Demir cevheri peletlemesinde kolemanitin organik bağlayıcı ile birlikte kullanılması

Use of boron based binders in pelletization of iron ores Sivrikaya, Osman; Arol, Ali İhsan; Department of Mining Engineering (2011) Bentonite is the most preferred silicate-based binder in iron ore pelletizing. However, it is considered as an impurity due to its high SiO2 and Al2O3 content. The iron-making economy is adversely affected by the addition of bentonite or other silicate-based binders. In recent years, impurity-free alternative binders have been tested in order to replace bentonite or to lower the bentonite dosage. Organic binders yield good quality green and dry pellets. However, they fail to impart enough mechanical strengt...
Heat treatment of iron ore agglomerates with microwave energy Çırpar, Çiğdem; Arol, Ali İhsan; Department of Mining Engineering (2005) Pelletizing is a size enlargement technique employed to process fine-grained iron-bearing concentrates and powder ores. Mechanical strength of fired pellets is important for handling. When the pellets undergo metallurgical processing, their mechanical strength is a measure of their resistance to degradation by breakage due to impacts and abrasion to which they are exposed in the upper part of the blast furnace. In this study, heat treatment of iron ore agglomerates with microwave energy is investigated. Fir...
Synthesis and characterization of bulk glass-forming iron-boron based alloy systems Gürbüz, Selen Nimet; Akdeniz, Mahmut Vedat; Department of Metallurgical and Materials Engineering (2004) The aim of this study, which was carried out in two main parts, is to investigate the glass forming ability of Fe-based systems. The first part involves the theoretical modeling to cover the requirement of a predictive model to identify the Fe-based alloy families that have high glass forming ability in the frame of atomistic and thermodynamic approach. The second part involves the experimental investigations to prove the results of the conducted theoretical modeling studies. For this purpose, in the first ...
Investigation of solidification and crystallization of iron based bulk amorphous alloys Erdiller, Emrah Salim; Akdeniz, Mahmut Vedat; Department of Metallurgical and Materials Engineering (2004) The aim of this study is to form a theoretical model for simulation of glass forming ability of Fe ? Based bulk amorphous alloys, to synthesize Fe ? based multicomponent glassy alloys by using the predictions of the theoretical study, and to analyze the influence of crystallization and solidification kinetics on the microstructural features of this amorphous alloys. For this purpose, first, glass forming ability of Fe ? (Mo, B, Cr, Nb, C) ? X ( X = various alloying elements, selected from the periodic table...
Nano-scale phase separation and glass forming ability of iron-boron based metallic glasses Aykol, Muratahan; Akdeniz, Mahmut Vedat; Department of Metallurgical and Materials Engineering (2008) This study is pertinent to setting a connection between glass forming ability (GFA) and topology of Fe-B based metallic glasses by combining intimate investigations on spatial atomic arrangements conducted via solid computer simulations with experimentations on high GFA bulk metallic glasses. In order to construct a theoretical framework, the nano-scale phase separation encountered in metallic glasses is investigated for amorphous Fe80B20 and Fe83B17 alloys via Monte Carlo equilibration and reverse Monte Ca...
