The invention discloses a rolling method of titanium alloy plate-shaped forgings. The rolling method comprises the following steps of: substituting forging a titanium alloy billet by adopting three upsetting and three drawing firstly; then carrying out upsetting, punching, frame reaming and rolling on the titanium alloy billet after substituting forging to prepare a high-cylinder and thin-walled ring, wherein the inner diameter of the ring is 85-90 percent of the outer diameter; cutting the high-cylinder and thin-walled ring into two hemi-toroidal parts by using wire cutting; and then straightening by a forging hammer to acquire two plate-shaped forgings. The rolling method effectively avoids the defects about uneven thickness, poor organization homogeneity, multiple forging times and the like of the forgings, improves the quality and the production efficiency of the forging and is used for producing the titanium alloy plate-shaped forgings.
