Steel is worthy of being an important indicator to measure the level of modern industry, and it also makes a sentence of the ancient Chinese people, in the process of manufacturing manganese steel, vividly embodied, 'If you want to do a good job, you must first sharpen your tools'. "Co*music*words*love*first*hair(http://www.klxsw.com

Manganese steel is now manufactured, and after that, many industrial components are no longer afraid.

As mentioned earlier, the firing of the crucible model is mainly for the production of precision instruments, but the current weights and measures of the Ming Dynasty are somewhat non-standardized.

A point, a thread, a millimeter, a centimeter, an inch, a foot, a zhang, and so on, but these sizes, who is honest, there is no specific comparison, therefore, a lot of it is just people's experience.

In terms of weight, the Ming Dynasty was sixteen taels for one catty, and two catties were thirty-two taels, which was very inconvenient, and one stone was one hundred and twenty catties, with a fraction.

There are both decimal and hexadecimal systems, and many things are relatively vague, which is a fatal blow in modern precision industrial manufacturing.

Zhu Changhao couldn't think of a better way, so he had to borrow ready-made weights and measures from the 21st century.

Everything is in decimal units, i.e. the units of length are meters, decimeters, centimeters, millimeters, and silk meters.

The weight units are tons, kilograms, taels, grams, etc

The volume units are cubic millimeters, cubic centimeters, cubic decimeters, cubic meters, cubic meters, etc.

Although Zhu Changhao knows these dimensions, it is not clear how to compare them.

However, this was not a problem, because he remembered that one meter was equal to three three three three feet.

In this way, from the inside of the ordnance prison, there are special craftsmen to build.

The unit of weight is also easy to calculate, sixteen taels is about 700 grams, and if you change 700 grams to 500 grams, then it won't be a catty?

In terms of volume, one cubic meter of water is equal to two thousand catties, that is, one meal, and so on, you can also know other weight units.

Zhu Changhao pondered for a while, wrote down his thoughts in a notebook, and went to the Ordnance Prison tomorrow to make a meter ruler with silver, and the length unit of the Ming Dynasty in the future will be based on this meter ruler.

In the future, Zhu Changhao decided to collect this ruler himself.

This is the question of weights and measures, and after thinking about it for a while, I will give the emperor a fold, about the Ming Dynasty Liaodong Xuanzhi and the canonization of the seven imperial universities.

In the compromise, for the Liaodong Propaganda Envoy, Zhu Changhao also asked his nephew Emperor to send a eunuch to supervise his Liaodong Propaganda Envoy's request, so as to lower Chongzhen's vigilance against himself.

In the second letter, Zhu Changhao also set up Xiangyang Huitongyu City this summer, and the 10,000 taels of silver collected in the summer tax will be escorted to Beijing.

In the third letter, Zhu Changhao used the excuse of transporting rice from western Guangdong to the south, and demanded the formation of the Dongting Lake Water Division, the Poyang Lake Water Division, as well as the Beiyang Water Division to defend the Japanese State, and the Nanyang Water Division to defend the southwest sea frontier.

These sailors, Zhu Changhao wrote in the excerpt, five to ten years later, if the emperor needs, they can be returned to the imperial court, the most important thing is that the silver taels, ordnance, and warships that formed these sailors were provided by Zhu Changhao, the king of Rui, alone.

There are three things in total, and three points are written, which are the seven royal universities, the Liaodong Propaganda Envoy, and the Sailor Division.

After Zhu Changhao finished writing these three books, he vaguely felt in his heart that he seemed to have forgotten his opinions, but he really couldn't remember what it was.

slept very comfortably at night, and slept with Liu Zilian, without saying a word.

(This chapter is not finished, please turn the page) The blazing sun in the morning light is still so dazzling, Zhu Changhao did not go to the ordnance supervision today, because today I want to see what is the case with the manganese steel rolls (steel columns), whether they meet the requirements of the coiling press and the rolling mill.

If it is reached, then the hydraulically driven rolling mill can be completed, and then the steam mechanism is zuò, then it is also promising.

Moreover, for ironclad ships, artillery, and silver dollars, it is not a coinage, but a pressure on money.

But in the morning, Zhu Changhao did not sit and wait, wasted, in the garden, after more than an hour of vomiting, gestures and other methods, Zhu Changhao finally finished today's "Yellow Emperor Neijing" course.

Refreshed, after eating breakfast, I went to the school in the palace to see how Mr. taught.

Zhu Changhao was on the circle wall next to the school hall and heard that the children were reading "Thousand Character Text", and he felt a little relieved inexplicably.

Moreover, the tone of the lecture is very pleasant, and there is a natural beauty.

Zhu Changhao listened for a while, and felt that it was not bad, so he planned to go through the back door to see the work of the three provinces and six departments in the political affairs hall.

Sun Chengzong, who saw Zhongshu Province and the military department, was reading a report from the Inspection Division.

After Zhu Changhao entered, after a hall official brought two cups of tea to himself and Sun Chengzong, Sun Chengzong said, "Lord Wang, now the taxes transported by the inspection departments of various parts of the Han River have been put into the warehouse, but their food and salary for this autumn have not been allocated. ”

"Oh, how much is this summer tax revenue?"

"Back to the prince, there are millions of taels in total, but this summer, because Xiangyang Huitongyu City wants to supply two water divisions, their income has not been handed over, but the account books have been sent, mainly the accounts of the Financial Bureau, the Commerce Bureau, and the Taxation Bureau."

"Well, come down to this king and have a look."

"Old marshal, is there a record of the Military Discipline Department?"

"Oh, if you don't mention it, the old man almost forgot, this is the record of the Military Discipline Department, please take a look."

Zhu Changhao probably looked through it and found that it was not bad, judging from the records of the three kinds of tables and the Military Discipline Department, Xiangyang's summer tax revenue was very objective, no less than one million taels of silver.

"The 3,000-mile Han River, as long as there are a little conditions suitable for commercial development, it can create no less than 10 million taels of tax revenue, but unfortunately above the Ming Dynasty, because commerce is controlled by scholars, the country's taxes can only come from the peasants, which leads to the exhaustion of the Ming Dynasty's financial resources," Zhu Changhao sighed secretly in his heart.

However, the food and salary matter has not yet been done, and the inspection departments in various places want the autumn salary, so the palace must allocate it, and it must be distributed in full.

In this way, Zhu Changhao said to Sun Chengzong, "Old Shuai, you are now the Zhongshu Order of Zhongshu Province, or the squire of the Ministry of War, and the matter of allocating food and salary will be handed over to you."

In this way, you will register the food and salary required by the inspection department in various places, in triplicate, one for the military department, one for the household department, and one for the province of Shangshu for archiving. When the time comes, this king Zhu will approve and allocate it, okay? ”

"It's still thoughtful that the prince thinks about it, and the old minister will let the court officials and the pen make a table to register, and then let the transport fleet of the palace set off immediately," Sun Chengzong said with great interest.

"Okay, but the old handsome, whoever makes that part of the watch, who has to sign and draw, will be responsible for the watch he made in the future, if there is a mistake, the king will check it layer by layer, whoever has a problem, he will deal with whom, please make it clear to the court officials and the pen posts when the old man makes the watch."

(This chapter is not finished, please turn the page) "Yes, lord, the old minister understands. ”

"Well, that's good, you're busy, this king will go out for a walk again"

"Congratulations to the prince"

Zhu Changhao was next in the front hall and saw that in these six parts, only the servants of the Ministry Qu Shiyun and the pen posts were scribbling and painting. When Zhu Changhao saw this scene, in the spirit of reducing trouble, he did not go in, but left.

After looking around, I saw that the hour was already noon, and the sun at the beginning of August was still a little hot, and I heard it screaming again, but the sound became a little miserable, probably because of the feeling of 'chilling cicadas'.

As soon as he entered the palace, he heard Wang Huaizhen say with a duck's voice, "Hurry up, go and find the prince, and say that the weapons supervisor has arrived." ”

When Zhu Changhao heard this, he said loudly, "Don't look for it, this king is back." ”

After three or two steps into the front yard, Zhu Changhao saw a carriage parked next to Sun Yuanhua and Song Yingxing, and Zhu Changhao said directly, "Two of you are exempt, the roll, that is, the steel shaft, is here?" ”

"Yes, Lord Wang", Sun Yuanhua said excitedly.

"Okay, let people take it down and take a look at this king", Zhu Changhao said excitedly.

As a result, the swarthy steel shaft was lifted down, Zhu Changhao saw it, and asked excitedly, "Two, have you tried it, and what is the effect?" ”

"Back to the prince, we tried, using a twelve-pound steel hammer to beat, and a good steel knife to chop and poke, but there was no mark, which shows that this steelmaking is successful."

"Oh, in this way, this thing made by the king is called a roll, and in the future, the iron sheet, iron plate, and steel plate, including the zuò of the silver dollar at the back, will be inseparable from this roll.

The principle of this thing is the same as our rolling pin, if you go back and put two rolling pins together, leave a gap in the middle, press the gnocchi on it, and then turn the rolling pin, you can get noodles, which is soup cakes and stuff like that. ”

"Really, Lord Wang?" Song Yingxing said in surprise.

"Really, this dough pressing process is actually using this roll to press the steel plate, and the process of the iron plate is similar."

"Thank you for your guidance", Sun Yuanhua and Song Yingxing, who were surprised, said with their fists cupped.

"Hey, this is just the experience of this king", Zhu Changhao deliberately said with a pretending smile.

"Lord Wang, you see that it's already noon now, so we won't bother you, and we'll go back to the weapons prison."

"Don't go back, you two are having a family banquet in the palace today, and this king also wants to entertain the two."

When Sun Yuanhua and Song Yingxing heard the prince say this, they glanced at each other and said, "Lord Wang, then I might as well be respectful." ”

"Haha, two, let's hold a banquet in the Purple Air Pavilion today, Uncle Wang, you let Sun Laoshuai and Qu Shiyun also be invited, the others are too far away, this king will talk about it later."

Zhu Changhao took the two of them into the Purple Air Pavilion, and he was also pondering in his heart, "Since this manganese steel zuò has come out, the limestone here in Hanzhong is very rich, and this cement production should also be mentioned." Also, I don't know what happened to the transformation of the textile machine that Song Yingxing transformed? If the transformation of this thing is successful, then the light industry of the Ming Dynasty will be half of the success, in fact, this king also understands that with the manufacture of manganese steel rolls, the heavy industry system of the Ming Dynasty has finally been established. ”

Scholars really hope that in the last two days of 2015, readers will come to the show and increase their subscriptions. In this cold winter, let the scholars feel the warmth of spring! ）
