The Rise of Ming Dynasty 1646

Chapter 39 Ganzhou Trip

After a few days, the hot air chamber began to be put into operation.

Usually two of the three hot air chambers are heated, and one completes the fire extinguishing of the heating, and is connected with a blower to send hot air to the ironmaking furnace and steelmaking furnace.

After the temperature of the hot air chamber is lowered, the next hot air chamber is enabled to send hot air, and the cooled hot air chamber is ignited to heat up.

Three hot air chambers circulate heat to keep hot air constantly.

The temperature of the crucible steelmaking furnace immediately rose, and now even low-carbon steel can be melted to a liquid state.

The furnace temperature on the side of the ironmaking blast furnace has also risen a lot.

Zhu Linmi asked someone to make a long and narrow groove, and the molten iron from the blast furnace flowed through the groove first, and the craftsmen continuously sprinkled limestone, lime, rust, iron ore powder, etc. into the groove.

Due to the high temperature of the molten iron, the molten iron is not easy to thicken. When flowing through these desulfurization and dephosphorization agents, most of the sulfur and phosphorus impurities are precipitated through chemical reactions.

Hot metal pretreatment desulfurization and dephosphorization has many advantages.For example sulfur will be partially dissolved in molten metal in the presence of slag.In addition, molten iron contains a large amount of reducing elements such as silicon and manganese, which can greatly increase the activity coefficient of sulfur and phosphorus, so that these impurities can more fully react with desulfurization and dephosphorization agents.This is also the reason why pretreatment desulfurization and dephosphorization are generally carried out in the modern steelmaking industry.

After such treatment, sulfur and phosphorus, the most harmful impurities in molten iron, have been greatly reduced. As raw materials, the quality of refined steel is also better.

Especially when the molten iron is still in a liquid or pasty state, it is also possible to carry out the process of stirring and decarburizing. Although it cannot reach the level of directly producing wrought iron, the carbon content has been greatly reduced.

Even the steel produced by local methods in many places nowadays is not as good as the iron produced in the blast furnace of Suji Iron Works.

One of the most important purposes of Zhu Linmi's time-consuming effort is to preheat the iron-steel integrated production model in advance.

When you want to use the open hearth furnace to make steel in the future, you only need to upgrade the steelmaking furnace.

Before leaving the iron yard, Zhu Linmei gave Lu Ning the blueprint of a pair of short swords, and ordered him to cast a small protrusion on the front end of all the flintlock barrels.

The dagger shown in the blueprint is one and a half feet long, with a narrow blade, and the position of the hilt is replaced by a circular sleeve with a hollow groove in the shape of a "B".

Lu Ning picked up a barrel, and then picked up a small piece of scrap iron and tried to roll it on the barrel. After a long time, he finally understood what Zhu Linmin meant by sticking the dagger on the barrel.

It turns out that the protrusion on the gun barrel is a tenon. After putting on the sleeve and turning it back and forth, the tenon can be inserted into the hollow groove.

This is exactly a bayonet bayonet that was commonly equipped in various countries in the eighteenth century.But it is an unprecedented invention nowadays.

After Zhu Linmei had arranged the iron yard, she rushed to the Ganzhou Military Weapons Bureau without stopping.

Even with a hydraulic forging machine and a pedal boring machine, if you want to manufacture [-] sets of bust armor and [-] flintlock guns within two months, it is definitely not the same as the less than [-] blacksmiths in Suji Iron Works and Lu Lu. Ning and more than a dozen firearms craftsmen can do it.

What's more, these people have to make new forging machines and boring machines. In addition, although the eight hundred cavalry swords are not complicated in craftsmanship, they still require a lot of manpower.

He estimated that at least one hundred fifty or sixty skilled craftsmen were needed to ensure that the weapons and equipment of the Dragon Guards could be in place in time.

It is almost impossible to recruit so many skilled workers in Longnan or even Ganzhou in a short period of time.

So he thought of the Ganzhou Arms Bureau.

It's not that the Military Weapons Bureau made weapons and equipment for him. New things such as flintlocks and plate armor are relatively complicated in craftsmanship and require equipment. It is unlikely that the Military Weapons Bureau can make them within two months.

The second is that the quality of the products produced by the Ministry of Industry of the Ming Dynasty is famous all over the world, and the Military Weapons Bureau under the Ministry of Industry is the hardest hit area.The wages of craftsmen are low and they have no enthusiasm for labor.Officials at all levels of the Ministry of Industry are corrupt, and the materials they purchase are of inferior quality.In this way, how can the things made not rot.

Zhu Linmi's trip was to borrow some people from the Ganzhou Military Weapons Bureau.

Most of the craftsmen in the Ministry of Industry are experienced hands. As long as they are given generous treatment and strict quality control, they can produce high-quality products.

After borrowing these craftsmen, coupled with the advanced equipment of Suji Iron Works, it is possible to meet Zhu Linmi's requirements for efficiency.

The Ganzhou Arms Bureau was a weaponry manufacturing department attached to the former Ganzhou Guards. After the Qing army attacked the front line of the Yangtze River, it expanded several times and was responsible for the supply of weapons to the entire Jiangxi Ming army.

Zhu Linmi's car stopped at the outskirts of the southwest of Ganzhou Mansion, where the Weapons Bureau was located.

Due to the continuous temporary expansion, the Ganzhou Armament Bureau covers a very large area, but various workshops are scattered all over the place in a disorderly manner.At a glance, there are fifty or sixty work sheds of various sizes.

There are many craftsmen, vehicles, etc. shuttle back and forth between the buildings.Almost all the work sheds were filled with black smoke billowing, and the sound of clanging could be heard endlessly.

It took Qiao Qian a long time to catch a person in charge and ask him to find the ambassador of the Military Weapons Bureau.The man searched for a while in the Armament Bureau, and finally came out with a thin man who was nearly thirty years old.

When the thin man learned that the plainly dressed young man in front of him was actually a county king, he hurriedly knelt down to worship, "I didn't know His Highness was coming, but I never greeted him from afar. Xu Erlu, the secretary of the Ministry of Industry and Commerce, is currently serving as the deputy of the Ganzhou Military Weapons Bureau." make."

Zhu Linmei lifted him up and saw that his face was covered with black ash, and the words "Chuan" were washed out by the sweat from his forehead. He was obviously a hard-working official.

He followed Xu Er Road into a dilapidated house made of random planks, with various blueprints and official letters on the table, which seemed to be the office of Siwu Xu.

It took a long time until a little official covered in ashes brought tea.

"I'm training in Longnan," Zhu Linmi picked up the teacup and glanced at it, then immediately put it down, "But the new army is training for the first time, and the equipment is lacking..."

Xu Erlu immediately bowed and said, "Your Highness, the lower officials are only in charge of the production of utensils, and the military equipment in the warehouse must be ordered by Yang Butang."

Zhu Linmei smiled and shook her head, "I'm not here to ask for weapons. I want to borrow some people."

"People? Who is Your Highness borrowing from?"

"I need 160 military craftsmen. I have my own place for forging military weapons in Longnan." Knowing that there is no convenience for free, Zhu Linmi added, "The silver for these military craftsmen will naturally come from me. The other As for the craftsman, I will give another five taels of silver to the Armament Bureau to make up for the recruitment."

The craftsmen of the Military Weapons Bureau are usually both craftsmen and military, so they are called military craftsmen.

Xu Er looked embarrassed on the road, "If your highness had come a few months earlier, it would be no problem for the six hundred craftsmen of the Military Weapons Bureau to lend you some." He sighed and continued, "But the recent war in central Jiangxi has been tense. Liu Yipeng's troops have captured Yuanzhou Mansion, and only Wan'an County is still struggling in Ji'an Mansion. Yang Butang is recruiting a large number of soldiers, and it is very difficult for the Military Weapons Bureau to find more manpower now."
