The bright moon is high and as bright as a plate. Although it is late at night, the crowds in the square are still surging. People who have been busy for more than half a year are enjoying the rare peace and prosperity. In addition, the couple singing with Xu Huang, Huliya, Zhao Xing and Diao Chan on the stage greatly aroused the desire of the red men and green women to go around under the beautiful moonlight. The hosts of that night, Zhao Xing and Diao Chan, had already left with the guests and returned to their newlywed love nest.

"Well...oh..., good brother... be gentle..." The voice of Diao Chan's bone-eating voice came from the room.

"Girl, be patient for a moment...give me..." Zhao Xing's comforting voice came.

Zhao Xing remembered the lessons from the previous few days tonight. No matter who comes to persuade him to drink, he will push his brothers on the heads, greatly conserving his combat effectiveness. So at this moment, he is quite domineering in the wedding room.

According to Zhao Xing's meaning, in the backyard, Myolie Wu and Diao Chan's rooms are located on both sides of Xu Wanting, which not only highlights the status of the eldest lady, but also does not allow Myolie Wu and Diao Chan to compete with each other in secret.

"Bad brother-in-law! Bad brother! You'll kill someone with such a loud noise!" In Xu Wanting's room, the two sisters were already embarrassed to hear the laughter from Zhao Xing and Diao Chan who were working hard next door, and their faces were red and only to their necks. Xu Wanlin was still virgin, without any human affairs, and could not resist the sound of spring. She couldn't help but half-cover her ears, tightly clamped her legs that had already wet her underwear, and scolded Zhao Xing insincerely. Xu Wanting hid directly in the quilt, covering her head with the quilt, so that she would not see her seductive expression "The door is only willing to open for you" at this moment. Myolie Wu next door still heard something vaguely, and she was restless all night.

It seems that for a while, Zhao Xing has been busy! Fortunately, Zhao Xing insisted on exercising every day, practicing martial arts, and developed a strong and good body, not a silver-like wax gun tip. Otherwise, the tigers in the backyard would really grind him into a needle.

There is a saying that goes, "If there is no diamond, you won't take on porcelain work!" Zhao Xing, who worked hard, was preparing to match all his generals with diamonds! Early in the morning of the next day, he gathered all the blacksmiths in Chouhu City on an empty high ground and held a very important on-site meeting. So, what content did they hold? The answer is how to improve the small blast furnace steelmaking technology!

Having written this, Nandao will briefly explain to you the process of iron ore to pig iron and then to refined iron (steel): iron ore is sintered and turned into spherical iron ore powder, and then removed most impurities such as sulfur, phosphorus, silicon and other magazines and excessive carbon through the blast furnace, and becomes iron. Iron is further purified and the content of impurities is further reduced, and it becomes steel. I will briefly explain to you the principle of steelmaking in small blast furnaces: ordinary people use clay and bricks to build small blast furnaces, use iron items at home as raw materials, and use wood and charcoal as fuel to reduce the carbon content in iron.

The specific process involves many chemical and physical reactions and changes. If you write it in detail, you can open another book, so I won’t go into details here. The same sentence is the technical details. I am tired of writing, but you are even more tired of reading.

According to historical research, China invented pig iron smelting technology around the sixth century BC. In the Spring and Autumn Period, the two processes of "block iron smelting" and pig iron smelting were produced almost simultaneously. The "hundred steel smelting" technology emerged in the Western Han Dynasty, that is, by increasing the number of repeated heating and forging, the quality of steel was greatly improved. In the middle of the Western Han Dynasty, steel smelting appeared, and the pig iron was fryed to a semi-liquid solid state, and stirred, using iron minerals and oxygen in the air for chemical reactions to decarbonize, and eventually became steel products. It can be said that by the Eastern Han Dynasty, China's steel smelting technology was relatively mature and complete.

In the last life, Zhao Xing heard his father talk to him more than once about "Making steelmaking in the country, catching up with Britain and surpassing the United States". He also learned the principles in high school chemistry class, and repeatedly discussed some of the key points with his comrades. The so-called "Making steelmaking in the country" naturally follows the methods passed down by our ancestors. So let's discuss the feasibility of Zhao Xing's plan to promote ironmaking and steelmaking technology reform in Shangdang in the late Eastern Han Dynasty.

In fact, Zhao Xing did not think about improving the "civilized steelmaking" technology to a level that can be compared with modern steel smelting technology. Without relevant supporting equipment, no temperature control, no electricity, and no mechanical automation, that is simply impossible. Zhao Xing plans to improve several key links in ironmaking and steelmaking.

First, change the idea of ​​people's light forging and recasting in this era. What does it mean? It is to guide everyone to repeatedly heat and forge steel with high impurities like an island country who is good at making sharp long knives, instead of following the old idea of ​​bronze casting technology and investing too much energy in casting. Zhao Xing has a support, don't forget that he has made a water truck. He can guide craftsmen to convert hydraulic power into continuous forging power. This only involves physical machinery manufacturing technology, which is easier to deal with.

Second, use coal with higher calorific value and continuous and stable heat as fuel! In ancient China, a large amount of coal smelting steel began in the Song Dynasty, and Zhao Xing had to advance this process. If he sleeps on the boundaries of Shanxi, a major coal-producing province, and does not know how to use the resources under his feet, Zhao Xing would be stupid.

Third, improve the combustion chamber and add a heat storage chamber and a large blower. The purpose of improving the combustion chamber is to use fuel more efficiently. The purpose of adding a heat storage chamber is to first compress and heat the air, and then blow it into the furnace with a blower, further increase the temperature in the furnace and promote the combustion and discharge of impurities.

Fourth, improve the technical means of steel frying and steel frying. In Zhao Xing's opinion, the quality of the steel from the blast furnace is too poor. It must be frying first, and then repeatedly forged to truly achieve "frying into steel for a hundred and forged into steel for a hundred and forged into steel for a hundred and forged into steel"!

So what is the purpose of Zhao Xing's steelmaking? The answer is very simple, to make weapons and armor with higher strength and toughness, as well as key equipment. In addition, Zhao Xing did not intend to transition the lives of the people from bronze objects to the steel era at once. Zhao Xing does not currently have so many resources and labor, nor does it in any country in the world. In other words, the purpose of blast furnace steelmaking was ultimately used by Zhao Xing to arm the army for self-protection.

A group of old craftsmen who made iron and forged steel surrounded Zhao Xing, listening to his continuous explanation on the ground, each of them was shocked in their hearts. It is said that Zhao Xing, a hyperbolic star in the Crouching Tiger City, descended to earth, and now everyone believed it. Some of the advanced ideas proposed by Zhao Xing are not seriously out of touch with the technology of this era, and some are even closely related. Many of these blacksmiths are old-fashioned, so they can naturally understand the key and principles. Especially Zhao Xing told everyone with certainty that the key to smelting iron into steel is to remove some magazines that cannot be seen from the burning of red iron, and then everyone suddenly realized that the key to steel making is to remove the key to steel from the reddish iron, and then everyone suddenly realized that the key to steel making is to remove the roughness and retain essence!

After listening to Zhao Xing's guidance, looking at the blast furnace structure diagram that Zhao Xing had already drawn on paper, everyone had a direction and goal in their hearts, and began to study and prepare in groups according to their respective areas of expertise. The entire Wohu City attached great importance to and supported the steel smelting group led by Zhao Xing himself, asking for people and things to give them. They were all looking forward to the release of the good steel described by Zhao Xing as soon as possible.
