The rise of a great power: starting with military industry

Chapter 791 Yinwa Steel

finally.

Liu Qi and Qian Huaqiang still saw their wives and children, and took them home the next day.

As for how they dealt with their affairs, Liu Tao was too lazy to ask.

Out of sight out of mind.

Liu Tao also had a relatively smooth Spring Festival holiday.

After the seven-day National Day holiday, Liu Tao went to Yangcheng Shipyard a few days after returning to Panshan Group headquarters.

This time he came to Yangcheng Shipyard, he was going to develop an LNG ship.

LNG carriers are special ships that transport liquefied gas at a low temperature of minus 163 degrees Celsius. They are a kind of "super refrigerated truck at sea" and are known as the "crown jewel" of the world's shipbuilding industry.

Currently, Japan is the world's largest LNG ship builder.

LNG ships are also a very profitable type of civilian shipbuilding.

Currently, the market share of LNG ship construction is mainly in the hands of Japanese, European and American shipyards.

The number of countries that can build LNG ships can be counted on one hand. This type of ship can be said to be a "three-high" product with high technology, high difficulty and high added value. The LNG storage tank is a special structure independent of the hull. In the design of this ship, the main factors considered are materials that can adapt to low-temperature media and the handling of volatile or flammable materials.

The MOSS spherical tank here is made of aluminum-4.5% magnesium alloy 5083, and is also a common storage tank currently used in the construction of liquefied gas carriers.

Of course, the MOSS type is just one type of LNG ship. There is also a newer type of membrane LNG ship.

The cargo tanks of membrane ships are divided into GTT No.0.96 and Mark III according to the insulation type and construction method. The insulation form of GTT No.96 is an insulation box; the Mark III is composed of insulation board and rigid insulation material.

The GTT No.96 has higher requirements for hull construction technology than the Mark III. Whether in terms of precision control or welding requirements, mastering the construction requirements of the GTT No.96 basically means mastering the construction technology of the Mark III.
In the welding of the main and secondary layers of the liquid cargo tank INVAR, the GTT No.96 type can use automatic welding on a large scale, and the welding quality is easy to control, while the Mark III type uses more manual welding, and the welding quality is not easy to control.

Currently, no matter which shipyard builds LNG ships, it has to pay high patent fees to the French.

Because the core technology here has long been monopolized by the French.

Liu Tao wanted to develop LNG ships, so naturally he wanted to avoid the French patent.

After all, after working so hard to build an LNG ship, the profit is not as much as the patent fee paid to the French. It really makes people cry without tears and want to vomit blood.

As for whether the French will reduce their patent royalties, that is none of his business.

Why can the French live a comfortable life while the Chinese have to work so hard?
In order to avoid the French patent, we have to develop a material that is different from the material invented by the French. As long as the material formula or physical properties are different, whether it is better or worse than the French material, it is a new material.

Yes, as long as new materials are created, styling innovations are made, and process innovations are made, all patents can be avoided perfectly.

Even in the future, relying on these new patents, we can charge patent fees from other shipyards.

Liu Tao did not build a ship model because this was the second step. The first step was to master special materials.

It just so happens that the Yangcheng Shipyard has its own construction laboratory.

Liu Tao is in the laboratory, exploring new materials.

His approach is not complicated, which is to explore the material formula based on the original basis.

According to public information, Liu Tao produced a piece of material 20 centimeters long.

Holding the steel rod in hand, looking at the virtual panel:

[Item: Invar Steel Rod]

【Manufacturer: Liu Tao】

[Item Level: LV1 (damaged, repairable)]

[Upgrade Points: 50] [Item Status: Incomplete, can be analyzed]

"Sure enough, the French are no good. The information released cannot produce qualified Invar steel." Liu Tao looked at the two words "incomplete" on the virtual panel and couldn't help but complain.

But think about it, it's normal, because Europe and the United States are of the same nature, they have built their own intellectual hegemony.

If you just read books, learn about Europe and the United States, and believe in Europe and the United States 100%, you will definitely fall into a trap.

Because their books are 70% true and 30% false, or even 80% true and 20% false, making it difficult for people to distinguish the truth from the false. Then they foolishly choose to believe them, and their feet suddenly fall into a knowledge trap, without knowing they are being scammed.

Currently in the world, only the Japanese and the Soviets have, after paying bitter lessons, concluded that they have their own intellectual property rights.

This is also the fundamental reason why the Japanese and Soviets are no worse than Europeans and Americans in the field of science.

China also paid expensive tuition fees and shed blood, and finally forged its own path.

Liu Tao followed the same steps to make 10 Invar steel rods.

"System, repair!" Liu Tao said silently in his heart.

shhhh~~
Tiny rays of light flickered.

The Yinwa steel rod in his hand seemed to have undergone slight changes, but it also seemed as if nothing had changed.

Look at the virtual panel again:

[Item: Invar Steel Rod]

【Manufacturer: Liu Tao】

[Item Level: LV1 (0/10)]

[Upgrade Points: 80]

[Item status: intact, analyzable]

Seeing the word "intact", Liu Tao smiled. He still had great confidence in the system.

From the beginning to now, there has been no mistakes in the item upgrade panel.

"System, analysis!" Liu Tao muttered to himself.

In an instant, the actual formula and manufacturing process of Invar steel material appeared on the virtual panel.

Liu Tao's mouth curled up slightly. Because of its extremely low thermal expansion coefficient, Invar steel can maintain a fixed length over a wide temperature range, making it the best material for LNG ships.

The performance of Invar steel is excellent. It has high strength and good plasticity, good corrosion resistance, excellent low-temperature performance and extremely small expansion coefficient, which makes it useful in many fields.

For example, in precision instrument manufacturing, Invar steel is widely used in the manufacture of precision instruments and measuring equipment, such as various meters, telescopes, measuring instruments, etc. due to its high precision, low expansion coefficient and good mechanical properties.

For example, in the field of electronic communications, Invar steel is also widely used. For example, it is used to manufacture precision components in communication satellites and communication equipment to ensure that the equipment can maintain stable performance under various temperature conditions.

For example, in the aerospace field, because Invar steel has excellent low-temperature performance and strength, it is used to manufacture important components in aerospace vehicles such as airplanes and rockets.

For example, in the field of nuclear energy, Invar steel is used to manufacture important structures and components in nuclear reactors due to its good corrosion resistance and high strength.

In the petrochemical industry, Invar steel is mainly used to manufacture high-temperature, high-pressure pipelines, valves and other equipment. Its good corrosion resistance and high strength can ensure the safe and stable operation of the equipment in harsh environments.

In the field of medical devices, Invar steel is also used to manufacture medical equipment and instruments, such as scalpels, dental tools, etc. Its excellent mechanical properties and high precision can ensure the safety and reliability of the equipment during use.

Invar steel is widely used in many high-temperature manufacturing fields due to its special physical and mechanical properties.

With this material formula, Liu Tao can easily earn hundreds of millions of dollars a year.
