It seems difficult, but it is not difficult. Song Jiu knew that the technology was backward in this era, but if a large country had an iron production of only 1,000 tons, then some serious problems would definitely appear in the middle. He did not leave immediately and went to Kaifeng Prefecture again. He did not want to deal with the two kings. He was forced to go to the countryside in a mess and went to Xiangzhou iron pit to see the problem. He was not a god.

Zhao Kuangyi received him in the lounge, and asked the yamen runners to serve tea and fruits, which could not be considered a difficult task for Song Jiu. In this era, adding one million kilograms of iron is too meaningful. Song Jiu said straight to the point: "The two kings, I want to go and have a look at the Salt and Iron Department."

"Salt and Iron Department?"

"If you don't understand it as a whole, it may not be useful if you go down and read it."

"OK."

"The second request is that the court reissue the edict and inspect the rights of all pits on Hebei Road."

"Song Jiu!"

"The Second King, I know that this request is too much, but it is not really a patrol for all pit mines in Hebei. The first one is to see the operation of one or two iron pits, the second one is to see the steelmaking situation of cast iron, and the third one is to see the carbide mining situation, but I quickly return to the capital. The time of my minister is also precious. It will be time for three years, and I must pay the money and silk to the court at that time."

"Why do you need to look at steelmaking and carbon quarry mining?"

"I haven't seen the iron production now and can't judge it, but it is very likely that the iron of iron ore cannot be completely smelted out, and there are many iron impurities produced. As for steel, steel and iron are substances of different properties. Good steel is an iron-carbon alloy with a carbon content of no more than two percent."

"carbon?"

"It is the carbon next to the character "Stone", not the charcoal as the people say. With it, the strength of steel can be increased. Therefore, the Tang Dynasty's Modao can cut the war horse in half with one knife. If other elements are added, it will not easily rust, but the strength of that kind of steel is not very high. Then it can be replaced with different elements, which can increase the strength, which has corrosion resistance and toughness." Song Jiudao. In fact, with the help of some Song Dynasty techniques, in some theory, it can be realized to add carbon, chromium, manganese, molybdenum, silicon, and tungsten into the steel. There are two prerequisites, the first one must be Chao.

The Ting provided R&D funds and manpower, but individuals could not afford such a huge R&D cost. Secondly, although he could theoretically study various types of steel, whether it could produce energy is one thing, and how much is another. In addition to broadening his mind, some of the subsequent alloy steels that could not pass the test in this era were not very useful. The important one was still iron-carbon alloy steel. Moreover, he forgot and remembered many of the theoretical knowledge he had learned, and it would be very difficult to put the modern crafts of later generations into the current primitive craftsmanship.

If you are not in your position, you will not do anything.

If it weren't for the various buildings on the sandbank that would use a lot of steel in the future, he wouldn't want to do this more.

Say it casually and lightly.

It doesn’t matter whether you say it or not. The key is only one sentence. Steel and iron are substances of different natures. Zhao Kuangyi can’t understand other explanations.

"The object?"

"This Taoism is about studying these things."

"If you can increase one million kilograms of iron, I will correct your name in the future." Zhao Kuangyi said happily, and said: "Song Jiu, I will revise the edict again. I don't have that right, but I will report it to the emperor, and it's not difficult. But after you go on this trip, you must pay attention to one thing, select a few brave people from the river as attendants."

"Guard?"

"Secretary, what kind of guards! The court will also send two soldiers to protect your safety, but the country must have rules. The number of guards depends on the grade of officials, but the matter below will be a bit complicated. Your Majesty issued an edict to give you the right to inspect, just to facilitate you to have a comprehensive understanding. However, it will cause the people below to misunderstand and think that you are doing what you are going to do. If you are a few years older and have a higher official position, even if there is troubles in going down, it will not be very big. You can't do it now..."

"The two kings said that there will be greed for ink in the pits below? Why not deal with it? By the way, there will be no fish when the water is clear."

"What water is so clear and unfished! It's not what you think. In short, if you are smart enough, you can see it clearly after going down. If you are not smart enough, don't ask. It's your main thing to come up with a solution. If you don't distinguish between the severity of the matter and create some disputes, I and Your Majesty will not protect you at that time."

Zhao Kuangyi said this sentence has two deep meanings, but unfortunately Song Jiu did not hear it.

He brought Song Jiu to the Sansi until another person came out. Song Jiu vaguely felt the cautiousness of the Song Dynasty this time, that was Li Chongju, the envoy of the Sansi. However, after hearing about Song Jiu's miscellaneous things, Li Chongju saw that Song Jiu was still not serious, with a smile on his face and a strange expression.

Zhao Kuangyi didn't laugh and was always serious.

It was not forced, and it seemed that the kid was still keeping his back, saying something about carbon (coal) and steel. Is this materialistic learning so magical? But before asking, he was afraid of disappointment, and was afraid of forcing Song Jiu to be anxious.

The two big bosses took Song Jiu to the Sansi Salt and Iron Department. The Sansi was divided into salt and iron, the branch and the Ministry of Revenue. The salt and iron were the head of the Sansi, and were in charge of seven cases, soldiers, helmets, commercial taxes, salt, tea, iron, set up, and iron cases were divided into gold, silver, copper, iron, cinnabar, alum, green alum, carbonite, tin, and drum casting. Seventy percent of all the family backgrounds of the Song Dynasty were in this Salt and Iron Department. The information Song Jiu wanted to see was in the Iron Department of the Salt and Iron Department.

There are many officials busy. In the past ten, they see Zhao Kuangyi and Li Chongju coming. They have to be busy even if they are not busy. There are very few real officials, and there are many minor officials. If they have a promising future, the students of Song Jiu may have several people coming here to serve as minor officials in the future. There are also many people who have made trouble, and occasionally one or two small yellow gates will convey the news back and forth.

Song Jiu looked at it with a little curiousness.

Zhao Kuangyi and Li Chongju were also looking at him. Curiosity was destined. Any ordinary person who came to such a central organization would be a little curious. They looked at Song Jiu's expression. If they were like Liu Laolao, then the success of their lives would be the same. These are two words, demeanor!

They thought it was too amazing, and it was just a business building in Song Jiu's previous life, a slightly higher-end business building.

Song Jiu's expression was curious, but he was very calm. He was so calm that Zhao Kuangyi and Li Chongju felt pain and couldn't help but smile. Although this kid had no ambitions, he was brave. He brought it to the Iron Casino Department and Li Chongju asked the minor official to bring the equivalent iron and carbonite archives together.

Song Jiufu reads it in the information.

If you hadn't studied the ancient Chinese texts of Zhihu, you would have a headache when reading these materials. You would not mention the traditional writing, and you would write vertically, without punctuation marks, and no Arabic numerals. It would make you dizzy after reading them for a long time.

Song Jiu looked through carefully, it was really a look. Otherwise, what should I do?

Zhao Kuangyi and Li Chongju did not disturb him. Li Chongju ordered someone to bring a cup of tea and put it on the side of Song Jiu. Song Jiu was so impressed that he picked it up and drank it casually. The officials and officials in the iron case were a little displeased when they saw him being rude. If it weren't for the two big bosses here, they could have bombed Song Jiu out immediately.

Song Jiu looked through. The Song Dynasty ruled the north at this time, and the iron pits were also in the north. They were mainly divided into three places. The first place was the Laiwu area in Yanzhou, with eighteen subsidies, that is, eighteen iron ore production areas. The number was quite large, but the 18 iron ore production year was less than 500,000 kilograms a year, and one iron ore produced fifteen or sixteen tons of iron per year! It was such a large output. No wonder Zhao Kuangyi was anxious when he heard that he wanted 400,000 kilograms of iron. Look at this output, can you not be anxious? The second is the Xuzhou area, even less. It is mainly Xing, Xiang, and Ciyi on Hebei Road.

The Zhuzhi in the belt accounted for more than half of the national iron production. There were also some fragmented ore remaining. At the same time, it was found that Zhao Kuangyi said that the annual iron production was less than 2 million jin. This 2 million jin is the amount of iron, which means the amount of iron handed over by the imperial pits. Some of the iron in the middle must be lost to the people. There are also some private iron pits, but the quantity is even more pitiful. Maybe the iron that Li Blacksmith bought to build a pulley set was the lost private iron and private iron pits. But the total output will not exceed 4 million jin.

Look selectively, some are detailed, while others are not related, and you can just browse it.

What surprised him was that he had not seen any records of relevant smelting techniques.

"A little path." Song Jiu smiled bitterly. Dong Zhongshu killed someone. If there is another Zhu Xi coming out, will China get better?

I was in a bad mood and started to throw it around, put down the iron part, and started to look at the coal part.

Finally, they put down the file, Zhao Kuangyi and Li Chongju stared at him. The coal made them ignore it, and they saw a large amount of iron ore all their eyes.

Song Jiu said: "The two kings and Li Situans, the output is so small. No wonder many soldiers on the front line use cotton armor, paper armor, leather armor, and inferior armor."

At this time, the Song Dynasty did not have many troops, with only a hundred thousand soldiers, and only a hundred thousand soldiers. There were the Southern Tang, Later Shu, Later Han, and Khitan in the North. This force was necessary. It was not easy. For example, armor, different types of armor weighed differently, with an average of about fifty kilograms, but it had to be repeated hammered. There was a tempering process, and it was necessary to hit it once or less. If it was hit five or six times, it would take more than one hundred kilograms of iron. If it was refined, it would take ten or eight times, and two hundred kilograms of iron. Also, the weapons, arrows, guns and other weapons in the hands of soldiers used less iron, and only the tip was iron, but the iron was used for the knife.

The price is very large and the requirements are higher. Therefore, a good Park Knife on the market is priced at more than three jin of coins. It weighs more than ten kilograms, nearly two thousand jin, and a jin of kilograms reaches two hundred jin. If you are truly armed with the best steel, a soldier will need at least 300 kilograms of iron, and nearly 300,000 kilograms of soldiers across the country! The iron production of the Song Dynasty took more than fifty years to meet. The folks circulated Taizu Changquan and Taizu stick techniques, saying that the dragon stick used by Zhao Kuangyin is probably insufficient. Zhao Kuangyin used a wooden stick instead of weapons to smash the enemy's head. Cutting the false image on the surface, the truth will make people laugh and cry.

Song Jiu's arrogant attitude made some officials dissatisfied. A minor official said: "Boy, what are you talking nonsense? If the Tang Dynasty went to the west to the Pamir Mountains, to the north to the Goryeo in Liaodong, to the south to Jiaozhi, to the east to the sea, the annual iron production is no higher than that in our dynasty."

"The times are progressing, such as Carboniferous, which the Han Dynasty discovered. Why did our dynasty gradually apply? "Song Jiu suddenly stopped, thought of something, and whispered to Li Chongju: "Shi Shi, the officials in charge of the three departments must have a management mind. Should they try their talents?"

"How to try?"

"I asked a question and fold a piece of paper that is wide and long a hundred times. Who can do it? I will reward him with one hundred gold, and you will reward him with another hundred gold. If you think, you can stay for probation. If you rush to try it immediately, these people can no longer use it. If it is impossible, then you can train me for a while and reuse it."

"Nonsense..." Li Chongju originally wanted to say that this would not be easy to fold! It was not small paper, but the area of ​​paper with a length of one meter was as large as the length and width of one meter, but Song Jiu said that he would not be able to use it again if he tried it, so he shut up his mouth afterwards.

Zhao Kuangyi stood beside meditating and said, "Code, you can give it a try."

Li Chongju looked at Song Jiu suspiciously and said, "There are really successful people, don't cry."

The emperor will reward you with the hundred gold!

"Don't worry."

Li Chongju reiterated Song Jiu's words in the iron case.

Sure enough, there was a burst of cursing, calling Song Jiuhu Hu. Only half of them were pondering. As for the impossible, almost no one was there, and the rest had to try. There were no officials. They had to be reserved for their identities, mainly minor officials.
Chapter completed!
