摘要： Fully dense long ingots are produced by the bottom pouring method and apparatus of the present invention. A solidification sequence is achieved which is conducive to eliminating solidification shrinkage and piping. The set-up of the bottom poured ingot molds facilitates a solidification sequence starting from the top and then down the ingot mold and then up the down pour pipe.

摘要： This invention relates to an improved process for casting a metal by pouring molten metal into and around a mold assembly, where a riser is a component of the mold assembly. The process comprises (a) inserting a riser insert into the cavity of the riser, and (b) then allowing molten metal to flow into the cavity of the riser containing the riser insert. The process is carried out in a manner such that the density and the shape of the riser insert enables the riser insert to float on the surface of the molten metal when the molten metal enters the cavity of the riser.

摘要： The method of casting of the present invention is capable of making volume of a feeder head can be small and making cooling rate of the feeder head can be easily made lower than that of a cavity. The method is executed in a casting machine, which includes a casting die, in which the feeder head is provided between a metal inlet and the cavity and in which heat insulating of the feeder head is greater than that of the cavity so as to make cooling rate of the feeder head lower than that of the cavity. The method comprises the steps of: pouring a molten metal into the cavity; reacting the molten metal on a deoxidizing compound in the cavity so as to deoxidize an oxide film formed on a surface of the molten metal; and supplementing the molten metal in the feeder head to the cavity when the molten metal in the cavity is solidified and shrinked.

摘要： A feeder insert is provided for a mold utilized for pouring metal. The insert includes a feeder body having a feed volume, in the form of an inner space, delimited by side walls and a top portion. A feed opening is provided in the base region for communicating with a hollow mold space. A domed feeder cap is displaceably disposed on a feeder body, surrounds the side walls of the feeder body to form an insulating gap, and is fixed in position relative to the feeder body prior to molding of the insert. At least one spacer of flexible material is disposed between the top portions of the feeder body and feeder cap such that during molding of the insert, and placement of the feeder body on the mold surface, due to molding pressure that occurs the feeder cap is displaceable relative to the feeder body while leaving an insulating gap between the top portions of the feeder body and feeder cap.

摘要： A method of casting an object, usually a railroad wheel, is provided. A graphite mold having a drag section and a cope section requires a plurality of riser openings in the cope section to ensure proper dimensional accuracy of the cast railroad wheel by allowing molten metal to continue to feed downwardly through the riser openings to the cast wheel cavity during initial cooling. The riser openings are lined with an improved insulating material in an accurate manner such that the insulating material is added between a machined riser opening in the graphite cope mold section and a mandrel inserted in the riser opening.
