Abstract

patente de invenção: <b>"método de operação de forno vertical".<d> um método para operar um forno de cuba que compreende carregar o forno com uma fonte de ferro que possui uma taxa de metalização baixa e que portanto requer redução, uma fonte de ferro que possui um grau de metalização alto e que portanto requer apenas fusão, e um combustível sólido, e soprar um gás contendo oxigênio a uma temperatura comum ou maior, até 600°c, para dentro do forno, através de ventaneiras, apra reduzir e fundir as fontes de ferro. os valores ótimos de <sym>co (fator de utilização de gás) são determinados a partir do grau de metalização médio das fontes de ferro, e o forno de cuba é controlado de modo que o gás efluente a partir do forno possua os valores ótimos de <sym>co. o controle é realizado regulando a altura da carga, regulando a altura do leito de coque, e semelhantes, usando ventaneiras de múltiplos estágios, e dividindo radialmente a carga. conseqüentemente, as fontes de ferro podem ser eficientemente reduzidas e fundidas a uma taxa de combustível baixa.
