After beating everyone and dealing with everything, Zhu Pingjin, who was rarely relaxed, climbed the hill behind Sanhui Town and looked at the beautiful scenery of the confluence of the three rivers, accompanied by Shu Guoping, Luo Jingyun and Dong Kezhi. &1t;/p>

Sanhui Town is a small mountain town and a large wharf. The local products and wood in Dazhou and Bashan, as well as the daily necessities and salt in the hinterland of Sichuan, all have to pass through the hub of Sanhui Town. In addition to logistics and commerce, Sanhui Town also produces coal. &1t;/p>

Dong Kezhi of Qujiang Tong introduced to Zhu Pingjin that there are dozens of coal kilns in the north and south of the Zhouhe River, that is, Huidong, Huibei and Huinan, which can produce hundreds of thousands of catties of coal annually at the peak of the peak period, and are important coal-producing areas in the upper reaches of the Qujiang River. Because of the long mining years, the longest coal roadway can reach 100 zhang. When digging coal, the most feared thing is the overflow of toxic smoke, which can be a kiln or die. There is a set of mature methods to deal with toxic smoke here, that is, to use hollowed out bamboo pipes to discharge toxic smoke, &1t;/p>

Interestingly, there is also a Sanhui town with the same name and surname in Hezhou, but Sanhui Town in Hezhou is not named after the confluence of three rivers, but after the convergence of three mountains. The so-called three mountains, namely Zhongliang Mountain, Jinyun Mountain and Yunwu Mountain, the three mountains converge here to form Huaying Mountain, so it is called Sanhui. What's even more interesting is that the town of Sanhui in Hezhou also produces coal, and the scale is larger than here. It's just that because the river that flows through the town is too small to carry large boats, the production is limited by the amount of traffic. &1t;/p>

In Sanhui Town, Hezhou, there are thousands of miners who make a living from coal mining. In the Hezhou group training, there were probably dozens of miners from Sanhui Town, Hezhou. &1t;/p>

Since the two Sanhui towns are located in the same Jialing River basin, the coal produced will be collected along the Qujiang and Jialing rivers to Beibei Town (Note 1) at the mouth of the northwest gorge in Chongqing, and supplied to all counties in Chongqing. &1t;/p>

…… &1t;/p>

Dong Kezhi's introduction immediately attracted Zhu Pingjin's great attention. &1t;/p>

At present, there are two main sources of steel needed by the Firearms Bureau and the Machinery Bureau. The main source is the iron factory of Shiquan Lao Wang in Gaozhou, Xufu (Note 3). &1t;/p>

Yunlian and Jue counties in the south of Yibin are rich in iron ore and coal, and they have the geographical convenience of Nanguang River. Eager to get rid of poverty and live a prosperous life, Shiquan Yizong funded the construction of an iron factory on the banks of the Nanguang River. In order to hide people's eyes, Shiquan Lao Wang also sent the iron factory to the name of Wang Qi, a local iron boss. After Shiquan Lao Wang took the initiative to hand over the Gaozhou Iron Works to the bulk of the plant, because of the limited output, Zhu Pingjin did not hesitate to invest a lot of money in the technical transformation and expansion of the Gaozhou Iron Works. &1t;/p>

According to the blast furnace sample drawings and descriptions drawn by Zhu Pingjin, Wang Qi thought a lot. Not far from the old factory, he built a large blast furnace under a cliff near the river. In this way, the raw material transportation can be carried out with the help of water transportation, and the blast furnace feeding can be directly carried up the mountain. Due to the high height of the furnace, the charge enters the blast furnace and hedges with the rising hot gas flow for a longer period of time during the fall. The charge heats up quickly, the furnace body temperature is high, and the output naturally increases. &1t;/p>

The output has gone up, and the quality has to keep up. Zhu Pingjin strictly prohibits the direct use of raw coal in blast furnace feeding. The raw coal must be washed to remove the unhelpful and harmful coal gangue, and then the coal is made into coke in a coke oven to remove harmful impurities such as ash and phosphorus and sulfur. &1t;/p>

Near the large blast furnace is an improved iron pond made of refractory bricks. In order to prevent the fried iron pond from cooling as quickly as the old fried iron pond, so that the molten iron condenses into an unstirring paste, the opening of the fried iron pond is reduced, the depth is increased, and the contact area with the air is reduced. He also added three fire lanes similar to the palace warming earth dragon under the improved iron pond. In this way, the improved iron pond has become the most primitive open-hearth, which can use the charcoal furnace and blower to continue to heat the molten iron, and use limestone to combine with phosphorus, sulfur and silicon and other elements to facilitate the removal of steel slag. &1t;/p>

However, the renovation and expansion of the Gaozhou Iron Works could not be completed in just a few months. Even if you use silver and people to pile it, it will take time. The huge demand for steel in the military equipment and civilian markets has led to a shortage of iron and high prices. This situation has affected the production of vital weapons. &1t;/p>

For example, during the war in northern Sichuan, the Firearms Bureau quickly increased the production of firearms, and many family members and even children joined the production army to do some rough work that required strength but did not require technology, such as shaking the lathe and pulling the bellows. However, due to the shortage of raw materials, it is always difficult for the output of firecrackers to break through the 20 per day mark. The rest of the important product production and research tasks, such as the trial production of iron cannons, had to be completely stopped. &1t;/p>

The Firearms Bureau and the Luzhou side are jointly issuing a report requesting that a new arsenal be built at a site in Luzhou to expand the scale of weapons production. But if we don't solve the problem of producing raw materials, then all plans to expand production will be frustrated. &1t;/p>

The Firearms Bureau and the Machinery Bureau, which were waiting for the rice to be cooked, had to buy products from small iron factories in the countryside on the open markets in Chengdu, Yazhou, and other cities. The iron produced by these small iron factories is of varying quality, and the overall quality is poor. After being transported back, it must be re-refined by crucibles, or even twice, in order to eliminate the coarse and retain the fine, as raw materials for the processing of fire guns, iron cannons, bearings, steel columns, and steel plates. &1t;/p>

As for the scrap steel on the market, Wang Kunshan and Yang Neng began to collect and store early. Led by leading enterprises, the street vendors have added a new business - buying scrap steel from the people. &1t;/p>

…… &1t;/p>

In Zhu Pingjian's previous life, Chongqing was the largest heavy industry city in western China, and the steel industry and the steel-based machinery processing industry had been the leading industry in Chongqing for a long time. &1t;/p>

As we all know, the steel industry needs two basic raw materials: coal and iron ore. In the very inefficient logistics environment of the Ming Dynasty, large-scale steel production must rely on waterways, so the steel industry and the mechanical processing industry must be located near the water wharf. Chongqing is the largest and best water wharf in Sichuan, and the conditions for heavy industry are unique. &1t;/p>

To develop heavy industry, coal and iron mineral resources are the foundation. Sichuan has never lacked coal mines, nor iron ore, and the steel industry and machinery processing industry have a lot to offer. After hooking up with Liao Daheng, Zhu Pingjin sent someone to check the archives of the chief secretary. According to the tax data of the feudal divisions, there are as many as 19 iron ore mines in Sichuan alone (Note 2). The large and small workshops of smelting steel are almost all over Sichuan. Even in Tibetan areas, there are many blacksmithing workshops. The steel knives and bayonets produced by the archery furnace have an average monthly amount of silver of tens of thousands of taels. &1t;/p>

Zhu Pingjin, who comes from the future world, knows that these coal mines and iron mines are generally small in scale, low in output, and huge in labor intensity. Safety measures are backward, and accidents involving dead people and abandoned wells are frequent. &1t;/p>

The workshop-style steel production method, with its low output and poor quality, could not meet the needs of the rapid expansion of the scale of the war and the thriving needs of the private economy, and was even more incompatible with the future large-scale industrial system planned by Zhu Pingjin and his wife. &1t;/p>

Similar to the mode of production, the steel market is divided by a vast and complex geographical area, turning into a small market with little information and no communication with each other. From the point of production to the final consumer, logistics costs are extremely high. As soon as there is a large-scale purchase, the local market price immediately fluctuates violently. &1t;/p>

Only by rebuilding a new large, modern steel plant can we produce a large amount of high-quality steel. Only by mining minerals with large reserves, high grade and suitable for mining can we save manpower and material resources and match the production capacity of modern steel plants in a short time. Only by establishing a unified and transparent steel market and logistics system can we carry out steel circulation and trading efficiently and cheaply, and make steel the main category of the trade war. &1t;/p>

…… &1t;/p>

There are many coal mines in Sichuan, but there are not many large reserves of iron ore, one in Qijiang and one in Panzhihua. Panzhihua is now a Yi district, and Zhu Pingjin does not have the 8,000-ton high-energy explosives as powerful as an atomic bomb to tear off the 20-meter-thick surface cover of Baobao Mountain. &1t;/p>

When Zhu Pingjin thought of this, he immediately asked Dong Kezhi if there were iron mines near Hezhou and Chongqing. Dong Kezhi thought for a moment before replying, he had heard that there were displaced people in Qijiang County in the south of the Yangtze River who dug mountains and made profits by smelting iron, and there were thousands of people (Note 4). &1t;/p>

Without waiting for Dong Kezhi to finish speaking, Zhu Pingjin immediately ordered Luo Jingyun to record and ordered the Firearms Bureau to stop the site selection in Luzhou and change the location to Chongqing. The specific site selection range is in Ba County, north of the Yangtze River, and west of Chongqing Fucheng. It is necessary to be able to build wharves, build blast furnaces, expand the industrial chain, and develop the mechanical processing industry with steel as raw materials. The planned area of the factory site shall not be less than 100 hectares. &1t;/p>

One hundred hectares of land, that's 10,000 acres. Coupled with the factory on the ground, I don't know if the investment of hundreds of thousands of taels of silver can be stopped. Zhu Pingjin suddenly issued four "can" orders, which made Dong Kezhi, a Hezhou gentry who didn't know much about the temperament of the prince, stunned. How did he know that Zhu Pingjin was very familiar with Chongqing Dadukou and Heavy Steel in his previous life. After the separation of Sichuan and Chongqing, Deputy Director Zhu returned to Heavy Steel for inspection. When Deputy Director Zhu returned to the hotel, he secretly shed tears for a man who would never flick it. Because what Deputy Director Zhu saw was a steel enterprise in a period of decline, a large group of old employees of state-owned enterprises who had paid the best years of their lives, but were still destitute. &1t;/p>

However, Shu Guoping and Luo Jingyun only smiled slightly at Zhu Pingjian's order. They knew that the prince of the Shu Domain, who was known as the boy of scattered wealth, must have thought of some opportunity to make a lot of money. &1t;/p>

There are differences in the times, and there are advances in technology. However, in the long process of human evolution, hundreds of years are only a short moment. The high level of human IQ, how much change can the Ming Dynasty and Zhu Pingjian's previous lives have? &1t;/p>

Shu Guoping and Luo Jingyun, two smart people, are right. &1t;/p>

In the Ming Dynasty, heavy industry, just like the Internet industry in Zhu Pingjin's previous life, was an emerging industry that could completely change the state of human life, an outlet that could blow fat pigs around, and a powerful force that a person and a group could conquer the outside world! &1t;/p>

Whoever can preemptively enter this industry and rule this industry will have the wealth of the rich country and the power to look down on the world! &1t;/p>

Where the three rivers converge, the three of them have their own thoughts. &1t;/p>

At this moment, a fast horse carrying a knight carrying a flag carried through the smoke-strewn ruins of Sanhui Town, and rushed straight to Zhu Pingjian's feet. Zhu Pingjin knew that there must be some military information. He shouted around and led the group down the mountain. &1t;/p>

Note 1: Beibei Town is a name that only existed in the Qing Dynasty and was borrowed first. &1t;/p>

Note 2: There are historical records. &1t;/p>

Note 3: The current Gaoxian county governance is actually the Qingfu county governance of the Ming Dynasty. Gaozhou in the Ming Dynasty, in the old city of today's Gao County, that is, Wenjiang Town. &1t;/p>

Note 4: The mining history of Qijiang iron ore may be longer than that recorded in the historical materials of the Ming Dynasty. &1t;/p>
