Everyone set off early in the morning, ate casually in the restaurant and then withdrew non-stop. The pen "Fun" Pavilion www.biquge.info go back at high speed, and it must be afternoon when I arrive, and I must have eaten in the evening.

When we set off, it finally rained, and it was really autumn rain. Rain means cold, but the weather doesn't interfere with driving.

Star fruit sneezed, and her body vibrate.

"What's wrong? Did you catch a cold? Da Ming said with concern.

"Nothing suddenly a shiver." That being said, the sneeze would not be a hint. Could it be that someone said that played her? Or do you have to wait until you go back and face bad things, such as a blast furnace accident that is far worse than what was said on the phone?

Along the way, the star fruit was a little worried, but Da Ming on the side couldn't see the abnormality. Hehe, it's really a worrying person who is comfortable, but he, a comforter, is worried.

Da Ming bored and took out his big brother. "This thing just can't be used for power, it has to be charged every day, and I really don't know when a good battery will be invented."

"Yes. If my brother is willing, we can go back and study it a little. ”

Ma Hongjun, the co-pilot, turned his head: "Does my little designer have any ideas again?" ”

Da Ming and Ma Hongjun were both looking at themselves, and star fruit said: "I think my brother's big brother should also be eliminated, and I chatted with Mr. Paul in the United States for a while, didn't he say that there are many novelties on the other side of the ocean?" I think there must be a very good battery over there, and he told me that the United States is using lithium batteries, and even uses this thing to drive cars. I just thought......"

Da Ming suddenly came to the spirit, and my sister must have a new idea. "Go on!"

Two months later, 1995 was the year when the small phone went on sale, and the Windows 95 system was also on sale. From this year on, star fruit felt that the world she was familiar with had finally arrived, and when the time came, she bought a computer and connected to the Internet. The thought of this excites my heart.

"What's fun?" Da Ming asked.

Well, they were still waiting for a reply, and the star fruit suddenly said: "The battery is not good because it is a manganese battery, and now it is a lithium battery." This lithium battery can be recharged, and the power is also large, but the production cost is a bit high. Anyway, now that we have money, don't we also have a bunch of college students under us, if we are willing to invest, we will definitely be able to produce it, and then my brother's big brother will not have to always recharge. ”

Da Ming laughed, thinking that his sister was going to make something again, and the battery that he worked so hard to make was for himself. But his sister's smile is very intriguing, he knows that there must be something deep in it, and star fruit is not to be said.

Star fruit has a deep idea, and it can't get into home appliance manufacturing in the future. The production of batteries is more complicated, if it is successful, it must produce lead-acid batteries and lithium batteries in large quantities.

In later generations, some people ridiculed that the nineties were the era of motorcycles, and later motorcycles were eliminated by electric vehicles, and the first people to ride motorcycles died in traffic accidents. In fact, the real reason is that electric vehicles are moderately priced, have enough power, and most importantly, do not need a license plate. There must be businesses that produce lead-acid batteries in China, and this is already available as a power supply for electric vehicles. The lithium battery is to be used as a special power supply for electric vehicles, that is, balance cars.

I don't know when the gyroscope promised by Paul will arrive, as long as the gyroscope and lithium battery are done, the key organs of the balance bike will be completed. A new round of scientific and technological revolution has taken place, and we must seize this opportunity in order for new technologies to be born in a steady stream.

Now that she has a unique convenience, now that she thinks about it, the production task for which she has suddenly become nervous. To cast agricultural machinery, the production of automated steel ball production lines, small hardware and household appliances can not be abandoned, and now electric vehicles are on the agenda. Alas, it's tiring to be an engineer.

When I finally arrived home in the evening, the star fruit didn't care about anything else for the time being, and walked directly into the factory with the Daming Ma Red Army.

A shattered blast furnace unfolded, completely scrapped.

"You came back in time, this stove was thrilling when something happened!" It was actually Zhong Haokai who said this. Isn't this one going to have to wait a while to come back? Carambola and Daming reported the same question.

Zhong Haokai waved his hand and said don't mention it, and then talked about the front and back of the blast furnace accident. It turned out that Zhong Haokai completed the task perfectly this time, a batch of goods were delivered to the hands of Russian businessmen, and successfully exchanged for five Russian lathes, and under the strong request of Russian businessmen, some broken copper and iron were pulled back.

"So I thought, it's all scrap iron anyway, Lao Maozi is sold at the price of cabbage, of course we have to buy it, and it's much cheaper to come back to the furnace than to buy a steel mill." Who knows that this thing is really dry burned, and what should it be like if it is burned red, but as a result, the temperature will be increased, and the furnace will be burned. ”

When Zhong Haokai said this, the old man Liang on the side was a little timid, and he gave the order to add warmth, and he ignored the concerns of the borrowed steel mill workers. People are old and stubborn, and Old Man Liang is just angry, why can't this thing be burned?

Carambola thought about what could not be melted, what did Brother Zhong pull back. As a result, Zhong Haokai pointed to a corner of the factory: "It's those scrap irons, it's really evil." ”

Carambola and Da Ming walked up curiously, shocked by what they saw. "Brother, do you know what these things are! How can I look at the stuff and think that the tracks of the tank have load-bearing wheels?

"What? Tank! Da Ming squatted down and fiddled, as if he did have a track, and he could still put it together.

These military objects are also made of steel, and it stands to reason that they should be able to be burned, but the blast furnace is finished. Da Ming and Zhong Haokai don't seem to understand these things, but star fruit does. "Brother, this thing can't be made of manganese steel."

Although Daming also learned a lot of metal knowledge, it was all civilian. Since there is no contact with military weapons, it is reasonable not to know the physical properties of these special steels.

Manganese steel is tank steel, and when manganese is added, it has a high melting point, and this alloy is particularly strong and meets tactical requirements. The temperature of iron smelting could not burn this alloy at all, and in this case the blast furnace accident was almost the first melting of the refractory, and then the blast furnace shell. "Uncle, our blast furnace can only practice crude steel." Star fruit asked a steelworker.

She got an accurate answer, and sure enough, this blast furnace was an accident and an accident caused by adventure. "If our country had 3,000-degree refractory bricks, then everything could be smelted." Star fruit said intriguingly.

China's smelting technology is inferior to the United States, just say that this aircraft carrier steel, the United States' technology is powerful, of course, many years later, China stole the even, and this technical information has been secretly seen by star fruit, the formula and processing technology she still remembers. Secondly, smelting good steel requires a refractory material that is particularly resistant to high temperatures, and fortunately, the refractory material star fruit of 3,000 degrees is the same as knowing.

The secret couldn't be revealed yet, and she didn't want to be the target of public criticism.

"There's no way, if you sell these scrap irons, I guess the steelworks don't want it." Da Ming said helplessly.

"Don't! It's gold that shines sooner or later. Let's wait until we buy a blast furnace and smelt them. ”

Star fruit also admires Zhong Haokai very much, this thing is really bold, these scrap iron are estimated to come from a batch of disintegrated tanks. The legacy of the Soviet Union, such as a large number of discarded military weapons, which were placed and slowly decayed, and being able to transport these things back also proves that Zhong Haokai is very capable, and I really don't know what others have experienced in Manchuria.

The matter of the blast furnace was put on hold for the time being, and just now I heard Zhong Haokai say that the lathe of the Soviet Union was also shipped back, and his curiosity immediately came here, and he took Daming's hand and changed the workshop.
