The next thing is the visit time, which is still brought by the chief engineer, and the factory director did not follow, Li Zhao is an acquaintance, and he mainly looks at technical things, so he did not follow. Master Zhang's words are mainly to see novelties, and he doesn't understand specific things, and following Chief Engineer Li Zhaohe, what he sees must be the latest research results.

When he came here, the first thing Li Zhao had to see was of course the processing of the hydraulic press, and since the start of production, Li Zhao has not come to see it in person. When I walked to the workshop, I saw that a column was now being processed in the workshop.

At this time, the chief engineer of the military factory said: "The processing of the hydraulic press is too difficult, and you have already reduced this column, but the processing difficulty is still very large, and this is still the case where we have experience in Shanghai." ”

"Fortunately, you came up with new knives in front of you and provided us with a batch, otherwise we would have had more headaches. Most of the big guys of the hydraulic press are made of alloy steel, and the strength of this column is already higher than the strength of the tools we used in the past. ”

Li Zhao asked at this time, "How is the overall progress?" I haven't asked about this recently, and I haven't seen you look for me, so I don't know anything about it. "Li Zhao is also busy, so he doesn't care about processing.

At this time, the chief engineer replied: "The progress is good, after all, our processing difficulty is much smaller than that in Shanghai, and it is hundreds of tons lighter, but with the current progress, it is estimated that it will take about three months to complete all the components." Although we have other people's processing experience, we are also manufacturing for the first time. ”

After taking a look, Li Zhao understood the progress and continued to visit the assembly workshop. Actually, there's nothing to see here. There are only empty factories here, and a lot of insulation treatment has been done, and of course there are many areas, after all, it is impossible to cool all areas, which would be too wasteful. There are also areas dedicated to oil baths, and the assembly method of thermal expansion and contraction is used, and of course it is not just cooling.

There are also some parts that need to be heated during installation, and for such parts, oil baths are generally used. It cannot be heated directly on the fire, which is likely to scrap the parts directly, and the oil bath is the best choice. The temperature can reach two or three hundred degrees, and the heating is relatively uniform, which will not lead to local overheating annealing.

Li Zhao also took a look at these, there was no need to delve into the situation here, at this time Li Zhao said: "You are estimated to be able to produce ice cream on a large scale next year, the area here is really not small, the accessories that need to be cooled only need to be made on the shelf, and it is good to place them directly for a period of time, and your space is too big." ”

At this time, the chief engineer said: "I had this plan, and it can also be used as an employee benefit in the future." It's not easy here, and after solving the compressor problem, we also remember what you said earlier, and the temperature may be lower in the future. We planned these areas and divided them into three grades. ”

"These divisions, the coldest area right now, are estimated to eventually reach minus 60 degrees. The last time we tested, it was in the coldest area where four ice machines were arranged. At that time, when the test was carried out, four of the six ice machines were opened, and the temperature could drop to minus 40 degrees, and the temperature was still slowly dropping at that time, so we turned it off after seeing that the effect was good, and there should be no problem with minus 60 degrees. ”

After hearing this, Li Zhao also sighed that the military factory has a lot of money, but there are more than a dozen ice machines installed here, you must know that the ice machines used in each of these areas are tens of kilowatts of power, and when they are opened, they are all electric tigers. It is estimated that they may lose money in the end by making ice cream, but as a benefit, it is still quite good.

In the end, the two of them first walked to the production workshop, and then the chief engineer introduced: "We have now trial-produced 125 mm and 155 mm guns, and there are still many problems to be solved." Now the biggest difficulty is in the self-tightening of the body, at present we have tried many methods, the effect can not reach the ideal state, at present can only say that there is an effect, but the use is not big enough. ”

Li Zhao said at this time: "This is also normal, after all, we have just started researching, and if we master it all at once, then military production will be too simple." It will not be said that the current situation has arisen, and now there are not many countries in the world that can mass-produce qualified bullets, let alone large-caliber artillery. ”

This is indeed the status quo and the situation in the future, you must know that in the future, it is said that the white elephant, which is said to be the third power in the universe, will not have the ability to make bullets. At this time, Li Zhao continued to ask: "Have the two calibers of artillery been fired live now, and what is the effect?" ”

As soon as Li Zhao finished saying this, Master Zhang, who had not spoken, spoke: "Yes, did you shoot live ammunition?" Ever since I heard Li Zhao mention this, I especially wanted to see the effect of live ammunition, which was 155 mm, and I had never used such a large-caliber gun. ”

At this time, the chief engineer said: "Yes, of course there is, where is there any better way to test the performance of artillery than to fire a few shots directly?" After we tested it, we organized a few shots at the first time, how to say the effect, it is unsatisfactory, and now there are still a few problems that we have not completely solved. ”

Saying that, he took the two of them to the test site by car, and came to the test site, where the artillery was now being inspected, and Li Zhao and Division Commander Zhang both stepped forward to take a look, and there were really not many opportunities to see the artillery at close range.

At this time, the chief engineer of the military factory said: "Judging from the results of the test firing, the power is really good, the effective killing radius can reach more than 50 meters, the specific lethality is still being tested, and the shrapnel still has lethality at a distance of two or three hundred meters." There are many advantages, but again, there are many problems, and we have several problems that need to be solved at the moment. ”

"One is that the recoil is too large, and the current artillery carriage can not complete the buffer of the recoil well, and it is necessary to re-aim once you shoot, otherwise there is no way to guarantee the landing point of the shell, which also seriously slows down the firing speed. We did tests, and without retargeting, the shells could have fallen several kilometers away. ”

"The second problem is that it is so difficult to transport, and there are so few vehicles that can tow this gun now. We have already increased the weight of this gun to more than a dozen tons, and we are constantly experimenting with new gun mounts, and today is the latest design of the gun mount, which has further increased the recoil length, and now it has reached one meter. ”

This is indeed a problem, there are really not many vehicles that can become the towing power of this artillery, and now the tractor can be completed, even the truck is not very good, Li Zhao said at this time: "The current situation is not as good as designing a self-propelled gun, and there are really not many vehicles that can tow this artillery now." ”

At this time, the chief engineer said; "There are such considerations, but there are also many problems, that is, the lack of a good engine, if you want to pull this big guy, the power required is very large. You can try the engine you got today, we don't have any experience building this thing, I still need to ask the professionals. ”

Li Zhao nodded and said: "If you engage in self-propelled artillery, I have some suggestions, we can solve the problem of existence or absence in advance, as long as it is guaranteed to be used normally, the shooting accuracy is relatively high, and the failure rate is not high, then it can be successfully listed." The launch speed can be slightly slower, for example, let's set a rate of fire of two rounds a minute, not fast, but a stable, and then we will slowly improve. ”

Li Zhao's suggestion is very pertinent, it is more important to say that it is more important to use it without taking out one first, as long as it can meet the points that Li Zhao said, basically this artillery can be regarded as a successful artillery. What better artillery in this day and age could be? Now that there is a talent to say, slowly solving the shortcomings is not.

Li Zhao thought for a moment and then said: "If we use the engine I got today, we can give the self-propelled gun's weight to about forty-five tons." We are now solving the problem, and we also know that there are many defects, so we must consider the future upgrade and airborne. ”

"For example, we can now design the car body to be larger, and the structure must be strengthened, in this case, the protection will definitely be more stretched, but it doesn't matter, we just need to leave the installation position of the armor. In the future, our power problem is solved, and we can immediately install the corresponding armor. When the time comes, you can immediately become a fifty or even sixty ton guy. ”

"The speed of the vehicle can be a little slower, and it can run forty or fifty kilometers. We don't need to design too high a speed now, and we will design this gun according to the support gun in advance, and when the power reaches it, we can use it as a follower gun. As long as the car is big enough, we can stuff enough stuff into it in the future. In this case, you should be able to complete a self-propelled gun, right? And we also have enough room for upgrading, once a research breakthrough, we can quickly replace the corresponding parts. ”

"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.
