2. 1. Mineral Reactions and Slag Formation During Reduction of Olivine Blast Furnace Pellets

   Author : Elin Ryösä; Hans Annersten; Kyösti Heinänen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; olivine; iron ore pellets; blast furnace; reduction; alkali; coating; slag formation; Earth sciences; Geovetenskap;

   Abstract : The present work focuses on mineral reactions and slag formation of LKAB olivine iron ore pellets (MPBO) subjected to reducing conditions in the LKAB experimental blast furnace (EBF). The emphasis is on olivine reactions with surrounding iron oxides. Many factors influence the olivine behaviour. READ MORE

4. 2. Shrinkage and Related Properties of Alkali-Activated Binders Based on High MgO Blast Furnace Slag

   Author : Abeer Humad; Andrzej Cwirzen; John L. Provis; Karin Habermehl-Cwirzen; Andrzej Garbacz; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali-activated slag; alkali-activated materials; high-MgO blast furnace slag; shrinkage; creep; carbonation; strength; heat curing; Byggmaterial; Building Materials;

   Abstract : Concrete is the second most used material in the world just after water. A drawback is that it is mostly based on Portland cement, which has an extremely high carbon footprint reaching a staggering 900 kg/tonne. The carbon dioxide emissions related to the production of the Portland cement accounts for nearly 8 % of the global total. READ MORE

5. 3. Mechanical Properties of Residues as Unbound Road Materials - experimental tests on MSWI bottom ash, crushed concrete and blast furnace slag

   Author : Maria Arm; KTH; []
   Keywords : residues; unbound materials; MSWI bottom ash; crushedconcrete; blast furnace slag; mechanical properties;

   Abstract : For recycled aggregates and industrial by-products to beused correctly in road construction, it is necessary to knowtheir properties. Existing material specifications and testmethods for aggregates used in Sweden and in many othercountries are indirect and are based on empiricism. READ MORE

6. 4. Studies on High Alumina Blast Furnace Slags

   Author : Amitabh Shankar; Seshadri Seetharaman; Rob Boom; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : In the present work, viscosities and sulphide capacities of high alumina blast furnace slags were investigated. The systems investigated were four component CaO-SiO2-MgO-Al2O3 quaternary system, CaO-SiO2-MgO-Al2O3-TiO2 and CaO-SiO2-MgO-Al2O3-CaF2 quinary systems. READ MORE

7. 5. Reactions in the Lower Part of the Blast Furnace with Focus on Silicon

   Author : Joel Gustavsson; Pär Jönsson; Leiv Kolbeinssen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blast furnace chemistry; ironmak ing; thermodynamics; silicon compounds; combustion; fuel injection; mass balance; slags; pig iron; gases; droplets;

   Abstract : The thermodynamic conditions for the behaviour of silicon in the lower part of the blast furnace have been the focus of the thesis. More specifically, the influences of temperature, carbon activity, total gas pressure and Fe reoxidation on silicon have been studied. READ MORE
