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 system and method for transferring molten metal from a vessel and into one or more of a ladle, ingot mold, launder, feed die cast machine or other structure is disclosed. The system includes at least a vessel for containing molten metal, an overflow (or dividing) wall, and a device or structure, such as a molten metal pump, for generating a stream of molten metal. The dividing wall divides the vessel into a first chamber and a second chamber, wherein part of the second chamber has a height H2. The device for generating a stream of molten metal, which is preferably a molten metal pump, is preferably positioned in the first chamber. When the device operates, it generates a stream of molten metal from the first chamber and into the second chamber. When the level of molten metal in the second chamber exceeds H2, molten metal flows out of the vessel and into another structure, such as into one or more ladles and/or one or more launders.

Provided is a hot-forged 6xxx-series aluminum alloy having excellent corrosion resistance and still having both high strength and good ductility. A forged 6xxx-series aluminum alloy having a specific chemical composition after solution treatment is further subjected to warm working to introduce dislocations into the forged aluminum alloy microstructure. This allows the forged aluminum alloy after artificial aging to have a microstructure which has a high dislocation density, includes a large proportion of small angle grain boundaries, and has a high average number density of precipitates. Thus, the resulting forged aluminum alloy has a 0.2% yield strength of 400 MPa or more and an elongation of 10% or more and combines properties necessary for suspension parts.
