Lan remembered it very clearly. Shortly after the announcement of the news by CITIC Heavy Industries Group, it was 428 in 006. In addition to that 10-ton hydraulic press at the Shanghai Heavy Machinery Factory. China's second press of more than 10,000 tons: Erzhong Group announced that the important parts of its group's 1-ton hydraulic press were successfully poured at one time.

At that time, the newspapers reported these two news very intensively for a while. And compare the press of Erzhong Group and CITIC Heavy Industries Group over and over again. Anyway, there are only two points of view: one is that the 100-ton free forging hydraulic press of the Erzhong Group is more in line with China's current national conditions. CITIC Heavy Industries Group's 18,500-ton free-forging hydraulic press is inevitably suspected of grandstanding; The second view is diametrically opposed. Think in this day and age. CITIC Heavy Industries Group dares to aim for the world's largest and most advanced ultra-heavy-duty free-forging press, which is not even available in the United States, Japan and Europe. As long as it can be built successfully. Not only for the development of domestic related industries. Even the improvement of the overall level of the manufacturing industry in China. All have an immeasurable role.

The media is super lively. Zhang Lan can't care either. But Zhang Lan knows a thing. This 1,800-ton free-forging hydraulic press from CITIC Heavy Industries Group. Back in the design days. Strict requirements are put forward for forging accuracy: the size is fine, and the error is required to be plus or minus no more than 2 mm. The rotation accuracy error of the manipulator is within plus or minus 05 mm!

To know. This press is going to do the job. That's hundreds of tons of big guys! Such a small error. Let the world's largest press take forging to the next level. It is already equivalent to precision forging. Although the world's largest and most advanced free-forging hydraulic press had not yet been built before he was reborn. But faith should succeed, right?

At the beginning of the CITIC Heavy Industries Group, this 18,500-ton hydraulic press was forged. It was in cooperation with the Germans. The mechanical part of the press was all handled by CITIC Heavy Industries itself. The electronic control operating system part is a 750-ton-meter manipulator provided by the German company DDS. The hydraulic system is the "Panke" hydraulic system technology provided by the German Wipke.

Zhang Lan secretly wondered in her heart: With the help of Xiao Chenxi, Alice, Brother Zhuzi and Brother Tian, could she make things out by herself. Can't it be better than this thing made by the Germans? The electronic control system and hydraulic system are also the technical strengths of Xiao Chenxi, Alice, Brother Zhu and Brother Tian. If the efforts of the four of them could not beat the Germans, if they gathered Xiao Chenxi, Alice Zhuzi and Tiange. I don't think I need to say it myself. These four people are ready to let Brother Tian experience the gravitational acceleration of 98/s from a height of 300 feet.

"18,500 tons?" Xiao Chenxi lowered her head and pondered for a moment. "I looked it up just now, it seems like you're in this world. I don't have such a big press yet. If so. If we really set up a comprehensive heavy industry group. With such a big dick. Together with the various equipment and engineering supporting it, our heavy industry group will be able to supply 900 tons of refined molten steel at a time. The maximum casting production capacity is 600 tons; The maximum ingot production capacity reaches 00 tons, and the maximum forging production capacity can reach 0 tons. It has the processing capacity for large castings and forgings such as nuclear power, thermal power, hydropower, etc. It even has the ability to mass-produce the world's largest mills with diameters ranging from 12 meters to 14 meters. ”

Said here. Xiao Chenxi nodded. "Hmm. The choice of tonnage is good, if it can be built successfully. Not only to be able to satisfy the country. Even a lot of international forging orders have come to us. Such large, precision-machined components. Each piece is processed. It's not cheap. ”

"If such a heavy industry group is really established. There is such a forging ability. Alice said. It seems that nuclear power forgings, medium and low pressure rotors, hydrogenation vessels, aerospace forgings, large supports, large marine castings, forgings, large steam turbine cylinder blocks, large water turbine runners, large rolling mill stands, large graphite iron castings, ductile iron parts. We can produce these things, such as molded and colored castings. "I thought about it. And added a little more uh-huh. Plus the supporting facilities with this 1800-ton free forging hydraulic press. Not only enough for the production of hull parts for large submarines. Even the large forgings needed for the largest Nimitz aircraft carrier in the United States can be produced. ”

My day! Hear Alice say that. Zhang Lan was dizzy for a while: Master, I only know that this guy is very powerful. But I didn't expect this guy to be so powerful that the forgings needed by the Nimitz-class aircraft carrier can be produced? I'm crazy!

"Many companies now have their own large presses. Companies and groups that need their own capabilities have already been on the existing enough for them to use. There will be no further updates anytime soon. Those who don't have the ability can also be customized directly from me.

moreover

The market for castings and forgings is also limited. According to the heavy industry group of international and domestic customers once entered. Forcefully saturate the market. Xiao Chen thought for a moment. He nodded in affirmation. "If our plan can succeed. Then predictable. In the next 30-50 years. There is no other company in the world with such a large press of this size and capacity. ”

"Designing something so oversized. Brother Tian, Brother Zhuzi, they have experience. Xiao Chenxi said. We at Cybers Planet are superior in terms of electronic systems and controls. Brother Zhu: They are excellent in large-scale high-precision machining. ”

That's right. Think about Brother Zhu and Brother Tian's oversized bodies - look at Xiao Chenxi and Ellie's relatively slender figures. Zhang Lan nodded: Although the technology on both planets is very advanced. But the technological development of two planets next to each other. It can be regarded as two different levels of high-tech development. Although Xiao Chenxi, the heavy equipment on their Cybertron planet is definitely a lot compared to Brother Pillar's on their Cybertron planet.

"Okay." Zhang Lan thought for a moment. "Let's go and ask Brother Zhuzi's opinion. Let's see what good advice Brother Zhu can give us. ”

"That's it." Sitting in the super big Hummer that the pillar brother becomes. Parked next to it is the iron version of the Super Hummer. After telling Brother Pillar Iron Sheet about his plan. Asked. "What do you think?"

"No problem." Brother Zhu said. "It's very simple. Mere trifle. In our place it can only be considered a pediatric thing. I have the information here. Well. Now I'll pass it on to Princess Dawn. Belch. But ......"

As long as Brother Zhu says the word "but". Zhang Lan knew. There must be a problem. He asked with a worried face. "But what?"

"But with the technology and control of your ball." Brother Zhu said. "It is estimated that the accuracy of this hydraulic press will be much worse." ,

"Ugh. I asked. Hearing Brother Zhuzi's words. Zhang Lan cautiously asked the two little girls. "If you let you design this press. According to the current level of technology available on the ball. How accurate can you achieve in your design? ”

"Precision?" I heard Zhang Lan ask this question. Xiao Chenxi quickly compared the information she received from Brother Zhu Zi with China's current technical level. After the calculation. "Hmm. It is indeed much worse than the manufacturing accuracy on our planets Cybers and Cybertron. According to your current technical level in China, if the mechanical parts can meet our design requirements. Then the dimensional accuracy error of this press we designed should not exceed plus 02 mm. The rotation accuracy error of the manipulator is within plus or minus 00 mm. So-so should be considered okay. No way. It can be improvised. "Speaking of which. Xiao Chenxi looked regretful. "Alas. It's a pity that your skills on the ball are too backward. This is a reasonable requirement that we can achieve between performance and cost. Well. That is, the best price-performance ratio. If you improve the accuracy even more. Some of them are not worth the cost. Not necessarily. ”

Xiao Chenxi's words. Zhang Lan almost didn't fall headlong when he heard it: the 1,800-ton free forging hydraulic press of CITIC Heavy Industries had an error of plus or minus 2 mm for dimensional accuracy. The rotation accuracy of the manipulator is wrong; plus or minus 05 mm. The world's largest machine, the level of forging of machines. It is already equivalent to precision forging.

Xiao Chenxi and Alice made something out of these two girls. The machining accuracy is compared with the 18,500-ton press of CITIC Heavy Industries Group. But you can increase the accuracy by a full ten times! This is no longer equivalent to the problem of precision forging. It is a real high-precision forging! Even the Americans, and the Germans, who were the most advanced in this field, could not reach this accuracy!

Zhang Lan thought about her own good things: as long as her 185-ton free forging hydraulic press was successfully manufactured. Then this pressure of his own has become the largest, most advanced and highest precision hydraulic press in the world! When the time comes, the Yankees want to engage in some large forgings that require high precision. Also from their own hands!

There is one thing that is really worth celebrating: although many people today. But for Zhang Lan who was wandering around. No one came to disturb them. Otherwise, just come over alone. It was found that Zhang Lan, Xiao Chenxi and Alice were talking to the two cars. And these two cars were able to respond. I guess I can faint directly!

These guys are funny! There are really people who dare to come and mess with their own affairs. It doesn't matter who this guy is. Be sure to beat this guy's nose and face to be swollen!

"So that's it?" Zhang Lan asked. In fact, it is equivalent to asking in vain. As long as he decides on things. How could Xiao Chenxi and Alice disagree?
