Abstract

The invention relates to the technical field of copper foil rolling, in particular to a rolling method of a 6 mu m high-strength rolled copper foil, which relates to the field of rolled copper foil processing and is characterized by comprising the following steps: 1) preparing a rolling base material: firstly, smelting and casting copper into ingots, and then carrying out hot rolling cogging, rough rolling, pre-finish rolling and annealing to obtain an alloy rolling base metal with the thickness of 0.08mm, wherein the grain size is less than or equal to 20 mu m; 2) copper foil rolling: the viscosity of the rolling oil is 5.1-6.2 mm/s2The rolling is carried out in 6 rolling passes in total, and the final rolling is carried out to obtain the steel with the thickness of 6 mu m and the tensile strength of more than or equal to 500N/mm2The high-strength rolled copper foil of (1). The rolling of the rolled copper foil with the thickness of 6 mu m can be realized by the method, the thickness tolerance is less than or equal to 0.3 mu m, the tensile strength is 500-600 MPa, the elongation is more than or equal to 1.0%, and the surface roughness Ra is 0.05-0.12 mu m.
