Types of rotor construction | The steam turbine

Four different types of rotor construction have been used on large turbine-generator units on the CEGB system: The monobloc or integral rotor, in which the wheels and shaft are formed from a single-piece forging (Fig 1.104 (a)). The built-up or shrink-on disc rotor, consisting of a forged steel shaft onto which separate forged steel discs are shrunk and keyed (Fig 1.104 (b)).Turbine Shaft - Somers Forge - Forging | Open Die ForgingsTurbine rotor shafts are commonly made of steel grades 25Cr1Mo1VA, 30CrNi3Mo1VA, 26CrNi3Mo2VA, 23CrMoNiWV88 and X750.
