"This iron, like steel, works better than iron."

"Sir, this iron seems to be the iron of the former Han Dynasty dug up in Chang'an in the fifteenth year of Zhenguan."

"If it's used to make pipes, it must be good."

During the routine inspection of Jiangxia Iron and Steel Plant, the accompanying plant leaders and technical backbones expressed their desire to strive for new achievements in the upstream. But Lao Zhang came back this time, and he didn't plan to talk to them at all, but there was a student who opened a small brain hole in the branch of Yongxing Coal Mine, and then ...... Then make a subtle one.

"Goro."

"The students are here."

"We'll talk as we go."

"Yes."

Xiong Quenhuo was originally called Xiong Chuwu, and he had four brothers in the family. There is only one brother-in-law, and the other are cousins. The family was originally a mountain people, there were more than 600 acres of thin land in the mountains, there was no water to irrigate the land, his mother came from Fangzhai, and the early days could not be said to be too bad, after all, there were worse than them.

Due to fate, his mother who came out of Fangzhai actually sent his son, who was just the right age, to the "technical school" in Chuzhou.

In the entire Jianghan Dynasty, there are very few Fangzhai women who have such courage and ideas.

But in the end, Xiong Chuwu successfully completed his studies, successfully passed the assessment of Jiangxia Iron and Steel Plant, and became a technician in the Iron and Steel Plant.

"Do you have a lab report?"

"Yes, sir."

Now Xiong Chuwu, whose name is Xiong Quenching, handed the black experimental report to Zhang De, and after Lao Zhang swept it, he knew what kind of brain hole this product had opened.

"You added 'flint'?"

"It's not an ordinary 'flint', it has to be Nanchang goods. Shandong 'flint' is not good, depending on the students, there must be differences in the composition of this 'flint'. It's just that the means are limited at the moment, and it can't be detected yet. ”

"File it first, continue to try it later, and then set down the Nanchang 'flint' first, see where it is produced, and buy the mine when the time comes."

"Yes, sir."

The students opened their minds, and as a result, ductile iron was born.

It's a mess, but it's a good thing.

As for the output, it must only be related to the scale of the blast furnace and the Nanchang "flint". Lao Zhang can probably estimate what the "flint" in Nanchang is, and even where it is produced, but after all, when it comes to "iron", things are not easy to do. It is always necessary to set two or three vests for a few different items.

Maybe you have to get a Jiangxia pipeline factory out, and then the purpose is this nodular cast iron.

Although Lao Zhang is very happy, he is not so happy that he can't help himself, at the moment of Zhenguan for seventeen years, the quality of pig iron is not too bad, it is enough.

The armor leaves of the general elite troops, wrought iron pieces are more than enough, and how many barbarians around can break the defense? According to the best quality Tianzhu steel on the Silk Road, the output of this thing depends on God, and only has technical significance.

Because the Tu Bang of Beitianzhu that can produce this steel, the annual output is only about 500 catties. A batch of steel ingots, are about two catties of balls, most of the original were exported to Persia, when the eldest grandson Chong in the river, this kind of steel was named Damascus steel, because of the companion Sulla, thought that this was seen in Damascus.

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

After the reopening of the Silk Road, with the Bolu Pass as a passage, Tianzhu Steel can enter the south and end of the Moraine from the Bolu Pass, and then exit Yangguan, which can be traded in Dunhuang.

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

At the moment of Zhenguan's seventeenth year, Li Shimin has digested how many steel ingots. What's more, not much.

At present, the steel produced by Shicheng Iron and Steel Plant is basically this crucible steelmaking method, and the output is low, mainly to maintain the elite royal army equipment of the Central Army. To put it bluntly, it is the Yulin Army, and now there is a tax collector......

The border army can only be equipped with some of the Western Army and the Northern Army, but most of them still sing "The iron armor is still there", and even "The leather armor is still there", and "The cloth armor is still there", and a small part of "The armor is still there......

With a huge number of troops, everyone wearing armor, it is really possible to kill the world with their eyes closed.

The main reason for the student's brain hole is that the workpiece casting is more reliable, and the small "industrial upgrading" in Wuhan can still be done. It can replace too many wood, stone, copper and iron workpieces, and in terms of cost, it is how to make Nanchang "flint" cheaper.

As for the freight, the freight of the ship, can it be called the freight?

Whether it is really graphite spheroidal, Lao Zhang does not need to judge, as long as the processing and casting index is improved, it can be continued, and the person who grasps the index at this time is not him.

"Is this 'new iron' going to be easy to use?"

"In comparison, it must be easy to use, and it can save a lot of bronze parts, such as bearings...... Uh, what about the Snow Maiden? ”

Seeing Cui Niangzi's sluggish expression, Lao Zhang knew that saying this was nonsense, so he found an excuse and went to play with his daughter.

Because of the hot weather, as long as he is free or off work, Lao Zhang is willing to go to Linzhang Mountain. Not to mention the shade in the mountains, the courtyard also built a swimming pool, which leads to mountain spring water, swimming to reduce the heat, it is simply not too cool.

Under the eaves of the pool porch, he saw Anu taking Zhang Luoshui to have a water fight, Zhang De smiled, and turned around and went to the study, not that he didn't want to play in the water together, but there was too much backlog of business, so he had to hurry up and approve.

In addition to the administrative business in Wuhan, China Resources, the fleet, and the Western Regions communication ...... The backlog of problems, which require him to judge the clapper, are hundreds or thousands. This is still the amount of business generated when he already has a large accounting team and staff team.

In contrast, Lao Zhang really thinks that Li Dong is a natural workaholic.

"Oh? Actually gained a firm foothold in Yazhou? ”

The "militia" fleet has stabilized the route of the "Qianli Shitang", spices, masterbatches, minerals, and seafood...... This is a lucrative route, but the expedition team will not be satisfied, and the sailors who have been replaced by the fleet often want to fight for three generations of wealth.

Even in the fifteenth year of Zhenguan, Wang Wansui had a boat under his command, and he actually "defected" to Fusang, and then "conquered the city" and actually established "a country" on his own.

After fighting two battles before and after, after the "destruction of the country", although most of the "traitors" were fed fish in the sinking sea, many people still wandered to the northeast of Fuso, mixed with the "wild people", and became the "king of the soil".

This matter is very big for Wang Wansui, but for Zhang De, it is simply commonplace. Even in Guanzhong, from time to time, black households suddenly appeared, with dozens of people, calling themselves generals or kings, entrenched in one place, waiting for the government to exterminate them.

It's just that the problem was in the fleet, which made the famous Wang Wanzai a little ashamed.

"Gold mines? Another gold mine? ”

Zhang De was stunned for a moment, and the "militia" fleet sent several messages back in Yazhou, Danzhou, and Guangzhou one after another, and the time was a month ago. It is said that it is in the south of the country of Brahmanai, and when you go over the mountains and mountains, you can see the sea.

"Hmm......"

Spreading out the map and comparing it with the brahmani mentioned by the "militia", Zhang De determined that this was "Brunei", and "Brunei" itself had gold mines, but it was obvious that the "militiamen" were not talking about gold mines here.

"They didn't sail to the south of the island, but landed and traveled by land? What is this, the practice of the Marine Corps? ”

After spitting out a little, Lao Zhang pondered again, "It seems that I want to be stationed, then the gold mine here must be not small in scale, and the quality is not bad." ”
