"But my sister also reminds you that foreigners can't believe it all, these people are only here to make money, and they will never tell you about friendship!"

Hu Xinyu is worthy of being an antique-level boss of a large company, and she can see Ji Donglai's worries at a glance, which makes Ji Donglai embarrassed.

Sitting in front of the other party, Ji Donglai felt that his heart could be seen through by the other party at a glance.

The taste of this meal can be imagined, Hu Xinyu just ate two bites and left, Xu Gui also left, only Ji Donglai was left to let go.

"Damn, the water in any business is so deep that it almost drowned me! Alas, it is difficult to be a flat-headed ordinary person, and it is also difficult to manage a company...... Damn, I'm still a man!"

"Buzz!"

"Huh? Master Qi, what's going on?"

Ji Donglai is drinking recklessly, it has taken a lot of energy to deal with the golden retriever beast Ji Donglai in the past few days, and now is the time to relax.

"Boss, we have a little bit of work, there are some things you can see if we can do it, I don't dare to make a decision, after all, I don't understand polymers!"

Da Qizi scratched his head, including the master of machining, who was already in trouble at this time.

"Okay, I'll be right there...... The waiter packed it and brought me two more dishes!"

Da Qizi easily didn't look for himself, Ji Donglai immediately beckoned the waiter to get him a few dishes, and then took a taxi and returned directly to the small factory.

"I'm going to it, it's really a big job."

The product is a huge rubber roller from the power plant! The inner core of the steel rod in the middle is no problem, but the rubber is not easy to get and requires wear resistance.

Moreover, the lagging conditions are required, and the construction period is one month if the surface is textured.

"Master Qi, make the steel rod, make it at the lowest cost, give it to me at the price, and then get the glue!" Ai Xing, come here, we use the stove to make an oven here......

Ji Dong came to Ding Aixing to start arranging tasks, and began to place orders for rubber manufacturers, the surface is a polyurethane wear-resistant layer, 80 degrees, and three thicknesses.

On the surface of the roller, Ji Donglai asked his hand to roll a cylinder, divided into two halves, polished inside, and locked with bolts between the two halves of the mold.

Da Qizi's side is also busy now, according to Da Qizi's requirements, it is similar to Ji Donglai, and Da Qizi's side has also made a two-half mold.

The interior is made of refractory materials, and Ji Dong came to Cao Ren to go to Dacheng to find someone to do it directly, because they are all standard models, Cao Ren sent the refractory cylinder over in one day.

Drive motor, double-sided rollers, plugging.

Everything has been calculated in detail by Daqizi, Ji Dong came to He Xiaolong's side to bring people to make it, and Ji Dong came to arrange people to produce electronic drawings.

The refractory cylinder connection is made of refractory glue mixed with cement after all is completed, the outside is wrapped with asbestos rope for insulation, and finally the cylinder is wrapped, followed by the lining track of the 20-thickness ring.

"On the lathe, remember to ensure concentricity and surface polishing!"

After everything is done, the entire centrifuge cylinder begins to be processed on the lathe. The head first drills a top hole, and then welds a smooth shaft on the back, and the iron filings begin to fly as the lathe gradually aligns.

"Don't be too light in the car, just 6:3, otherwise the gears won't be able to catch!"

Looking at the group of people under him, Ji Donglai nodded secretly, his subordinates are finally ready now.

The chief lathe looked at the latest few little apprentices with the enamel jar and kept admonishing, the little worker immediately changed the turning speed, and Ji Donglai kept nodding.

The welder welded a V-frame with channel steel according to Ji Donglai's design drawings, and the steel rollers were matched with two acceleration gears and a four-stage motor, and the whole mechanism was completed.

The gantry crane started slowly, and the whole mechanism was swayed by the crane and installed on the deceleration mechanism, accompanied by Ji Donglai to start the motor, and the speed of the entire deceleration mechanism slowly became faster.

"It's okay, stove feeding, 100 kilograms of material, add it in this proportion!"

According to the requirements of the power plant, it is 45 materials, in fact, it is not used at all, and the foundry directly uses Q235 to adjust it, and the carbon content is slightly higher.

The axle head adopts 45

Welding, adding a rib plate inside.

"Hoo ......"

All the scrap iron weighed by the electronic scale was thrown into the intermediate frequency furnace, the blazing flame jumped up half a meter high, the worker took off his gloves to wipe the beads of sweat on his forehead, Daqizi looked at his watch, returned to the lounge and began to drink water, and the rest of the workers looked at the stove.

An hour, Da Qizi put down the water tank and walked out of the office, put on sunglasses and walked to the bottom of the steps, if the big pole stretched out, the worker opened the lower discharge port, dialed the dregs of the discharge port, and a stream of red molten iron slipped out.

"Whew!"

An iron flower flew out, Ji Donglai gave a thumbs up, and raised the flower to see the carbon content, a skill that only an old mechanic has.

"Release, play fast!"

"Okay master!"

Looking at the color of the iron flower, Da Qizi said hello, the little apprentice started the electronic button, the furnace began to slowly release the material, and with the valve closed, several workers carried the barrel to the drum.

As the molten iron entered the drum, a puff of white smoke came out.

With the gradual addition of molten iron, the speed of the whole drum decreased, and Daqizi started the standby reducer, and the rotation speed of the drum accelerated again.

"Whew!"

"The stove continues to be filled, and the drum is out of the pot!"

After the molten iron was added, Da Qizi waved his hand at the intermediate frequency furnace, and the little apprentices continued to use the electronic scale to start weighing and feeding, and the speed of the drum here slowly decreased.

Then the crane lifts the drum, one side is blocked and opened, and with the inclination of the drum, a bright red cylinder slides out of the drum.

"I'll it, it's so beautiful, it's the first time I've known that the drum can be shaped like this, I've seen it for a long time!"

"Brother Donglai, is this structure dense enough?"

"yes, it's enough to be cast, right?"

Looking at the red body, several students were full of admiration in their eyes, and at the same time full of questions.

"Centrifugal casting, check the book! This craft is now being done by few people, don't look at you learning it at school, in fact? A lot of useful things are gradually being lost! The so-called education is not in line with the development of the times, and this is what it says!"

"The probability of centrifugal force throwing the molten iron out is the same, and the quality of the product obtained by this casting method is the most uniform, so there is no need to worry about the compactness! Besides, if we want to be more solid, we can actually go up to the forging platform and continue forging in this shape to change the grain structure!"

"But this little roller is not so strenuous, the effect is only transmission, not the real force!"

The iron on the side of the intermediate frequency furnace is still melting, and the steel rods on both sides of the shaft head are also heated red at this time. The surface of the iron rod began to turn white, the workers de-energized the coil, and the entire steel rod was fed into the press.

"Empty ......"

With heavy head-to-head smashing, the staircase of the shaft head slowly forms.
