Chapter 363: Palm Thunder

Shu banknotes are different from copper coins, the printing cost is very low, and most of the Xixia people dare not use it with their perception of currency.

If they dare to use it, Su You will dare to engage in a local inflation and an economic war that benefits but does not cost money.

Shaking his head to shake off this beautiful thought, Su You said: "It's in vain, don't talk about this, come, the kindness of the hometown people, Su You will always remember it, drink this cup together, even if it is to catch the wind!" ”

That night, Su You and Li Laozhuan studied the map and prepared for the next day's trip.

The next day, a team of several hundred people separated, and Shi Lian led the engineering team to inspect the tributaries of the Jing River and prepare for the construction of a hydraulic workshop, which will be used in the processing of agricultural products, wool spinning, and maintenance of military weapons in the future.

The mice began to fight against the documents and archives of Weizhou over the years, checking prices, counting the warehouses, and evaluating the basic data for the financial budget.

Cheng San led the people to clean up the site, put the banknotes into the warehouse, unpacked and took out the brass engraving, mixed the ink, and prepared for the Shu banknote workshop.

Shi Da didn't say anything, but on the way here, he had already discovered several high-grade lime mines for cement.

In addition, there are quartzite, dolomite, granite.

While searching for several dilapidated pottery kilns, Shi Da also found kaolin, a very high-grade kaolin, from craftsmen.

Coupled with the news from Shangzhou Shitong Kuaima, the iron ore there is different from Dali and Erlin, it is a kind of iron ore that does not contain sulfur, Shi Tong swore that he had discovered the secret of the Qingfeng Sword of Western Xia and could not wait to prepare for the experiment.

The iron ore that does not contain sulfur in this area is undoubtedly silicalite.

It's so useful that it can dramatically change the properties of steel.

The final stage of steelmaking must undergo deoxidation reaction, and the chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer in steelmaking, and can be used for precipitation and diffusion deoxidation in the later stage to improve the steel grade.

Depending on the ratio, it can significantly improve the strength, hardness and elasticity of steel, and is used in the production of frame steel, tool steel and spring steel.

The finely ground ferrosilicon powder can be used as a suspended phase in mineral processing. Use grease and other materials to make a beneficiation slurry, so that the coarse ore floats up, and the concentrate sinks to the bottom of the separator pool.

Of course, the most practical thing is to modify the performance of cast iron.

Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in the iron, promote the precipitation and spheroidization of graphite, and thus obtain ductile iron.

This cast iron can achieve or this close to the mechanical properties of steel.

The reason why Meishan arrows have always been conical is because the processing cost of other shapes is higher.

For Su You, a fine and pure science and engineering iron rooster who must be compared, the cost of an extra penny is unbearable.

But with ductile iron, Su You didn't mind changing the shape of the arrowhead and casting it into a wider, sharper, and barbed one.

Su You is very pleased that after ten years of development of metallurgical technology, the crane shin crossbow is no longer an unattainable dream.

With this iron ore, Su You's confidence in fighting against Western Xia has increased by one percent, and this iron ore is even more precious than ten Erlin iron mines.

There is only one reason - the cost of transportation.

It was right in the rear of the battle line.

But there is no need to tell Shi Tong first, this apprentice is a little floating now, and after the ferrosilicon comes out, I will teach him to be a man.

Before leaving, there is one more thing to be busy with - assembling the set of parts handmade by Shi Fu and brought by Shi Gong.

The core component is a runner with a pinion at one end and a hole in the center, which is connected in series to the base by a steel shaft. So that the runner can turn.

The front end of the steel shaft can be pulled out of a distance so that it can be thrown out of the hole at the rear of the base along with the runner and thrown out to the left.

The trigger on the base, hidden in the steel structure above the handle, moves the hammer backwards and pushes the wheel one square at the same time.

There are six holes in the runner, and with each turn of the grid, there is a hole facing the steel pipe in front of it.

That's right, this is a killer weapon composed of a bottom handle, frame, barrel, revolver, slewing, braking, locking, hammer, and trigger - revolver.

The frame is similar to the receiver on a normal gun, with many slots cut out on it in order to unite all the mechanisms and parts, such as the barrel, grip, etc.;

The trigger is double-acting. You can either use your hand to press the hammer to make it ready to fire, or you can directly pull the trigger to shoot automatically to be ready for fire.

The pistol is made of manganese steel, and the barrel has rifling, just one barrel, but it is the highest achievement of Meishan metalworking today.

The long barrel was already there, but the work of the boring tube was almost stalled due to the defect in the hardness of the cutter head, let alone cutting the rifling in it.

However, the problem of short pipe is not big, Shi Fu directly used the soft forged iron manganese pipe to boring out the inner hole, and then used the high manganese hard steel cutter head to boring out the rifling at any cost, and finally used the carburizing process to turn the iron pipe into a steel pipe, and then fine grinding treatment, which solved this problem.

Except for the round parts, the rest are all handmade, front and back, it took Shi Fu half a year of effort.

Of course, there are a lot of tools and measuring instruments involved in the design, and Shi Fu said in a letter sent with the parts that he is now sure that the time will be limited to less than a month and a half.

However, the cost is too high, the cost of time is too great, and this thing will be the stuff of the nobles for another ten or twenty years.

Shi Fu is now shaking very much, and the official edicts dare to ignore them, refuse to obey the edicts, and now he is obsessed with metal processing technology.

The main work is still a cold weapon, there is a ladder pattern steel sword into the Liao State, the Queen Mother of the Liao State immediately into the bag, the worship of the official in the blink of an eye to promote three levels.

Therefore, this revolver is inevitably equipped with an ivory handle, carved, and the metal part is gilded and silver, which is extremely gorgeous.

The crosshairs are to shine on the door, it is a bas-relief Pixiu, and the hammer is a vermilion bird, which is both practical and decorative.

And that's not even counting the cost of ammunition.

If you have thunder mercury, you can make a primer.

Mercury can easily react chemically with copper caps, resulting in munitions malfunctioning or accidental injury.

However, the Song people are experts in playing with lacquer, wrapping a thin layer of wax paper for the use of thunder mercury to shoot medicine, and then sealing it into the lacquer and filling it with a copper cap, you can get a qualified primer.

The propellant Su oil used purified gunpowder, and ammonium nitrate, a powder prepared in the Kuizhou laboratory, was added.

The warhead is a steel-core copper-plated lead bullet, which consumes a lot of effort, and in Kuizhou for two years, Su You and Zhang Qi and Zhang Zao have drummed out dozens of bullets in total, and it is estimated that there are still a lot of dumb people in it.

It's useless to hold this thing by yourself, reaction and aiming are problems, but Shi Wei doesn't exist anymore, and she doesn't understand what it is, so she already likes it very much.

Take out the bullet and reload it, and with a dashing flick, Kata bang, uh...... Didn't close.

"Brother Xiaoyou is so stupid!" Shi Wei took it and shook it gently, and the nest rebounded with a soft sound: "This has to be skillful!" ”

Su You slipped and hid behind Shi Wei: "Be careful!" The muzzle of this thing is always downward, don't point it at anyone! ”

"Guns?" Shi Wei was inexplicable: "This is a gun?" How do you write this gun? ”

Su You stretched out his hand and carefully pushed a push button on the revolver, "This is the insurance, if you push it, you will not be afraid of accidental shooting, and you will open it when you want to use it...... Belch...... Or do you want to call it a gun? ”

Shi Wei couldn't put it down: "My brother's craftsmanship is getting more and more exquisite." What's the use of this? ”

Su Youthief smiled: "The next time you see your Heavenly Senior Brother, you can show him the palm thunder in a serious way, and you can't scare him to death!" ”
