A simple bark,
Can you play so many tricks?
Just a little modification.
Just become a blower?
This is too arrogant!
Seeing this operation by Lu Yu.
There was an uproar in the live broadcast room, and various gifts appeared one after another. It took a long time to calm down!
but.
In awe, many water friends also said:
This type of fan with built-in fan blades is too inconvenient.
You can only work if you keep rubbing your hands.
If you use this guy to heat up the charcoal fire, isn't it possible that you can't be competent if you are single for fifty years?
The most important thing is that watching is also tired!
Copper smelting is a big project. When will this be the first time?
Faced with doubts from some viewers.
Lu Yu smiled heartily.
Signal everyone not to worry:
"Everyone, this is only a semi-finished product, please rest assured, and then look down--"
Talking.
He turned around and randomly found several branches of varying lengths.
A small wooden frame with a "gate" shape was built with bark rope.
Placed above the blower.
Then, I took out the spindle that was made when weaving the cloth.
"Remember this spindle?"
"When I built the textile machine, I said that the spindle can be used as a bow drill in addition to turning the thread into hemp rope."
"If you apply it to a blower, everyone's concerns will naturally be solved."
The bow drill, as the name implies, uses a bow to drill.
Mostly used for drilling wood for fire.
This method of making fire should be one of the most convenient and fast methods among all methods of drilling wood for fire.
save time and energy.
Very efficient.
More powerful than hand drill.
In addition, in other respects, bow drills can also perfectly replace manpower.
Automatic blowers are one of them.
Speaking room.
Lu Yu held the spindle.
Remove the round stone plate below.
Randomly found a bark rope tied at both ends and transformed it into a wooden bow.
Next, wrap the bowstring of the tree rope onto the drill rod of the fan.
It was fixed on a small wooden frame.
This way.
Just hold the end of the bow drill with your hand and keep pushing and pulling.
The fan blade of the blower will naturally rotate with it!
Not only is the wind lasting and strong.
The most important thing is that this is much easier than simply rubbing with your hands!
After doing well, Lu Yu didn't say much, and demonstrated it to the audience on the spot!
In the picture.
With the bow string one by one.
The fan blades in the casing sometimes rotate forward and sometimes reverse.
In an instant.
The sound of the wind came from the air outlet, and the charcoal fire was blown in a moment!
See this picture.
The audience immediately lit up and left messages in the barrage:
"Lying slot! Wonderful!"
"This blower is invincible!"
"It's so clever!"
"666666666"
"The anchor's manual ability is really strong!"
"This wind power matches some of the five-speed electric fans!"
"Upstairs so well understood? Are you passing?"
"Hahahahahaha!"
...
quickly.
After a large wave of gifts, Lu Yu simply thanked a few words:
"Thank you for your gifts."
"Actually, this is just a very simple automatic blower, it is not difficult to make at all."
"The main structure, except for the fan blade and the shell, are all materials that are usually within easy reach."
"The principle is simpler and clearer, but any normal person can think of it."
"However, in order to perfectly apply simple principles to daily production and life, in addition to being good at discovering, you must dare to try."
"Because, in the final analysis, it is precisely time and time again that it has allowed human civilization to go from poor to inferior to today."
"How are you, brothers? Is this blower interesting?"
Not only is it interesting.
It's too TM show!
The simple principle that no one knows, plus a few inconspicuous things pieced together, can play so many tricks.
Disobedience is not good!
This scene almost perfectly interprets the unique charm of the original survival-
Use the materials at your fingertips to create your own world bit by bit!
...
After two hours.
Lu Yu set aside the prepared blower.
Going to the charcoal kiln, through the ventilation holes below, leaned over to observe the fire inside.
At this point, the fire above had completely spread to the bottom of the kiln.
The wood underneath was red.
"Everyone, it's almost the same as firing..."
Withdrawing a large piece of clay from the bamboo basket, Lu Yu went on to say:
"The next step, all we have to do is plug all the vents with mud."
"Including the opening above the kiln roof."
"The purpose of this is to slow down the burning rate of charcoal and allow it to fully carbonize. At that time, as long as all the volatile gases overflow, you are done."
"The whole process may take a while, so we have to wait for a while."
Taking advantage of this time, Lu Yu casually ate something to replenish his energy.
Subsequently, he ordered the stove again.
A fire was rearranged.
And take out most of the remaining mud.
Surround the fire.
A small cylindrical furnace was built round by round.
"Someone in the barrage asked, why do you have to make another furnace when you have a clay kiln?"
Looking at the barrage, Lu Yu explained:
"In fact, it is very simple. The bigger the kiln is, the better."
"For smelting metals, small furnaces are easier to concentrate temperature than earth kilns. Secondly, because of our limited materials, if earth kilns are used, more charcoal will be wasted, so it is necessary to build a small furnace separately."
Speaking room.
Lu Yu smoothed the edges of the furnace with his hands.
Then, at the bottom, a moderately sized carbon outlet and air inlet were opened respectively.
The role of the air intake is obvious.
Just to connect the blower of the blower!
The role of the carbon outlet is also well understood.
With it.
After the refining is completed, the copper material reduced by charcoal fire and high temperature can be easily searched out from the furnace.
The function is not much different from that of the charcoal kiln.
...
Live broadcast here.
With a blower, furnace, ore powder and charcoal, the preparatory work has basically come to an end.
Next.
As soon as charcoal comes out.
You can throw the ore powder into the furnace.
Smelted with charcoal.
By the time.
After continuous refining at high temperature, the copper contained in the ore powder will naturally be gradually reduced back to copper.
After that, it is only necessary to melt the copper material into liquid copper.
Pour into the mold.
You can become the shape you want!
Such as axe blade, blade.
Even the arrowhead is no longer talking.
...
Time is flying fast.
It was two o'clock in the afternoon.
Waiting for the time for charcoal to come out.
Lu Yu was not idle.
Have been chatting with the audience one sentence after another.
It wasn't until the green smoke at the entrance of the charcoal kiln stopped volatilizing that it stood up and walked over to check.
To the kiln.
He first touched the temperature of the kiln wall with his hands.
Then, he probed the fire on the roof of the kiln again.
It took a while to say:
"Friends, it should be almost burned."
"Gossip less, let's take a look first, what's the situation inside—"
