Abstract

L'INVENTION CONCERNE UN PROCEDE ET UN DISPOSITIF DE PRODUCTION D'ACIER AU CARBONE ET D'ACIER FAIBLEMENT ALLIE DANS UN FOURNEAU A SOUFFLAGE A OXYGENE ET SOUFFLAGE PAR LE FOND. SELON L'INVENTION, UN PROCEDE DE PRODUCTION D'ACIER DE CARBONE ET D'ACIER FAIBLEMENT ALLIE DANS UN FOURNEAU A SOUFFLAGE A OXYGENE (MONTRE DANS LA FIGURE) EST REVELE, DANS LEQUEL LE FLUX G DU GAZ DE SOUFFLAGE PAR LE FOND, COMPOSE EN PREDOMINANCE, DE DIOXYDE DE CARBONE EST INTRODUIT DANS LE METAL EN FUSION 3 A TRAVERS AU MOINS UNE BUSE 2 MONTEE DANS LE FOND OU SUR LES FACES LATERALES DUDIT FOURNEAU A SOUFFLAGE A OXYGENE 1 PENDANT AU MOINS UNE PARTIE DU TEMPS ENTRE LE COMMENCEMENT DU SOUFFLAGE ET LE DEBOUCHAGE DE LA MASSE EN FUSION. L'INVENTION S'APPLIQUE NOTAMMENT A L'INDUSTRIE METALLURGIQUE.The invention relates to a method and a device for producing carbon steel and low alloy steel in a furnace with oxygen blowing and bottom blowing. ACCORDING TO THE INVENTION, A PROCESS FOR THE PRODUCTION OF CARBON STEEL AND LOW ALLOY STEEL IN AN OXYGEN BLOWER (SHOWN IN THE FIGURE) IS REVEALED, IN WHICH THE FLOW G OF BOTTOM BLOW GAS, CONSISTS OF PREDOMINANTLY, CARBON DIOXIDE IS INTRODUCED INTO THE MOLTEN METAL 3 THROUGH AT LEAST ONE NOZZLE 2 MOUNTED IN THE BOTTOM OR ON THE SIDE FACES OF THE SAID OXYGEN BLOWER 1 DURING AT LEAST PART OF THE TIME BETWEEN THE BEGINNING OF BLOWING AND THE UNCLOGGING OF MERGING MASS. THE INVENTION APPLIES IN PARTICULAR TO THE METALLURGICAL INDUSTRY.
