Although there are still many areas that need improvement and improvement in the production process, and the performance of the products produced cannot be compared with that of the American special steel, Zhao Zhenzhong feels that it has been a great improvement to be able to produce products with the same composition as that of the American special steel. After some consideration, Zhao Zhenzhong asked: "If you give you detailed information on the production process of foreign special steel, can you produce products with the same performance as foreign special steel?"

Jiang Fengxue and the other two thought about it carefully, muttered for a while, and Jiang Fengxue replied: "If you get detailed production process materials for special steel, in the laboratory or in small batches, we can ensure that our products have the same performance as foreign countries. But if you want to build blast furnaces and mass production, the performance of the products may not be completely compared with foreign products for a while. After all, large-scale production also requires high requirements for industrial workers, and there are not many industrial workers in our country who have mastered strong steel smelting technology. Everything needs to be started from scratch."

"If you have detailed production process information and build a new steel metallurgy base in China, at most, how long will it take for you to achieve consistent performance with foreign products?" Zhao Zhenzhong continued to ask.

"It depends on the cultural level of the workers." Jiang Fengxue said after thinking about it. "If industrial workers have a junior high school or above after the blast furnace is completed, we can meet the requirements of our teachers in about one year at most. But if industrial workers are all illiterate, it will take at least three years."

"I understand." Zhao Zhenzhong nodded and said, "Metalogram analysis is a very effective method, you must master it well. In addition, before you get relevant special steel production process materials from foreigners, you must also try your best to explore and research yourself, and strive to create a new production process yourself."

"In this era, the important criterion for measuring a country's strength is to look at its steel output and whether it can produce steel that meets various special needs. In a few years, after you further your studies, our steel industry will depend on you."

Although the three of them were very excited when they heard Zhao Zhenzhong's words, they also felt heavy pressure and responsibility. After looking at each other, Jiang Fengxue said: "Sir, we will definitely work hard! Try to produce our own special steel as soon as possible!"

After saying goodbye to Jiang Fengxue and others, Zhao Zhenzhong and the other two went to the Chemical Materials Laboratory under the leadership of Li Yunshan. On the way, Li Yunshan introduced: "This Chemical Materials Laboratory is under the responsibility of Liu Chenggong, Zhang Xiaoming and Huang Wenli."

"How to set up a chemical materials laboratory in a machinery company?" Zhao Zhenzhong was a little surprised.

"This laboratory was originally used by a machinery company to study various oils, but later it expanded at the request of Liu Chenggong and others." Li Yunshan explained, "Now, in addition to Zhang Xiaoming and some overseas students continuing to study petrochemicals, Liu Chenggong is conducting some acid and alkali chemical research, and Huang Wenli is studying pharmaceutical and chemical industry according to the instructions of his sister."

"Haha, the division of labor among the three of them is quite clear, which is good." Zhao Zhenzhong said with a smile.

"I rejected the guy who originally succeeded, who wanted to do explosives research," Zhou Hao said with a smile, "First, there is a factory here. If something happens to study explosives and Americans will catch it, it will be troublesome; second, you, Lao Zhao, you are proficient in explosives. If you have the time and energy, it is better to make some efforts in basic chemical engineering, and it will be easier to solve the actual needs of the country in the future."

"He didn't object?" Zhao Zhenzhong asked.

"There is no objection, but I'm curious, and I kept asking me where Uncle Zhao learned chemical knowledge about explosives. I had to tell him that you saw it from the book." Zhou Hao explained, and then continued, "I think you will definitely ask you about the relevant questions after meeting you successfully later."

Sure enough, shortly after Zhao Zhenzhong met Liu Chenggong and other three, Liu Chenggong asked Zhao Zhenzhong some questions about explosives, from nitrification, glycerin to Tientier, and then to Hesochin. After answering him in a very brief manner, Zhao Zhenzhong said: "Although these explosives are very important, they are inseparable from basic chemicals. Take Hesochin, the most powerful explosives, for example, as it is made from reaction of ulotropine with nitric acid, which is made from formalin, that is, formaldehyde aqueous solution, and ammonia water. The importance of the basic chemical industry can be seen from this.

.You have to do basic chemicals now, which is very good. However, you can combine basic chemicals and petrochemicals. Chemical raw materials such as formaldehyde and toluene should be obtained in large quantities from petrochemicals through certain methods. These things can be essential raw materials for basic chemicals and military chemicals. In addition, if you and Zhang Xiaoming think about how to build chemical plants and refineries in China in the future, Huang Wenli has to consider how to build pharmaceutical factories in China. Of course, the manufacturing and processing of professional equipment is something that Li Yunshan needs to consider."

Zhao Zhenzhong's words surprised Liu Chenggong and others about his chemistry knowledge. Faced with Liu Chenggong's inquiry, Zhao Zhenzhong had to find an excuse to make excuses.

Through understanding, Zhang Xiaoming's research on petrochemicals has also shown some results. At least now, through the refining of petroleum, it can obtain refined oil materials such as kerosene, gasoline, and diesel, and the oil yield is not bad. Huang Wenli is preparing for future sulfonamide production based on Zhou Tian's suggestion.

After learning about the situation in the chemical materials laboratory, Zhao Zhenzhong said to Li Yunshan on the way back: "In addition to the special equipment required by these experimental departments, you must be responsible for the production and processing, you must also be able to produce other necessary production tools such as spiral micrometers, vernier calipers and some instruments. I suggest you further subdividing the machining factory to form some production teams, which are specifically responsible for the production of corresponding products."

Li Yunshan thought for a while and said, "If this is the case, the current staff will be insufficient by relying on overseas students alone."

"It's a holiday now, and everyone is basically in the company. Will this continue after school starts?" Zhao Zhenzhong reminded him, "The role of overseas students should be to design, manage and guide production, rather than to undertake all the production tasks of the company. If there is not enough manpower, Xiaohao can recruit some reliable personnel from local Chinese through Mr. Situ. After entering the company, these personnel must undergo strict training in production skills and organizational discipline to ensure safe production. I will also give you some production tasks later, which can't be completed by the existing overseas students alone."

"Uncle Master, what task?" Li Yunshan was intrigued.

"There are some engineering machinery that you want to produce." Zhao Zhenzhong explained, "Just just now, I saw that there were bulldozers, excavators and other engineering machinery in your vehicle power research center. I want to draw a few production drawings for bulldozers, excavators and cranes after I go back. You can try to produce some in small batches and transport them to China around the end of next year. I will be useful."

"Of course, these types of construction machinery use diesel engines as power, so you can also refer to it carefully."

"These machines that Uncle Master mentioned are ready-made in the United States. Isn't it more convenient to buy them back?" Li Yunshan was a little surprised.

Zhao Zhenzhong explained: "No matter how good foreigners are, they are from foreigners. Some key things must be mastered in our own hands. Moreover, the types of construction machinery I designed are not comparable to similar mechanical energy in the United States. Besides, through the production of these construction machinery, you can further improve your level and master the powerful diesel engine manufacturing technology. Why don't we do such things in one fell swoop?"

Li Yunshan became excited: "Of course such a good thing needs to be done. However, it seems that I really want Uncle Zhou to go and find Mr. Situ to recruit people."

"Haha, this should be fine, I will cover it. This is a good thing that can increase the income of Anliang's cousins, Mr. Situ will definitely be happy." Zhou Hao agreed with a smile.

After returning to the manor, Zhao Zhenzhong first roughly cleared up the situation he learned about at the machinery company today, and then sorted out the various matters that Li Yunshan and others said today into written words so that Li Yunshan and others could refer to it later.

Later, Zhao Zhenzhong designed more powerful bulldozers, cranes and excavators based on the existing construction machinery of this era.

The crawler bulldozer was developed and successfully developed by American Benjamin Hout in 1904. After more than 20 years of development, by 29 years, bulldozers had basically changed from the original steam engine power to the gasoline engine power. In original history, the Caterpillar bulldozer company in the United States was the world's first bulldozer equipment manufacturer, and successfully launched the first batch of bulldozers using diesel engines in 1931. But now, due to the emergence of Zhao Zhenzhong, the first batch of bulldozers powered by diesel engines will be released more than a year ahead of schedule, and they were produced by Chinese companies.

Considering that there are no hydraulically driven excavators in this era, in order to avoid the hydraulic transmission technology being mastered by the great powers in advance, Zhao Zhenzhong only replaced the power of the existing excavators with diesel engines and improved them in terms of ignition methods. Similar to excavators, there are cranes.

In addition, in order to control production costs, Zhao Zhenzhong used a unified tracked chassis and diesel engine design for these three types of construction machinery, making it form a series of construction machinery.

In addition, Zhao Zhenzhong designed a load truck powered by an eight-cylinder gasoline engine based on the Chevrolet six-cylinder engine I saw today. The normal load standard of this truck is 5 tons, the ultimate load capacity is 8 tons, and the highway speed can reach 50 kilometers per hour. The four-wheel brake, synchronous transmission, safety glass and other technologies that Li Yunshan has mastered are reflected in this load truck.

When designing this truck, considering that the sales situation will definitely not be prosperous after the outbreak of the economic crisis, Zhao Zhenzhong also gave up on the idea of ​​applying for radial tires now and decided to wait a few years before talking about it.

After working hard for more than half a month, by the end of August, Zhao Zhenzhong finally completed the structural drawings and component processing drawings of these vehicles. Looking at the work results in front of him, Zhao Zhenzhong breathed a sigh of relief and thought that the next time should be the time to be busy for military production.
Chapter completed!
