Hearing this question, the leader of the machinery department explained: "Team leader, this thing is like this, this project is a separate small project, which was reported by Director Yang at the beginning of the month. Comrade Li Zhao's initial plan was to produce three-ton electroslag furnaces, but later due to a series of reasons, the scale was expanded again and again, until the current production capacity reached the scale of 100,000 tons per month, and the original products produced in the plan were squeezed out. ”

At this time, the leaders of the mechanical department also sighed that the plan could not catch up with the changes, and Li Zhao was even more emotional than them when he heard it. At this time, the leader continued: "One of the original plans is to produce cutting tool steel, and now the demand for this aspect is not large, but the effect is great. The original plan was to use a three-ton electroslag furnace to produce one furnace that could be used nationwide for several months, but now it has been replaced by a ten-ton furnace, and one furnace is estimated to be enough for the whole country for several years. ”

"In this case, it was very uneconomical, so they wanted to build a small electroslag furnace, which mainly produced a variety of small amounts of steel. Now that the installation has been completed, it will be tested in the next few days, and when we give an example to the Damao personnel, we can tell them about the situation of the rolling mill. ”

In fact, there is another meaning, that is, there are experts in the rolling mill now, and if you don't give them some things, it may bring a lot of unnecessary trouble. Just like preparing materials for the refinery now, it is easy to be noticed by those who are interested, and it would be best if you could use a small electroslag furnace to divert attention.

After listening to the report of the leader of the mechanical department, the team leader was also in deep thought at this time, the reason is very simple, these materials with a small amount of materials are very likely to have unexpected effects, and I am afraid that these also need to be kept secret. The steel formula provided by Li Zhao has now begun to bloom in full bloom across the country, and many studies that were originally stagnant or unable to break through at all have broken through at once because the material properties have kept up.

Speaking of submarines, there are so many main factors that affect the performance of submarines, one is the mute effect, which we all know what is the use. One is electronic systems such as sonar, and everyone understands the significance of these. Then there is the depth of diving, which can also improve survivability, in addition to the shape design, the biggest problem affecting the depth of diving is the performance of steel.

In addition to these, there is another item that is not easy to notice, and that is underwater displacement and water displacement. We can look at this ratio, such as the typhoon level, the ratio is about 1.9, and the reserve buoyancy has reached an astonishing 22,000 tons. The Borean God class is 1.4, and the reserve buoyancy reaches 7,000 tons. The Ohio class has only 1.12 and a reserve buoyancy of about 2,000 tons, while the Columbia class reaches 1.2 and has a reserve buoyancy of nearly 4,000 tons.

We don't say whether reserve buoyancy is useful or not, but if there is more reserve buoyancy, it means that you can carry more supplies and weapons. In other cases where performance is comparable, it is clear that a submarine with more buoyancy in reserve will have an advantage. Then the place that affects the buoyancy of the reserve the most is obviously the weight of the hull.

And the biggest factor affecting the weight of the hull is undoubtedly the performance of the steel, I use less steel, can have the same effect, then the reserve buoyancy will not come out? Therefore, when the brochure of steel types was issued, many industries, as long as it involves the performance of steel, have taken a big step forward.

The reason why there are so many orders now is because many projects were directly paralyzed due to the supply interruption of Da Mao, but now they have been supplemented and started again. And now that it involves a new steel formula, how can the team leader not pay attention to it, so he asked: "What should I do about the problem of the formula?" This is very likely to leak secrets, we can't make wedding dresses for others, there are still experts in the rolling mill, and it is likely that they will not be able to keep the secret. ”

Li Zhao was also prepared for this question, so he said: "Team leader, you can rest assured that in the short term, the steel produced by this small electroslag furnace produced by the rolling mill will be mainly metals in the civilian field, which is not lacking in Damao." And like the production of knife steel, we can also do it secretly, for example, directly without ordinary employees contact, we can even do it in the name of experiments, after all, these are not in high demand at present. ”

The reason why Li Zhao dares to take it out for production in the rolling mill now is really to prepare for secret production, and he only needs to add alloying elements himself when producing, and the pretense is metal formula research. In normal times, some civilian steel can be produced here, and it is enough to choose some existing steel from Damao.

For many fields, the performance of ordinary steel is sufficient, and there is no need for high-performance steel. Or the example of a bicycle, for ordinary people, it is enough to withstand three or four hundred catties, you have to make a high-performance alloy steel, so that the weight of the bicycle can reach more than one ton, isn't that sick?

In many cases, it is enough to do so, especially in the civilian sector. The electroslag furnace of the rolling mill can completely produce some civil alloys, and ensure that the parts and materials used can be used. For example, bolts, the strength level of bolts is from 3.6 to 12.9, and the bolts in different use environments have different requirements for strength grades.

After listening to Li Zhao's explanation, the team leader also understood that for some things that don't need to be kept secret, putting them in the sun to show others may be the best way to keep them secret. In particular, the current rolling mills, mainly in the civilian field, take them to the military factory to see the production of alloys, and then take them to the military materials factory under construction to see, so that they will not associate the production address with the head of the rolling mill, where there are mostly products in the civilian field.

Thinking of this, the team leader also acquiesced in this matter, it would be good to have a sense of confidentiality, and when such a device was placed in front of Da Mao experts, they would definitely go to see it. At that time, it will be mainly based on civilian materials, and if Da Mao feels that our supply is insufficient, it can also let the equipment of the rolling mill respond to the emergency.

In the afternoon, Li Zhao was sent to the military factory, Li Zhao needed to guide the people of the military factory to complete the production of alloy steel needed by Da Mao, this work was not difficult for Li Zhao, after all, it was a small equipment. Production is not the difficulty, the difficulty is how to create a scene of overtime production.

Seeing the director of the military factory, Li Zhao told him what he said to the team leader today, and finally emphasized: "That is to say, our focus now is on how to create the production that we are working overtime, and you must know that tomorrow the leader will prepare to lead Da Mao's personnel to visit." By the way, how is the construction of your new electroslag furnace plant, I will definitely visit there tomorrow, and you had better be nervous. ”

At this time, the director of the military factory smiled and said: "This is not simple, what we have is experience, and the way we can best embody overtime production is the tactic of crowds. When we originally set up that equipment, it was for testing, and there happened to be no crane there, so we used the crowd tactics to produce, and then urgently installed the crane for the equipment. ”

As he spoke, the director of the military factory laughed, like a fox who stole a chicken.

However, Li Zhao was also straight when he heard it, or they had a way. You see that we received the order yesterday, we have organized the crowd tactics to work overtime to produce today, what a support for Da Mao's behavior, the most important thing is that because the small equipment in the military factory has not been used a few times, you can see that it is new equipment at a glance.

Coupled with the building under construction in the military factory, it is even more revealing, we are looking for ways to expand production capacity, these are all efforts for your needs, such friends are good enough.

However, the equipment here needs to be transformed, and Li Zhao also asked the factory director to arrange someone to bring the design drawings over and see how to transform it himself. Now Director Yang has gone back to arrange the preparation of materials, and the raw materials can be delivered in the evening, and they will be running from night onwards.

The transformation of this equipment is also particular, that is, to look not professional enough, it is best to use some local methods, the drawings will be sent after a while, Li Zhao looked at it, and then began to draw the drawings, as he thought, the renderings of the transformation look so improper, but they are absolutely easy to use.

After drawing the drawing, of course, it is production, and when the chief engineer of the military factory saw the drawings given by Li Zhao, it felt really incredible, because the drawings were too improper. If they hadn't seen the mature product diagram designed by Li Zhao, they would never have believed that it was designed by Li Zhao.

Because this design is too improper, in order to make the internal elements of the alloy evenly distributed enough, Li Zhao used magnetic stirring, and here it was completely changed to an artificial mode, using magnets instead of electromagnetic stirring, which looks like a temporary installation, too improper, and completely funny.

But Li Zhao wanted this effect, and soon the equipment began to be transformed according to the drawings.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
