After returning from the old site of the steel plant, Cao Weidong pushed all the affairs of the biogas plant to several directors, and plunged into the steel plant himself.
He leaves early every day and comes home late every day. He is mysterious and does not tell others what he is doing.
This aroused the suspicion of Chen Xueru and Ding Qiunan.
But no matter how the two women asked, Cao Weidong just didn't say anything.
This guy...
You won’t find another sister for them, right?
The two women felt a sense of crisis and decided to secretly follow Cao Weidong.
But they followed Cao Weidong all the way to the steel factory.
It was discovered that Cao Weidong did not do anything extraordinary.
Just get into the concierge where the original concierge lived.
While drinking tea from a teapot, I read a book with a Buddhist smile on my face.
Ding Qiunan was a little confused.
"Did our brother Wei Dong change his gender and start drinking tea, studying, and cultivating his moral character?"
"Bah, can he cultivate his moral character?"
Chen Xueru spat.
Thinking of Cao Weidong's bravery in playing songs every night, Chen Xueru suddenly shook his head like a rattle.
Ding Qiunan pointed it out to Chen Xueru.
"But...but Wei Dong is just reading a book. Look how seriously he reads, and there is a smile on his face like an epiphany."
Chen Xueru was immediately speechless.
Facts speak louder than words.
At this moment, Cao Weidong was sitting in the gatehouse of the steel factory, reading quietly.
Just like the scholars in ancient times who went to the ancient temples in the mountains to drink tea and study for the sake of purity.
The two women thought about it, but they were still a little worried.
They simply observed for one more day.
But in the end we could only accept the fact that "Cao Weidong went to the steel factory to be lazy".
Now that we "know" that Cao Weidong is "safe".
The two women decided to end this meaningless stalking.
They are also very busy.
Ding Qiunan is now the director of the health center of the biogas plant.
There are major and minor matters in the hospital, and she basically needs to handle them when approving purchases.
Moreover, a literary and artistic propaganda team was established.
Ding Qiunan is the captain of the literary propaganda team.
Now the literary and art propaganda team is rehearsing intensively, preparing to perform for employees on Labor Day.
So Ding Qiunan still needs to attend rehearsals after get off work.
Of course, Chen Xueru was not idle either.
Under the recommendation of Cao Weidong, Chen Xueru met with Yinghua, the director of the textile factory. The two hit it off and reached an intention to cooperate.
Chen Xueru placed the order and Yingyinghua was responsible for producing it.
It just so happens that the textile factory has ready-made tailors.
So Chen Xueru basically spends these days in the textile factory, talking with tailors about the styles of sample clothes and suggestions for modifications.
.......
Realizing that the two women were completely gone, Cao Weidong breathed a sigh of relief.
In fact, he had long discovered that Chen Xueru and Ding Qiunan were lamely following them.
However, in order to get rid of the two women as soon as possible, Cao Weidong simply used the trick and pretended not to notice.
Seeing that the plan was completed, he stopped pretending.
I threw the two books [Young Ajun] and [Young Woman Angelica] that I exchanged from the Wanjie Mall aside, then drank the wolfberry water in the tea vat, turned around and got into the portable space.
At this time, the appearance of the portable space has completely changed.
An open-air blast furnace workshop appeared out of thin air near the warehouse.
The huge blast furnace is rumbling, with chimneys, hot blast furnaces, feeding belt carts, etc. all nearby.
And right in front of the blast furnace, there are still a lot of slag piled up.
"I didn't expect this to be..."
Cao Weidong looked at the blast furnace in front of him, with a flash of shock in his eyes.
In fact, the process of moving the iron-making blast furnace of the steel plant into the portable space is very simple, even simpler than he imagined.
After sending the janitor away, Cao Weidong sneaked into the iron-making blast furnace and touched the iron-making blast furnace with his palm, wondering how to move this big guy into his personal space.
Who knows that the heart can move at will.
At that moment, the real-life iron-making blast furnace collapsed and was destroyed.
And in my personal space, this blast furnace workshop appeared out of thin air.
This feeling is as if the spirit of this iron-making blast furnace in reality has entered the portable space, and the physical body remaining outside naturally decays and collapses.
"It's like a miracle..."
"Forget it, let's stop thinking about it and start refining rare metals."
Cao Weidong calmed down and started the blast furnace.
Truck after truck of slag is sent to the blast furnace through a conveyor belt.
The blast furnace hums and begins to operate.
At the same time, a progress bar popped up next to Cao Weidong.
It shows the success rate and estimated time of forging rare metals.
Seeing that it was still early, he simply took a fishing rod and ran to a small lake not far away to fish.
........
Several hours passed in a flash.
Just when the bucket next to Cao Weidong was almost full of fish, the system prompted that the blast furnace had completed calcining.
Cao Weidong poured all the fish in the bucket back into the lake, and then returned to the front of the blast furnace workshop.
The black slag on the empty space has disappeared, replaced by silver metal blocks stacked together.
It's as bright as silver.
[Ding, you have discovered that the iron ore associated mineral - vanadium-titanium magnetite, has been calcined to produce 157 pure titanium ingots, 121 pure vanadium ingots, 59 vanadium-titanium alloys, and 3 special metal memory alloys.]
[The blast furnace has recorded the forging recipe: titanium ingot.]
[The blast furnace has recorded the forging recipe: vanadium ingot.]
[The blast furnace has recorded forging formula: vanadium-titanium alloy.]
[The blast furnace has recorded the forging recipe: memory alloy.]
"It's actually vanadium-titanium magnetite?"
Cao Weidong felt a little surprised at first, but then he felt relieved. Instead, he felt that this was a matter of course.
Vanadium titanium magnetite is a composite iron ore composed mainly of iron, titanium and vanadium elements, and symbiotic with a variety of valuable elements.
This kind of ore often appears as an associated ore of iron ore.
Moreover, vanadium-titanium magnetite is one of the ores that is difficult to smelt, commonly known as dead ore.
During the smelting process, a series of adverse effects are often produced on the operation inside the furnace and the treatment of slag iron outside the furnace.
Now that I think about it, perhaps it is because of these vanadium-titanium magnetites that the steel plant has poor production efficiency and poor product quality.
】
In addition, my country is a country with large vanadium and titanium resources, which mainly exist in the form of associated minerals in vanadium-titanium magnetite, and their distribution is concentrated in Sichuan and Hebei.
Wan'an County is close to Sijiucheng, and the smelted iron ore comes from surrounding mines. It is a matter of course that the iron ore is mixed with vanadium-titanium magnetite.
Cao Weidong figured it all out, stroking the pieces of silver metal and muttering to himself.
"These are all treasures, and their value is definitely not inferior to the same gold."
Vanadium is known as the "monosodium glutamate of modern industry" and is widely used in steel, chemical industry, aerospace and other fields.
Titanium is called a "strategic metal". Titanium and its alloys have excellent properties such as corrosion resistance, high strength, good high and low temperature strength, non-magnetic, good adaptability to the human body, shape memory and superconductivity.
Due to its light weight and high strength, it has been widely used in aerospace and other fields.
In addition, it is also used in civil industrial fields such as shipbuilding, petrochemical equipment, offshore platforms, power equipment, medical care, and high-end consumer goods.
As a composite metal, vanadium-titanium alloy also has the characteristics of high strength and high toughness.
Using these special metals in the forging of biogas generator parts can definitely solve the problems of soft metal and brittle steel.
In addition to these three special metals, Cao Weidong is most interested in the "memory alloy".
