FIELD: process engineering.
SUBSTANCE: teeming nozzle comprises at least of on claw (2) extending radially around lengthwise axis (A). Note here that central space located between one or several claws (2) and lengthwise axis (A) serves to accommodate filling pipe (1) shaped, in fact, to cylinder. It differs from known designs in that inner surfaces of at least one claw (2) located opposite central space is shaped flat and provided with ledges (2) and/or recesses (22) of preset seizes. Note here that ledges (12) and/or recesses (22) are distributed relative to each other in a definite way to fit in conjugate grooves (11) and/or ledges (21) made at filling pipe outer side. Note here that at least one claw (2) slides across lengthwise axis (A) between expanded position to fit pipe (1) in central space and drawn-up position to allow inner surface of claws (2) to extend on to outer surface of pipe (1). Note that said nozzle includes locking element 3 sliding relative to base (15, 16) and at least one claw (2) between position whereat it locks claws (2) in drown-up position and in active position whereat it allows claws (2) displace to extended position.
EFFECT: perfected design.
