Abstract

POSTOPEK SEGREVANJA JEKLENIH TALIN, KOT TUDI PRIPRAVA ZA IZVEDBO TEGA POSTOPKA, pri postopku segrevanja jeklenih talin (10) v ponvi (5), prekritih z žlindro (8), bogato z železovimi oksidi, ob uporabi metalotermične toplote, med polnjenjem ponve (5) vpihujemo skupaj z inertnim plinom skozi šobe (14) v dnu (12) ponve (5) za kopel/žlindro, kovino, ki reagira eksotermno s kisikom iz kopeli/žlindre, kot Al, Si, njune zmesi ali zlitine, kot tudi v danem primeru uprašene snovi, ki tvorijo žlindro. Priprava za izvedbo postopka ima ponev (5) z najmanje eno talno šobo (14), povezano s pnevmatsko transportno napravo (11) za metalotermično učinkovite snovi. Predvideno je lahko več šob (14,16) v razmiku od stene ponve (5), razvrščenih koncentrično na steno ponve (5) na premeru, ki je 50-70% premera ponve (5). Talne šobe (14,16) so razvrščene na enaki razdalji po obodu plaščne krivulje. Za vsako talno šobo (14), priključeno na pnevmatsko transportno napravo (11), so predvidene 1-3 z inertnim plinom napajanje talne šobe (16).PROCESS FOR HEATING STEEL MELT, AS WELL AS PREPARING TO PERFORM THIS PROCEDURE, in the process of heating steel melts (10) in a pan (5) covered with slag (8) rich in iron oxides, using a metal thermal pan (5) blow together with the inert gas through the nozzles (14) in the bottom (12) of the bath / slag pan (5), a metal that reacts exothermically with oxygen from the bath / slag, such as Al, Si, mixtures or alloys thereof, as well as in a given in the case of dusty slag-forming substances. The device for carrying out the process has a pan (5) with at least one floor nozzle (14) connected to a pneumatic transport device (11) for metallothermally active substances. Several nozzles (14, 16) may be provided spaced from the wall of the pan (5), arranged concentrically on the wall of the pan (5) at a diameter which is 50-70% of the diameter of the pan (5). The floor nozzles (14,16) are arranged at the same distance around the circumference of the mantle curve. For each floor nozzle (14) connected to the pneumatic conveying device (11), 1-3 inert gas supply to the floor nozzle (16) is provided.
