The so-called AOD furnace is to refining stainless steel by blowing inert gas while blowing oxygen into the molten steel under standard atmospheric pressure. By reducing the CO partial pressure, a false vacuum effect is achieved, thereby reducing the carbon content to a very low level.
And it inhibits the oxidation of chromium in steel. This technology has been widely used in the West. It is not a strange technology, but it has not been seen in China.
"Then we will import one!"
Liu Lang said from the side.
"We have to import one. As long as we have the actual product, we can imitate it. However, this requires the national foreign trade department. More importantly, although this stainless steel smelting technology is very common in foreign industries, it is still
It belongs to the category of state secrets and is not allowed to be included in the normal export list. It is not easy to buy it. It seems that we can only slowly explore and make it ourselves!"
Xiong Huaizhi is very familiar with this aspect. In recent years, he has often corresponded with his former colleagues abroad and is very familiar with various technologies.
"Let's talk about this... I'll contact the Huo family on Hong Kong Island when I have time to see if they have any channels!"
Liu Lang said.
"In addition, many parts of the air-conditioning compressor are at the millimeter level. At this level, the accuracy of our lathes is obviously not enough. This can be upgraded and modified, and it can be done barely. But the problem is that the strength of our tools is at the millimeter level.
At the same level, it cannot keep up. For example, the drilling and forging of these parts requires a drill bit with a diameter of five millimeters. The strength of such a drill bit can be several levels higher than that of a drill bit with a diameter of one centimeter. This technology is a difficult point and will definitely not take a year.
It can be conquered in half a year!"
Xiong Huaizhi listed the technical difficulties one by one, and Liu Lang felt a little discouraged.
I originally thought that the design problem was solved, but now more problems have arisen in terms of materials and accuracy. This is just the simplest air-conditioning compressor. It is much less difficult than a car engine. Such a "simple product" is full of difficulties.
, talk about other things?
"Haha, Liu Lang, do you feel a little discouraged?"
Xiong Huaizhi saw that Liu Lang was a little depressed.
"Well, it's a bit. Professor, the technology in our laboratory is the most advanced in the country, but even so, we can't build a civilian air-conditioning compressor, let alone those more advanced machines. This makes
I'm a little angry!"
Liu Lang shook his head and said.
"Haha, Xiao Liu Lang, how old are you? Although you are extremely smart, you still encountered too few things. At that time, New China was just founded and the country was very poor. Not to mention the electric furnace that could smelt stainless steel, even the blast furnace that could smelt ordinary steel could not
Develop it yourself, but what’s the result?
Within two or three years, our steel output reached five million tons per year. What a big change is this? Do you know why? It is because of a group of technicians who are not afraid of hardship, fatigue, or even death.
As long as we have them, nuclear bombs will be built and satellites will be launched into the sky.
, these things can be made for him, stainless steel and compressors are nothing! There is no machine in this world that no one can make, only useless people who don’t want to make it. As long as we people have the belief in this industrial power in our hearts, our
The country will definitely become stronger again!"
"Well said, well said!"
Chen Chunsheng said excitedly and loudly, and others couldn't help but applaud. Some professors in their fifties even had tears in their eyes. They all thought of the passionate years back then.
"Professor, you are right. I am too impatient. Our country has a weak foundation and few technologies, but this is only temporary. As long as we people don't give up, don't lose heart, and don't forget our original intention, there will be a day when all the difficulties will come.
Everything will be solved, and then our country will be truly strong, and I believe this will eventually come!"
"That's right, it's about not forgetting your original intention and keeping in mind the mission of us people. All of us must always remember it, you know?"
Xiong Huaizhi said to everyone.
"Don't worry, Professor, we will not forget, we will never forget!"
Everyone answered loudly, with firmness in their voices.
With fighting spirit, everyone is full of energy and cannot be stopped even if difficulties and difficulties arise.
Time flies, and it is mid-May in the blink of an eye. After a month of production, more than two thousand sets of Transformers have been produced. These robots are painted with colors, put into cartons, and then transported to the train.
Specialized personnel escorted them to Guangdong Province. People from the Huo family were waiting in Guangdong Province. After receiving the goods, they were transported to Hong Kong Island, where they were packaged and sent to the United States.
The first draft of the animated book of Shengtang Culture has also been completed. It has 50 full-color pages in 16 pages. The paintings are so exquisite that even Liu Lang couldn't put it down. The cost of this animated book alone is more than 2 yuan.
money.
You must know that a black-and-white cartoon costs only 21 cents, and a 16-karat black and white children's illustrated magazine costs 45 cents. These are both selling prices, and the cost is even lower. And Liu Lang's animation book costs just 45 cents.
Four or five times theirs.
The reason why the cost is high is because Liu Lang's animation books are all in color. Now the only places in the country that can print color picture books are those large state-owned printing plants. Color copying machines are all imported through the national foreign trade department. These places specialize in printing color picture books.
The school prints books. If it weren't for Mu Xiaohu's relationship, just printing these books would be very difficult.
The cost is two yuan. Liu Lang directly priced it at six dollars, which is almost thirty yuan in RMB. The profit reached more than ten times. Based on the 50% profit, he would earn twelve or three yuan from selling one copy, and ten thousand copies would be ten.
Twenty to thirty thousand, such a high rate of return is simply unimaginable.
The first batch of animation books was printed in 100 copies. These are master copies, and the text on them is all in English. Yongli Group helped handle the issue number. Sun Mingren specially came over to personally escort these master copies to Hong Kong Island. He was going to first
Ten thousand copies will be printed and will be sold together with Transformers toy models.
For Liu Lang, these things are just a way to make some money at this stage. The most important thing for him is to study in the laboratory.
Xiong Huaizhi is an old expert who has studied abroad, and Chen Chunsheng is also a national first-class professor. It can be said that the academic level of the two of them is already at the top level in the country. It is not a chance for anyone to study with them.
Of course, Liu Lang would not let it go. In addition to going to class every day, he spent time in the laboratory. He was weak and couldn't do the work, but his thinking ability was too strong and his understanding was very human.
To compare, if you encounter any questions, ask them immediately. You can learn more knowledge in more than a month than from books in a year. For this reason, Chen Chunsheng repeatedly lamented, saying that Liu Lang's ability to understand and learn has reached the level.
He was in an "otherworldly" realm. If he continued to study like this, he was afraid that half of his lifetime knowledge would be wiped out in less than a year. However, he was very happy. It was a blessing for the country to have such talents.
During this period, Cui Jun and Ye Jinsheng visited Liu Lang once. Ye Jinsheng was obviously very happy. He produced a batch of tapes and the sales went very well. More than 50,000 tapes were sold at one time. Each tape sold for two yuan, and the total price was two yuan.
He paid more than 100,000 yuan, and the net income was more than 80,000 yuan. According to regulations, Liu Lang could get 10% of the profit, which was 8,000 yuan. However, in order to please Liu Lang, Ye Jinsheng spent 10,000 yuan.
Of course Liu Lang had to accept the free money, and now he became a household worth ten thousand yuan.
Ye Jinsheng was also very excited after making 70,000 to 80,000 yuan at once. He said that these tapes were very popular, so he had to pursue the victory. The second and third batches of tapes were already in the process of being produced. It looked like they could sell hundreds of thousands of sets. By then,
He may become a millionaire.
"Brother Ye, you have to release the tape as quickly as possible. The sooner the better. If it's late, I'm afraid you won't make much money!"
Liu Lang said bluntly.
"Oh, why? Our tape sells very well, and many people who haven't bought it have gone to the store to ask."
Ye Jinsheng was a little puzzled.
Of course Liu Lang knew the reason. I am afraid that every song on this tape will become a popular track in the next few years. However, as soon as this tape comes out, countless people will probably imitate it. The ability of Chinese people to fake is unparalleled in the world.
It has not been resolved after many years.
"Brother Ye, the technology of this tape is not advanced. You can basically make it with a few thousand yuan. If someone takes your tape and rips it, it won't take long for tapes of these songs to be all over the streets.
That's right, you have to do more now while those people don't react, and wait until those people react, haha...!"
Ye Jinsheng reacted to Liu Lang's words.
"How...how can this work? Liu Lang, if that happens, your income will also be reduced. We have to find a way?"
Ye Jinsheng was a little anxious.
"If anyone dares to copy it, we will sue him and they will definitely lose the case!"
Cui Jun said from the side that there was an original piece of music in this tape that he knew nothing about. This song cost him too much effort. If others took it and sold it for free, he would suffer a big loss.
"Two of you, you can sue one or two. If ten or eight of them suddenly come out, where can we sue? Who has so much time to file a lawsuit? Besides, the country does not yet have a corresponding property rights protection law, so we have to
Hold on, so the most important thing now is to quickly release the tapes and sell the most tapes in the fastest time. Only in this way can losses be reduced!"
Not to mention a few tapes, more than 20 years later, even those famous foreign brands were used by domestic manufacturers to modify them and sell them for money.
"Then... damn, let's go back quickly!"
Ye Jinsheng didn't talk to Liu Lang anymore, got up and left with Cui Jun. He wanted to go back and record the tape quickly.
"Oh, it's like this without legal protection, there's nothing we can do!"
Even Liu Lang, who is extremely smart, can't do anything about piracy.
