The two tracks of the iron yard have been officially put into use, Chen Zhan has returned to the artillery factory to continue making cannons, and Yan Sanqi has stayed in the iron yard to continue casting the rails.

Qinchuan should lay railroad tracks between coal mines, coking kilns and iron yards, between iron mines, gravel yards, fine material yards and Dajian furnaces, including the inside of the mines.

There are also Hongli Mountain mines, brick factories, black mountain lime factories, and cement factories, which also have to lay railroad tracks.

It is tentatively estimated that all mining industries will save at least 30% of their manpower by replacing the original mode of transportation with rail cars.

In the future, he also wanted to lay the railroad tracks between Montenegro and Lou Fan, because Lou Fu's gun factory, gun factory, and blacksmith shop all used coking coal and iron, and it was very difficult to transport them out of Montenegro.

After the production of rails stabilized, Qin Chuan and Yan Sanqi took the time to start making iron pots.

The iron pot can be divided into two kinds: pig iron and wrought iron, the pig iron pot is cast with a mold, which is thicker and heavier, and more brittle, and the heating is also slow, but the heat is maintained for a long time after heating, which is suitable for stewing.

Wrought iron pot is made of wrought iron, thinner, better toughness, fast heating, but heat dissipation is also fast, it is necessary to continue the fire to maintain the heat, suitable for frying, and the cost of wrought iron is high, forging is more labor-intensive, and the price is more expensive than the same size of pig iron pot.

In this era, the people basically used heavy pig iron pots, and large families and restaurants would use wrought iron pots to fry vegetables.

According to Yan Sanqi, the Guangdong iron pot is a kind of red clay mold made of red clay by adding rice husk and grass, etc., and then polished it with an unknown local stone.

This kind of pot is very light and thin, the thinnest can only be two millimeters, and the surface is smooth, beautifully manufactured, does not absorb oil, and is very practical and durable, it has become a tribute to the Ming Dynasty, and has also become a sought-after item sought after by Mongolia, Japan and even Europeans.

At that time, the eunuch Wang Zhen cut the price of the horses sent by the Mongols to eighty percent, and the Ming court also limited the number of Mongols entering the customs and trade, and also limited the number of pots bought, fearing that the Mongols would use the pot to melt the armor.

When the Mongols came to negotiate, they also complained that the pot of the Ming court was too expensive, and one pot was worth two horses, that is, about one or two silver.

The two sides failed to negotiate, and in the end the Mongols got started.

Nowadays, grain and other prices are soaring, and the price of iron is naturally rising, a small five-pound pot in the north will be sold for one and a half cents, and the three-foot-wide large iron pot weighs less than fifty catties, and can be sold for one or two or eight dollars of silver, and the bulk trade will be about two to forty percent lower.

The pot is a money-making business, and Qin Chuan must make it.

Not only to make money, but also to develop the steel industry, to create cold rolling and hot rolling technology, in the future to replace labor with machinery.

The pot he wants is intended to be hot-rolled, or liquid-rolled.

Because pig iron is brittle and cannot be rolled, it should be rolled before the molten iron solidifies.

The method is very simple, that is, to make a pot mold with wrought iron, and a semi-circular rolling hammer slightly smaller than the pot mold, the two should be installed in a vertical state, and the lifting of the rolling hammer is controlled by rails.

The carbon content of the molten iron should not be too high, otherwise the pot will be very brittle, after the molten iron is boiled, it is first cooled to a gelatinous shape, and then poured into the pot mold, and the semi-circular rolling hammer is rolled into the pot mold, and the gelatinous molten iron is pressed into a pot.

The pot mold and the hammer will be coated with a layer of wax in advance to avoid sticking with the molten iron, and then lift the hammer when the iron pot is cooled, take out the iron pot, polish the pot surface with a fine stone, and install the pot ears.

This set of rolling equipment, Qin Chuan directly named the pot rolling machine, at the beginning of the construction of three sets, and Yan Sanqi spent a few days with different carbon content of molten iron, and different rolling time to do experiments, and finally came up with a set of optimal data.

It stands to reason that Lou Futie is of better quality than Guangtie, and the pot he made is better than that of Guang Pot, but he specially asked Luo Wentian to buy a few Guang Pots and come back to compare, and found that the pot he made was >> than the Guang Pot

It's about the same, not worse than a wide pot, but it's not much better.

It is estimated that the red mold of the Guangguo method contains some specific substances, and when casting, it reacts with molten iron to form a certain substance in it, which makes the Guangguo unique.

Qin Chuan's requirements are not too high, they are not worse than Guangguo, as long as they can be sold at the price of Guangguo.

After all, his manufacturing process is time-saving and labor-saving than that of the canton pot, and it is also more cost-free, just pour the molten iron into the pot mold, and roll the rolling hammer down.

After the success of the test, Qin Chuan immediately decided to set up a pot factory in Montenegro, build a batch of pot rolling machines, and start mass production of iron pots.

Fifty catties of pig iron can only be sold for seven dollars of silver, and after simple processing, it can be sold for about one or three yuan after being turned into an iron pot.

He wanted to seize the market share of Guangguo in the north, and let the agents go to sea from Shandong and sell them to the little Japanese and Europeans, as well as Yarkand in the west and Khalkha in the north, as long as they were not sold to Jiannu and Jiannu's lackeys.

This pot can bring him a steady stream of silver and grain.

In addition to this, he also had to develop the hot and cold rolled manufacturing of other iron tools to save labor and reduce costs.

Once the steel manufacturing industry flourishes, it will usher in the industrial age.

……

The 50,000 acres of cultivated land in Jingle and Lan counties have basically been sown, and even the 8,000 acres of fertile land in Ninghua Wangfu have also been sown.

Anyway, after the crops are ripe, no one can cut the grain, and the people of the Ninghua Royal Mansion will kill one by one, and two will kill one pair.

Seizure is over.

On the tenth day of the first month of June, someone came from Taiyuan, who was sent by Du Yingtang, and sent a holy decree and an official document.

The holy decree said that Qin Chuan must be allocated before June 15, and go south to Liaozhou to listen to Xu Dingchen's dispatch to suppress bandits, and punish them severely after the deadline.

The official letter said that Qin Chuan should quickly send troops to exterminate the bandits in Yunzhongshan, and then immediately go to Taiyuan to receive the military rations that had been prepared, and then go south to Liaozhou to listen to the dispatch of Lord Xu of Futai.

After receiving these two letters, Qin Chuan called his subordinates for a meeting.

The focus of the discussion was not when to send troops, but whether Zhao Sandao should be cleaned up.

Zhao Sandao has also been entrenched in the Yunzhong Mountain area for several years, the old nest is in Wufeng Mountain, about 70 miles northeast of Jingle City, located in the middle of Jingle and Xinzhou, and the boundary belongs to Xinzhou.

Last time, Zhao Sandao came to join in the fun and attacked Mengjiazhuang, but he was very miserable by Qin Chuan, and there were less than a hundred people left under him at that time, and he fled back to Wufeng Mountain in embarrassment.

Since then, Zhao Sandao didn't dare to step into the Loufu realm again, and after Qin Chuan conquered Jingle County, this guy didn't dare to enter the realm of Jingle anymore, and instead ran to the east of Huohuo Xinzhou.

The reason why Qin Chuan hasn't cleaned him up is because this guy is far away, seventy miles away from Jingle City, and that guy doesn't dare to come to his own territory to spread wild.

Second, because there are only two mountain roads to go from Xinzhou to Jingle, Wufeng Mountain is stuck on one of the roads, and Zhao Sandao can help him block the officers and soldiers who come from the northeast to copy the mountain road.

Now, there's no need for that guy to stay.

After only discussing for a short while, Luo Daniu and the others unanimously agreed to clean up Zhao Sandao.

The next day, Qin Chuan sent Feng Yilong to lead five hundred Feng Shan battalions to Jingle City, obey Li Dingliang's dispatch, and exterminate Zhao Sandao.

At the same time, Qin Chuan asked Luo Daniu, Zhao Wu, Liao Sangun, Ren Liang, Huang Liuxi and others to prepare 1,500 soldiers and horses and five days of grain and grass, and asked Lao Huang and Bobcat to go to Taiyuan to inspect the grain and grass prepared by the local government.

On June 15, they set out to the south to suppress the bandits.
