20080196550 | METHOD OF PRODUCING AN OXYGEN-FREE COPPER WIRE MATERIAL BY A CONTINUOUS CAST-ROLLING METHOD USING A ROTATIONAL MOVABLE MOLD - A method of producing an oxygen-free copper wire material, containing: continuously guiding a molten copper obtained by melting electric copper, into a tundish through a conduit; injecting the molten copper in the tundish, into a rotational movable mold; cooling and solidifying the molten copper, to form an ingot; and continuously drawing the ingot out of the mold, followed by continuous rolling; the method further containing: allowing the molten copper in the conduit to react with a solid reducing agent, under blowing an inert gas thereinto; allowing the molten copper in the tundish to react with a solid reducing agent, under blowing an inert gas thereinto; and adding a phosphorus compound to the molten copper, so that the phosphorus content in the ingot would be from 1 to 10 ppm; and controlling the temperature of the molten copper in the tundish from 1,085 to 1,100° C. | 08-21-2008 |
20100307712 | PROCESS AND EQUIPMENT FOR PRODUCING COPPER ALLOY MATERIAL - A process for producing a copper alloy material from a copper alloy of a precipitation reinforced type, which contains a process to perform individually a dissolution of a pure copper and a dissolution of an additional element or a mother alloy containing the same, comprises the steps of: melting an element and/or a mother alloy at a same time, that is selected from a Ni, a Co, an Si, a Ni—Cu mother alloy, a Co—Cu mother alloy, an Si—Cu mother alloy, a Ni—Si—Cu mother alloy, and a Co—Si—Cu mother alloy with combining therebetween, and melting thereof with an assistance of a generation of a heat of mixing, in a case of forming a high density melt containing at least either one of the Ni or the Co, and the Si, as high density thereof; forming the high density melt as a content of the Ni to be 80 mass % at maximum; and forming an alloy molten metal having a predetermined component and concentration, by adding the melt into a pure copper molten metal to be supplied from another melting furnace. | 12-09-2010 |
