Abstract

PROCESSO DE INJEçãO DE BORRACHA GRANULADA NOS ALTOS FORNOS trata-se de um processo que parte da utilização de produtos da borracha como combustível termorredutor, via injeção pelas ventaneiras em Altos Fornos, este em substituição aos combustíveis sólidos tradicionais usados, como o coque, carvão mineral e antracito, favorecendo assim o processo de reciclagem e diminuição da emissão de gases nocivos à saúde.
