There are three trucks in the first row, three flat-headed buses in the second row, and cars in the third row—at this time, there are not enough 30 cars of the same model in Wuhan, so the three rows of 30 cars are Miscellaneous and variegated.

The chairman was on Guishan, looking at the scenery of the three towns in Wuhan while asking about the construction of the bridge.After Yang Zaitian briefly reported the scale of the bridge, the chairman asked:

"With Soviet experts here, such a bridge can be built. Without them, can it be built?"

Yang Zaitian: "Yes."

The chairman turned to Railway Minister Ji Daiyuan: "Do you dare to guarantee it?"

"It can be repaired! We have greatly improved our technology. Designers have accumulated experience in bridge design, and engineers and technicians have learned construction skills. Moreover, domestic steel production is increasing, and the types of special steel that can be smelted and processed are getting better and better. If we build another bridge like this, we can use less or even no steel imported from the Soviet Union."

Yang Zaitian took out a picture album "Wuhan Yangtze River Bridge Project" and gave it to the chairman: "There is a letter in this picture album, which is written to you by all the staff of the Bridge Engineering Bureau of the Ministry of Railways. Moreover, we would like to ask the chairman to send a letter to all the staff of the Engineering Bureau. The staff wrote a word."

Chairman: "I'll have to think about it."

……

In the first half of 1927, the chairman wrote a poem "Bodhisattva Man·Yellow Crane Tower" in Wuhan:

The vast nine factions flow in China, penetrating north and south in one line.Misty rain is vast, and turtles and snakes lock the river.

Where does Huang He go?There are tourists left.Splash the wine, and your heart will rise like a wave!

The situation was actually very bad.Just a dozen days ago, on April 4, the Kuomintang army handed over the guns of the Shanghai workers' pickets, and the next day was the 11 counter-revolutionary coup.At the end of April, many warlords and local powerful factions began to hunt and kill Communist Party members, and the whole country was filled with white terror.

In order to prepare for the worst, the chairman was in Wuhan and sent Yang Kaihui and three children back to Hunan.The Prime Minister had just escaped from Shanghai at this time and rushed to the Wuhan Peasant Movement Workshop to discuss the next move.But the chairman does not know whether the prime minister will arrive safely along the way.

Therefore, the upper gate of "Bodhisattva Man·Yellow Crane Tower" has the dignity of "heavy line" and "massive sky" and "locking the river".But this heaviness is swept away in the final part of Xia Que.Probably only the chairman can write the sentence "the wine is pouring out, and the tide of the heart is rising" in the poem at this time.

……

After the opening ceremony of the Wuhan Yangtze River Bridge, Tang Hua took a bus from Hankou to Wuchang directly—the bridge is really convenient.

Liu Nai also went to the south of the Yangtze River, Tang Hua went to Wugang, and Liu Nai went to Wuchuan.

"The blast furnace was ignited on October 10, and the first furnace of molten iron came out on the 8th. Now WISCO's No. 9 blast furnace and subsequent production lines have all started to move." Zhou Chuandian, deputy factory director and chief engineer of WISCO, and Tang Hua are in the factory area, looking into the distance The No. 200 blast furnace is [-] meters away.

"From the Qing Dynasty to the Republic of China, Wuhan's steel industry has developed for decades, and today we have left them behind in three years," Tang Hua said. "The No. 5 blast furnace will be opened in May next year, but the No. [-] blast furnace and No. It's exactly the same, you have to distinguish clearly when building and debugging."

Zhou Chuandian: "The No. 1.5 blast furnace is basically the same as the No. [-] blast furnace. The steelmaking open hearth furnace is upgraded to a converter. Steel processing is from billet to [-]-meter rolling line and steel plate. We have provided corresponding technical support for the latter equipment. "

WISCO's No. 75 blast furnace is equipped with a super-large open hearth furnace, and the carbon steel produced is directly shipped in the form of billets, supplying the steel needs of various metal processing factories and machinery factories in Central China.Although the annual output is 75 tons, with a little calculation by the State Planning Commission, the [-] tons will be thrown into the demand for steel billets in Central China.

In addition to Central China, South China—Guangdong and Guangxi are also clamoring for steel.

Tang Hua: "There are so many Soviet experts checking in, and I am completely relieved that there are experts from the General Iron and Steel Research Institute to guide the construction of the converter. What should be paid attention to is the discharge of waste water and slag. Whether these two problems can be solved well depends on you and the local government. The rapport of the relationship."

There are three types of pollutants discharged from iron and steel plants, waste gas, waste residue, and wastewater.

At present, we don't have the energy and financial resources to engage in environmental protection projects. What we can do is to discharge waste residue to places that do not affect urban construction, and discharge waste water to places that do not affect the urban environment.

The way to deal with the exhaust gas now is to raise the chimney a bit higher, and try to avoid the city in the downwind direction of the chimney in the site selection of the factory.

WISCO's waste water discharge channel is 4 meters wide and 2.5 meters deep. The discharge channel makes a U-shaped bend in the factory area, and then the factory area goes to the lower reaches of the Yangtze River in downtown Wuhan, and joins the Yangtze River after 12 kilometers out of the urban area.

There are a total of 7 waste water discharge pipes with a diameter of 1.5 to 2 meters in the factory area, which are injected into the discharge channel.These seven pipes are the sources of various waste water in the ironmaking process: gas washing system waste water, blast furnace cooling water, slag flushing waste water, open hearth furnace cooling waste water... Some waste water doesn't look too dirty, while others seem to be dirty. Black and smells like sulfur.

"Is there any plan to cover the wastewater discharge canal?" Tang Hua asked.

Zhou Chuandian: "It just so happened that Qingshan District mentioned this matter to us last week. After we thought about it, we felt that the waste water did have a strong smell, and we should cover it up. We are already preparing concrete prefabricated slabs."

……

The area where WISCO is located is Qingshan District, Wuhan City.

In 1951 and 1952, Qingshan District was established first and then retreated. In 1955, the People's Government of Hubei Province decided to form Qingshan District with 24 townships and one town under the jurisdiction of Wuchang County, Nanhu District, and Donghu District "according to the construction of WISCO and the needs of the non-staple food production base in the city".

The official document of the government directly wrote "non-staple food production base". It is true that tens of thousands of people from WISCO come here. The food is supplied by the state, and the food must be cultivated.

In fact, the non-staple food production base has been producing vegetables one after another since 1955.

Two months before WISCO started production, Qingshan District took over another business that had nothing to do with non-staple food: honeycomb coal plant.

The establishment of WISCO means that there is a huge coal transportation channel from the coal producing area to WISCO.Wuhan Iron and Steel diverts a part of this coal logistics channel to transport anthracite coal lumps to the honeycomb coal plant in Qingshan District.

Therefore, this briquette factory, which should have been a factory-run enterprise, is now a low-tech light industrial enterprise under the management of Wuhan City.

This is just a subsidiary company that WISCO has unloaded. If there are new demands or new situations in the future, Qingshan District will continue to "receive" various industrial demands.

……

Wu boat.

"Of course the three berths for civilian ships must continue to operate, and the quality of construction must not be reduced. Of course, one of the functions of civilian ships is to accumulate skilled workers for military ships."

When Liu Nai arrived at Wuchuan, it happened that a 600-ton passenger ship was launched from the berth and slipped into the Yangtze River.

This is a Chongqing-Wuhan ferry.At that time, there was no direct railway link between Chongqing and Wuhan. Although the boat ride was slow and the Yangtze River twisted and detoured, passenger ships were still the most cost-effective option for transporting people from Chongqing to Wuhan.

If the estimate is correct, the Yangtze River Passenger Ferry will continue to operate until the Sichuan-Han Railway is completed, and then it will completely become a tourist route.

Sabenqi: "It is true that the quality of civilian ships cannot be sloppy. Another thing to report is that our construction plan for passenger and freighter barges is already full, especially for inland river barges. Those steel and coal factories are ordering in groups. .”

Liu Nai: "Then add a berth. The factories of the Shanghai and Zhenjiang Heavy Machinery Bureaus can produce equipment for inland shipyards, including [-]-ton cranes. You don't need to apply for foreign exchange and seek Soviet experts."

Sa Benqi: "Then, will the submarine production line and military ships also add one in the future?"

"There is no plan at present. After the recycling of Luda, the next step of the shipbuilding industry bureau is to renovate and expand the Soviet Navy submarine overhaul factory in Dalian into a submarine production factory. After it is completed, the focus of work will be transferred back to Wuhan."

……

Tang Hua went to Wuchuan to see the ship design department under Wuchuan.

"Minister Tang."

Tang Hua and Huang Xuhua shook hands, "We haven't seen each other for almost two years in a blink of an eye."

"Hello Minister Tang." Peng Shilu shook hands.

Not bad, Peng Shilu returned to China, and Peng Huang got together.Who else is missing, Zhao Renkai who is transferring to the nuclear industry?

"Five years ago, there was nothing here, and now we have a conventional submarine construction plant with relatively advanced technology," Tang Hua said, "But first, the seven of you have to digest and absorb the technology of the Type 7 submarine. This year we are in the East China Sea Have you read the internal report on the encounter between the Yellow Sea and the US nuclear submarine?"

Peng Shilu and Huang Xuhua nodded.

"The tactical indicators of conventional diesel-electric submarines are indeed very different from those of nuclear submarines. It can be said that they are not weapons of the same level at all. However, conventional submarines are the foundation and front-end technology of nuclear submarines. Now we are familiar with the structural characteristics and technologies of submarines through 633. Indicators, learn how to improve the tactical performance of submarines, and then go one step further.”

"The 'Nautilus' is a very large submarine. If we want to switch from conventional submarines to nuclear power, should we refer to the large Soviet submarines?" Peng Shilu asked.
