Hanjing, western suburbs, ironware workshop.

At the foot of the hill facing the ten blast furnaces, all the way to the entrance, a layer of floating earth of nearly a foot had been dug up from two days ago.

Later, the laborers began to pour water on the ground and began to ram the earth with stone piers.

This is not the end, after ramming the earth, the bluestone of an inch size was brought from the foot of the mountain not far away, paved on the ground, and crushed with stones.

Then, hundreds of truckloads of ash and river sand pulled from the southern suburbs were dumped on the ground by truckloads and began to be stirred with water.

At this time, a red chariot was dragged over by two tall horses, and everyone in the iron shop knew that it was the chariot of the daughter of the chief Pei Jia.

When it came to this, all the blacksmiths were envious, and everyone wanted to have a daughter who could be favored by the prince, and this time it was a big success.

Because Pei Jia has foreign blood, he has always been able to engage in the lowest craftsman work, but he gave birth to a good daughter and suddenly became the chief of the iron workshop with thousands of people.

Many blacksmiths will not admit that Pei Jia is valued for sacrificing an iron sword.

Because no matter how good the technology is, it is only a craftsman.

But what about Pei Jia? Whether it was the chief of the chamberlain sent by the prince, or the chief of the Ministry of Industry of the Imperial Court, or even the soldiers of the Ministry of War, they did not dare to be arrogant and courteous in front of him.

Is this a treatment that can be enjoyed with craftsmanship?

Pei Ge'an jumped out of the carriage, and Lian Kun, the head of the ironsmith workshop, hurriedly greeted him with a smile. "The eldest sister is here, there are ashes everywhere here, it is better to sit in the tea house for a while."

Pei Gean waved his hand. "No time, is this cement and sand in proportion?"

Lian Kun didn't care at all, and said with a smile: "In strict accordance with the standards on the booklet, one truck of cement and four cars of sand." ”

Forty or fifty craftsmen counted in a sand pile according to five people, one person added water, and three people stirred.

These piles of sand are piled up on the side of the road, lined up, and when they are mixed, they can be laid directly on the road.

Nearby, dozens of laborers with wooden tools in their hands were waiting aside.

Most of them held in their hands a round wooden rod with a transverse handle on it, and at the lower end half a foot from the end there was a rectangular transverse board.

When the cement and sand are mixed well, the mortar is shoveled onto the bluestone by a wooden shovel. On both sides of the road there are wooden planks that enclose a road about five meters wide.

The mortar was shoveled into the road, and the laborers with wooden drills began to pound into the mud.

Lian Kun shouted loudly: "Work harder, don't be lazy, you have to pound the mud next to each other, and you can't let bubbles be left inside." ”

These laborers tinkered in front, and the laborers who followed behind smoothed the road with a plank of twine and a piece of wood.

Behind them were a group of masons with iron ladles in their hands, cushioned with a long wooden plank, and smoothing the road like a mirror.

Ludosun was itchy and poked his finger, and then his finger sank in.

He looked up at Peg'an. "Eldest sister, can this really become hard?"

Pei Ge'an smiled: "Think about what these gray powders are made of? It's a stone, but when it dries, it becomes as hard as a stone. ”

"If that's the case, it's really a great weapon to win the country."

Pei Ge'an looked down at the mud, then ran it with his hand again, and frowned.

Then, she raised her head and beckoned to Lian Kun, who hurriedly trotted over like a dog. "Big sister."

"The next pile of sediment is in the ratio of one car to three and a half cars, and then it is reversed for a while. Send two people to be anxious about the changes in each time period, and record them once an hour. ”

"Okay, I'll arrange it right away."

After Lian Kun retreated, Lu Duoxun immediately took out the paper and pencil in his arms and asked, "Eldest sister, is there a mistake?" ”

"No, it's just that today's cement labels are not enough, and the bonding strength is not strong, so we should add a little more cement."

Lu Duosun wrote down the cement label and the degree of cohesion that he didn't understand.

It's not good to ask too many questions at this time, and when Sister Pei, the little teacher, is in class, she will be able to ask these questions.

Seeing this scene, Pei Gean had a better impression of Lu Duoson. In her eyes, this is a practical official.

"We don't care about the composition of cement and sand, we just need to know how much cement and sand are used in the construction of roads, and the proportions of painting walls, building embankments, building houses, and building bridges are all different.

Even more finely divided, the proportions of the first and second layers of the painted wall are different. By mastering these proportions, you can build a strong house, a strong road. ”

Lu Duosun nodded and asked, "So, when will this road surface be dry?" ”

"This depends on the weather, basically it will not be more than two days, pay attention to one point, when the weather is hot, when it is about to dry, the top should be covered with a straw mat, and then drenched to prevent the sun from being too fierce, the top is dry, and the bottom is not dry, causing cracks."

Lu Duosun wrote it down again and asked, "Then what is the reason for separating a gap with a wooden strip every other paragraph?" ”

"This is the principle of thermal expansion and cold contraction, just like water will freeze in winter, the road surface will become larger when the weather is hot, and it will shrink when the weather is cold, if there is no gap, when the weather is hot, the road surface will squeeze each other, which will cause cracks and bulge."

When Pei Ge'an saw his second brother coming over, he didn't care about him anymore, and walked over with a smile.

Lu Duosun didn't bother, wrote it down, and then figured out the reasoning.

These days of contact, following the learning, he realized that he had come into contact with a wide world.

Before he got closer, Pei Yun took out a dagger with a fish scale pattern from his arms, although he knew that he was Sister Pei's brother, Xu Yongchang and several guards hurriedly walked in front of Sister Pei.

Xu Yongchang said with a smile: "Second Brother Pei, this is a dagger made for the eldest sister?" Let me pass it on to my eldest sister......"

Pei Yun was a little embarrassed, glanced at Pei Ge'an, who was smiling, handed the dagger to Xu Yongchang, and touched his head.

Pei Ge'an took the dagger, danced in his hand, and said with a smile: "Second brother, I like it." ”

Pei Yun laughed. "If you like it, Dad asked me to tell you, the hydraulic grinder is almost there, let you go over and see if you want to change it."

Pei Ge'an turned his head and said to Xu Yongchang: "Send someone to the grinding wheel factory and ask if the grinding wheel in the iron sand has solidified, and if it solidifies, send one piece of each one to the grinding machine workshop." ”

Xu Yongchang gave the order, and Pei Ge'an walked to the carriage. "Second brother, come here, let's talk."

Pei Yun smiled and followed, this chariot is regulated by the Prince's Mansion, with four wheels, like a small house on it, where a circle of people can sit in front, and there is a toilet room in the back.

Pei Yun didn't dare to sit in, so he sat on the wheel and talked to the girl through the open window.

In an accident last summer, the eldest sister became a different person, and she was accepted into the mansion by the prince.

The Pei family has developed so far, first lived in the prince's farm, and then came to Hanjing, where they managed this ironcraft workshop with thousands of people.

From last autumn and winter to the present, the ironware workshop has built two charcoal kilns, two fireproof brick kilns, and ten new iron kilns.

This workshop does not make iron, it all transports pig iron from Nanyang, and makes steel directly here.

There are five hundred blacksmiths alone, and five thousand with apprentices and servants.

There are still a few kilns that have not been lit, and if they are all lit, 10,000 people will not be able to stop them.

The Pei family has divided the largest courtyard in the artisan camp at the foot of Wanshan Mountain, and their monthly income is higher than the income of the past year.

Also because of the relationship between the eldest sister, my father became the director, although he was only in charge of technology, but everyone was very polite to them.

In the past, a non-qualified errand officer could shout at their father and son, but now the four or five rank outsiders are holding them.

This is all the glory brought by the eldest sister!

The car drove along the road in the ironworks and came directly to the river.

Here, the embankment along the river was rebuilt, not only widened and heightened, but also built a platform several miles long on the embankment and here along the river.

At intervals on the platform, there is a wooden trestle that goes deep into the river. Today, more than a dozen waterwheels have been erected.

Under the protection of several guards, Pei Ge'an came to the front of a row of blue-brick houses, and an iron rod protruding from the river was spinning rapidly, leading to the house.

One end of the iron rod is connected to the waterwheel, and the other end is directly connected to a wooden platform.

Nowadays, there is no standard lathe, grinder, everything is simple. Rely on these simple devices to create standard accessories before you can assemble a real machine.

With standard machines, products can be standardized and scaled.

Pei Jia and several officials were discussing something around the grinder, and when they saw Pei Ge'an coming, they saluted one after another.

Even if he looked down on her, he didn't dare to look down on Xu Yongchang and the guards of the forbidden army behind her.

Pei Ge'an leaned over to the grinder and looked around, shaking his head again and again.

Now the bearing has not been built, and the fixation can only rely on the copper ring, and then the fittings are seriously worn, shaky, and the precision is very poor.

The round grinding wheel taken from the grinding wheel factory was mounted on it, and the standard round grinding wheel swayed more than two millimeters when it rotated.

Such a grinding machine requires the technician to rely on experience to polish the accessories.

The technician brought over a drive rod, which was made by boiling molten steel until it was half-melted and then die-cast, with a row of burrs on it.

Approaching the grinding wheel, there was a screeching grinding sound and a spark in front of it.

Although it shook badly, the technician quickly polished the drive rod smoothly after mastering the law of shaking.

Everyone in the circle laughed, and finally lived up to the holy order.

"Daddy, the lathe and grinder are temporarily put on hold, don't add any more, such an improvement does not reflect the advanced waterwheel linkage at all. The accessories are first polished by craftsmen, and the machine is assembled first. Wait for the second brother ......"

Pei Ge'an looked at his second brother and changed his words: "When I have time to stay behind, come and guide you." ”

This kind of transition from the most basic manual to machine tools, Pei Ge'an does not understand, she only knows that this efficiency has not improved much, but the cost is greater than in the past.

Since Zhao Dezhao understands, let him give advice.
