Equiaxed casting is a casting technology that controls the cooling rate and grain growth conditions to form a uniform equiaxed grain structure inside the casting. This grain structure has no obvious orientation, and the grains are equiaxed in all directions, thus ensuring the isotropy of material properties.
Equiaxed casting is an important process for manufacturing turbine products, especially in the production of turbine blades for aircraft engines and gas turbines. This process can produce high-quality blades with excellent mechanical properties and durability.
Aerospace: In the turbine components of aircraft engines, it ensures reliability and high performance in harsh operating environments.
Industrial gas turbines: Provide high-quality turbine accessories for various industrial gas turbines, adapting to high temperature and high pressure conditions.
Shipbuilding: Turbine-related components used in ship power systems to ensure stable operation in marine environments.
Power generation: Used in turbine systems of some gas-fired power generation equipment to ensure power generation efficiency and stability.
Products used in environments below 650℃ have excellent low-temperature properties, and their strength and plasticity will not decrease under low temperature conditions. They have good tensile strength, yield strength, and service life, and can be used to manufacture diffusers, turbine pumps, etc.
Products used in environments above 650℃ have excellent high-temperature properties, and their mechanical properties and corrosion resistance are still excellent under high temperature conditions. They have good tensile strength and lasting strength, and can be used to manufacture turbine blades, guide vanes, etc.
The physical properties of equiaxed crystal casting blades are roughly the same in different directions, providing stable performance for blade operation.
The equiaxed grain structure increases the difficulty of crack propagation paths, thereby helping to enhance the overall strength and fatigue resistance of the material.
This process is more economical than producing columnar crystal or single crystal turbine blades and is suitable for mass production.
Turbine blades made of equiaxed casting are widely used in aircraft engines and gas turbines. These blades have good high temperature strength and corrosion resistance, and are suitable for high temperature and high pressure parts of turbines.
Turbine disks are important components that support turbine blades and transmit power. The equiaxed casting process can produce turbine disks with good mechanical properties and durability, which are suitable for various turbine equipment.
Combustion chamber liners need to work in high temperature and high pressure environments. The equiaxed casting process can produce liners with high temperature oxidation resistance and corrosion resistance.
Widely used in aircraft engines and gas turbines. This design helps to improve the manufacturing accuracy of blades, reduce stress concentration, and facilitate replacement and maintenance.
Guide vanes are used to adjust the airflow direction and improve the working efficiency of turbines. Equiaxed casting can ensure that these blades have uniform grain structure and good mechanical properties.
