Abstract

MÉTODO E SISTEMA PARA AQUECER FERRO REDUZIDO DIRETO ENTRE UMA FONTE DE FERRO REDUZIDO DIRETO E EQUIPAMENTO DE PROCESSAMENTO PARA O FERRO REDUZIDO DIRETO, E, CONJUNTO DE AQUECEDORES DE CONDUÍTES DE ALIMENTAÇÃO. Um método para aquecer ferro reduzido direto entre uma fonte de ferro reduzido direto e equipamento de processamento para o ferro reduzido direto, compreende prover um conjunto de aquecedores de conduítes entre a fonte de ferro reduzido direto e o equipamento de processamento, em que o conjunto de aquecedores de conduítes recebe um fluxo do ferro reduzido direto da fonte de ferro reduzido direto e aquece o ferro reduzido direto à medida que o ferro reduzido direto flui através do conjunto de aquecedores de conduítes e para o equipamento de processamento.
