The so-called AOD furnace is to blow oxygen into the molten steel at the same time as the standard atmospheric pressure when refining stainless steel, and to achieve the effect of false vacuum by reducing the partial pressure of CO, so as to reduce the carbon content to a very low level, and inhibit the oxidation of chromium in the steel.

"Then we'll import one!"

Liu Lang said on the side.

"It is necessary to import one, as long as there is a physical object, we can imitate it for him, but this needs to be carried out by the national foreign trade department, more importantly, although this stainless steel smelting technology is very common in foreign industries, it is still a state secret, the normal export list is not allowed to be included, it is not easy to buy, it seems that we can only slowly grope for ourselves to make it for him!"

Xiong Huaizhi is very familiar with this aspect, and in recent years, he has often corresponded with former colleagues abroad, and he is very familiar with various technologies.

"This ...... Besides, I'll have time to contact the Huo family on Hong Kong Island to see if they have any channels!"

Liu Lang said.

"In addition, many parts of the air conditioning compressor are millimeter level, at this level, the accuracy of our lathe is obviously not enough, this can be upgraded, barely poured, but the problem is that the strength of our tools can not keep up with the millimeter level, for example, the punching and forging of these parts requires a drill bit with a diameter of five millimeters, and the strength of such a drill bit can be improved by several levels compared with a drill bit with a diameter of one centimeter, this technology is a difficult point, and it is by no means a year and a half to overcome!"

Xiong Huaizhi listed the technical difficulties one by one, and Liu Lang was a little deflated when he heard it.

I thought it had solved the design problem, but now there are more problems in materials and accuracy, this is just the simplest air conditioning compressor, the difficulty is less than the car engine, I don't know how much, such a "simple goods" are difficult, and talk about others?

"Hehe, Liu Lang, do you feel a little discouraged?"

Xiong Huaizhi saw that Liu Lang was a little depressed.

"Well, it's a little, professor, the technology of our laboratory is also the most advanced in the country, but even so, we can't build a civilian air conditioning compressor, let alone those more advanced machinery, which makes me a little angry!"

Liu Lang shook his head and said.

"Haha, Xiao Liu Lang, how old are you, although you are extremely smart, but there are still too few things encountered, when New China was just established, the country was poor and white, not to mention the electric furnace smelting stainless steel, even the blast furnace for smelting ordinary steel can not be developed by itself, but the result?

However, in two or three years, our steel output has reached an annual output of 5 million tons, and what a change is this? Do you know why? It is because there is a group of technicians who are not afraid of hardship, tiredness, or even death. There is no one in this world who can't get the machine, only the waste people who don't want to get it, as long as we have the belief of this industrial power in our hearts, our country will definitely become strong again!"

"Well said, well said!"

Chen Chunsheng said excitedly and loudly, and the others couldn't help but applaud, and several professors in their fifties even had tears in their eyes, and they all remembered the passionate years back then.

"Professor, you're right, I'm too anxious, our country has a weak foundation and little technology, but this is only temporary, as long as we don't give up, don't lose heart, and don't forget our original intention, there will be a day when all problems will be solved, and then it will be when our country is really strong, which I believe will come after all!"

"That's right, it's not forgetting the original intention, keeping in mind the mission of our people, and all of us must always keep it in mind, you know?"

Xiong Huaizhi said to everyone.

"Rest assured, professor, we will not forget, never forget!"

Everyone replied loudly, with firmness in their voices.

With fighting spirit, everyone is full of energy, and even if there are many difficulties, they can't stop it.

Time flies, in a blink of an eye it has been the middle of May, after a month of production, more than 2,000 sets of Transformers have been produced, these robots have been painted with colors, put into a cardboard box, and then transported to the train by special personnel escorted to Guangdong Province, the people of the fire family are waiting in Guangdong Province, after receiving the goods and then transported to Hong Kong Island, they will be sent to the United States after packaging

The first draft of the first volume of the animation book of Shengtang culture has also been completed, with a total of 50 pages of full-color on 16 sheets of paper, and the painting is very exquisite, even Liu Lang can't put it down, and the cost of this animation book alone will cost more than two yuan.

You must know that the price of a black-and-white cartoon is only two cents and one, and a sixteen-page black-and-white children's pictorial is four cents and five, which is the price, and the cost is even lower, and Liu Lang's animation book costs four or five times as much as theirs.

Only the cost is high, because Liu Lang's animation books are all color, and now the only places in the country that can print color picture books are those large state-owned printing houses, and all color photocopiers are imported through the national foreign trade department, and these places are specially printed books for schools, if it were not for the relationship of Mu Xiaohu, it would be very difficult to print these books alone.

The cost is two yuan, Liu Lang directly priced six dollars, almost thirty yuan, the profit reached more than ten times, according to the fifty percent profit, he earned twelve or thirteen yuan by selling one, and 10,000 books is 1230,000 yuan, such a high rate of return is simply unimaginable.

The first batch of animated books printed 100 copies, these are all masters, the text on them is all in English, Yongli Group helped to handle the issue number, Sun Mingren specially ran over to personally escort these masters to Hong Kong Island, he is going to print 10,000 copies first, and then sell them with the toy models of Transformers.

For Liu Lang, these things are just to make some money at this stage, and the most important thing for him is to study in the laboratory.

Xiong Huaizhi is an old expert who has studied abroad, Chen Chunsheng is also a national first-class professor, it can be said that the academic level of the two of them has been at the top level in China, can follow the two of them to learn, that is not the opportunity that anyone has, Liu Lang will certainly not let go, every day in addition to class is soaked in the laboratory, he is weak, the strength to work can not move, but his thinking ability is too strong, understanding is also very people can compare, encounter any questions immediately ask, more than a month to learn more knowledge than in a year in books, for this Chen Chunsheng sighed again and again, said Liu Lang's comprehension and learning ability has arrivedIn the realm of "otherworldly", if he continues to study like this, he is afraid that it will not take a year to hollow out the knowledge he has learned for half of his life, but he is very happy, and it is a blessing for the country to have such a talent.

During this period, Cui Jun and Ye Jinsheng found Liu Lang once, Ye Jinsheng was obviously very happy, he made a batch of tapes, and the sale effect was very good, and more than 50,000 tapes were sold at one time, each tape cost two yuan, a total of more than 100,000 yuan, and the net income was more than 80,000 yuan.

Of course, Liu Lang had to accept the money for nothing, and this time he became a 10,000 yuan household.

Ye Jinsheng, who made seventy or eighty thousand at once, was also very excited, he said that these tapes were very sought-after, so he had to take advantage of the victory to pursue, the second and third batches of tapes were already in the process of being made, and it seemed that he could sell hundreds of thousands of sets, and he might become a millionaire by then.

"Brother Ye, you have to release the tape as soon 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 tapes are selling so well that a lot of people who didn't buy them went to the store to ask. ”

Ye Jinsheng was a little puzzled.

Of course, Liu Lang knows the reason, I am afraid that each of the songs on this tape will become a popular track in the next few years, but as soon as this tape comes out, I am afraid that countless people will imitate it, and the ability of Chinese people to fake is unparalleled in the world, even after more than 20 years, it has not been solved.

"Brother Ye, the technology of this tape is not an advanced technology, basically it can be made for thousands of dollars, if someone takes your tape to rip, I'm afraid it won't take much time, the tapes of these songs will be all over the street, you have to do more now while those people don't react, wait until those people react, hehe.........!"

Liu Lang's words made Ye Jinsheng react.

"This ......... Liu Lang, if that's the case, your income will also be reduced, so we have to find a way?"

Ye Jinsheng was a little anxious.

"If anyone dares to rip it, we will sue him, and they will lose this lawsuit!"

Cui Jun said on the side, he didn't know anything about his original music in this tape, this song cost him too much attention, and if it was sold for money by others, he would lose a lot.

Who has so much time to go to court, besides, now the country does not have a corresponding property rights protection law, we have to hold on, so the most important thing now is to hurry up and sell as many tapes as possible, only in this way can we reduce losses!"

Not to mention a few tapes, more than 20 years later, those famous foreign brands have been modified by domestic manufacturers and sold for money.

"That......... Damn, let's get back!"

Ye Jinsheng didn't say anything more to Liu Lang, he got up and left with Cui Jun, he was going back to record the tape quickly.

"Alas, that's the case without legal protection, there's no way!"

Even if Liu Lang is extremely smart, there is nothing he can do about piracy.
