Abstract
Invenţia se referă la metalurgie, şi anume la producerea şi prelucrarea metalului lichid.Dispozitivul gurii de vânt pentru introducerea mediilor gazoase sub un strat de metal lichid conţine un bloc cu locaş din material refractar, în care este încorporată o bucşă, formată din nişte ţevi metalice coaxiale, având pe partea prevăzută pentru introducerea în metalul lichid cel puţin un canal de lucru central şi cel puţin un canal de lucru inelar. Aceste canale de lucru sunt unite separat cu nişte racorduri pentru debitarea mediilor gazoase în metal. Ţevile metalice coaxiale constau după lungime din două secţii îmbinate reciproc de diferite diametre, prima dintre care are un diametru mai mic şi este destinată pentru debitarea mediilor gazoase în metalul lichid, iar a doua are un diametru mai mare şi este unită cu nişte racorduri pentru debitarea separată a mediilor gazoase în canalele de lucru ale primei secţii. Secţia a doua conţine o ţeavă metalică suplimentară şi este executată numai cu canale de lucru inelare, ţeava interioară a căreia este închisă la ambele capete şi este umplută cu material refractar, iar jocurile canalelor de lucru inelare ale acestei secţii formează capilare pentru metalul lichid.
