Abstract

Patente de Invenção: "MéTODO E DISPOSITIVO PARA FUNDIR MATERIAL METALìFERO EM FORMA DE PARTìCULAS FINAS COMO ESPONJA DE FERRO". A presente invenção refere-se a um processo e a um dispositivo para fundir material metalífero preferivelmente material metalífero em forma de partículas finas, como esponja de ferro, em um forno de fundição (1) metalúrgico, no qual dentro de uma câmara interna (11) do forno de fundição (1), um metal líquido (5) e uma camada de escória (6) flutuante sobre o metal líquido (5) são mantidas verticalmente, sendo alimentados o material metalífero por meio de um dispositivo de alimentação de imersão na camada de escória (6) e a energia em forma de arcos voltáicos (14) elétricos, o material metalífero é introduzido por via direta na região central (Z) do forno de fundição (1) por meio de pelo menos um tubo de alimentação (8) destinado exclusivamente ao transporte através do correspondente bocal do tubo de alimentação (9), os arcos voltáicos (14) são dirigidos em direção oblíqua à região central (Z) do forno de fundição (1) sobre o metal líquido (5) e o material metalífero é derretido na camada de escória (6) e um processo de mistura escória - metal líquido é mantido na região do bocal do tubo de alimentação (9).
