During this period of time, Chen Lidong has been tinkering with the system whenever he has time, trying to research some things, inputting materials, spending gold coins, hoping to research something new.

What did he get at the beginning? Roller! Roller for rolling steel.

The tie-up roller is a component that often needs to be replaced on the steel rolling line. He heard Li Lixin say that because he bought a second-hand production line, the equipment often had problems, and it was troublesome to replace the rollers frequently.

Chen Lidong thought, well, I will study rolling rollers.

So I summoned the system and clicked on technology research and development. The system prompted: Please select the technology research and development category. This system focuses on industrial application research. You can choose materials, components, tools, equipment, processes, application software... Please enter the research and development category.

Project content.

Rollers are parts, right?

"Parts, Rolls"

"Please set the type of development roll"

"mmp"

"The information entered by the host is invalid, please re-enter"

"I'll go"

"The information entered by the host is invalid, please re-enter"

...

How could Chen Lidong know the type of rolling roller? He was stupefied when he came up with this fill-in-the-blank question. A liberal arts student is incompetent.

What should I do? I can only go to Li Lixin to ask for the answer. Fortunately, Li Lixin understands more or less and told him: there are cast steel rolls, cast iron rolls, and large steel rolling plants use forged steel rolls.

Chen Lidong then ordered the system to develop "cast steel rollers".

The system prompts, "Please enter the materials used to develop the 'cast steel roll' of this project."

Okay, I’ve made an entry. I don’t know what materials to use?

"Brother Xin, if you want to produce cast steel rollers, what materials will you use?"

"Of course we use cast steel, but we also use high-chromium steel and tool steel."

"High chromium steel just has chromium added, right? What is tool steel?"

"Chromium-containing steel has high hardness and is corrosion-resistant. Tool steels are generally carbon steel, alloy steel, and high-speed steel. They are mostly used on lathes. The main reason is that this kind of steel has high hardness and is wear-resistant. Sit down for a while, and I'll

Go to the workshop and have a look. There has been something wrong with the fan motor in the past two days. Let me see if it has been repaired."

Chen Lidong continued to input and developed cast steel rolls, using materials: cast steel, high-chromium steel, alloy steel, and high-speed steel.

System prompt: The research and development platform has not generated cast steel, high chromium steel, alloy steel, and high-speed steel materials. Please replace the materials used by the host, or develop the required cast steel, high-chromium steel, alloy steel, and high-speed steel first.

Chen Lidong was bawling for a while, filling in the blanks step by step, and now that's all, you tell me I don't have a condom?

Okay, no rush, let’s get the cast steel first.

Re-established project, research and development projects: metal materials, cast steel.

"Please select the chemical composition and proportion used to develop the 'cast steel' of this project. You can enter the main components and proportions, and other elements can be fuzzy."

Did you change your major to chemistry so quickly?

Chen Lidong exploded: I have only studied chemistry for two years in junior high school, but I have forgotten it more than 30 years ago! I can’t even name the first 20 elements in the periodic table, what do you want me to do?

Just do whatever you want, cast steel, there must be iron, carbon, add chromium, add manganese, these days recycling scrap steel, these elements have been produced a lot. Other blurring processing is correct, let the host fill in the blanks, and still

Study a p!

"Please set the experimental method used to develop the material 'cast steel'. Note that the host is asked to imagine the research and development process and scenarios of this experiment as fully as possible, and describe the production, processing, and forming processes to be used for this material; set the required

Parameter conditions such as temperature, humidity, pressure, etc.; the process flow and the time required for each process link;... The industrial assistant will conduct scene simulations in the system space according to the host settings, and ultimately achieve the development goals and requirements. The first experiment

, Keywords can be used to define the basic content of this experiment, and other things can be blurred. The subsequent experimental process can be adjusted, revised, or the method or path changed based on the initial experiment."

Finally, I changed the essay topic. Chen Lidong has been teaching and working in politics, and has been engaged in writing for decades. There is no problem in writing. He can describe the experimental process, how to do it? The only choice is to compile it!

To cast steel, you must first have molten iron, then it needs to be smelted. In the furnace, the molten iron is added with trace amounts of heavy metals such as manganese and chromium to form an alloy, and then cast into a mold, and finally cooled... and the shape is shaped into a roll.

The size and shape, that’s it, it’s over! Hey, this is more difficult than giving a report at a conference.

"Please enter the gold coins required for this research and development"

Haha, it’s finally over, everyone is prompted to pay!

Look at the gold coins, there are only 500, which is the entrepreneurial capital provided by the system to newbies. Pay 100 first?

"The set gold coins do not meet the needs of this research and development, please ask the host to add more gold coins."

200?...300?..500 are all given to you. Then...the submission is successful.

The system prompts that this research and development project has started.

Research and development content: materials, cast steel.

Equipment used: furnace...mold...

Consumable materials: iron... carbon... manganese... chromium... nickel...

Experimental batch: (first) time

Experiment record: The experimental environment is a smelting workshop, conducted under..., first... the metal... is... processed, then... cast... formed, and then...,

Then...finally...this experiment is over.

Experiment conclusion: The object of this experiment is metal materials, and the goal is to produce cast steel; the experimental process adopts smelting... casting and forging... annealing... and other processes; blast furnace... spreader... casting mold is used.

..; The material temperature control range is... to...℃, the experiment produces metal materials, 1 piece of cast steel (pseudo).

The relevant parameters are as follows:

(1) Shape: cylindrical, diameter 800mm, length 1870mm

(2) Element composition: fe, 75%; c, 0.12%; cr15.2%; mn6%; ni, 1%; ...

(3) Density (20℃, g/cm?3;): 7.93

(4)Yield degree (mpa):205

(5) Tensile strength (mpa):750

(7) Melting point (℃): 1398~1454

(8) Elongation: 35%

Experimental conclusion: This experiment is the beginning of the research and development of the project, and the number of times is the first in the first batch. Due to the vague description of the scene by the host, the records and data of this experimental process are unclear. The generated metal material has average hardness and strength; it has

It has a certain tensile force, has certain anti-wear, corrosion resistance, high temperature resistance, and good processing performance, and can be further processed into castings, profiles, plates, and wires. Please explore it in practice.

(Haha, I spent two hours in one class, but I still can’t figure out how to process this cast steel. The above index performance was compiled casually, please don’t take it seriously. I am studying literature and can only use fuzzy methods when writing science and engineering content. Readers

If you have any information, you can send it to the book review)

Extract this steel casting. This is a thin roll. If the shaft diameter is cut out, it may be useful.

Haha, looking at this cylindrical and long thing, Chen Lidong finally felt happy. These brain cells were not wasted.

However, this is not considered a product. He still has to turn this thing into a real roller. In fact, he can try using a lathe to process it.

However, if there is a system, we will not waste it. There is a lathe system, and the technology platform can also simulate scenes.

Next, don't be rash. Find someone who understands first to see if this thing can be used to make rollers.

If it doesn't work, we have experimental data and ask experts to look at the indicators and provide guidance. There are no talents in rural areas. After taking off, we have to form a team to do scientific research.

What's next? It's great again! It's my first experience, and I'm familiar with it again. However, when I submitted the order, I had no gold coins, and they had all been used up.

What should I exchange for? I suddenly found that in the system recycle bin, the exchangeable prices for each element element were displayed. For example, the most abundant element element, manganese, was 17 gold coins/kg; zinc, 21 gold coins/kg; and chromium, 78 gold coins/kg.

One kilogram of manganese is exchanged for 17 gold coins, and one ton is exchanged for 17,000 gold coins. Click to confirm, and the sound of getting gold coins is so sweet.

Haha, the problem that troubled Chen Lidong has been clarified. Where are the gold coins? Where are the gold coins? The gold coins are in the small dark room of the garbage station!

The system obtains corresponding materials (including basic composites and elemental elements) through material recycling. The composites can be embodied, and the elemental elements can be exchanged for gold coins. It's that simple.

He was reckless in the scientific experiment, and the problem of gold coins was solved. The next step, of course, is to speed up the recycling of materials, trade more gold coins to the system, then change equipment and produce products. If you have a system and can hack it, it depends on how you spend it.

In the blink of an eye, August is over and it’s September. At this time of year, the heat has subsided and it’s getting colder in the morning and evening.

A few days ago, Mr. Yu from Jishi got the treatment he deserved. Huaxi in the south also stepped onto the fast track under the leadership of Mr. Wu. Both Mr. Yu and Mr. Wu started out in steel, casting steel and rolling steel.

Machining. Also, Mr. Lu from Xiaoshan is also doing something big. Just this month, the Wanxiang Group he leads started issuing shares and is preparing to be listed in Pengcheng.

Three people are a model of entrepreneurship in this era. Since the beginning of this year, there has been a wave of climax. Some people were not sure enough and were thrown off the bus, while others were running on the right road.

This month, Chen Lidong and his family are also experiencing great changes. Chen's mother found that the small cash box at home could not fit in it. After hearing about Yu's story, she even discussed with Chen's father, "How about donating it to the country?", Chen's father said
