What, flange?

The flange is a kind of ring plate, with some screw holes, vertically welded to the end of the steel pipe, the two steel pipes are butted together, and then the two flanges are screwed together, and the docking work is completed, which can be seen in various pipeline places, especially the connection places of pipeline switches.

Oil pipelines can also use flanges, but the cannon barrel is really the first to install flanges!

Think about the smooth barrel of the gun, with a flange every other section, that scene is so interesting, it really becomes an oil pipeline.

Mr. Qin fooled Dr. Bull like this, okay?

Unexpectedly, Dr. Bull actually thought about it seriously!

The domestic industrial level of Yilak is too low, and it is impossible to hire welders with too good skills, this kind of complex operation, not to mention the local welders can do, if you invite welders from developed countries, you may leak secrets! So......

Instead of using this complicated welding method, it is better to use a simple flange, after all, this kind of one can be assembled when you take it back, which is much simpler!

"Okay, then use the flange!" Dr. Bull nodded.

The big guys were stunned.

I had just argued with this Dr. Boole for a long time, and the other party insisted on welding, and now, Mr. Qin said the welding process, and the other party felt that it was difficult, and actually agreed to use the flange again! I knew that we would have made a fuss, and let this Dr. Boole retreat, so that there would be no need to bother Mr. Qin!

Qin Feng smiled, he could sell the flange method, because he knew that the Babylonian cannon made by Dr. Bull used the flange installation method, because there was no suitable welding method in Yilak, so in desperation, he could only use the flange.

In fact, the installation method of the flange is also very good, as long as the flange can be accurately welded, and then rely on the various grooves on the disc surface, it should be able to ensure that the internal gas will not leak out, and the caliber of 800 mm is also large enough, so that people can drill in, polish the gap between the joints, and prevent accidental friction when the shell passes through.

Looking at the big guy's surprised gaze, Qin Feng smiled: "Please rest assured, we will guarantee a high enough precision, and the flange fixing can also ensure the quality." ”

"Okay." Dr. Bull nodded.

That's it.

"Dr. Boole, do you want to rest next? We'll have a dinner party in the evening......" Qin Feng sent out an invitation.

Dr. Bull shook his head directly: "I won't attend any bullshit banquet, it's a waste of time and life!" My time is spent on work, and in the future, I hope to stay here and watch the manufacture of three electroslag remelted steel pipes, when are you going to start? ”

"We need to coordinate the ingredients, it may take a few days, and you are sure you don't need to rest?"

"No, can you weld the flange now? I'm going to look at the flange weld and test the strength of the weld. ”

"Okay, Zhou Gong, you help coordinate." Qin Feng handed over the matter to Zhou Minghui.

Zhuang Shuren was a little embarrassed on the side, after all, he was also one of the accompanying technicians, and now, what if he stayed? Or do you want to leave with Mr. Qin?

"Zhuang Gong, we need to coordinate a batch of electroslag remelting steel, this needs your help, go, go to the office with me."

Zhuang Shuren nodded: "Okay." ”

In order to support the construction of the factory in the development zone, the infrastructure here is very good, the telephone in the office of the steel plant can be called long-distance, Zhuang Shuren made a long-distance call in the office, and negotiated with the second machine factory for the production and transportation of 50 tons of electroslag remelted steel.

Walking on the road, Zhuang Shuren couldn't help but ask: "Mr. Qin, you are so powerful, you know the process of welding electroslag remelted steel and other steels." ”

Qin Feng smiled: "This craft is for foreigners, just listen to it." ”

Just listen to it? Zhuang Shuren suddenly had a stirring in his heart, could it be that Mr. Qin was foolish? What if Dr. Boole takes it seriously and goes back to the experiment?

As if knowing what he was thinking, Qin Feng continued: "This welding process is very difficult, if it fails, it must be that the welder's level is not at home. ”

Zhuang Shuren's heart was cold.

"Mr. Qin, I will give you priority in production, and within three days, I will definitely be able to send the steel over." Put down the phone, Zhuang Shuren assured.

"Well, when these two batches of orders are completed, we will immediately change the mold and produce 200 mm inner diameter seamless steel pipes for you." Qin Feng said.

Zhuang Shuren nodded: "With your technology, the price of this seamless steel pipe produced can also be reduced by a large margin, so that the army should be able to purchase it." Zhuang Shuren is full of confidence in this.

They have already built a prototype cannon and have undergone many shooting experiments, but the troops have never placed an order.

There are many reasons, and the price is an important factor in it, the manufacturing process of this gun is complicated, the price is high, and the troops look at the price and feel that they cannot afford to purchase it.

Qin Feng shook his head.

"Mr. Qin, do you think what I said is wrong?" Zhuang Shuren was stunned for a moment, what did Mr. Qin mean by shaking his head?

"The problem with this gun is not only the price, but also the mobility." Qin Feng said: "If you can't solve the problem of mobility, I'm afraid the troops are still unwilling to procure." ”

The advantage of towed artillery is that it is cheap, the disadvantage is that it is slow, slow to maneuver, slow to deploy, and in a modern battlefield, this will not only lead to untimely artillery support to the front line, but may even be covered by enemy fire.

"We know the flaws of maneuverability, so we also have a version with a tracked chassis." Zhuang Shuren explained.

"With a crawler chassis, it's too expensive." Qin Feng said: "The army will not purchase. ”

In fact, the 203-mm guns equipped by the United States and the Soviet Union all use tracked chassis, although there is no turret, and the artillery has to be loaded outside, but after all, it can act on its own, and its mobility is much higher than that of towed artillery.

The 203-mm guns engaged in the country are mainly towed, after all, the self-propelled ones are too expensive, and the troops cannot afford to use them, but the towed ones are too poor in mobility and too slow to deploy, which leads to contradictions.

"Yes, Mr. Qin, you're right." Zhuang Shuren's face was slightly ugly: "You can't have both fish and bear's paws!" ”

"Why can't you have both? As long as you use your brain and think of a way, you can still find a solution. Qin Feng said.

"Mr. Qin, please speak!" Zhuang Shuren's eyes lit up.

"Actually, you only need to install an engine on the gun rack with various operating mechanisms, including the steering wheel, and that's it." Qin Feng said.

"Isn't that a self-propelled gun?" Zhuang Shuren asked.

"Of course not." Qin Feng shook his head: "This kind of artillery usually relies on cars to tow, and only when it travels short distances, that is, when it enters the position, it will use its own power, so its engine does not need too much horsepower, if you don't dislike it, the 20-horsepower single-cylinder diesel engine produced by our Pingwang Motorcycle Factory can be." ”

What a spectacular scene a cannon suddenly emitting black smoke should be, Qin Feng was looking forward to it a little at this time.

"This engine is mounted in front of the gun carriage and does not directly drive the tires, but drives the hydraulic pump, which can drive not only the hydraulic motor on the gun wheel, but also other mechanisms, such as the deployment of the gun carriage, the deployment of the hydraulic support mechanism, and even the loading of shells." Qin Feng said: "In this way, the time for our artillery to enter and leave the position can be greatly shortened, and at the same time, it will not increase the cost too much." ”

Zhuang Shuren's eyes lit up.

Self-propelled artillery, that is, the artillery is carried on a self-propelled chassis, it can be tracked or wheeled, it is highly mobile, it hits and runs, but it is expensive, towing the artillery, hanging on the truck to move forward, the structure is simple, the price is cheap, but the mobility is poor.

Now if we want to combine the advantages of the two, we can make such a compromise artillery: it is usually towed by trucks, and when entering and leaving the position, it relies on its own power, the price is not high, and the performance is excellent.

In fact, there is already this type of artillery in the world, that is, the FH77 howitzer developed by the Swedes, of which Type A has no reputation for its own use, and Type B is an export model that is publicized to the outside world, but the research and development of Type B has been a matter of 87 years, and artillery experts in the East have not noticed this way.

At this time, Qin Feng put forward this plan, and Zhuang Shuren was immediately eye-opening, but after thinking about it, he was still a little embarrassed: "Mr. Qin, our second machine factory is making artillery, and we are not good at the research and development of this auxiliary device!" ”

"If you don't have this technology, you can leave it to us to develop it." Qin Feng said: "Our people from Pingwang Motorcycle Factory just haven't had anything to do recently. ”

The research and development of the Mengshi car is nearing the end, and it is currently in the testing stage, and Xing Fuqiang and others with strong hands-on ability have nothing to do, so they just find something new.

This will not only allow Pingwang Motorcycle Factory to open up a new business and make more money, but also contribute to the development of the military industry in the East.

After all, Qin Feng knows the direction of history, after the 203 mm gun was developed, the army did not place an order, and the entire project was mothballed, so that until 2023, the 203 mm howitzer shined in the war, and the military decided to take out the dusty project and re-develop it, which was delayed for twenty or thirty years.

Now, since Qin Feng has encountered it, he has to push it and give the army the most suitable choice, so that the army can see the excellent performance of this artillery, so that it can be installed in the army, and save the blindness in the future.

Now that you have been born again, you have to do something meaningful.

"Okay, Mr. Qin, after we apply for the project, the superior will allocate the R&D funds, and when the time comes, the funds for this self-contained device will be handed over to your Pacific Group, and you will develop it."

Qin Feng nodded: "Well, we will definitely not let you down, but when you apply, don't say that it is subcontracted to us." ”

"Why?"

"If we knew that we were giving R&D, the army would definitely not give R&D funds."

Zhuang Shuren was stunned for a while.

It was soon evening, and Kamal, who had slept well, was refreshed and walked briskly to the small cafeteria, where a sumptuous dinner was ready.

The chefs are also very good at making these delicacies, such as braised beef, lamb with green onions, and stir-fried chicken...... The plates of food are bubbling with a fragrance, and Kamal also feels his index finger move, although they are also good at making these ingredients in China, but they definitely do not have this kind of fragrance.

It's so fragrant! How is this done?

"Mr. Qin, can you invite the chef here to our country?" Kamal spoke.

"I don't count this, you have to ask the chef himself, come, let's have a drink first." Qin Feng raised his glass: "It is a great honor for Mr. Kamal to come to our Pacific Group Iron and Steel Plant from thousands of miles away, come, let us pay tribute to Mr. Kamal." ”

"In this war, the East has given us great support." Kamal said: "Without the East, there would be no great victory for us, come, toast to our friendship!" ”

Now, the flames of war have burned in their land, and the enemy has come in, but they still have to slap their swollen faces and make fat people, saying that they are the victors, this attitude is really speechless.

"That's right, come, a toast to our friendship!"

After three glasses of wine, the relationship between the big guys will be better.

"Mr. Qin, if you have the opportunity, you are welcome to visit our Yilak as a guest, you have formed a deep friendship with Eritrea in the war, and you will definitely be able to establish a good relationship with us, I heard that you have mined ore in Eritrea, we have a lot of Yilak, you are welcome to invest in our Yilak."

"Yes, definitely, definitely." When talking at the wine table, you can boast about anything, but as for whether to act or not, maybe you will forget it all after drinking.

Just as the big guy was drinking and talking, a discordant voice suddenly sounded outside.

"Why don't you let us in? We are also your most honored guests! ”

"That's right, these equipment of yours are all provided by us, and our technical consultants are also invited by you, and you have a banquet, but you don't invite us to participate?"

Islanders!

Wang Fang's face changed suddenly, their cooperation with Yilak is secret, and it must not be known to the outside world, so from the time these people entered the factory to the present, only the most core people have been able to receive Kamal and others, and as for the dinner party, it is also to avoid being too ostentatious, and it is easy to attract attention when going to the hotel outside.

These consultants are supposed to have been arranged to dine at the only Japanese restaurant in the development zone, so why did they come back and come here for a banquet?

"Mr. Qin, what should I do?" Wang Fang's gaze looked at Qin Feng.

Qin Feng smiled: "It's all come to this, just let them in." ”

After speaking, Qin Feng looked at Kamal again: "Mr. Kamal, haven't you always been looking forward to selling the iron ore?" How about taking advantage of this opportunity to sell iron ore to the islanders at a high price? ”

Kamal's eyes lit up: "Okay." ”

"Then it's up to my ......"

Ishino Yutsu and others have come back from the Japanese restaurant, the food is not bad, so a few people are a little homesick, it is said that the technology here has been mastered, they should also go back, but, they don't want to go, this is not because of more travel subsidies, but they found that this factory is very interesting, they stay here, they can get a lot of things.

When they came back, they took a shortcut, passed by the small cafeteria, and then they found that something was wrong, there was a guard outside, and the aroma inside was particularly strong, and it must have been a banquet for a big man, so they asked to go in, but they were stopped at the door.

Ishino Yutong had a proud face: "You dare to stop us consultants, believe it or not, let's leave now, if something goes wrong with your production line, don't blame us!" ”

At this moment, a familiar figure came out of it.

"Mr. Ishino, and other Mr. Advisors, please come in." Wang Fang had a smile on his face: "Don't worry about our guards, they're just ignorant." ”

"Hmph." Yumito Ishino made a sound from his nose, and then strode inside, saying as he went, "What kind of guests are being invited here?" Is it more noble than our status? Hey, why does this person have a mustache, is it ......?"

"Mr. Ishino, it's better to come early than to come at a good time, come in, dine together, and let me introduce you, this is Mr. Kamal from Yilak."

There's nothing to hide, after all, a figure like Kamal is out on the outside, often making a speech or something, and these islanders can easily recognize it, so it's better to admit it generously.

Kamal? The man in charge of oil and minerals in Yirak? Ishino Yutong was suddenly a thrill in his heart.

What did this man do in the East? There are no officials to accompany you, go directly to the steel plant here!

It's definitely not an oil transaction, the oil transaction in the East can only be done by state-owned enterprises, that is, mineral trading! This is a steel mill, so what else is there to say, it must be iron ore!

Thinking of this, Ishino Yutong suddenly became excited.

The Orientals need iron ore, and their island countries also need iron ore! The island country is poor in resources, and almost all the resources needed are shipped by sea, and the island people buy mines all over the world to make up for the lack of resources, but they have not yet reached out to Yilak.

If they can get iron ore from Yirak, then they have another source of iron ore.

"Mr. Kamal, it's a pleasure to meet you." Yu Ishino said in English, not fluent.

English is an international language, and a high-ranking official like Kamal naturally speaks English, and the big guy is just communicating in English, but Ishino Yutong's English pronunciation is the most non-standard, and you have to carefully identify it to know what he is saying.

"Who are you?" Kamal questioned.

"I'm the representative of the island nation of Kobe Steel, and my name is Yumichi Ishino." Yumito Ishino said: "Mr. Kamal, we Kobe Steel are the world's leading steel companies, and our company has been buying iron ore from all over the world at high prices, and we can offer the highest price in the world!" ”

Kamal was excited in his heart, sure enough, what Qin said was no problem, he could sell the iron ore to them, and moreover, he could sell it at a good price, now, according to the plan!

Kamal's face was embarrassed: "Mr. Ishino, I'm sorry, we have already negotiated a business with Dongfang. ”

"Yes." Qin Feng's face was displeased: "Mr. Ishino, you come in to join the banquet, we welcome you, but if you have another purpose, then please leave." ”

Qin Feng drove people away!
