Directional casting technology has a wide range of applications in manufacturing arc segments (also known as turbine blade segments) of turbine accessories. Turbine arc segments are important components in turbines, usually composed of multiple blades, which rotate and interact with the fluid to achieve energy conversion.
Directional casting technology can form a directional grain structure in the arc segment material, improve its high-temperature strength, creep resistance and fatigue life, and is suitable for high-temperature and high-pressure turbine working environments.
The arc segment is usually designed with a complex cooling channel structure to guide the cooling air through the blades, reduce the operating temperature of the blades, reduce thermal stress, and extend the service life.
Directional casting technology can achieve precision casting of complex geometric shapes, ensure that the size and surface quality of the arc segment meet the design requirements, reduce subsequent processing procedures, and improve production efficiency.
Directional casting turbine accessory arc segments are made of high-quality high-temperature alloy materials with excellent wear resistance, corrosion resistance and high-temperature strength, ensuring the reliability and stability of the turbine in harsh working environments.

Aeroengine:
Aeroengine is one of the important application areas of directional casting arc segments. Arc segments are usually used as blades of high-pressure turbines and low-pressure turbines, which are subjected to the impact and rotation of high-temperature and high-pressure gas and require excellent high-temperature strength, corrosion resistance and fatigue life. Directional casting technology can produce high-quality blades to meet the strict requirements of aircraft engines for high performance and reliability.
Gas turbine:
Directional casting arc segments are also widely used in gas turbines, including industrial uses and energy production. Gas turbine turbine blades need to withstand the impact and rotation of high-temperature and high-pressure gas, and require good high-temperature strength, corrosion resistance and fatigue resistance. Directional casting technology can produce high-quality blades and improve the performance and efficiency of gas turbines.
Turbocharger:
Turbocharger is a commonly used power boosting device in internal combustion engines and diesel engines. It drives the compressor through the rotation of turbine blades to increase the engine intake and performance. Directed casting arc segments can be used for the manufacture of turbocharger blades. They have high temperature strength, fatigue resistance and corrosion resistance, which improves the efficiency and reliability of the turbocharger.
