    "Commander, Political Commissar Zhang is here!" "Got it!" Guan Fei put down the phone, walked to the window, and watched Zhang Shengguo's electric off-road vehicle drive into the gate of the military headquarters and stop in front of the building.  Yu Baihai and Luo Zhenying drove the test vehicle around several military regions of the Kuomintang. The experiment was a great success. During the long-distance driving of more than a thousand kilometers, there were only one or two minor failures, which were quickly eliminated.  After arriving, Guan Fei received feedback from the accompanying technicians, made minor corrections to the faults, and officially started small-scale trial production.  Electric vehicles are much simpler than fuel vehicles. There are no complex gearboxes, transmission mechanisms, or motors. There are at least 60% fewer parts, mainly the key components of the car casing, motor, and battery.  , even with an imperfect manufacturing industry chain in the base area, it can be easily manufactured.  Now, of the first batch of 200 military vehicles, except for 20 vehicles allocated to high-level officials such as Guan Fei and Zhang Shengguo, all others have been allocated to the troops to obtain further feedback on use.  After half a year of data collection is completed, the last modification will be made. The next step is to finalize the shape, set up a production line and start large-scale production.  Immediately afterwards, civilian models will also be launched one after another to meet the office and living needs of various departments, units, and ordinary people.  The difference between the military version and the civilian version is the battery.  The military model uses safe lithium batteries, which is a secret technology only available in the base area.  It uses graphite to store lithium atoms, so even if the battery shell breaks and air enters the inside of the battery, the oxygen atoms will be too large to enter the fine grid on the graphite surface and react with the lithium atoms, causing an explosion.  ?The civilian version uses reinforced sealed lead-acid batteries to reduce costs.  In order to reduce the weight of the car body, extensive use of composite carbon fiber and aluminum alloy has reduced the body of an ordinary four-door electric vehicle to about 800 kilograms.  It can travel for five hours on a single charge. The maximum altitude is only 60 kilometers, and the maximum driving range is about 200 kilometers. In terms of performance, it is not very good and can barely be used.  However, the price of the civilian model is very cheap. A standard four-door model only costs more than 7,000 yuan. The savings of an average family in about three years are enough to buy one. It is very convenient for family outings or commuting to and from get off work.  The biggest problem in making electric vehicles practical is charging.  Therefore, both electric vehicles use fast charging technology, which can charge about 60% of the electric energy in only a quarter of an hour.  In this way, when the power is used up, the electric vehicle can continue to drive by charging it in a short time.  In order to ensure that people can charge at any time, 10,000 charging piles have been installed in various units, roads, preset parking lots and other places in the new city for use.  Anyway, the base area has sufficient electricity. In addition to the 1.2 billion thermal power station in Kunming, a series of hydropower stations will be built on the Salween River. By then, there will be too much power to use.  Rather than wasting it in vain, it is better to encourage people to use more household appliances to consume excess electricity.  "Good old Guan, sit tight on the Diaoyutai." Zhang Shengguo pushed the door open and came in. He looked at Guan Fei, who was sitting on the sofa with his legs crossed, and said with a smile.  "Sit down, why don't you make a call and go in person?" Guan Fei smiled, stood up, made a new cup of tea for him and himself, put it on the water coaster on the coffee table, and asked.  "It's about our joint venture with the domestic military to set up a factory. There's some trouble. I couldn't explain it clearly on the phone." Zhang Shengguo waved the secretary and others out, and then said seriously, "Our cooperation project with the country is not going smoothly.  "Yeah." "What do you say? Don't worry, speak slowly." Guan Fei raised his eyebrows and stared at the other party, waiting for his explanation.  "The problems are multifaceted." Zhang Shengguo frowned into a Sichuan shape and sighed, "Originally we thought about cooperating with the country, firstly to alleviate our manpower shortage, and secondly to help the military make some money and win  Their favor can, thirdly, satisfy our growing appetite for production materials, and fourthly, it can also enrich domestic demand for material products. It seems to be a good thing that achieves multiple goals with one stone. However, in practice, there are many problems, such as some in China.  The veteran cadres were very dissatisfied with this, saying that mineral mining was a national matter, and the investment company we established with the military was not justified and it was not appropriate to get involved. The Ministry of Mining probably did not want its power to be taken away, and it firmly disagreed with us.  Mining means that we can engage in smelting, but we cannot directly contract the mines and mine them ourselves. Then there are various rules and regulations and planning arrangements. In short, they are just trying to mess up the matter. " "Then how do we sell the ores?  To us?" Guan Fei said in surprise.  "Yes, they sell us concentrated ore powder. But I asked, and they don't sell the good concentrated ore powder at all. They only give us the worst and difficult-to-refining ones. For example, iron ore, they are willing to sell it to us.  It is the fine powder of Panzhihua. It contains not only iron, but also titanium,There are a lot of messy ingredients such as magnets, chromium, scandium, cobalt, and nickel, and Panzhihua herself has a hard time refining them.  I learned that if they mine 10 million tons of ore a year, they can produce more than 2 million tons of titanium-containing steel. Among the more than 3 million tons of slag that is thrown away, there is still more than 20% of titanium.  If you can't refine it, just throw it by the river." Guan Fei nodded: "Vanadium titanium magnetite is indeed difficult to refine.  Titanium has a high melting point and is easily mixed with several other elements with high melting points during blast furnace smelting.  And when it spreads, the furnace will become more and more solidified, making it impossible to stir, resulting in the inability to produce molten iron.  Iron in Panzhihua was discovered in the 1930s, and the country went for prospecting again in the 1950s. The proven reserves at that time were 8 billion tons. The country was overjoyed, thinking that a huge mine had been discovered.  The result is that it has been unable to be used because it is difficult to separate. Foreign countries even say that it is a useless and dull mine.  China has been researching for more than ten years before finally finding a way to make steel. However, the large amount of titanium in it cannot be used and can only be thrown aside with blast furnace slag.  " "You know very well!  Zhang Shengguo glanced at him in surprise, "I listened to Minister Luo talking on the phone for a long time before I could barely understand it. If I had known better, I would have asked him to call you directly."  " Guan Fei smiled, leaned in the sand, folded his hands on his chest, and fell into deep thought. Panzhihua's vanadium-titanium magnetite is currently incapable of smelting due to technical reasons. This unique mineral deposit has resulted in no foreign reference in the country.  He could only study this topic step by step. It took decades. Based on the information stored in the biological assistant brain, he knew how long it took to overcome this difficulty in China and how much effort was made.  , I have thought of many ways, done many experiments, and I know the final solution. However, this is only a rough framework and there is no complete solution. This is not a matter of coming up with one or two sets of equipment, but involves very much.  Complex and precise process flow. Even with the database in Biological Vice Brain, he only confirmed the corresponding research direction and specific implementation methods. However, the relevant process flow and process requirements also require continuous attempts and cannot be solved immediately.  It was solved. Zhang Shengguo saw that he was deep in thought and did not disturb him. He quietly waited for him to wake up with a glass of water. "This mine can be mined. I think I can try it."  "Guan Fei thought about it and finally made the final decision. He no longer hesitated and said. "He knows that although the grade of Panzhihua Iron Ore is a bit low, the iron content is only more than 30%, and the associated minerals are  More, but its final reserves are not 8 billion or 10 billion, but hundreds of billions of tons! If fully exploited, it would be enough for the whole of China to smelt for thousands of years!  Not only can iron be extracted from it, but also vanadium, a strategic element that strengthens the quality of steel, and more precious titanium can be separated. No matter from which angle you look at it, the significance of conquering Panzhihua vanadium titanium magnetite is extremely significant!  Major. Previously, he had considered whether to abandon domestic ore sources and instead purchase ore from the international market, such as purchasing ore from Australia. The grade of ore in Australia is much higher than that in China, and their highest grade ore reaches 7%.  More than ten, there is no need for primary refining and sintering. The ore can be ground directly into the blast furnace and made into molten steel. The cost is much more cost-effective than using domestic ore, especially the iron ore in Panzhihua. But after thinking about it, I thought about it.  Australia's iron ore is basically monopolized by two British-owned companies, Rio Tinto and BHP Billiton. It is too difficult to extract the teeth from them. Moreover, even if you spend money to pick up the ore, the supporting facilities such as railways and ports shipped from the mining area are also limited.  It is in their hands, so they have to invest in building railways and ports themselves. If they spend so much money, if there is a dispute with the United States and they are sanctioned by the West, they may not even get a piece of iron ore.  Don¡¯t even think about shipping it from Australia. Then why bother spending so much money to help others build railways and ports? Isn¡¯t this making wedding dresses for others? From a safety perspective, it¡¯s better to use domestic ones?  Mineral sources are the most reliable! After all, the base relies on technological advantages, even if it uses slightly more expensive raw materials, because of its advantages in labor productivity, it can even out the cost gap with its competitors, including cutting-edge technology.  The advantage is that it is a little more expensive, and you are not afraid that no one will buy it. In this case, why would you put your life in the hands of others?
