Hot-working forming method for phi 2700 cathode roller titanium cylinder forge piece

The invention belongs to the technical field of cathode roller titanium cylinder machining, and particularly discloses a phi 2700 cathode roller titanium cylinder forge piece hot working forming method which comprises the steps that raw material smelting and ingot making are conducted, specifically, titanium sponge is subjected to vacuum smelting, and an ingot casting is formed; forging the cast ingot to prepare a blank, namely performing blank preparation by adopting four-heating-number forging to form a blank; ring rolling and forging, wherein two-fire forming is adopted in the forging process; and annealing the cathode roller. Through the special process control design of the technical scheme, the overall performance in the aspect of product quality is greatly improved. The overall grain size of the forged piece reaches 6.5-8 level of GB/T6394, the hardness of the product is about 116-125 HB, and flaw detection meets the AA level requirement of GB/T5193. 本发明属于阴极辊钛筒加工技术领域，具体公开了一种φ2700阴极辊钛筒锻件热加工成型方法，包括原材料熔炼制
