Abstract

Inventia se refera la o gura de vînt pentru torcretare, utilizata în metalurgia feroasa, si anume, pentre repararea captuselilor agregatelor metalurgice. Gura de vînt pentru torcretarea cu flacara, formata dintr-un corp racit cu apa, consta din souatevi concentrrice. în interiorul acestui corp, racit cu apa, sînt dispuse concentric tevile pentru debitarea amestecului pulverulent de material refractar cu combustibil si tevile pentru debitarea oxigenului. La capatul de iesire al acestor tevi, de-alungul peretilor lor, sînt montate ajutaje pentru debitarea amestecului pulverulent de material referactar cu combstibil si ajutaje pentru debitarea oxigenului, dispuse perechi. Forma si constructia ajutajelor este diferita si, în functie de aceasta forma, gurile de vînt echipate cu maximum de eficienta la torcretarea de agregate metalurgice de diferite dimensiuni, forme si suprafete.
