摘要： The present invention provides a method which is capable of more strictly controlling the oxygen partial pressure required during the melting of a starting material, thereby being capable of recovering a valuable metal more efficiently. A method for recovering valuable metals (Cu, Ni, Co), said method comprising the following steps: a step for preparing, as a starting material, a charge that contains at least phosphorus (P), manganese (Mn) and valuable metals; a step for heating and melting the starting material into a melt, and subsequently forming the melt into a molten material that contains an alloy and slag; and a step for recovering the alloy that contains valuable metals by separating the slag from the molten material. With respect to this method for recovering valuable metals, the oxygen partial pressure in the melt is directly measured with use of an oxygen analyzer when the starting material is heated and melted.

摘要： A method of charging a pre-packaged charge in a metallurgical or refining furnace includes providing a disposable metal container having at least one attachment member and forming a pre-packaged charge by loading scrap material into the metal container. The method also includes releasably coupling the at least one attachment member of the container to a lifting device, and then de-coupling the pre-packaged charge from the lifting device so that the combination of the scrap material and the disposable metal container are charged in the furnace.

摘要： A defective engine block recycling method in a continuous casting line includes inserting a bore pin into an engine block mold, fitting a real liner to an outer circumferential surface of the bore pin, and injecting molten aluminum into the engine block mold to cast an engine block body. If an abnormality is generated in the engine block mold or the molten aluminum and if a defect is expected to generate in the engine block body, a defective engine block unit is produced by fitting a dummy liner, which is made of a material identical with or similar to a material of the engine block body, to the bore pin. The defective engine block unit thus produced is directly melted and recycled.

摘要： A coupling has an opening and a protrusion extending downward from the opening. The protrusion has threads that are preferably positioned outside of the opening. A rotor shaft that connects to the coupling has an internal bore with threads that receives and retains the protrusion, such as by a threaded connection between the two, so the protrusion applies driving force to the shaft.
