Beschreibung
Zusammenfassung:	The embodiment of the invention discloses a rolled copper foil manufacturing method and rolled copper foil, and the rolled copper foil manufacturing method comprises the following steps: smelting cathode electrolytic copper into a copper rod, and then extruding the copper rod into a copper strip blank; the copper strip blank is rolled into a copper strip with the thickness of 0.15 mm; and the copper strip with the thickness of 0.15 mm is rolled into the copper foil with the thickness of 0.01 mm. The technology for producing the copper foil by using the extruded blank achieves the technical index of the copper foil produced by using the oxygen toughened copper blank (the oxygen content is 150-350ppm) in the hot rolling technology, and realizes the replacement of foreign import. 本发明实施例公开了一种压延铜箔制造方法及压延铜箔，其中压延铜箔制造方法，包括：将阴极电解铜熔炼制成铜杆后再挤压成铜带坯；将铜带坯轧制成厚度为0.15mm的铜带；将厚度为0.15mm的铜带轧制成厚度为0.01mm的铜箔。利用挤压坯生产铜箔工艺以此达到热轧工艺有氧韧铜坯（氧含量为150-350ppm）生产的铜箔技术指标，实现了替代国外进口。
