King of Industry

In the office, Li Kejian and Qin Yang sat up straight after hearing what Zhao Guoyang said.

Obviously, these two leaders are still very concerned about the development status of the country's shipbuilding industry.

Zhao Guoyang sighed softly, and said: Old Li, Director Qin, you two should also know that with the development of the world economy, the speed of large-scale ships and deep-sea development of marine resource development will be further accelerated.

And this requires a large number of steels with special properties for the shipbuilding industry and marine industry.

Because of our late start, our country is far behind the international advanced level in terms of the production and research of special steel for the shipbuilding industry and marine industry.

In order to improve the level of our domestic shipbuilding industry, the improvement of special steel smelting is a big problem that our country has to face.

After Zhao Guoyang finished speaking, Li Kejian couldn't help but sighed slightly.

As a leading figure in the domestic industry, Mr. Li has always been very concerned about the improvement of the domestic steel manufacturing level, and he has also helped out a lot of ideas.

In recent years, although the total amount of domestic steel production has gradually leapt to the forefront of the world, in this respect, China is already a big steel country.

However, being big but not strong is the main problem in the domestic steel industry.

We must know that the conditions for a strong steel country are to have the world's leading production capacity and technical level, and to be able to produce high-performance, high-tech and high-added products.

While basically satisfying the domestic market, Huaxia steel production still focuses on high energy consumption and low value-added products, and most of the high value-added steel products still rely on imports. In Mr. Li's opinion, this is really not a good phenomenon.

In the shipbuilding industry, because of the large variety and quantity of high-performance special steel products required, it further highlights the lack of domestic steel manufacturing level.

At this time, Zhao Guoyang's narration just touched the bottom of Li Kejian's heart, which made him feel a little sad.

Qin Yang at the side might also see the melancholy of Li Lao, so he forced a smile and said: The problem that Researcher Zhao mentioned does exist. You are an expert in this field, I wonder if you can tell me in detail?

For example, what kinds of special steel materials are urgently needed by the shipbuilding industry and the marine industry; in terms of technology, how far is the gap between us and the international advanced level, and so on...

Now that the leader has spoken, Zhao Guoyang of course knows everything he can say.

After sorting out his thoughts, he slowly explained what he knew about the status quo of special steels required by the shipbuilding industry.

According to the current situation of our domestic ship production, the shortage of special steel products is mainly in the following categories... First, it is the low-temperature steel used by liquefied gas carriers.

Internationally, liquefied gas is mainly carried out by special transport ships for liquefied gas, including LPG (liquefied petroleum gas) ships and LNG (liquefied natural gas) ships.

The internationally accepted Code for Steel Materials and Welding stipulates the low-temperature ductile steel used for the construction of liquid cargo tanks and adjacent hull structures of liquefied gas carriers, including carbon-manganese steel and Nickel alloy steel with a temperature of -60~-196°C.

Among them, 9Ni steel is the most important steel type for the construction of self-supporting LNG ship storage tanks. It is a pity that there is no domestic steel manufacturing enterprise that can produce this kind of 9Ni steel plate for ships.

Zhao Guoyang sighed and said: With the enhancement of human awareness of environmental protection, the proportion of clean energy in international energy consumption will gradually increase, which will inevitably lead to a large number of applications of LPG ships and LNG ships. This requires a large amount of low-temperature steel, such as 9Ni steel and expansion steel. Alloy, etc.

Not one of our domestic steel manufacturing companies has the ability to mass-produce this type of low-temperature steel. If you want to manufacture this kind of liquefied gas carrier, this type of special steel can only be imported...

After hearing Zhao Guoyang's narration, Mr. Li, who is familiar with the situation of the steel manufacturing industry, sighed for a while.

Although Qin Yang is not particularly proficient in steel manufacturing, he is still sweating from hearing this.

Indeed, if what the researcher Zhao just said is correct, the prospects for the development of the domestic shipbuilding industry are really worrying.

Zhao Guoyang paused for a moment, then continued to speak: In addition to low-temperature steel, special steel that is often used in the shipbuilding industry and marine industry, it also includes ship plates for welding with high heat input, steel plates with high crack arrest performance, and steel plates with high crack arrest performance. Ultra-high-strength steel for offshore platforms.”

As far as I know, these special steels are rarely produced by domestic steel producers.

Speaking of this, Zhao Guoyang sighed and said: It is no exaggeration to say that if the domestic steel manufacturing enterprises cannot achieve a major improvement in the production level of special steel products. Our Chinese shipbuilding industry wants to take off. That's out of the question...

Hearing Zhao Guoyang's somewhat exaggerated words, Qin Yang was speechless for a while.

But when he saw Li Kejian who was next to him nodding approvingly, he could only force himself to accept the radical ideas of this young Researcher Zhao.

Zhao Guoyang seemed to think of something suddenly, and said again: Ah, by the way, Director Qin. There is another important type of special steel, I forgot to tell you.

Qin Yang was slightly taken aback, and then hurriedly said: Researcher Zhao, just say it, I'm listening!

Zhao Guoyang nodded with a hmm and said, The last special steel is corrosion-resistant steel...

Hearing the three words corrosion-resistant steel, Li Kejian seemed to be awakened, and soon regained his energy.

Corrosion-resistant steel? Is it stainless steel? Researcher Zhao, there seems to be a domestic company that can produce stainless steel, right?

Qin Yang should know something about this aspect, after listening to Zhao Guoyang's narration, he couldn't help interjecting.

Zhao Guoyang took a deep breath and explained: Director Qin is half right. This corrosion-resistant steel is indeed a type of stainless steel. It refers to steel that can resist corrosion in certain strong corrosive media. Stainless steel is just Steel resistant to corrosion in air or weak media.

To put it bluntly, stainless steel is not necessarily corrosion-resistant, and corrosion-resistant steel must be stainless steel.

Hearing this, Qin Yang slapped his head and suddenly realized.

After Qin Yang understood, Zhao Guoyang continued: In our country, according to the difference in corrosion resistance of various stainless steels, the specifications are set from 301 to 349.

But in fact, domestic steel manufacturers can only produce stainless steel in the range of 301~314.

In international shipbuilding, the performance of the corrosion-resistant steel required is at least 321. That is to say, in terms of corrosion-resistant steel, our domestic shipbuilding enterprises are completely dependent on imports...

Zhao Guoyang's narration made the two leaders, Li Kejian and Qin Yang, feel a little ashamed.

Indeed, as the department leaders of the Ministry of Machinery and Electronics Industry and the State Oceanic Administration, the two of them are responsible for leading the domestic shipbuilding industry.

The current lag of the industry has also put a lot of pressure on the two leaders.

Zhao Guoyang didn't notice the unnaturalness of Mr. Li and Director Qin. Since he mentioned corrosion-resistant steel, he had to explain more about the meaning of this special steel.

Director Qin, the reason why I specifically mention this corrosion-resistant steel is because it is an indispensable special steel for oil tankers. In the cargo oil tanks of oil tankers, the amount of corrosion-resistant steel accounts for 40% of the total steel consumption of ships. ~45%, which means crude oil corrosion resistant steel plate has a huge market demand.”

You know, as an important tool for international crude oil transportation, the number of oil tankers has been increasing every year. And the range is quite large...

As the leader of the State Oceanic Administration, Qin Yang is no stranger to the widespread use of oil tankers.

After listening to Zhao Guoyang's explanation, he nodded in agreement and said, I really understand a lot after listening to what you said, Researcher Zhao!

It seems that if we want to achieve a certain degree of success in this pilot project of the State Oceanic Administration and the Ministry of Machinery and Electronics Industry, we really have to start with steel companies first?

After Qin Yang finished speaking, Zhao Guoyang replied in a serious manner: It is true, Director Qin, the development of the shipbuilding industry is inseparable from the development of the steel industry. On this issue, I think the two leaders and departments, It’s totally conceivable.”

Zhao Guoyang explained in a calm tone: As we all know, the shipbuilding industry is one of the eight major industries in the world's steel consumption. Specifically, in China, the annual steel demand of the shipbuilding industry is at least between 2 and 2.5 million tons.

Among them, 80%-90% of marine steel plates are only the steel consumed by shipbuilding itself, not including steel other than shipbuilding, such as steel for building factories and equipment for shipbuilding. In this respect, the domestic marine steel market , is huge.

Hearing this, Qin Yang's eyes lit up, and he already understood what Zhao Guoyang meant.

Sure enough, Zhao Guoyang quickly continued: I think, since we want to start this pilot project of private shipbuilding, it's better to solve some of the special steel issues as a package.

In this way, we can gradually explore the path of private enterprises and get involved in the shipbuilding industry; at the same time, we can improve the level of our domestic steel production technology to a certain extent. It is really the best of both worlds!

Hearing this, Qin Yang rubbed his chin and nodded repeatedly: Well, yes! Researcher Zhao's idea can definitely be implemented, it is very feasible!

Seeing Director Qin gradually getting into the game, Li Kejian on the side glanced at Zhao Guoyang amusedly.

For this old Li, Zhao Guoyang didn't want to hide it, and he didn't feel ashamed at all when he glanced at him.

Zhao Guoyang calmed down for a while, and said with a straight chest: Director Qin, regarding the private shipbuilding pilot project you proposed, I am willing to recommend myself!

Oh? Self-recommendation? Could it be that Researcher Zhao owns a shipbuilding company? Hearing this, Qin Yang was puzzled.
