"This is, the automatic correction of metal melting?"

Ronan looked at a silvery-white steel ingot half a meter long with the thickness of his forearm in his hand, and his eyes lit up with joy.

He threw the steel ingot into the alchemy furnace again, and took out the forged knight's sword.

Then he picked up a knight's sword of the same specification made of steel from this era, raised it high, and swung it at it vigorously.

With a bang, the crisp sound of metal clashing, the blade of one knight's sword curled up, while the other was intact.

"Sure enough, this strength of steel far exceeds the metallurgical technology of this era."

The use of alchemy furnaces includes not only metal cutting, but also metal smelting and heat treatment.

This means that Ronan has the ability to produce steel with properties far beyond his time.

This not only means that he is more durable and durable, but also that he can achieve technology that is ahead of his time with the support of materials.

Although Ronan didn't know how to make precision parts like modern machine tools, he still knew a little about the steam engine, an old antique with a not too complicated structure.

Steam power has been involved in this era, but it is still in its most primitive stage.

It is to connect two metal pipes with a hollow metal ball, and steam is passed into it to make the metal ball rotate and generate power.

With its extremely low thermal efficiency and power output, it has no other use than to pull up curtains in theaters.

The reason why Ronan didn't think about the relevant equipment before was because the quality of steel in this era was not up to par.

Its own alchemy furnace is so big, and the most critical cylinder piston must be formed by the alchemy furnace in order to ensure tightness and reliability.

If you divide the parts into different parts and rely on a blacksmith to assemble and weld them, the connection points will be blown up 100% under steam pressure.

But here comes the new problem, the smaller the volume, the higher the pressure needed to get the power.

In order to ensure the power output of the cylinders, it was impossible for Ronan to use the original version of the atmospheric steam engine.

That is, let the steam enter the cylinder, and then close the steam valve, let the cold water enter the cylinder, the steam in the cylinder condenses when it is condensed, forming a vacuum, and the cylinder is pushed by atmospheric pressure.

Due to the size constraints, he needed to use a reciprocating steam engine that had been converted from a single cylinder into a two-way cylinder, using high-pressure steam as the driving force.

This meant that he needed cylinders that could withstand this pressure, as well as a high-pressure boiler to match.

Technical manufacturing is not the problem, the problem is in the material.

Even if it is formed in one piece, under the long-term reciprocating motion, the fragile steel may still explode, and there are serious safety hazards.

But now it's different, Ronan looks at the brand new steel in his hand.

When he tried to use the alchemy furnace to remove sulfur and phosphorus from steel, and added mineral soil to add manganese, silicon and other elements, he got a new type of steel.

Alchemy furnaces have a special correction mechanism.

When a certain element is removed or added to the steel, it will automatically change the metal structure in the steel accordingly, so as to get the desired effect.

Sulfur and phosphorus removal can improve the plasticity and toughness of steel, and the addition of manganese can produce a stable austenite structure, which greatly improves the strength and wear resistance.

In the end, he got the special steel that Ronan now has in his hands.

"It is really luxurious to take the steel of more than a thousand years to build a steam engine more than a hundred years later."

Ronan threw in a piece of gold to power it, and then put a large amount of the special steel that had already been produced into the furnace.

He was also thrown in with the blueprints he had drawn for the steam engine.

The scale is set by himself according to the spacing after folding the paper several times.

Since the main body parts did not need to be assembled, Ronan only had to pay attention to the tightness and movement of the pistons in the cylinder.

As for the size of the other parts, there is no precision requirement, after all, there is no need to consider matching.

The golden flame flickered, and the steel in the furnace vanished.

Instead, a cylindrical high-pressure boiler is connected to a cylinder, with a length and width of about one meter and a half.

Ronan called for the crows, strengthened it and helped drag it out of the basement, then assembled the remaining linkage and flywheel outside the castle.

With the steam engine, it means that the efficiency of coal mining and transportation can be greatly improved, and he can make up for the shortage of manpower.

Ronan called Ed and Old Motou and began to explain to them about the steam engine.

"My lord, do you mean it's a cargo wheel powered by a steam ball?"

After listening to his introduction, Lao Motou's expression was complicated, and he didn't know whether to say something in his heart.

He had seen something similar when he was president of the Insel Waterway Chamber in the Rhineland.

It was brought by an Imperial Scholar from Bachelor's Castle and wearing brown and black academy robes.

He approached himself and claimed to be able to lift the ship's cargo on a powered wheel and unload it quickly.

Even the lord at the time, the current Viscount Claude, was alarmed and ran to the docks with interest to watch him activate the huge power wheels.

However, the results were disappointing.

While loading and unloading a box of ore, a black metal bucket attached to the wheels exploded, killing the two workers who were adding firewood to the side.

The scattered debris injured many civilians in the vicinity, and the nobles were frightened.

In the end, the Imperial Bachelor fled in disgrace under the scolding and taunting of the dock workers, and disappeared.

And that metal device was also ordered to be completely destroyed under the cold gaze of Viscount Claude.

Compared to the previous device, the one he had seen was much smaller, and the power of the explosion was probably much smaller.

Old Mo Tou thought of this and relaxed.

Ronan saw the worry in Lao Motou's eyes, and knew that in this era, if it was related to fire and pressurized equipment, there was basically no safety.

He decided to prove it with real actions.

It's just that after Lao Mo saw his movements, he hurriedly pulled him away and took over his work.

Under Ronan's command, he added water and coal to the boiler and started it, and then Old Mo hurriedly pulled Ronan and Ed away from the equipment.

After ten minutes, the water inside the boiler begins to boil, and the pressure gradually increases.

After a while, when Ronan saw that it was almost over, he wanted to step forward and open the valve, but was hugged by the frightened old Motou.

It was the first time that Ronan had seen a panicked look in the old man's eyes.

I don't know what this has been through, so there is such a big psychological shadow.

"Okay, can't I get closer? Ed, go and tighten that handle to the maximum. Ronan, unable to move, had no choice but to let Ed come forward.

Ed, who was confused by Old Motou's reaction, opened the valve and trotted back to the two of them.

The steam enters the cylinder, enters the spool valve chamber through the main steam valve and the throttle valve, and enters the two sides of the cylinder alternately under the control of the spool valve, and begins to drive the piston to move back and forth.

Thanks to the excellent workmanship, the shaking and roaring of the machine is not too loud, but the flywheel has already begun to spin rapidly under the action of the connecting rod.

"Remember to add coal and water on time, and let it turn for a few hours to test stability."

Ronan instructed the two who were standing stupidly in place, turning to leave.

At present, he does not need to worry about the leakage of technology, this thing is not a product of this era, the key is not the technical structure, but the material.
