Abstract
A molten metal filter box. The filter box includes a filter housing provided in a flow path for molten metal. A horizontal partition is disposed within the filter housing and has at least one filter receiving passage. A filter medium in the shape of a substantially flat plate is positioned within the filter receiving passage and below an inflow path of the molten metal. The filter medium includes a hole. A filter handling tool is disposed within the hole. The filter handling tool can optionally include a handle secured to the molten metal filter box to suspend the filter medium. Advantageously, the filter medium can be removed by grasping the filter handling tool and removing the filter medium.
