Abstract:On the basis of the traditional hot working process of Φ2m and Φ1.5m titanium cylinder forging materials for cathode roller such as PCB and CCL electrolytic copper foil, according to the technical requirements of titanium cylinder forging materials which were used for cathode roller of lithium copper foil, the hot process experiments of φ 2.7m titanium cylinder forging material was studied. Based on the field sampling analysis and the effect of the finished product of the cathode roller, the process scheme can meet the requirements of the existing cathode roll products of lithium electro-copper foil for titanium cylinder forgings
