Abstract

SISTEMA DE CARREGAMENTO PRESSURIZADO PARA ALTO FORNO. Compreende o presente certificado de adição a patente n<0> PI-050 1206-6 depositada em 08/03/2005, a uma visão mais detalhada do sistema e dos aparelhos envolvidos, que não foram previstos no sistema de carregamento para Altos Fornos siderúrgicos ou qualquer forno, que necessite ou no qual se deseje efetuar o carregamento pressurizado, de materiais sólidos que possam ser transportados em transportadores de correia convencionais, em transportadores de correia tubulares ou em transportadores do tipo esteiras, quando a inclinação necessária é maior que a permitida para transportadores de correias convencionais ou tubulares, objeto da referida patente. Representando a adoção de válvulas rotativas (71, 72, 73, 74, 75 e 76), acrescentadas para propiciar uma maior perda de carga no sistema, possibilitando assim um menor consumo de nitrogênio para manter a pressão do alto forno no nível desejado. Sendo utilizado, também o nitrogênio e o GAF em substituição ao ar comprimido e ao nitrogênio, respectivamente, previstos na patente original.HIGH OVEN PRESSURED CHARGING SYSTEM. This certificate of addition comprises patent nr. PI-050 1206-6 filed on 08/03/2005, a more detailed view of the system and apparatus involved, which were not foreseen in the loading system for blast furnaces. or any furnace requiring or desiring pressurized loading of solid materials which may be carried on conventional belt conveyors, tubular belt conveyors or crawler type conveyors when the required inclination is greater than permitted for conventional or tubular belt conveyors, object of said patent. Representing the adoption of rotary valves (71, 72, 73, 74, 75 and 76), added to provide a greater pressure drop in the system, thus allowing a lower nitrogen consumption to keep the blast furnace pressure at the desired level. Being used also nitrogen and GAF to replace compressed air and nitrogen, respectively, provided for in the original patent.
