In fact, heavy equipment such as hydraulic presses, large plate rolling machines, and large cold rolling mills are quite simple in structure, and these heavy equipment cannot be as multi-functional as CNC machine tools, because they are too big and bulky, and often can only do some single actions.

But why can't many developed countries develop it in later generations? The main problem is the material, they are the equipment for processing large parts, they must be excellent, to make an analogy, they are like the anvil of the iron shop, simple but very important, and they must be harder than ordinary steel, otherwise it is a hammer and a pit.

Heavy equipment generally uses large hydraulic equipment, its huge power comes from this, although the large hydraulic equipment and hydraulic equipment are only two words apart, but the difficulty is far from the same, like hydraulic pipelines, arms, cylinder liners, the principle is the same, but the requirements for materials are quite harsh, otherwise it can not be forced, and it will be used to pull the thin pendulum belt, and there must be a special steel with high strength.

Royal Industrial Science and Technology Group did not have special steel before, so in the process of development, the main stressed parts were too unbearable to be developed for a long time, and now there is a usable manganese-vanadium low alloy steel, and these problems are easily solved.

There is also a key problem is the motor as a power source, although in ancient times, but Yang Wenli has extraordinary knowledge, from the beginning is the top strong magnetic brushless motor, the technical level and the 21st century is comparable, are small in size, large torque, but also quite durable.

Coupled with ultra-precision technology, what electromechanical equipment can't be developed? The reason why it has not been developed is because the time is short after all, the time for the development of manganese-vanadium special low-alloy steel is too short, and the volume of those large-scale equipment is quite huge, so it is normal that it has not been developed, rather than a technical problem.

When Yang Wenli walked to the electromechanical R&D team in the industrial zone, the first thing he asked was: "Why hasn't the heavy equipment for shipbuilding been developed yet?" Are there any difficulties? ”

The person in charge of the mechanical and electrical department hurriedly replied to him: "Your Majesty, there are no technical difficulties, the main thing is that there is not enough time, we will step up and develop it in two days." ”

"Oh! Then hurry up, develop it and try it out a little, if there is no problem, we will step up production, and there will be ten units of each equipment, and there are two shipyards, which are waiting to be used!

The technical problems can be solved by the technical department, don't do it alone, do your own best field, and leave it to others if you are not good at it. ”

"Whoa! His Majesty taught that Weichen was taught. Seeing Yang Wenli's dissatisfied tone, the person in charge was so frightened that he broke out in a cold sweat, and he quickly admitted his mistake.

Not to mention, they really made the mistake of working alone, which is the character shortcoming of the Chinese, they don't want to ask for help, and their character is so strong.

It is precisely because of their solo work that they delay time, after all, they are not professional technicians, and when they encounter some problems, they will spend a lot of time to solve them.

Another reason is that the industrial area is too large, and the mechanical and electrical team is far away from other scientific research departments because they have to study heavy equipment.

How far is that? It is more than three kilometers long, and there is no public carriage in the industrial area, so they all rely on two legs to walk, and if there are some minor problems, they are too lazy to trouble others, and they all find their own ways to solve them.

Yang Wenli just knocked it out and stopped delving into it, as long as there are no technical problems, with the help of the technical department, I believe that it will be developed soon, and they are also working hard, he can't be too demanding.

The mechanical and electrical department finally had clear good news, and Yang Wenli returned to the ship design team in a comfortable mood, which is the department where he mainly stays, and he himself is the design director.

As soon as he stepped into the large office hall of the design team, someone came to ask him for advice.

"Your Majesty, according to your exterior design drawings, you indicated that the armor steel plate must be mirror-welded, but you went to ask the technician department, and they didn't know what mirror welding was? Please also ask Your Majesty for advice. ”

He was in charge of the design of the armor process, and at first he was immersed in drawing, because he didn't understand the process in the first place, so he didn't care if it was mirror welding, but today at dinner time, when he discussed this issue with Yang Liren of the technical department, he found that they actually didn't.

This is a big trouble, because Yang Wenli specially pointed out that mirror welding must be used, so as soon as he saw Yang Wenli, he hurriedly asked him for advice.

"Oh! This is an assumption of the widow, strictly speaking, this is no longer part of the scope of welding, which requires a very precise process, which is exactly what suits us.

Even later generations of shipbuilding did not use this advanced technology, generally used ordinary welding, you don't look at us and the later generations are hundreds of years apart, just think that we are comprehensively backward, in fact, the level of technology, mainly determined by people, the highest level of later generations is the eighth level of technicians, and we have nine level technicians, only from the level of technology, we have to surpass the later generations.

In view of this situation, I decided to use this welding technique, which is the most difficult but most effective. ”

"Your Majesty, what exactly is mirror welding?" Yang Wenli said for a long time, but he didn't say anything, he didn't even say half a word about what mirror welding was, and he was bragging, so the designer in charge of the hull shell armor design asked him again.

In fact, in the microscopic world, atoms oscillate all the time, it is this characteristic that we can cast and forge a whole piece of armor steel, and the oscillation of the atomic level makes them closely connected, otherwise steel is iron atomic gas, and cannot be formed into a whole.

According to this characteristic of the atom, we only need to find the conditions to accelerate the oscillation of the atom, such as high temperature, such as magnetic field excitation, we can connect two pieces of steel of the same thickness, very close to each other, into a whole, as if they were a whole piece of steel.

Its advantage is that there is no weld, it is really a whole, no defects, but it is also very difficult, first of all, before welding, the welding surface must be two mirrors, and then through superb technology, so that the two mirrors coincide, leaving no gap, is a gap that cannot be seen by the naked eye, and then paste resistance wires inside and outside the weld, apply a temperature greater than two hundred degrees, so that the iron atoms accelerate oscillation, so that the two pieces of steel are closely connected, becoming a natural whole.

The principle of the whole welding process is like this, which is very difficult, the first is mirror processing technology, which is the top technology in later generations, but our technical department should be able to do it, the difficulty is how to manufacture in large quantities, which requires the development of an ultra-precision equipment, rather than artificial.

The second biggest problem is the on-site combination, how to make two huge pieces of armor, the weld seam is invisible to the naked eye, which requires both precision equipment and exquisite technicians to do.

It's very difficult, but as long as we do it, the outer armor of the entire ship is a whole, which is not only more beautiful, but also significantly improves the armor strength, which can be said to have many benefits. ”
