Facts have proven that if a man's body is strong enough, he does not need to eat leeks to replenish his body.
However, for the country, leeks can still be cut as long as they can.
Of course, cutting too many leeks is also good for the country!
Why is the United States so powerful? The whole world is cutting leeks!
Facts have proved that the way to strengthen a country... is to cut off Philippine vegetables.
And when one's own skills are not good enough, it is even more necessary to cut leeks. Of course, some leeks are more stubborn, especially Western leeks, and may not be willing to be cut. But even so, you have to find a way to cut them.
For example, for a "leek" like Staum, even if you know that the guy is not a good leek, and he despises the Chinese people, you can't just kick him out. After all, there are too few Zhang Butchers in Nanhua.
Although butcher Zhang will not be able to eat pigs with hair on them, it will definitely affect Nanhua's technological development.
Sooner or later, we have to drive all those bastards away!
But before that, you have to squeeze out all his value! Only in this way can you be worthy of him.
However, not all Westerners are bastards. There are still a few good people. Smith, the chief engineer of the ammunition factory, is a good guy. He was sent by the manufacturer when Buffett ordered ammunition production equipment from the United States.
Engineers are responsible for guiding equipment installation and production as well as training workers. In this era, all factories will have similar on-site training services when receiving orders.
Among those ammunition production equipment, there are two sets of equipment for producing rimfire ammunition. This set of equipment includes nearly 60 machines such as roller compactors, extruders, and necking machines. However, these equipment are not suitable for the production of new center-fire ammunition.
bullet.
After learning about Zhu Xianhai's design, Smith immediately led his fellow engineers and technicians to modify one of the equipment and add a variety of equipment including the primer. It took nearly half a year for Smith and his team to
After hard work, Nanhua Arsenal finally produced the world's first batch of center-fire bullets.
"This is it!"
Zhu Xianhai looked a little excited when he looked at the bullet in the bottle with a narrowed diameter that was as thick as his thumb.
"With it, we can definitely conquer this grassland."
However, before he could get over his excitement, the new bullet was discontinued while it was still in trial production.
The reason why production was discontinued was not because of poor bullet performance.
In fact, this new type of .56-.45 caliber bullet blinded everyone with its excellent performance as soon as it was tested. The 14.22 mm thick and 32 mm long bottleneck cartridge case is enough to hold 2 grams of propellant. Although it is not as good as
It is equipped with a rifle, but it can allow an 11.43mm caliber bullet weighing 15 grams to reach a muzzle velocity of 320 meters, and the effective range against human targets is close to 500 meters, which is almost as good as the p1853 rifle.
With this kind of bullet, combined with the Spencer rifle, they will definitely be a weapon that sweeps the era!
The only problem is - brass is too hard.
Taking out a few rounds of new bullets with copper shells, Smith, the arsenal engineer, once again made a suggestion.
"In order to ensure smooth production, my suggestion is still the same as before. We should currently use copper cartridge cases. Otherwise, there is no other choice!"
As an engineer, Smith was undoubtedly very responsible and directly pointed out the root causes affecting production.
"Purple copper is too soft, and it is easy to overheat and jam. The cartridge case must be made of brass."
Whether he was dealing with the Gaucho cavalry or the expedition to Araucania, there were many cases where rifles jammed due to overheating of copper cartridges, so Zhu Xianhai insisted on using brass cartridges.
"But sir, when the extruder is extruding and extending the brass cartridge case, the steel mold is easily damaged and the accuracy becomes poor. Currently, a set of molds can only be used 200 to 300 times, while copper can be used thousands of times.
At a production rate of 10,000 rounds a day, molds need to be changed dozens of times a day."
Smith's explanation made Zhu Xianhai think for a while and then said.
"Since it's a mold problem, let's find a way to solve it."
As he spoke, Zhu Xianhai realized that the tool steel of this era seems to be ordinary carbon steel, and the mold of the extruder is also made of it. Its performance is slightly better than the steel bars used to build houses.
Yes, let’s find a way to solve the tool steel problem first!
Industry is a systems engineering.
Jump-forward development is simply unrealistic.
Not only do workers need training, but even the most humble tool steel not only limits the performance of machines, but also limits certain new inventions.
Fortunately, the crucibles for steelmaking were readily available - machine factories in these days often used graphite crucibles to make high-hardness carbon steel for the production of knives. This made it easier for Zhu Xianhai to trial-produce new tool steels.
What he chose to trial-produce was the most "original" high-speed steel. This kind of tool steel with high hardness, high wear resistance and high heat resistance was not invented by Americans until 1898. It is also called front steel, commonly known as white steel.
Steel. Its formula and manufacturing process are very simple.
It was when he was experimenting with high-speed steel that Zhu Xianhai realized that the reason why steel in this era was so expensive—as high as $167 per ton, and the cost of shipping each ton of steel to Nanhua would be a few more dollars—was because of the high-speed steel used.
The "crucible steelmaking method" not only takes a lot of time, but also consumes a lot of raw materials.
"If we build a steel factory and use open-hearth furnaces to make steel, wouldn't it be a huge profit?"
Zhu Xianhai's eyes couldn't help but light up.
"The converter steelmaking method should have been invented by now! However, it seems to have some technical problems..."
Although the converter steelmaking method invented by Bessemer has been put into use as early as 1855, it cannot use dephosphorization and desulfurization, so it can only use high-quality low-phosphorus iron as raw material, and the nitrogen in the air has a negative impact on the performance of molten steel.
It had a great impact, limiting the types and applications of converter steelmaking. This is why the open-hearth steelmaking method later became the mainstream steelmaking process.
"Siemens open-hearth furnaces... seem to be only used to melt glass. Well, there seems to be a glass factory in Nanhua... I just don't know if the glass factory uses Siemens open-hearth furnaces."
The beginning of industry is sometimes more difficult than imagined, and sometimes it is very simple, just like the Siemens open-hearth furnace - that is, a high-temperature flame furnace with a regenerator. It took nearly ten years to smelt glass before anyone used the Siemens open-hearth furnace.
Steelmaking.
In fact, technology development is always like this in many cases. When some new technologies are just invented, it will take a long time to be carried forward in another aspect. Before that, they were only partially applied in some aspects, and even
It is possible to be lost in history, only to be "salvaged" from old technology many years later.
