According to another embodiment, a molten metal filter having two opposed plates is provided. At least one hollow elongated member comprised of a porous refractory material is attached at a first end to a first end plate and at a second end to a second end plate. The first end plate has a passage extending through a width of the first end plate and a ledge that receives the first end of the elongated member. The second end plate has an opening receiving the second end of the elongated member. The opening passes through the width of the second end plate and is dimensioned to be larger than a circumference of the elongated member.

An apparatus and method for filtering molten metal (M), such as aluminum or an aluminum alloy includes at least one ceramic foam filter or any other type of filtration media such as porous tube or alumina balls disposed in a receptacle (12) for the molten metal (M). A vibrator vibrates at least one of the filter, the receptacle (12) or the metal and may be used to induce priming, filtering and/or drainage of the filter. The vibrator may be retrofitted to an existing filter system and may be adjustable in frequency and amplitude. The vibration may be continuous over a given period or produced in a single shock.

This filtration device 10 has a can body 20 having a reservoir 3 that connects to an opening 9 at the top, and a filtration unit 40 which is detachably installed in the reservoir. The filtration unit has a support plate 42, and filtration tubes 41 of bottomed cylindrical shape fastened to the support plate. The side wall 22 of the can body 20 has a protruding locking part 30 for installation of the filtration unit so that the filtration tubes are suspended from the support plate 42, with the openings 43 thereof facing upward. With the support plate 42 locked into the locking part 30, pressing members 70 for pressing the support plate 42 downward from the upper surface side in sections thereof lying towards the peripheral edge S in relation to the fastening locations of the filtration tubes 41 are deployed, making it possible for the support plate 42 to be fastened in clamped fashion by the locking part 30 and the pressing members 70.

Described are high pressure filter housings and apparatuses that are useful to contain a fluid under high pressure, with example housings including first and second pieces having complimentary tapered joint surfaces that can form a fluid-tight seal without a gasket located between the surfaces, and methods of making and using the high pressure filter apparatuses.

A Filter module of a filtering system for a tundish is provided that includes a filter unit provided with channels extending from a channel inlet to a channel outlet, and a wall module with a wall defining an opening extending over an opening height from the floor. A bypass passage is defined between the wall module and the filter module of largest width such that a metal melt can only flow from the inlet portion to the outlet portion by flowing either through the channels of the filter unit or through the bypass passage. The wall module includes a wall ledge having a width. The filter module further includes a filter ledge having a width and being offset vertically relative to the wall ledge to form therewith a baffle.

A vibrator vibrates at least one of the filter, the receptacle (12) or the metal and may be used to induce priming, filtering and/or drainage of the filter. The vibrator may be retrofitted to an existing filter system and may be adjustable in frequency and amplitude. The vibration may be continuous over a given period or produced in a single shock.

Methods for removing sludge and/or impurities from a molten metal are disclosed herein, as well as sludge removal devices and systems for use in the methods. Sludge removal devices that can reduce the downstream deposition of sludge in certain process components through upstream deposition and subsequent removal from the molten metal are also disclosed.

A method of transferring molten metal to a die casting mold is disclosed. The method includes providing a ladle with a dip well and a dispensing nozzle having a fluid metal filter formed therein as well as providing a receptacle fluidly between the ladle and the mold. Further the method includes delivering the molten metal from the ladle to the receptacle by positioning an exit face of the dispensing nozzle over the receptacle and rotating the ladle such that the exit face of the dispensing nozzle is repositioned proximal the bottom of the receptacle and conveying the molten metal that has been delivered to the receptacle into a mold cavity that is placed in fluid communication therewith.

Provided are a silica ceramic material, a ceramic foam filter, and a preparation method and use of the ceramic foam filter. The silica ceramic material includes a ceramic powder and an auxiliary material, where the ceramic powder includes the following components by mass percentage: 40% to 80% of silica, 8% to 30% of alumina, and 8% to 30% of silicon carbide; and the auxiliary material includes a binder and a dispersing agent: a mass of the binder accounts for 1% to 5% of a mass of the ceramic powder, and a mass of the dispersing agent accounts for 0.5% to 1% of the mass of the ceramic powder.

An embodiment relates to a mesh net supply apparatus mesh net supply apparatus for supplying mesh nets adapted to remove foreign substances upon the injection of a molten material to a casting mold, including: a first table for placing the mesh nets multi-stacked on top of one another on a plurality of positions thereof; an upper table having a mesh net through hole; a gripping unit for gripping the mesh net exposed from the mesh net through hole; an elevating unit for moving the gripping unit upwards and downwards; a shuttle unit for transferring the gripping unit and the elevating unit; and a plurality of separation plates locked onto the periphery of the mesh net so that the periphery of the mesh net is elastically bent and lifted upwards.
