Electromagnetic stirring device in a mould for casting aluminium or aluminium alloys, wherein the electromagnetic stirring device has a winding core of conductive coils intended for the circulation of a current generating an electromagnetic field of stirring of the molten metal inside the mould. A mould, casting machine and casting plant provided with such an electromagnetic stirring device are also provided. A stirring method in a mould for casting aluminium or aluminium alloys is disclosed, including a phase of supply of phase-shifted currents on an electromagnetic stirring device in a mould.

High quality titanium ingot is produced by using recovered titanium scrap as a raw material and adding additives. Scrap, each having individual information of identification and process profile information, is passed through automatic reading means to obtain the information and to store it in a data server. A calculating means calculates a combination of the scrap, titanium sponge and additives and feed rate of each of them so as to satisfy chemical composition and producing rate of a target ingot product using the individual identification pieces of information stored in the data server, during a beginning step of the ingot production, and transmits electrical signals corresponding to calculated results of the combination and the feed rates from the calculating means to a feed rate controlling means of each feed means of the titanium scrap, titanium sponge, and additives and then starting supply of them, and detecting means equipped at an extracting part of the ingot product reads actual producing rate of the ingot product, after the beginning step of the ingot production. The calculating means controls feed rate of the titanium scrap, titanium sponge, and/or additives based on the actual producing rate.

A process for producing metal ingots includes the steps of: a) filling at least one ingot mould at a filling temperature with at least one metal charge in the solid state, which has a melting temperature higher than ambient temperature, b) melting the metal charge by heating the ingot mould to a heating temperature higher than or equal to the melting temperature of the metal charge, c) solidifying the molten metal charge into an ingot by cooling the ingot mould to a cooling temperature lower than the melting temperature of the metal charge and higher than the ambient temperature, d) extracting the ingot from the ingot mould at an extraction temperature, and e) repeating steps a) to d). At steady state, both the filling temperature and the extraction temperature are lower than or equal to the cooling temperature and higher than the ambient temperature.

An enclosure having a sealing device, for a casting installation, having a first body and a second body that is removably joined to the first body along a bearing axis, the first and second bodies together delimiting an internal chamber. The sealing device comprises: at least one compression member, at least one seal having a lateral contact face extending substantially parallel to the bearing axis; the compression member and the seal being arranged with respect to one another such that the compression member is in contact with the lateral contact face of the seal and exerts a compression force thereon that is oriented orthogonally to the bearing axis.

An apparatus for continuous or semi-continuous low pressure casting of metal, in particular directly-cooled (DC) casting of extended objects such as a rods, bars or billets of aluminium. The apparatus includes a frame construction with at least one chill or mould having a mould cavity that is provided with an upwardly open inlet and an outlet with cooling means. The inlet of the mould is connected to a distribution chamber receiving liquid metal from a metal store such as a holding furnace via a metal supply channel or launder. A flexible launder section is provided between the launder and the metal distribution chamber whereby the frame construction with the moulds and distribution chamber can be raised and lowered to enable complete filling of metal to the moulds. Subsequently it is possible to control the metal level in each respective mould cavity in relation to the metal level in the launder and thereby controlling the low pressure casting.

A system and method for sensing the position of an ingot within a segmented mold of a vacuum metallurgical system. An inductive sensory system measures the variations in current between a power source and load of an induction heating coil. The system and method is particularly suitable for determining the position of an ingot within a melting system mold where the mold has a relatively reduced or small cross-sectional area.
