Turbine blades are key components in gas turbines, used to receive kinetic energy from high-temperature and high-pressure airflow, drive the turbine disc to rotate, and thus drive the mechanical device to work.
The turbine disc is one of the main rotating components in the turbine, responsible for supporting the turbine blades and transmitting kinetic energy, converting gas power into mechanical power.
The stator is a stationary component in the gas turbine, used to fix the guide airflow, so that it interacts with the turbine blades and improves the energy conversion efficiency.
The rotor is a rotating component in the gas turbine, including the turbine disc and the compressor rotor, responsible for receiving and transmitting kinetic energy to drive the mechanical device to work.
The turbine nozzle is one of the key components in the gas turbine, used to guide high-speed airflow, control the flow rate and direction of the airflow, and improve the kinetic energy conversion efficiency.
The guide vane, also known as the guide wing, is located in the turbine and is used to control the flow direction and speed of the airflow, optimize the entry angle of the airflow, and improve the efficiency of the turbine.
A segment is a component in a turbine, commonly found in the compressor part of a gas turbine, used to increase the kinetic energy of the gas flow and reduce pressure.
Springs play various roles in gas turbines, such as maintaining the position of components and providing elastic support.
Bolts and Nuts are used to connect and fix the various components of a gas turbine to ensure tight connection and stability between components.
Free forging is a common metal processing process suitable for manufacturing large and complex-shaped parts. In turbine parts manufacturing, free forging usually involves the following steps:
Select suitable high-temperature alloy materials, such as Titanium alloy, Inconel, Hastelloy, Nimonic, Monel, stainless steel, etc., which have excellent high-temperature strength and corrosion resistance.
The selected metal material is heated to an appropriate forging temperature, usually above the recrystallization temperature of the material, to ensure the plasticity and deformation ability of the material.
Pressure is applied to the heated billet, and it is molded into the desired shape by forging dies or hammering. During the free forging process, the metal undergoes plastic deformation, thereby improving its mechanical properties and material uniformity.
After forging, heat treatment and surface treatment are usually required to adjust the structure, eliminate stress and improve surface quality. Machining, balancing and other process steps may also be required to meet the final engineering requirements and precision standards.
Excellent mechanical properties: Free forging can significantly improve the mechanical properties of metal materials, including strength, toughness and fatigue resistance.
Good material uniformity: Since the metal is deformed under a uniform stress state during free forging, a uniform and defect-free material structure can be obtained.
Cost-effectiveness: Compared with other manufacturing methods (such as casting or welding), free forging is more cost-effective in manufacturing large and high-performance parts.
Free-forged turbine parts are widely used in the following major fields:
Aerospace: Turbine blades and hubs for aircraft engines.
Energy: Turbine blades and hubs for gas turbines and steam turbines.
Industrial applications: Various turbomachinery equipment in the chemical, petroleum and marine industries.
