Abstract
Procedeul de torcretare cu flacara a agregatelor metalurgice, care cuprinde debitarea unui amestec de material refractar si de combustibul sub forma unui jet inelar, concentric în raport cu jetul bifazic de material refractar si de combustibil, încalzirea si fuziunea materialului refractar cu flacara si depunerea particvulelor de material refractar pe suprafata captuselii se realizeaza prin aceea ca jetul inelar de oxigen se îngusteaza si este rasucit în jurul propriei sale axe, iar raportul între impulsul de racire a jetului de oxigen si impulsul jetului de material refractar si de combustibil se mentine în limitele 0,3...3,0.
