Time flies so fast, before Han Wang finished class at noon, Lao Qian ran over panting like a cow, and as soon as he entered the courtyard, he called out repeatedly, "Mr. Han, Mr. Han, the equipment for steelmaking is ready, and the things you want have been brought, how about going to take a look now?" ”

Han Wang replied at the window, "After lunch, take the children with you, by the way, if you have something to discuss with Gong Qian, go to my house to talk." ”

Lao Qian was anxious in his heart, whether this steel could be made or not was related to his net worth and life, Han Wang, a slow man, really made himself angry.

Thinking that there were still people to ask for, I had to follow Han Wang obediently, the weather began to heat up, and the sweaty old money really had the momentum to start a business.

Han Wang told Lao Qian about the children's practice in the steel plant, and the old money is absolutely thorough, and these children have been practicing in the steel plant for a few years under the leadership of Han Wang, and they are steadily proficient talents in the industry.

As a real business leader, he deeply knows that the most lacking thing in this era is talent, otherwise how could Lao Qian give a thousand yuan as soon as he saw Han Wang.

You see, once this new steelmaking method is successful, it will not be a problem to earn tens of thousands of yuan a year by virtue of its own 30% shares. Thinking of tens of thousands of yuan, Lao Qian felt that Han Wang's meal at this time was too luxurious. He couldn't wait to shout, as long as you go and refine the steel first, you can choose the delicacies of the mountains and seas, dragon liver and phoenix gall.

You should learn from my old money to see if these eyes are the same as pandas, and why? I didn't sleep at all this night, but prepared utensils and labor overnight, and loaded them in batches and cars, and waited at the city gate before dawn, and when the city gate opened, I was the first to jump out of the city.

In the end, Lao Qian couldn't bear to protest, "Time is copper money, wasting time is to make money and kill people, you just take a knife and stab me twice!" ”

Han Wang suddenly saluted, and pulled it to the height of Everest, "Old man Qian, you know Old Man Lu!" Disrespectful, disrespectful! Forget it, your nurse's cooking skills are really not as good as Hua Niang, and then listen to your urging, I don't feel in the mood at all, just don't eat! ”

Hua Niang was caught in Erlong Mountain, and the old Qian family took care of Qian Keqian's loving nurse and served as a cook.

Han Wang put the food box in a large bamboo basket dedicated to collecting tableware, and Lu Chou Lu Hai would take care of the cleaning and maintenance work in exchange for a small red flower.

Han Wang asked Feng Ju to wait for the students to finish eating, Lu Chou and Lu Hai cleaned up, and then went to the Fengzhuang Iron and Steel Plant by the Muddy River together.

Lao Qian pulled up Han Wangfei, who had finished his homework, and jumped into the carriage as if he was in the carriage, and flew away with a smoke, at least Han Wang could feel the smell of drag racing.

A large melting pot with a height of nearly two meters was erected in the open space by the river, several masters were already making various preparations, and a large bellows was pushed and pulled by two people at the same time, and the fire was already burning, just waiting for Han Wang to use the means of turning stones into gold.

Since the Tang and Song dynasties, steelmaking has mostly been made by frying steel, that is, raw wrought iron is fried together, and then forged into 100 steels.

Han Wang has studied the standard saber for special forces made of special steel, in which carbon content and corrosion-resistant components are key, but at present, those components that can resist corrosion (i.e., stainless steel) cannot be found at all.

Therefore, the focus is to reasonably control the carbon content, too high toughness becomes worse, too low hardness is not enough, the best proportion is to control the carbon content at 1 to 1.2 percent.

Due to the lack of experience of ordinary blacksmiths in the method of frying steel and forging, each batch of 100 steels produced is unstable, and only master blacksmiths with decades of experience can master the skills, so it is not surprising that peerless magic soldiers are rare.

Now Han Wang is going to demonstrate this secret recipe in public, and it is a weapon comparable to that created by a master, which is simply against the sky.

In the era of cold weapons, if an army is equipped with such anti-heaven weapons and armor, the attack power and protection power are undoubtedly huge, and more importantly, the psychological advantage of one's own soldiers will be increased, and the technical and tactical level will be better played, and the deterrent effect on the enemy is naturally self-evident.

If Han Wang's experiment is successful, it means that this advantage will be realized.

Han Wang stepped forward and saw that Ou Fei had skillfully arranged all kinds of equipment, and the workers were starting the normal steelmaking operation. Although Han Wang had done research on modern steel, he really lacked knowledge of ancient steel refining, so he asked Ou Fei to refine a pot of steel in his own way in advance to make a steel knife.

Then he used the methods of later generations to make steel knives, and compared them with each other to see how effective the new steel was.

Soon, the molten pig iron and wrought iron under the guidance of Ou Fei have begun to be smelted and are about to be baked.

Suddenly, Ou Fei loosened the outlet of the molten iron, and the two strands of molten iron converged into a pot, and after a short time, he got an extremely brilliant piece of steel.

After that, it is mainly folded and forged by hand, a total of 36 times, to become a hundred steel, and then by Ou Fei, a master who is good at making knives, and finally through ice water quenching, a swarthy hundred steel knife is presented in front of everyone.

Of course, this is the body of the steel knife, and then it will be handed over to the master who finely sharpens the edge decoration to perform the handicraft, which is not the concern of Oufei.

Han Wang also took advantage of this time to start his own steelmaking operation in front of the furnace, at this time, the disciples of the school also came to the steel plant to carry out practical activities, knowing that this test was very important, they didn't dare to speak loudly, just looked at the steelmaking process, characteristics, and the principle that Han Wang introduced to everyone.

Han Wang asked the master to smelt ordinary iron ore, and in the process also used the steel frying method, but it added quicklime to the molten iron, and after continuous frying and stirring, a piece of wrought iron with high purity was obtained, and the residue was removed and returned to the furnace.

Then he took out a package of graphite powder and added it to it, so that a total of three pots of graphite powder were refined, and the graphite powder in each pot gradually increased to obtain three pieces of high-carbon steel, which were directly made into knives and then quenched with ice water.

Oufei and Han Wang are all taken a quenching, although repeated quenching can enhance the hardness, but a quenching can best reflect the quality of steel, so that under the witness of everyone, the Great Song Dynasty waist knife, Ou Fei's knife and Han Wang's three knives are all on the table.

Ou Fei stepped forward to carefully observe the quality of Han Wang's three knives, although Ou Fei followed up the whole process of refining, but what Han Wang added must have his reason, I don't know what the result of these three knives will be compared to his own? Thinking of this, pick up each knife one by one and feel its texture.

Ou Fei first picked up the waist knife and the knife he had just made, and slashed at each other, and the waist knife was nearly a centimeter or so by Ou Fei's knife, which is worthy of being a good knife for sharpening iron like clay. Everyone applauded Master Ou!

Then Ou Fei picked up his knife, handed Han Wang's knife to the master to fix it with pliers, and then slashed it hard, and heard a "ding" sound, Ou Fei's knife was actually knocked into a gap, but Han Wang's knife did not roll the blade, only left a white mark on the edge of the blade.

Everyone exclaimed, this Oufei's knife can be regarded as sharpening iron like clay, but it was collapsed by Han Wang's knife, so how hard should Han Wang's knife be, and how sharp should it be?

Ou Fei's face did not change color, and then fixed his knife, and used Han Wang's second knife to slash the experiment, and sure enough, the second knife actually cut into Ou Fei's blade.

The third knife Ou Fei used the standard waist knife to test, and it was really as Han Wang said, and the blade of the half-cut waist knife flew into the air, and it was actually cut in two, this is an absolute divine weapon!

Ou Fei watched the blade fall down, and laughed, "Mr. Han, your new steelmaking method can really be described as 'steel in steel', and it will definitely be heard all over the world in the future, and it will be famous in history!" ”

Han Wang breathed a sigh of relief, it seems that this method of removing impurities and increasing carbon has worked, and the high-carbon steel practiced is more powerful than the craftsmanship of masters like Ou Fei, and the method is very simple, anyone except a fool can learn it, and it must be very fast to promote.

I had to build my weapons, armor, and equipment, all of which had to be of the best steel, and it was the wisest decision to save myself on the battlefield.

Then the new steel will trigger a rush to buy, and a fortune is in sight!

'Beautiful, beautiful, drunk, drunk, drunk......'
