Akademisk avhandling som med tillstånd av KTH i Stockholm, framlägges till offentlig granskning för avläggande av Teknisk Doktorsexamen, tisdagen den 20 december kl. iii To my beloved parents iv v Abstract This study focuses on two different types of micro-particles selected from different stages off iron and steelmaking processes. These particles are dust particles generated due to mechanical ...

Iron ore pellets are small and hard spherical particles agglomerated from a fine iron concentrate. They used in the blast furnace process to produce hot metal. The diameter of is usually between 8 16 mm. In this study, batch magnesia was first sieved into particle sizes 8–10 mm, 10–12.7 12.7–16 mm 16–20 four different size fractions were study effect pellet on metallurgical properties. experime...

In general terms, sintering describes the bonding of particles into a more coherent structure, where joins form between packed particles, usually as a result of heating. Characterization of sintering is an important topic in the fields of metallurgy, steel, iron ore pellets, ceramics, and snow for understanding material properties and material strength. Characterization using image analysis has...

Size measurement of iron ore pellets in industry is usually performed by manual sampling and sieving techniques. The manual sampling is performed infrequently and is inconsistent, invasive and time-consuming. Iron ore pellet’s sizes are critical to the efficiency of the blast furnace process in the production of steel. Overly coarse pellets affect the blast furnace process negatively, however t...
