First of all, the leather folding bellows have been transformed into wooden piston bellows. Leather is prone to aging and is difficult to replace and repair. This piston type wooden bellows has a simple structure, and it is very easy to repair if there is a problem, which greatly increases the air intake.

As a poor child who grew up in the countryside in the 70s of the 20th century, Wang Song is very familiar with the piston wooden bellows used for cooking in the countryside.

Therefore, when he first saw the leather folding bellows on the iron ore he bought, he moved on the idea of retrofitting the wooden piston pull-out bellows. At the same time, on the periphery of the furnace, a regenerative chamber has been built.

The regenerator is connected to the air vents on both sides of the bellows, so as to ensure that the air entering is hot air, which greatly increases the combustion temperature. With the improvement of the piston bellows, the air volume has also been increased, and the speed of refined coal combustion has been accelerated.

The most special thing is that when making iron, Wang Song had lime and quicklime added to it as a slag remover to remove sulfur and phosphorus from iron ore. Since his furnace is made of clay bricks, not an acid furnace, he does not have to worry about the reaction between the slag remover and the refractory bricks of the furnace.

Although they are only theoretical, the masters are in the people, and these craftsmen will immediately turn their ideas into reality as long as they have a little bit.

"In fact, the use of this is not particularly great, if the current refining furnace is too small, it can only change the speed of life, but cannot increase the capacity."

Wang Song said to the stunned potters next to him: "The iron factory is built by the river, we can use water instead of manpower, which can not only speed up the speed of coal washing, but also save more silver!"

"Who is saying behind his back that Wang Daguan is crazy and has a bad brain?"

Dong Ping's eyes widened and said: "Just you birdmen, one by one sitting in the well and watching the sky, you know that there are people outside the world, and there is a sky outside the sky!" Haven't you come up one by one to make amends?"

"Kowtow willingly!"

One potter knelt down, and the others quickly bowed down. The potter at the head said loudly: "The big officials are the gods in the sky, and the little people are blind, I hope the big officials will forgive their sins!"

Wang Song glared at Dong Ping, hurriedly stepped forward, asked everyone to get up, nodded and said, "Everyone, get up, don't listen to my brother's nonsense!"

Wang Song entered the iron-making furnace, the red molten iron continued to flow out through the casting trough, and Li Laohan was fiddling with the formed iron ingots. Seeing Wang Song come in, he said excitedly: "The big official is really amazing!" The iron ingots that come out today are all high-grade good iron, and the amount of two days a day is really amazing! ”

"Great official, you are the ancestor of iron smelting!"

Master Hu nodded again and again: "My old man has been refining iron all his life, but it is not as good as the fur of the big officials, the big officials are really young heroes and heroes, and they can't accept it!"

"The two masters, I just came up with an idea, but the two masters did it, thank you very much!"

Wang Song nodded and said, "From now on, the two masters will increase two taels of silver every month, which can be regarded as a little heart!" The weather is already hot, and the two masters still have to take care of their bodies! ”

The two of them were happy in their hearts, and Master Li said loudly: "Great official, you are really a bodhisattva!" If the little lady of that family follows you, she will enjoy endless blessings for a lifetime!"

Master Hu also complimented beside him: "If the Wang officials want to recruit wives and concubines, I'm afraid this little lady's team will have to line up from the gate of Wu'an County to the Daimyo Mansion!"

Wang Song also laughed, the jokes of the two old men really made him a little happy.

His eyes glanced at randomly, but he found that at the door of the refining furnace, there was a group of people looking inside, led by a tall woman, looking at the figure and temperament, Wang Song couldn't help but move in his heart, it seemed that an old man came.

In the furnace workshop, it was steaming and scorching, and twenty or thirty craftsmen were busy. It was already hot in May, and the temperature in the ironworks was even hotter, but the people around the furnace had to wear a tight-fitting single coat with sleeves and trousers tied up to prevent skin burns.

The style of the single clothes is exactly the same, simple and clear, without any redundancy. The hands and ankles are all narrow, and all of them have to be tied. Everyone had a hat around their neck with a strap on their head and a mask on their mouth and nose. In the furnace workshop, hair is not allowed to show out, also for safety reasons.

The red molten iron flows into the molds to form a cylindrical warp and weft engraved shell with a length of 9 cm, a diameter of 7 cm and a shell thickness of 5 mm. Cylindrical shells are loaded with 27-centimeter-long wooden handles, then assembled with gunpowder and fuses, and finally sealed for war.

This cylindrical iron case with a wooden handle is called a grenade, which is an imitation developed by Wang Song based on the M24 grenade of later generations. The difference is that the wooden handle shot by Wang Song is solid, there is no fire pipe pulling device, and there is no mercury thunderate detonation.

The last model of the German M24 grenade, also known as the "potato masher", is to take a solid wooden handle, install the fuse on the front of the bomb body, and set the length according to the burning time of 5-6 seconds, so that after the soldier throws out the grenade, the opponent will not have time to throw it back.

The design of the M24 grenade is very reasonable, the throw distance is long, and the throw is very accurate. The M24 is designed with a wooden handle, and thanks to the lever principle, a lightly trained soldier can throw it far and accurately, basically reaching about 60 meters, and up to 80 meters or so.

In terms of the method of producing grenades, Wang Song borrowed from the production process of "seven people's backs", which everyone knew in later generations, but it was more refined.

The division of labor of seven people is generally three people for modeling, iron, and pouring, one person pulling the air box, two people making the fire pulling device and assembling, and one person processing the bullet handle. If the giant is skillful and closely coordinated, it will only take about half an hour from the topic of ignition to the first grenade being made. The manufacturing process is divided into casting bullet shells, making fire-pulling devices, processing bullet handles and assembling them.

Wang Song is the same now, modeled with iron film, which is easy to carry, durable, and suitable for mass production.

However, when casting the shells, it is necessary to form an empty chamber with a sand core composed of 75% sand, 15% clay and 6% sawdust, plus 4% water.

In the mill where the handles are made, five or six locally hired carpenters are sawing branches into round sticks, which are then placed on knife holders to process into identical cylindrical handles. These cylindrical wooden handles are not hollow, but solid.

The Orizuki Show, who was watching, apparently didn't know the purpose of the cylindrical shell she had created, she just wondered what it was. Seeing Wang Song looking over, Zheyuexiu nodded and walked out of the ironmaking workshop.

Wang Song followed out suspiciously, but found that Zhang Heng was outside, talking to the Zhiyuexiu just now.

Seeing Wang Song come out, Zhang Heng hurriedly went over and said, "Great official, this is a messenger sent by Zhang Xianggong, let you go over to talk."

Wang Song could see clearly that the Folding Moon Show in front of him was the woman in black that he and Zhai Liang saw in Zhang Hao's army that day, but he didn't expect that she was Zhang Hao's messenger. Wang Song stepped forward and hugged his fists and said: "In Xia Wang Song, I have seen the honorable envoy!"

The woman waved her hand and said, "Commander Wang doesn't have to be polite!" Originally, I came early in the next meeting, but because I had to wait for the will of the imperial court, I delayed it for a while, and I ask the king to ask the commander to forgive me!"

Wang Songlian said that he didn't dare. The woman suddenly raised her voice and said, "The commander of the Hedong Loyal and Righteous Army makes Wang Song obey the order!"

Everyone was shocked, Wang Song knelt down first, and the people next to him also quickly knelt down.

Wang Song couldn't help but wonder in his heart, this woman didn't need to set up a table by herself, nor did she need to burn incense in the furnace by herself, so she began to read the edict directly under the shade of the tree outside:

System said: Since I ascended the throne, every time I think about the alliance of the Yuanyuan, Yanyun has not recovered, often crying, unable to sleep at night, only thinking of waving the Northern Expedition to restore the homeland. I didn't expect the Jurchen Fanzi to commit the border, and I heard that Wang Song, Zhai Liang and others, Su Huai were loyal, resolute and self-motivated, and had a little more than enough wisdom, galloping across the field, not afraid of death and injury, killing more than 1,000 Hu Nu, saving the country's important ministers, revitalizing the spirit of the court, and destroying the prestige of the Jurchen Fanzi. I am very relieved, and now I specially issued a jade decree, specially enshrined Wang Song as the Hedong Road pacification envoy, Zuo Wu doctor, and Liaozhou Assassin History, Zhai Liang as the Hedong Road pacification and recruitment deputy envoy, martial arts doctor, and the rest of them have their own blockades. When the edict arrives, don't lose your heart, restore the rivers and mountains, restore the homeland, the monarchs and ministers know each other, and the eternity will be long. Therefore, the edict is hereby informed, and it is advisable to know about it. On May 21, the first summer of Jingkang.

Wang Song was also happy in his heart, shouted three times long live, and then got up from the ground, and became the militia commander of Hedong Road in a daze.

Zheyuexiu said solemnly: "The king recruits the envoy, congratulations!"

Wang Song hurriedly hugged his fists and said: "Thank you for your kindness, thank you Zhang Xianggong, thank you for your honorable envoy!" In the next unforgettable, dare not forget! ”

"You don't have to be polite, get up quickly!"

Zhi Yuexiu waved her hand and said politely: "I won't tell you, Yao Xianggong and Zhang Xianggong have been defeated." Now the Song army is collecting the rout, waiting for an opportunity to counterattack Taiyuan. But you're right, the little Xianggong is now safe and sound, and he is recruiting the old department in Jingcheng, accumulating strength, and when the time comes, he will attack Taiyuan. ”

Wang Song sighed secretly. I was able to save the planter, but I didn't change the inherent trend of history.

Yao Gu and Zhang Hao were still defeated with one blow, and then Yao Gu would be demoted, and his rumor-spreading general Jiao Anjie would be killed.

Sure enough, Zhe Yuexiu continued: "Now that the imperial court has recalled Yao Xianggong and demoted him to Guangzhou Mansion, his former military commander Jiao Anjie was killed by Li Gangxianggong. In place of Yao Gu is Xie Qianxianggong, who is now stationed in the Weisheng army. ”

"Unwinding the submarine will definitely fail!"

Wang Song shook his head and said: "Not only Yao Gu and Zhang Hao, but also the Lin Mansion Army, Liu Guangshi's Yan Army, plus the Minor Princess, all the armies of the imperial court will be defeated or annihilated one by one!"

Zheyuexiu couldn't help but be stunned. This Wang Song is an unpredictable person. He said that the armies of the imperial court would be defeated, and whether it was really an unknown prophet.

If so, how can I go north to find my father?
