"Such a fast speed, raised to an incandescent fire? Nearly [-] degrees Celsius!"

"Awesome, does Xu Shen's stove have any special structure?"

"The combustion temperature of machine-made charcoal is almost the limit at this level. Xu Shen can raise the temperature to this level with a hand-made earthen furnace...unbelievable!"

"If you want to further increase the temperature, you must use professional equipment."

"Yeah, further up, the ordinary fuel and furnace body structure are no longer enough... Fuck! Groove!"

"Lie down... go..."

"On the stove, the color of the flames... Am I seeing it wrong?"

"Is there a problem with the color tone of the display?"

"I'm holding a flagship phone that just came out, and the color adjustment is absolutely top-notch in the industry... so it can only be a problem with the camera?"

"It's not the camera's problem...it's the fire in Xu Shen's stove, it really can have such a high temperature!"

"hiss!"

"..."

The fire is so blue!

In the incandescent flame color, a cyan blue that was so faint that it was almost imperceptible was gradually mixed in!

The cyan blue is still gradually smudged, like a drop of ink soaked in water.

Although the color is extremely light, it is still very recognizable when placed on the white flame body.

Barrage--

"What is perfection..."

"Xu Shen, although this is not a pure cyan flame, but to be able to produce a cyan flame, it is beyond what an ordinary stove can do!"

"With such a large amount of material, it can still reach such a high furnace temperature... I would like to call Xu Shen's smelting technique the strongest!"

"..."

This temperature also surprised Xu Le a little.

[Overload] Is the improvement effect of skills so obvious...

At this moment, even the vitrified inner surface inside the ventilation furnace is melting again.

The wall of the ventilated furnace is as thick as ten centimeters, but its own weight is also very considerable. A large amount of melting inside will inevitably cause a considerable degree of deformation.

Once the amount of deformation exceeds the limit of the structure, the collapse is instantaneous.

This is the so-called durability crash...

Xu Le resolutely activated his skills——

【Characteristic maintenance】!

Durable lock within the duration!

And for the material of the ventilated furnace, as long as the temperature drops and the vitrified inner surface recrystallizes, it is still usable.

As long as the extreme high temperature is not repeated in the future, you can continue to use it as you want, and even maintenance can be avoided.

In other words, as long as you make good use of these two skills, you can heat up for nothing at any time.

How about blood!Xu Le was ecstatic.

The surface is still very calm, the loud, handsome, cool, domineering and almighty character cannot be defeated.

The molten iron began to melt and drip, and the speed at which the furnace core entered a full-scale reaction was far faster than any previous smelting.

The temperature in the ventilation furnace remained stable, Xu Le estimated the time, and silently turned off the [Overload] skill.

Next, it's time to test the quality of the stove and the fuel itself.

The temperature of the furnace dropped slightly, the light blue in the flame faded and turned back to incandescence, but the heat was still overwhelming.

When the vitrification of the inner wall of the ventilation furnace has eased, the duration of [Characteristic Maintenance] has reached the limit, and the skill will be automatically turned off.

The furnace remains stable.

The next step is the normal smelting process, I don't need to worry about it anymore... Xu Le let out a breath slowly.

Barrage in the live broadcast room——

"Xu Shen, terrifying smelting skills!"

"Oh my god, I'm afraid industrial production can't reach such an awesome heating rate, right?"

"The structural details of Xu Shen's stove must be unusual, plus the direction of the sea breeze pouring in, and the stacking of the filling...I have to study it carefully!"

"..."

The super-speed heating directly drives up the smelting speed. It didn't take long for the iron ore in the furnace to react, and the charcoal burning was also coming to an end.

As the temperature drops, the flame color deepens, golden orange, orange yellow, deep red, dark red...

Until the flames ejected from the furnace mouth gradually dwindled, and the air ripples distorted by the heating around the furnace body slowly subsided.

Iron slag and molten iron enter the cooling stage and start to solidify respectively.

Chapter 317

Xu Le clapped his hands vigorously, adding new charcoal to the new stove, and the first show of the first stove was considered to be smelting.

So much iron ore is melted to make molten iron, enough to make four whole gun barrels of Wujiu Kai.

Maybe there will be a surplus... High-quality iron ore is great.

Then it was time for the little blacksmith class. Xu Le pulled over the orangutans who were watching the show and asked them to sit in a row.

"In today's class, let's talk about the process of using models to make sand molds. Do you have any opinions?"

The orangutans with high IQs looked at each other, no objection, no objection, the owner of the boss, whatever he said was right.

Xu Le nodded with satisfaction.

"good.

"The molds we made before were very simple in shape. After hollowing out the sand and solidifying them, we can close the mold and pour molten iron and wait.

"And the things that need to be forged are relatively simple, such as axes, pickaxes, etc., even if they are crooked, it is not a big problem, and it will not affect the use.

"As for trachoma or something on the surface, it doesn't matter."

As he spoke, he picked up an ax made by the orangutans. The surface was pitted, but the blade was polished brightly on the stone.

Although it will not be able to blow hair and break hair, it is still very handy for chopping trees.

"but!"

Xu Le tapped the palm of his hand with the handle of the axe, emphasizing like a serious teacher holding a pointer in class.

When the wood collided with the palm of the hand, there was a low thumping sound. Who knows whether it hurts more to be slapped by him, or to be hit by an axe.

The orangutans were sitting upright one after another. Although they had not been domesticated into battle pets through the [Animal Taming] skill, it did not prevent them from being obedient one by one.

"What we are going to make is a very dangerous gun barrel, so the craftsmanship must be refined, and there must be no sloppy!"

The orangutans nodded one after another. Although they couldn't understand what Xu Le said, the intelligence of the primates told them to follow suit and be done.

Of course Xu Le knew it too.

He was talking a lot of stuff just now, and his main intention was not to give lectures.

It's a different way of explaining, otherwise it would be boring to be alone while demonstrating and babbling.

Let's get straight to the point.

He placed a sand box surrounded by wooden boards on the ground, and the sand box was also put together through an exquisite mortise and tenon structure, which is very convenient to disassemble.

Put the sieved dry fine sand in the sand box, put one layer, compact it, put another layer, and compact it again.

The more solid the sand mold, the better. The orangutans are not as strong as Xu Le, who has the "strength of a mad gorilla", but they can be pressed by their own weight, which is not a problem.

Then put in the model of the thickest gun barrel and start filling sand carefully.

"Be sure to pay attention to the edges and corners when filling the sand. If the porcelain is not compacted, the molten iron will flow turbulently and it will be easily scrapped."

The orangutans in the engineering team looked carefully, and they were the main force in this kind of thing.

Black Star is also watching from the sidelines, and he can come forward to correct when necessary.

After the upper and lower sand molds are all compacted, take out the gun barrel model, and then put in a mandrel of matching size.

The mandrel is used to reserve the internal space for the cast gun barrel, and the structure and center of gravity follow the exquisite design in the skill of [End of Fire].

As long as it is placed according to the holes pressed out of the barrel model, there is no risk of misalignment, which can be said to be extremely considerate.

If it weren't for such a layer of design, Xu Le wouldn't dare to let the orangutans do this kind of thing.

After a sand mold has been remade, when the upper and lower sand boxes are closed, the mandrel is clamped into it, and holes for pouring molten iron are reserved on one side of the sand box.

In addition, the seams are tight and the workmanship is quite excellent.

Basically, it is something that can be done with strength. After all, Xu Le has already completed the most complicated part.

The molds can be reused, but the mandrels can only be rotated one by one.

Under Xu Le's supervision, the orangutans quickly completed the remodeling of the remaining two sizes of gun barrels.

The three sand boxes are placed side by side, which has a serious and neat aesthetic feeling.

At this time, the molten iron that has just been melted has been re-melted, and the froth has been skimmed off, ready to be cast at any time.

Next is what the orangutans have done.

There is a lot of molten iron, but the orangutans have very strong arms. A group of orangutans hold the sand box with one hand, and the other holds the big iron tongs to clamp the clay pot.

Slowly pour molten iron inward from the pouring hole.

The molten iron fills every detail of the mold, wraps the mandrel, and then forces the hot air out of another reserved hole.

Finally, the excess molten iron also overflows from the hole groove, and another important link of sand casting is completed.

Well done... Xu Le nodded with his hands behind his back.

While the orangutans were busy casting gun barrels, Xu Le also started to transform wooden cows and horses.

The current iron shell does not reserve holes for hot weapons, but this is not a problem in front of Xu Da blacksmith.

After removing the casing, Xu Le directly heated these parts until they were red hot, and then began to clang and swing the hammer.

——Casting does not use an anvil, so he and the orangutans happen to be out of the way.

Under his forging, the edges of the iron shell were raised and bent.

A light hammer is used to dig out the seam, and a heavy hammer is used to fix it, and some buckle structures hammered out with scrap iron materials are added, and the rigid suspension frame is completed.

Reinstall the shell back to its original position, and the hanging frame protrudes outward, and the whole Mu Niu Liu Ma seems to have a chilling atmosphere for a moment.

The suspension position of the gun barrel, the loading position of gunpowder, the storage position of the projectile...

The audience in the live broadcast room watched the whole process. These simple but clear structures naturally brought a sense of iron and blood beauty.

In the live broadcast room, since Xu Le built the rock drilling machine, a group of multi-turret believers who have been clamoring for "multiple riveting and steaming" are now clutching their hearts and typing on the keyboard in their mouths——

"Come! Come! Turrets all over the world, unite!"

"Steam power! Rigid suspension!"

"Others, are they still far away!"

"Oh oh oh oh oh!"

The three gun barrels were initially cooled, and the wooden planks of the sand box were removed, smashing the molding sand that had been rammed by the orangutans to be as hard as a stone.

The gun barrel, which was a circle smaller than the original model, was exposed, and Xu Le carefully clamped it out with iron pliers.

At the same time, the mandrel slipped off from the barrel and rolled down.

He wiped off the fine sand on the surface of the barrel with a small hammer, and while the surface of the cast iron barrel was still red hot, he made minor repairs to the details.

This is mainly to ensure the tight fit of the installation.
