Chapter 233

Although the intention contract signed by ziqiongcheng and Ma Ning is only a * * * *.

But it can be said to be the first strategic trade contract signed by the rabbits in Da Mo world so far.

Previously, whether it was ma Yinglong hemorrhoids ointment, animal control law or happy stick, it could only be regarded as a brother in front of this contract.

Even if the movement of happiness bar involves the long-term transaction of tens of thousands of spirit stones, it is not irreplaceable in nature.

Not to mention the mining of the spirit stone vein, a pile of spirit stones can be sold only from the remains of monsters in the rabbits' freezer - without discussing how much research results will be lost, at least it is really short of money. These things can exchange a lot of spirit stones.

Generally speaking, rabbits walk more slowly without the happy stick trading, but they won't be unable to live.

Executives with a monthly income of 100000 will become caterers with a monthly income of 7000. There must be a gap in the quality of life, but Gou may not have a chance to turn over in a few years. Just grind it slowly.

The floating array is different.

It is a resource that rabbits can't replace at present. Without it, rabbits really don't know where to find a finished product using anti gravity technology.

Yes, of course.

The handover of the most important things also needs a cycle, so you might as well focus on other places first.

.........

Four days after the contract was signed, yangbei city.

At this time, it has been eight days since the rabbits broke the city, and it is less than 48 hours from the first seven of Mo's family.

In the past four days.

Just as the firewood camp is constantly preparing for the moon plan, many projects in yangbei city have not stopped for even a quarter of an hour.

For example, at this moment, the battle department outside yangbei city.

After the capture of yangbei City, it was temporarily set as the handover center of all matters of yangbei city.

"Brigadier long, let's keep in touch at any time. Walk slowly."

In the command tent, Lin Ziming had just sent away long Xinghe, who came to hand over the public security problems in the city, when he saw Lei Wenjun running from a distance in a hurry:

"Colonel Lin, the results of iron ore exploration have come out!"

Hearing this, Lin zimington raised his eyebrows and hurriedly took him into the temporary command tent. He pulled a chair and motioned him to sit down:

"Director Lei, why don't you sit down and take a breath first? How about the scale of the iron ore?"

Lei Wenjun sat on the chair and took a short breath. His rough palm wiped the lip corners of his beard and said with great excitement:

"Lin ceiling, good news, it's a medium-sized rich mine, much better than we originally expected!"

Lin Ziming was overjoyed when he heard the speech. He took the initiative to hand over a bottle of Nongfu mountain spring and asked:

"Director Lei, can you introduce me to this... Is medium-sized rich ore a concept?"

Lei Wenjun took the mineral water bottle and gulped. The clear mineral water bottle went into his stomach, which immediately made him happy.

Then he closed the bottle, thought about it and said:

"Colonel Lin, medium-sized rich mines... This is actually a combination."

Then he held both hands into fists and gently touched them with the little thumb joint of the right fist and the thumb of the left fist, indicating that these are two separate concepts:

"In terms of iron ore grade grading, we call iron ore containing more than 50% iron as rich ore, 35% - 50% as low-grade ore, 25% - 35% as lean ore and less than 25% as ultra lean ore.

About 97% of our local iron ore reserves are lower than 35%, belonging to low-grade or even ultra lean ore.

The average grade of iron is about 55%, and the reserves of rich iron ore that can be directly put into the furnace only account for 2.7% of our total reserves, so our iron ore has always been imported from kangaroo.

According to our exploration, the iron ore in yangbei city is of high quality, with an average taste of about 67%, which can be said to be the top iron ore resource.

For example, the average grade of the best Shilu iron ore in our country is only 51.2%, and the highest is 69%. "

Then Lei Wenjun paused. After confirming that Lin Ziming could understand his meaning, he continued:

"As for medium-sized iron ore, it refers to the comprehensive evaluation grade of exploitable reserves and annual exploitation of iron ore.

According to our survey, the total storage capacity of yangbeicheng iron mine is about 60 million tons. After the mining equipment is completely built, the annual mining capacity should be about 2 million tons. "

Lin Ziming nodded. He had known the concept of reserves during this period of time.

Although the reserve of 50 million tons seems to be a large number, it is not a large mine in the field of minerals - it can be seen from the concept of "medium" given by Lei Wenjun.

Because the density of ore is too high, ordinary ore the size of a football is more than ten kilograms.

At present, there are no less than 100 iron ores with reserves of more than 100 million tons in China, of which Benxi iron ore resource reserves in Liaoning Province are 3 billion tons, and the predicted prospect can reach more than 7 billion tons.

Regardless of the geographical distribution, if the figures are averaged alone, almost every province in China can have three hundred million ton iron mines.

Therefore, even if the iron ore grade of yangbei city is higher, it is actually a provincial iron ore scale.

After knowing the relevant data, Lin Ziming, the math slag, began to hum and hum to estimate the steel output. He said that he could make the math teacher die in peace:

"The annual output is 2 million tons, two hundred divided by three hundred and sixty-five... It's too troublesome to calculate according to four hundred days.

That is, more than 5000 tons a day.

According to the iron content of 67%, it can refine more than 3000 tons of iron every day. "

To his surprise, Lei Wenjun shook his head decisively:

"Colonel Lin, if you want to refine more refined iron, it is impossible to get 670kg finished products for a ton of 67% iron ore.

Because the ore after ironmaking will contain a lot of iron, which can not be completely refined. What's more, the 67% grade refers to the iron content of the ore on a dry basis, and the water content should be calculated separately.

How much iron can be produced in factory production depends on the most accurate yield. If it is conservatively estimated... Iron ore can produce 2800 tons of iron every day. "

Lin Ziming gave a sound, and then suddenly thought of something. He returned to his seat and called out a document.

The title of this document is "material consumption budget for the third phase of firewood camp (second refined Edition)".

Lin Ziming opened the document, pulled down the mouse to a column and murmured:

"The average daily consumption of phase II of the life experimental base is planned to be 337 tons... The average daily consumption of the military base in the non ordnance production stage is planned to be 164 tons... The daily consumption of chixian city is planned to be 709 tons... Including the coal mine and yangbei city... It seems that it is barely enough?"

The steel consumption estimate of the headquarters is not a false document made at random, but a reasonable figure calculated by spending a lot of time and hair.

Taking the planned daily consumption of chixian city as an example, how is the figure of 709 tons per day calculated?

This has to mention a concept:

Per capita steel stock.

Per capita steel stock is a representative indicator of industrialization and urbanization in a country and region. It is a macro indicator that any country will track and study for a long time.

What does that mean.

To put it bluntly, it is the total amount of iron in all your property every year.

For example, the iron consumption of a car is 1 ton. The average square meter of a reinforced concrete house uses 60 kg of steel bars. If you have a car and a house, this index will go up.

Of course, the actual statistics will also add the equal share of state-owned public iron and steel equipment.

In terms of per capita iron and steel reserves, when Eagle reached the peak of total iron and steel reserves, the per capita iron and steel reserves began to stabilize when neon was about 10.5 tons. When China completed industrialization, the per capita iron and steel reserves reached 9.5 tons, bald countries... Cough, John cattle was 7.6 tons.

On the whole, to complete industrialization, a country needs to have a per capita iron and Steel Reserve of 8 ~ 10 tons.

After reaching this peak, the value of iron ore will not be high - because steel can be recycled and scrap steel is used in developed countries.

At present, our per capita steel stock is more than 8 tons, and it is expected that complete industrialization will be completed in 2027.

This is also the core reason why it is said that kangaroos can't jump for a few years - at present, their biggest constraint on us is iron ore. once our industrialization is completed, the combination fist will directly shout in the face.

So don't really think that the official media are threatening and weakening others in the void. We really have this ability. We just have to wait a few years.

Based on the savings development function derived from this base, the core finally set the daily steel consumption of chixian county at 709 tons.

After all, the infrastructure of chixian county can be said to start from scratch, and the daily consumption of steel required can not be a small number anyway.

If yangbeicheng iron mine can produce more than 5000 tons of iron ore per day.

Then, with the yield matching that rabbits have now fully optimized to the extreme, the refined steel is completely enough for the development of several regions at present, and even has a slight surplus.

Yangbeicheng iron mine is a standard open-pit mine with low mining difficulty - the Mo family has opened the working face in advance, and the rabbits just need to continue to work against the working face.

In addition, the military base already has the military assembly capacity. It is completely easy to free up some to assemble civil steel-making equipment, which is nothing more than two sets of hydraulic units.

Therefore, the goal of 5000 tons per day is not difficult to achieve, especially compared with the little brother of the coal mine.

If the progress of the coal mine is that of the author of yuegeng novel, the iron mine is that of the tentacle monster with a daily increase of 20000. I'll print out a million word novel for you every minute.

If the iron ore can achieve this daily output, it also means that the local side can free up some light door transportation capacity.

At that time, whether this part of transport capacity is used to transport other materials to the Da Mo world or the aura of the Da Mo world back, it is only a matter of material handover.

This is very, very good news, so Lin Ziming quickly reported it to the headquarters.

Not long after he reported the relevant matters, news also came from Mo's house:

The underground tunnel has been hit two meters away from the secret room. You can break into it at any time!
