[214] The power to go to the ocean

Xiaoqiang asked carefully: "Uncle Yuan, the diesel engine factory you told me can produce all diesel engines at the level of the 80s, so which type of diesel engine should be produced specifically?

Yuan Kedi flipped through the documents and replied: "You let your customers thoroughly understand the technical documents before starting production.

The technical information given to you includes the models imported from the Soviet Union in the early days of our country, including the 6e390c medium-speed diesel engine for submarines, the 12ve230zc diesel engine for the main engine of anti-submarine frigates, the 6150c diesel engine as the main engine and auxiliary engine for small ships, and the general-purpose 12v180 high-speed diesel engine. General-purpose 42-160 high-speed diesel engines, smaller power 285, 485 and 4105 diesel engines, and 6250 diesel engines for ship power supply.

你在吃透这些5、60年代苏联技术后，再吃透我国6、70年代在引进基础上后期发展的机型资料，这其中有中船重工集团1958年6esd4382型1470千瓦直流扫气增压低速柴油机，后继的6edz43／67型和9edz43／67a型低速船用柴油机，加上匹配的dz340废气涡轮增压器。另外还有大连船舶集团的esd60／106型2205千瓦回流扫气非增压低速柴油机。上船沪东重机厂回流扫气的9esdz58／100型，6esdz78／155型，6esdz76／160型。上柴厂的12v180zc型735千瓦高速柴油机，130,125,165，250系列中小型通用柴油机，6300型中速柴油机……”

After hearing that Xiaoqiang was in a mess, Yuan Kedi finally said:

"You can start to manufacture diesel engines only after you have thoroughly understood the historical and technical information on the development of these diesel engines. The production line sold to you is based on the technology of the Danish b&w company introduced in 1980. It can produce various types of marine four-stroke medium-speed diesel engines. Marine low-speed high-power diesel engine.

The patented technical materials included here include thin-walled large iron castings, such as the casting of airframes, cylinder blocks, supercharger housings, etc., casting of large boron cast iron cylinder liners, man20/27 and other crankshaft tr forging, large cylinder liners and cylinders Patented technologies such as deep hole processing of head cooling water hole, external circle processing of variable ellipse piston, surface hardening of ring groove of piston head, ternary alloy coating of main bearing bush and connecting rod bearing bush, surfacing welding of heat-resistant alloy of exhaust valve, etc.

This production line is based on the technology of the 80s. Of course, it can also produce these models before the 80s. You can choose the appropriate model for production according to your actual needs.

Of course, I guess that you can't solve the problem of materials at present. I suggest that you can come to my country to buy them, which will definitely be cheaper than making them yourself. "

When Xiaoqiang heard Yuan Kedi's words, he felt like his head would explode. He thought that there were so few technicians in 1950, and he must go crazy when faced with this mountain of materials.

Xiaoqiang thought for a while, and felt that the steam engine was quite reliable, and hurriedly said: "It is impossible for a large warship to be powered only by diesel engines. The power output of diesel engines is flat, and it cannot achieve the ability of high-speed response, start-up and acceleration. Uncle Yuan, you have to sell me a marine steam turbine factory.

Yuan Kedi frowned and said, "If I'm not mistaken, your customer can't even manufacture civil steam turbines?"

Xiaoqiang hurriedly said: "My customer has purchased related equipment and production technology from Qingdao Jielun Steam Turbine Company last year. After the completion of this project, my customer should be able to assemble and produce gas turbine units with a power of 200mw or less than 20 kilowatts. "

Yuan Kedi said: "In that case, I will sell you a complete power system of a 1958-kilowatt marine steam turbine developed and produced by the Harbin Steam Turbine Factory of the First Ministry of Machinery in 3675."

Xiaoqiang made some calculations, and said with a dark face: "This power is too small, and the Luda-level steam turbine needs more than 50000 kilowatts!"

Yuan Kedi took a sip of tea slowly and said, "Don't be in a hurry to eat a fat man, learn the low-power ones first. Back then, marine steam turbines in our country were developed step by step in this way."

Xiaoqiang said anxiously: "It takes 5000 sets of 12-horsepower units to achieve the 72000-horsepower effect of the current two units at the Lvda level. Correspondingly, 12 boilers need to be installed! Uncle Yuan, don't play with me." Ah. If you guessed correctly, this thing burns heavy oil?"

Yuan Kedi laughed and said, "It's normal for warships to install ten or eight steam turbines during World War II, and then one-to-one with ten or eight boilers. Even if one turbine in the power system fails, the remaining There are several turbines in operation. Besides, as long as one such 5000-horsepower marine steam turbine is enough for a [-]-ton bulk carrier, isn’t it good for you to buy it back for civilian use? Burning heavy oil is very cheap. Burning diesel saves a lot of money.”

Xiaoqiang's face became darker, and he drew circles on the table with his fingers, and said patiently: "Uncle Yuan, I bought the drawings and details of this set of 5000-horsepower steam turbines, but do you have any better ones? Steam turbine, don’t want this kind of steam turbine that burns heavy oil!”

Seeing that Xiaoqiang agreed to take this set of technologies, Yuan Kedi said happily: "Then I will give you the 1969 unit successfully developed by Harbin Steam Turbine Factory in 401, including the successor 1983-401 full working condition unit developed in 2, 9195 Kilowatts of power! 12500 horsepower! Install six sets, and there will be 72000 horsepower, which occupies a slightly larger space than the current two Luda-level sets. But it burns aviation kerosene, are you not afraid of spending money?"

Xiaoqiang said angrily: "Is this bigger? It's better to be much bigger!"

Yuan Kedi scratched his head and said: "If you install four units, the speed will be reduced by one. The Luda class has a speed of 39 knots. Why do you want to go so fast? Doubling the speed means increasing the horsepower by ten times, do you understand? Understood. Besides, don’t be obsessed with destroyers, the 401-2 unit is very suitable for small frigates.”

Xiaoqiang was driven crazy by Yuan Kedi, and lamented: "Uncle Yuan, can I also take this set? Don't you have any better ones?"

Seeing Xiaoqiang eating it, Yuan Kedi smiled meanly and said: "Yes! The Model 1970 marine gas turbine designed by 703 in 407 and manufactured by Xi'an Hongqi Machinery Factory has 1.618 kilowatts and 22000 horsepower for a single machine. This is not bad. The power is special warship fuel oil, which is a kind of high-grade aviation kerosene, and you can import it from my country in the future, and I will give you a preferential price."

Xiaoqiang replied: "Well, this one is okay, I want it too, is there anything better?"

Yuan Kedi said: "You make do with these first, wait until your customers can produce these models, the leapfrog development is not so simple, you can't do addition, subtraction, multiplication and division, but you just want to calculate calculus problems, there is no such thing in the world Good thing! It’s not that I underestimate Africa, just these few steam turbine models, plus the previous various diesel engine models, it will take at least 50 years for African countries to fully understand the technology and achieve complete localization!

I will set up a steam turbine mechanical control system production plant for you, and a semi-mechanical and semi-electronic control system factory. As for the fully microcomputerized steam turbine control system, you should not rush to build it. Mechanical control is the foundation. If you don’t understand the basics, other Don't even think about it.

Of course, I will also give you a series of high-pressure marine boiler models matched with the main engine.

Xiaoqiang, do you know why I insisted that you eat all the technical data of the whole series of diesel engines and steam turbine units?It is because it is impossible for you to skip a thorough understanding of these basic models, then imitate, and then create!Don't expect to develop high technology by relying on imagination, castles in the air cannot be built!The money of the African people does not come easily, and the Chinese people cherish this friendship very much.

So don't be too naive, I'm doing this for your own good.China's achievements today are not due to just reform and opening up, but because we have come step by step. Countless revolutionary martyrs have achieved industrialization and technological reserves for our country with unremitting research and struggle, and laid the foundation for reform and opening up. . "

Xiaoqiang said solemnly: "Thank you Uncle Yuan for your guidance."

Only then did Yuan Kedi say with satisfaction: "Then I'll calculate the price for you. Li Mubai, you can calculate the price."

A few minutes later, Yuan Kedi gave a preliminary quotation, which was about 25 billion yuan.

Xiaoqiang didn't agree at first, but just nodded and said: "Leave this price for now, I also hope to get the manufacturing process of steel plates for warships." <The production equipment and technical data of carbon hull steel were imported from the Soviet Union in 1953 The technology has reached the advanced level in the 50s and can meet the steel demand for the production of Luda-class destroyers.

In terms of civil ship steel, we can produce four grades of marine steel, 1983a, 83b, 83c, and 83d, in accordance with my country’s civil hull steel standards in 83, and sell you production equipment, production processes, and formulas, so that you can produce five All civilian passenger and cargo ships and military auxiliary ships of about 8-ton class have a total quotation of [-] million. "

Xiaoqiang demanded: "Can you give us better steel for warships?"

Yuan Kedi said: "Then add the 1960 manganese-titanium-vanadium thin steel for ships developed in 14 for you. This is the steel used for the Luda-class destroyers sold to you."

The black line on Xiaoqiang's face made him understand what Yuan Kedi said earlier, "It can meet the steel demand for the production of Luda-class destroyers". It turns out that the type of carbon hull steel is just enough to make Luda-class destroyers. That’s all for the Luda class, the real Luda class uses 1960 manganese titanium vanadium thin steel for ships developed in 14.

Seeing Xiaoqiang's unkind expression, Yuan Kedi hurriedly said, "I'll give you the formula of 09 manganese-niobium steel. This steel was developed in 1975. It's very good for making various small military ships. It's light and strong."

Xiao Qiang said: "You haven't quoted for submarine steel yet, what's the price for submarine steel?"

Yuan Kedi said: "That is the 1959 nickel 12 chromium molybdenum vanadium series submarine steel developed in 3. This steel is used in my country's first generation of conventional power submarines and nuclear power submarines. Equipment plus information counts as 5 million, and Add up all the previous models and charge you 15 billion."

Xiao Qiang said: "If you offer better submarine steel, I will accept this price."

Yuan Kedi said: "That is the 1983-nickel-12-chromium-molybdenum-vanadium-copper steel developed in 3. The internal crystal quality of this copper-containing submarine steel is quite good, and it can also have high toughness at low temperatures."

Seeing Yuan Kedi's straightforwardness, Xiaoqiang knew that the price was a lot of water, so he asked further: "You haven't given me the low magnetic steel for the minesweeper yet, so I'll give it along with you."

Yuan Kedi saw that the business talks were getting bigger and bigger, so he said happily:

"The 1967 manganese 45 aluminum 17 chromium low magnetic steel developed in 3, this austenitic low magnetic steel is close to a non-magnetic material, has high magnetic stability and yield, and is completely sufficient for building minesweepers. In addition, this This kind of austenitic low-magnetic steel is also used in the structure of submarine magnetic compass walls and degaussing docks, and the effect is also very good! In addition, I will give you the 1965 nickel 10 chromium molybdenum vanadium steel developed in 5 for deep submersibles. It can be used to manufacture marine deep-diving equipment and scientific deep-diving detection submarines. How about it? Xiaoqiang, your Uncle Yuan has treated you well? If you want one, I'll give it to you two."
