Otaku Engineer in Great Tang Dynasty Chapter 1421: Vanadium steel sword, who will fight for the edge!

"Master, this thing is a battery? Would you like to try it with a light bulb?"

Workshop, in a laboratory.

Fu Bo heard that Li Zexuan said that the square thing in front of him was the first lead battery in the world, he was slightly surprised and couldn't help but say.

Li Zexuan nodded and said, "Of course I want to try! Fubo, I can't ask you to ask someone to bring a light bulb with less power and some wires!"

The lead-acid battery does not need to be charged when it is just finished, it can be used directly because it is full of chemical energy. The so-called charging is to use external electrical energy to regenerate the internal active material (lead sulfate) and store electrical energy. For chemical energy, the battery is not discharged at this time, and there is no active material (lead sulfate) in the electrolyte, so there is no need to charge!

"Okay! Master, wait a minute!"

Fubo smiled and left.

After a while, Fu Bo brought Song Xiaosi several light bulbs of different sizes and some copper wires. Li Zexuan removed the rubber on both ends of the wires, and one end of the two wires was connected to the positive electrode of the battery. On the pole, the other end was connected to the positive and negative screws at the end of the bulb, and the light suddenly turned on when the wire hit the tail end of the light!

"It's bright! It's really bright! It seems that the power supply capacity of this lead-acid battery should be more powerful than the voltaic battery you made earlier, because this kind of bulb voltaic battery can't light up at all!"

Fubo couldn't help exclaiming when he saw this.

In terms of electricity, he is also considered half-savvy. Although he is not as professional as Wang Ji, he understands the general meaning!

"Heh! Shanchang, your lead storage battery is really successful? Goodbye, it can light up such a big light bulb. What is the output voltage of this lead storage battery?"

Said Cao Cao Cao Cao arrived. After Wang Ji came out of the steelmaking plant, he planned to come and have a look. He didn't expect to see this scene as soon as he stepped into the laboratory. He couldn't help asking in surprise.

Compared to Fober, his questions are obviously more professional!

Li Zexuan smiled and replied: "In this lead-acid battery, the voltage of a battery pack is about two volts, and there are six battery packs connected in series. The voltage is about 12 volts, which is naturally higher than the voltage of a voltaic battery. Big! And the continuous discharge capacity of this lead-acid battery is much stronger than that of a voltaic battery. With this small light bulb, it can light up for twelve hours without a problem! And after the battery is used up, it can be charged. It can be used again after charging!"

"The voltage is 12 volts? Keep the light on for twelve hours? Can I charge after the battery runs out?"

Wang Ji was really shocked this time. He also used the voltaic battery made by Li Zexuan before. Each voltaic battery has only about one volt, not to mention that the power is not long lasting. If it is used to continuously send and receive telegrams, Basically, there will be no electricity in less than two hours!

Current batteries are far superior to voltaic batteries in terms of output voltage and ability to provide long-lasting power, and lead batteries can be recharged after they are exhausted, unlike voltaic batteries, which are Can only be thrown away!

These incomparable and incredible advantages make Wang Ji a little doubtful of life!

"Shanchang, can you tell Wang the principle of charging and discharging lead-acid batteries? This is the first time I heard that batteries can be recharged and recycled~!"

After a while, Wang Ji recovered from the shock, then looked at Li Zexuan expectantly and asked.

Although it’s getting late, Li Zexuan knows that if he doesn’t explain the principle of lead-acid battery charging and discharging to Wang Ji clearly today, according to the old guy’s temperament, he probably won’t be able to sleep tonight, in order to let the old man sleep. Feeling good, Li Zexuan took out a piece of blank rice paper, wrote the chemical equation on it with a pencil, and began to explain:

"Mr. Wang, the anode plate of this battery is made of lead dioxide, the cathode plate is made of lead, and the electrolyte is prepared dilute sulfuric acid. There is a separator in the electrolyte to separate the electrolyte between the two electrodes. Open to prevent short circuit of the electrodes. When discharging, the lead of the cathode plate interacts with the electrolyte to generate lead sulfate and water, which release electric energy; when charging, under the action of external electric energy, the lead sulfate reacts with the acid in the water to form fluffy Lead and sulfuric acid store electrical energy..."

It took nearly half an hour to explain the charging and discharging principle of the battery to Wang Ji. During the period, Wang Ji asked many technical questions, and Li Zexuan patiently answered them one by one. It's close to the sea time!

"Shanchang, this lead-acid battery is really amazing, especially now that the hydropower station and Yanhuang Academy in Lantian County are connected to electricity, the role of this battery is even more obvious! After the electricity is used up outside, you can Taking back the electricity generated by the hydropower station for charging, it was perfect! It was perfect! The old man really admired the mountain leader’s whimsical ideas!"

Wang Ji's eyes were getting brighter, and his gaze toward the lead battery became hotter and hotter. At this moment, he suddenly remembered that he had come here to look for Li Zexuan, but there was something serious, so he quickly said: "Oh! Shan Chang Vanadium steel has already been developed at the steelmaking plant. The old man has done experiments in private. This vanadium steel is indeed much harder than ordinary steel. Would you like to visit Shanchang?"

Li Zexuan looked at the pitch black sky outside and couldn't help but ask: "Bo Fu, what time is it now?"

After traveling for so long, Li Zexuan still has no accurate time and time judgment anytime and anywhere. He estimates that he will not be able to exercise this skill in his lifetime. He can only fully "control time" after the watch is invented later.

"Master, I should have just arrived at Haishi now!"

Fubo was silent for a moment and replied.

Hai hour, which is nine o'clock in the evening!

He actually worked in the workshop from one or two in the afternoon until nine in the evening, and didn't even eat dinner in the middle!

Not only did he not eat dinner, but neither did Fu Bo and Wang Ji!

"Don't watch! Don't watch! Watch again tomorrow! It's not early today, Mr. Wang, Fu Bo, this person is iron, rice is steel, everyone go back to eat and rest early! The body is our invention and creation The cost of new things!"

At this point in time, Wang Ji, a workaholic, even wanted to take him to "work" in a steel mill. Li Zexuan would not do that if he killed him. He still has a wife and children at home, oh, not yet Child, but it’s too late to go back and worry the daughter-in-law, right? Therefore, he waved his hand and said to Wang Ji and Fu Bo.

"Hehe! What the young master said is that the old man should take a step first! I am too old to hold it!"

Fubo said with a smile.

Wang Ji was unwilling, but seeing that Fu Bo had said the same, he didn't agree with him, so he had to clean up, and went out of the workshop with Li Zexuan and went to Yunshan!

He now lives in the teachers’ dormitory of the college, not Yunshan other college, because his title has not yet reached the professor level!

However, judging from Wang Ji's research enthusiasm in chemistry and the recent results, it is probably only a matter of time before he is rated as a professor in the academy!

"My husband, are you back? Haven't you eaten yet? I'll go and warm up the food for you!"

Back to the other yard, Han Yuxi heard the movement at the door and hurriedly greeted her from the house and said.

Apparently, she hasn't slept waiting for Li Zexuan to come back!

"Madam, why are you still up to sleep at this late? It's all because of your husband. I forgot the time when I was busy in the workshop, and I forgot to send someone to tell you!"

Li Zexuan said apologetically.

"Don't say that, my husband!"

Han Yuxi said hurriedly: "You are busy with major events in the workshop. Besides, when the child is not here, the concubine is not sleepy! Okay, let's not talk about it, the concubine went to the Xianggong hot~!"

Li Zexuan embraced Han Yuxi, kissed her forehead lightly, and said: "The lady is so considerate, and it is as good as giving her a few days to her husband~!"

Han Yuxi curiously asked: "What good thing?"

Li Zexuan smiled mysteriously and said: "It's a secret for now, but it must be a big surprise!"

.........................

The next day.

Li Zexuan went to the workshop again after having breakfast.

By the way, he has now sat in the position of Guohou. It is reasonable to not have to work so hard. Even if he eats, drinks and has fun every day, relying on the huge foundation he set before, he can guarantee a lifetime of worry-free food and clothing!

When I first crossed over, Li Zexuan thought this way. As long as I can be a master, I will eat and die forever, but sometimes, only when you really sit in that position will you understand you Responsibility!

Li Zexuan is now the head of Yanhuang Academy, the real master of tens of thousands of people in Lantian County, and the helm of the entire "Yanhuang Group". There are countless students behind him who are learning from him and making progress; there are countless The people are relying on him for food; there are countless craftsmen using his innovative technical tools to liberate productivity; and countless merchants are relying on him to get rich and realize their own value!

He can't stop!

He was a countryman who relied on engineering invention and creation, so he has the obligation to carry forward engineering in this era, and for him, creating some modern things in ancient times is also his pleasure. He thought, and is willing to make this Tang with him more advanced and stronger!

When I came to the steelmaking plant in the workshop, Wang Ji has already been waiting here. These two days are the weekends of the academy, so Lao Wang has no classes in the academy and can devote himself to "scientific research". went!

"Shanchang, look! This is vanadium steel! This is the vanadium steel made according to the three different vanadium-doped ratios provided by you!"

Wang Ji pointed to the steel piled on the ground and said to Li Zexuan.

"Well! First use these vanadium steels to make swords and armors, and then try the effects!"

Li Zexuan nodded and said.

The proportion of vanadium in vanadium steel is generally not high, about 0.025%-0.059%. The hardness of vanadium steel produced by different vanadium proportions is different. Which proportion is most suitable for swords? This kind of armor is most suitable for making armor, all of which need to be tested!

In addition, adding a certain proportion of vanadium to steel can create rebar for the skeleton of reinforced concrete building components!

Compared with ordinary steel, rebar has very good solidity and toughness. It is suitable for use as a steel frame in large engineering projects. It can significantly improve engineering strength and seismic resistance!

"Okay! Wait a minute for the mountain to grow!"

Wang Ji nodded in response.

There are all kinds of craftsmen in the workshop, and naturally there is no shortage of skilled blacksmiths. Wang Ji sends these vanadium steels to the blacksmith’s workshop and instructs the blacksmiths to use these three ratios of vanadium steel to build three sets of swords and armors. , The blacksmith's workshop suddenly began to get busy!

"Shanchang, do you say that this sword made of vanadium steel can really be sharp and cut like mud? There is also armor. The armor made of vanadium steel will definitely be better than mine. Should the armor used be strong?"

The temperature in the blacksmith's workshop was too high, and Wang Ji was too old, and he couldn't stand it. After he had asked the craftsman, he left the workshop, found Li Zexuan, and asked.

Li Zexuan smiled slightly and nodded: "Although I dare not say that cutting iron is like mud, if it is an ordinary iron sword, if it encounters a sword forged with vanadium steel, it will definitely suffer a lot of damage! As for the armor, this me I feel more confident. Under the same conditions, the superiority of vanadium steel armor is absolutely beyond doubt!"

Vanadium alloying can greatly increase the strength of carbon steel, especially under the process conditions of quenching and tempering, the performance improvement is more obvious. In a previous life, an accident prompted the application of vanadium in automotive steel. It is said that Henry Ford I was watching a racing game when a French car was crashed. When inspecting the car wreck, he found that a crankshaft made in Sweden was damaged much less than expected.

After testing, it was found that the steel contained vanadium. So Ford used vanadium alloyed steel to make key parts of Ford cars to better resist road vibration and fatigue. He once said a famous saying: "If there is no vanadium, there will be no cars."

Because a very small amount of vanadium can make steel obtain excellent performance, people had a vivid evaluation of the role of vanadium in steel at that time-vanadium is a vitamin in steel.

It can be seen that the use of vanadium steel to make armor is not to say that it is absolutely invulnerable, but it can definitely resist most cold weapons!

"It's amazing. Who would have thought that just adding a little vanadium to steel~IndoMTL.com~ can improve the performance of steel so greatly, it's incredible!"

Wang Ji muttered to himself.

"Hehe! Wait, Mr. Wang, I'll go draw a drawing, I plan to make something new!"

Li Zexuan knew that building sword armor could not be done in a short while, at least it would take a long time, so he said to Wang Ji.

Wang Ji's eyes lit up when he heard the words, "Oh? Shan Chang has a good idea again? I don't know what new things are going to be built this time?"

"Hehe! You will know Mr. Wang in a moment! After the sword armor is built here, remember to let someone come and notify me!"

Li Zexuan didn't say clearly, he smiled for the teacher.

When Wang Ji saw this, it was not easy to ask, he could only answer.

Li Zexuan returned to his office in the workshop and started drawing drawings. Song Xiaosi brought him food at noon. He finished eating three by one, and then continued to draw drawings. A thick pile of drawings has been piled up on the entire desk, which shows that what he is going to build this time is not simple!

"Mountain long, the sword and armor are ready! Take a look!"

At around Shenshi, Wang Ji brought two studio servants and three pairs of swords and armors to Li Zexuan's office and said excitedly.

"Oh~? How effective is it? Has Mr. Wang ever tried it?"

Li Zexuan put down the pen, stood up, and asked with a smile.

"I tried it! I tried it! This sword is really as the mountain leader said, ordinary iron swords can be easily cut by it! It is too sharp! As for this armor, bows and arrows cannot be shot, it is simply The strong can't be strong anymore!"

Wang Ji said ecstatically.
