Chapter 711: Another special steel

Hongriling Iron Mine.
Several of Qin Tian's assistants were busy, setting up measuring instruments to survey and map the situation of this iron ore, while Qin Tian carried his hands on his back and stood in front of this large open-pit mine. In his mind, a plan gradually emerged.
From yesterday to today, in this iron ore mine for so long, plus some major data has been mapped out, Qin Tian already basically knows how to plan this large open-pit iron mine with an annual output of 200 million tons of finished products , How to build.
"Xiao Yang, bring paper and pen!"
As a planning expert, Qin Tian's freehand drawing skills are very good. Holding a pencil, on a piece of unfolded white paper, think about it for a while, and then rustle up, basically without stopping. He seems to be confident and wants to do it in one go.
After half an hour.
The planning sketch of the Hongriling Iron Mine is already on paper. Next to him, several of Qin Tian's assistants look admired, they are worthy of being experts, and the planning sketch is completed in this way.
Qin Tian put away his pencil, looked at the plan sketch, and said, "Basically proceed according to this plan. You can complete the details."
As an expert, he does not need to do the specific planning and design by himself. With his great helper, everyone will use the data from surveying and mapping and the framework built by Qin Tian, ​​such as perfecting on the basis of this planning sketch. , The design is more specific, and finally Qin Tian can check it.
Qingyang Hotel.
Wang Xudong got up late. After washing, he did not rush to have breakfast. Instead, he turned on the "God-level Mine Owner" system to see how many ordinary energy points it had absorbed!
my God!
There are 41282!
Behind the No. 2 energy slot, the number representing the ordinary energy point is "41282/60000". Even Wang Xudong has never thought about it, and has absorbed so many energy points.
This is only with Qingyang City as the center and within a radius of 500 kilometers. If you go to Leidong City and get closer to Cao County to cover Cao County, it is estimated that more energy points will be absorbed.
More than 40,000 energy points were far beyond Wang Xudong's expectations. He thought that it would be good to absorb thousands or tens of thousands of energy points. I didn't think there would be so many.
Humming a small tune, Wang Xudong walked out of his room, eating breakfast first.
When Chen Sanlian and his son were not there, Wang Xudong knew that he must have gone to Qingyang City Government or Qingyang Special Steel Group to discuss the transfer of Qingyang Special Steel Group with Qingyang City.
Wang Xudong has fully authorized and fully believed in Chen Sanlian. He didn't want to bother with this acquisition at all. He was happy and leisurely. After eating breakfast beautifully, he took Lin Hu and went out.
Yesterday, did Chen Sanlian say that bearing steel, especially high-grade bearing steel is very popular, and hope that Sanlian Special Steel Group can smelt the world's top bearing steel. Wang Xudong is going to get a high-grade bearing, and then come back for a good analysis. Some.
The "God-level big mine owner" has the "analysis" function against the sky. As long as there is a sample of the special steel, it can analyze the full set of smelting technical data of this special steel, and it is better than blue.
Wang Xudong is not a layman, and he also knows the importance of bearing steel. For a large industrial country, bearings are very important, and to manufacture high-end high-quality bearings, you must first have high-quality bearing steel, and China lacks high-quality bearing steel.
Bearings have a high technical content and can be used as an important standard to measure a country's technological and industrial strength.
Today's world's technological and industrial powers are without exception the bearing R&D and manufacturing powers. The reason why China is an industrial power rather than an industrial power is that the bearing industry is large but not strong.
According to incomplete statistics, last year, Huaxia's bearing industry sales reached more than 150 billion Huaxia Coins. The main products produced were middle and low-end bearings, while high-end bearings were mainly imported.
Wang Xudong also heard aviation expert Lin Yunwen mentioned before that whenever he mentions high-end aviation bearings, Lin Yunwen sighs in addition to sighs.
He even said that if Huaxia itself can manufacture the world's top aerospace bearings, the manufacturing level of the entire Huaxia aeroengine will be raised by half.
It is precisely because of the lack of top-level bearing steel that the high-reliability and high-precision top-level bearings used for aero-engine matching have become the "Mount Everest" that China is difficult to overcome in the research and development of aero-engines.
Since Chen Sanlian also mentioned bearing steel and expressed his desire to smelt this special steel, Wang Xudong is ready to give it a try.
Where to find the world's top bearings, Wang Xudong has a way. Naturally, he goes to Lin Yunwen. He is an aviation expert. There must be many world-class bearings in his place.
Of course, before you go, you must contact Lin Yunwen and go there.
Wang Xudong took out the phone and contacted Lin Yunwen. He was lucky. Lin Yunwen was in his research institute and heard that Wang Xudong was coming. He was very pleased. He said on the phone that he would come to the airport to pick him up.
Now Lin Yunwen is full of spirits. A new type of military aero engine led by him has been successful. A verification prototype has been manufactured. A series of verification tests are underway. From the test run, everything is very good.
The mass production of this engine is just around the corner, and Lin Yunwen is excited when he thinks about that his engine can be fitted with the war eagle of the motherland.
To achieve such a great success, Lin Yunwen clearly knows that it is not his design level that is superb. It is mainly Wang Xudong who has solved his two major technical problems. If there is no super stainless steel and super high temperature alloy steel developed by Sanlian Special Steel, he Lin Yunwen does not have such great ability to make this engine development progress so smoothly.
I heard that Wang Xudong was going to take a look, Lin Yunwen didn't ask any questions, and immediately raised his hands in agreement, and strongly welcomed Wang Xu's arrival.
Wang Xudong had a special plane, took Lin Hu, and took his "car" to fly directly to the city where Lin Yunwen was located. Before noon, Wang Xudong arrived at his destination.
When he stepped off the plane, Wang Xudong felt in his heart that he still had the convenience of a plane. With such a long distance, he would come whenever he wanted, and he would arrive so soon.
"President Wang!"
Lin Yunwen had already waited at the airport early, and when he saw Wang Xudong stepping off the plane, he immediately shouted with joy, almost running all the way.
Wang Xudong said: "Expert Lin, it looks like he is getting younger and younger."
The development of his own engine is progressing smoothly, and there are basically no more thorny problems. Lin Yunwen's brow wrinkles are less, he is in a better mood, and looks really younger and younger.
Lin Yunwen said: "I have to thank Mr. Wang. If it weren't for the materials provided by Mr. Wang, I wouldn't be as easy as I am now. Let's get in the car first."
Not far away, Lin Yunwen's car was parked. The two got into the car while talking. After leaving the airport, Lin Yunwen said, "Ms. Wang, shall we go to eat first, or..."
If you eat now, it will be a little early, this is to seek the opinions of Wang Xudong. Wang Xudong said: "I heard that the aero engine developed by expert Lin is very advanced. I wonder if you can take me to take a look."
Even if this newly developed aero engine has a confidentiality requirement, it is Wang Xudong. He asked to take a look at it. Naturally, there is no problem.
Lin Yunwen didn't even think about it, and said readily, "No problem, then we will go now."
After the car left the airport, it went directly to an aero engine manufacturing plant. This is a large state-owned factory, which is famous in the domestic aero engine field. It is responsible for manufacturing the designed aero engine.
In China, the aviation engine field basically adopts the research institute + factory model, which is first designed and developed by the research institute, and then manufactured by the manufacturing plant according to the design drawings.
Under the leadership of Lin Yunwen, he went to the assembly workshop of this factory. In the huge assembly workshop, Wang Xudong saw more than one type of engine, including the one designed by Lin Yunwen.
One of this engine is undergoing a 300-hour test run and is undergoing disassembly and inspection. Lin Yunwen led Wang Xudong to the front of this engine and said, "Mr. Wang, this is our newly developed aero engine with world-class level..."
At the time of the introduction, Lin Yunwen's face was full of pride. He was full of accomplishment to successfully develop this engine, and he was not proud of it.
Wang Xudong listened patiently to Lin Yunwen's introduction, but his eyes were fixed on the several main bearings that had been removed, and he pointed to one of them and said, "Expert Lin, are these imported bearings?"
Lin Yunwen sighed slightly: "This is not imported. Foreign countries have severely blocked our technology. High-end imported aviation bearings are very expensive and difficult to buy. These are only domestically produced."
If it is imported, Wang Xudong will definitely be very interested, and will start the "God-level big mine owner" system to quietly "analyze" it. If it is made in China, there is a little hesitation.
Even a layman, Wang Xudong knows that domestic bearings are inferior in quality to imported ones, especially for aviation bearings. There is a big gap between domestic ones and imported ones. This gap is not manifested in the manufacturing process, but in the materials. on.
The difference in materials determines that domestic aerospace bearings are much worse than imported ones. At present, for Lin Yunwen’s aero engine, the main bearing can only use domestic bearings for the time being. Imported main bearings are currently being purchased. in.
The engine is being disassembled step by step ~EbookFREE.me~, and the speed is relatively fast, and soon it was disassembled into several major parts by a few skilled workers, and then further disassembled into individual parts. After becoming a part, it must be cleaned and then carefully inspected. Including these main bearings.
The main bearings were removed and sent to be cleaned immediately. Then they were sent back. Several technicians and inspectors first inspected the main bearings.
One of the technicians in charge, wearing white gloves, holding one of the main bearings, looked very carefully, but soon his brows wrinkled.
"Mr. Lin, there is a problem with the bearing!"
Lin Yunwen walked over a few steps immediately, picked up the bearing and looked at it, then picked up the magnifying glass, facing the light, looking seriously, his eyebrows gradually wrinkled into a horoscope.
Wang Xudong asked with concern: "Expert Lin, what's wrong?"
Lin Yunwen slowly said, "The thing I was worried about finally appeared!"
