Working roller of copper foil rolling machine

The invention discloses a working roller of a copper foil rolling machine and belongs to the field of preparation of rollers. The working roller is prepared from the following chemical components in percentage by weight: 0.7 to 1.0 percent of C, 0.2 to 1.0 percent of Si, 0.1 to 0.6 percent of Mn, 1.5 to 3.5 percent of Cr, 0.1 to 0.8 percent of Mo, less than or equal to 0.6 percent of Ni, less thanor equal to 0.5 percent of V, less than or equal to 0.02 percent of P and less than or equal to 0.02 percent of S. The working roller disclosed by the invention has the advantages of high hardness and high hardness uniformity; the thickness of a rolled copper foil can reach 10mu m or lower. 本发明公开了种铜箔轧机工作辊，属于轧辊制备领域，工作辊材质包含的化学成分及各成分重量百分含量为C 0.7～1.0％，Si 0.2～1.0％，Mn 0.1～0.6％，Cr 1.5～3.5％，Mo 0.1～0.8％，Ni≤0.6％，V≤0.5％，P≤0.02％，S≤0.02％，本发明制备的工作辊具有硬度高、硬度均匀性高的优点，轧制出的铜箔厚度能达到10μm以下。
