The venue was quiet for a moment, and then, popping, a burst of applause rang out, and finally pulled Zhu Beiguo, who was outside the iQue window at this time, back.

However, after the applause, it was still quiet, everyone was thoughtful, and at this time, Zhu Beiguo finally woke up from the environment of the venue that had become quiet again, and he quickly stopped his steps very interestingly, and stood in place and hugged his fists to everyone:

"Oops! Sorry ha, sorry! Guys, I'm sorry, I'm sorry! I'm getting carried away, let's go a little far! ”

Bang bang bang bang bang

"Haha! Brother Zhu's speech is quite fascinating, much more interesting than our introduction to industrial equipment, you see that there is no yawning in the venue. ”

"Yes, it's still Brother Zhu's content that is fascinating."

"We're too boring, if those plots are written as novels, readers will have to scold the streets......"

Holley Quan Zhenhai An Hengtong and a few of them laughed, and they all waved their hands to Brother Zhu to say that it didn't matter, and after the brothers finished speaking, it also caused a burst of chuckles from everyone in the venue.

These are all big truths, in fact, if it weren't for the fact that everyone was going to travel to that era, Zhu Beiguo's remarks would be of little interest to ordinary people, but obviously the group of people here is not, no matter what angle the people in this room are, they have shown great interest in Zhu Beiguo's words, because the era that Dr. Zhu Da told is the era in which this group of people are about to be immersed and live in.

"Let's just say it, the metallurgical industry aid report is the right thing."

However, Zhu Beiguo stopped talking, hurriedly returned to his seat, and gave way to An Hengtong and them again. There were people in the room who sighed, mainly high school students, who were also interested in the various introductions of professionals, but they obviously did not understand much and lacked interest.

Zhu Beiguo noticed the emotional changes of the high school students in time, and he turned back to the group of young people and said:

"You are welcome to go to the dormitory to chat after the meeting, and let's discuss those topics of interest together......"

The high school students laughed when they heard this.

"So, I'll start all over again?"

An Hengtong looked at everyone in the venue and asked.

"Let's talk, let's listen carefully and promise not to yawn......"

Someone in the crowd responded.

"Well, what's that...... Right! Cholecopper method! The approximate process is what Cao Limei said just now, I won't say much about the details of the process too specifically, anyway, we have no problem with it, if it is combined with the fire method and the electrolysis method, the quality of our refined copper can be completely guaranteed.

However, the output depends on our ability to obtain raw materials, although there are placers on the seaside, but the beneficiation pressure is very high, which is more time-consuming and laborious.

Of course, in the early days, because we did not have external input raw materials, we could only barely use them, but we hope to be able to import various non-ferrous metals from the outside as soon as possible.

For example, the raw materials such as blister copper, tin sand, tungsten sand, lead-zinc coarse sand that existed in that era were produced in the South China Seas, and in that case, the large-scale production of metal fixed ammunition that you had been thinking about for a long time could become a reality! ”

"Well, it looks like we have to go out and find a source as soon as possible......"

"These mineral sands are available in the South Seas!"

"I heard that in that era, these raw materials were exported in bulk in the south of the Ming Dynasty."

"Yes, quite a few ...... through Macau"

"Guangzhou is also an export port!"

"Hey, do you remember how many of us went to Guangzhou to decorate people's water and electricity?"

"It's like a world away......"

Everyone: "......"

"Oops, sorry, sorry, you continue, we won't have a small meeting, resolutely not open!"

Wei Dongli and his brothers suddenly reacted and hurriedly made a statement.

"Well, according to the list that Anna gave us, this includes a set of sulfuric acid hydro-copper metallurgical equipment, in addition to the heap leaching tank that we need to dig ourselves, including the standard liquid collection tank, small low-temperature pressure cooker, electrolyzer and supporting electrode materials.

However, in the future, like the chemical industry, we will also face a major problem: electrode materials. This is a consumable product, and we need colleagues from other departments to work together.

In addition, in addition to the iron sulfate reduction method mentioned by Xiao Cao just now, Anna also gave us a can of high-concentration thiobacillus ferrous oxide liquid, which can reproduce on its own...... Well, rest assured, this is not used to fight biochemical warfare, it is a metal refining strain, which means that we can also use the bacteriological method to refine non-ferrous metals, which is specially used for the non-ferrous metal refining of low-grade copper-lead-zinc ore and associated miscellaneous ores and tailings!

This method can also refine precious metals, the formal scientific name is "biological leaching process", this process is very suitable for our current industrial base and resource conditions! ”

"So advanced, huh?"

"Also environmentally friendly ......"

"Crossing the weapon, this is ......"

"Does this count as a goldfinger......?"

"Alright, everyone! I'm done introducing the non-ferrous metallurgy piece."

An Hengtong did not respond to everyone's exclamation, decisively ended his speech, and sat back in his seat.

"That's it? So, it's your turn to speak, right? Wang Gong? Boss Luo? Xiao Wang Xiaohuang? Cheng Dong? Which of you will speak first? ”

In order to save time, Sun Lao directly named him.

"Huh? Oh! Boss Luo, let's talk about it first, I'll check and fill in the gaps with a few others. ”

At this time, Wang Xue was whispering to the female companions around her, and when she heard Sun Lao tell her to quickly raise her head and say to Luo Zhengyi.

"Then let me talk about it first, hello teachers and students, the current mechanical group is composed of six people in related occupations, Wang Gong, Cheng Dong, Huang Hai, Wang Nabin, Zhou Yuye and me, Wang Gong is a shipbuilding professional, Cheng Dong is a railway locomotive major, I am a mechanical processing major, Huang Hai is a mining machinery maintenance, Wang Zhou is a textile shoes and hat machinery.

Because the professions of the six of us cover almost all aspects of the mechanical industry, Anna has provided us with a variety of equipment for our professional range, which covers all aspects of machining, although the equipment is generally quite simplified or even rudimentary.

First of all, Anna gave us a complete range of metalworking equipment, turning, milling, planing, grinding, boring, drilling, punching, etc., all kinds of standard machinery factory tooling, measuring tools and cutting tools are also equipped very neatly, it can be said that the sparrow is small and has five organs.

Overall, the technical level of metal processing technology is probably the standard of the fifties and sixties of the last century.

But I have to remind you here that this does not mean that we must have the machining capacity of the 50s and 60s of the 20th century, because these equipment can only play a role as a copy reference, and we cannot use these equipment for continuous large-scale industrial production. ”

"Boss Luo, we know that these are used to copy the second generation, and then the third generation."

"Yes, of course, because of the industrial constraints of that era, we will make a more simplified copy.

Undoubtedly, this will make us pay a certain price, such as due to the decline in processing accuracy, resulting in the quality and variety of our industrial products, there will be different degrees of degradation, of course, compared with this era, if it is placed three hundred years ago, it must still be a rebellious existence.

I think this is an acceptable result, in addition, please rest assured, with the continuous progress of our machining technology and equipment, in the near future, our machining level will reach a certain height. ”

"How high can you go?"

Someone in the crowd asked.

"What, Boss Luo, can it reach the level of the fifties of the last century?"

Someone asked a more specific question.

"It's hard! Because we may not be in a position to bring the whole level of industrial development to the level of that period. But please listen patiently to Boss Luo's explanation. ”

Wang Gong interjected in time next to him, which reduced the discussion in the crowd a lot.
