Core Tip: During the use of forgings, the process requirements are very strict, and each piece needs to be consistent without any porosity, excess space, inclusions, or other defects. Components produced by this method.

During the use of forgings, the process requirements are very strict, requiring each piece to be consistent, without any porosity, excess space, inclusions, or other defects. The components produced by this method have a high ratio of strength to weight. These components are typically used in aircraft structures. Of course, this does not mean that these forgings are not allowed to be used in other industries. Obviously, forgings are widely used in various industries of industrial production.

1、 Aircraft forgings: Approximately 85% of the components on an aircraft are forgings by weight. The turbine discs, rear axle necks (hollow shafts), blades, wing beams of aircraft engines, rib plates and wheel supports of the fuselage, and inner and outer cylinders of landing gear are all important forgings related to aircraft safety.

2、 Diesel engine forgings: Diesel engines are a type of power machinery commonly used as engines. Taking a large diesel engine as an example, there are more than ten types of forgings used, including cylinder head, main journal, crankshaft end flange output shaft, connecting rod, piston rod, piston head, crosshead pin shaft, crankshaft transmission gear, ring gear, intermediate gear, and dye pump body.

3、 Marine forgings: Marine forgings are divided into three categories: main engine forgings, shaft forgings, and rudder forgings. The main engine forging is the same as the diesel engine forging. Shaft forgings include thrust shafts, intermediate shafts, and stern shafts. Rudder forgings include rudder stock, rudder column, rudder pin, etc.

4、 Weapon forgings: Forgings play an extremely important role in the weapon industry. By weight, 60% of tanks are made up of forgings. The barrel, muzzle brake, and tail of artillery, rifled barrels and triangular bayonets in infantry weapons, rocket and submarine depth charge launchers and mounts, stainless steel valve bodies for high-pressure coolers in nuclear submarines, shells, bullets, etc. are all forged products. Besides steel forgings, weapons are also made from other materials.

5、 Petrochemical forgings: Forgings have a wide range of applications in petrochemical equipment. Manholes and flanges for spherical storage tanks, various tube plates and welded flanges required for heat exchangers, forged cylinder bodies (pressure vessels) for catalytic cracking reactors, cylinder sections used for hydrogenation reactors, and top covers, bottom covers, and heads required for fertilizer equipment are all forged parts.

6、 Mining forgings: Calculated by equipment weight, the proportion of forgings in mining equipment is 12-24%. Mining equipment includes mining equipment, hoisting equipment, crushing equipment, grinding equipment, washing equipment, and sintering equipment.

7、 Nuclear power forgings: Nuclear power is divided into two categories: pressurized water reactors and boiling water reactors. The main large forgings of nuclear power plants can be divided into two categories: pressure shells and reactor internals. The pressure shell includes: cylinder flange, nozzle section, nozzle, upper cylinder, lower cylinder, cylinder transition section, bolts, etc. The internal components of the reactor work under severe conditions such as high temperature, high pressure, strong neutron irradiation, boric acid water corrosion, erosion, and hydraulic vibration, so 18-8 austenitic stainless steel should be selected for production.

8、 Thermal power forgings: There are four key forgings in thermal power equipment, namely the rotor and retaining ring of the steam turbine generator, as well as the impeller and rotor in the steam turbine.

9、Hydroelectric forgings: Important forgings in hydroelectric power station equipment include turbine shaft, turbine generator shaft, mirror plate, thrust head, etc.

On December 2, the US government announced a new round of export restrictions on China, adding more than 140 Chinese enterprises to the list of trade restrictions, involving semiconductor manufacturing equipment, electronic design automation tools and other types of semiconductor products. In this regard, on the evening of December 3, the China Semiconductor Industry Association, the China Association of Automobile Manufacturers, the Internet Association of China, and the China Association of Communications Enterprises successively issued a statement saying that they recommended that relevant industries in China carefully purchase U.S. chips.

China Semiconductor Industry Association: China’s relevant industries will have to be cautious about purchasing U.S. chips

The China Semiconductor Industry Association believes that the U.S. government’s behavior has once again destroyed the global semiconductor industry’s long-standing consensus on fairness, rationality, and non-discrimination, as well as the purpose of WTO fair trade, and violated the spirit of the World Semiconductor Council (WSC) charter, which is followed by global semiconductor companies, and hurt the efforts of global semiconductor practitioners to unite and cooperate.

 

“The US government’s arbitrary revision of trade rules has caused substantial damage to the security and stability of the global semiconductor industry chain.” The China Semiconductor Industry Association said that in today’s global economic integration, the unilateralism of the US government has not only damaged the interests of Chinese and American enterprises, but also greatly increased the cost of the global semiconductor supply chain. As the US export control measures continue to increase, their counter-biting effect is also continuing to expand. The arbitrariness of the United States’ control measures on China has also caused supply chain disruptions and rising operating costs for American companies, affecting the stable supply of chips in the United States.

 

The China Semiconductor Industry Association believes that American chips are no longer safe and reliable, and relevant industries in China will have to carefully purchase American chips. The development of China’s semiconductor industry is rooted in globalization, growth and expansion in globalization. “We will always adhere to open cooperation, actively deepen cooperation with upstream and downstream semiconductor companies in various countries, and promote the prosperity of the global industry,” the China Semiconductor Industry Association said.

 

The China Semiconductor Industry Association said that it strongly urges the US government to respect the consensus of the industry, return to the spirit of the WSC charter, safeguard the common interests of the global semiconductor industry, and shoulder the responsibility and responsibility of a major country.

 

The China Semiconductor Industry Association will maintain the fairness principle and industry consensus formed by WSC, resolutely defend the interests of Chinese semiconductor enterprises and global supply chain partners, and call on enterprises in relevant countries and regions to strive to become reliable semiconductor product suppliers, and also call on the Chinese government to support the stable development of reliable semiconductor product suppliers.

 

China Association of Automobile Manufacturers: American car chips are no longer reliable and safe

The China Association of Automobile Manufacturers issued a statement saying that it resolutely opposes the US government’s generalization of the concept of national security, abuse of export control measures, and malicious blockade and suppression of China. Such acts seriously violate the laws of the market economy and the principle of fair competition, undermine the international economic and trade order, disrupt the stability of the global industrial chain, and ultimately harm the interests of all countries. “In order to ensure the safety and stability of the auto industry chain and supply chain, the association recommends that Chinese auto companies carefully purchase U.S. chips.”

 

The China Association of Automobile Manufacturers said that the US government’s arbitrary modification of the control rules has seriously affected the stable supply of US chips, and the trust and confidence of the Chinese auto industry in the purchase of chips from US companies is being shaken, and US auto chips are no longer reliable and safe. Automobile is a highly global industry, and China’s automobile industry has always been rooted in the development of globalization. China’s automobile industry is in a stage of rapid development, especially the rapid development of new energy vehicles, which has become an important driving force for global green and low-carbon transformation, and also provides a broad market space for the global automobile industry chain.

 

The China Association of Automobile Manufacturers said that it welcomes global chip companies to strengthen cooperation with Chinese auto and chip companies in various aspects, invest in China, jointly research and development, and share development opportunities.

 

Internet Society of China: Seek to expand cooperation with chip companies in other countries and regions

The Internet Society of China issued a statement saying that in order to ensure the safety, stability and sustainable development of China’s Internet industry, it called on domestic enterprises to take the initiative to take countermeasures, prudentially choose to purchase chips from the United States, seek to expand cooperation with chip companies in other countries and regions, and actively use chips manufactured by domestic and foreign enterprises in China.

 

The Internet Society of China believes that the United States has frequently adjusted control rules, continuously upgraded trade barriers, and ignored international trade rules, which has caused substantial damage to the healthy and stable development of China’s Internet industry.

 

The Internet Society of China pointed out that the United States has generalized the concept of national security and abused export control means to block and suppress China, which has shaken the industry’s trust and confidence in American chips.

 

The Internet Society of China said that while the United States ignores the stability and security of the global supply chain, China should still insist on expanding its independent opening up. On the basis of ensuring security, we will continue to firmly establish and maintain cooperative and win-win relations with all parties in the world and promote the prosperity and development of the global economy. In the critical period of the information technology revolution, China should join hands with all sectors of the world to scale the technological peak and jointly build a better digital future.

The Central Economic Work Conference clearly pointed out that we should adhere to the principle of stability and seek progress while maintaining stability, stressed the strengthening of various policy coordination and cooperation, and made a series of deployments such as “accelerating the construction of a modern industrial system”, “focusing on strengthening weak links in the industrial chain” and “vigorously developing the digital economy”.
