"This iron, like steel, is easier to use than iron."

"Sir, this iron is like the iron tool of the former Han Dynasty dug out in Chang'an in the fifteenth year of Zhenguan."

"If it is used as a pipe, it will definitely be good."

During the routine inspection of Jiangxia Steel Plant, the factory leaders and technical backbones accompanied them all expressed their efforts to achieve better results in the upper reaches. But Lao Zhang did not intend to chat with them this time, but a student opened a small idea in the branch of Yongxing Coal Mine, and then... and then made a subtle thing.

"Goro."

"Students are here."

"We're talking as we go."

"yes."

Xiong Quehuo was originally called Xiong Chuwu, and his family was in the fifth place. He had four elder brothers. There were only one legitimate brother, and the other few were cousins. The family was originally a mountain villager, with about 600 acres of mountain land and no water. His mother was from Liaozhai. His life was not too bad before, after all, there were even worse than them.

By chance, his mother from the Liaozhai actually sent his son, who was just about age to the Mianzhou "Technical School".

In Jianghan, there are very few women from the Liaozhai who have such a spirit and ideas.

But Xiong Chuwu graduated successfully, passed the assessment of Jiangxia Steel Plant, and became a technician of the Steel Plant.

“Are there any experimental reports?”

"Sir, there are."

Now Xiong Chuwu, named Xiong Quinhu, handed Zhang De the experimental report of black paint and black. After Lao Zhang scanned it, he knew what kind of imagination this guy had.

"You added 'flint'?"

"It's not an ordinary 'flint', it must be a Nanchang product. Shandong 'flint' is not good. According to students, there must be differences in the 'flint' components. However, the methods are limited at present and cannot be detected."

"First archive, continue to try, and then set up Nanchang's 'flint' to see where it was produced, and then buy that mine."

"Yes, sir."

The students opened their brains, and ductile iron was born.

Although the indicators must be a mess, this thing is easy to use.

As for the output, it must be only related to the scale of the blast furnace and the "flint" in Nanchang. Lao Zhang could probably estimate what the "flint" in Nanchang is, and even where the origin is, but after all, it is difficult to deal with "iron" involved. It is always necessary to put two or three vests in exchange for a few different projects.

Maybe we have to get a Jiangxia Pipe Factory out, and the purpose is this ductile iron.

Although Lao Zhang was very happy, he was not so happy that he could not control himself. In the seventeenth year of Zhenguan, it is enough to not have too bad quality of pig iron.

Generally, the armor leaves of elite troops are more than enough to make iron sheets. How many of the barbarians around can break the defense? According to the best quality Indian steel on the Silk Road, the output of this thing depends entirely on God, and it only has technical significance.

Because the annual output of the Tumen, the northern Indian country that can produce this steel is only about 500 kilograms. The steel ingots produced in one batch are about 2 kilograms of balls, and most of them were originally exported to Persia. When Changsun Chong was in the river, he named this steel Damascus steel because his fellow traveler Sura believed that this was seen in Damascus.

In fact, the origin of these steel materials is east of Persia.

After the Silk Road reopened, with the Bolu Pass as a passage, Tianzhu Steel can enter the south of the Bolu Pass from the Bolu Pass, and then exit the Yangguan, and trade in Dunhuang.

The Dunhuang Palace Palace Supervisor was for the emperor, and basically all the hundreds of kilograms of Tianzhu steel exported to the Tang Dynasty were eaten.

In the seventeenth year of Zhenguan, Li Shimin had digested many steel ingots. What's more, not to mention that there were not many.

At present, the steel produced by Shicheng Steel Plant is basically the same as this crucible steelmaking method. The output is low, mainly to maintain the elite royal troops of the Central Army. To put it bluntly, it is the Yulin Army, and now it needs to add a tax collection...

Only the Western Army and the Northern Army can be equipped with some of the border troops, but most of them still sing "Iron Armor is Still There", even "Leather Armor is Still There", and "Cloth Armor is Still There", and a small number of them "No Armor is Still There"...

A huge number of troops, everyone with armor, can kill the world with your eyes closed.

The main idea that students have created is that workpiece casting is more reliable, and a small "industrial upgrade" in Wuhan can still be achieved. It can replace too many workpieces that can be used to replace wood, stone, copper and iron. In terms of cost, it is how to make Nanchang "flint" cheaper.

As for freight and shipping, can it be called freight?

Lao Zhang didn't need to judge whether it was really graphite spherical. As long as the processing and casting indicators were improved, it could be continued. At this time, it was not him who was deeply grasping the indicators.

"Is this 'new iron' useful?"

"In comparison, it must be easy to use and can save a lot of bronze parts, such as bearings... Uh, where is Xue Niang?"

When Lao Zhang saw Madam Cui's dull expression, he knew that this was nonsense. After finding an excuse, he went to play with his daughter.

Because the weather is hot, Lao Zhang is willing to travel to Linzhang Mountain as long as he has time or gets off work. Not to mention the shade in the mountains, another courtyard has also built a swimming pool, which attracts mountain spring water. It is so cool to swim and cool down.

Seeing Annu taking Zhang Luoshui to fight under the eaves of the swimming pool, Zhang De smiled and turned to the study. It’s not that he doesn’t want to play in the water together, but because he really needs too much business backlog, he has to hurry up and approve it.

In addition to the administrative business in Wuhan, China Resources, fleets, and Western Regions communication... the backlog of problems requires him to judge the decisions, and the number is hundreds or thousands. This is the business volume generated by him having a large number of accounting teams and staff teams.

In comparison, Lao Zhang really thinks that Mr. Li is a natural workaholic.

"Oh? He actually gained a firm foothold in Yazhou?"

The "military" fleet has stabilized the route of "Qianli Shitang", spices, masterbatches, minerals, seafood... This is a route with great profits, but the expedition team will not be satisfied. The sailors who have replaced the fleet one after another often want to win a wealth of three generations.

Even in the fifteenth year of Zhenguan, Wang Wansui had a boat under his command, and he actually "defected" Fusang, then "sieged cities and territory", and actually established himself as a "country".

After two fights, after the "destroyment of the country", although most of the "traitors" were fed fish by Shenhai, many people still fled to the northeast of Fusang, mingled with the "savages" and became the "local king".

This matter was very big for Wang Wansui, but for Zhang De, it was simply common. Even in Guanzhong, black households suddenly appeared from time to time, with dozens of people calling themselves generals or kings, entrenched all over the place, waiting for the government to wipe out.

It was just that the problem was in the fleet, which made Wang Wansui, who was famous, feel a little ashamed.

"Gold mine? Another gold mine?"

Zhang De was stunned. The "militia" fleet sent several messages back in Yazhou, Danzhou and Guangzhou, one month ago. The news said that it was south of the Brahman country, crossing mountains and ridges, and then seeing the sea.

“Um…”

After spreading the map and comparing what the "militaries" called Brahmani, Zhang De determined that this was "Brunei". "Brunei" itself has gold mines, but obviously what the "militaries" were talking about the gold mines here.

"They didn't sail to the south of the island, but walked through land after landing? What's this? The Marine Corps' practice?"

After a little complaint, Old Zhang thought about it again, "It seems that he wants to stay. The gold mine here must be of a large scale and has a good quality."
