"Commander, Commissar Zhang has arrived!"

"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 Command Department and stop in front of the building. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ。

Yu Baihai and Luo Zhenying drove the test car around several military regions of the People's Party, and the experiment was extremely successful, and there were only one or two minor failures during the long-distance drive of more than 1,000 kilometers, and they were quickly eliminated. After coming back, Guan Fei got the feedback from the accompanying technicians, made small corrections to the fault, and officially started small-scale trial production.

Electric vehicles are much simpler than fuel vehicles, without complex gearboxes, transmission mechanisms, and no engines, and at least 60% less parts, mainly car shells, motors, batteries, these key components, even if the base is not very perfect manufacturing industry chain, can be easily manufactured.

At present, the first batch of 200 military vehicles, except for 20 vehicles, which are allocated to Guan Fei, Zhang Shengguo and other high-level uses, are all distributed to the troops to obtain further feedback on their use.

After half a year of data collection, one last modification will be made, and the next step is to finalize the production line and start large-scale production. Immediately afterwards, civilian models will also be launched one after another to meet the office and life needs of various departments and units, as well as the general public.

The difference between the military model and the civilian version is the battery.

The military model uses a safety lithium battery, which is a secret technology that can only be found in the base. It uses graphite to store lithium atoms, so even if the battery shell is broken and air enters the inside of the battery, the oxygen atoms are too large to enter the fine grid on the graphite surface and react with the lithium atoms, causing an explosion.

The civilian version, on the other hand, uses a strongly-sealed lead-acid battery to reduce costs. In order to reduce the weight of the body, a large number of composite carbon fiber and aluminum alloy are used to reduce the body of an ordinary four-door electric vehicle to about 800 kilograms. It can drive for five hours on a single charge, the maximum speed is only 60 kilometers, and the maximum mileage is about 200 kilometers.

However, the price of the civilian type is very cheap, a four-door standard model is only more than 7,000 yuan, and the savings of the average family for about three years are enough to buy one, which is still very convenient for family travel or commuting.

The biggest problem with the practical use of electric vehicles is charging.

Therefore, both electric vehicles use fast charging technology, which can be fully charged with about 60% of the electricity in just a quarter of an hour. In this way, when the power runs out, the electric car can continue to drive after a short charge. In order to ensure that the masses 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.

In addition to the 1.2 million thermal power station in Kunming, a series of hydropower stations will be built on the Salween River, and there will be too much electricity to be used at that time. Instead of wasting in vain, it is better to encourage the masses to use more household appliances to consume excess electricity.

"Okay, you old pass, sit firmly in Diaoyutai." The door was pushed open, Zhang Shengguo pushed the door in, looked at Guan Fei who was sitting on the sofa with Erlang's legs crossed, and said with a smile.

"Sit down, what's the wrong thing you can't call, you have to run in person?" Guan Fei smiled, got up to help him and himself make a new cup of tea, put it on the coffee table and water coaster, and asked.

"It's about our joint venture with the domestic military, and it's a bit troublesome, and it's not clear on the phone." Zhang Shengguo waved his hand to let the secretary and the others go out, and then said, "Our cooperation project with China has not been carried out smoothly." ”

"How so? Don't rush, speak slowly. Guan Fei raised his eyebrows and stared at the other party intently, waiting for him to explain.

"The problem is multifaceted." Zhang Shengguo's eyebrows were twisted into a Sichuan shape, and he sighed, "Originally, we wanted to cooperate with China, first, to alleviate our shortage of manpower, second, to help the military make some money and win their favor, third, to satisfy our growing appetite for means of production, and fourth, to enrich the domestic demand for material products, which seems to be a good thing to kill multiple birds with one stone." For example, some veteran cadres in China are very dissatisfied with this, saying that the investment companies we and the military have set up are not properly named, and they should not get involved in them. The Ministry of Mines probably didn't want its power to be taken away, and resolutely disagreed with our mining, saying that we could engage in smelting, but we couldn't directly contract the mine for our own mining, and then there were all kinds of rules and regulations, and then there were plans and arrangements, in short, to make this matter worse. ”

"So how do we smelt? They sell the mine to us? Guan Fei was surprised.

"Yes, they sell us concentrate powder. But I asked, and they don't sell good concentrate powder at all, they only give us the worst and hard-to-refine ones. For example, iron ore, what they are willing to sell to us is Panzhihua's fine powder, which contains not only iron, but also titanium, vanadium, magnets, chromium, scandium, cobalt, nickel and a lot of other messy ingredients, Panzhihua itself is struggling to refine. I learned that they can smelt more than 2 million tons of titanium-containing steel by mining 10 million tons of ore a year, and more than 20 percent of the more than 3 million tons of slag they throw away cannot be refined at all, so they throw it on the riverside......"

Guan Fei nodded: "Vanadium titanomagnetite is indeed difficult to refine. Titanium has a high melting point and is easily mixed with several other elements that also have a high melting point when smelting in blast furnaces. Moreover, when it spreads, it will make the furnace more and more solidified, and it will not be able to stir it, resulting in the inability to produce molten iron. Panzhihua's iron was discovered in the thirties, and in the fifties, China went to prospect again, and the proven reserves at that time were 8 billion tons. As a result, because it is difficult to separate, it has not been able to be used, and foreign countries even say that it is a useless dull mine. It took more than ten years of research in China to find a way to make steel, but a large amount of titanium in it could not be used, so it could only be thrown aside with blast furnace slag. ”

"You know very well!" Zhang Shengguo glanced at him in surprise, "I listened to Minister Luo on the phone for a long time, and I barely figured it out, and I knew how good it would be for him to call you directly." ”

Guan Fei smiled, leaned back on the sofa, folded his hands around his chest, and fell into deep thought.

Panzhihua's vanadium titanomagnetite is now incapable of smelting, which is due to technical reasons. This unique mineral deposit has led to the inability to find foreign reference materials in China, so we can only gnaw down this topic step by step, and it took decades before and after.

According to the information stored by the biological auxiliary brain, he knows how long it took China to overcome this difficulty, how much effort has been made, how many methods he has thought of, how many experiments he has done, and he also knows the final solution.

However, this is only a rough framework after all, and there is no complete solution.

It's not a question of coming up with one or two sets of equipment, but it involves a very complex and sophisticated process. Even if he has a database in the biological vicebrain, he only confirms the corresponding research direction and specific implementation methods, but the relevant process flow and process requirements also need to be tried continuously, and it is impossible to solve them immediately.

Zhang Shengguo saw that he was pondering, and he didn't bother, holding a glass of water and quietly waiting for him to wake up.

"This mine can be refined, I think we can try it." Guan Fei thought about it, and finally made a final decision, so he no longer hesitated and spoke.

He knows that although the grade of Panzhihua iron ore is a little low, the iron content is only about 30 percent, and there are many associated ores, its final reserves are not 8 billion, nor 10 billion, but hundreds of billions of tons!

Such a large iron mine, if fully mined, is enough to make the whole of China use it for thousands of years!

At the same time, when smelting, it is not only possible to extract iron as a product, but also to separate vanadium, a strategic element that strengthens the quality of steel, and even more precious titanium!

No matter from which point of view, the significance of conquering Panzhihua vanadium titanomagnetite is extremely significant.

Previously, he also considered whether to abandon domestic sources and buy ore from the international market, such as Australia. Australia's ore grade is much higher than that of China, their highest grade ore has reached more than 70%, and there is no need for primary sintering, and the ore can be directly ground into the blast furnace to smelt molten steel, and its cost is far more cost-effective than using domestic ore, especially the iron ore in Panzhihua.

But thinking about it, thinking about it, thinking that Australia's iron ore is basically monopolized in the hands of two British-funded companies, Rio Tinto and BHP Billiton, it is too difficult to extract teeth from their mouths. Moreover, even if they spend money to pick up the leaks and get the mine, the supporting facilities such as railways and ports transported from the mining area are also in their hands, so they have to build railways and ports by themselves.

This investment is huge.

Spend so much money, in the future, if there is a dispute with the United States, sanctions by the West, and don't want to ship a piece of iron ore back from Australia, then why bother to spend so much money to help others build railways and ports, isn't this making wedding dresses for others?

From a safety point of view, it is best to use the most reliable domestic mineral sources!

After all, the base eats a technical meal, relying on the technical advantage, even if a slightly more expensive raw material is used, because of the advantage of labor productivity, it can also level the cost gap with competitors. Counting the advantages of cutting-edge technology, it is sold a little more expensive, and there is no fear that no one will buy it.

In that case, why should you put your life in the hands of others?
