The forging method and its products of tee forgings belong to the forging industry, including screening qualified blanks for blanking, and removing the head and tail of the blank to form a blank in the blanking process; Coating the surface of the blank with an anti-decarburization coating; Conduct initial forging heating on the blank, and the initial forging heating temperature is between 1100 ℃ and 1150 ℃; Carry out pre-forging for preset times, and the total pre-forging deformation is 30% - 45% of the total forging deformation; Conduct final forging, and the final forging temperature shall not be lower than 960 ℃; Perform horizontal punching and vertical punching; Annealing treatment. The initial forging temperature is between 1100 ℃ and 1150 ℃, which is higher than the austenitic transformation temperature. It is easy to deform and process, and is not easy to break. The temperature is above 960 ℃. It has always maintained good malleability and reduced the generation of cracks. When forging, pre-forging is carried out first to reduce the deformation of the final forging, so as not to break due to excessive deformation. At the same time, it can also reduce the wear of the final forging die chamber, extend its service life, and make the metal easy to fill the final forging die chamber, In this way, the machining size of tee die forgings is more accurate.
