Abstract

"PROCESSO E DISPOSITIVO PARA O DERRAMAMENTO DEMASSAS FUNDIDAS METáLICAS ISENTO DE ESCóRIA DERECIPIENTES DE FUSãO METALúRGICOS". Durante aextração da massa fundida metálica (5) de um recipiente de fusãometalúrgico (1) por derramamento existe o risco da escória fundida(6) que recobre a massa fundida metálica (5) ser arrastada juntocom esta última. A fim de se deter tal arrasto indesejável deescória, é proposto, de acordo com a presente invenção, soprarum fluido através do orifício de derramamento (4) do recipiente defusão metalúrgico (1) e sobre a superfície do banho (7) por meio deuma lança de sopro (20) que é disposta fora do recipiente de fusão(1),de modo que a escória fundida (6) seja afastada do orifício dederramamento (4), sendo, deste modo, impedida de sair. (Figura dedesenho).
