Abstract

método para fabricação de materiais de sinterização. a presente invenção refere-se a um método para fabricação de materiais de sinterização é proporcionado, no qual calcário em pó ultrafino ou ainda um pó com alto teor de carbono são eficazmente usados no tratamento do revestimento exterior para a superfície de partículas granuladas com um material em pó com base em calcário e um material combustível sólido em pó, pelo que a produtividade é aprimorada em comparação com o nível convencional. um minério de ferro e um material contendo sio~ 2~ são peletizados em partículas granuladas e a superfície das partículas granuladas é revestida fornecendo um material em pó com base em calcário para formar uma camada interna do material em pó com base em calcário para formar uma camada interna do material em pó com base em calcário e, subsequentemente, fornecendo um material combustível sólido em pó formar uma camada externa do material combustível sólido em pó sobre a camada interna do material em pó com base em calcário. o material em pó com base em calcário contém em pó ultrafino a 5 a 40% em massa e o material combustível sólido em pó contém um pó com alto teor de carbono a 5 a 40% em massa.method for manufacturing sintering materials. The present invention relates to a method for manufacturing sintering materials which is provided, in which ultrafine limestone powder or a high carbon powder is effectively used in the treatment of the outer coating for the surface of granulated particles with a material. limestone-based powder and a solid combustible powder material, so productivity is improved compared to the conventional level. an iron ore and a sodium-2-containing material are pelletized to granulated particles and the surface of the granulated particles is coated providing a limestone based powder material to form an inner layer of the limestone based powder material to form a inner layer of limestone-based powder material and subsequently providing a solid powdered combustible material to form an outer layer of solid powdery combustible material on the inner layer of limestone-based powdery material. limestone based powder material contains 5 to 40 wt% ultrafine powder and solid fuel combustible powder contains 5 to 40 wt% high carbon powder.
