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.

This Spring Festival holiday also made Liu Tao spend a relatively smooth time.

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 to develop an LNG ship.

LNG ship is a special ship for transporting liquefied gas at a low temperature of minus 163 degrees Celsius. It is a "super refrigerated truck at sea" and is known as the "crown jewel" of the world's shipbuilding industry.

At present, the world's first LNG ship builder is Japan.

LNG ships are also very profitable for civilian shipbuilding.

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

The countries that can build LNG ships can be counted on one hand. This kind of ship can be said to be a "three highs" product with high technology, high difficulty and high added value. LNG storage tanks are 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 for building liquefied gas ships.

Of course, the MOSS type is only one type of LNG ship, and there is also a relatively new type of membrane LNG ship.

The liquid cargo tanks of membrane ships are divided into GTT N0.96 and Mark III according to the different insulation types and construction methods. The insulation form of GTT No.96 is an insulation box; the Mark III type is composed of insulation boards and rigid insulation materials.

GTT No.96 has higher requirements for hull construction technology than Mark III. Whether in terms of precision control or welding requirements, mastering the construction requirements of GTT No.96 basically means mastering the construction technology of Mark III.

In the welding of the main and secondary layers of the liquid cargo tank INVAR, GTT No.96 can use automatic welding in large quantities, and the welding quality is easy to control, while Mark III uses more manual welding, and the welding quality is not easy to control.

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

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

Liu Tao wants to develop LNG ships, so he naturally wants to avoid the French patents.

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

As for whether the French will reduce the patent fee income, it has nothing to do with him.

Why can the French live comfortably, while the Chinese have to work hard?

To avoid the French patent, you have to come up with a material that is different from the material invented by the French. As long as the material formula is different, or the physical properties are different, whether it is better or worse than the French material, it is a new material.

Yes, as long as you create new materials, innovate in shape and process, you can perfectly avoid all patents.

Even in the future, with these new patents, you can collect patent fees from other shipyards.

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

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

Liu Tao is in the laboratory, exploring new materials.

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

According to public information, Liu Tao made a 20-centimeter-long piece of material.

Holding this steel rod in his hand, he looked at the virtual panel:

[Item: Invar Steel Rod]

[Manufacturer: Liu Tao]

[Item Level: LV1 (Incomplete, repairable)]

[Upgrade Points: 50]

[Item Status: Incomplete, analyzable]

"Sure enough, the French are not good people. The information published cannot produce qualified Invar steel." Liu Tao looked at the two words "incomplete" on the virtual panel and couldn't help complaining.

But it's normal to think about it, because Europe and the United States are of the same nature. They have built their own knowledge 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 the pit.

Because their books are 70% true and 30% false, or even 80% true and 20% false, which makes people unable to distinguish the true from the false, and then foolishly choose to believe, and both feet suddenly fall into the knowledge trap, and they don't know if they are trapped to death.

At present, only the Japanese and the Soviets in the world have summarized their own intellectual rights after paying a painful lesson.

This is also the fundamental reason why the Japanese and Soviets are not inferior to Europe and the United States in the field of science.

China also paid a high tuition fee and shed blood, and finally waded out its own path.

Liu Tao followed the same steps and made 10 Invar steel rods.

"System, repair!" Liu Tao muttered in his heart.

Swish, swish, swish~~

A series of faint lights flickered.

The Invar steel rod in his hand seemed to have undergone subtle changes, but it seemed that 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 believed in the system.

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

"System, analyzation!" Liu Tao muttered in his heart.

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

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

The performance of Invar steel is very outstanding. 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 the manufacture of precision instruments, Invar steel is widely used in the manufacture of precision instruments and measuring equipment due to its high precision, low expansion coefficient and good mechanical properties, such as various instruments, telescopes, measuring instruments, etc.

For example, electronic communication equipment, Invar steel is also widely used in the field of electronic communications, such as for the manufacture of 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, due to its excellent low-temperature performance and strength, Invar steel is used to manufacture important parts in aerospace vehicles such as aircraft and rockets.

For example, in the nuclear energy field, 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 field, Invar steel is mainly used to manufacture high-temperature, high-pressure pipelines and 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.

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

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