Chapter 189: 80,000 tons of die forging press
Everyone was stunned.
80,000 tons of die forging press, this is the world's first! Just to build a girder of a warrior car in front of you, can you use a hydraulic press of this level?
Needless to say, 60,000 tons, even if it is 40,000 tons, there are only three countries in the world that have it!
The advanced die forging press technology was developed during World War II, and Germany built a total of four die forging presses of more than 10,000 tons before 1944, including one of 30,000 tons and three of 15,000 tons.
After the end of World War II, the United States and the Soviet Union quickly dismantled all four, after which, for the development of the Air Force, the Americans began to build larger die forging presses, and in 1955, the Meesta Heavy Machinery Plant built a 45,000-ton die forging press and a 31,500-ton die forging press for Alcoa. The Lauwe Company also built one of the same tonnage for Weiman Gordon, and the Yankee's aviation industry relied on these four die forging presses.
In order to develop his own aerospace industry, Lao Maozi is also developing advanced die forging presses, and Lao Maozi is even more generous, building two of the world's largest 75,000-ton die forging presses, plus three 30,000 tons and one 15,000-ton one, making Lao Maozi the country with the strongest technical strength in the die forging press in the world.
Look at Europe again, Europeans used to only have 30,000 tons of die forging presses, until 1976, the French Auber Duis Special Steel Company, from Lao Maozi's new Kramatto Heavy Machinery Factory purchased a 65,000 tons of die forging hydraulic press, only to achieve the technical upgrade of the die forging press, can produce titanium alloy die forgings and aviation aluminum alloy die forgings.
However, the demand for large die forging presses in Europe is huge, for example, when Airbus develops, because the die forging press at hand is not enough, so that the landing gear blank must be sent to the old Maozi to press, otherwise it cannot be built.
From these technical introductions, it can also be known that the large-tonnage die forging press, which is used in the aviation and aerospace industry, the landing gear of large aircraft, belongs to the thin-walled structure, but the demand for bearing capacity is relatively large, so it must be forged by the die forging press, and the structural parts of large aircraft also need this die forging press.
Now, Yun 10 has been dismounted, the reasons for the dismount are many, in various technical analysis, the domestic inability to produce large aircraft landing gear and structural parts, is an important argument of opponents.
In fact, what ordinary people can think of, how can the R&D personnel of Yunshi not think that after the start of the Yunshi project, the manufacturing plan of 60,000 tons of die forging press has begun in full swing.
After all, in 73 years, Dongfang First Heavy Machinery built the first 30,000-ton die forging press, and in 74 years, it built a 30,000-ton non-ferrous metal die forging press, even if it was in 82 years, the two heavy machines also built a 10,000-ton multi-directional die forging press for Southwest Aluminum Plant.
For Dongfang, a 60,000-ton die forging press is not difficult to build, all that is needed is the reason for construction.
In 75 years, one machine * and three machines * submitted a report to the superior to build a large die forging press, which was approved, and the two heavy machines and Tsinghua University cooperated to start the design work of this 65,000-ton multi-directional die forging press, and in 81 years also carried out the test of a 1,000-ton simulated prototype, however, the Yun 10 project was launched, and the related projects naturally did not need to be built, and the country wanted to develop the economy, and money was needed everywhere, and it would not continue to spend money on such unnecessary projects.
Unless...... There are other investments, and now, Qin Feng, the head of the wealthy Pacific Group, is planning to engage in this project, and moreover, the tonnage will be increased to 80,000 tons! How could this not surprise everyone.
After being surprised, Yang Lao spoke: "As long as you pay for it, our troops will help coordinate, there is no problem, after all, if your 80,000-ton die forging press comes out, it will be the first in the world, and our country will definitely support it." ”
If it is other equipment, then go directly to the relevant factory to order, but the 80,000-ton die forging press is not easy, and the state must help coordinate, and it is completely fine for the troops to come forward.
"However, you really only plan to forge a car girder when you build such a big guy?"
To say that using this kind of big guy to forge the girder, the quality of the build is absolutely just, the car is scrapped, and the girder will not break, but this is also too big to use, right?
"We are built for forging car girders, however, after it is built, it can also have other functions, for example, if the bomber landing gear of the Air Force wants to be manufactured as a whole, you can put the blank on our machine to forge it, if the relevant departments need some large-size seamless steel pipes, you can also switch special molds, turn this die forging press into a vertical extruder, and directly extrude out large-diameter thick-walled seamless steel pipes."
Ordinary steel pipes are pressed out of steel plate coils, and the interface is easy to collapse if the quality is poor, and the steel mills in Liangxiang Township are pounding out of this kind of goods, if the internal pressure is high, it will also collapse, so some special places must use seamless steel pipes, such as high-pressure steam in the boiler of power plants.
How to make seamless steel pipes? Drill a hole with a deep hole, and then expand the chamber, it becomes a steel pipe, which is the same as the manufacturing process of the gun barrel, and in foreign countries has begun to use vertical extrusion technology, with a powerful hydraulic press to press the red billet, just like pressing plasticine, the billet will be turned into a steel pipe.
However, there is no one in China, and it is too expensive to make it with the process of making cannon tubes, and the prices per ton of P91 and P92 seamless steel pipes purchased from the United States are 120,000 yuan and 160,000 yuan respectively!
Therefore, the country needs advanced production technology of large-diameter thick-walled seamless steel pipes, which call for large-tonnage hydraulic presses.
"In other words, if we want to make a cannon barrel in the future, just put it on your machine and press it, and a cannon barrel will come out?" Li Runzhu thought of something, and immediately asked excitedly.
"Sorry, we only produce civilian products." Qin Feng said: "We are responsible for processing large-diameter thick-walled seamless steel pipes, and it has nothing to do with us as for what we use them for. ”
The big guys all smiled excitedly.
"Okay, as long as you pay for it, the troops will help you coordinate!" Yang Lao repeated what he had just said: "What else do you need?" ”
"Die forging presses need steel, and we want to introduce foreign production equipment to build a modern steel mill."
80,000 tons of die forging press, only 20,000 tons of self-weight, the parts of this die forging press are made on site, so, to build a die forging press, you need to build a steel mill first!
The domestic steelmaking technology is not advanced, and the steelmaking equipment needs to be purchased from abroad, even if Qin Feng has foreign exchange in his hand, it is impossible to buy things directly with foreign exchange, because this import is managed in a unified manner, if Qin Feng wants to do it himself, it will definitely be controlled by all aspects, and in the end everything will have to be dragged yellow.
In fact, the project of 80,000 tons of die forging press is not necessary, this steelmaking equipment is the most important, with the development and growth of their Pingwang motorcycle factory, the demand for steel is also increasing, and the small two-town steelmaking plant is not available, if you purchase it......
It's better to take everything into your own hands, after all, in 88 years, the country has an important project, called the price pass, you can't get the planned share, if you buy from the market, the price of steel will be unacceptably high.
"Mr. Qin, we can coordinate the steel matter, we are next to the capital steelmaking plant, do we still need to build another steelmaking plant?"
"Can the army guarantee the steel needs of our Pingwang Motorcycle Factory in the next few decades?"
The people were silent.
Mr. Qin, don't look young, look far away!
"Mr. Qin, if you purchase steelmaking equipment from abroad, it will cost valuable foreign exchange, whether it is Wuhan Iron and Steel or Baosteel, their production equipment is purchased as a national project."
"We don't want to build a large steel company like Wuhan Iron and Steel and Baosteel, we just want to build a medium-sized steel mill." Qin Feng explained: "As for the purchase of equipment, it is completely possible to purchase second-hand equipment eliminated abroad, the price will not be too expensive, we can barter down, but the procedures are not easy to go." ”
In the mid-eighties, the existing domestic steelmaking enterprises in order to enhance their production capacity, began to purchase foreign second-hand equipment, in the Seventh Five-Year Plan to the Eighty-Five period, a total of more than 40 enterprises from abroad to purchase more than 100 sets of second-hand equipment, especially rolling equipment, these equipment is the level of the seventies, has fallen behind in the world, but for the East is still relatively advanced, after all, the Oriental steelmaking has been stagnant under the shackles of the old Maozi technical route, it is time to move forward.
"Okay, we can help with the coordination." Yang Lao nodded again, and suddenly thought of something: "Do you still need a venue?" ”
Qin Feng showed a wry smile: "Forget about the site of the capital, let's find a piece of land from Sugar Mountain, this shouldn't be difficult." ”
If it is possible, of course Qin Feng hopes to set up the factory in the capital, even if it is to be relocated in the future, that land is also our Pacific Group! However, through the Pingwang Motorcycle Factory, Qin Feng also realized how difficult it is for a private enterprise to develop and grow, so he gave up the idea of setting up a steel mill in the capital.
It's better to go to Sugar Mountain to find a place, Shougang relocated, that is, to go to Sugar Mountain, and go to occupy a piece of feng shui treasure land in advance.
"Okay."
After the matter was discussed, the leaders watched by the car for another half an hour before they all went back trembling.
Qin Feng was called to the office and talked freely for a while, and when he came out, the sun had already reached the west.
It's been another busy day!
Qin Feng restarted the car and drove out of the compound, originally planning to go back to Pingwang Motorcycle Factory, but after thinking of something, he turned around at the intersection and headed to the Chocolate Building.
During this time, Qin Feng has been busy with the affairs of the motorcycle factory, day and night, while Zhao Jiao is dealing with the affairs of the Pacific Group.
As a result, the two haven't seen each other much during this time, except for a small get-together at times like the winter solstice, Qin Feng is a man with strong blood, and he has just become a monk not long after he got married.
Today this matter has finally come to an end, just go to your wife, see what she is up to, watch a movie together in the evening, relax, and then ......
With a relaxed and pleasant idea, the warrior off-road vehicle drove on the road of the capital, the north wind was bleak, and there were few pedestrians on the side of the road.
The Chocolate Mansion had already appeared in front of him, and Qin Feng was thinking about having something to eat together for a candlelight dinner in the evening, when suddenly, a woman's exclamation came from the wind in front of him.
"Someone's coming, someone is robbing!"
Robbery? The eighties were not peaceful, even if it was the capital, there were such a group of idle guys, this tradition even existed from before, such as the Qing Dynasty, there were stubborn owners who would tie their braids with wires to make the braids up, and in the chaotic period, the stubborn owners would fight and fight because of the beating of their mothers-in-law, but at that time, there was not much robbery.
Now, the robbers are not necessarily locals, they may also be outsiders, but they are definitely bad people.
Before Qin Feng could finish thinking about it, a motorcycle appeared on the road in front of him, with an orange fuel tank raised high, a huge radiator below, the exhaust pipe still on the left, the chain on the right, and the round headlights, which made people recognize the model of this motorcycle at a glance: the izh planeta sport motorcycle from the Soviet Union!
Although the capital has banned motorcycles, but this is only on the surface, there are always people behind the scenes, what can be seen in the second ring and thirteen langs after many years of banning motorcycles, and people who don't want to die are everywhere, and this kind of person has to choose a suitable motorcycle.
In front of this motorcycle is a Soviet product, the quality is not good, and it is a single-cylinder engine, however, the displacement is as high as 350 ml, the maximum power reached 35 horsepower, in the Soviet market, belongs to the same class of models with the largest horsepower and the fastest speed, deeply liked by the motorcycle party, in the late seventies, this motorcycle also began to go to the Eastern market.
Unexpectedly, it actually appeared in the hands of the robber!
The rider in front of him twisted the throttle handle fiercely, the engine let out a roar, and was driving at full speed, and there was a man sitting in the back, this man was carrying a bright flaky object in his left hand, and a bright red lady's bag in his right hand, and was turning his head back, shouting something.
That's them!
After Qin Feng saw it at a glance, he felt that these two guys were stupid enough, what was the advantage of motorcycles? Walking through the streets and alleys, robbing things, you don't even get into the alley to escape, you still have to take the main road, even if there are no police here, you are too ostentatious, right?
At this time, the rider in front also saw the wide vehicle coming from the opposite side, and his heart suddenly felt weak, this car looked unusual, I don't know who is inside, will he take care of his own business?
At this moment, the car on the opposite side suddenly turned left and came to his side of the lane!
The rider shouted to the back: "Brother Pan, be careful!" ”
After saying that, the rider slammed the throttle to the end, and then lifted the front handlebar hard, this guy actually wanted to play a stunt and fly the motorcycle!
You've watched too many Hong Kong and Taiwan films, right? Qin Feng thought secretly in his heart.
Sure enough, the guy named Pan Ge in the back didn't sit firmly, he fell directly from behind, rolled on the ground a few times, and the fiery red lady's handbag that he had just snatched was lost, but the flaky object was still in his hand, but there was blood on the flaky object! Just when he rolled, this thing left a bloody hole on himself!
This Pan Ge was dumbfounded at the moment, and shouted loudly: "Old Pao'er, wait for me!" ”
At this shout, the motorcyclist in front turned his head to take a look, and found that the person in the back seat had fallen, and suddenly he was in a hurry, and the motorcycle did not fly, and it fell to the ground with a bang, and the shock absorber was on the spot, and the tires and fenders rubbed against each other, making a screeching sound.
Boom!
At this moment, the old cannon in front heard a crash, and then, in surprise, he found that his motorcycle was flying! I didn't want to fly just now, but now I don't want to fly but I fly, but I fly sideways!
He couldn't control the motorcycle at all, his body separated from the motorcycle, spun a few times in the air, and then fell to the ground.
Boom!
The motorcycle crashed into a big tree on the side of the road, click! The branches of the big tree broke, but the motorcycle did not fall and was caught by the branches below!
The motorcycle went up the tree, and the old cannon rolled around the ground a few times, spit out a mouthful of blood with a wow, and fainted.
Later, Pan Ge opened his eyes wide and looked at this scene in amazement, the strangely shaped car had stopped, looking majestic.
"Damn, I'm chopping you!" Pan Ge was also stimulated to blood, and with the bright flaky object in his hand, he rushed towards the car.
However, after not running a few steps, he suddenly stopped again, and the driver in the car had just stopped and had climbed onto the roof of the car.
The meaning couldn't be more obvious, come on, you come up, you come up, Lao Tzu will surprise you!
There were no bullets in the gun, but the other party didn't know about it.
Pan Ge stopped, his legs began to tremble, the cut wound also began to hurt, and with a bang, the flaky object fell to his feet, and he wanted to turn around and run away, but he couldn't move his legs.
"Come on, you come up, Lao Tzu will open the meat with you!"
"You run, you just need to turn around and run, Lao Tzu will shoot at three points!"
Poof!
Pan Ge knelt on the ground: "Comrade, I was wrong, you let me go!" ”
At this time, the girl who was robbed in the back also ran over panting, and was very surprised to see this scene, and when she saw the person in the car clearly, her eyes widened, and she just wanted to shout something, and the police car came roaring.
The big caps got out of the car, looked at the scene, and couldn't help but smack their tongues.
"Comrade, which part of you are from?" A big cap asked.
"**Compound's." Qin Feng replied.
The big cap immediately stood in awe: "Thank you for your help, let's make a pennant later and send it to you!" ”
"Don't, don't do it, if there's nothing else, I'll go first, this car is a secret, don't make a noise."
"Yes, we know, military secrets."
Qin Feng looked at the girl who was staring at him blankly on the side of the road: "This female comrade, you must have been frightened just now, right?" Get in my car and I'll take you back. ”
