"Tomorrow our second laser team will return to Beijing. In the past four months, everyone has been frozen in Changchun for a season, but they have also done winter things."
After Zhao Zhongyao finished speaking, the students in the second laser group applauded.
"It's time to prepare to write a thesis when I go back," said a student.
Zhao Zhongyao: "The physics department is about to graduate this year, so I am in a hurry to go back.... This year's students are very important."
Because he was in a hurry to go back, Zhao Zhongyao, the construction worker of Changchun Optical Fiber Factory, which was spun off from Changchun Optical Instrument Factory, was no longer on the scene.But looking at the construction blueprint is enough to make Zhao Zhongyao and the members of the second laser team feel excited.
The optical fiber factory is mainly divided into four blocks (branches): optical fiber glass branch, optical rod branch, optical fiber drawing factory, and optical cable factory.
The process used by the fiber optic glass branch is still ultra-high-purity quartz glass, but Zhao Zhongyao believes that ultra-high purity is only a way to reduce loss, and another glass formula can be found to reduce the loss rate even more.This will probably require members of the second laser group to continue research in the next two to three years.
The Optical Rod Branch manufactures glass rods containing optical fiber core and cladding materials.Of course, building an optical fiber factory requires large-scale mass production. The original process of producing optical fibers in the laboratory will be completely changed.
The optical fiber drawing factory is two "tombstones" more than 20 meters high. After the factory is built, it will probably be the most distinctive industrial building in Changguang and Changfiber. In the more than 20-meter-high factory building is an optical fiber drawing tower, with a chuck hanging from the top, where the light rod is stuck, and a heating furnace from top to bottom.Annealing tube, laser measuring instrument for detecting fiber core diameter, cooling tube, primary coating application area, curing lamp.After the coating is applied, the core diameter is detected once, and then the second coating is performed, and the core diameter is detected again.After completing these tasks, the optical fiber comes out from the bottom of the drawing tower, is driven by the guide wheel and the traction wheel to be rolled into a large roll, and sent to the optical cable factory to be coated and made into an optical fiber.
"Mr. Zhao, after I go back, I should be busy with Professor Peng Huanwu's affairs. I will get my second master's degree this year." Zhou Guangzhao said.
Zhao Zhongyao: "That's right. You should go there. What subject did Professor Peng arrange for you?"
"The relativistic helical scattering amplitude and the relativistic particle helical state. I have almost completed the theoretical calculations and experiments last year, and I am waiting for the last step."
Chapter 36, Baiyun Obo and Baotou Steel
Li Huanbo came to Wuhan from Angang in August 1953.
After getting off the train at Hankou Railway Station to go to the construction site of Wuhan Iron and Steel Corporation, the truck was speeding on the road, Li Huanbo's shirt was rattling by the wind, but he didn't feel any coolness on his body, instead, sweat flowed out of his body faster.Crossing the river and coming to the factory site of WISCO in Wuchang, there is no steel factory to be seen, only a construction site, sheds and a big pit.
At that time, Li Huanbo had thought of 9 ways to transfer back to Anshan.His hukou transfer certificate was kept in his luggage for two months and he hadn't taken it out to register his hukou - the WISCO Preparatory Committee is too busy to do such chores.What Li Huanbo thought in his heart was: Check the situation first, stay if you have a problem, and go back to Anshan Iron and Steel if you don't have a problem.
In Anshan Iron and Steel, Li Huanbo is a master of blast furnace welding.Li Huanbo participated in the welding work of the blast furnace built by Anshan Iron and Steel Expansion Project, and his welding skills are well-known in Anshan Iron and Steel.In 1952, Li Huanbo was the only technician in Anshan Iron and Steel who could discuss welding technology with Soviet experts as brothers.
When the master arrived in Wuhan, there was no trace of the blast furnace, but he had to teach a group of kindergarten students.
In August 1953, there was still a big hole in the blast furnace of WISCO, and the construction workers were still trying to dig the hole deeper. In November 8, the pit was dug and the foundation of the blast furnace was poured. A large area was first tied with steel bars, and then concrete was poured in one go to form a huge hardened foundation on which the blast furnace was built.
It took the workers 30 hours to pour the concrete. After the foundation was successfully poured, of course, a blast furnace could not be built on it immediately. The engineering headquarters planned to let the concrete foundation dry until the end of spring of 1954.
During the past few months, Li Huanbo, a welding master, was responsible for giving labor skills lessons to the (intern) welders recruited by the WISCO Preparatory Committee.
Li Huanbo stayed because the workers called him "Master Li" sweetly.Co-teach welders with a Soviet specialist.After three months of examination, 47 of the 14 students passed the examination and obtained the certificate of blast furnace welder.
In the second welding skills class, 33 of the 10 students passed the exam.
When the first batch of students graduated, WISCO's No. [-] blast furnace was tying steel bars into the pit; when the second batch of students graduated, the foundation of Wugang's No. [-] blast furnace had been poured for more than two months.
"Concrete reaches 28% strength 100 days after pouring," Li Huanbo said to his students as he walked back and forth on the foundation of the blast furnace, "It has been two months since it was poured, and I think it has reached 105% strength. The blast furnace. Why hasn’t the construction committee started building the blast furnace yet? What are you waiting for?”
"Master Li, it's coming soon, it's coming soon," said a group leader among the trainees, "The transportation team has been notified and is ready to accept the blast furnace components shipped from Shanghai Water."
Li Huanbo: "Except for the hot summer, everything else in Wuhan is pretty good. If you work hard, you will be the second Anshan in five years. With steel, machinery, manufacturing, machinery industry and light industry will be up. Wait until later In the past few years, when you Wuhan Bank wake up in the morning and open your eyes, no matter where you look, all you see are chimneys and black smoke.”
After listening to the blueprint drawn by Li Huanbo, the trainee technicians looked forward to it.
……
About 150 kilometers north of Baotou, Baiyun Obo.
In the past three years, the Geological Team 241 of the Ministry of Geology came to Baiyun Obo for exploration for the fourth time.
Baiyun Obo is called "Baiyun Bogdu" in Mongolian, which means "rich holy mountain" in Mongolian. In 1927, the China-Swedish Northwest Scientific Expedition discovered a large amount of minerals in Baiyun Obo.Due to the limited technical means and limited time of the delegation, they just thought it was a big iron mine.
The Swedes in the delegation are mainly interested in the dinosaur fossils near the Bayinshandai Temple and the Juyan Hanjian in the Ejina River Basin - these are things that can be packed (stealed) back.The Baiyun Obo Iron Mine cannot be taken away, and Sweden has no shortage of other resources but iron ore.
However, Ding Daoheng, a Chinese member of the inspection team, was very concerned about the Baiyun Obo Iron Mine. After returning, he spent 6 years sorting out the data and re-inspecting on the spot. In 1933, he published the "Report on the Suiyuan Baiyun Obo Iron Mine" in the geological report, proposing "With Baotou as a transportation hub, a railway can be built between Baibao and Baotou, and iron and steel enterprises can be built in Baotou."
Ding Daoheng's proposal report certainly did not have any feedback.
In 1951, the 241 geological team of the Ministry of Geology visited Baiyun Obo again, preparing to explore the iron ore area in detail and find out the reserves, grade and distribution.This careful investigation, yell~~~~~~~~~
This is not an iron mine, but a giant iron-fluorine-rare earth comprehensive deposit!
In addition, there are huge amounts of quartz, phosphate rock, copper mine, gold mine, and potassium-rich slate.
This is why the 241 geological team has come four times in the past three years.
"The reserves of iron ore with a grade above 28% have basically been calculated," said Yan Kunyuan, team leader of Team 241. "One billion tons may still be a conservative figure. Although there is a little less high-grade iron ore, the amount is astonishing."
"The reserves of rare earths, niobium, manganese, and phosphorus may take several years to investigate clearly," said deputy team leader Hai Yishan, "and now there is a difficult problem, a large number of rare earth ores are associated with iron ore."
Yan Kunyuan: "This should not be difficult to solve. Professor Ding Daoheng Ding said that the slag after ironmaking should be dumped in a valley. After the rare earth smelting and separation technology is perfected, we will dig out the slag and refine it again. Finally, Baotou Steel That’s probably the way to go.”
In fact, the exploration of the 241 geological team is still not complete.
According to comprehensive statistics in the 21st century, the iron ore reserves in the Baiyun Obo area are as high as 14 billion tons—of course, there are still no large amounts of high-grade rich iron ore discovered.The most incredible thing is the rare earth reserves. The rare earth reserves in Baiyun Obo are 4300 million tons, and the prospective reserves are about 1.3 million tons, accounting for 2000% of the world's total in 41.However, by 2000, the rare earth reserves of Baiyun Obo will still account for nearly 2020% of the world's total, and the production of heavy rare earth elements in rare earth metals will be almost entirely monopolized by Baiyun Obo.
In addition to this, there are 660 million tons of niobium, an essential material for superalloys.

The development plan of the Iron and Steel Industry Bureau of the Ministry of Heavy Industry: build a new large-scale iron and steel enterprise every two years, and upgrade and transform existing iron and steel enterprises. In 2, the WISCO construction plan was finalized and construction started that year. In 1952, it was Baotou's turn.
Baotou is located in the northwest inland, but when it comes to developing the iron and steel industry, the conditions are not bad.There is no shortage of coal mines in Inner Mongolia. Walking 150 kilometers north from Baotou is Baiyun Obo. From the third exploration in 1953, it can be basically confirmed that Baotou has the coal and iron resources needed to build large-scale iron and steel enterprises. At that time, the Iron and Steel Industry Bureau started Preparations for the construction of Baotou Steel.
Another issue is water resources. Baotou is on the edge of the Yellow River, and there is also a tributary of the Yellow River, the Kundulun River. Currently, the water resources are sufficient.
The main work started in 1953 was the railway from Baotou to Baiyun Obo. The 241 Geological Team came to Baiyun Obo this time and saw the survey team of the Ministry of Railways—to inspect the railway line and station site selection.
But the site selection of Baiyun Obo Railway Station was not decided by the survey team of the Ministry of Railways but by the 241 Geological Team. The 241 geological team draws a map of the iron mines, indicating which mines are the best and easiest to mine, and which mines come next, and then the terminal of the railway line will be located near these mines.
But this is only a small section of the line in Baiyun Obo that is still in the undecided state. The railway line extending northward from Baotou had already begun track laying in January 1954.
Before December 1954, the infrastructure construction of Baotou Steel was about to start officially.
"Captain, does this Baotou now belong to Suiyuan or Inner Mongolia? I heard that Suiyuan will be merged into Inner Mongolia, but I don't know the exact time yet."
Yan Kunyuan: "It probably will be officially merged in June this year. But the steel plant has nothing to do with when Inner Mongolia and Guisui merged. This is a national key project and will not be affected by changes in local administrative regions."
……
Baotou Steel is not the only one of the national key construction projects in Baotou.
In addition to Baotou Steel, there are Sidaoshahe Thermal Power Station, Songjiahao Thermal Power Station, and Tumote Right Banner Coal Mine.
When Tang Hua returns from the Soviet Union, the number of key enterprises in Baotou may increase...
