Abstract

"DESCARREGADOR DE FERRO REDUZIDO EM UM FORNO DE REDUçãO DE SOLEIRA ROTATIVA". Um descarregador de ferro reduzido em um forno de redução de soleira rotativa colhe ferro reduzido sobre uma soleira rotativa a partir de um lado frontal com o uso de um impulsor longo o bastante cobrir toda a largura da soleira rotativa, faz o ferro reduzido cair sobre um transportador vibratório montado no impulsor e descarga o mesmo a partir de uma saída para o exterior do forno de redução. O descarregador de ferro reduzido envolve um desperdício estrutural mínimo e dá um rendimento satisfatório.
