:The flowing process of filtered and unfiltered molten metal was investigated through hydraulic simulation. The equations for pressure loss was established according to hydraulics and mathematic deduction. The pressure loss model obtained can be used to predict the flow velocity and filling time of molten metal, and also can be used as a guidance when adapting ceramic filters for a casting system......
