This is a drawing of a magnetic separator for magnetic materials.
The principle of the magnetic material separator is exactly the opposite of that of the iron ore magnetic separator.
The iron ore magnetic separator uses magnetic adsorption to select iron ore powder.The refined iron powder absorbed by the magnetic separation of the magnetic separator is retained, and the impurities are removed.
The rare earth permanent magnet material itself is magnetic.The coil can be used to generate a magnetic field to adsorb mineral powder of permanent magnet material.
However, magnetic separators that use steel and other materials to make permanent magnets can retain the permanent magnet materials, but they cannot be cleaned up. The collection process is very complicated.
Therefore, the material selection, magnetic field isolation, power supply, magnetic separation material collection, etc. of this permanent magnetite powder selection system are all systemic problems with high technical content.
That's why Zheng Cheng took it out to discuss it with everyone.
"Use stainless steel as the main frame of the magnetic separator!"
"It is more suitable to use aluminum alloy!"
"Aluminum alloy is not good! Not wearable!"
In the conference room, the technicians made speeches one after another, putting forward their own ideas and methods.
And their ideas are all imagined out of thin air, without experimental data to support.If this discussion continues, it will be difficult to discuss any results in an afternoon.
Xu Zhenming is also a layman with regard to such technologies.But he wants results, not open discussions.
Seeing that everyone's opinions were not uniform, he had to knock on the conference table: "Dear colleagues! Judging from the question raised by Minister Zheng, this problem exists in our production lines, such as injection molding machines, crushers, grinders... etc. At today’s meeting, we will first determine the main materials, and then discuss the details."
"From the perspective of material strength and workability, I think it is more reasonable to choose aluminum alloy. Then, in order to prevent wear, how about we choose stainless steel for wear-resistant liners?"
He put forward his own ideas, but also synthesized the opinions of some people.
"Mr. Xu, you said that there may be a problem with this scheme! Aluminum alloy has high hardness, but not strength!"
"Yes, although aluminum alloy is easy to process, how can it be made into equipment? What should I do if there is no finished aluminum alloy plate, bar and other materials?"
All of you present here are technical technicians, and it is not because Xu Zhenming is the boss that he would not raise any objections.
The questions they raised also have some truth.
Seeing this situation, Xu Zhenming needed to make a direct decision to determine the main materials of the main equipment of the permanent magnet production line.He looked at the crowd and said, "Since stainless steel is easily magnetized, it can only be used as a wear-resistant liner for equipment. Doesn't you have any comments on this?"
Everyone nodded.
"Aluminum alloy materials are not easy to manufacture finished products, so we use pure aluminum materials to make them. We cancel the welding process and use the riveting process to make the equipment. Do you have any comments on this?"
Since the consideration is so detailed, everyone has no opinion.
It's just... pure aluminum, are there plates and bars on the market?
In this regard, everyone is still quite skeptical!
"The purchase of raw materials is a matter for the purchasing department. You only need to design the mechanical drawings according to the actual situation! It is really not possible. We will sell the aluminum ingots back and process them into the blanks ourselves!"
Xu Zhenming waved his hand to make everyone stop considering these details.
Later, he asked Zheng Cheng to investigate the drawings designed by the permanent magnet factory and display them on the projection screen.When the concept map was displayed on the wall, the members of the group who were not involved in the project were stunned.
I see.
In the future permanent magnet workshop, there will be pipes everywhere, and each equipment system is equipped with a dust collection device. After purification by the dust collector, the factory exhaust can be discharged.The cost of this system is probably no less than the main equipment of the permanent magnet, and the cost of production and operation is also very high.
"Our crushing workshop does not have this kind of dust device! Why do we need to increase this process?"
"The grinding workshop is the same!"
"Yes! The same goes for the magnetic separation workshop!"
The technicians who had merged from Nan'an Magnetic Material Factory all looked at Zheng Cheng with surprise at this time, and then at Xu Zhenming.
Zheng Cheng was smiling wryly.
He made the factory design based on Xu Zhenming's opinion.According to his original intention, the dust was directly extracted and discharged with a large chimney.
But Xu Zhenming disagreed: “There are rare earth materials in the collected dust, which can be reused after rough selection. The dust after rough selection can also be sold to dealers engaged in rare earth materials.”
In short, he must add this set of dust collection and purification equipment, and discharge the exhaust gas of the factory after it is qualified.
"Colleagues! With this device, the working environment of the operators is much better, and they will not get the occupational disease of "pneumoconiosis"! Now I invite you to consult, mainly, is there any room for improvement?"
Zheng Cheng explained.
"Oh…"
Everyone suddenly realized that they almost forgot the business of reviewing the design drawings.
"Mr. Xu and Minister Zheng! In this case, I suggest adding a ceiling isolation to the workshop. Operators operate equipment switches, valves and actuators on the first isolated floor, while the second floor is for exhaust gas collection. Is this more reasonable? "
Seeing this, someone put forward this opinion again.
"This method is good, you can consider adding it!"
"With this design, can the fire department pass?"
Others immediately put forward two points of view, but they all think this approach is better.
Xu Zhenming also thought it was good, nodded and said, "You don't need to consider the fire protection problem. As long as the factory layout is reasonable!"
Since then, the design of the permanent magnet production line, the large frame has been determined.
"Now that the plan has been determined, when can your project team produce this set of drawings?" Xu Zhenming asked with a serious expression after looking at everyone present.
He needs a relatively accurate time to arrange the funding plan for Yiming's project research and development.
After hearing this question, Zheng Cheng didn't dare to jump to conclusions.
He discussed with each member of the project team, and then reported to Xu Zhenming: "Report to Mr. Xu! Because this set of drawings has a master drawing for reference, we think that the official drawings will be available by the end of September. Testing machine In terms of production, I’m afraid it’s more than one and a half months!"
"Okay! Just follow your agreed plan to tackle the problem! But every week I have to report the progress of the project to me, and the company must arrange the funds reasonably!"
Xu Zhenming nodded and agreed with Zheng Cheng's plan, and then left the meeting room with his black notebook in between.
The project exchange meeting in the conference room will continue to discuss some technical problems.
Xu Zhenming had just returned to his office, and the phones on the desk and the phone rang.
"Mr. Xu! It will be the end of the month soon, are you coming to Jiujiang City?" Pressing the answer button of Big Brother, Wang Zhuoya's voice floated from inside.
At the same time, Duan Meisheng asked in the receiver of the phone: "Mr Xu! Do you have time? I want to report to work!"
After thinking for a moment, Xu Zongming said into the microphone: "Director Duan, you will come to my company in ten minutes!" Then, he hung up the call.
"Haha... Mr. Xu! Your work is so busy, do you want to borrow two phones at the same time?" Wang Zhuoya's laughter floated from the big brother.
Seeing this, Xu Zhenming frowned and said, "Sister! There are still a few days before school starts on September 1. Don't worry, I will come to Jiujiang City and drive you to the Law Department to report! And, what? Lu will come together too!"
He knew what Wang Zhuoya meant by calling, so he directly stated his plan.
At this time, Wang Zhuoya’s laughter floated from the big brother Dali, "Mr. Xu, I didn’t mean that! Hahaha...I laughed to death. That’s it. Song Yuan organized a signing ceremony for a servo motor to enter the park. I want you to participate. The time is... August 28!"
On the phone, Wang Zhuoya was deliberately playing a punctuation game.
"Oh? Has the 30 million yuan loan come down?"
Upon hearing this news, Xu Zhenming asked in surprise.
"30 million yuan? Too little, right? I told him that we want our company to start the servo motor project immediately. Without a loan of 50 million yuan, the project would not be able to operate at all. He told me that there was no problem, as long as Mr. Xu came in person. At the signing ceremony, everything is easy to talk about."
At this time, Wang Zhuoya didn't laugh any more, but reported the situation seriously.
The news was a bit too sudden, and Xu Zhenming was surprised: "Where did Jiujiang get so many loan quotas? Yiming is building six servo production lines at the same time. Can it be arranged?"
After much deliberation, he decided to go to Jiujiang City and have a face-to-face talk with Song Yuan.
So he said to his eldest brother: "At 7 o'clock in the morning on August 28, I will rush to the office downstairs. You arrange the work agenda!"
After hanging up the phone, Xu Zhenming was in a daze at the servo motor production report on the desk.
Twenty days later, the two servo motor production lines will be shipped. Shi Zhixiang and Yamamoto Jian will be stationed in Nan'an City within half a month to supervise the two first-generation servo motor production lines.
At the same time, Italians have often been stationed at Yiming Company to track the manufacturing progress of CNC machine tools and plate production lines at any time.
It can be said that Yiming has to produce at full capacity in order to meet the demand for these large orders.
"Fortunately, we merged with four bankrupt companies and Nan'an Electric Welding Machine Factory! First of all, our current human resources are no problem, and the production site is definitely no problem."
Thinking of this, he muttered to himself.
When thinking of the production site, he has an impulse to go to the front desk immediately to direct the layout of the large-scale riveting and welding parts manufacturing base, and want to put this 200,000 square-meter manufacturing base into use as soon as possible.
"Boom boom..."
At this moment, someone was knocking on the double-opening wooden door of the office.
"Come in!"
Xu Zhenming retracted his thoughts, took out a black notebook, and recorded the recent major events that he needed to deal with in person, preparing to make a simple plan.
At this time, Duan Meisheng walked in with two frequency conversion motors.
He reported with a grin: "Mr. Xu! This is our company's own inverter motor, and this is a product of Nissho Sanlin. Look at the workmanship, which one is better?"
While talking, he put the two inverter motors on Xu Zhenming's desk.
