As a group of people walked into the tall and spacious production workshop, a scorching hot air hit their faces. The alloy melting furnaces were emitting red sparks. The large continuous steel casting production line below was ready. The long assembly line

, giant rolling mills and cutting machine tools are interspersed in the middle, and processing equipment stretches for nearly a kilometer!

This was the first time for the two military officials to see such a huge production equipment. Although they had visited Western countries many times, they rarely had the opportunity to see with their own eyes how steel was produced, and this level of automation was extremely high.

The production line is even more unfamiliar...

Zhu Bin pointed to the production line with pride and said: "The equipment in the entire steel production process, including steel-making furnaces, continuous casting and rolling production lines, bearings, and control equipment, are all designed by us, and Chapter 354

The Taishan-class battleship (II) was manufactured by the Germans, and the next phase of the expansion project, including the 5-meter extra wide and thick plate large rolling mill, will be manufactured by us. By then, China's steel industry will have achieved

True autonomy.”

5-meter wide and thick plates represent one of the top standards in the world's steel manufacturing industry. All large ships manufactured by major naval powers require the use of extra-wide and extra-thick steel plates. Currently, the earliest steel plates in the world are only

The 5230mm rolling mill built by the Lukens Steel Company in the United States in 1918 has not reached the level of the others. It is quite amazing to have the current production capacity of special steel plates with a width of 3500mm and a thickness of more than 250mm.

Chen Shaokuan and Jiang Baili obviously don't know much about specific metallurgical technology. But that doesn't stop them from knowing some macro figures. Chen Shaokuan, in particular, is very clear about the direct benefits brought by ultra-wide and ultra-thick steel plates, which are the primary guarantee for building larger ships.

, and the significance of the 5-meter-wide rolling mill is obviously great. If it is built as Zhu Bin said, it will become a large-scale construction capacity second only to the United States. Compared with the pitiful situation of China's annual steel production of less than 100,000 tons four years ago,

, what a big leap this is!

Steel plant manager Yu Mingyu stepped forward Chapter 354

The Taishan-class battleship (II) came and greeted a few people. I don’t know whether it was because of the heat or excitement. After roughly introducing the main equipment to them with a red face, he signaled to Zhu Bin: "It’s almost time.

.Shall we get started?”

Zhu Bin looked at the two bosses and saw that they had no other questions, and waved his hand vigorously: "Start!"

The three people came to the edge and turned on the electric switch together. They saw on the roof of the factory in front. A series of molten steel ladles that were constantly sparking slid along the track and were continuously poured into the casting mold protected by argon gas.

The forced water-cooling equipment cools down rapidly and begins to solidify. After secondary cooling by air-water mist, it takes shape.

That is, the rolled long shaft is transferred to the continuous rolling production line below. After pickling, grinding, and reheating, it enters the 500mm rolling mill, then enters the 350mm rolling mill, and finally rolls out a slightly thicker steel plate than the intended battleship keel.

After cutting and cooling, enter the next production process.

This production line directly supplies steel plates used by downstream shipyards. At the end of the continuous casting and rolling line, a large plasma cutting machine is added to directly cut out the required length and width according to the design standards, and then evenly polish and trim them.

A piece of keel steel plate that can be directly transported to the slipway and laid and welded is officially formed!

Watching as steel ingots weighing hundreds of tons are easily rolled into thin slices by thick rollers like kneading dough, the 150mm thick steel plate is still as smooth as tofu cut by a knife under plasma cutting, and the polished surface is discernible.

, with almost no burrs visible, a piece weighing dozens of tons is placed in front of you. It has a heart-stopping charm!

Zhu Bin and others lined up behind the steel plate. After taking photos with the engineers, Chen Shaokuan walked around the steel plate and carefully touched the mirror-like cold steel surface with his white-gloved fingers. He couldn't help but feel excited.

. asked with warm eyes: "This kind of steel plate is stronger than the German KCN

How about a steel, wh steel, st52 shipbuilding steel?”

These two kinds of special steel are the top shipbuilding steels in the world today, representing the world's highest metallurgical achievements. But they are not as good as the technology in Zhu Bin's hands.

Zhu Bin said proudly: "The technology we use and the electroslag remelting smelting have higher purity than theirs, the alloy formula is more accurate, and at the same thickness, the tensile strength, yield strength and elasticity resistance are at least higher than theirs.

25% more, coupled with our welding technology and overall design, we can get higher protection capabilities and more space at a weight one-fifth lower than theirs. And in terms of anti-rust and anti-magnetic

Even more superior."

"Okay! That's good!" Chen Shaokuan was overjoyed. Jiang Baili couldn't help but look askance at him. It can be better than the special steel smelted by the Germans. What kind of concept is this!

Zhu Bin didn't dare to go too far. In fact, this was just a matter of conditions and he had to follow the trend. In other words, his idea was to directly use space alloy to build it, which would directly save more than half the weight and increase the weight by at least several times.

With its defensive capabilities, the battleships that come out are called indestructible!

And even if you don't use that, just add rare earth trace elements and ultra-pure elements based on German Krupp armor steel, use a graphite single crystal crucible, and add ultra-pure alloy materials made by a high-temperature plasma induction melting furnace of up to 2 degrees.

It is also enough to reach high-strength steel plates that they can only dream of.

Jiang Baili couldn't help but ask: "As you said, to what extent will the new battleship we build be superior?"

Although Chen Shaokuan was familiar with the model data from four years ago, he also knew that Zhu Bin must have other ideas for improvement, so he looked at him eagerly, hoping to get the answer.

However, Zhu Bin dragged Chief Designer Ye Zaifu over to explain on his behalf. Chief Engineer Ye did not refuse, and immediately explained with excitement: "Our design of this battleship is superior to any other in the world today. We draw on the excellence of designs from various countries.

, combined for my use, I designed a length of 230 meters and a width of 35 meters, standard 350

A brand new giant ship with a displacement of 00 tons! The main armor belt adopts the German dome armor design, with a maximum side armor of 350mm and a horizontal armor of 150mm. Even without considering the higher bulletproof capabilities of our armor, it still has a total defense of 500mm.

.And no cannonball in the world can penetrate it!"

"In addition, our upper deck and lower deck armor are separated, and each layer is lined with 50mm stone fiberboard. No matter what angle the artillery fire is fired from, it must penetrate at least 460mm thick armor to reach the interior.

It also has a power cabin and ammunition depot, and these main parts also have their own armor."

"And our turret, because it mostly uses stone fiber and titanium alloy composite armor, has a thickness of 460mm and is only half the weight of ordinary armor steel. Therefore, it is lighter, the motor has more workmanship, and the command tower is also stronger.

Safer for the entire battleship crew!"

"In addition, our self-designed pressurized steam boilers and high-temperature gas turbines can provide 30% more power than similar products in the world under the same volume of equipment. After correspondingly reducing the size, the extra space can be added to install diesel engine auxiliary power.

, can obtain a strong power of 15 horsepower, and enable the battleship to reach a high speed of 33 knots. These data cannot be achieved by battleships from all countries!"

Ye Zaifu was gesticulating while talking, and the professional terms and data he kept spitting out made people dizzy. With such a tonnage and such defensive power, it is "impenetrable" and "indestructible". Is this thing intended to create a kind of sea fortress?

Can’t do it?!

However, who doesn’t like a truly powerful guy? I’m just afraid that he’s not strong enough, or that he does too much!

"So, how about the armament and firepower?!" We can only defend but not attack, which is not possible. The Japanese "King Kong-class" battleship was sunk. This is a lesson learned from the past!

Ye Zaifu seemed to think about it carefully. He nodded vigorously and said: "I should say, very strong!"

He calculated with his fingers: "We once introduced the American mk1 406mm naval gun technology, and later obtained the German design concept and some British and Italian technologies, and salvaged and studied the Japanese 203mm naval gun

gun technology, integrated and designed its own 406mm

The main gun has a caliber of 45 times. It can fire 2 rounds per second and uses 1220kg armor-piercing projectiles. It can hit a distance of 36,750 meters and can reach a theoretical armor-piercing capability of 452mm within 2 yards!"

"So powerful!" Even Chen Shaokuan couldn't help but exclaimed. With such a rate of fire, such a distance, such armor-piercing ability, coupled with powerful defense, it can be said that the "Nagato-class" battleship of Japan was completely defeated.

Ah! If we build two ships and pull them out, we dare to fight them directly with the main guns!

Ye Zaifu said happily: "That's not all! We equip the battleship with a twin-mounted 127mm

The 45 times high-level dual-purpose gun has a greatly increased range while maintaining the original rate of fire. 12 automatic ammunition supply turrets are displayed on both sides and in front of the command tower, with 1 twin-mounted anti-aircraft gun and 8 30mm 6-tube close-in defense gun systems.

Create a maritime anti-aircraft turret fortress that, combined with cruisers and destroyers, can withstand the impact and bombing of hundreds of aircraft groups! In the case of insufficient aircraft carriers, it still has strong survivability that is difficult to destroy!"

Even Chen Shaokuan had never heard of these things. There were so many advanced things that he, a naval weapons expert, had to think of making up lessons.

Jiang Baili couldn't help but admire: "That's great! I didn't expect that our country's military level has improved to such an extent in a few years! So, when will this kind of battleship be built?"

"It will take at least three years!" Ye Zaifu spread his hands and said helplessly, "This kind of thing cannot be rushed. Even if we work in three shifts, it will take at least 18-20 months to complete the hull manufacturing.

It will take another 4-6 months to debug and improve, and this is already the fastest."

"Three years!" Jiang Baili and Chen Shaokuan looked at each other, frowned, and sighed unwillingly, "I just don't know if the Japanese will wait until then to start the war! Otherwise, until then, we can only use what we have

The ships are fighting with them, it’s not safe!”

Jiang Baili has long judged that the Japanese may start a war within two years. They cannot see the complete unification of China's military and political affairs, and they do not want a powerful force like Zhu Bin to rise rapidly. If political blackmail cannot succeed, they will definitely resort to military suppression.

.If the recent earthquake had not had a serious impact on them, hundreds of thousands of Japanese troops would have entered the pass within a few months!

Zhu Bin scratched his head and sighed: "There's nothing we can do about this! I've tried my best, and it's incredible to be able to do this. Now I can only thank God for helping us a lot and letting the little devil hold it back first."

It’s hard to hold back and give us enough time to prepare for war. As long as we can delay it for two years, we won’t be afraid of him pricking us!"

"Two years? I hope so." Jiang Baili became worried when he thought of this, and asked, "Does this kind of battleship already have a name?"

Chen Shaokuan chuckled and said: "Hanchen had already decided four years ago. The battleship's class code name will be called 'Taishan'!"

"Taishan-class battleship! How many do you plan to build?"

Zhu Bin spread his hands and said: "Five Mountains! There should be at least five ships. But we can only build two ships in the first batch. Our industrial production speed cannot keep up. The second batch, hehe."

Two ships are actually enough to deal with the current Japanese navy. The quality of these ships is very poor, and their tactics are completely different. If they fight, they may have to recreate the dizzying scene of bombardment from 20 to 30 kilometers away in the dark. With their powerful strength,

Electronic technology equipment has many advantages.

The requirements for industrial level in battleship manufacturing are all-round. First of all, there is no way to fully understand the design capabilities without many years of accumulation. As far as the world is concerned, no country dares to say that the battleships they design are perfect, including the latest ones.

Old British.

Secondly, manufacturing capabilities. You must be able to produce high-strength steel plates and armor steel with stable quality in large quantities. Not just one kind, but at least three or even more. In this aspect, in addition to formulas and smelting equipment, large steel rolling equipment, cutting

Equipment, welding equipment, and heat treatment equipment are all big. You can count on your fingers the number of countries in the world that can manufacture a complete set of equipment. Japan only relies on buying them. In terms of comprehensive strength, perhaps only Germany and the United States are qualified.

During construction, large slipways, gantry cranes and welding equipment, as well as key skilled workers are required to ensure quality and speed. Japan is also not good at this, let alone China. Even Zhu Bin uses technology to make up for it to the maximum extent.

, and spent hundreds of millions of dollars to hire senior skilled workers from various countries as masters. The apprentices they brought out could barely fill a few shipyards, and they started working on two battleships at the same time.

Thirdly, equipment supply capacity. Key boilers, steam turbines, diesel engines, generators, propellers with a diameter of 6 or 7 meters, high-strength spindles, large machine tools that need to be used, etc. are all constraints and are indispensable. 5000

Hydraulic presses with a ton or more, or even 10,000-ton hydraulic presses and die forging machines are also necessary, but there are still very few of these that can be manufactured.

Finally, and the most critical condition, naval personnel. At least one or two thousand technical personnel on a battleship need to be responsible for thousands of types of equipment. Once put into combat, it will be the coordinated operation, efficiency and fit of one or two thousand people.

How, is directly related to the

The level of combat effectiveness. The so-called century-old navy actually mainly refers to this aspect. Although China has been building its army for half a century, it has been declining in the past forty years, and Zhu Bin's fleet is all made up of young people.

, the level remains to be seen!

Of course, Zhu Bin has some trump cards that he has not revealed. Currently, the only shipyard in China that can build such a large battleship is the Guzhenkou base, followed by Shanghai Shipyard and Qingdao Shipyard, which are also building 50,000-ton slipways, and Chongqing and Wuhan

Shipyards can build keel modules, which can speed up the process accordingly. But the problem is that it will take at least one or two years for these shipyards to mature!

Of course he can't wait, but his biggest hope is the hidden cave fully automatic production base! There, a total of ten 500-meter slipways have been excavated, plus 2 kilometers of floating platforms on both sides.

Continuous construction of production lines, as long as the steel plate materials and equipment can keep up, there will never be only two ships in the future!

After suppressing the thoughts in his mind, Zhu Bin suggested to the two of them: "Are you two interested in taking a look at the test of our new naval gun?"
Chapter completed!
