| Abstract: | In a confocal scanning laser microscope, interactions between exogenous and endogenous inclusions on steel melts have been investigated. Higher capillary long-range attraction forces as well as higher acting lengths of the capillary forces between exogenous and endogenous particle pairs have been observed in comparison to endogenous inclusions pairs. The contribution of the roughness of the exogenous inclusions to the capillary attraction forces has been discussed and a surface filter design for a higher filtration efficiency of steel melts has been proposed. |
