Situ Meitang has now discovered that neither Zhou Tian, ​​Zhou Hao, nor Zhao Zhenzhong involved in his conversations, nor the internal affairs of the Zhigong Party. Moreover, after these young people provided a lot of help to Chinese communities such as Anliangtang and Zhigong Hall, the conditions proposed were just to hope that they could recruit some reliable Chinese youths to work. This condition was to benefit Zhao Zhenzhong and others, Chinese workers themselves and even the Zhigong Party. In the long run, it would be more beneficial to Chinese workers and Zhigong Party.

This discovery made Situ Meitang both admire and regret. What was praised was that these young people not only had outstanding abilities, but also had good character; what was regretful was that such outstanding young people could not join the Zhigong Party.

Before Zhao Zhenzhong and the other two left, Zhou Tian reminded: "Brother Situ, it is best to determine the matter about the oil company within this month. At least, in addition to leaving 20% ​​of the oil field development area ourselves, the other scattered development area must be taken. The contact with Rockefeller can have better results. If there is no result, we don't have to rush for a while. In addition, if there are brothers in the hall who invest their income into the stock market, it is best to withdraw all of them before the end of this month. I personally think the current stock market is a bit abnormal."

Mr. Situ is now admired Zhou Tian’s ability to make money. If you don’t say anything else, just for her to turn the more than 40,000 US dollars of brothers in the hall into 11.8 million US dollars in less than 4 years. This is a real real skill! Now, after Zhou Tian reminds, Situ Meitang nodded and said, “I remember it all. However, what price do those scattered moves take?” Zhou Tian smiled and said, “Just don’t just be lower than the market price of the current high-quality oil well development area. There are many rich people in the United States now, and there must be people who can afford the price. Brother might as well publish the news about the high-yield oil well we made in the newspaper, so that we can attract more people. Also, the income this time is from Huamei Investment Company, and there are also the interests of Anliang’s cousins.”

"Haha, you girl, just by your past care for An Liang's cousin, I am willing to do it this time, even in vain."

"That won't be true. This is not the interest of your brother alone, but also the many brothers in the church." Zhou Tian insisted.

"Okay, old man, I won't argue with you anymore, so I will give you my affection on behalf of the brothers from Anliangtang." Situ Meitang was also very straightforward. Anyway, I owe enough love, and it's not too much.

After returning to the manor from Situ Meitang, Zhou Hao returned to Boston to go to school. Although Zhou Tian should have gone back to class, considering the actual situation, she still chose to stay in New York and arrange some related matters. It is just a false story for her return to school now. In addition, the current universities in the United States are not as good as domestic universities in later generations. As long as you can pass the graduation exam, pass the graduation exam, and submit a qualified paper, the professors will not interfere with what you are doing.

Seeing the decreasing number of people in the manor, Zhao Zhenzhong ignored the incidents of the people coming and going in front of him, and devoted himself to the detailed formulation of relevant plans, some manufacturing design and technological innovation.

Zhao Zhenzhong did not pay much attention to the two plans to set up a Ocean Shipping Transportation Company and material acquisition before and after the crisis broke out. He only proposed a list of materials to be purchased and handed over the matter to Zhou Tian. Zhao Zhenzhong believed that Zhou Tian would do better in this regard than himself.

Whether the investment and construction plans in Australia and the Philippines can be realized depends on the acquisition of some companies after the crisis broke out. Now, there is no rush. Zhao Zhenzhong only formulated corresponding outlines for several related plans and turned to other things.

What involves Zhao Zhenzhong's energy is the design of containers and container transport ships, as well as the improvement of steelmaking methods. The design of general containers is very simple, but the design of container transport ships has taken Zhao Zhenzhong a lot of thought.

With the assistance of two overseas students who have studied ship design and manufacturing, Zhao Zhenzhong has consulted many books related to ships in this era and drew rough structural diagrams of container transport ships. As for the detailed production and manufacturing drawings, Zhao Zhenzhong does not have the ability to do it alone. However, even so, it amazed the two Fang Haitao and Ruan Mingbo, who have studied ship design and manufacturing in the United States for four years.

Although only the general structural diagram of the container transport ship was drawn, Zhao Zhenzhong clearly marked the overall technical requirements of this type of ship in terms of load capacity, speed, wind and wave resistance level, and even specifically indicated the requirements for power devices.

Considering the actual situation that the ships must be able to quickly meet the material transportation needs after they are built in the future, Zhao Zhenzhong specially marked that the first three container transport ships with a load capacity of 35,000 tons adopt the steam turbines of this era as the power unit. Starting from the fourth container transport ship, diesel engines that conform to future historical development trends are used as the power unit.

At present, the turbine device and the diesel engine device have their own advantages and disadvantages. The advantages of the turbine are large single-machine power, reliable use, stable operation, no vibration and noise, small maintenance workload, and low quality oil for boilers. However, the oil consumption of the turbine is higher than that of the diesel engine. Even if the turbine device adopts reheat circulation, the fuel consumption is still about 40% higher than that of the low-speed diesel engine, which is poor in economy. Although the diesel engine has high thermal efficiency and good economicality, it meets the historical development trend, the current single-machine power of the diesel engine is less than 20,000 horsepower, and it has not yet met the requirements for burning heavy diesel. Compared with mature gas turbine technology, there is still a certain gap.

However, Zhao Zhenzhong believes that with the emergency response of the first three container transport ships, in a few years, when the fourth ship with a larger load capacity is built later, the diesel engine technology should be able to improve one step further. Then, the diesel engine power will be used.

After designing container and container transport ships, Zhao Zhenzhong and Fang Haitao and Ruan Mingbo said: "This general structural solution and overall performance requirements are considered. However, if you want to turn this structural plan into a detailed production drawing, there is still a lot of work to be done. This requires you two to lead the other overseas students to work hard to supplement and improve it."

"I will keep this structural diagram in the information confidential room of Antai Machinery Company. We must not disclose it to the public before we build our own shipyard and build our own ships. You will also use the time between them to speed up the improvement of your own level. Then you can really take on the heavy responsibility of building your own ships."

After receiving Zhao Zhenzhong's recognition and entrusting, Fang Haitao and Ruan Mingbo were very excited. After nodding in agreement, they worked hard to improve their own level without mentioning it.

After the matter of transporting container ships came to an end, Zhao Zhenzhong devoted his energy to other departments of the machinery company.

Although overseas students have started one after another and the number of employees in the company has decreased a lot, Li Yunshan still arranged overseas students of different grades to go to the company for relevant research when there was no classes during the day. In this way, the entire machinery company seems to be in a state of rest.

After the personnel who went to the artillery factory to study, Li Yunshan organized manpower and used the steel rolling equipment in the company to try to process seamless steel pipes by himself. Since everyone had been studying for nearly a month in the artillery factory, and they were learning about the processing of seamless steel pipes for mortars and the production of mortars, after several experiments and debugging, it was no longer a problem for the production of seamless steel pipes for mortars with thinner pipes. Even for the gun barrels for 75 caliber can be processed smoothly. However, for the 105 caliber and 155 caliber thick-walled long pipes, they can only barely process them, and the effect is not ideal. However, Zhao Zhenzhong was already very satisfied with the current achievement. He encouraged everyone to further study the steel rolling process and strive to master the processing technology of large-diameter thick-walled long pipes as soon as possible.

However, what Zhao Zhenzhong paid most attention to when he went to the machinery company during this period was not the mechanical processing plant and power center, but the metallurgical materials laboratory. In addition to visiting the results of seamless steel pipe processing and production, and also explaining that Li Yunshan should pay attention to the diesel engine power of ships when conducting diesel engine power research, Zhao Zhenzhong focused his energy on the steelmaking experiment of the metallurgical materials laboratory.

Speaking of which, Zhao Zhenzhong is not very good at steel metallurgy technology, but because he often deals with mechanical equipment and weapons and equipment in the past, he also knows a little about the performance of some steel. At least he understands that converter steelmaking is popular in later generations, and he also knows the general situation of steelmaking by blowing oxygen. These are enough to cause a huge innovation in steelmaking technology in this era.

Zhao Zhenzhong had learned about the steelmaking technology of this era from Jiang Feng before, and learned that although there was a converter steelmaking method in the past, due to its own defects, it is basically the world of open furnace steelmaking. In fact, from the 1920s until the world's oxygen top-blown converter steelmaking appeared in the 1950s, in more than 30 years, about 80% of the world's annual steel production was open furnace steel.

After detailed understanding, Zhao Zhenzhong realized that there is no oxygen-blowing converter steelmaking at all. Previously, the method of blowing in the converter steelmaking was nothing but air. However, the method of blowing in air cannot remove sulfur and phosphorus from the steel. In addition, this method has too strict requirements on pig iron composition, and in general, scrap steel cannot be used more. Its economicality is obviously not as good as that of open furnace steelmaking, so it has gradually been abandoned by people.

Zhao Zhenzhong asked Jiang Fengxue: "Blowing in air is to increase the oxygen content entering the furnace and make the various molten materials in the furnace fully react with oxygen. So wouldn't it be better if oxygen was blown directly?"

Jiang Fengxue replied: "In fact, when the German Besmai invented the bottom-blowing air converter steelmaking method more than 70 years ago, he proposed the idea of ​​using oxygen to make steel, but it was not realized due to the limitations of the conditions at that time. Even now, the cost of making large amounts of oxygen is a bit expensive."

"Let's not worry about production costs first, and first consider whether steelmaking using oxygen blown converter can be technically feasible. If it can be technically feasible, then let's consider the issue of oxygen." Zhao Zhenzhong suggested.

With Zhao Zhenzhong's support, Jiang Fengxue and others also built a small experimental converter, and used electrolysis to prepare enough oxygen and store it in some closed airbags for experiments.

After experiments, it was confirmed that the oxygen-blowing converter steelmaking method was completely feasible.

"Jiang Fengxue, in addition to paying attention to the research on steel metallurgy technology, you should also pay attention to the latest situation of refrigeration technology. I heard that liquid oxygen can be produced by pressurized cooling of the air, but it seems that the technology is not mature. If there is any new progress, we must tell Li Yunshan or Zhou Tian in time, so that we can follow up in time." Zhao Zhenzhong reminded, "Of course, in foreign countries, we still need to use the open furnace steelmaking method. As for the oxygen-blowing converter steelmaking method, this is a powerful tool for us to catch up with the great powers in steelmaking in the future. Now we must strictly keep it confidential to the outside world. We will talk about it when we build our own steel production base in China."

"Sir, don't worry, we will never reveal the experimental situation." Jiang Fengxue and others naturally knew the pros and cons, and each solemnly promised.

After staying in the machinery company for nearly 20 days and solving some technical problems that are crucial to the future, Zhao Zhenzhong returned to the manor on October 11.

After meeting Zhou Tian, ​​the two chatted about these things. Zhao Zhenzhong asked: "By the way, do we have any research on refrigeration technology now?"

Zhou Tian also attached great importance to refrigeration technology and replied: "There are no specialists among the first batch of people studying in the United States. In the second batch of people, there are a few people studying. However, they have not completed their studies yet, and many technical problems cannot be solved. It is because the refrigeration technology is not up to standard, and penicillin can only be produced in small quantities under laboratory conditions and cannot be commercially produced."

"Refrigeration technology not only plays an important role in medicine, but also has many other aspects. I have experimented with using oxygen and steelmaking in a mechanical company these days, and the effect is really good. However, to obtain a large amount of cheap industrial oxygen, the refrigeration technology must be passed and obtained through liquefaction. In addition to researching it ourselves in the future, we must also pay attention to the outside world as much as possible." Zhao Zhenzhong suggested.

Zhou Tian nodded and said, "Don't worry, someone is responsible for sorting out this aspect."

"Are you all ready to deal with the crisis now?" Zhao Zhenzhong said with concern.
