"You use hot forging to create a scarf??"
After Li Lu arrived at the workshop of the Ministry of Industry, he saw that the craftsmen in the workshop were sweating and sweating on the heat treatment processes such as normalizing, tempering, quenching and annealing, and Li Lu immediately understood the problem."
What's wrong with Zhiyuan?
Don't all these processes are required for iron striking?
”Duan Lun was very puzzled, could it be that Jiankun's blacksmith still had any tricks?"
And ask me what's wrong?
Didn't I say that the real name of this cold forging armor is cold forging armor, don't you understand the three words cold forging armor or what?
”Li Lu was very angry, and he kindly taught them the cold forging process, but people thought that this process was too low, and continued to use the hot forging process that he thought was superior.Li Lu is so angry.Li Lu carefully inspected the nail pieces made of fine iron from the iron smelting workshop of the Datang Ministry of Industry, and found that they were all made of hot forging without exception."
You have a good look, after annealing and quenching and tempering to eliminate stress, you can't use fire, you have to hammer and forge naturally, and the selected fine iron must have good ductility and toughness, otherwise in the end, just like these waste products you make, it will break."
Li Lu called these craftsmen over and told them this."
Little Wangye, the kind of iron you said is called 100 steel, the output is very small, good steel should be used on the blade, if all of it is used to make armor, this ......."
The most respected old Song Tou in the workshop looked embarrassed."
What, you say this is called 100 steel?"
Li Lu wondered, in his memory, the Xixia technology he used to make the Qizi armor is made of iron instead of steel, after careful inspection, Li Lu found that even the old Song Tou said that the hundred steels are actually not suitable for cold forging, it seems that he is lucky enough, the refined iron produced by the iron ore he occupies can be cold forged with a little treatment.Oh, I remember, in my previous life, I read the great scientist Shen Kuo's "Mengxi Writings" and mentioned that the people of the Song Dynasty could not make real Qizijia with the raw materials of the Song Dynasty, just like the Song Dynasty in which Shen Kuo lived, the materials from the Tang Dynasty did not have the conditions for cold forging, so that the method of cold forging could not be processed at all, either too soft or too hard, and the result of such processing was that the nail piece eventually broke due to metal fatigue.Therefore, Lao Song Tou can only use the method of hot forging to process the nail piece, and the final appearance is like that, but the performance is completely different.The hardness of the armor piece and the structural strength and impact resistance are a pair of contradictory pairs, the higher the hardness it is, the more brittle it is, and the higher the plasticity, the softer it is.In order to achieve sufficient surface hardness and impact resistance, the basic properties depend on the material, in addition to the processing method.The source of the material is the geographical resources under natural conditions, which is innate, which is not solved by the current Datang.......
The heat treatment technology in hot forging is the most test of craftsmanship in metal technology.Let's put it this way, the most important thing to grasp in this heat treatment process is the problem of fire temperature, in this era there is no equipment to detect temperature, all based on the personal experience accumulated by craftsmen for a long time, that is, the same person, at the same time play a few handfuls of the same thing, there is also a difference in softness and brittleness, the success rate is very low, it is not easy to create molding, and it is difficult to become a genuine product in the last hand.This is also one of the historical reasons why heat treatment technology has lagged behind the West in later generations.Well, you said that heat treatment hot mass forging armor pieces?
I'm sorry, that's just a luxury, it's okay to play swords, it's hard to hit armor, not to mention how many people can master this technique, even if there are many such talents, then we have to see if we can meet the needs of making swords first!
After listening to Li Lu say that Datang's pig iron is unqualified, Li Ji, Li Jing, Hou Junji and other generals of Datang are extremely unwilling, but they are helpless, although this cold forging armor is very simple and effective, and the technical requirements are not high, but cold forging has high requirements for the fatigue resistance of metal, and not pig iron everywhere is suitable, which is the case with Datang at present.What if you are unwilling?
I thought it could effectively reduce the production cost of Datang armor, but I didn't expect that in the end, it was still a bamboo basket for water, but fortunately, Datang's Mingguang armor was not worse than the Mingguang armor at all, so use Mingguang armor......
After returning to the palace and resting for a while, I saw Ma Changqing roaring anxiously to find himself, "Lord, please save the old daughter-in-law......."
Ma Changqing followed himself to Chang'an, and his family gathered, after the old man Ma came to Chang'an, he has been busy with Jiankun's bone china, spirits, glass and other specialties for market expansion, the day before yesterday his son told Lao Ma that his daughter-in-law was about to give birth, and Lao Ma returned to his hometown three miles outside Chang'an City, this came to find himself, is it?"
Ma Lao, you speak slowly, don't be in a hurry!""
Lord, I can't help but be in a hurry, no matter how late it is, there will be two lives in one corpse, my good prince, please......
"One corpse and two lives?
Oh, my God!
Li Lu was startled, he hurriedly went out of Chang'an City with Ma Changqing, and when he came to the Ma family's old house, it was already late, Ma Changqing's daughter-in-law still didn't survive this life and death pass, and when the Ma family was grief-stricken, Li Lu found an important problem, the Ma family's unborn child was still a deformed child."
Ma Lao, is your daughter-in-law related to your son?"
Li Lu thought about it and asked Ma Changqing and the rest of the Ma family."
Back to the prince, Xiaolan is my cousin......"
Ma Changqing's son Ma Yuan said very sadly."
You guys, don't you think that you have decided on this family ???
affair because of your kisses?"
Li Lu said."
Yes, little prince, isn't this my aunt's cousin, kissing and kissing?"
Mrs.
Ma said with tears in her eyes, her daughter-in-law is also her niece, this difficult birth is gone, can she not be sad?"
You, you.......
Where is this kiss and kiss......
Let me tell you, even if your daughter-in-law can give birth to a child safely, that child is also defective, I just saw that the ear and nose are not fully developed, and he will not survive at all.Any idea why this is?
It's because your son and daughter-in-law are too close by blood!!
”Li Lu said."
Huh??
Doesn't that mean that I hurt Xiaolan???
”Mrs.
Ma was even more sad, that is, she was planning to marry her niece Xiaolan, but she didn't expect that she had harmed her.....
As for whether Li Lu is right or not, the Ma family thinks that what Li Lu said is right, that is because Li Lu knows how to heal, many people in Chang'an know about it, and Ma Changqing knows Li Lu's magic, and their family is convinced of his words.After comforting the Ma family for a while, Li Lu remembered Li Li, who often pestered himself to be coquettish, and in a few years, this little Lori was married to his own uncle and brother Changsun Chong by his father and queen mother, just when he was thinking nonsense, Changsun Chong came to find himself for this goods, saying that the eldest grandson and the old fox invited him to come to the house, and the old fox looked for himself because he looked at his iron-making skills, right?

It just so happened that I also wanted to remind the old fox that although the eldest grandson and the old fox were not above board in the history books, but after he came to Chang'an, the old fox was not bad to himself.Li Lu has always been a person who respects me, and I am a person."
I said worm, my brother told you something, you listen....."
On the way to Changsun Mansion, Li Lu rode on a horse and said to Changsun Chong."
Brother Zhan, if you have anything to say......"
Changsun Chong approached Li Lu under the instructions of the old fox, and after contacting Li Lu, he found that this little prince was not simple, so Changsun Chong had become Li Lu's fan brother."
What my brother said is you, don't fight Changle's idea, don't frown, this is for you and your eldest grandson's family!!"
Li Lu looked at the somewhat frantic eldest grandson Chong and said."
Brother Zhan, what do you mean by that?"
The eldest grandson Chong looked puzzled."
I'll tell Uncle Eldest Sun about this later......."
Li Lu said as he came to Eldest Sun's mansion."
Uncle Eldest Sun, your love for the little nephew, the little nephew is in his eyes, the little nephew is ready to leave Chang'an, and there is nothing to send, so I will send you some methods of smelting iron and steel, please refer to Yazheng......"
Li Lu got straight to the point, making the eldest grandson fat man very surprised, "Virtuous nephew, this is the hard work of your family for several generations, you just sent the old man......."
The eldest grandson fat man can't help but be surprised, these years, which family is not strictly guarded against these heirloom treasures, and is deeply locked in the family's heavy land, Why did this little baby do the opposite?"
Uncle Changsun, your eldest grandson's family has mastered one-third of Datang's iron output, and your eldest grandson's iron output has gone up, which is not equivalent to increasing Datang's strength in disguise!!"
Li Lu took a sip of tea, "Uncle, the little nephew is not without requirements, you have a huge influence in the center of the court and the government and the opposition, just provide some protection for the little nephew's Kunjian business group!"
”"Hehehe, look at what you said, these things are not difficult for the old man......."
The old fox heard it, ouch, this old man is willing, the glass, bone china, and spirits produced in Jiankun are all good things, and if you provide protection for this kid, then your eldest grandson's family will definitely get a lot of benefits.Seeing that the major matters were negotiated, Li Lu told him what he saw in Ma Changqing's house, and then said to the eldest grandson Wuji that he knew that the eldest grandson Wuji wanted to marry Princess Changle for his son, Li Lu persuaded him not to do this, because he and his own master found that all blood relatives within three generations in the process of practicing medicine, as long as they are married, the probability of problems is extremely high, and in the end, Li Lu said to the eldest grandson Wuji, "Uncle eldest grandson, if you don't believe it, you can go to the household department to check the population records and see if what the little nephew said is true or false." ”"Hiss......."
The eldest grandson of the old fox took a breath of cold air, Li Lu's medical skills are very high, he knows, since Li Lu dares to say, it means that he has sufficient evidence to support his assertion, "Zhiyuan, don't scare the old man, this is related to the trend of the Tang Dynasty's centennial national fortune.......
"In ancient society, what is national strength, national strength is population, food and steel."
And the most important thing in this is the population, if there is not enough population, there is no matter how much food and steel can be used.
