After the order was issued, the workers, led by their respective team leaders, began to build steel cages outside the foundation, and a small part of them were waiting for the order to be transferred.

Soon, the second and third trains arrived, and this time they were loaded with ten drilling equipment and 240 giant steel pipes with a length of 15 meters and a diameter of 1.5 meters.

Even the construction workers were shocked. 15 meters was almost the height of a four-story building, and such a height was just the foundation?

Soon, someone answered these questions with practical actions. Under the mobilization of the tower crane, ten drilling equipment were placed on the foundation that was compacted last night and operated according to the original plan.

At this time, the first drilling equipment started to drill wells in the place drawn with white lines in advance.

Soon, the first shaft appeared, and the tower crane immediately lifted the equipment to another position.

Just one minute after the shaft appeared, the tower crane lifted another 15-meter-long steel pipe and inserted it into it.

Then, after a surveyor measured the direction, the workers began to pour the steel pipes into the pre-mixed concrete and fill it until it was completely filled.

In this way, ten drilling machines were connected, and a shaft with a depth of 12 meters and a diameter of 1.5 meters would be drilled at every distance, and steel pipes would be quickly inserted and cement would be poured.

Two hours later, on the foundation of No. 1 blast furnace, 120 12-meter-deep shafts were drilled out, and the tower crane was hung with 15-meter steel pipes into the shaft in turn. At this time, the workers' steel cages were basically woven and placed in the pits in turn during the transfer of the tower crane.

Then, the surveyor quickly entered and after confirming that it was correct, he immediately began to weld the steel cage and steel pipe, and then poured the cement.

The cement required for blast furnace foundation is an astronomical figure. All around the blast furnace foundation are the sound of truck engines, and there are constantly trucks transporting raw materials back and forth.

Trucks of sand and trucks of cement are constantly unloaded around, and after mixing, they are quickly thrown into the pit.

The cement this time is different from the cement on the tower crane base. The condensation speed is much slower than the last time. It takes six hours to produce a strength of 60mpa. It belongs to the slightly slower type of fast-drying cement.

The foundation of the first blast furnace was basically completed, and the sound of firecrackers sounded, and the workers immediately switched to the second blast furnace and the third blast furnace.

As night falls, the three blast furnaces are basically completed. Why not come again tomorrow? They will have to deal with the remaining sintering furnace foundation, a coke oven foundation, a hot air furnace foundation, and a cold air furnace foundation.

Oh, by the way, there are two fertilizer workshops next to it. The phosphorus elements in the slag will be processed into fertilizer and sold by the fertilizer workshop.

After thinking about it carefully, the first thing that needs to be solved at this time is refractory materials. Why plan to go to another 20,000 people to work tomorrow and then solve the refractory materials problem for the rest of today.

Refractory materials are undoubtedly very important. Blast furnaces are not built with only one type of refractory material. They need to be used in combination with different refractory materials. The blast furnaces built now require at least five categories, so we have to check the firing progress.

If difficulties are encountered during the firing process, the construction period will be delayed and you must prepare in advance.

For easy transportation, a temporary workshop for firing refractory bricks and powdered refractory materials is not far from here.

In addition, the new type of refractory brick adopts a splicing structure. After firing, it can be quickly spliced ​​into a 5-ton large piece and hoisted.

As for firing refractory kilns, He Ku didn't know how it was built. His old skills in planting flowers were to burn porcelain and bricks. These didn't require him to do so. His mind was not here, but mainly on the steelmaking furnace.

The first batch of refractory bricks started to be tested yesterday afternoon. Now, after a day and night in high temperatures, the furnace can be opened and tested immediately.

In the next time, He Ku went to the powdered refractory workshop to take a look. He didn’t let them burn in large quantities until the powdered refractory products were fully inspected and passed the inspection!

Then, He Ku stood next to the brick kiln and stared for a while, and immediately a worker noticed him.

"General Manager He, do you want to open a kiln?" A worker came to He Ku's side and asked.

"Drive, be careful and be sure to pay attention to safety." He Ku said, reminding the worker.

"I know, General Manager He will definitely succeed. Experts from the Qing Dynasty have come to see it and they all say it will work!" The worker said to He Ku with a smile.

"I'm sorry for you. But don't let the messy brick house visit here in the future, unless you are a brother unit that has issued certificates from our factory. Who knows if the person who came is a real brick house?" He said with a wry smile, and admired those people very much. He didn't know the recipe. After looking at the kiln, he could confirm that it would be successful.

"Yes, General Manager He!" The workers heard this and responded, and immediately prepared for the preparations before opening the kiln.

After a while of preparation, the kiln was about to start opening the kiln. He Ku took the technicians away from here. After opening the kiln, a wave of heat rushed from it. Although He Ku was far away, he also felt a little uncomfortable.

In fact, more than an hour ago, the ten brick kilns here were turned off, but they kept cooling down. After a hot air, the temperature in the kiln was basically only about one hundred degrees left.

"Leave here first, hurry up, stand far away, and then open the hole wider!" The workers shouted on both sides of the kiln, opening the entire brick kiln bit by bit.

When the first car of bricks was pulled out, someone immediately went up to perform the test. After a moment, the workers shouted excitedly, "General Engineer He, General Engineer He, have done it, have done it, the bricks inside meet the standards!"

He Ku was also very excited when he heard this and shouted quickly, "Very good, I'll send some samples to the steel rolling mill tomorrow!"

After a while, a worker came over with a duck and a lion-like porcelain.

"General Manager He, why did you burn a duck and a lion?"

He Ku said embarrassedly: "This is the mascot of our factory, Pili Duck and Jingshi!"

"it's beautiful!"

When the workers heard this, they looked carefully and praised them.

They have never seen such animals, such as ducks and lions wearing clothes, hats, and makeup.

He Ku put away the two cartoon mascots and instructed: "Okay, let's start trying out the assembly and see if our ancestral mortise and tenon structure can make the bricks assembled together."

After about three minutes, the workers spliced ​​the bricks together. Because of the mortise and tenon structure, even if they were hung, they would not fall apart and were very strong.

In this way, why not use this as the isolation layer and place it in the middle of the steel plates and iron plates on both sides of the blast furnace, and pour different refractory materials on both sides, saving a lot of time.

After reading the quality inspection reports of all products, He Ku immediately issued a production order, "Yes, stock up today's ones! Start firing in large quantities now, and you will use them tomorrow!"
Chapter completed!
