Chapter 210: Sand Cast
The next day, May 27.
Heat fumigation.
Fiery sunlight spills down from the sky, smelting the green tiles.
Hongqi carried a bag of vermilion waste, reluctantly walked out of the shady stable, and was led out of the Asahi Mansion by his master.
Taking advantage of Hong Pan's relationship, Hong Fan found a blacksmith shop in Xijing City and borrowed a small blast furnace.
It's hot.
Even hotter is the charcoal fire.
In the furnace room, the two shirtless apprentices stirred up the bellows with all their might, sweating like pulp.
In their envious gaze, Hong Fan, who was dressed in military uniform, was standing peacefully facing the furnace.
When the Yanliu Gong is practiced to the middle of the Turbulent Section, the True Qi can reach a high temperature of 800 degrees.
That's why Hong Fan regards the scorching heat as nothing, obviously wearing formal clothes, but he doesn't sweat a drop.
After a few moments, the golden-red molten iron boiled out.
Hong Fan thanked a few helpers with broken silver, emptied the room, and began the final casting work.
This step is the easiest.
Hong Fan took a large stream of barren sand from outside the door, which gathered into a spoon shape.
He then controls the sand spoon to insert the molten iron and scoop up a cloud of gold liquid.
Metal casting is said to be pouring molten iron into a mold, but there are actually many difficulties.
For example, surface defects, holes, cracks, segregation (uneven distribution during crystallization), etc., need to take into account the size effect and the problems of solidification, shrinkage, stress, etc.
Changing to a local blacksmith, even if there are high-precision drawings provided by Hong Fan, it is impossible to cast a usable high-precision separator.
But in the face of the sand world, none of this is a problem.
The barren sand deforms, wraps the molten iron, and then gradually expands.
The sand crust is so light and thin that you can see the color of fire (the melting point of sand is 200 degrees higher than that of iron).
Under Hong Fan's control, the separator was quickly shaped.
There are no cavities, no condensation, because the mold is alive.
Under the guidance of the sand, where the molten iron goes, whether it fits the surface, Hong Fan is clear.
He then selectively removed the castings from the furnace to control the cooling and prevent shrinkage defects (7.13 for 7.13 and 7.8 for iron).
After a short while, the whole process ended.
Hong Fan wiped his sweat and removed the fine sand.
The complete cyclone separator is formed in one piece, sitting firmly on the stone platform.
There was no welding, not a single screw or rivet, as if the steel was born to look like this.
Hong Fan stepped forward to carefully inspect and confirmed that there were no defects inside and outside the device, only some of the surfaces were slightly rough.
Next is sanding.
The fine sand forms a grinding wheel, which spins in the air and shoots a large handful of sparks.
Half an hour later, all surfaces of the separator have been treated, and the light is visible.
Everything went smoothly.
Hong Fan brought the bag of scrap for a final inspection.
Take clean water from the water tank in the furnace room, and then use sand as an urn and Yanliu true gas as fire, and distill it on the spot.
Pour the lavender waste powder into purified water and stir into a homogeneous suspension.
Then pour into the inlet.
Hong Fan turns the shaker and drives the impeller.
The water roared, but it couldn't drown out the sound of his heartbeat.
The first filtration was done quickly, and a lot of wet wood chips fell in the ash hopper under the separator.
But that's not enough.
It is repeatedly dissolved and separated three times with pure water, and finally the vermilion powder left by evaporation is uniform in color, which is better than the goods from yesterday's sand mold.
"Whew."
Hong Fan let out a long breath and carefully wrapped Zhu Zi in clean white silk.
He also wrapped the separator with linen cloth until he could not see the shape, and then he took it out of the furnace room and put it on the back of the red flag.
Thanks to the owner of the blacksmith shop, one man and one horse took to the streets.
It was close to noon, but the sun was not as warm as it had been earlier.
The heavy cloud giant came to the sky over Xijing, carrying with it the thunder and lightning of its grazing.
Bang......
The rain poured down in an instant.
Residents cursed for closing stalls, collecting clothes, and closing windows.
Passers-by who did not bring umbrellas hurriedly looked for enough rain to take shelter.
Throughout the long street, only the red flag and its owner are not in chaos.
Hong Fan covered his chest, and the sand protected the white silk.
Crash......
The heavy rain is like white air rising from the ground, blankly isolating the world.
Hong Fan walked in the rain, listening to the white noise that alienated everything in his ears, and his brain, which had been tense for several days, finally relaxed.
People walk on the streets, but their hearts fly out of Xijing.
According to the letter received yesterday, Aunt Liu and Tang Da have already driven Bentley out of Jinhai.
Soon, Asahi will truly become home.
Soon, the Jin Haihong clan will never worry about the marrow cleansing pill again.
······
May 28.
He Zhixin, who has always been busy with affairs, rarely slept lazily.
At nine o'clock in the morning, he walked to the outer hall with his waist stretched and dressed in clogs, and sat down cross-legged on a single cushioned seat.
The maid handed over a toothbrush with bristles and ivory handles stained with gastrodia agarwood powder.
He took it, rinsed his mouth with tea, and began to brush his teeth.
At this time, He Zhixin saw a white silk package on the table of the single seat, and the fold was sealed with wax.
"Something, nondescript."
He frowned and muttered, asking.
"Where did this come from?"
"It was sent back by the guest you saw last time."
Those who waited outside the door often bowed and replied.
"Oh."
He Zhixin muttered, brushing his teeth while unwrapping the layered silk cloth.
There's some fine powder coming out of it.
Lilac, very pure.
"What?"
He Zhixin slightly activated his mind that had just woken up and was still idling, and twisted the powder with his hands.
The tentacles are not soft and glutinous like flour, but have a prickly feeling from very small grains.
He Zhixin's face became serious.
"You just said, who sent this thing?"
He suddenly looked up and asked, the words were round.
"Hong Fan Hong Gongzi in Xijing City, the one you received before."
Always follow the return.
He Zhixin was completely stunned.
After a moment, he took a deep breath and carefully twisted some crystal powder, smelling it before tasting it.
Smack.
The expensive ivory toothbrush fell to the ground, and the maid felt a pain in her heart.
But He Zhixin didn't realize it, but swallowed his saliva unconsciously, and actually swallowed most of the toothbrush powder.
He couldn't even care about nausea anymore.
"Little Liu, come here!"
He Zhixin ordered.
Chang Sui outside the door rarely saw the master so cautious, and hurriedly ran over.
"Do you smell anything?"
He Zhixin put his fingers stained with crystal powder to the end of his nose.
"No, no ......"
Xiao Liu replied.
"No?!"
He Zhixin snorted, as if surprised and delighted.
But Chang Sui was taken aback, so he had to sniff and distinguish again.
"Ah, no? Uh, it seems to have a ......"
"Is there any?"
He Zhixin asked in a deep voice.
"Is there a smell of cicadas without chirping?!"
"Second master, I didn't smell the cicada without a song, but it was a little sour, and there was a little honey fragrance......"
Xiao Liu carefully distinguished, and was so anxious that he was about to cry.
"You're pretty smart."
He Zhixin sneered and calmed down.
"The sour taste is gastrodia, and the honey fragrance is agarwood!"
"But there is no woody fragrance of cicadas without song......"
He muttered to himself, covered the white silk back, and commanded.
"Get me a car!"
Xiao Liu had just gone out of the door, and he was drunk again.
"No, don't have a car, prepare a horse for me, I want the fastest!"
He Zhixin finished speaking like a storm, picked up the clogs, and rushed back to the room regardless of the left and right.
