A casting method includes forming a seed. The seed has a first end and a second end and an inner diameter (ID) surface and an outer diameter (OD) surface. The seed second end is placed in contact or spaced facing relation with a chill plate. The first end is contacted with molten material. The molten material is cooled and solidified so that a crystalline structure of the seed propagates into the solidifying material. At least a portion of the seed contacted with the molten material has a solidus higher than a solidus of at least an initial pour portion of the molten material.

Disclosed are a high-boron high-vanadium high-speed steel and a method for preparing the same. Pig iron, scrap steel, ferrochromium, ferromanganese, ferroboron, ferrovanadium, industrial pure iron, ferromolybdenum, ferrotungsten, ferrosilicon and ferrotitanium are subjected to smelting at 1580-1600° C. and refining to obtain a liquid steel. The liquid steel is subjected to superheating, and directional solidification at a casting temperature of 1420-1430° C., and cooled to room temperature to obtain the directionally solidified high-speed steel.

A method of forming a directionally-solidified casting component using a casting system is provided. The casting system includes a chamber having a heating zone and a cooling zone separated by a baffle plate. The method includes pouring an alloy in a liquid state into a mold shell. The mold shell is positioned on a chill plate within the heating zone. The method further includes moving the mold shell from the heating zone into the cooling zone. The alloy transfers from the liquid state to a solid state within the mold shell while moving the mold shell from the heating zone to the cooling zone. The method further includes contacting the mold shell with a heat transfer member.

The application belongs to the technical field of a casting mold and provides a side mold and a low-pressure hub casting mold. Channels of a cooling loop are processed in a back cavity of a side mold frame, a distance between the channels along a solidification direction of a casting gradually increases, and a cooling medium flows along the cooling loop, the ability of taking away heat changes from strong to weak, and a larger temperature gradient of the side mold may be formed by superposition with a temperature gradient formed by the thickness of the side mold.

A method of casting a metal alloy ingot, including the following steps: providing a one side open-ended mould including a plurality of sides and a bottom plate defining a mould cavity with a mould opening, the open-ended mould being pivotable around a horizontal rotational axis between a position so that the mould opening points upwards and a position so that the mould opening points side-wards or down-wards; positioning the open-ended mould such that the mould opening points side-wards or down-wards; providing a casting container with an upwardly positioned aperture; filling the casting container with molten metal for one casting operation; coupling the casting container to the open-ended mould so that the casting container is located below the mould while the mould opening points side-wards or down-wards; rotating the open-ended mould together with the casting container around the horizontal rotational axis for approximately 90° to 180° from a position whereby the mould opening points side-wards or down-wards to a position whereby the mould opening points upwards such that the molten metal is conveyed through the mould opening into the open-ended mould until reaching a desired thickness, whereby the molten metal in the open-ended mould is cooled directionally through its thickness where the solidification front remains substantially monoaxial.

A method for casting aluminum on a rotor, comprising: installing casting equipment on a casting workbench and storing enough molten aluminum in the casting equipment, wherein the casting equipment comprises an heat preserving furnace and an electromagnetic pump arranged at a side of the heat preserving furnace; assembling a plurality of rotor iron cores with a plurality of dies respectively and preheating outside the casting workbench; installing the plurality of preheated dies on a plurality of liquid outlet gates at a top end of the electromagnetic pump, wherein each liquid outlet gate is matched with a liquid inlet gate of the dies; heating and keeping the installed die in a multi-stage heating mode; controlling the pressurizing pressure of the electromagnetic pump in time-period when the electromagnetic pump is used for casting; and after completing casting, moving the plurality of dies out of the casting workbench to be cooled. According to the method for casting aluminum through the rotor, the casting efficiency is improved by reasonably distributing the heating time and the one-time multi-casting mode; the top-down temperature gradient is matched with accurate pressure control, so that the compensation capacity is improved.

A method of manufacturing a wing element that is provided inside a gas turbine and through which a fluid passes and a method of manufacturing a blade are provided. The method of manufacturing the wing element includes preforming the wing element; disposing the wing element inside a mold; sequentially melting the wing element inside the mold along one direction using a heating device; and solidifying the melted wing element using a cooling device.

A casting mold (260) comprises a shell (262) extending from a lower end (264) to an upper end (266) and having: an interior space (280) for casting metal; and an opening (268) for receiving metal to be cast. A plurality of thermocouples (900) are vertically-spaced from each other on the shell.

An apparatus for casting a part that includes a first housing, a second housing, a handling system and a cooling apparatus. The first housing defines a first chamber. The first chamber is configured to receive a melt heater and a mold heater. The second housing is configured to move between a first position and a second position such that when the second housing is in the first position, the first housing is open such that a mold can be inserted therein and when the second housing is in the second position, the second housing and the first housing define a second chamber. The cooling apparatus is configured to be positioned within the second chamber.

A method for casting a part, that includes the steps of: introducing a mold into a first housing; engaging the first housing with a second housing to define a second chamber; melting an ingot within the furnace; reducing pressure within the second chamber to a first predetermined pressure; pouring at least a portion of the melted ingot into the mold; adding an gas to the second chamber to raise the pressure to a second predetermined pressure; moving the mold such that it is engaged with the means for cooling; and solidifying the liquid metal within the mold.
