"I would also like to ask Mr. Peng Baisong to say hello to President Nale on my behalf. If he visits China, he will definitely visit our group headquarters." Liu Yongzhuo also politely sent an invitation.

After the two of them exchanged greetings, Peng Baisong turned his body and pointed at the two gentlemen behind him and said to Liu Yongzhuo: "Mr. Liu, I am here today to bring two friends to ask you for help. I will introduce you. This is Mr. Mubila, the deputy president of the State Bank of the Laos Republic, and Mr. Ge Wandi, the deputy minister of the Ministry of Industry."

"This time they are here to bid for equipment for the second thermal power plant in northern Laos. Both of them are my good friends, so I suggest that they first consider choosing your Xinghua News Agency franchise company as the equipment supplier."

Mubila and Ge Wandi hurriedly walked up and shook hands with Liu Yongzhuo.

When Liu Yongzhuo heard that he had a business, he naturally did not dare to neglect it. He quickly ordered the preparation of Qiatan Room and asked someone to invite the chief engineer of Changsha Heavy Machinery.

Hanhua Heavy Industry does not produce large thermal power equipment itself. Among the companies participating in the exhibition, only Changsha Heavy Machinery provides this equipment.

After the host and guest took a seat, Liu Yongzhuo introduced each other to each other, and then Mubila began to introduce the details of their bidding.

Let’s not talk about the transaction here for now. In the venue, there are crowds of people and guests are constantly coming and going.

Not only are there many domestic exhibitors, but many are foreign merchants, most of which are Germans, but also a small number of other Eastern European countries, including Poland after the restoration of the country.

Although no manufacturer in Britain, France and the United States is willing to come to this Wuhan Equipment Exhibition, many merchants come here, especially the most American manufacturing capitalists.

No matter what government ban they are in China, it is already a practice to have free business interests higher than the political needs of the country.

Edward Stark, an entrepreneur from the United States of America, is the founder of Stark Industry and one of the major weapons suppliers of the entire US side.

In terms of advanced manufacturing, he is the first American capitalist to abandon meaningless pride and willing to make a visit to China. As the master of a large industrial empire, he is also the leading expert in nuclear energy physics in the United States.

He is about forty years old, of medium figure, and a well-dressed suit with a mustache on his lips, giving people a very gentlemanly feeling

Standing beside him was his business partner Johnny Depp. A bald fat man always had a smile on his face, but he always gave people a very philanthropic feeling.

Walking through several booths, Edward looked at the precision CNC machine tools produced by Huayang Heavy Industry Group, and sighed repeatedly: "John, the West has been technically surpassing the East since the Industrial Revolution, but it is less than a hundred years now, and we have been passed by this ancient empire again."

Johnny Depp also looked at the dazzling array of mechanical products, and even stayed in front of a beautiful model introducing intelligent robots for a long time. I don’t know if he was concerned about the product or the beautiful model responsible for product descriptions.

Hearing Edward's words, he seemed to come back to his senses, "Edward, you have said this kind of thing many times. Since China built the first nuclear power station, you have been nagging and saying similar words. Don't forget, we came to China this time with a mission."

Edward disagreed with this statement, "What do the bureaucrats of the Ministry of Industry know? They refused to introduce Chinese machines and technologies in order to protect domestic industrial production. As a result, Ford Motor Company took the lead in violating this law. The White House dared not say a single one?"

"That's why we came here, okay, don't complain, let's take a look at the power generation equipment here in China first." John kindly reminded him

It turns out that Stark Industry's current development has encountered a bottleneck

After the war, the United States was fighting for world hegemony with China for national defense needs, so military orders still did not decrease at all. Instead, it urged arms manufacturers to step up the research and development and production plans of military equipment.

In this way, the power generation equipment produced by China is now the best product in the world. However, because of this, the Hualian government strictly prohibits the export of related power generation equipment. At least before 1950, it claimed that it would never be sold to other countries.

Of course, Germany is an exception when it comes to exporting some equipment.

The exhibition was held not by the Wuhan Municipal Government, not by any official organization, but by a well-known association organization among the people-South China Automation Association

The association was founded in 1943. Initially, it seemed to further solve the problem of reducing the dependence of machines on operators in industrial production and allowing human production to enter the era of automation

For digital five-axis linkage machine tools and various types of industrial robots that can carry out production activities without human operation, Edward and Johnny are like swimming in a science fiction world

"In the past, the world's largest and most technologically-based industrial exhibition was undoubtedly the Berlin exhibition, but now and in the future, Wuhan in China is the well-deserved world's best." Compared to Edward, a scientist, Johnny's businessman's atmosphere is stronger.

From the breath revealed from the exhibition, he had already felt the decline of the entire Western world. This trend could not even be resisted. As a white man, he also felt deeply worried.

But as a businessman who is passionate about wealth, he was happy about the goods here, and wanted to buy them all and ship them to the United States to sell them at a good price.

"John, isn't the German government planning to move the Berlin exhibition to Frankfurt? No matter what, the Chinese people learned their skills from Germany. No matter how good they are, they can't compare to Germany." This is Tiou, sales director of Stark Industrial Group, a German-American

"So what, whether it is Berlin or Frankfurt, the quality of the product is determined. At this point, we are too different." Stark is also a German-American, and his family moved to the United States as early as 1912

In this era, many people from the United States are from German origins in high-end fields such as business, science and politics. This is not surprising

"Let's talk about these words later. Let's look for information about the large gas turbine first." The gossip between Edward and Teo was interrupted, and Johnny urged everyone to

Then, they came to the booth of the Chen Heavy Industries Qingdao Steam Turbine Factory, a subsidiary of Tianyu Group, and watched a 60-megawatt gas turbine specially used for nuclear power generation.

"Can you provide relevant information on 60 megawatt large power station gas turbines?" When he arrived at the booth, Stark asked politely whether he did not plan to make a statement here.

The person in charge of the booth here is Shao Weigang. He hurriedly stepped forward and said hello in skillful English.

Seeing that it was a few foreigners, the enthusiasm for other sales was reduced a lot. The Hualian government's equipment export ban has not been lifted yet, and the other party asked about equipment that restricted exports. This obviously has no business to do.

But for the sake of the sales staff, Shao Weigang still stood up and provided enthusiastic and thoughtful service.

"Hello, Mr. Stark, this is the information you need." After a brief exchange, Shao Weigang also took out the information used by the company for publicity. This part does not involve any ban content

"Before this, we have learned about the nuclear power plant solution submitted by your company to the Guangdong Provincial Government. What your company provides to the Guangdong Provincial Government is the second-generation gas turbine technology. The initial gas temperature is above 1200 degrees Celsius. The thermal efficiency of using the combined gas and steam cycle method can reach 4% for a single machine maximum power of 320 megawatts. Can you provide similar technologies to our Stark Industry?"

In the production and application of gas turbines, China has been ahead of Western countries for at least 30 years.

Although he didn't give any hope, Edward Stark couldn't help but make the request. After reading the information in his hand, his heart became itchy

No wonder he was so moved. After the four-megawatt gas turbine for power generation was made in Switzerland in 1939, this type of power generation device with an efficiency of up to 18% completely replaced the old antiques.

You should know that the gas turbine generator set can start quickly without external power supply, and the maneuverability is good. In the power grid, it can drive peak loads and serve as an emergency backup, which can better ensure the safe operation of the power grid, so it is widely used.

"I'm really sorry, the export of this equipment requires government approval. Perhaps your company can submit relevant application forms to the foreign trade department of the Huaxia federal government and then come to negotiate with us." Shao Weigang did not refuse directly, but returned the ball to the Hualian government.

Stark and his friends looked disappointed, so they had to leave with the information they had obtained, and they could only find a way to deal with the Hualian government.

Speaking of this type of gas turbine, in mobile power stations such as automobile power stations and train power stations, gas turbines are widely used because of their smallness and are widely used. In addition, China has already had many portable power supplies that use gas turbines, with the smallest power below 10 kilowatts.

Many people know that the steam engine uses fuel to boil water, produce water vapor, and then use water vapor to push the piston to perform work, converting heat energy into mechanical energy.

The principle of a steam turbine is to turn the piston in the steam engine into a group of impellers. The high-temperature and high-pressure steam will pass through the impeller, which will cause the impeller to rotate, and can also generate mechanical energy and drive the generator to generate electricity.

The biggest disadvantage of steam engines and steam turbines is that the process of heating water with fuel will cause certain energy loss, thereby reducing the thermal efficiency of the equipment.

If the process of boiling water is omitted and the impeller is directly driven by high-temperature and high-pressure gas, the thermal efficiency of the entire equipment can be effectively improved, thereby achieving energy-saving, economical, environmental protection and other requirements

This equipment that uses high temperature and high pressure gas to drive the impeller is called a gas turbine

Compared with steam turbines, there are some other advantages of gas turbines. One is that the volume of the entire equipment can be small due to the elimination of steam circulation systems, so that it can be installed on ships, aircraft and some other equipment as the main engine of the equipment.

Another is that the gas turbine starts much faster than the steam turbine and is often used as emergency power because it does not need to wait for the water to boil.

Gas turbines also have their weakness, that is, the temperature of the gas is much higher than the temperature of steam, which puts strict requirements on the material of the impeller.

The temperature of water vapor is related to pressure. Under normal pressure, the temperature of water vapor is only 100 degrees. Even under the so-called "critical" conditions, the water vapor is pressurized to 250 atmospheres, and the temperature is about 600 degrees. Such a temperature is still far lower than the melting point of ordinary metal materials, so it is enough to use ordinary metals to make impellers.

The gas turbine is different. Since water vapor is not used as a conductive medium but directly uses high-temperature gas to perform the work, the gas temperature in the gas turbine often reaches above 600 degrees.

Scientists have found that the higher the gas temperature in a gas turbine, the higher the thermal efficiency of the equipment. Therefore, continuously increasing the gas temperature in a gas turbine becomes the key to improving the performance of the gas turbine.

Since the establishment of the Huaxia Federation, the gas turbine technology has been truly developed in China, and has gone through three stages. It can also be called the third generation of gas turbine technology.

The first generation of gas turbine technology is characterized by the initial gas temperature between 600 and 1000 degrees, and the thermal efficiency of simple circulation is between 10% and 30% 1939 Switzerland has achieved relevant indicators. Then the United Kingdom and Germany have also achieved remarkable achievements in this regard.

The second generation gas turbine technology refers to the gas initial temperature reaches between 1050 and 1370 degrees, and the thermal efficiency of simple circulation is between 32% and 40%.

The birth of computers, especially the extremely powerful computing power, has greatly improved the research progress in the fields of materials science and mechanical structure.

Around 1950, some manufacturers represented by Tianyu Group proposed the third-generation gas turbine technology, with the initial gas temperature reaching between 1400 and 1500 degrees, and the thermal efficiency further increased to more than 40%.

Many technical difficulties in increasing the gas temperature of gas turbines are the most important ones. The choice of blade materials

The melting point of ordinary steel is about 1500 degrees. If ordinary steel is used to make impellers of gas turbines, then in the gas at 1450 degrees, these impellers will be as soft as cooked noodles and will not work properly at all.

Whether a gas turbine with high gas temperature can be made depends largely on whether it can produce high temperature-resistant materials.

The preparation of high-temperature materials requires another lengthy text to introduce the fact that it involves powder metallurgy technology, high-pressure forging technology and other modern industries, and any technological breakthrough requires the entire industrial system as a support.

China's industry has spent 30 years laying the foundation and accumulated all aspects of technology and equipment with great difficulty. Now it is finally confident to stand on the top of the world's countries.

Chen's Heavy Industry has been engaged in gas turbines for eight years, and the leader is from an aircraft engine.

The purpose of Tianyu Group's initial project was to provide marine hosts for naval ships. For this reason, Chen Ze also specially introduced the famous gas turbine expert Bres from Germany to provide technical guidance.

The Chen family has invested huge amounts of money in the gas turbine project, and the results achieved are also very gratifying.

Six years ago, Chen Ze took out a 300,000-kilowatt gas turbine for ships and was accepted by the Navy. It was used on domestic destroyers two years ago. The 600,000-kilowatt gas turbine for ships was also successfully tested and is currently preparing to be used in the 50,000-ton conventional power aircraft carrier they are building in the South China Sea Fleet.

While developing marine gas turbines, the team led by Chen Ze also developed various gas turbine products for ethylene compressors, central air conditioners and power plants, and their performance indicators have reached the most advanced international level

This time Chen's Heavy Industry came to the Wuhan Equipment Exhibition. Gas turbines were one of the products he planned to focus on selling. Because of this confidence, Shao Weigang, as a salesperson of the company, was not afraid of these high-black and broad-minded foreigners at all.

"Oh, before, others used to buy machines from us, but today they did not expect it would turn around." With infinite regret, Stark left the venue of the Wuhan Equipment Exhibition and sighed at the day's car he bought.

"Don't mention the equipment we urgently need, and after all, the Chinese just don't sell it to us. It's really annoying. Don't they like money? Just for a government ban, they all look very secretive." Tiou complained dissatisfied. As the company's equipment purchasing department manager, this is the most embarrassing day in his life.

"The prestige of the Chinese federal government is still very high. How dare Chinese companies offend the government for a little money?" Johnny is more aware of the situation in China and knows it well.

"Alas, the world's largest 80,000-ton die forging machine is currently in China. This is the technical gap. As for our Stark Industry, we don't even have a 20,000-ton die forging machine. Our powder metallurgy impeller is still transported to Australia for processing. In fact, although we are also moving forward, the Chinese are running too fast."

"This..." Tiou was speechless. This is the truth and it cannot be refuted at all.

Johnny is naturally able to become the second largest shareholder of Stark Industry.

He knew that the mainstream technology for manufacturing high-temperature materials today is powder metallurgy technology, and an important step in the powder metallurgy process is high-pressure die forging. The metal powder must be placed under a die forging machine worth tens of thousands of tons to forging to form

The pressure of the die forging machine directly affects the level of powder metallurgy technology. As Edward said, Stark Industry does not have its own large die forging machine. Many of its powder metallurgy parts need to be transported to Australia to find overseas manufacturers in China to produce OEM, and use the 45,000-ton die forging machine there to forge the pressure.

Many large companies in China have opened branches in Australia, and they are not nominally under the direct jurisdiction of the Chinese federal government. Some laws are relatively relaxed, and technical transactions are more frequent and to be continued.
