Chapter 363: Thunder in the Palm

Shu banknotes are different from copper coins. The printing cost is very low. Based on the Western Xia people's understanding of currency, most people would not dare to use them.

If they dare to use it, Suzhou dares to launch a localized inflation and engage in an economic war that benefits them at no cost.

Shaking his head to get rid of such beautiful thoughts, Su You said: "It's a waste of time. Let's not talk about this. Come on, Su You will always remember the kindness of the people in his hometown. Drinking this cup together will be regarded as a blessing!"

That night, Su You and Li Laoshuan studied the map and prepared what they needed for the next day's trip.

The next day, a team of several hundred people separated. The Shidai engineering team inspected the tributaries of the Jing River and prepared for the construction of hydraulic workshops, which will be used in future agricultural product processing, wool processing, and military maintenance.

The mice began to work with Weizhou's historical documents and archives to unify prices and inventory warehouses to provide basic data for fiscal budget evaluation.

Cheng San led the people to clean up the place, put the banknotes into storage, unpacked the brass engraving plates, mixed ink, and prepared for the Shu banknote workshop.

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

There are also quartzite, dolomite, and granite.

While searching for several dilapidated pottery kilns, Shi Da also discovered kaolin clay from craftsmen, which is extremely high-grade kaolin clay.

Coupled with the news from Shitong Kuaima in Shangzhou, the iron ore there was different from Dali and Erlin. It was a sulfur-free iron ore. Shitong swore that he had discovered the secret of the Xixia Qingfeng Sword.

Can't wait to get ready to test it.

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

This thing is so useful, it can significantly change the properties of steel.

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

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

The finely ground ferrosilicon powder can be used as a suspended phase in ore dressing. Use grease, etc. to make a dressing slurry to float the coarse ore, and the concentrate sinks to the bottom of the dressing pool.

Of course, the most practical thing is to improve the properties of cast iron.

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

This kind of cast iron can achieve or approach the mechanical properties of steel.

The reason why Meishan arrowheads are always conical is because the processing cost of other shapes is higher.

For Su You, a science and engineering rooster who is very sophisticated and always pays for every penny he spends, even an extra penny of cost is intolerable.

However, if he had ductile iron, Su You wouldn't mind changing the shape of the arrowhead and casting it into a wider, thinner, sharper and barbed one.

Su You was very pleased. After ten years of development in metallurgical technology, the crane-shank crossbow was no longer an unattainable dream.

With this iron mine, Suyou is 10% more confident in fighting Xixia. This iron mine is even more precious than the ten Erlin iron mines.

There is only one reason for shipping cost.

It's right behind the battle lines.

However, there is no need to tell Shi Tong this first. This apprentice is a little confused now. We can teach him how to behave after ferrosilicon is produced.

Before departure, there is one more thing to do: assemble the set of parts handmade by Shi Fu and brought by Shi.

The core component is a runner. There is a small gear at one end of the runner and a hole in the center. It is connected in series to the base through a steel shaft so that the runner can rotate.

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

There is a trigger on the base, which is hidden in the steel structure above the handle. Each time the trigger is pulled, the hammer will move backwards and the wheel will rotate one step at the same time.

There are six holes on the runner. Every time it rotates, there will be a hole facing the steel pipe in front.

That's right, this is a killer revolver consisting of a frame, frame, barrel, wheel, rotation, brake, lock, hammer, and trigger.

The frame is similar to the receiver on a general gun, with many slots on it to combine all the mechanisms and parts, such as barrels, grips, etc.;

The trigger is a double-action type. You can press the hammer with your hand to cock it, or you can directly pull the trigger to fire automatically.

The pistol is made of manganese steel, and the barrel is rifled. The short barrel is the highest achievement of Meishan metal processing today.

The long barrel is already available, but the work of boring the barrel has almost come to a standstill due to the defective hardness of the cutter head, let alone cutting rifling in it.

However, the short pipe is not a big problem. Shi Fu directly bored out the inner hole with a soft forged manganese iron pipe, then used a high manganese hard steel cutter head to bore out the rifling at any cost, and finally used the carburizing process to turn the iron pipe into a steel pipe, and then

Precision grinding solved this problem.

Except for the round parts, the rest were all made by hand. It took Shi Fu half a year of work from front to back.

Of course, it involves the design of many processing tools and measuring instruments. Shi Fu said in the letter sent with the parts that he is now confident that the time will be controlled within one and a half months.

However, the cost is too high and the time cost is too high. This thing will only be a gadget for the nobles in ten or twenty years.

Shi Fu is shaking so much now that he dares to ignore official edicts and refuses to obey them. Now he is obsessed with metal processing technology.

The main work is still a cold weapon. A patterned steel rapier with a ladder pattern was introduced to the Liao Kingdom. The Queen Mother of the Liao Kingdom immediately took it into her pocket, and the respected officials were promoted to three levels in a blink of an eye.

Therefore, this revolver inevitably has an ivory handle, carvings, and metal parts gilded with silver, making it extremely gorgeous.

From the front sight to the rear sight, there is a bas-relief Pixiu, and the hammer is a Suzaku. It is both practical and decorative. How can this be justified?!

This does not include the cost of ammunition.

Once you have mercury fulminate, you can make a primer.

Mercury fulminant can easily react chemically with the copper cap, causing ammunition failure or accidental damage.

However, people in the Song Dynasty were experts at playing with lacquer. They could obtain a qualified primer by wrapping a thin layer of wax paper used to trigger thunder mercury, then sealing it in lacquer and filling it with a copper cap.

The propellant Suyou used purified gunpowder and added a powdered ammonium nitrate prepared in a Kuizhou laboratory.

The warheads were steel cored copper-plated lead bullets, which took a lot of effort. In the two years they were in Kuizhou, Su You and Zhang Qi and Zhang Zao tinkered with dozens of bullets, and there were probably a lot of dumb bullets among them.

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

He took out the bullet and loaded it, flicked it gracefully, and it clicked, uh... it didn't close.

"Brother Xiaoyou's hands are so clumsy!" Shi Wei took it and flicked it gently, and the sound of the spring nest came back to life: "You have to use skill to do this!"

Su You squeaked and hid behind Shi Wei: "Be careful! The muzzle of this thing is always pointed downward. Don't point it at anyone!"

"Gun?" Shi Wei was confused: "This is a gun? How do you write the word "gun"?"

Su You stretched out his hand and carefully pushed a push button on the revolver. "This is the safety. If you push it up, you won't be afraid of accidental shooting. When you want to use it, turn it on... uh... how about calling it a gun?"

Shi Wei couldn't put it down and read it: "Brother's skills are getting better and better. What's the use of this?"
