Fu Ziyun opened the wooden box, took out a cloth bag from the wooden box, and spread it out, revealing the wrapped things, including two black stones, a piece of iron wire wound in a spiral, and two inconspicuous small iron balls, as well as something that looked like a pig iron block.

Fu Ziyun took out one of the black stones like a treasure, sent it to Xin Qiji, and introduced:

"Mr. Xin, this is manganese ore."

As soon as Xin Qiji took the stone, he felt that the stone was heavy, most of the stone was black, with a faint luster, but there were also light-colored parts in the stone, Xin Qiji dealt with ores every day these days, and naturally knew that all ores were not pure, limited by grade, and contained impurities in different ways. Those black stones with a faint luster looked very distinctive, and Xin Qiji thought that this was manganese ore, so he asked:

"On this stone, the black one is manganese ore, right?"

"Not bad! As Mr. Xin said, the black one is manganese ore, but if you look at this piece of ore, there are some differences. The two pieces of manganese ore came from Taiwan, and according to Mr. Mao, the manganese ore there in Tanzhou should be of higher grade. Mr. Mao also said that there are many varieties of manganese ore, as long as you grasp the three characteristics, black, hard, heavy, eighty percent is manganese ore. ”

Speaking of finding manganese ore from Taiwan, it was really a coincidence, it was originally a clue to collect coal from the aborigines, and the aborigines saw that the people of the Great Song Dynasty wanted to buy black stones, so all the stones with black were sent over, and the result was that by mistake, the manganese ore was also sent over.

The manganese ore brought to Xin Qiji is like this, Mao Geng was not sure if it was manganese ore at first, after all, Mao Geng had never touched manganese ore in his previous life, but Mao Geng had heard of a legend of manganese ore mining in the Republic of China, and it was precisely because of this legend that Mao Geng knew that the black stone might be manganese ore.

It is said that in 1912, when a villager surnamed Xie in Xiangtan was working in the Pingxiang Coal Mining Bureau, he told Lu Hongchang, the general transportation office of the bureau, that there was a black stone in the mountains of their village, and the villagers thought that it might be "iron ore". Lu Hongchang is a layman, but he is interested in this news. Coincidentally, in the second year, Lu Hongchang's son Lu Zhixue served in the Mining Department of the Hunan Provincial Department of Finance. The Lu family learned that Japan had a strong demand for manganese ore, so they invited Xiong Bingsan, Li Yiqin and others to raise funds to establish Yufu Mining Company, and was the first to mine manganese ore in Xiangtan, but there was almost no demand for manganese ore in China at that time, so all the mined stones were sold to Japan.

By 1917, local manganese ore mining began to take shape, with a daily output of more than 100 tons of manganese ore and a maximum annual output of 30,000 tons. The initial mining of manganese ore is all high-grade ore, the ore grade is more than 45%, but the high-yield and high-quality manganese ore does not contribute much to China's iron and steel industry, but has made an indelible contribution to the Japanese iron and steel industry, because most of the manganese ore is exported to Japan's Yawata Iron Works, from 1916 to 1927 12 years, the average of manganese ore sold to Yawata Iron Works every month is not less than 1,000 tons.

Xiangtan manganese ore provides a large number of high-quality manganese ore for the Japanese, which makes people feel very breathless when they think about it, there is nothing more cowardly than this! Damn, Japan lacks manganese ore resources, but the people of the Republic of China generously provide them with the best quality manganese oxide ore, it is no exaggeration to say that Japan's military industry exhibition during that period has the credit of Xiangtan manganese ore. Come to think of it, what is going on!

The suspected manganese ore sent by the natives was finally confirmed to be really manganese ore, Mao Geng smelted the manganese ferroalloy with the experimental blast furnace, and further obtained the manganese steel, and the natives beat it crookedly, which made Mao Geng feel that Taiwan is really worthy of the name of the treasure island.

Magnetite also appeared here, later generations only heard that all the iron ore used in Taiwan's steelmaking was imported, and it was impossible to imagine that Taiwan not only had magnetite but also manganese ore, and thought that these valuable resources were used by the Japanese for steelmaking during the Japanese occupation. It is conceivable that Japan occupied Taiwan for 50 years from 1895 to 1945, during which Taiwan's iron ore and manganese ore must have been consumed by the Japanese.

So, Mao Geng further thought of Xiangtan, known as the "manganese capital", since we Mao Geng arrived in the Song Dynasty, the tragedy of Xiangtan's high-quality manganese ore sold to the Japanese would never be staged. In any case, the manganese ore there must be mined for its own use, so in the plan of Minmetals, the long-term development of Xiangtan manganese mine is included in the sub-project.

In this era, Xiangtan and Changsha both belonged to Tanzhou. Mao Geng believes that if he finds Xin Qiji, who has been the prefect of Tanzhou, and the intervention of the Xiang army in Tanzhou, as long as the people of Tanzhou are moved slightly, it will not be difficult to find Xiangtan manganese mine. According to Mao Geng's plan, after the mining and smelting of Yongping copper ore are on the right track, once Xin Qijian has his hands freed, he can open Xiangtan manganese mine.

However, the shape of the exhibition was a bit unexpected, the plan was not as good as the change, and the 20,000 troops allocated by the imperial court to Minmetals Holdings showed a surplus at the beginning, so Fu Ziyun proposed the manganese ore project in advance.

Xin Qiji finished reading the manganese ore, and since Fu Ziyun was such a treasure, this manganese ore must have a good use, so he immediately asked:

"This manganese ore should be used to smelt manganese, but I don't know what is wonderful about manganese?"

As for the use of zinc, Xin Qiji probably knows a little, and now there is a manganese, I don't know how it will be compared to zinc.

Fu Ziyun took out something that looked like a piece of pig iron with his left hand, and picked up a spiral-shaped iron wire and two small iron balls with his right hand, and introduced:

"My left hand is manganese iron smelting obtained from manganese ore, Mr. Mao called manganese iron alloy, the spring and small steel ball in my right hand, which are mixed with manganese iron alloy, after being mixed with manganese iron alloy, the elasticity is better, the hardness is higher, and the wear resistance is also higher.

"Can't you make manganese?"

According to Mr. Mao, manganese can be refined, but it is quite difficult. And manganese itself is not very useful, it has to be added to iron to have a significant effect. ”

As Fu Ziyun introduced, in fact, the use of pure manganese is lackluster, but manganese is an indispensable component of alloy steel. Manganese doped in steel can improve strength, hardness and wear resistance, bearing steel, spring steel, tool steel, wear-resistant steel, heat-resistant steel, are inseparable from manganese, the track of the tank is manganese steel, and the steel type used to manufacture bearings and springs is also manganese alloy steel. Even high-quality carbon structural steel generally contains manganese o.7%~1.2%.

In the steel industry of later generations, it is almost unimaginable that there is no manganese, nickel and chromium are also important, but the importance of manganese is obviously above nickel and chromium, there can be no nickel and chromium, but there must be manganese.

It is a bit difficult to smelt pure manganese, but it is possible to smelt ferromanganese with a blast furnace - not to smelt manganese metal but to smelt manganese ferroalloy.

As long as there is an manganese iron alloy, adding a manganese iron alloy when smelting steel, you can get manganese alloy steel for different purposes.

Xin Qiji took the spring and the small steel ball handed over by Fu Ziyun, and tried the thing called the spring, the elasticity is indeed good, as for the small steel ball, he couldn't appreciate the beauty of the steel ball for a while.

Xin Qiji is a little lost, this manganese is obviously not as magical as zinc, why does Mao Geng want to name it "manganese"! Xin Qiji felt a trace of doubt at this time, and said:

"This thing is almost like iron, it doesn't seem to be as good as iron, why is it called 'manganese'! It's a little confusing. ”

At this time, Fugui couldn't help but interject:

"At the beginning, Mr. 6, Brother Fu's teacher, also had such a question, Brother Fu must still remember Mr. Mao's answer!"

"Of course I do."

Fu Ziyun then respectfully said to Xin Qiji:

On that day, Mr. Mao said that iron and manganese are like Confucianism and Mengxue in Confucianism, Confucius is the root and bone, Mengxue is the flesh and muscle, and Mengxue cannot be separated from Confucius and called Confucianism independently. Iron and manganese are the same, iron is the root bone, manganese is the muscle, manganese cannot be separated from iron, but with manganese in iron, it complements each other. ”

Oh, I see, Dare Tie is the protagonist, but Manganese is the best supporting role to add color, Kong Meng, Kong Meng, Meng, Meng's roles are indeed similar.

"Hehe, that's a good point!"

Yuan Fu kept thinking about it, and then he also interjected:

"The boy heard that the medicine is divided by the monarch and the minister, and this metallurgical method also has something in common! Copper with tin to get bronze, or zinc with brass. Iron is made with manganese, but what is gained? ”

"Gotta alloy steel! Let me tell you, this is what Mr. Mao said. Mr. Mao said that if you refine manganese-iron alloy, you can make treasure knives and swords, and you can also make many powerful weapons, in short, you must not underestimate manganese. Mr. Mao also said that the price of manganese ferroalloy can be sold for two or three times that of iron! ”

In fact, neither Fu Ziyun nor Fugui said that manganese ferroalloy is actually an important auxiliary material for steelmaking, which can be used for desulfurization and slag making. However, such a supplement from Fugui is enough to make Xin Qiji understand the importance of manganese.

Xin Qiji has always been resolute in doing things, and without hesitation at the moment, he sent his clan brother Xin Zhu and Fu Ziyun together, brought two craftsmen who were familiar with ironmaking, and immediately set off for Jinghu South Road, so that the Xiang army transferred to Yongping from Tanzhou would leave 1,000 people to find ore on the spot and try to refine ferromanganese.

The exhibition of the situation here of Minmetals Holdings is a bit unexpected by Mao Geng, the news of Minmetals Holdings' early entry into Xiangtan manganese mine has been transferred by Wenyuan, and the flying pigeon has been passed to Mao Geng here, in this regard, Mao Geng is very excited, with the cooperation of Minmetals Holdings, the steel industry of the Great Song Dynasty is expected to enter the era of alloy steel in advance.

Here in Taiwan, magnetite and manganese ore have been collected, but given that these ores are still in the hands of the aborigines, the ore supply is not enough to support the batch of ironmaking and steelmaking due to the limited mining capacity and transportation of the aborigines.

So far, Mao Geng has only built three small blast furnaces, and after some attempts, has smelted ferromanganese and high-quality pig iron, and on this basis, the first furnace of high manganese steel in this era has been smelted. Later, after some exploration, Mao Geng got spring steel. As for the bearing steel, high manganese steel was directly used as a bearing steel by Mao Geng, after the success of the plain plain bearing, the sample of the rolling bearing has also come out, and it is only a matter of time before it is put into practical use.
