If Tang Hua was in the high-level meeting of the Ministry of Textile Industry, he would definitely jump up and clarify, "Don't draw big cakes, I just supported you in setting up the Textile Machinery Research Institute. How far you can progress depends on the strength of the research institute."
Long before the Ministry of Textile Industry held a meeting to discuss the matter of importing long-staple raw cotton from Egypt, the State Planning Commission had a meeting.
1957 was the last year of the First Five-Year Plan. The speed of industrial expansion and urban expansion was also the fastest, and the total wages of the whole country would also set a historical record.At this time, the ability of agriculture and light industry to provide sufficient products has become a crucial issue.
"From the perspective of the total output value of light industry, we really should eat up the 3000 million raw cotton," Tang Hua said. "Ethylene, ethylene glycol, polyester, chemical fiber fabrics, and garments are a large system. The Chemical Industry Bureau and the Ministry of Textile Industry It is already being done, but it will take time. It would be great to have a small batch on the market in 1958 and a full supply in 1959. Now this unfinished chemical fiber system...increased the value of agricultural output."
Well, the ethylene production line secretly purchased from the West has been put into operation, and the two lines have a total annual output of 10 tons.However, the polyester production line has not been completed yet...
The result is that the produced ethylene is directly pressed to the polyethylene plastic film.This winter, plastic greenhouses are everywhere in Hebei and Shandong, and citizens in Beijing, Tianjin, and many northern cities eat a wide variety of green leafy vegetables in winter.
Having said that, it's not bad.
"We are still far from giving [-] million people a new set of clothes a year. Where there is cotton, there will be cloth and clothes,...and if there is cloth in hand, money will be returned." The chief accountant obviously had money in mind, "This is of course a good thing for the domestic economy. However, we have to guarantee the supply of foreign exchange to buy cotton every year."
Tang Hua: "Isn't the Canton Fair scheduled for April?"
Chief Accountant: "My idea of preparing for the Canton Fair is to recruit some European industrial companies to come in and secretly talk to them about the introduction of industrial equipment. Our domestic exports, in fact, have export potential goods, which have been shipped out through Hong Kong to some extent before. Yes, the Canton Fair this time will at most increase the order quantity a little bit, but the quantity of industrial equipment we import from Western countries will increase substantially.”
Tang Hua: "There are still new things. No, they are not high-tech products, but they have some technological content. We will see when the time comes. As long as the UK insists on doing trade with us, I will have a way to make money from them."

Petroleum is the blood of industry. For an industrialized country, oil & natural gas is an indispensable blood for the operation of the country.
Natural gas reduces the cost of synthetic ammonia-urea production line. Although the ex-factory price of urea has dropped by only 10%, the state's subsidy per ton of urea has dropped by 20%.
The Shengli Oilfield has confirmed to the State Planning Commission that China will not need to import a large amount of oil in three years, but only need to import a small amount of special lubricants.
In addition, due to the discovery of the Shengli Oilfield, domestic locomotive manufacturers began to manufacture diesel locomotives—currently, some equipment was imported from the Soviet Union, but localization work is already underway.
Shanghai Steam Turbine Works is also intensively doing technical transformation.
In 1953, the Shanghai Steam Turbine Factory manufactured the first marine main engine—a three-expansion engine with a small power of 2200 horsepower. This is not a big problem. In 1955, Shanghai Steam Turbine Works produced the first 6000-kilowatt steam turbine.
However, the 6000-kilowatt steam turbine is the same as the 2200-horsepower three-expansion machine, which burns coal...
In the era when the hat of the oil-poor country had not been taken off, no matter whether it was a locomotive or a marine steam engine, if coal could be used, it would be used, and oil had to be imported.
That is, in 1955, the marine coal-fired steam turbines of the Shanghai Steam Turbine Works ceased production, and the oil-burning steam turbines were transformed.
In fact, the amount of modification is not large, and 50% of it does not need to be modified—whatever the steam turbine part is, that is, the boiler needs to be modified, from an oil-fired boiler to a heavy oil boiler.Coal shovelers are gone, replaced by heavy oil nozzles, and the form of water tube boilers has to be redesigned.
In October 1956, the first 10-kilowatt oil-fired boiler and steam turbine rolled off the production line for onshore trial operation testing.
But the action of Shanghai Steam Turbine Works is not the fastest.
In December 1956, a new ship started construction at the 12-meter dock of Jiangnan Shipyard.
All the comrades of the Shanghai Ship Design Institute of the Shipbuilding Industry Bureau were onlookers at the edge of the dock. When the first keel member was placed firmly on the bottom of the dock, all members of the design institute burst into warm applause.
Makino Shigeru: "Thank you, thank you guys from the Design Institute."
Cheng Wang: "Mr. Makino Shigeru, your three years of hard work are gradually turning into results, congratulations."
Shigeru Makino was the happiest person today, walking around the dock, shaking hands and hugging the engineers of the design institute around him.
In a blink of an eye, Shigeru Makino has been in China for more than three years. As a ship design teacher in China, he led these young people to design improved versions of frigates and destroyers, and at the same time, he never forgot to design new ships.
Makino Shigeru's main work is the large "perfect destroyer" that has lasted for two years since the linear design. The [-]-ton freighter started today is a temporary task that started only half a year ago.
Shigeru Makino also participated in the design of civilian ships when he was working in Japan, but he encountered the most magical thing in China: he led the young designers of the design institute to complete the drawing of the entire construction drawings in only 3 months.
Although this is not a warship, it is a civilian ship, but it is a cargo ship with a total length of 169 meters, a deadweight of 1.35 tons, and a full load displacement of 1.95 tons!
It is also the first [-]-ton ship designed and built in China.
In Japan, when designing a 30-ton cargo ship in the late 5000s, if it was not plagiarized or borrowed from semi-finished design drawings, the entire design and drawing cycle would be as long as 12 months.It took only three months to complete the design of this 1.35-ton freighter.
Needless to say, the secret is that the computer in the design institute is the biggest secret weapon, and the "design software" called "CAD" makes Makino often feel that he has not come to China, but to a magical world.
In terms of computer design, Shigeru Makino was on the same starting line as the young designers of the design institute, and at the same time began to learn how to use computers and learn how to use the internal network to collaborate.Fortunately, Shigeru Makino is not so stubborn that he loses his ability to learn. He can master computers as fast as young people.

"Minister Liu sent a telegram from Beijing," Cheng Wang said, "Congratulations on the smooth start of the 1957-ton ship, which is a major milestone in China's shipbuilding industry. Minister Liu hopes that it will be completed and undocked in [-], as long as it does not sink after it is undocked. Victory, after all, we are building a big ship for the first time."
Shigeru Makino: "Minister Liu Nai really underestimated us. Although it took only three months to complete the design, we used the computer to do the most complete structural force analysis, buoyancy calculation and center of gravity calculation. After the tank model test, I am sure that the speed of the sea trial after completion is less than 0.3 knots from our estimated figure. Does Minister Tang Hua have any instructions?"
Cheng Wang: "Minister Tang also called to congratulate him. He also said that as long as the boat can float after launching, it is a victory."
Makino Shigeru: ...
That's how New Year's Day 1957 came.
When Tang Hua looked at the drawings sent by the Ship Design Institute in Beijing, he was also deeply moved.
In the original history, China's first 1959-ton ship built according to Soviet drawings was the "Yuejin" ship, and the first self-designed 1968-ton ship was the "Dongfeng" ship. The latter started construction in 9 and was launched in [-]. It took [-] years to pass the acceptance test.
Is the [-]-ton wheel so difficult to build?It's not difficult to make, as long as the process is correct, it shouldn't be so embarrassing at all.
Now the tonnage of this 5-ton ship is almost the same as that of the "Dongfeng" ship, and it took five and a half months from the start of the project to the start of construction.Among them, it took 3 months from the official start of engineering design to the drawing of drawings.Of course, the hardware guarantee for the construction of this 1955-ton ship is in place. The Heavy Machinery Bureau of the Ministry of Heavy Industry designed and built a large-scale gantry crane in [-], and it was assembled at Jiangnan Shipyard last year.
According to the plan of Jiangnan Shipyard, the construction will be officially started on December 12, and it will be launched on March 28. The berth cycle is 3 days.
很快吗？不快。……“东风”轮船台周期49天，1959年2月25日开工，4月15日下水。不过唐华宁可这艘万吨轮的船台周期长一点，免得在试航和验收流程翻车太多。
On the sketch map of the [-]-ton ship, Tang Hua enthusiastically drew large space-to-ground communication antennas and space tracking radars one after another with a pencil... But he stopped again when he saw the layout of the ship with one shaft and one oar.
"If the first ship of the 1956-type freighter is successfully completed, this type of ship can be put into continuous construction. However, the Shanghai Design Institute can design a series of civilian ships or dual-use ships in parallel to meet China's growing maritime and military shipping needs in the future: "
Tang Hua drafted a proposal telegram sent to Shanghai Ship Design Institute.
"23. Use the same main engine and propeller, but change it to twin shafts and double propellers. The maximum speed should reach 24~[-] knots, so as to meet the needs of fast transportation of special cargo;"
"2.5. It is still a ship with two shafts and two propellers, but with a full-load displacement of about 20 tons and a speed of about [-] knots, it is used as a larger ocean-going cargo ship or a military shipping platform;"
"Three, the improved design of the 1956-type freighter from a single steam turbine to a single medium-low speed diesel engine."
"Early demonstration, line shape and mechanical design of four, 4-ton, 6-ton, 8-ton and 10-ton freighters."

In January 1957, there was another memorable event in Shanghai Jiangnan Shipyard: the first Type 1 destroyer assembled and built using Soviet parts, under the tireless teaching of Soviet experts, and the hard work of the new workers in the shipyard With great efforts, finally, without dragging for too long, I slid down the berth on January 56th.Although it was three months later than the scheduled launching date, the measurement of the center of gravity and buoyancy was quite accurate after launching, and the welding quality of the ship plate was also excellent.
After a simple inspection, the destroyer was towed to the outfitting dock to install the remaining part of the shipboard equipment.
Now that the berth for building the destroyer has been vacated, the Type 56 destroyer "small modification" model designed by the Shanghai Ship Design Institute can be put on the berth.
