Abstract
METODO PARA EVITAR EL DAÑADO DE UNA TOBERA SUMERGIDA USADA EN UN HORNO DE FABRICACION DE ACERO CON OXIGENO, EN UN PROCESO DE AFINO POR DESCARBURACION. COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, SE FORMA UNA MEZCLA DE GAS-POLVO COMPUESTA POR UN MATERIAL EN PARTICULAS QUE EMITE GAS EN UNA CANTIDAD SUFICIENTE Y POR UN GAS PORTADOR DISTINTO DEL OXIGENO; SEGUNDA, SE INSUFLA LA MEZCLA DE GAS-POLVO EN UN BAÑO DE METAL FUNDIDO A TRAVES DE LA TOBERA SUMERGIDA, AL OBJETO DE FORMAR UNA CAPA DE DICHA MEZCLA SOBRE EL BORDE PERIFERICO INTERNO DE LA MENCIONADA TOBERA; Y POR ULTIMO, SE ENFRIA EL METAL FUNDIDO EN TORNO AL EXTREMO DE DICHA TOBERA SUMERGIDA MEDIANTE LA ABSORCION DE CALOR, OCASIONADO POR LA REACCION ENDOTERMICA DE DESCOMPOSICION DEL MATERIAL EN PARTICULAS, AL TIEMPO QUE ES AGITADO EL BAÑO DE METAL FUNDIDO POR EL CHORRO DE GAS DESPRENDIDO.
