Slag holdups in a fixed bed of carbonaceous particles were investigated using three-dimensional (3D) computational fluid dynamics (CFD) and discrete element method (DEM) simulations. In particular, the effect of improved wettability on the slag holdu

X-ray radiographic technique was applied to investigate the slag holdup in a fixed bed of SiC particles (8 to 9 mm) in a graphite crucible at 1773 K. With increasing temperature, liquid slag droplets started to drip through the bottom holes of the gr

In this study, the hyperthermia efficiency of CoFe2O4 nanoparticles (CFNPs) was enhanced by narrowing their size distribution and increasing their magnetic moment. The CFNPs were synthesized using the solvothermal reflux method. The NPs were crystall

In order to reduce ironmaking-related CO2 emissions, hydrogen-enriched blast furnace (BF) operation is currently under development. In hydrogen-enriched BF operation, coke layer thickness can be decreased to reduce CO2 emissions. However, BFs operati
