Description
The turbine rotor blades are key components of the turbine rotor, directly installed on the main shaft of the rotor and fixed by the impeller. Their core function is to convert the thermal and kinetic energy of high-temperature and high-pressure steam into mechanical energy to drive the rotor to rotate.
The blades are usually composed of three parts: blade profile, blade root and blade tip. The blade root types include T-shaped, fork-shaped and fir-tree-shaped, etc., to meet the requirements of different stress distributions.
During the operation of the turbine, the rotor blades are subjected to extreme loads, including high temperatures (up to 600℃), high pressure, centrifugal force, steam impact force, vibration force, as well as water droplet erosion and corrosion in the wet steam zone. These factors require the blade materials to have high strength, creep resistance, corrosion resistance and good vibration resistance, and high-chromium steel or high-temperature alloys are usually used to ensure the stability of the microstructure.
