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.GRANULATED RUBBER INJECTION PROCESS IN HIGH OVEN is a process that starts from the use of rubber products as thermo-reducer fuel, through injection by blast furnaces, in substitution of the traditional solid fuels used, such as coke, mineral coal. and anthracite, thus favoring the recycling process and reducing the emission of gases harmful to health.
