Abstract

Inventia se refera la un procedeu pentru protejarea duzelor si camasuielii refractare ale unei cuve metalurgice pentru afinarea de topituri metalice, îndeosebi de fonta bruta, în zona unui dispozitiv de insuflare, aflat sub nivelul topiturii precum si la un dispozitiv pentru realizare aprocedeului. Procedeul consta în aceea ca un lichid constituit din cel putin un compus hidroxilic si apa sau numai din apa, este pulverizat prin intermediul unui gaz purtator, sub presiunr si insuflat în topiturametalica în aceasta stare, sau în stare de vapori. Dispozitivul de insuflare pentru aplicarea procedeului este constituit dintr-o duza avînd ces putin trei tevi concentrice, prevazute cu o anumita distanta în sens radial între ele si alcatuind un canal central si niste canale inelare precum si niste orificii de admisie pentru alimentarea duzei si a materialului refractar al campsuielii, cresterea duratei de serviciu a dispozitivului de insuflare a gazelor si simplitatea constructiei dispozitivului, sînt avantaje ale acestei inventii.
