Heavenly Dao Formula

Outside the east gate of Jinxia City, next to Yantian.

　　 A huge brick stove suddenly appeared on the beach.

It is about 9 feet high, with an inner diameter of more than 15 feet, and the outer ring is made of bricks for three full layers. The cracks in each layer are filled with fine sand to prevent heat leakage and strengthen the furnace wall. Pressure capacity.

　　 By the side of the stove, the soldiers were adding raw materials back and forth, and it was Mo Yun, the head of the Bureau of Mechanical Engineering, who commanded them.

　　 "Attention, the order of the iron ingots must be correct, and remember to read the markings on the raw materials!"

　　 "One bar is up, two bars are down, and the iron ingots are mutually staggered, leaving a gap!"

　　 "If you find a problem, don't make it hard, you must report it to me, understand?"

　　 "Yes, my lord!"

　　 "This is the new test product you are talking about?" As the familiar voice sounded, Ning Wanjun shook off his guard and walked quickly to Xia Fan's side. "Did you hear the incredible whispers again?"

　　 "I have seen your Highness!" When the busy crowd saw the princess appearing, they all bowed their heads.

　　 "You continue to work on your own work, don't make trouble for me!" The princess waved her hand.

　　 "Hey!"

Xia Fan sighed helplessly. Ever since she pointed out that Luo Qing was the listener, she now regarded herself as a member of the listener, even though he had never heard any whispers, but when the other party met He always asked if he had lost his mind in a thoughtful way, which made him dumbfounded.

　　 "It is indeed a new experimental project, but it has nothing to do with whispers." Xia Fan curled his lips, "Speaking of which, why don't you ask Miss Luo if she is still rational?"

　　 "People are more serious than you at first glance, do you have to ask?" Ning Wanjun said without thinking, "I never worry that she will have any problems."

　　 "Thank you for your trust." Luo on the side nodded gently.

　　 Okay, I'm getting together again. Xia Fan rolled his eyes silently, "In fact, I only started this project. The real preparation and implementation was Miss Mo Yun."

　　 "Oh? Tell me what?"

　　 "This has to start with Miss Luo's ability..."

Xia Fan’s thoughts on the day were not just in his mind, but he ran into trouble when he tried to work out a production flow chart at night-he did not know the level of smelting technology in this era, and he did not have any special skills. Knowing the modern steelmaking process is just like the theory belongs to the theory, but it has become a difficult thing to transfer to practical operation.

　　 So he approached Mo Yun with the idea of ​​trying.

　　 And the latter actually has a lot of accumulation in this area.

After all, the Ministry of Industry manages the entire production and construction of Qiguo, and naturally also includes iron and forged steel. For one of the directors of the Machinery Engineering Bureau, even if he has not personally operated it, the technology and craftsmanship in this area will never be unfamiliar. .

　　 After one night of intense exchanges between him and the other party, an experimental plan that meets the level of the times and surpasses the times was born.

　　 From Mo Yun’s oral account, Xia Fan learned that Qiguo’s smelting technology is not backward, or in the Yongguo period, some people have realized that steel is between pig iron and wrought iron and is an excellent sword-making material. It's just that iron is more difficult to melt than copper, and bronze is still the mainstay of large metalware.

　　After a hundred years of research, the popularization of tower kilns and manpower blowers has made the output of iron steadily increased. The Ministry of Industry naturally shifted its attention to steel with higher strength. The method they advocate now is to burn pig iron into molten iron and pour it on wrought iron sheets, and the two are mixed to form steel. In popular terms, it is to fuse iron with high carbon content and iron with low carbon content to obtain iron with moderate carbon content, which is the so-called steel.

　　 Although the Ministry of Industry does not know that the element that determines the performance of steel is carbon, it still produces qualified smelted products based on experience, which is quite amazing. However, this method is limited by the temperature of the molten iron. There are only a few steel ingots in each batch, which are generally used by the Ministry of Industry to build the most sophisticated weapons or the core components of machinery and equipment. Even if the use is saved, steel is still in short supply.

　　 It can be said that as long as the furnace temperature cannot be raised, the scene of large-scale smelting will be difficult to achieve after all.

　　 And Xia Fan's plan is to directly enclose a furnace, layer the pig iron and wrought iron, and melt from the upper layer. The molten iron will increase the chance of contact with air during the downward flow process, and further reduce the carbon content-this is also considering that the wrought iron smelting process at this time is mainly stirring, and the carbon content may be higher overall, so Just make this arrangement.

　　Once the restriction of the heat source is freed, the entire process flow becomes simple and easy to implement.

After hearing that Ning Wanjun’s eyes had lost focus, she was obviously confused by a lot of nouns, "Uh...I roughly understand the principle. According to you, if this method is successful, my soldiers will not Lack of steel knives and hard armor?"

　　 "You can think so," Xia Fan smiled, "But its ultimate goal is to make soldiers no longer need steel knives and hard armor."

　　Improving weapon performance is only an incidental use of material technology after a breakthrough. Its greatest significance is to go back and improve the quality of the original device, thereby further expanding production capacity.

　　 Luo has only one lightly. It is difficult for a strong man to rely on her ability to reach the position in one step, but the method of heating is not limited to dragon scales. With a high-quality steel furnace, the arc produced by the seismograph streamer can also have the same effect. Compared with the indescribable Listener spells, the magical implements engraved with the amplifying circuit talisman are at least hopefully copied in batches.

　　The key lies in where this initial melting pot came from.

　　 The answer is right now.

　　 "My lord, all the ingredients are in place," the soldier reported.

　　 Mo Yun solemnly ordered, "Check the ignition mechanism."

　　 "Report-the ignition mechanism is normal!"

　　"Close the bottom furnace door~www.ltnovel.com~Report-the furnace door is closed!"

　　 "Everyone evacuated."

　　 "Yes, all staff withdraw from the furnace area!"

　　 When everything was ready, she walked up to the three of them, and Chao Luo nodded gently, "It's up to you next."

　　 Luo gently stretched out one palm and pointed it at the brick stove, "I will do my best."

　　 Under the gaze of everyone, a sword blade with a faint golden light appeared quietly above the furnace top.

　　 Then, it slowly descended, from the hole at the top into the furnace.

　　 is blocked by the wall, the vision is invalidated here, Luo Qing can only rely on the experience and feeling accumulated in the previous simulation exercises-after she leveled the blade, she tried to close it in the direction where she was.

　　 At this moment, the "ignition device" was triggered.

　　 It is essentially a falling platform, and the iron ingot on it is pulled by a rope. When the dragon scales thin as a cicada wing cut the rope, the iron ingot slams on the blade.

　　 Luo lightly felt this change.

　　 The outer layer of the dragon scale temporarily disappeared, and the power flowing in the blade suddenly poured into the iron ingot. This heat quickly spread, and quickly ignited the entire upper layer of the furnace.

　　 "Boom——"

　　 Everyone saw that the top of the brick furnace spewed out a flame of several meters high!
