"Carbon steel...Is there any possibility of improving its quality?"Mr. Hou did not say a word throughout the whole process. Now that he spoke, he realized that his question was a bit general and involved too many aspects, so he had to refine it: "I mean, its hardnessand various aspects can be improved.""It is now...very strong and can be used in many fields, but it does not mean that it has no room for improvement. If it improves, I believe its application fields will be more." Mr. Hou said meaningfully."...You mean the large-scale application in the aerospace field?"Zhang Heng asked back, and there was a reason for asking this. He smiled and said: "The latest news is that the Star-Spangled Empire has built a huge rocket, and its rocket body is made of high-strength stainless steel, that is, special steel.""It seems...you are very concerned about many international news." Mr. Hou answered irrelevantly, but he nodded gently while speaking, which explained everything."It still has room for improvement, there is no doubt about that."Zhang Heng pondered for a moment, and gave a reply after careful consideration: "I am also conducting relevant research, but the current conditions are very limited.My experiments are all on some simple instruments, and there are many things missing, so many things actually only exist in theory."Before he finished, he pointed to his head, as if to say that many theories were in his mind, but he could not experiment because of the lack of instruments and research institutes: "Iron and steel have been used on a large scale since ancient times, and the reserves of iron ore are the largest in the world.I always believe that it still has a lot of potential to be tapped. "Look forward to your results!"Mr.Hou said this not out of courtesy, but really optimistic about the young man in front of him. "I will!"Zhang Heng responded shyly, but his eyes were full of seriousness, indicating that he listened and did what he said, and would tap the potential of steel.Some people couldn't wait.Without any greeting, they ran into the warehouse and walked around, touching the piled, very cold carbon steel from time to time.More than half of the people are engaged in research related to materials. Good materials are their favorites. In a sense, these carbon steels are more valuable than gold in their hearts.Without professional instruments, it is impossible to (abcj) verify it.Is it really super high quality carbon steel? No one knows, but they believe Zhang Heng would not lie to them, and they believed that the people of China Shipbuilding Group were not fools.After shipping back, they would definitely conduct random inspections.They took a good walk around, but time was limited, so they finally left reluctantly.Next stop!Warehouse No. 3 was not far away, just across a road, just a few steps to the side."DEF!""DEF!"This time they took a breath of cold air. They had not noticed before, and it was also blocked by many wooden boxes.When they walked past the area where the wooden boxes were placed, they found that this large warehouse that looked like a fuel production line had a lot of treasures behind it."Crude oil residue?""Yes, it is the residue after crude oil is refined!"Zhang Heng gave a positive answer, but he could not give an accurate data: "These residues have been accumulated for a period of time, and there are many kinds of substances in them. At least, I only extracted oil substances, and did not extract other substances.""Of course, more substances may be extracted later, such as asphalt. The roads in our group's industrial plant have not been built yet. In the future, asphalt can be extracted for paving." Zhang Heng said."Mr. Zhang, I am afraid that the subsequent treatment is also to sell the residues, right? I have some connections with the two domestic oil groups. Can I help you to connect and build a bridge?""Yes, the value of these residues is not low. Everyone knows that crude oil is a gem. The main one is fuel oil, but the remaining residues are also treasures."I don't know who started it first. Everyone talked about the crude oil residues without saying a word."I did dispose of it accurately, but it will take some time to accumulate. It's not a bad idea to dispose of it all at once!"Zhang Heng had planned to sell crude oil residues.The current amount is already quite a lot, occupying two-thirds of the warehouse area, but it doesn't mean it's a lot.He didn't ask Smart No. 1 about the amount.He just wanted to accumulate it and wait and see whether he would need to refine the material in the future: "The research on crude oil residues has been going on internationally.I am also interested in this aspect.""Apart from anything else, the latest research shows that after many rounds of refining, crude oil residues have no much refining value, but scientists have extracted a lot of things from it, such as high-strength carbon fiber, which has turned waste into treasure."Zhang Heng said the truth, and I believe many people present knew this."Do you have any ideas in this regard?" Hou Lao was no longer calm [his eyes lit up.Carbon fiber!But it's an extraordinary thing, and the threshold is not so high now. A few decades ago, there was a blank in China, resulting in the need to import from abroad at high prices, especially from the island countries. I don't know how much money the islanders made.The Japanese sell it at a very high price. Generally speaking, if it is not a very high-strength carbon fiber, they dare to ask you for millions or tens of millions per ton, and they will not sell you high-strength carbon fiber no matter how much you ask.It was only after China invested a lot of research more than 20 years ago and made some breakthroughs that the gap was filled. However, even so, more than two-thirds of the domestic carbon fiber market is imported, and only one-third is domestically produced.Moreover, domestically produced carbon fiber is only of general, highest to medium strength, and high-strength is still rare.Therefore, the value of high-strength fiber is not cheap now. One ton is more than one million, and some relatively better ones are five or six million yuan per ton.As for ultra-high-strength ones, they are all included in strategic resources. Let alone export, they don't even quote you the price, which has already shown that they will not sell it no matter how much money you pay.If ultra-high-strength carbon fiber is made and sold normally, and one ton is quoted at 10 million, it is guaranteed that many institutions will buy it without blinking an eye, and the more the better.Okay!15 million per ton is within the acceptable range at normal prices.If a ton costs 20 million, some people will think it is too expensive, but they will buy it if they need it.If a ton costs 25 million, people will scold you for being too ruthless, but they may still bear the pain and pay the money.If a ton costs 30 million, people will probably get angry.But no matter what, when a material is strong to a certain extent, its price is beyond your imagination. In tons, the price of a ton may double, which seems unrealistic, but it is the reality, and there is nothing to dispute.
