They used copper casting, but they tried all the iron smelted in Guangdong, and none of them could survive twenty shots.

This is still government-run, and the quality is much better than that of the private sector!

It seems that the iron smelted by Li Feibai's private iron-smelting workshop can guarantee that it will not be blown up, so it is a deceitful ghost!

Although after understanding that Li Feibai was a businessman, Wang Feng was no longer hostile to Li Feibai, he felt that he had to ensure the quality of the Franc machine, so he didn't let Guo Taibao believe Li Feibai's rhetoric and use iron to build the Franc machine. When a batch of defective products comes out, he will be unlucky in the end.

Wang Feng took a step forward and said, "How do you ensure that the iron-cast barrel does not explode!" ”

Li Feibai said: "Why does the iron-cast broken pipe blow up!" ”

Wang Feng said: "There are too many impurities in the iron, so it will be blown up!" ”

Li Feibai said: "That is to say, because the quality of the iron smelted is not good, then improve the quality and remove the impurities!" ”

Wang Feng also put a lot of effort into making a Francophone machine, if he can use cheap iron to cast, why use precious copper to cast, doesn't he know that using iron to cast saves money?

But he squatted in the iron smelting station for a month, staring at the craftsmen smelting iron, and finally came to the conclusion that with the current level of smelting, it is more difficult to remove the impurities in the iron than to ascend to the sky.

In order to reduce the impurities in the iron and obtain steel that can be used to cast the barrel, it is necessary to use the tempering method. It is also to use the method of thousands of tempers to remove impurities in the iron, but the cost is higher than that of direct copper casting.

But now he didn't want to talk to Li Feibai about this, so he went straight to the point and said: "The barrel is all welded, and it is impossible to cast it at one time, so it can only be cast in half first, and then welded." After our trial production, we found that the welded copper cannon tube is not easy to explode, and the welded iron cannon tube is very easy to explode, how do you solve this problem! ”

Li Feibai said: "It's easy to do! Directly cast into a solid one, and then hollowed out to make a barrel, there is no gap without welding, and it is not easy to blow up! ”

Wang Feng was stunned. Using a solid iron pipe to hollow out the inside to make a cannon barrel, why did he not think of this method? In this way, even if there are too many impurities in the iron, it is not easy to blow up. But what's the use of thinking of it? To hollow out a solid iron pipe is not something that can be done by manpower?

He shook his head and said, "Gongzi Li, this is standing and talking without backache......" Before he finished speaking, he only heard Li Feibai say: "Lord Wang doesn't believe it?" ”

Wang Hong shook his head firmly, and said, "Unless you use divine power, it is impossible!" ”

Li Feibai said: "I can do it without the help of divine power!" "Anyway, let the soldiers bring the firecrackers in their hands.

After the soldier got Guo Xun's consent, he offered the firecracker.

Li Feibai took the firecracker, threw it directly to Wang Hong, and said, "Lord Wang, look at it, this gun can have traces of welding!" ”

As soon as Wang Honggong started, he immediately felt that the iron used in the pipe was extraordinary, and the pipe body was unusually smooth, and there seemed to be no impurities at all.

He raised his gun and took a closer look at the lamp. It would be an exaggeration to say that there is no impurity in the pipe, but the impurities are so small that they are negligible.

He turned the gun again, looked carefully little by little, and looked at it three times, but still did not see any traces of welding on the gun.

He Ru and the other three have stretched their necks like ducks' necks, looking forward to looking forward to seeing the fire guns.

Wang Feng couldn't chill the hearts of his subordinates, handed over the gun to the three of them to watch, and asked eagerly: "Is the gun really made by you?" ”

Li Feibai smiled: "I didn't make it, could it be that Wang Da made it!" ”

Wang Feng said: "How iron is refined to have so few impurities, it is not too much to describe it as steel. Also, how exactly do you make the gun tube not show a trace of welding, is it really a pipe hole drilled under the foundation of a solid gun pipe, as you said? What kind of tools can be used to drill the pipe hole? ”

Li Feibai said: "Lord Wang asked so many questions in one go, I really don't know how to answer." But after thinking about it, its practical words can be answered. This is a trade secret and is not advised! ”

Wang Feng knew that Li Feibai was a businessman, and it was reasonable for Li Feibai to answer like this, he thought about it and said, "You can also use this method to make a cannon barrel for the Franc machine?" ”

Li Feibai said: "Such a small gun tube can be made, how can such a big gun barrel not be made!" ”

Wang Hong smiled. Li Feibai is right, things like iron pipes are naturally smaller and more difficult to make, and bigger the easier to build. He said, "How much silver are you going to sell for each Franc gun barrel?" ”

Li Feibai said: "It must be much cheaper than the copper pipe you use, and it will not exceed the price of one percent!" ”

A glint flashed in Wang Hong's eyes. If the price of steel pipes is less than 10% of the price of copper pipes, that would be great. The whole Franc machine is more expensive than the gun barrel, and the lower the price of the gun barrel, the more Franc machines can be built. The more furlong machines you build, the more likely you are to use them in battle with the enemy.

The more battles he wins with the Franco, the greater his merit and the higher the rank he can rise.

It's a virtuous cycle!

He nodded, and was about to agree, but heard Li Feibai say: "However, I have one condition!" ”

Wang Hong's heart thumped. He said, "Well, there is no such good thing in the world." The most difficult thing to build in the whole Franc machine is the cannon barrel, and if the cannon barrel is made, it is equivalent to building the Franc machine. How could Li Feibai not see the mystery of this, it was related to his glory and wealth, and the condition mentioned by Li Feibai must be harsh!

Said: "What conditions! ”

Li Feibai said: "I want to cooperate with Lord Wang to create an artillery that is ten or even a hundred times stronger than the Francophone." ”

Is there an artillery in the world that is ten or a hundred times stronger than the Franc machine?

Wang Feng didn't believe it. After he knew how to build a Fran machine, he also consulted many craftsmen, and studied it day by day with He Ru, an imitation genius, and finally came to the conclusion that the Fran machine they built was the best Fran machine in the whole world.

Even the Franc machine made by the Franc machine can't be compared with the Franc machine they made, and there is no artillery in the world that is stronger than the Franc machine, and it is ten times stronger than the Franc machine when it is strong.

He looked at Li Feibai and smiled. This guy is good at everything, but he lacks a door, and he dares to boast about such a Haikou!

Said: "Li Gongzi thinks that the Franc machine is not perfect enough, and there is still room for improvement!" ”

Li Feibai said: "The Francophone can't be described as perfect, because it's too shoddy, and in my eyes, it's not qualified!" ”

Wang Hong's heart ached. Francois was made in his hands, like his son, but now his son is said to be worthless, so how can he not be angry.

However, Li Feibai's relationship with Guo Xun is really good, which makes me a little jealous. Forcibly suppressed the dissatisfaction in his heart, and said: "Ask Li Gongzi for advice, what do you think there are still improvements in the Francophone?" ”

Li Feibai walked towards the largest Franc machine and said: "The range of the Franc machine is too short, the largest is only one hundred and fifty paces, such a range, when encountering a cavalry charge, it can only shoot one shot, and it can't play a strong deterrent effect!" ”

Does the Franc have a short range? Wang Feng also felt close, but there was no way to do it, because in order to facilitate the placement of the sub-cannon, the Franc machine opened a large hole in the back and upper part of the mother cannon. After putting in the sub-cannon, although there is something behind it to cover the big hole, it is finally ventilated everywhere, and after the gunpowder explodes, a lot of air waves are emitted from all directions, and it is powerless to push the projectile to shoot farther.

For the time being, there is no way to solve this drawback, and he does not believe that Li Feibai has a solution. smiled: "Li Gongzi can increase the range of the Franc machine?" ”
