"Mr. Ren, I won't dare to come next time." Yan Yuyan looked at the banner with a good reputation and shook hands with Ren Ping, chairman of the mining group, while saying helplessly.

"Show our enthusiasm." Ren Ping smiled and gently shook hands with Yan Yuyan and let go.

"This is Chen Lin, the general manager of our company."

"Hello, Mr. Chen, welcome."

"I've been disturbed."

"The sun is big, let's go in and talk."

“…”

"Mr. Yan, I heard from Mr. Chen that you Tianyan Technology needs tantalum?" After sitting in the conference room, Ren Ping first opened the topic.

"Yes, I don't hide it from Mr. Ren. After our calculations, we need about 1,500 tons of tantalum every year." Yan Yuyan nodded directly.

"Mr. Yan, about your tantalum, this amount is too large. You should also know that tantalum is a rare element and it is very difficult to extract it. Moreover, this is not the most important one."

"Because tantalum is a rare element and is attached to it. If we produce 1,500 tons of tantalum every year, it will be inconvenient for us to deal with other minerals produced and refined." Ren Ping asked in confusion: "Can your Tianyan Technology extract tantalum from nature, can't you extract tantalum from nature?"

"Then we need to extract tantalum for us." Yan Yuyan said: "If it can, we won't bother you Mr. Ren."

"Now our annual output of tantalum is about 450 tons. If you add the output you want, it will be 2,000 tons." Ren Ping thought for a while and said, "We can increase the output, but the price will be a bit expensive. I hope Mr. Yan, you must be prepared for this."

"How many?"

"It's about 2.6 million tons."

"Yes, we can accept this price." Yan Yuyan had learned about the relevant price before coming. The price was 2.6 million/ton, and the price was quite fair.

“Even if the supply is as fast as possible, it will take three months.”

"Can't you get a little earlier?" Yan Yuyan said: "Mr. Ren, you should also know that the tantalum element plays a very important role in deepening cooperation between our Dahan and D country."

"This is the fastest." Ren Ping smiled bitterly: "We purchase equipment, expand mining areas, etc. for three months, which can be said to be the limit of time."

"I mean in three months, you can provide you with more than 100 tons per month."

"Before this, it is natural that there is no problem to provide a small number of samples."

"Okay, then please Mr. Ren, please give up on this matter." Yan Yuyan had to give up when she saw Ren Ping say this.

"Don't worry, your affairs will never be delayed." Ren Ping patted his chest and promised.

No guarantee, no.

Now the upper part is fighting with the Lifeng Empire.

And Tianyan Technology can be said to be at the forefront.

As a state-owned enterprise, if you don’t have the ability to see it, you don’t have to mess around and go home to grow sweet potatoes.

"The detailed process after that will be communicated with you." Yan Yuyan didn't have time to pay attention to these small details, and she was busy with a lot of things.

If it weren't for the tantalum being too important.

Yan Yuyan threw it to Chen Lin directly and took responsibility.

"No problem, I will communicate with Mr. Chen in the future."

“…”

Yan Yuyan threw the roughly agreed on the cooperation and gave it to Chen Lin for handling.

At this time, Liu Tian received a call from Ren Dafei.

"Liu Tian, ​​are you free?"

"Can I say I'm not available?" Liu Tian quipped: "Why, Mr. Ren, what are you going to care about?"

"Okay, don't be poor with me, kid." Ren Dafei said directly: "Is there something I want you to help?"

"You said?" Liu Tian put away his joking heart.

"Do you remember the machine tool company?"

"What's wrong?" Liu Tian asked in confusion.

"Now the machine tool company has built a new machine tool, but the accuracy is not good." Ren Dafei explained: "Lu Dingwen, the chief engineer of the machine tool company, said that this is a material problem, so..."

"What kind of material do you want?"

"If you come here conveniently, I don't understand this thing, and I can't say anything."

"Okay, please send me a location." Liu Tian thought for a while and finally decided to go and check it out.

"good."

“…”

Ten minutes later, Liu Tian sent a message to Yan Yuyan and followed the navigation directly to the location (Lianjing Machine Tool) in the western suburbs of the capital.

One hour later.

Liu Tian came to Lianjing Machine Tool.

Under the leadership of Ren Dafei, Liu Tian came to a super-large workshop of more than 10,000 square meters, and watched a lot of people spinning a big guy about 6 by 4 by 2 meters.

Oh, there are quite a lot of acquaintances.

Lei Mingjun, Jiang Yun, Chen Xiaolong, Zhang Wen... these big guys are all there.

"Are you a medium-sized machine tool?" After saying hello, Liu Tian asked to a thin old man (Lu Dingwen) who was about 60 years old, half a head of white hair and about 1.65 in height, "What is this working range?"

"Yes, this is a medium-bed machine tool, and the maximum working range is 4 meters by 2.5 meters."

"What's the problem?" Liu Tian asked after walking around the machine tool.

Lu Dingwen directly said: "We have designated this machine tool as lj0001, with a positioning accuracy of 0.5um and a reset accuracy of 5nm. Now the reset accuracy has reached the design accuracy, but the positioning accuracy is 100 points worse."

"After our repeated exclusions, the problem can basically be determined to be on the moving shaft arm."

"Now the material of our shaft arm is Seiko No. 889, but this material can be said to be the best we can buy in China."

"If you want to improve the accuracy, you can only find better materials."

"Otherwise, this problem cannot be solved."

"Are there any detailed data on this No. 889 material?" Liu Tianwen asked.

"Some." At this time, Zhang Tie (general manager of Lianjing Machine Tool) quickly found a piece of information from the table not far away and handed it to Liu Tian.

"I'll take a look first." Liu Tiannian browsed roughly. The strength was 800c, the compressive resistance was 1100mp, and the extension was 1300pa... After reading the information, he asked, "What kind of materials do you want?"

"???" Everyone's eyes moved to Lu Dingwen.

"The strength should be above 900, compressive resistance should be above 1250, and extension should be above 1400..."

"This performance is probably a bit difficult." Liu Tian is not a rookie who doesn't know anything. If you want to meet Lu Dingwen's requirements, let alone domestically, you may have to be available in foreign laboratories.

"Can you do it? Can you ask the above?"

"The above is probably enough." Liu Tian shook his head directly. If it meets the performance standards, it should be easy to find, which means three main performances meet the requirements, which is not necessarily true: "I will ask back and ask, can I take this information away?"

"OK."

"Okay, I'll study it back. Is there any? I will reply as soon as possible." Liu Tianwen said: "Is this a question of material?"

"Yes."

"Can the accuracy be launched now?" Liu Tian thought of a key question.

“Let’s go public?”
