Return to the exciting era of 1999

Chapter 209 The Biggest Order of April
"But my sister also reminds you that foreigners can't believe all of them. These people come to us just to make money, and they will never tell you friendship!"

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

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

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

"What the hell, the water in any company is so deep, it almost drowned me! Alas, it's hard to be an ordinary person, and it's also hard to be a manager of a company. These days... damn, I'm still a man!"

"Buzz!"

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

Ji Donglai was drinking recklessly. He spent a lot of energy dealing with the golden-haired animal Ji Donglai these days, and now is the time to relax.

"Boss, we have a big job here. You can see if we can do some things. I dare not make a decision. After all, I don't understand polymers!"

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

"Okay, I'll be there right away...the waiter packs and brings me two more dishes!"

Da Qizi didn't look for him easily, so Ji Donglai immediately asked the waiter to order some dishes for him, and then took a taxi back to the small factory.

"Damn it, it's really a big job."

The product comes down from the power plant, the huge rubber roller of the conveyor belt!There is no problem with the big Qizi in the middle of the steel rod core, but the rubber lagging is not easy to handle, requiring wear resistance.

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

"Master Qi, make the steel rods, the one with the lowest cost, give me the combined price, and then make the glue! Ai Xing, come here, we use the stove as an oven..."

Ji Dong came to Ding Aixing to start assigning tasks, and started to place orders for rubber manufacturers. The surface was a polyurethane wear-resistant layer, [-] degrees, and three thicknesses.

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

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

The cylinder was made of refractory material internally. Ji Dong came to Cao Ren and went to Dacheng to directly find someone to make it. Because they were all standard models, Cao Ren sent the refractory cylinder over in one day.

Drive motor, rollers on both sides, blocked.

Every item has been calculated in detail by Da Qizi, Ji Donglai and He Xiaolong lead people to make it, and Ji Donglai arranges people to produce electronic drawings.

The joints of the refractory cylinders are made of refractory glue mixed with cement. After all completion, asbestos ropes are wrapped outside for heat preservation, and finally the cylinder is wrapped, followed by a [-]-thick ring liner track.

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

After everything is done, the entire centrifugal cylinder starts to be processed on the lathe.The head first drills a top hole, and then welds an optical shaft on the back. With the lathe gradually aligning, iron filings start to fly.

"Don't make the car too light, it's [-]:[-], otherwise the gears won't catch it!"

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

The chief turner held the enamel jar and looked at the newest young apprentices who kept telling him, the little worker immediately changed the turning speed, and Ji Donglai kept nodding.

The welder over there welded a V-shaped frame with channel steel according to Ji Donglai's design drawings. Steel rollers matched with two acceleration gears and four-stage motors completed the entire mechanism.

The gantry crane started slowly, and the whole mechanism was swayed by the crane and installed on the deceleration mechanism. With Ji Donglai starting the motor, the speed of the whole deceleration mechanism gradually increased.

"It's ok, load the stove, one hundred kilograms of ingredients, add according to this ratio!"

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

The shaft head is welded with 45, and a rib plate is added inside.

"call……"

All the scrap iron weighed by the electronic scale was thrown into the intermediate frequency furnace, and the hot flame rose to a height of half a meter. The worker took off his gloves and wiped the sweat from his forehead. Da Qizi looked at his watch and returned to the lounge to drink water. The rest of the workers looked at the stove.

After an hour, Da Qizi put down the water tank and walked out of the office, put on his sunglasses and walked to the bottom of the steps. If the big pole was stretched over, Xiaogong opened the lower discharge port, flicked the dross in the discharge port, and a stream of bright red molten iron flowed out. come out.

"Shh!"

An iron flower flew out, Ji Donglai gave a thumbs up, and raised the flower to see the carbon content, which is a skill only experienced technicians have.

"Release the material, hit fast!"

"Good master!"

Looking at the color of the iron flower, Da Qizi said hello, the little apprentice activated the electronic button, and the furnace began to slowly discharge the material. With the valve closed, several workers carried the material cylinder to the front of the roller.

As the molten iron enters the drum, a burst of white smoke comes out.

With the gradual addition of molten iron, the speed of the entire drum decreased, and Da Qizi started the backup reducer, and the rotation speed of the drum accelerated again.

"Shhhhh!"

"The stove continues to add ingredients, and the drum comes out of the pan!"

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

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

"Damn it, it's so beautiful. It's the first time I know that the roller can be shaped like this. It's a good experience!"

"Brother Donglai, is this structure dense enough?"

"Yeah, isn't it hard enough to cast?"

Looking at the bright red cylinder, the eyes of several students were full of admiration, but also full of doubts.

"Centrifugal casting, check the books! This craft is now and very few people know how to do it, don't look at the school where you study it, in fact? Many practical things are gradually lost! The so-called education does not conform to the development of the times. That's it!"

"The probability of centrifugal force throwing molten iron out is the same. This casting method produces the most uniform product quality, so don't worry about compactness! Besides, if we want to be more dense, we can actually go to the forging platform and continue forging in this shape. Grain structure!"

"But this small roller doesn't need to be so strenuous. Its function is only transmission, not real force!"

The iron block on the side of the intermediate frequency furnace is still melting, and the shaft head steel rods on both sides are also heated red at this time.The surface of the iron rod began to turn white, and the worker turned off the power to the coil, and the whole steel rod was sent into the punching machine.

"Empty and empty..."

With the heavy head smashing down, the steps of the shaft head slowly formed.
