A wear member includes a first leg, a second leg, and a throat portion connecting the first leg to the second leg. The first leg defines a first leg thickness, and the throat portion defines a throat portion thickness disposed adjacent to the first leg thickness. A ratio of the throat portion thickness to the first leg thickness ranges from 1.1 to 1.2.

A molten metal filtration apparatus is provided. The apparatus includes 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 having an open cell structure characterized by a plurality of interconnected voids. The filter element partitions the filter chamber. At least one heater device is provided at an elevation within the filtration chamber that is equal to or below the filter element.

The present invention relates to the use of closed-pore microspheres of expanded perlite as a filler for producing moldings for the foundry industry, to a composition for producing moldings for the foundry industry, comprising closed-pore microspheres of expanded perlite as a filler, and a binder, the binder being selected from the group consisting of water glass, phenol-formaldehyde resins, two-component systems comprising as reactants a polyisocyanate and a polyol component containing free hydroxyl groups (OH groups), and starch, and also to moldings for the foundry industry and to a process for producing a molding for the foundry industry.

The invention relates to a single-piece feeder body for use as a component of a two-part or multi-part telescopic feeder insert in metal casting,

having a feeder wall which at least partially delimits a feeder cavity for receiving liquid metal, wherein the feeder wall has a passage opening for the liquid metal into the feeder cavity, and an outer surface on which there are arranged at least one outwardly projecting holding element and at least one guide part with a sliding section for a feeder element which corresponds with the feeder body,
wherein the guide part has a supporting section which protrudes outwardly on the outer surface and which, adjoining the sliding section of the guide part for guiding the feeder element, extends in the direction of the passage opening.

A casting apparatus for producing a casting by pouring a metal melt into a gas-permeable casting mold by gravity, comprising: a gas-permeable casting mold comprising a cavity including a sprue composed of a tubular portion and a cup portion having a larger diameter than that of the tubular portion to receive the metal melt, a runner constituting a flow path of the metal melt supplied through the sprue, and a product-forming cavity to be filled with the metal melt sent through the runner; a means for pouring the metal melt into the sprue by gravity; a gas-blowing unit comprising a gas-ejecting member to be connected to the sprue; and a mechanism for moving the gas-ejecting member; the gas-ejecting-member-moving mechanism placing the gas-ejecting member at a position just above the tubular portion and not interfering with gravity pouring of the metal melt, and moving it downward for connection to the tubular portion; the gas-blowing unit having blowing a gas to fill the product-forming cavity with the metal melt.
