Chapter 1416 Motors

Ganzhou Iron Metallurgy, Su You and Shi Yong are inspecting the blast furnace together.

The open-hearth furnace is more popular in the Great Song Dynasty now, because the open-hearth furnace can smelt the recovered iron, and the use is stronger than the blast furnace that can only refine ore although the output is higher.

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

Nickel, chromium.

Su You's original periodic table did not have these two metals on it, and this was entirely a discovery by Zhang Tianshi.

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

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

For the study of metallographies, the Great Song Dynasty has now gone for 30 years, and now every new metal discovery will lead to a large wave of alloy tests in the Ordnance Supervision and the Chemical Branch of the Institute of Science and Technology.

After more than 300 tests, Shi Yong obtained an extremely corrosion-resistant steel in Ganzhou Iron Metallurgy, containing 18 percent chromium and 8 percent nickel, and added small amounts of sulfur and phosphorus to improve its processability.

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

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

Inside the Polytechnic Institute, it is called Unitary Stainless Steel, indicating its composition ratio.

This is undoubtedly a great metallurgical achievement, in addition to stainless steel, chromium ore and soda ash limestone are used to coheat chromium anhydride, which can then be treated with sulfuric acid to obtain electroplating solution.

At present, the R&D personnel of the large industrial and mining industrial bases such as polytechnics, iron metallurgy, and chemical factories are the happiest group of people.

Since Su You started the interest group, science and engineering talents who like to study in various places often find partners who like the same project, and spontaneously set up research and development groups like mushrooms after a rain.

Many R&D team topics often seem very nonsensical, such as water splitting engines, such as elemental converters, perpetual motion machines, aircraft, refrigerators, gasoline-powered equipment...... But Su You strongly encourages such behavior.

There have also been a lot of achievements, such as the vacuum mirror-plated glass thermos liner.

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

It is normal for people to rather boil water for the nobles than to be punished for breaking valuables.

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

After speaking, he frowned: "Since there are such good things, then we have to do a little better in the processing of the shell, at least we have to compare the sword processing technology of the high-quality sword." ”

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

Shi Yongyun smiled: "Isn't this an experiment?" Soon, soon the finished product will be ......"

Only then did Su You express his satisfaction: "Then this test product will belong to me." What about the Celestial Master? This stainless steel is indispensable to him. ”

Shi Yong said: "The Celestial Master is obsessed with Taiyi Dao, and the discovery of two metals is a matter of great deal for him, and he is now studying electricity. ”

"Oh." Su Youle said: "I can completely help with this......"

There is nothing wrong with this, winding the motor and repairing the loudspeaker, it is a young township cadre with an early science and engineering background, and he is working part-time.

Later, he upgraded to repair the township's computers, installed system software, various office software, dealt with printers and fax machine glitches, and taught operation skills......

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

Of course, with the development of society, even at the village level, there are professionals in these fields, and there is no need for township cadres to be a panacea.

The township that Su You was once responsible for was too closed, and the reserve of intangible cultural heritage talents was a big one, but there was only one electrician.

Because he graduated from a polytechnic college, in the impression of the old chief, you should know everything we don't understand, and often ask him to give an electric hand.

The old electrician is also an old-fashioned person, who can repair it by himself, never let the organization spend money, can process parts by himself, and never go out of the village to purchase, and the hard and simple style of the older generation of "three years of good, three years of bad, and another three years of sewing and repairing" has been brought into full play.

It's not difficult to wind the coil, it's not difficult to install the coil, it's the wiring that is difficult.

However, for Su You, who has a foundation in science and engineering, that song recipe is easy to master.

However, he can't come up with a permanent magnet now, this thing can only be tested by the Heavenly Master Mansion with strong economic strength, all he knows is a term, that is, barium ferrite sintering process, and then magnetization, and nothing else is known.

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

Today, I am favored by the Heavenly Master, and it seems that the sintering process of permanent magnet materials has matured.

Running to the Heavenly Master's laboratory, Zhang Xiangzhong saw Su You: "Brother Xian, after we discussed your design drawings, we think it is feasible, but the actual operation is a bit complicated, and you have to come." ”

Su You said happily: "Brother has researched the permanent magnet?" ”

The Heavenly Master pushed through the two black cylinders and half a circle: "No, but if you can wind the motor out today, my Heavenly Master's Mansion will agree to this project." ”

Su You was stupid: "It's not done yet?" So what is it? ”

The Heavenly Master said: "This is hand-polished with a natural magnet, and it takes a lot of effort to find a pure magnet and polish it into such a shape. ”

Su You looked at the fist-sized two rotors on the table: "Then what does this mean......

The Heavenly Master has long been accustomed to countless failures in the process of long-term experiments, and his cultivation temperament is not ordinarily good: "Let's try it first, and see if it is as magical as the virtuous brother said." ”

Su You couldn't help but be a little embarrassed: "In the end, it's still the senior brother who is well cultivated, just now I lost my temper." ”

After speaking, he rolled up his sleeves: "Let's try!" ”

Strictly speaking, this also requires the calculation of the magnetic flux, and then the number of coil turns is determined according to the wire diameter and resistance of the enameled wire, but now it is only a principle test, and there is no need to be so fine.

Soon Su oil wrapped twelve coils, wrapped them in wax paper and stuck them in the stator slot, and then began to connect the joints of the coils to make the stator of the three-phase motor.

After that, the lacquer is dipped, baked, the enameled wire is hardened, and then the magnet rotor is inserted.

With the same principle, Zhang Tianshi led his own scientific research team to imitate Su You's practice and make another one.

Add the housing and place the two motors at opposite ends of the lab table to connect the electrodes.

A pulley is attached to one motor shaft and a fan blade is attached to the other motor shaft.

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

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

"Hahahaha!" Zhang Tianshi stroked the table and laughed: "My brother is really a heavenly man!" It really happened. ”

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

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

"With this equipment, we are able to generate electricity from mechanical energy. The electrical energy is then transmitted to other places and used as an input source for mechanical power. ”

Zhang Tianshi nodded: "Wonderful, for example, the number of lozenges prepared by the Shifu today is huge, and the medicine shop is set up next to the watermill room, and the medicine is easy to get damp, and it is set on the side of the boiler, but it is smoky and burning, which affects the medicinal properties." ”

"Wind workshops are useful, but they are affected by the weather. It is even more troublesome to use animal power to raise livestock. ”

"With this set of equipment, we can make medicine far away from the river boiler, not bad! Brother Xian really has a heart! ”

Belch...... Senior brother, I'm afraid there is some misunderstanding......
