reborn in the fiery age

From the point of view of equipment, the 5500mm wide and thick plate rolling mill weighs more than 400 tons with only one rolling mill frame archway, the maximum diameter of the rolling mill back-up roll reaches 2400mm, and weighs 250 tons, and the total weight of the whole rolling mill exceeds 3000 tons.The total power of the main motor is over 20000kW, the raw material slab weighs 250 tons, and the maximum tonnage of the bridge crane used in the workshop is 400 tons.

The thickness of the steel plate produced by it can reach up to 400mm, which is more than 4 times that of ordinary rolling mills. It can be used as armor plate for aircraft carriers, battleships, tanks and other weapons.The width of the steel plate is 5300mm, which is more than twice that of ordinary rolling mills; the weight of a single steel plate is 2 tons, which is more than five times that of ordinary rolling mills. These specifications are far larger than those of small and medium-sized rolling mills.

Steel plates of this thickness are often high-tech and high value-added products, and are also important strategic materials with a wide range of uses.

Mainly used for large ships and large-diameter oil and gas longitudinal welded pipes of more than 10 tons, as well as weapon armor, structural steel for giant bridges, structural steel for offshore drilling platforms, containment shells for nuclear power plants, large dam gates, steel plates for high-pressure boilers in power stations, and shells for steelmaking blast furnaces , large oil and gas storage tanks, large mechanical structural steel, die steel, super high-rise buildings and other fields.

Therefore, once this kind of rolling mill is successfully researched, it will help break the blockade of foreign special steel products on my country, and will play an important role in promoting my country's oil, natural gas transportation, shipbuilding and national defense construction.

For the successful research of 5500mm extra wide and thick plate rolling mill, Sun Zujie is very confident and has a corresponding research foundation. The successful research of 4200mm extra wide and thick plate rolling mill in the 70s shows that Xia Guo has corresponding research capabilities.

The reason why there has been no progress for more than 20 years is, in the final analysis, a problem of state investment. As long as the money is given enough, it is very likely to take out a 5500mm extra wide and heavy plate rolling mill.

Of course, in addition to the domestic foundation, Xia Guo also has foreign aid. The Germans promised to assist Xia Guo in the development of corresponding equipment. one.

The investment in such a large project is astonishing. A large amount of Huayuan was invested, and the fruit was finally seen. In the year when the aircraft carrier returned to China, Yizhong finally cast the 400-ton rack necessary for the thick plate rolling mill, but how to pull it out? Getting to Liaodong is a big problem.

Air transport, sea transport, and road transport are not acceptable, and there are no large-scale trucks for rail transport.I have no choice but to continue to find a way to study the world's largest drop hole car with a load of 450 tons. The car has a total length of 70 meters and a self-weight of 202 tons. The department is also specially equipped with a test vehicle equipped with a computer wheel pressure information analysis system and two traction locomotives.

In addition to the stand, rolls are the key components of rolling steel plates, and four-high rolling mills need to be installed with two backup rolls and two work rolls.Since the back-up roll of a 5-meter rolling mill needs to be poured with a 450-ton vacuum steel ingot, it is forged by a 2000-ton hydraulic press, and then precision-machined by an ultra-heavy lathe. The manufacturing is extremely difficult. Only a few companies in Germany and Japan can produce it. , The cost of a single root is as high as more than [-] million yuan.

Therefore, the country must invest in corresponding technological transformation, and finally the two work rolls have been localized. In this way, Xia Guo still has some technical deficiencies, so he had to find a way to import two rolling mill backup rolls with a pressure of more than 400 tons from Germany. .

Finally, four years ago, Xiaguo completed the assembly of the 5500mm extra-wide and thick plate rolling mill, and spent countless money back and forth. This is industrial upgrading, and the research on each key equipment often costs billions, or even tens of billions. .

If there is no strong domestic demand, it is often difficult for the rulers to make up their minds to study such equipment, because any investment needs to be returned. The 5500mm extra-wide and thick plate rolling mill can produce more than 200 million tons of high-standard thick steel plates a year.

However, the more than 200 million tons of thick plates cannot meet Xia Guo's needs. Other large domestic steel companies will also install such giant rolling mills one after another. Therefore, after Xia Guo's research is successful, it will not take a few years to recover the investment.But there is such a huge demand in small countries, so such equipment is the real standard equipment for big countries.

However, it is impossible to require private enterprises to make such huge equipment, they cannot bear such a huge investment, nor can they bear the risks brought by huge investment.If they really have this money, they can put it in areas where the money comes in faster. Why make such an investment, it is obviously not worthwhile.

The successful advance research and development of the 5500mm ultra-wide and heavy plate rolling mill did not delay the research of the aircraft carrier, so at this moment, the aircraft carrier is stepping up repairs. According to the plan, next year, no later than the year after the next year, the repair of this aircraft carrier will be completed.

But at this time, the problem also came, the aircraft carrier came out, where is the carrier-based aircraft used by the aircraft carrier?It can't be that the aircraft carrier has come out, and the carrier-based aircraft has not yet come out, but fortunately, the AVIC aircraft did not hold back this time.At this time, the carrier-based aircraft required by the aircraft carrier is being developed, and the first fighter jet for the first flight is being assembled, and the first flight is planned for the beginning of next year.

This time, although AVIC Northeast was a bit slower, Sun Zujie was still acceptable.After all, the research and development of carrier-based aircraft is indeed very difficult, and Xia Guo has no experience in researching carrier-based aircraft before.

Of course, there are various reasons why AVIC Northeast performed well.Seeing that the construction of the aircraft carrier is about to be completed, but the plane has not yet come out, the pressure from all sides is driving AVIC Northeast to go crazy;

What makes them feel even more pressure is that Xia Guo's first fourth-generation carrier-based aircraft for the navy is also under development, and it starts almost at the same time as the J-15. If the J-15 slows down, it is possible for the Haisi to replace the J-15.

After entering the center, Sun Zujie made a major decision, that is, AVIC and Huafei will develop carrier-based aircraft at the same time. AVIC is researching the J-15. At the same time, Hongdu will start the pre-research of the fourth-generation naval carrier-based aircraft.

The J-15 has a prototype from Ukraine for reference, but the top ten also has advantages, that is, at the beginning of the development of the top seven, Sun Zujie asked Hongdu to use the Bumblebee as the prototype. Pre-research work.

It was said at the time that it was not used now, but it did not mean that it would not be used in the future. In addition, through the research and development of Qiangqi, Xia Guo had a good relationship with the local tyrants in the Middle East, and even had the opportunity to take a look at the Bumblebee purchased by Kuwait, so They also have a certain understanding of carrier-based aircraft.

Of course, the Qiangqi engine uses the turbofan 404, which is a grade behind the F[-] used by the Hornet. It cannot meet the needs of the fourth-generation naval fighter at all. Huaxia Power must develop a corresponding new type of push.

Same as in history, in order to replace a large number of domestic J-7s, Pakistan finally asked Chengfei to help research a third-generation light fighter Xiaolong, and the medium-sized engine that Chengfei finally chose was the Russian-made RD93.

Since the Russian-made RD93 mid-range can be introduced, it is completely possible to follow the old method of the J-20, first use this mid-range as the basis, and develop the top ten, and then replace it after the domestic mid-range is developed.

Therefore, after the development of a new generation of domestically-produced China, it can also be used in Xiaolong in the future, so that it will not be blocked by Lao Maozi. With the existence of two fighter jets, there will be no installation problem.

The pre-research of Qiang Ten started nine years ago. At the beginning, it was only an internal plan of Huatou. Huatou was responsible for the pre-research costs.

It was officially included in the national plan four years ago. The reason is that the country's military expenditure has continued to increase over the years, which can already support the official development of Qiang Ten, and at this time Qiang Ten has already achieved certain results.

Of course, Huafei's habitual preemption has caused strong dissatisfaction in AVIC. You have taken all the research and development of the navy and air force.

Sun Zujie already had a solution to this. He asked AVIC to join the research and development of Qiang Ten. Qiang Ten is a multi-functional fighter jet, corresponding to the F35B used by the U.S. Navy, and AVIC will develop a F35A for the Air Force in the future. 20 high and low collocation, as for the code name, we will talk about it after it is developed.

The two fighters use a similar stealth shape, which can save a lot of research and development costs, and the United States does this.Of course, now we are still honestly working on the top ten, and when the country really needs it, we will develop a multi-functional attack aircraft for the air force.

In desperation, AVIC had no choice but to hold its nose and admit it. Anyway, they were also involved in the development of a fourth-generation fighter jet.

But in this way, the J-15 was pushed to a dead end. If the action was slower and Qiang Shi was smoother, it would be possible for the center to dismount the J-15 directly, so AVIC Northeast had to work hard.

This is also the reason why Sun Zujie promotes the research and development of Qiang Ten. He must constantly put pressure on AVIC. With pressure, there will be progress and internal problems can be reformed. Similarly, if AVIC progresses, Huafei will also make progress.

So in Bincheng, Sun Zujie not only saw the aircraft carrier under intense construction, but also visited the technicians of AVIC Dongbei and Huafei Hongdu, and expressed his condolences.In the afternoon, Sun Zujie went to the Naval Naval Academy to visit and investigate, and then held a symposium with teachers and students of the Naval Academy.

Regarding the navy, Sun Zujie is relatively at ease. The reason is that the navy in the 90s was the main force in business smuggling, which led to the messy performance of the navy at the beginning of the century.

After the 361 submarine incident, the center strengthened the management of the navy. After several years of rectification, the navy has improved a lot.After Marshal Wu took office, the development of the navy has entered the fast lane, so both the center and Sun Zujie are relatively reassuring about the navy.

But Guangguang is not bad. In the next few years, the navy will face more and more pressure, such as the Yellow Sea and Northern Dynasties, the direction of Waguo Bay in the East China Sea, countries in the South China Sea, and overseas rescue and escort missions. So when Sun Zujie spoke These four points are specifically mentioned.

Sun Zujie believes that after this round of financial crisis, the gap in national power between the Xia Kingdom and the U.S. Empire has significantly narrowed. In order to suppress Xia, the U.S. Emperor is likely to shift its attention to the Far East and continue to increase its troops stationed in the Far East .

And once the U.S. imperialists come over, besides the naked threat of force, they will definitely continue to do all kinds of bad things. According to the U.S. imperialists, they want to use their soft power.

Sun Zujie believes that the North Korea issue, the Diaoyu Islands issue, the South China Sea islands issue, and the Gulf issue may take turns to play, and the navy will face the enormous pressure from the world's largest naval power. challenges from the empire and surrounding countries and regions.

"Comrades, please remember that it is all preparations, all preparations! Some comrades may think that my judgment on the situation is too pessimistic, but we must clearly understand that we are already the world's second largest economy, and we have developed to the United States. The upper limit that God can accept.

Unless we stagnate and castrate ourselves like Japan, the US imperialists will definitely suppress us in order to maintain world hegemony.The means of suppressing us include trade and finance, but the most effective means of suppressing a country is always war.

Comrades, you must remember that American imperialism will take risks, and dare to take risks.Since the founding of the country, this country has been fighting continuously for more than 200 years. Even nine years ago, they bombed our embassy without hesitation.

Don't say that big countries dare not fight, they already have excuses.When the contradictions intensified, it was not difficult for them to use the mistaken attack as an excuse to destroy several of our warships.If they think such a risk is worth it, they will do it.

And the means to prevent the US imperialists from taking military risks is that we must quickly build a powerful and modern people's navy that can effectively deter them, at least on the Pacific side.

Our national strength has become stronger, and military expenditures are increasing at a rate of 10% every year. We already have the financial resources to build a powerful fleet to defend our coastal defense and our maritime interests.

But as the saying goes, for a century-old navy, the most difficult thing to build a powerful navy is not money or warships, but talents, qualified naval talents.

Students of the Naval Academy, you are blessed. You are at a once-in-a-lifetime opportunity. You have encountered the rising period of the country. You don’t have to use backward sampan gunboats to protect the motherland’s waters like your predecessors.

In the future, you will be riding on an aircraft carrier, a guided missile destroyer of several thousand tons or even ten thousand tons, and an advanced nuclear submarine. These will be the world's most advanced and even leading technical equipment.

Classmates, your conditions are better than any period in history, you must cherish them, you must work hard, learn knowledge and skills well, and give full play to our advanced equipment.

Only if you are outstanding, our party, our country, and our people will be truly protected. Students, come on! "

After delivering an impassioned speech, Sun Zujie then rushed to Fengtian, inspected the organs of the Fengtian Military Region, and received generals above the division level of the Fengtian Military Region.

In front of these generals, Sun Zujie spoke for a long time about the style of the Privy Council, put forward a series of rectification requirements, and finally took a group photo with them.

When all this is done, Sun Zujie's inspection on the third day will be in the field of people's livelihood.Sun Zujie listened to the work report of Liaodong Provincial Party Committee Secretary and Governor Zhong on dealing with the financial crisis.

After the report, Sun Zujie told the senior cadres of Liaodong very seriously, "Comrades, Liaodong's economic recovery and development in the past few years have been quite outstanding, and good progress has been made on the road of industrial upgrading.

But it is undeniable that your achievements in the past five years are, in the final analysis, the recovery and development of domestic and foreign markets after my country's entry into the WTO; in the final analysis, it is the economic growth brought about by the country's huge investment in the Northeast.

The fundamentals of Liaodong's economy have not changed much. The problem that Liaodong's economy focuses on heavy chemical products and equipment manufacturing is still very prominent.
