Chapter 221: The Napoleonic Cannon and the Hongyi Cannon 1

In the idea of Xia Nan, the new county town should be divided into residential and commercial areas, with a reasonable layout, and necessary municipal facilities such as sewers and public toilets should be built, and the road surface should be poured with cement. Pen @ fun @ pavilion wWw. biqUgE怂 info81 He doesn't want the streets of Xincheng to be potholed, and when it rains, the road surface is seriously waterlogged, and there are people who defecate at the corners of the alleys.

Liu Quanying: "Yes, sir." Do I have to re-apply for the title deed and title deed of the newly built house? ā€

"It must be redone, and the house deed and title deed are stamped with the big seal of the county government." Xia Nan actually wants to overturn all the old deeds, but at present, the people must still believe in the deed and title deed filed by the government, so they will continue to use it for the time being, anyway, the actual control of the land is in their own hands, but it is used by borrowing the skin of the government.

After making important instructions on the planning of the new city, Xia Nan was about to go back to his home to see the newly built Zhuangzi, when there was a commotion behind him, and someone shouted: "Xia Nan, call him to see me!" ā€

Sima De and the others were extremely surprised, now in Lingao, there are still people who dare to call Xia Nan's name? Xia Nan reacted, slapped his forehead, and said with a wry smile: "Oops, I forgot that there is this adult on the ship......"

This time he returned to Lingao from Dengzhou, and also brought back the former governor of Denglai, Sun Yuanhua, and a group of Portuguese. The Portuguese said that as long as they could escape Dengzhou and escape the butcher's knife of the rebels, they could go anywhere, but Sun Yuanhua always thought that he was returning to the capital. It's just that because his old man rarely takes a sea boat, as soon as he gets on the ship, he vomits in the dark, and he has no time to care about which direction the ship goes, and the "Yangming" sails too fast, and when he arrives at Bofu Port, he still thinks that it is in the area of Aoshanwei or Lingshanwei in Shandong Province.

After Xia Nan and the others came ashore, they were so excited that they forgot about Sun Yuanhua for a while. He followed the Portuguese and got off the boat in confusion, looking at the strange buildings on the dock, not knowing where he was, looking for people everywhere to ask, only to know that he had actually been taken to Qiongzhou Mansion, and he was furious for a while, wanting to ask Xia Nan to understand.

After making a fuss, seeing Xia Nan, Sun Yuanhua's face was ugly: "As early as when Dengzhou went out of the city, I saw that you are not simple, and the nursing home under your command is even better than the officers and soldiers. I was deceived so hard before, and I was really scheming. You...... Tell me quickly, what are you doing by bringing the old man to this place far away from the Emperor Gao? ā€

Xia Nan smiled and said, "Don't be angry, listen to me explain slowly." In fact, I didn't contact Li Jiucheng and the others at all, but I knew that even if Li Jiucheng agreed to let you go back to the capital, you would only have a dead end. I can't bear to see you kill yourself, so I tricked you into coming here......"

"Nonsense! As soon as the old man escapes like this, he will be convicted of colluding with the rebels, and my name will be ruined in your hands......"

Xia Nan waited for him to split his head and cover his face and accuse him, and then said in a hurry: "My lord, if you really want to keep your name and go back to the capital to die, you can arrange a boat to see you off." However, since you have come to Lingao, you might as well visit the factory where I cast guns, and it is not in vain! ā€

"......" Sun Yuanhua was interrupted, and his attention was attracted, "...... You mean, the kind of Hongyi cannon that introduced me in the first place? ā€

"Exactly." Xia Nan pulled Lin Weiye and introduced, "This is the strange man I told you, and it is his credit for making iron and casting cannons." ā€

Before the trip to Dengzhou, the steel plant established by Lin Weiye already had the advanced iron-making technology of this era, but it was stuck in the fuel link and could not get gray iron, so it owed coking coal. As soon as the qualified bituminous coal was brought back, Lin Weiye immediately made coking coal, replacing charcoal with coking coal. After reaching enough furnace temperature, after several experiments and smelting several furnaces of iron, he finally got the gray iron he dreamed of. Before he set off to go to Shandong with Yang Youji, the arsenal had already begun to cast larger caliber cannons out of gray iron, and the 12-pounder Napoleon cannon had already been made into prototypes, just waiting for the summer to be mass-produced.

Lin Weiye does not know much about history, but he also knows Sun Yuanhua and has great respect for this historical celebrity who attaches great importance to Western technology. When he was on the boat, in order to keep it secret, he didn't have any contact with Sun Yuanhua, and at this time, he handed over the bottom line, so he stepped forward to salute: "I've seen Lord Sun." ā€

Sun Yuanhua heard that the strange man who used coal to make iron to cast cannons was in front of him, and he didn't care about any reputation for a while, so he grabbed Lin Weiye's hand and asked excitedly: "I heard that you can use simmered coal to make hard but not brittle pig iron, and the cannon cast is extremely strong and will not explode?" ā€

"Yes. This kind of pig iron is called gray iron because of its dark gray cross-section. This kind of pig iron is easy to cut, and the cannon made is smooth and flat, not easy to leak, much more powerful, and can be hit farther. What's more, this kind of pig iron cannon is not as brittle as ordinary pig iron, and it will not explode if it hits dozens ......or hundreds of cannons," Lin Weiye tried his best to introduce in easy-to-understand words.

"I see, it's really a miracle!" Sun Yuanhua was amazed.

He has spent his life studying Western artillery technology, and although he does not know the terms "air tightness" and "clearance", he knows the huge gap between a finely polished and cut barrel and a shoddy barrel - the tighter the cannon and the barrel, the greater the force of the gunpowder to push the cannon, and the cannon can hit far; On the other hand, if the gap between the cannon and the barrel is too large, most of the thrust generated by the combustion of gunpowder will be wasted, and it will naturally not be able to hit far. This alone is already amazing, coupled with the advantage of not being easy to explode, such a cannon is enough to be called an "artifact".

Since this stubble was mentioned, in order to appease Sun Yuanhua, Xia Nan accompanied him to visit the arsenal, and Wu Duowang and others also followed.

The arsenal has long since demolished the original simple wooden houses and replaced them with bamboo-reinforced concrete buildings. The workshop of the cannon casting is unusually spacious, which reminds Xia Nan of the factory workshop in the seventies and eighties of the old time and space.

Lin Weiye was not allowed to act as a commentator, he pointed to a gun barrel that was being polished and said: "This is a 12-pounder Napoleon gun, the same caliber as the 12-pounder mountain howitzer, but the gun body is more than twice as long, 1.6 meters long, and much heavier, about 55o kilograms, and the effective range can reach about 15oo meters......"

Sun Yuanhua was confused, and he asked Xia Nan in a low voice: "What is this kilogram and rice?" ā€

Xia Nan coughed and reminded: "Lao Lin, don't use metric units, follow the customs." ā€

Lin Weiye came to his senses and changed his words: "This cannon commander...... 5 feet, ...... weight It's about 1,100 catties, and it can be played three miles away......" He is not very clear about the conversion ratio between the length and mass of the Ming Dynasty and the modern metric system, so he can only estimate an approximate value. (To be continued.) )
