Abstract

Procedeul continuu de obtinere a fontei, conform inventiei, prevede reducerea directa a minereului de fier oxidic sub forma de macroparticole într-un cuptor cu cuva în care minereul circula descendent în contracurent cu gaze redusatoare în intervalul de temperaturi cuprinse între 760-900 degree C, urmata de topirea macroparticolelor de fier metalizat într-o camera de topire-gazeificare în care se injecteaza combustibil solid sau lichid în amestec cu oxigen pentru realizarea topirii macroparticolelor de fier metalizat si gazeficarea combustibilului. în scopul optimizarii fluxului tehnologic se efectueaza alimentarea directa a macroparticolelor de fier metalizat, avînd temperatura de 700 degree C, fie în baia de metal topit mentinuta constant în camera de topire, gazeificare, fie pe vatra centrala a acestuia si injectarea combustibilului, de preferinta solid fin granulat, ales între lignit, mangal si cocs, si a oxigenului, fie sub suprafata baii de metal, fie deasupra baii de metal sau gramezii de macroparticole de pe vatra, cu mijloace de insulflare sa izbeasca suarafata baii de metal si respectiv gramada de macroparticole solide de pe vatra, realizîndu-se astfel topirea macroparticolelor de fier metalizat, rezultînd un gaz rezidual fierbinte, care se raceste la circa 1200 degree C, prin suflarea apei..........
