After an arduous trek all afternoon, after returning to the studio from the limestone mining area, Polu recorded his calculations in a small notebook.
There is no doubt that if you want to produce cement mortar, the first thing is to mine a large amount of ores. The second thing is to grind them into fine pieces. The third thing is to burn them. The fourth thing is to grind them again. The fourth thing is to grind them again.
Five things to bring back.
There is no hope of rebuilding Hongshan by the hands of craftsmen. What is needed now is cold, ruthless, and creaking large-scale machinery and equipment. However, the biggest problem now is actually traffic. As soon as you leave the road, you will immediately fall into chest-high thatch.
Or other grass. It is very difficult to walk in, let alone transport machinery and equipment in, and then transport the produced cement out.
If you want to be rich, you must first build roads and inspire enlightenment! Only then did Polu truly realize the urgency of being forced to become an infrastructure fanatic.
Now we need truly powerful means of transportation. In such a vast wasteland that is not even considered grassland, there is no future for roadbeds that do not protrude from the ground! The tractor experiment has been successful, and it is good to install it on the track.
transportation power, plus several truck bodies,
The familiar smell is back! It's time for Mercedes-Benz steam engines to rule this unexplored land! The worst thing you can do is drive a little slower. And this requires a lot of steel, so the small experimental furnace can no longer meet the demand, so we need to
Build a new furnace, so you need new raw materials.
Trapped/in/dead/tangled!
Polu sighed: "Well, history is indeed an upward spiral, and materials have to grow in a spiral. Only by increasing the output of one stage can the next increase of output be promoted. Come in line and get the ore out of the mountains first. If you don't do it,
We can’t even afford the small stove.”
Because the tractors diverted a large number of ore carts, the horses got a long-awaited rest. However, the volume of ore transportation dropped. But Polu planned to let the horses completely change their jobs. Many things that needed to be transported flexibly were waiting for them, and the heavy ones were waiting for them.
Leave the ore to the steam tractor running on the track!
Soon, Polu made a clay model, and when everyone reached an agreement, construction could begin! Now the planned location of the building has even been dug, but the foundation has been dug out, but the work has stalled because there is no cement. Simply put those young people
Let's all move in to build roads and make stoves. Polu opened the door of the studio and walked into the night outside.
The next day, he began to explain the new plan to Irene, Leah, Landau and Svitto who were sitting in front of him.
"Look, this is the old town of Hongshan. Because it happens to be blocking the road coming down from the mountain, the insect beasts are smashing down at the speed of going down the mountain. They can't stop it. Anyway, the old site of Hongshan can't be stopped now.
, we might as well turn it into a mine dump."
Erin disputes this: "Do you really need such a large ore dump?"
"It may not be necessary, but we can no longer let people live so close to the risk of attack. This area has all been converted into mining sites, leaving no one behind. I believe the insect beasts have no interest in iron ore.
You can't live by eating iron ore even if you are interested." Bolu ordered the sand tray.
"This road was once the transportation road in the center of Hongshan Mountain. It was the natural choice of carriage masters. In fact, it is the closest and smoothest road. I plan to rebuild the ore transportation track here. It is right in the center of the ore dump, and the operation
It’s also very convenient to get up.”
"This area is a factory for supporting the new blast furnace."
"A new factory? Wait! Why do we need to keep such a big area! So many models? What are you going to do!" Little Eileen sensitively realized the problem!
"The old furnace is really not enough and we can't do it without expanding it." Polu said sincerely.
Little Irene looked at him with a critical eye until Lang Dao said, "What he said is true. Our steel production capacity has indeed reached a bottleneck. It does need to be improved."
"I finally made money, and now I have to spend it again! Then you guarantee that you can make the money back?" Landau's authority seemed to be useful, and little Irene gave in.
"I promise! I promise! We can sell at least 5,000 gun tips every month! I promise you!" Polu quickly answered.
"I just came back after negotiating a long-term supply and sales contract for you!! At least 3,000 gun tips per month! If you miss one, you will not be able to make new things in the future!"
Little Irene left the room angrily. Leah, who had been silent and seemed to be thinking about something, said: "Don't blame her. You spent money too fast. She may be a little nervous. I'm a little busy recently and don't have time for the moment."
I'll go around the construction site with you, you should be busy first, I still have training and go back first."
Only Poru and Landau were left in the studio.
"Teacher, is your crystal experiment going well?"
"It's okay. I seem to have some inspiration. You should be busy first. I have experiments to go back to." Landau stood up and left the room.
"?" Bolu stretched out his hand, opened his mouth, and looked at their leaving figures, but couldn't say anything.
Polu explained clearly to the engineering team leaders their next work content in Father Peter's office.
With the strength of the people and the strength, a large amount of waste materials were soon piled up as roadbed. 30 engineering teams were busy on the road. They pushed out the building ruins with trolleys from the ruins on both sides of the road, and then piled them on a 5-meter-wide road.
, in an area with a height of 3 meters, and then add clay and compact it. I don’t dare to think about sleepers.
There were so many sleepers that they would cut down the nearby mountains. Poru was afraid that when the elf transport team came, he would see the bare tree stumps and cut his own head into a stump in anger. Otherwise, he would just go ahead and cut it into a stump.
Let’s install molded cement sleepers. It’s been so long, why haven’t you returned? Could it be that they were out of order?
"If you don't come back, Edith, I will sell your order to Nazwa!" Polu thought fiercely in his heart.
Soon, the engineering team entered the new factory area that had been marked out on the ground with lime. Judging from Polu's planning map, this area occupied exactly the size of four basic grids. From the grid of the residential area
After counting the grids, there were 10 grids separated. Although the residential area still only had a foundation, the location was at least determined. They began to dig a huge deep pit! They also used slag cement and various crushed stones.
Fill this pit!
Goola and Smith have been having a splitting headache recently. Although tractor production is currently only workshop-style and has been handed over to Case for management, Polu has put forward a bunch of new demands!
At the moment, the three of them are in a small open area where materials are piled, worrying about a 3-meter-high scaled wooden model.
After listening to Polu's explanation, Geola looked worried, "Little manager, why is your model of the stove so big? The stove we used before was only this big! 30 meters high! More than 10 meters thick! No one has ever made one before.
!No, I’ve never even heard of it! What kind of monster is this!”
"How are we going to produce these accessories?" Smith also looked worried when faced with some strange-shaped parts.
"That's right, it's true that we haven't done it before, but we have to create something that others haven't created before. Don't you want to use such a big stove!" Although Polu felt guilty, he still encouraged everyone. If everyone was scared,
This furnace can no longer be built!
"Isn't it just a big furnace? Although the structure is a bit complicated, if it doesn't work well, we may have to rebuild it and renovate it several times." Polu looked around to avoid Irene hearing this statement.
"Speaking of which, we have been using copper. How much copper is there in stock in the factory?"
"There's quite a lot of it. The ore that was shipped was sometimes mixed with a lot of copper ore. Once we saved it, we used a small furnace to smelt it. In the past, the more ore was used, the more copper was produced faster than it was consumed, and the more copper was used, the more it was used.
More and more!"
"?? This is the first time I've heard that we have copper here. How much is it? That's great! At least one problem is solved! Are our refractory bricks still being made? It's okay. Let's pick it up again."
Soon, the workers of the Hongjian No. 1 Bureau whom Polu joked about before were gathered together again. This time, they will fight for an unprecedented goal!
There is another long brick kiln next to the experimental furnace. This time, it will be operated for the production of refractory bricks. After the first brick-burning experiment, when the temperature of the furnace dropped to the appropriate level, the workers opened the furnace and finally could go in.
During the inspection, Polu took the lead and got into the furnace. He looked at the refractory bricks in the furnace, used a small hammer to knock on the bricks whose surfaces had been sintered into glass-like shapes and connected together, and said to Geora and Smith next to him.
: "The melting is a bit severe at this high temperature. It seems that the furnace must be water-cooled, otherwise the clay brick furnace wall alone will burn through sooner or later, which will be a big trouble. Okay, the simulation experiment is over, let's arrange production.
."
Soon, the workers who had been busy for several days moved out large clay bricks pressed with molds. These bricks were 30 centimeters thick and turned into a slight arc. After calculation, these arcs allowed them to be perfectly formed in the furnace.
Arc shape. Fortunately, the basic knowledge of solid geometry that Boru still remembers is still enough.
Bolu turned around and left here, and came to the bending place of the iron plate furnace shell. Without the help of people and computers, it is unrealistic to prepare every piece of the furnace shell on site and install it directly into a perfect conical furnace body.
Things, being able to calculate the arc of the furnace shell is already the limit of Polu's current mathematical level. To build such a blast furnace in this era of technological level, it feels like the place of manufacture is not a batch of industrial products, but a statue, a work of art.
It is a monument that requires many people to work together to complete it.
Cranes also don't exist. The technology tree is not lit at all, so such a tall building cannot be hoisted at all. There are no such long steel beams to make one on site, so we have to use clumsy methods to pile up earth slopes. Iron that is cut into segments
The furnace shell was pulled to the construction site by a tractor pulling a pallet truck. The workers used a winch to pull the small pallet truck, and by the way, they pulled the furnace shell up the slope along the soil slope, and then installed it on the inner mold made of wooden boards. Waiting for a while
After the steel ring shells were installed, Polu personally cut the steel shells to fit, and then welded them together, and also welded a circle of up and down cross-stretching ribs. It took 9 days just to install the furnace shell.
.During this period, many people who were not on duty came to see this spectacle, which looked like a hill from the ground.
After Polu repeatedly checked that the structure of this 30-meter-high steel tube had been welded, he scraped off the surrounding soil, revealing the furnace body and the foundation made of slag concrete. Soon, the supporting steel frames of the furnace body were staggered
It was installed. Because no one had much experience, just in case, the steel frame composed of short steel beams was densely packed and looked like a shaft of steel structure.
At this time, 20 days had passed leisurely, and the shell of the furnace had just been completed. The exhausted Polu had to admit that the construction period of the furnace was much longer than he expected!
