Mastering production of rotor forgings resulted in development of technologies enabling to reach through section working out of metal more than 2 000 mm. All Russian turbine generators with power more than 50 MWt are equipped with solid-forged rotors, manufactured at production facilities of the Corporation enterprises from ingots weighing 180 to 360 tons, and such products have been successfully exported. More than 1 000 rotors of high-pressure and medium-pressure cylinders were manufactured from ingots weighing 30 to 142 tons. Rotor forgings of low-pressure cylinder for turbines with power 1 000 MWt are made of ingots weighing 235 tons.
Maximum parameters of forgings for rotors and disks:
rotor shaft length – up to 16 000 mm
barrel diameter – up to 2 000 mm
disk diameter – up to 2 500 mm
disk height – up to 500 mm
Maximum weight of forging – 260 tons
