Wencheng found a zodiac auspicious day, and used the custom of the Han people to carry a large sedan chair and carry Molis ten miles north of Loufan, and into the mansion of Qinchuan, Heishan Fort, which was the former backyard of Mengjiazhuang.

The wedding was the same as when marrying Wen Suxin and Li Yueru. From Loufan Town to Heishan Fort, the wedding was full of lights and joy. The banquet was filled with all the streets in the fort. The banquet was not rich, but there were dumplings, white noodles, roasted lamb and a large pot of stewed meat.

Su Tai, Ezhe, Namuzhong, Orzhetu and the nobles of the Chahar tribe attended the wedding as their parents' homes, and gave them 500 sheep, 100 cattle and horses as dowry. Qin Chuan gave each of them a pile of gold, silver, cloth, tea, and salt as a dowry.

Qin Chuan betrothed Su Tai to Lao Huang, married the Mongolian queen and gave it to the Mongolian prince, and Lao Huang was so happy that his big yellow teeth were almost gone.

Namu Zhong promised to Luo Daniu to buy one free one, and Namu Zhong and Lee Anru had completely different styles, which made the guy taste a different taste.

The younger and beautiful Orzhetu originally wanted to promise the Bobcao, but the guy was so blushed that he refused to ask for it, so he promised it to Li Dingliang.

Lin Danhan's two younger sisters promised Luo Ba and Liu Youzhu respectively. In addition, Qin Chuan also asked Ordos Elinchen to marry the most beautiful daughter to Feng Yilong, and then picked a few young and beautiful women from the families of Ordos and Chahar, and married Ren Liang, Hu Dawei and Cao Bianjiao respectively.

Like Bobcao, Li Dingguo rejected Qin Chuan's kindness in the name of being young.

The civil servants under Qinchuan were not very interested in Mongolian women. These literary guys basically only like petite Han women. Song Zhiting, Wen Zheng and others got drunk at the banquet and talked about the beauty of Qinhuai. The old guy Wen Zheng also praised Qinhuai with an intoxicated look on his face to praise a new talented woman named Liu Yin and Rushi, also known as Hedong Jun. She can be said to be both talented and beautiful.

The speaker is unintentional and the listener is intentional. When Qin Chuan hears the words Liu Yin, he becomes interested immediately.

Isn’t that Liu Ru, the leader of the Eight Beauties of Qinhuai?

Qin Chuan has long admired the Eight Beauties of Qinhuai, and of course he admired that kind of admiration, especially Chen Yuanyuan, Liu Rushi, and Li Xiangjun. Just listening to the name can make men swallow their saliva.

Liu Rushi in history has made Qian Qianyi's shameless allusion, the water is too cold and itchy scalp is famous in history. It's a pity that a generation of talented women has been surrounded by cow dung.

In this life, Qin Chuan can no longer let history repeat itself. Chen Yuanyuan, Liu Ru, Li Xiangjun and others are all his.

As for Qian Qianyi, Wu Sangui and Hou Fangyu, they were beaten to death.

...

Early the morning of the next morning after the third marriage, Qin Chuan walked out in the snow and climbed up the city tower and the office room to continue to be busy with government affairs. After handling important government affairs, he entered the workshop again.

Now that the mountains are covered with heavy snow, several new factories under construction in the Heishan Industrial Zone have been shut down, but the workshops are still busy, and they are busy rushing to rush for samples of brake force hammers and many linkage devices.

Chen Zhan and Li Xuejing's focus is on mass production of bearings, and Qin Chuan has come the most during this period as well as the bearing workshop.

Whether it is the production of external combustion engines, power hammers, or various linkage devices, a large number of bearings are required.

The prerequisite for mass production of bearings is to design a forging lathe forging lathe forging to manufacture various workpieces.

Qin Chuan, Chen Zhan and Li Xuejing discussed for more than half a month, formulated the manufacturing process, and the various lathes on the assembly line were initially designed.

First, it is rough forging. The steel made from the converter enters the assembly line and is hot forged by a large power hammer to increase the structural density and performance of the steel, improves plasticity, and reduces deformation resistance. Then it is cut into the same size of the embryo material by cutting the cutting lathe, and then the embryo material is fine forged twice, and then the embryo material is forged and pressed into molds.

After the formed workpiece is roughly ground, it also requires a series of tempering processes such as carburizing, nitriding, quenching, tempering, annealing, etc. Finally, it is fine grinding and polishing to finally obtain the finished workpiece, and then the workpiece can be assembled to obtain the finished bearing.

In the entire process, a series of processes such as forging and pressing are all completed by the lathe. The integrated lathes in later generations are very difficult, so they can only be made separately, including rough forging, cutting, fine forging, forming and grinding, all of which are powered by an external combustion engine and operated manually. The regulating process needs to be operated through a carburizing furnace and tempering furnace.

Among these five lathes, rough forging and fine forging are not difficult. There are three types of hammers, one large, one middle and one small. The number of hammers depends on the power of the external combustion engine. Cutting is not difficult, because it is hot cutting and the iron plate is still burned red, so it can be achieved by forging and cutting with a tool. What is difficult is the two processes of forging and pressing forming and grinding.

First of all, forging and forming, the red embryo needs to be forged into the mold, which requires high quality requirements for the mold, because the mold is also affected by the impact of the forging hammer and must not produce any deformation and cause the workpiece to be scrapped.

The existing technology cannot produce alloy steel, and can only obtain steel that meets the requirements through quenching and quality.

To this end, Chen Zhan and Li Xuejing conducted countless tempering tests, ranging from carburizing, decarbonizing, nitriding time, quenching medium, tempering annealing temperature and time, etc., animal oil, vegetable oil and water, as quenching medium, have tried dozens of different temperatures, ranging from zero to two hundred degrees, and the complexity can be imagined.

Each test records various data in detail, and the quality of the steel obtained by the test test is finally obtained after half a month of busy work.

In addition, a large number of tests have also concluded that various steels with different properties can be used as workpiece materials for various mechanical materials, and even better quality spring steels have been obtained. The barrel and gun barrel regulating method have been improved, thereby obtaining better quality barrel and gun barrel.

Another problem with mass production of bearings is the grinding process, which makes Qin Chuan a headache.

Natural grinding stones are definitely not available. In the past, Li Xuejing made bearings were polished with natural diamonds, but the impurities contained in them would cause a deviation in accuracy of the workpiece, resulting in a high waste rate.

Therefore, a grinding wheel must be made.

Most of the grinding wheels in later generations were made of steel, jade and diamond as raw materials, and were made of ceramics and resins as adhesives. The two types of stones were easy to solve, but the problem was the adhesive.

Resin is very difficult. First of all, it is lacking in northwestern Shanxi, and secondly, it requires chemical treatment to meet the requirements of use. And ceramic bonding agent... Qin Chuan doesn't know how to do this thing.

Fortunately, he thought of something: asphalt.

Tar is produced in the coke refining process. Several coke plants built by Qinchuan have production lines for condensing and refining tar. The black thing left after tar distillation is asphalt.

Because the output is not high, Qinchuan did not use it to harden the main roads, and only paved asphalt roads in coking plants.

After thinking of this, Qin Chuan asked Chen Zhan and Li Xuejing to use this thing for experiments. First, they mixed it with diamond powder separately as a bonding agent, pressed it into a grinding wheel, then dried and baked, and then added various materials to it, including steel and jade powder, iron powder, copper powder, clay powder, ceramic powder, glass powder, lime powder, etc.

In the end, he successfully made a grinding wheel that meets the requirements, the materials were diamond powder, copper powder, glass powder, and a small amount of steel and jade powder.

With a grinding wheel, everything else is easy to do.

As for the fine grinding of steel balls, we can only rely on continuous testing and improvement of precision grinders, but the scrap rate will definitely remain high, and we can only rely on increasing production to meet demand.

After the design of mass production of bearings was basically determined, Qin Chuan began to prepare two new factories.

One is a lathe factory and the other is a grinding wheel factory. The former must be of a large scale, while the latter can be manufactured in small-scale workshops.

Qinchuan plans to centrally produce all lathes and corresponding accessories, including boring machines and threaded rotary machines required by gun factory.
