However, in the current world, if Ming Dynasty starts to develop electroslag remelting technology from now on, directly starts industrial production attempts, and accumulates production experience, it should take about ten years to use electroslag remelting for large-caliber naval guns.

Molten steel.

Even if large-caliber naval guns will be eliminated sooner or later, tanks and army artillery are still in long-term demand.

At the same time, electroslag remelted steel can not only be used in artillery, but also has a wide range of applications in industrial production.

As long as electroslag remelting technology can be developed, it will be a huge improvement to the industrial level of Ming Dynasty.

Therefore, this technology is undoubtedly a key issue to be researched.

Then there is the body tube self-tightening technology.

Body tube self-tightening technology is a solution of body tube tightening technology.

The history of barrel fastening is very long. The round hoops on the outside of bronze cannons in the classical era can be regarded as the application of barrel fastening technology in a broad sense.

In the era of dreadnoughts, there were two main methods for fastening the barrel of naval guns: "wire wrapping" and "layering".

Wire wrapping, as the name suggests, is to make steel wire with a square cross-section and wrap it in several layers around the outside of the barrel to increase strength.

Layering means to make the barrel into multiple layers and nest them layer by layer to increase the strength of the barrel.

Large-caliber naval guns throughout the dreadnought era basically used these two processes to tighten and strengthen the barrel.

The barrel of modern artillery is self-tightening, which is actually a "single barrel wall self-tightening".

The barrel is no longer a complicated multi-layer nesting, and there is no need to carefully wrap the steel wire.

It can be said that it is quite simple and crude to directly use hydraulic equipment to pressurize the gun barrel outward to make the inner layer of the gun barrel denser, forming an effect similar to the nesting of multiple layers of gun barrels.

Compared with the complicated traditional production process, the single-meat self-tightening method can significantly reduce the weight of the gun barrel while increasing the firmness and durability of the gun barrel.

However, even if Zhu Jingyuan's understanding of metallurgical technology is limited to an extremely superficial understanding of related technologies as a military fan, he can imagine that the hydraulic tube self-tightening technology will definitely have very high requirements for sealing and pressurizing equipment.

high.

Because in most cases, the so-called simple and crude solutions are usually low-end luxury applications of superb basic capabilities.

Just like Li Da Bian Fei in the aviation field...

Therefore, although Zhu Jingyuan wrote down the idea of ​​electroslag remelting and hydraulic tube self-tightening processes and his understanding of the two processes in as much detail as possible, he also made a clear distinction between the importance of the two.

The Ministry of Industry and the Royal Consortium are required to prioritize the development of electroslag remelting technology.

As for the barrel fastening solution, if hydraulic self-tightening is difficult to achieve in the short term, we will continue to optimize the existing self-tightening technology.

Based on my experience in my previous life, there is obviously potential here that can be tapped.

The American sixteen-inch (406 mm) naval gun increased the shell size to 1,227 kilograms.

For the 420mm naval gun designed by the Ming Dynasty, if the shells were enlarged proportionally, they should be increased to 1360 kilograms.
