| description | The invention discloses a preparation method of a mirror surface oxygen-free copper strip. The preparation method is characterized in that the technological process of the mirror surface oxygen-free copper strip comprises the steps of smelting, casting, continuous extrusion and stretching; the continuous extrusion process comprises the steps that a cast ingot enters an extrusion die after passing through a cavity of a continuous extrusion machine, an extrusion blank is obtained, the cavity comprises an outlet section, the extrusion die is arranged at an outlet of the outlet section, the outlet section is communicated with the extrusion die through a forming piece, and the forming piece is provided with a forming cavity; the forming cavity comprises a middle area and edge areas arranged at the two ends of the middle area in the width direction of the copper strip, and the cross section area ratio of the middle area to the edge areas is 1: (1.5-3).
