Forgings: The Core Supporting Force in Multiple Fields

Forgings: The Core Supporting Force in Multiple Fields

In the modern industrial system, forgings are like sturdy foundations, with their outstanding properties such as high strength and high toughness, supporting the development of numerous key fields. From the aircraft soaring through the sky to the submarines exploring the deep sea, from power stations generating electricity stably to cars roaming around, forgings are applied everywhere and have become the core force driving the progress of various industries.

In the aerospace field, forgings are crucial for ensuring the safety and performance of aircraft. The landing gear of an aircraft needs to withstand significant impact forces and gravity during takeoff and landing. Using high-strength alloy forgings not only meets the high-strength requirements but also reduces its own weight and improves fuel efficiency. For example, titanium alloy forgings, due to their low density, high strength, and corrosion resistance, are often used to manufacture components such as fan discs and compressor discs of aircraft engines, ensuring the stable operation of the engines in harsh environments of high temperature and high rotational speed. In the aerospace field, key components of rocket engines, such as turbine pump rotors and nozzle throat liners, are also mostly made of high-performance forgings. The quality of these forgings directly affects the success or failure of rocket launches.

The energy industry is an important arena for the application of forgings. In the nuclear power sector, large forgings such as pressure vessels and steam generator tube plates of nuclear reactors must have high safety and reliability to withstand high temperatures, high pressures, and strong radiation. The 700-ton nuclear power rotor forgings produced by China First Heavy Industries provided a solid guarantee for the stable operation of nuclear power plants. In the thermal power sector, forgings such as rotor and blades of steam turbines determine the power generation efficiency and service life of the units. The breakthrough in the 620°C ultra-supercritical steam turbine FB2 rotor forging technology significantly improved the performance of thermal power equipment. Moreover, gearboxes and main shaft forgings in wind power equipment can effectively transfer and distribute torque, ensuring the stable operation of wind power generators.

The transportation sector also cannot do without the support of forgings. For instance, the crankshafts and connecting rods of automotive engines are forged components that bear significant alternating stresses during high-speed engine operation. The application of high-quality forgings ensures the power output and reliability of the engines. The forgings for the axles and steering knuckles of heavy trucks ensure the safe driving of vehicles under heavy loads and in complex road conditions. In the field of rail transportation, forgings such as the railway wheel and axle for high-speed trains require high strength, high wear resistance, and good fatigue resistance to meet the requirements of high-speed train operation.

In the field of national defense and military industry, forgings are indispensable. For example, the track plates of tanks and the barrel of artillery are forgings that directly affect the combat performance of weapons and equipment. The barrel is made of special alloy steel forgings and undergoes special processing. After that, it can withstand the high temperature, high pressure and strong impact during the firing of artillery shells, ensuring shooting accuracy and range. The forgings for the propellers and transmission shafts of ships are also crucial for the propulsion system of ships. Their performance directly affects the speed and maneuverability of the ships.

With the continuous advancement of technology, the demand for forged parts in emerging industries is also increasing day by day. In the field of new energy vehicles, the application of integrated die-casting forged parts simplifies the production process of automotive components and improves production efficiency. In deep-sea exploration equipment, the use of super austenitic stainless steel forged parts enables the equipment to adapt to the harsh environment of deep-sea high pressure and strong corrosion. Forged parts, with their outstanding performance, play an irreplaceable role in multiple fields and will continue to provide strong support for the development of various industries in the future, promoting industrial technology to continuously reach new heights.
