After Luo Qing sorted out her emotions, she began to prepare for the affairs of the Daming Fire Weapons Bureau. Pen, fun, and www.biquge.info

She first went to the Ministry of Industry to get the official document approving the establishment of the Daming Firearms Bureau, and then began to look for a suitable address.

Luo Qing surveyed in the capital for several days, and finally selected a glass workshop located near Liuli Street in Nanshi.

Luo Qing found the owner of the workshop and discussed the purchase of the workshop.

The negotiation went smoothly, and in the end, Luo Qing won the glass workshop at a price of 10,000 taels of silver.

It covers an area of about four acres, which is neither too big nor too small.

There are several blast furnaces used to burn glazed raw materials in the site, and after Luo Qing took over the workshop, he hired people to dismantle them all.

Because what Luo Qing wants to refine is steel, the blast furnace needed to refine steel and the blast furnace needed to refine glass are completely different existences and cannot be used directly. So simply dismantle them all.

After demolishing several glazed blast furnaces, Luo Qing was not busy building steel blast furnaces, but first went to investigate the steel situation on the market.

After the investigation, Luo Qing found that the iron ingots sold on the market were not of high purity and could not meet the steel standards mentioned in the drawings.

To make carbon steel with high purity, it is necessary to purify the iron ingots available on the market, which requires the use of a special blast furnace.

The secrets of this blast furnace were in the hands of a few families, and the imperial court did not have such technology.

Luo Qing, who felt helpless, had no choice but to report the situation to Tang Mo.

Knowing that Luo Qing was worried about steelmaking, Tang Mo also attached great importance to it.

She began to recall the knowledge about steel refining in her previous life, which was the knowledge when she read a book in college by chance, Tang Mo originally thought that she had forgotten it, but after drinking the fairy water, her memory was greatly strengthened, and she clearly recalled all the contents of the book she had read at that time.

That book mainly talks about the changes in science and technology in history, and briefly mentions the different levels of science and technology in various eras by the way.

Among them is the knowledge of blast furnace steelmaking.

Tang Mo began to write down the information of the steelmaking blast furnace he had seen at that time according to his recollections.

After writing it, Tang Mo handed over the information to Luo Qing and told her that it was included in the palace treasury, and asked her not to pass it on.

Luo Qing was overjoyed, and her admiration for Tang Mo reached a new height.

He said yes and left the palace.

With the information on the steelmaking blast furnace, Luo Qing set out to gather the craftsmen.

A thousand Praetorian Guards have been sent to Luo Qing's side, ready to be used at any time.

Luo Qing arranged for two hundred Praetorian Guards to control the workshop, rotate the guards, and then began to recruit craftsmen.

This time, it was mainly blacksmiths and masons who were recruited to make special parts, masons who made molds, and masons who cast blast furnaces.

In order to attract more skilled craftsmen, Luo Qing offered a price of more than double the market price for the employment of craftsmen, but the requirement was that once he entered the workshop, he would cut off all contact with the outside world.

Next, Luo Qing began to redraw the drawings, and divided the four weapons in the drawings into different parts, in this process, she always encountered a lot of difficulties, fortunately, her current identity is a female official in the palace, and she can enter the palace at any time, so whenever she encounters difficulties, she enters the palace to ask Her Majesty the Empress for advice.

In Luo Qing's heart, the empress is not only the master of Daming, but also her best friend.

With Tang Mo's help, it took Luo Qing more than ten days to finally split the various parts on the four weapons and draw them on different drawings.

At this time, the recruitment of craftsmen has also come to an end, and a total of more than 100 craftsmen have been recruited, and they are about to enter the workshop.

Luo Qing advanced thirty taels of silver per person, and then gave each person a day to get the family chores done, and then let them all enter the workshop.

The door to the workshop was closed, and the only remaining side door was guarded by a team of Praetorian Guards.

In the workshop compound, Luo Qing began to arrange the first task of the craftsmen.

Construction of steel blast furnaces.

Luo Qing had drawings, she repainted many copies of the drawings, selected four old craftsmen, appointed them as team leaders, and then asked them to take four groups of craftsmen to be responsible for the construction of four blast furnaces.

Luo Qing personally supervised the construction quality of the four blast furnaces, and once he found something unsatisfactory, he immediately ordered it to be reworked.

The craftsmen are paid on a monthly basis, so they have to rework and rebuild without complaint.

Under the continuous rework and reconstruction, the progress of the four blast furnaces was slow, and because the error required to be smooth inside the blast furnace could not exceed one point, once the craftsmen were a little unfocused, they would get an error of more than one point.

The entire blast furnace was scrapped and had to be recast.

The inside of the blast furnace is a step-like structure that continues downward, and the iron ingots flow downward after melting, and the impurities in it are incinerated at high temperature in the process, and finally flow out from the discharge port, and then re-added to the blast furnace, and so on many times before the molten steel can finally be obtained.

These structures must have a very small error, otherwise the molten iron will be heated unevenly, the impurities will not be incinerated cleanly, and the molten steel that meets the requirements will not be produced at all.

Under Luo Qing's strict supervision, it took two months for the four clay blast furnaces to finally be completed.

However, this is only the first step.

After the blast furnace is completed, the craftsmen begin firing.

The blast furnace needs to be thoroughly cured before it can be used for final use.

In this process, there are many uncertain factors, which are very likely to cause imperfect firing, and the entire blast furnace will be scrapped.

Luo Qing's luck was not bad, seven days later, the firing was over, and two of the four blast furnaces could be used.

The other two blast furnaces were scrapped due to firing errors.

The two blast furnaces were enough for experimentation, and Luo Qing no longer asked the craftsmen to cast the blast furnaces, but began to let them make steel.

Commercially available iron ingots are heated and melted before being placed in a blast furnace to remove impurities.

After seven re-refining, the first pot of usable molten steel was refined.

The first thing Luo Qing was going to make was a pistol, which was the smallest, so it was the easiest to make.

After the molten steel cooled, Luo Qing began to have craftsmen make clay molds.

The clay mold is the basis for casting a pistol, and without a mold, then everything is a flower in the mirror, a moon in the water.

The casting mold was also very difficult, and it took a month to make the first pistol mold.

There are a total of 43 parts, and the molds have reached as many as 43.

Among them, the barrel casting mold method is Luo Qing's first creation, as long as the mold she makes is used, the barrel can be directly cast.

Pistol components include bolt components, transmitter components, magazine components, grip components, barrels, barrel sleeves, reentry springs, reentry spring guide rods, and coupling seats, each of which corresponds to a special mold.

Luo Qing gave an order, and a blacksmith poured molten steel into the diversion groove, and the molten steel began to flow into the mold along the diversion groove.

The first pistol, which was about to appear in the Ming Dynasty.
