Chapter 39 Special Steel

"This is the automatic correction of metal smelting?"

Ronan looked at a half-meter-long silver-white steel ingot that was as thick as a forearm in his hand, with joy in his eyes.

He threw the steel ingot into the alchemy furnace again, took it out and cast it into a knight sword.

Then he picked up the knight sword of the same specification made of steel from this era, held it high and swung it down vigorously.

Bang, under the crisp sound of metal collisions, the blade of one knight's sword had a curling opening, while the other was intact.

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

Regarding the use of alchemy furnaces, there are not only metal cutting processes, but also metal smelting and heat treatment processes.

This also means that Ronan has the ability to produce steel with performance far beyond this era.

This not only means stronger and more durable weapons and agricultural tools, but also means that with the support of materials, he can realize technology beyond the times.

Although Ronan didn't know how to manufacture precision parts like modern machine tools, he still knew something about steam engines, which were not too complicated in structure.

This era has already involved steam power, but it is still in the most primitive stage.

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

Extremely low thermal efficiency and power output, it is of no use other than for pulling up curtains in theaters.

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

My own alchemy furnace is only so big, and the most critical cylinder piston must be formed by the alchemy furnace at one time in order to ensure airtightness and reliability.

If it is divided into different parts, rely on blacksmiths to assemble and weld, under steam pressure, 100% of the connection points will be blown up.

But the new problem comes again, the smaller the volume means the higher the pressure required to get the power.

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

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

Under the limitation of volume, he needs to use a reciprocating steam engine that converts the original single-phase cylinder into a two-way cylinder, using high-pressure steam as the driving force.

And this means that he needs a cylinder that can withstand this pressure, as well as a high-pressure boiler for use with it.

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

Even if it is integrally formed, the fragile steel may still explode under long-term reciprocating motion, posing a serious safety hazard.

But now it was different, Ronan looked at the brand new steel in his hand.

When he tried to use the alchemy furnace to desulfurize and dephosphorize steel, and added mineral soil to add manganese, silicon and other elements, he got a brand new steel.

Alchemy Furnace has a special correction mechanism.

It will automatically change the metal structure in the steel when certain elements are removed or added to the steel, so as to obtain the desired effect.

Removing sulfur and phosphorus can improve the plasticity and toughness of steel, and adding manganese can make it produce a stable austenite structure, which greatly improves the strength and wear resistance.

Finally got the special steel in Ronan's hands now.

"It is really a luxury to build a steam engine that is more than 1000 years old with steel that is more than 100 years old."

Ronan threw a piece of gold as an energy drive, and then put a large amount of special steel that had been produced into the furnace.

He also threw in the design of the steam engine he had drawn.

The scale is self-defined by him according to the spacing after folding the paper several times.

Since the main parts do not need to be assembled, Ronan only needs to pay attention to the sealing and movement of the piston in the cylinder.

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

After the golden flame flickered, the steel in the alchemy furnace disappeared.

Instead, a cylindrical high-pressure boiler is connected to the cylinder, with a length and width of about 1.5 meters.

Ronan called the crows, strengthened it and helped drag the equipment out of the basement, and then assembled the remaining linkages and flywheels outside the castle.

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

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

"My lord, do you mean that this is a cargo wheel powered by a steam ball?"

After listening to his introduction, Old Motou had a complicated expression, and he didn't know whether he should say something or not.

He had seen something similar when he was the chairman of the Insel River Channel Chamber of Commerce in Rhineland.

It was brought by an imperial bachelor from Bachelor's Castle, wearing a brown-black academy robe.

He found himself, claiming to be able to use a powered wheel to hoist the ship's cargo and unload it quickly.

Even the lord at the time, the Viscount Claude, was alarmed, and ran to the pier with interest to watch him start the huge power wheel.

However, the result was very disappointing.

When loading and unloading a box of ore, the black metal bucket connected to the wheels exploded, killing the two workers who were adding firewood nearby.

The scattered fragments injured many civilians around, and the nobles were frightened.

In the end, under the scolding and ridicule of the dock workers, the imperial bachelor fled in desperation without a trace.

Under Viscount Claude's cold gaze, that metal device was ordered to be completely destroyed.

Compared with the previous equipment, the one he saw was much smaller, and the power of the explosion was probably much smaller.

Lao Mo relaxed a little at the thought of this.

Ronan saw the worry in Old Mo's eyes, and knew that in this era, basically no one was safe if it was related to fire and pressurized equipment.

He decided to prove it with practical actions.

It's just that when Old Mo saw his movements, he quickly pulled him away and took over his work.

After adding water and coal to the boiler under Ronan's command, it was started, and then Lao Motou hurriedly pulled Ronan and Ed away from the equipment.

After 10 minutes, the water in the boiler began to boil and the pressure gradually increased.

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

This was the first time Ronan saw panic in the old man's eyes.

I don't know what happened to cause such a big psychological shadow.

"Okay, why don't I get closer? Ed, go and turn that handle to the maximum." Ronan, who couldn't move, had to let Ed step forward.

Confused by Old Mo's reaction, Ed opened the valve, then trotted back to the two of them.

The steam enters the cylinder, enters the slide valve chamber through the main steam valve and the throttle valve, and enters into both sides of the cylinder alternately under the control of the slide valve, and starts to drive the piston to move back and forth.

Thanks to the superior craftsmanship, the vibration and roar of the machine are not too loud, but the flywheel has already started to rotate rapidly under the action of the connecting rod.

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

Ronan gave instructions to the two who were standing there stupidly, and turned to leave.

At present, he doesn't 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.
