Abstract
LA INVENCION SE REFIERE A UN PROCESO PARA EL RECALENTAMIENTO POR METALOTERMIA DE UN BAÑO DE ACERO LIQUIDO CONTENIDO EN UN RECIPIENTE METALURGICO, EN EL QUE SE INTRODUCE UN COMBUSTIBLE Y BAJO LA SUPERFICIE DEL CUAL SE INYECTA GAS OXIDANTE Y UN GAS DE AGITACION. SEGUN LA INVENCION, SE CREA EN EL BAÑO UNA CORRIENTE CONTROLABLE QUE RESULTA DE LA INYECCION DE UNA GAS DE AGITACION, POR UN MEDIO DISTINTO DEL MEDIO DE INYECCION DEL GAS OXIDANTE, Y SE INTRODUCE EL COMBUSTIBLE METALICO EN ESTA CORRIENTE, DE MANERA QUE ENTRE EN CONTACTO CON EL GAS OXIDANTE.
