Chapter 1622: Gun Tower

Coke can obtain a mixture of hydrogen and carbon monoxide through water vapor, which is further converted into carbon dioxide and hydrogen under the continued action of water vapor.

If it is red-hot carbon, the oxygen in the air will turn into carbon monoxide and compounds of carbon dioxide and nitrogen.

After impurity removal and absorption, the substances needed to synthesize ammonia—nitrogen and hydrogen—are obtained.

It sounds easy, but the process is very, very difficult.

Because the purification process requires high pressure, the carbon dioxide is dissolved in water and absorbed and removed.

Do not allow oxygen to remain, otherwise it will explode when reacting with hydrogen.

Afterwards, the gas reaction requires two hundred atmospheric pressures, a temperature of six hundred degrees, and gas circulation.

This set of high-pressure vessels was not developed until the year before last during the development of diesel engines.

In addition, high-pressure power must be generated. The double-spiral gas compressor is a product of the research and development of cold storage.

After meeting the conditions, you still need a catalyst. This is quite simple. Su You brings the memory of his previous life and uses iron oxygen to catalyze it.

But there are still many problems. Even with a catalyst, the ammonia conversion rate is less than 20%. Therefore, high-pressure gas must be repeatedly circulated in the pipeline and continuously passed through the catalytic plate, which requires precision casting and welding processes.

Fortunately, thermite and arc welding can solve this problem.

There are also pressure vessels that use steel. Steel contains carbon and is easily decarburized by hydrogen under high temperatures and pressures.

Su You made a contribution to this problem - it's simple. When we didn't have good welding skills in the past, didn't we use copper sheets to make the inner liner of the train steam engine, and then wrap it with a steel shell to enhance the pressure resistance?

Then we can also stick a layer of pure iron on the inner wall of the high-pressure vessel. Iron has a catalytic effect. Wouldn't this solve the problem?

Zhang Tianshi tried this method, and the effect was very good. It also solved the problem of difficulty in processing - the steel shell is covered with iron sheet. The iron sheet is easy to process. The steel shell can be stamped in sections and fixed with rivets. The strength of 200 atmospheres is completely acceptable.

Guaranteed and greatly reduced equipment costs!

The idea of ​​synthesizing ammonia iron-oxygen catalyst and iron-clad steel allowed Su You to win the Outstanding Contribution Award in Chemistry two years ago in absentia.

The soul of science and engineering is that people are better at solving problems and reducing costs is God!

This is a witty saying that is now popular in various colleges of the Capital University.

With cheap ammonia, the later Hou's alkali production method and the real three-acid-two-alkali salt chemical industry were born.

This is the latest achievement in the development of science and technology in the Song Dynasty, and it is also the highest technological achievement in the Song Dynasty today. The technical content is higher than that of manufacturing guns.

Without the explosive progress of many new processes and inventions in the past few years, it would simply not be possible.

It took forty-three years to develop the ammonia synthesis process in the Song Dynasty. This was already a technology in the early 20th century. When people in the future evaluate the technological development during this period, I am afraid they can only use the word "awesome" to describe it.

One step further from here is chemical fertilizers and explosives.

Zhao Xu's fifteen million yuan can be handled by the production capacity of the Changlu Salt Chemical Base alone.

The Liao people are not afraid of this thing no matter how they look at it. This is a science and technology that is a whole generation ahead of the steel-making blast furnace.

The only critical factor is the geographical location. After Suyou inspected the base, he strictly ordered the governments of Dezhou, Jizhou, Shenzhou, Enzhou, and Cangzhou to mobilize civilian forces to dredge many rivers without encroachment. The depth must be sufficient to ensure the safety of this base.

Continuing forward, the ship passed Qingzhou, entered Wen'an Wa, also known as Baiyangdian, and then turned into the Juma River. After going upstream, it arrived at Bazhou.

By the Juma River, there is one male and one hegemon. Xiongzhou is Waqiao Pass and Bazhou is Yijin Pass.

The key and key battleground is where travelers come to look at Yanshan Mountain!

Later that year, Zhou Chai Rong was so angry that he sent his troops to the northern expedition to Khitan, and captured these two places without any bloodshed. He changed Waqiao Pass to Xiongzhou and Yijin Pass to its old name of Bazhou.

One hero and one hegemon, how much pride a generation of heroes has entrusted to them!

It's a pity that the ambition was not fulfilled. Chai Rong passed away in June of that year, and there was no successor after that.

There are two armies stationed in Bazhou: Sun Neng, the Zhenning army, and Cao Nan, the enemy's army.

Sun Neng is basically half a child of the Su family, and Cao Nan is also an old friend.

In order to seize the city, Su You secretly arranged for him to lurk in the Hoi An City Shipping Office through sea ships. He prepared more ammunition but showed that the enemy was weak, and deliberately lured He Li to send his army across the river to attack, so that the Song Dynasty could obtain the "self-defense counterattack"

"political correctness.

Originally, the battle would be won if they held firm, but Cao Nan cleverly designed a trap and deliberately missed a bamboo forest when carrying out the sniper attack, making the Heli army who was under attack think that it was a safe zone.

As a result, the defeated front army used it as a refuge, and the later arriving Chinese army used it as an advance base. In the end, it was bombarded by Cao Nan.

That battle was the first independent battle of the New Army. Five hundred men defeated almost all the 20,000 occupying troops. Cao Anmin became famous all over the world.

It was also after that battle that the Song Dynasty Navy formally established the Marine Corps.

From then on, the Marine Corps' style was established, which is to always face the enemy on the water and always defeat the most impossible enemy in the most desperate situation.

The small steamer that Su You rode made Cao Nan envious: "Situ, when will we be equipped with this thing? Give me five of these things, go along the Sanggan River, and we will go all the way south of the Great Wall."

I can get them all for you."

Su You rolled his eyes at him: "Well, why don't you go in along the Luanhe River? Then even the north of the Great Wall will be yours!"

This is not a complete joke. The Sanggan River Basin includes the entire southern area of ​​the Yanshan watershed. Now, sailing can reach Fengsheng Prefecture, Guihua Prefecture, and the Zhuolu area.

The Luanhe River can reach Bei'an Prefecture, which is above Chengde.

The Song Dynasty Navy was the only one in the world and had already gained absolute strategic advantage over the Liao Dynasty.

This is also Su You's consistent style.

You hit yours, I'll hit mine.

If you dare to come, I dare to bury you.

Before the Beiyang Navy was established, the Song army could only build a 600-mile water park to the east of Xiongzhou and Bazhou to prevent the Liao people from breaking through from the east of Xiongzhou and Bazhou to the south.

Then he deployed heavy troops in the two dominant states and garrisoned the two passes.

Even so, because the terrain is low and flat, it is still difficult to defend. The real strategic role is to attract the Liao people's military strength or threaten the Liao people's retreat after they advance.

Because it used to be saline-alkali land, there was almost no human habitation within a two-week radius of hundreds of miles, and all supplies were transported from the rear. The service work along the way to Hebei was extremely heavy.

After the Yellow River changed its course to the north, it took over the boundary river channel downstream of the two states and entered the sea. After being regulated, it formed a natural chasm to the east of the two states.

Moreover, the loess and flowing water brought by the Yellow River washed away the saline-alkali land and deposited it in the 600-mile water bank, which actually turned the water bank into fertile farmland.

Nowadays, many immigrants have come to this area. In addition, there are now many cattle and horses in the army. They have recruited merchants and villages, and they can actually achieve self-sufficiency in food.

The situation against the Liao Dynasty has been greatly improved. To the east of Baozhou, there are river defenses as support, while to the west of Baozhou, they basically have to go south to attack Zhending Prefecture through the Feihu Road, which is the gap between Taihang Mountain and Yanshan Mountain.

Otherwise, we have to go hundreds of miles further west, bypass Mount Wutai, and go south from Yanmen to attack Taiyuan Prefecture.

No matter which mountain pass, a new army is enough to cope with it.

However, Cao Nan's words gave Su You a wake-up call. Although the Song Dynasty was no longer afraid of the Liao Kingdom strategically, tactically there were still opportunities to steal chickens, such as during winter freezes, so they had to be on guard against it.

.

Thinking of this, Su You remembered something in later generations that once deeply detested the Chinese people: "Do you know that there is a thing called a blockhouse? It is a three-story nine-meter cylindrical building made of masonry, cement and soil, with different heights on all sides.

There are more than a dozen shooting holes and a dozen observation posts, and mortars can be mounted on the roof. Enough food and ammunition are stored in the building. A dozen people can live in one gun building, and trenches and barbed wire can be designed around the perimeter."

"In a plain area, a building like this can allow a dozen sergeants to completely control a radius of six to seven hundred meters, and it is not isolated. The gun towers can also echo each other to form a cross-firing fire network."

"With twenty of these small artillery towers and four to five hundred sergeants, it's easy to control over a hundred kilometers."

After finishing speaking, he took out his schoolbag and took a pen to draw a rough shape and interior diagram, and then drew a dot distribution diagram: "Divide it into two rows like this, ten in each row, staggered by 500 meters, so that each blockhouse is

It can form a triangle attack zone with the other two, and it will be extremely difficult to pass through."

Sun Neng took the pen and said: "This thing looks like a bastion of a city wall standing out independently. If it relies on the county seat... like this, teacher, look at it!"

Cao Nan took the notebook and pen and started drawing on it: "Relying on the mountain, build a few on both sides of the valley passage, um... and then connect them through trenches..."
