Influence of ceramic filtrers on metal streaming in running systems
 Vymyslický, Jakub ; Láník, Boris (referee) ; Roučka, Jaromír (advisor)
This thesis deals with influence of ceramic filters on metal streaming in running systems. The purpose of this thesis is to investigate the influence of porosity, thickness of ceramic filters and also viscocity of molten metal on mold filling. Hydraulic resistance of ceramic filters and possibility of its use in numeric simulation is also tested. At the beginning of the thesis there is theoretic analysis of filtration which inlcudes inclusions in cast irons, filtration matters, gatting systems design, hydraulic resistance and numeric simulation. The second experimental part of this thesis is focused on measuring shedding of molten grey cast iron and ductile iron through gatting systems with filters which are labelled VUKOPOR S. The experimental part then deals with evaluation of experiments results, calculation of hydraulic resistance and numeric simulation with the use of measured data.
