Abstract

método para fabricar ferro reduzido direto (dri) processado, e, material de ferro reduzido direto (dri) processado. um material de dri processado tendo uma aspereza de superfície média (ra) menor do que 1,5 <109>m é divulgado. um método e sistema para fabricar o dri processado também são divulgados. uma forma de realização do método e sistema podem incluir a montagem de uma câmara rotacionável tendo uma tela interna capaz de suportar dri durante a rotação, com pelo menos uam abertura na câmara para permitir que os produtos finos saiam da câmara durante a rotação e liberação de dri na câmara para girar o dri na tela para remover os produtos finos do dri. uma outra forma de realização do método e sistema podem incluir montagem de uma câmara rotacionável tendo uma extremidade de alimentação e uma extremidade de saída tendo uam tela neste capaz de suportar dri quando o dri moves através da câmara e liberação de dri á câmara e rotacionar a câmara para girar o dri enquanto remove-se os produtos finos.
