Since mankind entered the Iron Age, iron is the foundation of the whole country, the amount of iron, in a certain case, represents the strength of the country, even if it is an agricultural society, it is the same, without enough steel, it is impossible to make all kinds of daily tools, it is impossible to make weapons.

In the era of thermal weapons, the use of steel has risen to the peak, a soldier holding a hot weapon, how much steel needs to be consumed every year, how many times is the cold weapon, and the excellent combat effectiveness of thermal weapons is almost all piled up with steel.

For steel, there is no shortage of Dinghai Navy, from the beginning of the Dinghai steel mill with a daily output of 2 million tons, Dinghai Navy is not short of steel, and then although the steel plant gradually shrinks, but in the steel technology, constantly improving, the actual production capacity is rising.

Niu Dali is such a genius iron and steel scholar, his inspiration, coupled with Zhao Xin's guidance, the steel of the entire Dinghai Navy, savage growth, beyond this era.

The narrowness of the island and the lack of raw materials still limited the expansion of the steel mill in the Dinghai Navy, and the same is true for the Ryukyus in the future, so it is necessary to consider the current situation and collect and develop it.

Now, when this steel center, placed in Anshan, it is different, for Anshan, Niu Dali is not generally satisfied, to put it bluntly, Anshan in line with Niu Dali's expectations of the steel base, as soon as he came to Anshan, he liked it, and began to work crazy for construction, that is, knowing the arrival of Zhao Xin, he relaxed a little and came to greet him.

Zhao Xin came to Anshan, there is some understanding of the nature, no matter what, Niu Dali is second to none in the entire Dinghai Navy's scientific and technological system, he has laid a solid foundation for the Dingjun's steel, and even heavy industry, without him, not to mention that there is no entire Dinghai Navy's series of industrial systems, but the speed will drop a lot.

Naturally, after a brief greeting, he asked about the construction work of Anshan, obviously, mentioning this, Niu Dali's interest was very high, and he began to talk endlessly.

In 50 days, the infrastructure has been basically completed, for some ordinary steel furnace installation work, has also started, everything is going smoothly, it is expected that some ordinary blast furnace, can be put into use within 10 days, and loaded with steel from Anshan, for trial production.

Niu Dali arrived more than 20 days ago, and in addition to coordinating the construction of the entire Anshan Iron and Steel, he mainly focused on some new technologies.

In the construction of the Anshan Iron and Steel Complex, in addition to the follow-up, some special steel projects, some general steel projects, the most important is the 1,100-ton open hearth and 80-ton converter, which is the latest technology in the current naval steel.

Now the entire steel base, the basic 400-ton open-hearth furnace, has basically been installed, which is the foundation of the entire steel base.

At present, after several modifications and adjustments, the technology of 400 tons of open-hearth furnace has been quite perfect, after a series of transformations, the production time of 400 tons of open-hearth furnace is controlled within 6 hours, plus some preparation and cleaning time, can ensure the daily output of 1200 tons.

Don't underestimate this number, if it is uninterrupted 24 hours a day, and produces 365 days a year, with an annual output of more than 400,000 tons, this alone can complete the production capacity of the Northern Song Dynasty many times before.

Such open-hearth furnaces, in this steel base, a total of 8, the basic production capacity of more than 4 million tons, is relatively dense, but compared with the original one of the former Dinghai Steel Plant, the overall volume is much smaller, and the practical personnel are also much less.

These are relatively mature technologies, the earliest application to the Dinghai, and later in the Ryukyus also built, is a more conventional project, now in the Dinghai, in addition to Niu Dali, at least more than 20 people, have experience in construction and supervision, these Niu Dali just look at the progress on it, and do not have to personally stare at it.

The best technology of 1100 tons open-hearth furnace, which is the latest technology in the Dinghai Naval Laboratory, not only has the entire volume expanded by 3 times, but also the production efficiency has been improved a lot.

Steelmaking, the volume is quite important, the volume is increased by 3 times, the technical indicators required, as well as the technical content, are also quite high, the same furnace, has carried out several reforms, the efficiency of production compared to the 400 tons of a little improvement, can reach a day close to 4 furnaces, that also means, such a steelmaking blast furnace, one, can be produced in one day, 4400 tons, the annual output of more than 1.6 million tons.

Of course, the 1100-ton blast furnace, because the technology is not mature, it is impossible to apply it at such a full capacity in the future, and if there is a problem, it will be a nightmare for the entire Anshan Iron and Steel Group.

In the same way, a larger volume brings a greater output, and it will also make some large castings possible, although it is said that the Dinghai Navy now, without this demand, it is still necessary to take precautions.

In the future, with the emergence of various stamping machines, especially the 10,000-ton forging press, the molten steel will be injected into the grinding tool at one time, and the next molding will be formed in the work of the forging press, which will have a huge improvement in the overall performance, and the most important thing is the cost advantage.

Niu Dali stared at the two, one is big, the other is small, the small is also the leading technology, this is under the comprehensive guidance of Zhao Xin, under the efforts of Niu Dali, after countless failures, to complete the latest technology.

So far, the largest converter manufactured is an 80-ton converter, and in Angang, the 80-ton converter installed, it sounds like the total amount of converter is relatively small, but the daily output is quite high.

The average time of running in the furnace is no more than 45 minutes, so that the speed of reproduction can be controlled within 2 hours with preparation and cleaning, which means that once fully put into production, the number of daily output has reached 1000 tons, almost second only to 400 tons of open-hearth furnaces, but the volume and use of personnel have been reduced a lot, which is the real technological leadership, the efficiency of 12 furnaces a day is much higher than that of open-hearth furnaces.

At present, in the plan, there are 8 open-hearth furnaces, 2 open-hearth furnaces of 1100 tons, and a little more converters of 80 tons, reaching 15, which is the most among all steelmaking furnaces.

In terms of 8 million tons, this output is equivalent to the total number of major steel mills in Dinghai, which is quite huge, and the same technology is leading.

The history of steel in the Dinghai Navy, from the establishment of the Dinghai, and even before, can be traced back to the Daimyo Steelworks, and then gradually climbed the technology, in terms of technology, has been quite outstanding, to put it bluntly, not less than the level of the end of the 20th century, and some categories are also complete.

Now, in addition to crude steel, there are dozens of different categories of stainless steel, special steel, rebar, etc., and the properties are also different.

To put it bluntly, once this steel plant is completely put into use, it will definitely have a far-reaching impact on the entire Dinghai Navy.

Heavy industry has always been the pillar of the country, although the investment is huge, the construction of a heavy industry system, that is a huge investment, and even the follow-up investment is not a lot, but once the benefits are generated, then the whole benefit is very high, not to mention compared with agriculture, even compared with some profitable light industry, it is not much better.

Niu Dali here, Zhao Xin got a satisfactory answer, under Niu Dali's combing, the development of the entire Anshan base is very good, whether it is the steelmaking base, or the construction of Liaoyang, everything has entered the formal.

Zhao Xin just came to take a look, he is not a professional, professional things, or leave it to professional personnel to do, Niu Dali is professional enough here, and similarly, there are also a large number of people who are helping him, which he is very relieved of.

But then, there are many mines that need to be visited, for example, iron ore mines in Anshan, coal mines, and other mineral deposits that have been developed and put into use.

The machinery of the Dinghai Navy is quite developed, but under the premise of no steam engine, it is only the use of manpower and animal power at present, and it is okay in urban construction or small-scale use of forces, but in the mines, not every place can be arranged, and now, most of the places are still dominated by manpower.

Even in the 21st century, mining is a very dangerous and hard work, not to mention in this era, at present, the miners of the Dinghai Navy are still those stubborn captives, although the Dinghai Navy has taken care of them as much as possible, adding a lot of equipment to them, and at the same time, ensuring that their diet is rich, but the mortality rate is still there, and it is not low.

This is also a helpless thing, you can't let the personnel of the navy do it, fortunately, the mortality rate is controlled at about 3 per 1,000 per year, according to the current situation, in the entire scope of Liao, hundreds of mines of various types, a total of about 210,000 miners are used, and more than 600 people will die every year.

After looking at the situation of the entire mine, the output of various minerals has been piled up, much higher than expected, in the future, after the completion of the Anshan Iron and Steel Base, these minerals will be the first time to support Anshan, and then supply output, become the basis of the entire Dinghai Navy's industry.

In the vicinity of Liaoyang, about 7 days stayed, tested a few mines, and saw Niu Dali, homeopathic, Zhao Xin around Shenyang, Shenyang's unique conditions, is related to the distribution of some surrounding minerals and land, whether it is Fushun, or Anshan, or Liaoyang, which in later generations, are famous cities, now, in the original position, Zhao Xin is just to reproduce them.

These large and small bases, some are a little faster, such as Fushun and Liaoyang, and some are a little slower, such as other directions in Shenyang, but they are all developing rapidly, it is expected that in a maximum of three years, the industrial zones around Shenyang can be formed, and when the time comes, the heavy industry relying on steel, and other industries relying on various machinery, will make the output value of the entire Dinghai Navy rise to a higher level on the original basis.

At the same time, a large number of heavy industry, with the use of the location, for example, the iron and steel industry, before, the demand for the navy was so large, whether it was large-scale housing construction, or the construction of the railway, it has little to do with the navy, the railway network construction speed of the Northern Song Dynasty is relatively fast, but it is only relatively fast, compared with the limit of the navy, the difference is not a little bit, really when the Anshan iron and steel plant is put into operation, a large number of more advanced rails to complete the production, the navy will let them see, how the railway is built, At that time, the entire three northeastern provinces, including Inner and Outer Mongolia, will become a grid-like railway complex, from any city in the northeast, to any place, there will be no traffic problems, in the north in winter, the railway is the best way to travel.

Everything is going well, after 3 years, the control of the entire Liao State can be taken to a higher level, and after that, it will be gradually expanded, even if it is impossible to attack the Northern Song Dynasty, he can also go outward, to the north and south, and even across the ocean, to the other end of the Pacific Ocean, which is not a difficult thing at all.

After almost a month of inspection, around Shenyang, a big circle, the cumulative journey of more than 1,700 kilometers, is considered to be the surrounding construction, have a rough understanding, Zhao Xinhui to Shenyang, this as the future of the naval capital of the city, almost a day, hundreds of thousands of construction troops, here, like worker ants, hard work, in the reinforced concrete building, not all completed, the steel structure of the building, become the main body, original, Shenyang, which was full of low and dilapidated houses, changed, becoming more spacious and taller, and even next to the palace of the old Liao, a building appeared according to Zhao Xin's aesthetics and the pattern of the navy.

This is Zhao Xin's new residence, and it is also the political center for a long time to come, when the time comes, the entire staff team, including the newly established government agencies, will work around it, forming the power center of the future navy.

Zhao Xin happily cut the ribbon for it, although it is a temporary building of steel structure, but it is much better than the old palace, living is much better, at least speaking, all kinds of functionality, relatively complete, but also more complex Zhao Xin's aesthetics.

However, the various staff members who had not waited for it to live in, including Sun Ji and Xue Yu, the middle and high-level officials of the Dinghai Navy gathered together and came to Zhao Xin's front together, and they had only one purpose, to persuade them to advance.

That's right, the Ding Navy has occupied this piece of land that originally belonged to the Liao State, and now there are no obstacles, according to the law, Zhao Xin should ascend the throne as the emperor and rule all the soldiers and civilians in this place in a justifiable manner.
