Chapter 594 (2/2)

This kind of hydraulic press can barely be used for forging 20 mm thick steel plate - the thickness of steel plate used for destroyer hull of later generations is only about 10 mm, but the steel of today is far from comparable with that of later generations, so Shi Xiong can only use thickened steel plate to improve the strength of the hull.

In addition, the current marine steel plate for the area of demand is not very big, are riveting technology, big deal piece by piece is

With marine steel plate, and the most important keel steel

With keel steel and ship steel plates, the ship can be built. But the problem is, you can't just use these steel to build a hull, can you? You have to have enough power to push the boat, right?

So the high-power steam boiler technology has to break through.

With the technology of high-power steam engine, you have to find a way to turn the power generated by the steam engine into thrust, right? So gearbox technology and propeller technology must be available - Shi Xiong doesn't want to use Ming wheel to push this steel warship, which is too low, and the safety is not high.

If we can't develop propeller propulsion technology, Shi Xiong would rather not build this steel warship.

So the stone bear took out the Archimedes spiral of forging propeller again

It took nearly two years for the research team to produce a barely qualified propeller!

Now that the hull, power, propulsion and weapons are available, what about internal communication?

So Shi Xiong had to instruct the scientific research team to make magnet telephone and communication wire

The outer insulation of the wire alone has kept the research team busy for decades.

When the conditions for building the ship were all met and the steel warship was built on the berth, many problems arose one by one.

Sealing of watertight cabin, sealing and drainage of deck after waves, sealing of watertight door, etc.

I don't know if I don't build it. I only know that the main problems I encountered before are just appetizers. When the ship starts to build, there will be all kinds of problems and problems. It's really out of my mind.

For example, when it comes to the later stage of construction, the sealing of propeller shaft has become a difficult problem.

Although the stone bear knows how to seal the propeller shaft, it is still impossible to make that kind of sealed bearing in this era. So a group of people pondered for a long time, then chose a compromise method, using rubber and vegetable oil lubrication to seal.

This method is not a long-term method. If the propeller shaft runs for a long time, the natural rubber used for sealing will inevitably produce huge wear, and the sealing effect will be greatly reduced.

But there is no way. Under the current situation, we can only choose this method for the time being.

All in all, the difficulties encountered before and during the construction of this ship add up to countless. Otherwise, it would take six years to build the ship.

In order to solve these problems and sufferings, and to successfully build this ship, everyone, including the stone bear, is absolutely searching their brains.

It's no exaggeration to say that the energy used by the stone bear in conquering other tribes in this continent is not as much as that used on this ship.

After paying such a high price, the ship is now successfully launched. It was originally a very happy thing, but now there is a problem of water leakage in the propeller shaft. How can the stone bear not feel anxious?
