Coal.
Undoubtedly the founder of the industry of later generations, or the guide?
The earliest large-scale utilization of coal in China should have been before the Spring and Autumn Period and the Warring States Period, or even earlier, but the use of coal for metallurgy began in the Han Dynasty.
The mining of ores, including the production technology of black minerals such as coal, was relatively mature in the early Han Dynasty. Large-scale mining tunnels and the use of mines were already considered to be the world's top standards. However, due to the demand of gentry for charcoal,
It was relatively large and looked down upon coal, so for a long time it didn’t pay much attention to coal, let alone demand for pure coal.
Now……
Coal is needed for heating, and coal is also needed for metallurgy. The demand for coal in the Huqi territory has suddenly increased a lot. In addition, with the cold weather now, the demand for coal from ordinary people has also increased sharply. This
This forced Fei Qian to consider improving the original coking coal refining process.
In the past, coking coal was refined using the most crude and stupid method, which was similar to burning charcoal. The coal was first piled up in a semi-enclosed space, then ignited with firewood, and then allowed to burn in an environment lacking oxygen.
Burn slowly, let all the smoke and impurities in the coal fly away from the chimney, and when the smoke no longer comes out of the chimney, pour water in...
Finally get coking coal.
This method can be used, but it is very wasteful. Most of the coal will be burned in the process, and the remaining coking coal may only be about 30% of its original weight, or even none.
Therefore, using this method to obtain coking coal specifically for steelmaking is indeed quite costly.
At the same time, in the process of steelmaking, if molten steel cannot be continuously produced, the coking coal invested will often be wasted. In other words, due to the discontinuity in the production of molten steel, part of the heat energy from the burning of coking coal will not be used at all, and it will be in vain.
It was just burned.
When there was a lot of coal, these problems were not serious, but now the amount of coal is large, and some miners in Luliang Mountain have to stop their field operations because of the cold weather...
What?
High temperatures in mines?
There is nothing wrong with this, but Feiqian's mining technology is not like that of later generations, where it can easily dig a mine several hundred meters deep. Generally speaking, it is still a surface mine development.
Therefore, output has decreased and demand has increased. Although there is still inventory, we cannot wait until the storage is exhausted before we consider the issue of raw materials consumed in the production of coking coal, as well as the efficiency issue when using coking coal. We must first take the lead and carry out
Certain process improvements.
The task of improving this process naturally fell to the newly appointed "Grand Examination Engineer" Huang Chengyan.
Of course it was difficult for Huang Chengyan to think about these things, so he summoned several big craftsmen to discuss it together. This was also the habit of Huang Chengyan's craftsmen. After all, one's thinking is always somewhat limited...
But coking coal itself was already developed by Fei Qian ahead of time. Now it is undoubtedly a very difficult thing to take it a step further. Therefore, Huang Chengyan has been a little distracted these days, which makes Huang Yueying extremely worried.
, I thought there was some big problem, but it turned out that Huang Chengyan had no physical problem, it was just because of the craftsmanship...
Huang Yueying was immediately furious!
Thinking about it, it’s no wonder that his son was about to go to Yinshan Mountain to suffer hardship after being tortured by Fei Qian, and then his father is now being tortured by Fei Qian and doesn’t even think about food and tea...
Whose fault?
Who else could be at fault?
The more Huang Yueying thought about it, the angrier she became, and angrily she found Fei Qian.
Fei Qian was a little confused at first, but after understanding what happened, he couldn't help laughing.
"Come on, sit down first, sit down first, sit down and then talk..." Fei Qian greeted, "Do you think I am tossing? Haha, no... This has nothing to do with tossing..."
"Listen to me first..." Fei Qian said with a smile, "... Qi was greatly hungry. Qian Ao prepared food on the road, waiting for the hungry to eat... There were hungry people who gathered their clothes and hurriedly gathered them.
Come. Qian Ao held the food on his left and the drink on his right, and said, "Hey! Come and eat! Well... Yueying, you should know this?"
Huang Yueying snorted, "I don't want to eat the food I came to, so that's what I am doing!"
Fei Qian nodded and said, "That's right. So...why don't hungry people eat? Isn't it just to come and eat? In the end, you will die if you don't eat. When Zengzi heard this, he also sighed, "It's okay to go away.
You can eat it if you thank me." Yueying thinks, at this time of hunger, what should we eat and what should we eat?"
Huang Yueying frowned and fell silent.
Huang Yueying is naturally aware of this matter. After all, Huang Yueying herself is considered to be from a noble family. Although it is not as good as Cai Yan's library... Well, okay, not everyone can compare with the library, but some basic spring and autumn works like this
I still know some of the allusions.
"Come to eat", the hungry man in the allusion chose to starve to death rather than eat. This is an attitude. Another attitude is like Zeng Zi said that if it is "Come to eat", it will not work, but
"Qixie" can also be eaten.
As for there is another kind, it is the famous attitude of later generations...
In fact, Huang Yueying didn't understand what Fei Qian said. It was like Fei Qian said that he wanted Fei Zhen to take a trip in the military. Although Huang Yueying felt distressed, she agreed, but sometimes her emotions got the best of her.
, it’s inevitable that you can’t control it.
For ordinary people, no matter which attitude they choose, the problem is actually not too big, but it is different for leaders...
Fei Qian's status was established in the army during the Southern and Northern Wars. Even now that Fei Qian is no longer on the front line commanding operations, as long as Fei Qian talks about military strategy, Fei Qian's words will be followed by others.
Don’t dare to say anything!
This is the strength that Fei Qian showed in previous battles, and the prestige he accumulated bit by bit. However, whether it is Fei Zhen or Huang Chengyan, they are in Fei Qian's political group, except that they have a closer relationship with Fei Qian.
,did you show any special strength?
"Therefore, my father-in-law doesn't think about food and tea. This is the right way!" Fei Qian said with a smile, "If my father-in-law just occupies a high position, shouts and drinks, but has difficulties, he is shirk... then what can others do?
Can you respect him with respect? As the saying goes, knowing the difficulties and... well, there is a saying that is right, if you want to wear his crown, you must first bear his weight..."
Huang Yueying sighed softly, then bowed to Fei Qian and expressed her apology, "Mr. Lang... I am in a hurry, so I have offended you..."
Fei Qian stepped forward and helped Huang Yueying up and said: "It doesn't matter, it doesn't matter... When my father-in-law was in Jingxiang, he once told a certain person that he prided himself on being a master of painting, painting, making, copper, coating, buckling, painting, and craftsmanship.
, Qing, You, Kao, Ye, Tong and other construction methods are all omnipotent and masterful...Now, hehehehe..."
Huang Yueying couldn't help but rolled her eyes at Fei Qian, and then sighed and said, "Lang Jun knows it well... My father is a bit older after all..."
Fei Qian chuckled twice, "Don't worry, if my father-in-law really can't think of it...then I'll pretend to reveal it unintentionally..."
"Huh? (﹁﹁)~" Huang Yueying said with her hands on her hips angrily, "Could it be that Mr. Lang has a wonderful idea, but he is here to watch my father's jokes?!"
"No! That's not the case!" Fei Qian immediately denied, "I just said that we can discuss it together at that time, well, we will discuss it!"
……o(TT)o……
Youbei Desert.
Another group of people who didn't want to eat the food gathered together...
The horn of advance finally sounded. Kirby's troops began to move slowly, speeding up little by little, and the sound of horse hooves gradually became denser.
In Kirby's central army, the messengers were like a flock of birds flying out of the tree nest, passing instructions outwards with fluttering edges, while the buglers were also preaching with all their strength, passing on the latest instructions.
to distant places.
Liu He finally realized that something was wrong. It was like watching a beautiful woman's live broadcast, and then suddenly the other person's phone lost power and turned off the beauty and falsetto software...
Reality is always so ugly, there is no so-called beauty at all, only the hard and smelly thing is left, directly in front of you, shattering all your dreams.
"Get ready to fight!" Nan Lou shouted loudly first, and then drew out his sword. As for going to Liu He to reason about why it happened like this, why Liu He made mistakes in judgment, and who should bear this responsibility, etc.
All the problems are there. Only when the battle is over will you have free time...
After all, reality is not like movies and TV shows. On the battlefield, when two sides are fighting bloody battles, especially in the era of hot weapons, there is still time to stand in front of the battle, babble a lot, express a lot of emotion, and then
The surrounding soldiers were able to shed tears with them. Isn’t it possible that only a mentally retarded director could have filmed it?
Forget about cheating money, but also insult the intelligence of the viewers?
Nanlou raised the sword in his hand and shouted loudly: "Speed ​​up! Speed ​​up! Come on!" In fact, Wuhuan people may not all understand what the so-called array is, but they do know one thing. If there are more people, you can bully the less people. Surround them and surround them.
Just hit it and that's it.
The sound of horns sounded one after another, and the sound of horse hooves rolled like thunder.
Of course, if Kirby can deceive Liu He and others into his camp, then things will be simple. But the problem is that Kirby can now, and the Xianbei people have lost such qualifications. So once the two armies really do
When they sat down for a meeting, Kirby must be deeply involved in the opponent's military camp, so Kirby chose to make a surprise attack.
Although the Wuhuan people were somewhat caught off guard, they had the advantage in numbers and were not much afraid. The horses on both sides suddenly accelerated, and countless horse hooves hit the remaining snow. Mud, water, and snow splashed everywhere, and the whole land seemed to
They were all trembling.
Kirby Neng's troops, with Kirby Neng as the center, were like an awl and a murderous sword, piercing directly into the Wuhuan array and towards Liu He's position.
To be continued...
