Abstract

"PéLETES LIGADAS A FRIO, DE AUTO-REDUçãO". Péletes ligadas a frio, de auto-redução e um método para sua produção para fundir uma grande variedade de aços, incluindo fabricação de ferro em um alto forno, fabricação de ferro não em um alto forno e todos os tipos de fabricação de aço em fornos de fundição de aço, etc. Os péletes ligados a frio, de auto-redução compreendem concentrado de minério de ferro, um agente de redução carbonáceo e ligante de cimento Portland finamente dividido com requisitos especiais como um aglutinante. Os componentes são combinados juntos para formar uma mistura. Os péletes são produzidos quando a mistura é colocada em um disco de esferas ou tambor giratório e água é adicionada. Péletes com um tamanho predeterminado, normalmente oscilando de cerca de 8-16 mm, são obtidos usando peneiras de laminação. Os péletes são, então, continuamente colocados em um dispositivo de cura. Dentro do dispositivo de cura, os péletes, então, serão hidratados e carbonados através do uso de gases quentes contendo dióxido de carbono, com uma faixa de temperatura de cerca de 100-300<198>C. Após o que, após secagem, os péletes secos são descarregados do dispositivo de cura e estarão prontos para uso.
