof. The casting nozzle comprises: a nozzle body; a metal casing disposed to surround an upper end of the nozzle body to form a gas pool between an outer peripheral surface of the upper end of the nozzle body and an inner peripheral surface of the metal casing; and a bridging segment provided in at least a part of the gas pool to bridge between the outer peripheral surface of the upper end of the nozzle body and the inner peripheral surface of the metal casing.
