Bang!

Bang!

……

The explosion of one after another sounded.

The 5 scarecrows are five meters, 7 meters and ten meters from the explosion point.

There are two scarecrows of 7 meters and ten meters each, one of which is armored.

After the 5 test explosions, the scarecrows of five meters and 7 meters were obviously damaged, and they were basically in an inadequate shape.

However, when the distance exceeds ten meters, the formidable power generated by the explosion will obviously decrease, and the scarecrows in a circle will not at all have any obvious damage except for being obliquely inserted into the ground by the waves.

As for the two test points covered with armor, according to Arthur’s instructions, iron beads were added to the explosive bag.

At a distance of 7 meters, the iron beads can basically penetrate the plate armor, but cannot penetrate the chain mail behind the plate armor, and at ten meters, the penetration of the plate armor is already the limit of iron beads.

Arthur knew that his explosives were counterfeit goods, so he wanted to add iron beads to increase the lethality, and this lethality was mainly used to deal with demonic beast.

The results of the test explosion encouraged the Knights. Arthur stood aside and looked at the pit that was blown out of the ground. Although he was disappointed in his heart, he could only accept it temporarily.

He did not think about making explosives with stronger formidable power, but neither nitroglycerin explosives nor 3 nitrotoluene explosives (tnt) can be produced by the current Upper River Collar.

To make nitroglycerin explosives, you first need to prepare nitric acid and glycerin.

To prepare sufficient concentration of nitric acid, in addition to the existing thenardite, concentrated sulfuric acid is also required.

To prepare concentrated sulfuric acid, a large amount of sulfur minerals such as sulfur and beryl are needed.

Nitric acid is present, followed by glycerin.

The preparation of glycerin requires the use of fat and caustic soda.

Grease Gold Coin can solve it, the problem is caustic soda.

In the industrial production of caustic soda, Arthur first thought of the “causticizing method”, that is, using a caustic soda solution and lime to perform causticizing reaction to prepare caustic soda solution and caustic soda.

Lime is common, but the problem is that soda ash is used again!

Soda ash, the easiest way is to dry algae plants, burn to ashes and then get it through hot water leaching and purification.

Only in this way, the soda ash produced is not pure and the amount is small.

Arthur already has Glauber’s salt. He plans to calcine the Glauber’s salt and limestone at high temperature, and then after leaching, evaporating, refining… and finally obtaining high-purity heavy soda ash.

This is feasible, but the problem is that there is a need for a furnace that can maintain a high temperature!

……

Therefore, if Arthur wants to produce high-efficiency explosives, he must prepare all the “3 acids and 2 bases” except for hydrochloric acid, and face various problems during this period.

Such as the simplest lack of labor…

In short, this is a task that takes time to complete, and before this, Arthur can only use his own earthy explosives. After all, demonic beast comes every year, and it is better than nothing!

Unlike Arthur’s calmness, after watching the five test explosion mercenaries, each and everyone left a great shock in their hearts.

They never thought that this kind of thunder-like power can actually be made and controlled by humans, and it happens that this person is their Earl, and such power will also be used to resist the demonic beast.

There is nothing more delightful than this!

Looking at the people who patted each other on the shoulders with excitement and joy, just about to dance, Arthur laughed and cursed, “Hey! I said you guys, do you have to be so excited? Each and everyone is like eating honey. .”

Reprimanded by Arthur, the Knights still smiled excitedly, looking at him respectfully while answering for sure.

“Good cruel Knight, now all fools!”

Arthur shook the head pretentiously, and after a sigh, he turned and walked towards Factory No. 3.

Plant No. 3 is a horizontal rectangle, from which the river divides the plant into two. The wooden bracket and the woven straw roof are the main body of the plant. Apart from this, all around only encloses a wind wall less than 2 meters high.

Factory No. 3 can be said to be very simple, but the contents inside are by no means simple.

“grown ups!”

“Earl adults!”

……

As soon as Arthur walked into the factory, the dozen or so workers immediately stopped busy.

By the river, driven by the water conservancy, the water wheel is continuously rotating with a metal cylinder, and in front of the metal cylinder, there is a center fixed, slowly advancing forward, and constantly cutting the inside of the cylinder.

Under the cutter, the metal in the cylinder is cut like an apple, and a wire-like metal wire is boring. Although such a scene is far less surprising and shocking than the previous viewing of the explosion, it is completely comfortable. It requires neither manpower nor animal power. The scene of metal cutting metal is also enough to open the eyes of the accompanying Knights. !

After appreciating it, Arthur asked the worker on the side: “What is the latest accuracy?”

This worker is a young scholar, mainly responsible for observing and recording data.

Hearing Arthur’s question, he immediately replied loudly: “Back to Lord Arthur, the latest accuracy is 3 cm per meter! The cylinder being boring now should be able to reach within 5 cm per meter!”

cylinder? what is this? Knights are puzzled.

Hearing the report from the workers, Arthur was satisfied and nodded, with a gleeful expression leaking out of his face-an error of 5 centimeters per meter. This accuracy should be enough!

As a traveler, in addition to gunpowder, the steam engine is definitely an indispensable invention.

In the eighteenth and eighteenth centuries, it was precisely because Watt improved the steam engine that brought efficient motive power to the world, the first industrial revolution was able to kick off!

The principle of the steam engine, to put it plainly, is the process of burning a boiler to convert the energy of the steam into mechanical work.

However, although the principle is simple, it does not mean that the manufacture of a steam engine is simple. It’s like Arthur knows the chemical reaction formula of 3 acid and 2 base, but limited by conditions, it is impossible to prepare it industrially.

The biggest difficulty in manufacturing a steam engine is the tightness of the cylinder and the piston. This is the key to whether high-pressure steam can be formed and can be converted into mechanical work.

In the era of pure hand forging, wanting a blacksmith to build a cylinder with a smooth inner wall and qualified airtightness is tantamount to a fantasy story and is a fundamentally impossible task.

And at this moment, the machine making machine-the barrel boring machine is needed! It was the machine Arthur was seeing now.

This gun barrel boring machine uses a water wheel to rotate the material cylinder and align it with a fixed tool in the center. Due to the relative movement between the tool and the material, the material is bored with a highly precise cylindrical hole, which satisfies the manufacture of various compact machines including cylinders.

After looking at the wire that was being cut out for a while, Arthur asked side Walter: “How many parts need to be manufactured by the boring machine, which will take a few days? In addition, all the parts on the forging factory have been sent ?”

“Sir,” Walter replied quickly, “The parts and components in charge of the forging plant have been completed, and they were all delivered to the next warehouse yesterday evening. As for us, in addition to the current cylinder, there are some parts that need to be finely processed, such as Connecting rods, etc. It is estimated that it will take at least 5 days to assemble the steam engine.”
