[Second Friday Bullet! ] It was sent at 12 o'clock, and it was sent in advance to now, begging for subscription!! Rolling all over the ground begging for a subscription :)]

"Poof! Poof! ”

With the hammer the size of a fist, the mud seal on the outside of the cave fell off, and some black and heavy honeycomb "coal blocks" also rolled down.

Wang Denghai was stunned for a moment, stopped tapping on the mud seal, and squatted down to carefully observe the "coal" that was still smoking slightly.

What the hell is this!

He thought angrily in his heart, just to burn these "coals", delayed his charcoal - the coal itself is used to burn things, but Childe used it to burn, isn't it a bit redundant?

But he didn't expect that wood was also used to burn things, and wasn't it also used to burn charcoal?

After knocking on the mud seal three or two times, he pulled those "coal blocks" into the rattan basket on the wheelbarrow, and pushed them towards his iron furnace -- no matter how much he complained, Wang Denghai did not dare to be disrespectful to his son in his heart.

He is just an ordinary blacksmith who is struggling on both sides of the Sand River, willing to do any job in order to earn food for his wife and children in the nest; Now, there is a tent for the rest of the year, the rice in the tent is enough to eat for a month, and the clothes on his body are all brand new, what is he not satisfied with?

Not to mention, I went back to my old job, and I got a salary of 2 taels of silver every month, which was a beautiful thing that I didn't dare to think of in Liaoyang City!

He knew very well that all this was given by this Chu Gongzi who forced him to burn "coals", how could he dare to have the slightest disrespect for this great and good man like Guanyin Bodhisattva? You know, compared to the villagers who are still struggling on the edge of the Shahe River, he is really lucky.

However, when pushing the wheelbarrow, he still habitually shook his head, Childe is good at everything. It's just that he loves to blindly command - this iron is his ancestral craft, when to put charcoal, when to blow wind, when to quench, that is all exquisite, how can it be messed up? Really!

When he pushed it to the iron-striking stove. The scene in front of him made him both angry and puzzled—Chu Fan and the two carpenters were squatting beside the iron furnace, loading a blower object made of cowhide and wooden planks, and his original simple blower lever was set aside.

Wang Denghai looked at it and still didn't say anything after all-if it weren't for Gongzi's own hands, if it weren't for the two carpenters, he would have rushed up to do it, this is the iron furnace that his father passed to him, why let them move!

Xu saw Wang Denghai's face pale, Chu Fan stood up, clapped his hands and smiled, "Master Wang." You turned out that this blower was too old, and it was leaking, so I asked them to make a new blower, you can try it. ”

Childe said so, what else can Wang Denghai say?

After adding the "coal" to the furnace and igniting the fire, Wang Denghai tried to pull the lever of the "blower", and immediately felt a difference in his hand -- compared to the old lever. This feels even more strenuous!

However, the effect was extremely obvious, and the stove suddenly became much redder. A wave of heat rushed to his face, which made Wang Denghai's heart get up - this "coal block" and this "blower" are really a bit of a doorway, is it true that Gongzi said that he can melt pig iron?

After asking another blacksmith to help him blow the air, Wang Denghai tried to pick up a piece of pig iron about a pound and carefully reached into the hearth.

As soon as he reached in, he was shocked in his heart - the firepower of this "coal" was so fierce!

It's different than when the wind blew just now. He was now closer to the hearth, and the heat was blowing in his face, and his eyebrows and beard were curled up a little—the place where he had been standing to heat the iron could not stand!

There's a door!

Seeing the strong firepower, Wang Denghai was overjoyed, how could he care about his eyebrows and beard being burned. His eyes stared at the gray-white pig iron in the hearth, and he didn't bother for a moment.

Gradually, the pig iron turned from gray to red, and finally Wang Denghai's hand loosened - the pig iron was really melted!

A strong force came from behind him, Wang Denghai was caught off guard, was pulled back, and almost sat on the ground.

He didn't care who pulled him, but his eyes were staring straight at the red piece of pig iron in the hearth—it should be said that it was no longer a piece of pig iron, but two pools of molten pig iron!

"Melt! It's really melting! Wang Denghai muttered in ecstasy, and wanted to rush forward to take a look, but found that his arm was being dragged by someone, and when he turned his head, it turned out to be Chu Fan Chu Gongzi.

"Childe, you really melted the pig iron! …… Oh my God! That's amazing! The blacksmith, whose eyebrows and beard had been burned, trembled with excitement.

"Master Wang," Chu Fan saw his gaffe and said with a faint smile, "This piece of pig iron was melted by you, not me...... The whole process, coking, ignition, and blasting are all done by yourself, remember? ”

After letting go of Wang Denghai's arm, Chu Fan said with a straight face, "Since the pig iron has melted, then this process has to be changed," he pointed to the wrought iron tongs that had been burned and deformed at Wang Denghai's feet, "You can't use iron tongs anymore, you have to use iron spoons instead, and the handle has to be lengthened...... This kind of wrought iron is no longer good, and it has to be more refined, and it must be ensured that it will not be deformed after the pig iron is burned. ”

"Yes, yes! I'll fight right away! Wang Denghai had not yet recovered from his state of ecstasy, and rushed to his pile of large and small pieces of iron with his hands and picked out a piece.

He really has good craftsmanship, and after repeatedly heating and beating this piece of wrought iron several times, a wrought iron pot the size of a sea bowl is formed; After adding a seven-foot-long iron handle to the wrought iron pot, a wrought iron crucible was made.

Holding this wrought iron crucible, Wang Denghai quickly boiled the first pot of molten pig iron, and poured the molten pig iron into the center of the wrought iron sheet in the sand mold amid Chu Fan's careful reminder.

After a sizzling sound, the molten pig iron glued the two pieces of wrought iron together, Wang Denghai and the molten iron had just solidified, so he picked up the iron sheet with tongs, put it on the iron felt and beat it violently, and when the iron was completely fused together, Wang Denghai quenched it with water, put the iron into the wrought iron crucible and heated it again until it was red and bright, and continued to beat it after taking it out.

After repeating this process four or five times, Wang Denghai finally quenched the iron in a large basin of water mixed with the urine and fat of the animals.

After taking it out and wiping it clean, Wang Denghai held this piece of iron of more than one pound in front of Chu Fan as if offering a treasure and said, "Childe, this iron material is the same as that Lumi gun...... If you melt the pig iron, you will save me a lot of work, and if an iron block of this size had been in the past, I would have to fight for a day and a night to make it...... Now it's been played out in three or five times! ”

Chu Fan took out his pocket watch and looked at it, Wang Denghai's four or five beats and quenching took almost three hours, and according to what he just said, Chu Fan knew that the steel filling method had improved the work efficiency by at least seven or eight times!

However, Chu Fan was not completely satisfied, and the next words made Wang Denghai, a person who has been fighting iron all his life, nod again and again. (To be continued.) )
