For example, the 10st Regiment of the 15st Division of the Marine Corps, who played the role of the U.S. Army, felt that the beach landing was not well organized during the joint exercise, so the whole regiment did it again on the [-]th; in the sky, bombers and MiG-[-]s conducted penetration and interception During the practice, the fighter pilots from the southeast exchanged technology with the fighter pilots from the northeast; the engineers also performed a quick night bridge erection on the Biliu River of the Zhuanghe River.
In the past few days, in the Yellow Sea to the east of Dalian, the individual exercises are the most exciting.
Of the Type 07 destroyers imported from the Soviet Union, except for the 103rd ship that was undergoing maintenance, the other 3 ships participated in the exercise for the first 5 days, and they are conducting joint exercises with the 105th ship "Suzhou" in the past few days.As the first Keeling-class destroyer that has been refitted to form combat effectiveness, the sea confrontation between the "Suzhou" and the "Anshan" is very interesting.
Although one is a Soviet destroyer and the other is an American destroyer; one was built on the eve of World War II and the other was built at the end of World War II, but-they are equipped with almost the same anti-aircraft missiles, anti-ship missiles and radars.
If there is a difference, it is that although the "Anshan" is equipped with the Hongqi-4 missile system, it can only launch the basic type with a range of 13 kilometers, while the "Suzhou" can launch the extended-range type with a range of 25 kilometers-Kilin The hull of the class is large, and the size of the missile magazine is also large enough.

"This large military exercise on the Liaodong Peninsula was very successful and achieved the expected goals. It has summed up a lot of valuable practical experience and improved the coordinated combat capabilities of our military's various arms. It is a successful military exercise similar to actual combat."
In the summary meeting after the exercise, Ye Shuai made a general evaluation of the exercise.
Mr. Peng's speech mainly focused on what to do in the future.
"It is still necessary to continue to strengthen our army's military training under the conditions of future wars. The majority of commanders and fighters should be vigilant, strengthen their combat readiness, continuously improve their tactical and technical levels and the level of combined training of various arms, and be ready to annihilate the invading enemy at any time."
Although the chairman estimated that there will be at least 10 years of peace, and the number of people in the PLA will be reduced to 240 million (in September 1955, after two years of tossing, the disarmament was completed, and now the total number of people in the army is really only 9 million), but now the army has no intention of letting go of Nanshan. Needless to say, the three-armed joint exercise, several lines of the defense industry are running at full speed.
The previous military industry foundation was too poor, and building a national defense industrial system was a must.Not only must a national defense industrial system be formed, but the speed and technology must be high.
The summary meeting of the military exercise was held in Dalian.
At this moment in Dalian, Rong Yiren is thinking about the production scheduling management of the new quilt factory, and a group of workers and engineers in Dalian Heavy Machinery Factory are studying the blueprint of a huge machine.
"These three beams each have a large plane with a length of 10 meters and a width of 8 meters that needs to be processed, and our country does not have such a large milling machine, what should we do?" said Xu Xiwen, chief engineer.
Shen Hong, director of the Heavy Machinery Bureau of the Ministry of Heavy Industry: "We can't wait for the large milling machines produced in Shenyang to arrive, it will be too late."
Deputy Chief Instructor Lin Zongtang: "Why don't you try eating an elephant with ants?"
The so-called ants eating the elephant is to hang a medium-sized mobile milling machine upside down, install it on the parts, and process while moving. Moreover, several milling machines can be hoisted at a time to speed up the progress.
The drawing in the hands of the three engineers is a 12000-ton free forging hydraulic press.
At present, one steam turbine factory (Harbin) and five diesel engine factories (Changchun, Dalian, Shanghai, Wuhan, Luoyang) have been established in China. In imitating the engine of the T-54 tank, Wuhan produces medium and high-speed marine engines and four types of civil diesel engines.
These six factories have one thing in common, that is, the steam turbine rotors and main engine crankshafts all have to be imported from the Soviet Union.
Although many parts can be made by ourselves, which reduces the amount of foreign exchange used, it is still not reassuring to buy core parts such as the rotor and crankshaft.
The crankshaft of the engine must be forged by a hydraulic press, because the mechanical performance requirements of such parts are too high, so high-strength steel can only be smelted first, and then the steel ingot is hard squeezed into the shape of the engine part.This is the only processing method that works. Others, such as hot rolling, stamping, turning, casting, etc. are all useless. After they are made and put into a diesel engine, there will be a "collapse!"
For the localization of rotors, crankshafts, main shafts of ships and vehicles, support shafts, work rolls, etc., it is necessary to build hydraulic presses.
……
The development of a [-]-ton hydraulic press was actually Shen Hong's first report.
"Let's talk about hydraulic machines again. In 1947, the Kuomintang dismantled four sets of 1000-2500-ton hydraulic machines from Japan, and only one was installed. Up to now, my country still relies on imports for large forgings. I visited the Soviet Ural Heavy Machinery in 1954. After returning from the factory, I often thought about it. I think we can make a [-]-ton hydraulic press. It will take him a year or a year and a half to make a [-]-ton hydraulic press. It can be used if the quality is not good. This is of great help to me forging big pieces myself."
In April 1955, Tang Hua saw the report and immediately approved it.Moreover, Shen Hong's estimated time of one or one and a half years was changed to three years.
"Project: free forging hydraulic press of more than 12000 tons; completion time: before June 1958, 6; other requirements: performance standards, reliable quality, and can be used in industrial production immediately."
This is the index set by Tang Hua for the [-]-ton hydraulic press project of the Heavy Machinery Bureau.
This time, Dalian was chosen to manufacture the first 6000-ton hydraulic press instead of Shanghai because Dalian Shipyard has a 57-ton hydraulic press for reference.The Shanghai Diesel Engine Factory has just ordered a [-]-ton hydraulic press from the Czech Republic, and it will be delivered in early [-].
In addition to the ready-made reference materials in Dalian, the ability of Dalian Jianxin Company to produce special steel and cast steel is also an important reason.The large parts of the [-]-ton hydraulic press need to be made of extra-large forgings and cast steel, and the sizes are particularly huge.
The hydraulic press has a total weight of 2500 tons, the largest single part is 300 tons, 100 parts of 300 tons to 12 tons, and more than 50 parts of about 20 tons. This is not a heavy machine, it is almost a "giant machine".
The main structure of the hydraulic press has four large columns, each of which is 18 meters long, 1 meter thick, and weighs 80 tons. Not only does it require a special processing and manufacturing workshop, but also the connection of the columns must use electroslag welding technology, and the thickness of the welds is generally 80~ 300mm, the thickest 600mm.
There are more than 4 large and small parts in the whole machine, and there are more than 7000 important load-bearing parts during work. Each of these parts must be precision-machined by metal cutting before installation.
……
"Minister Tang Hua is very concerned about the development of the [-]-ton hydraulic press," Shen Hong said, "He instructed that this thing is not so simple to build, rejected my plan of one to one and a half years, and gave us three years Time. Moreover, when I came to Dalian from Shanghai, Minister Tang asked, do you have any difficulties? If you can’t solve it, you can come to me directly.”
Xu Xiwen: "There are many difficulties..."
Shen Hong: "I don't think there are any insurmountable difficulties, you guys try to solve them yourself."
Xu Xiwen: "I understand, Director Shen. We have nowhere to put things that foreigners can make in the 30s and [-]s, and we need to ask Minister Tang for help."
"It's good to understand. By the way, let me tell you something else," Shen Hong said, "If you complete the national key projects and high-tech projects independently, Minister Tang said, such a person, two years Once you were elected as a member of the Academy of Engineering, he will definitely carry you into the Academy of Engineering. But if it is not done independently..."
"I must knock it down and finish it!" Xu Xiwen seemed to be pumped out. After three months of suffering in the workshop, his somewhat tired spirit was now full of fighting spirit.
Chapter 107, Movie Preview
In the last month of 1955, people realized that something was wrong:
This year's Nobel Peace Prize has not been awarded.
In this regard, the statement issued by the Norwegian Nobel Committee is: In 1955, the world was deeply mired in the terror of nuclear weapons, and the situation was still deteriorating. No one made effective efforts for world peace. Therefore, the 1955 Nobel Prize The Peace Prize is vacant.
Look, it's the perspective of colonialism again.
Nehru, who at least organized the Asian-African Conference in 1955, was making efforts for world human rights and world peace. From a hindsight perspective, Nehru, or Nehru + Prime Minister deserves the name of the Peace Prize.However, in the eyes of Europeans, these countries that broke away from colonial empires and gathered for meetings are provoking trouble. How could it be possible to award Nehru.
In the last month of this year, the production line of the T56 computer started, and Huang Jiqing's oil exploration team was formed.
"Old Huang, we set off in December and arrived in the northeast, where the weather is at its coldest. You have to pay attention to your health," Tang Hua said.
Huang Jiqing was wearing a thick down jacket, which seemed to be wrapped in gray cotton balls, and a cold hat with ear protection on his head. He laughed: "It's not that serious. The key area of my exploration is the Liaohe River Basin, which is not much colder than Beijing. .There are also many large and small cities around, and the supply of logistics materials is relatively easy.”
Tang Hua: ...
He kindly lured Huang Jiqing to the Daqing Oilfield, but after looking at the histogram, ignoring the difference in the height of the column clusters, he decided that the Liaohe Plain had a higher chance of producing oil than the Songliao Plain, so he went straight to the Liaohe River.
Since the early 40s, Huang Jiqing has always been optimistic about the Liaohe Plain in his writings and previous academic conferences.Of the several areas he demarcated, in the Northeast, he believes that the Liaohe Plain is the one with the highest probability of oil production, followed by the Songliao Plain.
But Liaohe...there is clearly the Liaohe Oilfield.
In the 21st century, the annual oil production of Liaohe Oilfield has reached tens of millions of tons, but both the total geological reserves and recoverable reserves are only medium-sized and small-scale oil fields, which are incomparable with Daqing, Changqing, and Shengli.
Since Mr. Huang is determined to explore the Liaohe Plain first, let him go.Anyway, oil can be drilled out, right?
Moreover, after careful investigation after the oil is produced, it will definitely be found that the oil reserves of Liaohe Oilfield are not too large, which is far worse than Li Siguang's Shengli Oilfield.Based on the conflict between Lao Huang and Lao Li, Huang Jiqing will definitely not give up, and has to continue to look for oil in the northeast.
Yu Qiuli came to see Huang Jiqing off today, and he was also in high spirits.Lao Huang's academic and theoretical attainments are not good, but his characteristic is (among geologists) that he is relatively nerdy.
It's all right now. First, Li Siguang rushed to the Bohai Sea area and searched for a year to find a Shengli oil field. Then Lao Huang envied him and took a mission to find oil in the Northeast.
