Ganzhou Tieye, Su You and Shi Yong are inspecting the blast furnace.

In the Song Dynasty, open-hearth furnaces were more popular because they could smelt recycled iron materials and were more useful than blast furnaces, which had high output but could only be used for ore refining.

However, because Zhang Tianshi discovered two more metals here, Su You had to come.

Nickel, chromium.

These two metals did not appear in Su You's original periodic table. This was completely discovered by Zhang Tianshi.

But Zhang Tianshi didn't know the functions of these two metals, but Su You did.

The simplest one is metal plating, and the more advanced one is stainless steel.

The Song Dynasty has also been studying metallography for thirty years now. Now every discovery of a new metal will lead to a large wave of alloy experiments by the Ordnance Supervision and the Chemistry Branch of the Institute of Technology.

After more than 300 tests, Shi Yong obtained an extremely corrosion-resistant steel at Ganzhou Iron and Steel Co., Ltd., containing 18% chromium and 8% nickel, and added a small amount of sulfur and phosphorus to improve its processing performance.

.

Although it is corrosion-resistant and not easy to rust, it also has the disadvantage that its hardness is not high enough and its metallographic structure cannot be changed through heat treatment.

It can only be used as containers, tableware, medical equipment, and indoor high-end decorative faucet fittings. Shi Yong called it 304 stainless steel to commemorate the number of tests.

Within the Polytechnic Institute, it is called Ya88 stainless steel to indicate its composition ratio.

This is undoubtedly a huge metallurgical achievement. In addition to stainless steel, chromium anhydride can be produced by heating chromium ore and soda ash limestone, and then treated with sulfuric acid to obtain an electroplating solution.

Today's R&D personnel in large industrial and mining industrial bases such as polytechnics, iron smelting plants, and chemical plants are the happiest group of people.

Ever since Su You started the interest group thing, science and engineering talents from all over the country who like to do research often find partners who like the same project, and spontaneously set up research and development groups like mushrooms after rain.

The topics of many research and development groups often seem very nonsensical, such as water-splitting engines, element converters, perpetual motion machines, aircraft, refrigerators, gasoline-powered equipment... But Su You very much encourages such behavior.

There have been many achievements, such as the vacuum mirror-coated glass thermos flask liner.

However, this thing is not cheap. It is still something that rich people can afford, and because it is too easy to break, the internal officials are very resistant to it.

It is human nature to rather boil water for nobles than to be punished for breaking valuables.

After getting the vacuum insulated cup made of stainless steel by Shi Yong, Su You tossed it in his hand happily: "This thing, plus wolfberry ginseng slices and tea leaves, is the standard for middle-aged successful men..."

After saying that, he frowned again: "Since we have such good things? Then we need to improve the processing of the shell? At least we have to compare it with the sword processing technology of high-quality swords."

"Such a thing? How can I take it to Your Majesty to ask for credit for you?"

Shi Yong smiled and said: "Isn't this a test product? Soon, the finished product will be produced soon..."

Su You then expressed his satisfaction: "Then this experimental product belongs to me. Where is the Heavenly Master? This stainless steel is indispensable for his contribution."

Shi Yong said: "Tianshi is obsessed with Taiyi Avenue. It is a piece of cake for him to discover two metals? He is now studying electricity."

"Oh." Su You said happily: "I can definitely help with this..."

Is there anything wrong with that? Winding motors and repairing loudspeakers were serious part-time jobs for a young township cadre with an early science and engineering background.

Later, it was upgraded to repairing computers in the entire township? Installing system software? Various office software? Dealing with minor problems with printers and fax machines? Teaching operating skills...

There are even some powerful township cadres who can even handle small hydropower, small farm machinery, small hardware equipment, tractors, and even simple car troubleshooting in the township.

Of course, with the development of society? When there are professionals in these fields even at the village level, there will be no need for township cadres to act as panacea.

The township Su You was once in charge of was too remote and had a large reserve of intangible cultural heritage talents, but there was only one electrician.

Because he graduated from a polytechnic, in the impression of the fellow village head, you should be able to do all the things we don’t understand, and he was often asked to help the electricians.

Old electricians are also old-school people. Those who can repair by themselves will never let the organization spend money. Those who can process parts by themselves will never go out of the village to buy them. The older generation will "three good years, three bad years, repair and repair again".

The hard and simple style of "Three Years" has been brought to its extreme.

It is not difficult to wind the coil, and it is not difficult to install the coil. What is difficult is the wiring.

But for Su You, who has a foundation in science and engineering, the motto is easy to master.

However, he can't make a permanent magnet now. This thing can only be tested by Tianshi Mansion with its strong economic strength. All he knows is one term, which is the barium ferrite sintering process and then magnetization. He doesn't know anything else.

.

Barium salt has been widely used in the Song Dynasty. It is one of the earliest elements established by Zhang Tianshi. It is widely used in porcelain whitening and glassware manufacturing.

Today, I was favored by Master Tian. It seems that the permanent magnet material sintering process has matured.

After running to Tianshi's laboratory, Zhang Xiangzhong saw Su You: "Brother Xian, after discussing your design, we think it is feasible, but the actual operation is a bit complicated, so you have to come."

Su You said happily: "Brother, have you developed permanent magnets?"

Tianshi pushed two black cylinders half a circle: "No, but if you can wind up the motor today, our Tianshi Mansion will agree to this project."

Su You was dumbfounded: "It's not done yet? Then what is this?"

The Heavenly Master said: "This is hand-polished with natural magnets. It takes a lot of effort to find pure magnets and polish them into such a shape."

Su You looked at the two fist-sized rotors on the table: "Then what's the point..."

The Heavenly Master has long been accustomed to countless failures during the long-term experiment, and his self-cultivation and tolerance are not generally good: "Try it first and see if it is as miraculous as the wise brother said."

Su You couldn't help but feel a little embarrassed: "In the end, it's senior brother who is better behaved, I just lost my temper."

After saying that, he rolled up his sleeves and said, "Let's try it!"

Strictly speaking, this also requires calculating the magnetic flux, and then determining the number of coil turns based on the diameter and resistance of the enameled wire. However, it is just a principle test now, and there is no need to be so precise.

Soon Su You wrapped the twelve coils, wrapped them in wax paper and stuck them in the stator slots. Then he started to connect the coils' connectors to make the stator of the three-phase motor.

After that, the paint is dipped and baked to harden the enameled wire, and then the magnet rotor is put in.

Using the same principle, Zhang Tianshi led his scientific research team to imitate Su You's method and create another one.

Add the shell, place the two motors at both ends of the experimental table, and connect the electrodes.

Install a pulley on one motor shaft and a fan blade on the other motor shaft.

Let a little Taoist shake the big wheel, and the big wheel drives the motor shaft to fly through the belt.

While the motor here is spinning, the blades of the motor on the other side are also spinning.

"Hahahaha!" Zhang Tianshi laughed while stroking the table: "My brother is truly a heavenly man! He has truly become one."

Su You was very satisfied with his craftsmanship and pointed to the motor that the little Taoist priest was shaking: "This is a machine that relies on mechanical power to drive a coil to cut magnetic lines of force and generate electrical energy. It is called a generator."

After speaking, he pointed to another one: "That one is a device that uses electrical energy to drive the rotor to rotate and restore the electrical energy to mechanical energy. It is called an electric motor."

"With this set of equipment, we can use mechanical energy to generate electrical energy. Then transmit the electrical energy to other places as an input source of mechanical power."

Zhang Tianshi nodded: "Wonderful, now the Tianshi Mansion prepares a huge amount of tablets of medicine. The medicine shop is set up next to the waterwheel house. The medicine is easily affected by moisture. It is set next to the boiler, but the smoke and fire affect the properties of the medicine."

"Wind-powered workshops are useful, but they are affected by the weather. It is even more troublesome to use animal power while raising livestock."

"With Xiandi's equipment, we can make medicine far away from the river water boiler. Not bad! Xiandi is really thoughtful!"
