Outside the iron-smelting workshop, Li Chengqian was squatting by the river, holding a straw stick in his mouth, and Xiao Tang was standing behind him.

The old things are tired, they are all looking for a place to rest, after all, they are all people in their sixties, and the old man is even older and is about to lose his scum, and it is not easy to walk around the ironworks with him, and then let him accompany him, it can almost kill him.

"Xiao Tang, haven't you thought of any special solution?" Li Chengqian, who was squatting by the river, suddenly asked.

"I thought about everything I could think, increase the blower, increase the air intake, I thought about these but there was no way, that is, if it can't be burned, it can't be burned, and the raw materials are burned half, and they can't be turned at all." Tang Shanzhi said.

"What about the other way? For example, replacing the burning material or something. ”

"It's useless, I've even tried the water, but the result is not as good as coke." Tang Shanzhi kicked the stone under his feet a little hard.

"Alas......" Li Chengqian also sighed, this is actually the limitation of production technology.

If it is placed in the later generations, there are many ways to achieve alloy refining, but in Datang there is only this one method, which makes it very annoying at the same time, but there is nothing to be done.

But then again, Li Chengqian actually vaguely remembered that there was a way to increase the temperature of the fire, but he was too anxious at the moment to think of anything.

It's like having thought about what to write for tomorrow's two chapters last night, but when you wake up from sleep, you can't remember what you had in mind yesterday.

Of course, I believe that readers have also had this kind of experience, as if everyone is chatting together, you obviously think of a problem, but someone interrupts it, and then you can't remember it anymore.

Li Chengqian is in such a state now, so he squatted by the river and thought hard, thought hard, and thought like crazy, but the more he did this, the more he couldn't remember.

In the end, he simply spit out the straw stick in his mouth: "It's a donkey day, I don't want to do it, why don't you love it!" ”

Tang Shanzhi thought that Li Chengqian had thought of something, but when he heard that it was 'why is love', he immediately collapsed, pulled Li Chengqian and said: "Don't, I said Gao Ming, you can't ignore it!" ”

"What Lao Tzu does, Lao Tzu can't control it himself." Li Chengqian said angrily.

Tang Shanzhi stopped talking, squatted on the ground, and looked up at Li Chengqian, his little eyes were like a poor little milk dog.

However, Xiao Tang obviously made a mistake, if it was Meng Mei Paper's expression like this, maybe he could exchange some sympathy from Li Chengqian, and Xiao Tang's Han Paper, who was in his twenties, could only get a palace-style beating at most.

……

After finishing the matter, Tang Shanzhi looked at Li Chengqian, who had a long nosebleed, with two dark blue circles: "You were the one who beat people, why are you worse than me?" ”

"Less nonsense, let me beat me again, don't fight back, I'm about to think of a way." Li Chengqian tried to tilt his head up, as if this would allow the nosebleed to flow back again.

"Do you think I'm stupid?" Tang Shanzhi rolled his eyes, thought about it, and probably felt a little unwilling, smacking his lips and saying, "Otherwise, you can record it in the account first, if your method is really feasible, I will let you beat ten times." ”

"No problem, you can go home and ask your wife for leave, and say that you will stay in the hospital for a period of time, and you will not go back for three or five years." Li Chengqian's nosebleed stopped at this time, and he looked at Xiao Tang and laughed.

A bastard on a donkey day, he dared to fight back when he was beaten up just now, and he broke his nose, if this revenge is not avenged, the reputation of 'Jianwei will be avenged' in the future!

But Xiao Tang is not stupid, he is also afraid that Li Chengqian is lying to himself, in case he is asked to fight again, but after the fight, he can't think of it, wouldn't he have been beaten in vain, with this kid's (read four tones), he can do this kind of thing.

So Xiao Tang shook his head firmly: "You say it first, I'll think about it after I finish speaking, if it's really possible, even if I am killed by you, I am willing." ”

"Okay, it seems that you kid really doesn't cry when he doesn't see the coffin, and if he doesn't give you a little power, you don't know what the smartest person in Datang is." Li Chengqian, who had already made up his mind in his heart, spat on the ground fiercely, sat on the ground without the image of a prince, and hooked his finger at Xiao Tang.

Xiao Tang naturally wouldn't continue to stand stupidly at this time, and also sat down beside Li Chengqian: "Say, I'll listen, if the method is really good, I will hand over the more than 100 catties to you to toss." ”

"Hehe...... Li Chengqian laughed and didn't answer, just looked at Xiao Tang and asked, "What do you think of adding another blower?" ”

"Not good, I've already added it." Tang Shanzhi shook his head.

"This time we added a different one, we added a blower that blows hot air." Li Chengqian glanced at the dejected Xiao Tang beside him, and continued: "What do you think will happen if a fire is lit in a cold house? Will there be a certain amount of temperature wasted in heating up the room? ”

"Of course it will, but what does it have to do with our iron control." Tang Shanzhi said with a frown.

"The truth is constant, don't you think that part of your furnace temperature is wasted on raising the air around you? The air flow blowing in your blower is cold, and your furnace fire will inevitably waste some of it to raise the temperature of this cold air before it heats up your crucible. ”

Although Tang Shanzhi had been listening hard, he finally shook his head: "Oh, Gao Ming, just say what to do, I don't understand the principle you said." ”

Li Chengqian also seemed to realize that his efforts were in vain just now, so he sighed and said: "I mean, if you heat the air first, and then blow it into your steelmaking furnace, it should solve the problem of insufficient furnace temperature." ”

"Heating the air?" Tang Shanzhi repeated Li Chengqian's words with some uncertainty, and the person fell into deep silence, as if he was considering the feasibility of this matter.

"There is no other way, now it can only be like this, you guys start first, if this doesn't work, then you can only think of other ways to settle it." Li Chengqian stood up on Tang Shanzhi's shoulder, and looked back at the iron-smelting workshop that was still busy: "Don't worry, it should be successful." ”

"Okay, I'll arrange someone to try it, hot air, Lao Tzu will immediately move two brick kilns over, isn't it just burning air, it's not a big deal." Although Tang Shanzhi did not think that Li Chengqian's method would definitely succeed, it could be regarded as a method at the moment.

And if he didn't do what Li Chengqian said, he didn't have any other way, and he treated the dead horse as a live horse doctor, so Xiao Tang decided to fight.
