↓Here is an explanation of the remodeling of the blast furnace↓

↓Flip down quickly to increase Lin Yuan's construction speed↓

After Lin Yuan no longer took care of Tie Niu, Tie Niu could only helplessly go to the house to cook for Lin Yuan.

Seeing that Tie Niu was walking away, Lin Yuan stood up and began to look at the blacksmith shop.

The facilities are very simple.

There was a large stove with a wide bottom and a narrow bottom, and then an opening was made outward to add materials and burn iron.

A chimney is attached to the top of the stove leading to the roof, and on the left there is a hand-pulled bellows, which can be pushed and pulled to blow the air.

The stove was facing a rudimentary iron felt, and hammers of various sizes were placed on the wall.

After looking around, Lin Yuan closed his eyes and pondered.

The first thing that comes to mind is the earth blast furnace in the period of great strides in later generations, which is simple to build, low cost and high output.

As for the current situation, Lin Yuan only needs to improve it a little and turn it into a furnace, throwing some iron into it and melting it is not a problem at all.

First of all, the outer wall of the furnace must be thickened, the large mouth of the firewood should be sealed, the bottom of the furnace needs to open a taphole, the taphole is slightly higher to open a slag outlet, and the large chimney above cannot be connected with the furnace, because the top of the furnace should be removed and replaced with a feeding port.

Lin Yuan believes that the monopoly of blast furnace ironmaking should be the design of the top feeding, feeding sequence and slag outlet, and Tie Niu, a professional craftsman, must understand it at a glance, but if he has never seen it in his life, it is impossible to understand the Tao.

Directly use the furnace to make iron, the temperature is not up to the difficult to melt iron, not to mention, the waste slag at the bottom of the furnace accumulates too quickly and cannot be refined too much, and the furnace will be wasted.

The small people will definitely be disrupted or even smashed and burned by the powerful in various names, and their lives will be difficult to protect.

Considering that coke is used in molten iron, the performance of coke in the Ming Dynasty is not estimated to be too good, and if the combustion is not sufficient, it will smoke and generate carbon monoxide.

Both carbon monoxide and smoke drift upwards, so the chimney is changed to a large inverted funnel, facing the stove, so that the smoke exhaust problem is solved.

The funnel is made of wood, and then used first, and then the iron is melted out and then changed to iron.

Lin Yuan said to himself: "It's very simple, the general direction of the furnace transformation has come out!" The rest is the small details. ”

Lin Yuan suddenly felt that something was not right, when did he become so smart, such unpopular knowledge completely came out of his own thinking when he was thinking, some of it was completely unheard of before, and his predecessor did not have such a strong thinking ability.

↑ Lin Yuan: "I am optimistic about you and understand the preciousness of time." ”↑

Lin Yuan: "It's not that I have a system. ”

(*´I`*)

Lin Yuan: "Xiao Tongzi came out." ”

In the blacksmith shop, Lin Yuan stood motionless.

The eyes are still glancing from side to side, looking forward to whether there will be a ding~ sound in the head, and then a powerful system will come out of the head, and he also fantasizes about joining hands with the system to dominate the Ming Dynasty and conquer the world.

Five minutes later~

Nothing happened.

"Brother Tong~"

"No"

"Master, you just come out~"

……

Ten minutes have passed~

……

Lin Yuan was desperate, he even tried to hit the wall to summon the system, not all the novels used to be when the protagonist was in danger, and his brain suddenly popped out, 'Ding Dong~xx The system has been activated....... ’

It's just that he was afraid of pain, and he was deflated before his head touched the wall.

There was no way, Lin Yuan could only return to reality, and began to carve what he had just thought of in stone behind the door of the blacksmith shop.

Paper and pen are now a luxury, and it is not a luxury, as long as the iron bull can understand it.

After Lin Yuan finished drawing, Tie Niu happened to have a bowl of chicken soup in his left hand and a plate of chicken in his right hand, and walked out quickly.
