A system for casting a length of a pole of a tubular shape with molten metal. The system comprises a crucible for containing the molten metal; a pouring spout fluidly connected to the crucible; and a plunger for plunging in the crucible to increase level of the molten metal in the crucible and thereby forcing a flow of the molten metal from the crucible to the pouring spout. The system further comprises a casting ring for receiving the molten metal poured out of the pouring spout; a motor for rotating the casting ring; a cooling assembly for cooling the molten metal; and a pulling assembly for pulling the pole out of and away from the casting ring as the molten metal solidifies.

A method for producing cast items in a casting method, wherein a charge of a conductive material is introduced into the sphere of influence of at least one alternating electromagnetic field, so that the charge is kept in a levitating state. The melt is poured into moulds in order to produce turbine blades, prostheses or turbocharger impellers.

A centrifugal casting apparatus for different materials may include a mold having a shape corresponding to a shape of an outer surface of a casting to be produced, and having a cavity receiving molten metals therein, a molten metal guide inserted into the mold and configured to guide the molten metals so that the molten metals are separately injected into the mold, a guide fixing support fixing the molten metal guide to a predetermined position, and a motor configured to rotate the mold around a rotation axis.

A casting mold supporting structure is provided herein which includes a support roller for supporting a part of a casting mold that is used in centrifugal casting. The casting mold has a supported surface (that is, a side surface of an end portion of the casting mold which end portion has a circular truncated cone shape) at which the casting mold is supported by the support roller. The supported surface is inclined with respect to a rotation axis of the casting mold.

A method of manufacturing a cylinder liner for an engine block for a vehicle propulsion system and the cylinder liner made from the method. The method includes providing a cylinder liner mold having a cylindrical inner surface, masking a first portion of the cylindrical inner surface, applying a coating to a second portion of the cylindrical inner surface, and forming a cylinder liner by solidifying molten metal in the cylinder liner mold.

A water-cooled centrifugal pipe casting machine includes a sector ladle tilting system, a pouring runner, a pipe mold and a pipe removing device. The pipe mold is provided to a travel system, and rotation of the pipe mold is controlled by a pipe mold rotating system. By using a servo motor driving the sector ladle tilting system, by using a parallel four-bar linkage structure tilting a sector ladle, and by using a variable frequency motor controlling the movements of a rack and a gear of a travel driving system, a constant amount of hot metal flowing out of the sector ladle per unit time can be ensured and a constant traveling speed of the centrifugal pipe casting machine are achieved. As such, uniformity of the wall thickness of the casting pipes can be ensured, the quality thereof can be improved, and materials required can be saved.

The invention relates to a method of producing elongate metal strands or fibres with a crucible, the method comprising the steps of; directing molten metal through a nozzle having a nozzle direction in a deposition direction at a regulated pressure difference between the inside and the outside of the crucible; depositing said molten metal from said nozzle on a rotating planar surface having an axis of rotation; entraining said molten metal in one plane via said rotating planar surface to form elongate metal strands, wherein said rotating surface is aligned at an alignment angle, to the deposition direction during the entraining of the molten metal; cooling said elongate metal strands to form solidified metal strands; and guiding said metal strands to collecting means to collect the solidified metal strands formed on the rotating planar surface.

The invention relates to a method for the treatment of an alloy based on titanium aluminide. The method comprises the following steps, during which no hot isostatic pressing is carried out: obtaining a semi-finished product (7) produced by centrifugal casting, then heat treating the semi-finished product in order to obtain an alloy microstructure comprising gamma grains and/or lamella grains (alpha2/gamma).
