Abstract

Inventia se refera la o duza metalurgica pentru elaborarea otelului, utilizata la insuflarea unor fluide în topitura metalica în vederea afinarii acesteia. Duza metalurgica, conform inventiei, este alcatuita din doua tevi concentrice, teava interioara fiind prevazuta la capatul superior cu un ajutaj conic în prelungirea caruia este montat un ajutaj cu prag. Aceasta constructie permite intensificarea procesului de afinare a topiturii metalice, precum si reducerea consumului de feroaliaje.
