Carbothermic reduction of Electric Arc Furnace Dust via thermogravimetry
Ferreira, Felipe Buboltz; Flores, Bruno Deves; Osorio, Eduardo; Vilela, Antonio Cezar Faria (2018) [Artigo de periódico]Electric Arc Furnace Dust (EAFD) is a solid waste originated from electric steelmaking furnaces. Currently, according to some authors, there is an estimated generation of 15 to 25 kg of dust per ton of steel produced. The ... -
Combustibility and reactivity of coal blends and charcoal fines aiming use in ironmaking
Barbieri, Cláudia Caroline Teixeira; Osorio, Eduardo; Vilela, Antonio Cezar Faria (2016) [Artigo de periódico]Charcoal is a very important reducing agent in Brazil, the world’s largest steel industry based on charcoal blast furnace. Charcoal generates large amounts of charcoal fines during its production and processing. A good ... -
Design and construction of a PCI RIG for evaluation of pulverized fuels combustion : equipment features
Rech, Rene Lucio; Machado, André da Silveira; Barbieri, Cláudia Caroline Teixeira; Pohlmann, Juliana Gonçalves; Machado, Janaína Gonçalves Maria da Silva; Bagatini, Maurício Covcevich; Marcilio, Nilson Romeu; Peres, Antonio Eduardo Clark; Vilela, Antonio Cezar Faria; Osorio, Eduardo (2018) [Artigo de periódico]Pulverized coal injection (PCI) is a technique worldwide used in blast furnaces (BFs) to reduce coke consumption. Burning of pulverized coal injected into tuyeres of BFs takes place under medium pressure (up to 450 kPa), ... -
Estudo da relação entre as propriedades dos carvões e a microestrutura porosa dos coques
Agra, Anderson Azevedo; Flores, Bruno Deves; Nicolodi, Anderson; Silva, Guilherme Liziero Ruggio da; Vilela, Antonio Cezar Faria; Osorio, Eduardo (2019) [Artigo de periódico]A resistência mecânica do coque metalúrgico está intimamente relacionada com sua microestrutura porosa, de forma que o conhecimento quantitativo dos parâmetros microestruturais formada pelos diferentes tipos de carvões ... -
Evaluation of zinc removal and compressive strength of self-reducing pellets composed of Electric Arc Furnace Dust
Ferreira, Felipe Buboltz; Flores, Bruno Deves; Osorio, Eduardo; Vilela, Antonio Cezar Faria (2019) [Artigo de periódico]The amount of Electric Arc Furnace Dust (EAFD) is continuously increasing in mini-mill steel plants. This dust is considered a hazardous waste because of the presence of elements like lead, cadmium and chromium. Among many ... -
Influência das composições química e mineralógica de cinzas de misturas de carvões para PCI no comportamento de fusibilidade e viscosidade a altas temperaturas
Ghiggi, Maria Luisa Formoso; Osorio, Eduardo; Vilela, Antonio Cezar Faria; Barros, Ricardo Jose Tauffer; Cruz Júnior, Roberto da (2012) [Artigo de periódico]As causas da deterioração da permeabilidade da carga no alto-forno sob taxas altas de injeção de carvão pulverizado ainda não são bem conhecidas. Sabe-se na prática operacional que variações na qualidade das cinzas dos ... -
Quantificação por DRX dos componentes carbonosos presentes no pó de balão do alto-forno
Machado, André da Silveira; Mexias, Andre Sampaio; Vilela, Antonio Cezar Faria; Osorio, Eduardo (2011) [Artigo de periódico]A difração de raios X (DRX) é uma técnica padrão para caracterizar a estrutura cristalina dos materiais. Ela também pode ser utilizada para quantificar o tamanho dos cristalitos (Lc ) dos materiais carbonosos. Este trabalho ... -
Reactivity of brazilian coal, charcoal, imported coal and blends aiming to their injection into blast furnaces
Machado, Janaína Gonçalves Maria da Silva; Osorio, Eduardo; Vilela, Antonio Cezar Faria (2010) [Artigo de periódico]For about 10 years the steel industry in Brazil has used pulverized coal injection (PCI) technology in the blast furnaces based on imported coals. In order to decrease the dependence on imported coals, Brazilian coal, which ... -
Self-reducing pellets composed of wastes from steelmaking production for their recycling
Ferreira, Felipe Buboltz; Lima, Ana Rosa Rabelo de; Osorio, Eduardo; Vilela, Antonio Cezar Faria; Deike, Rüdiger (2022) [Artigo de periódico]This paper presents a study about the recycling of a mixture of EAF filter dust and mill scale; and slag, in the form of self-reducing pellets. At first, chemical and morphological characteristics of the material were ... -
