Claims15
A molten metal filtration apparatus comprising a filter chamber having a floor, a metal inlet, a metal outlet, and a wall surface adapted to be partitioned by at least one filter element, said filter element having an open cell structure characterized by a plurality of interconnected voids, wherein the filter element partitions the filter chamber;
- and wherein at least one heater device is provided at an elevation within the filtration chamber that is equal to or below the filter element, and wherein at least one heater device is located in an outlet channel of the apparatus at an elevation below at least one filter element wherein the at least one heater device is positioned in a outlet channel of the apparatus at an elevation below the at least one filter element over an entire length of the at least one heater device.
A molten metal filtration apparatus comprising a filter chamber having a floor, a metal inlet, a metal outlet, and a wall surface adapted to be partitioned by a plurality of filter elements, said filter elements comprising filter tubes dispersed between end plates, said filter tubes having an open cell structure characterized by a plurality of interconnected voids, wherein the filter elements are oriented parallel and partition the filter chamber, said filter tubes being disposed in at least two rows and at least two columns, said rows and columns defining an open space, and wherein at least one heater device is positioned within said open space, and wherein at least one heater device is positioned in an outlet channel of the apparatus at an elevation below at least one of said filter elements wherein the at least one heater device is positioned in a outlet channel of the apparatus at an elevation below the at least one filter element over an entire length of the at least one heater device.
