Zhu Hongsan knew that this matter had been five days later, Ma Xiaofang knew that he could not go out and entrusted his brother Ma Jingyuan to his lover to inform himself.Zhu Hongsan listened to Ma Jingyuan to tell the whole thing, and smiled in his heart and asked, “Where is your second brother?”

Ma Jingyuan said: "My big brother because of HN business busy, the day before the return of HN the day before the HN back to HN."My brother is at home."

Ma Jingyuan thought about it and said, “Three children, I tell you, you want to be better to my sister in the future?”After this incident, my sister basically no one dared to kiss her, I can't see if I don't marry you, you will not be good to my sister, I will make you look good."

Zhu Hongsan knows some of the horse family's affairs, know that the horse Jing far away in the horse family's sense of existence is relatively low, did not expect to be so good to his half-sister, Zhu Hongsan asked: "Ma Lao San, your grandmother is not bad for you?"Why do you keep the little girl?”

Ma Jingyuan said: "You don't know, in our family only my sister is sincere to me, sincerely take me as a family, my aunt is indifferent to me, the eldest brother is too far away from home usually does not have much contact, the second brother is a child prodigy, on my surface, but I know that he basically I take me as a brother, perhaps than the family's servants."Only my sister secretly sent me buns at night when I was punished by my father for not eating.So you won't let you go if you're bad for your sister."

Ma Jingyuan said left, looking at Ma Jingyuan's back, Zhu Hongsan thought: "No one is really stupid, no matter who, as long as you are really good to him, you will have good returns."

Time has passed quickly, and it is a reverence for seven years.The great chaos in the world has become a foregone conclusion, and when Li Zicheng finally took the corner to pitch his uncle Gao Xiangxiang.It was also the year that Zhang Xianzhong, the murderous demon king, also started in Shaanxi, calling himself the eight kings.At the end of the Ming Dynasty, the two heavyweights of the peasant uprising finally entered the stage of history.

From Chongchen to the three years, there were more than 100 peasant armies throughout Shaanxi, and the peasant army has become a fire.At this time, due to the corruption and incompetence of the generals of the army, thousands of combat troops also joined the peasant army and became the backbone of thousands of combative border troops due to the lack of muzzles.

At this time, the peasant army is fighting, spontaneous and blind.The central government ordered the trilateral governor Yang He to adopt the strategy of "poking and giving, mainly caressing".But the central government was unable to feed a large number of hungry people, and they were already caressing and re-emerging.Yang He was in prison for this.

At this time, a powerful man appeared in Hong Chengyu, and Chongxuan ordered him to follow the supervision of Shaanxi to use the policy of "to caress, first to caress, then caressing", and to concentrate his forces on the Shaanxi peasant army.The peasant armies of various ministries successively advanced eastward, Chongchen for four to six years, and the movement of the activity center to Shaanxi was also extremely dispersed, and the development of each other's battles was relatively concentrated and echoed each other.Gao Yingxiang, Zhang Xianzhong, Li Zicheng, Luo Yucai and other departments of more than 200,000 people, known as the 36th battalion, once broke the city of Daning, Zezhou, Shouyang and so on.

Chongchen six years of winter, Gao Yingxiang and other 24 battalions of more than 100,000 people broke through the official army, transferred to the north of Yuxi Chu, officially entered the hinterland of the Central Plains, the general trend of the peasant uprising has been completed, not at all, three years and five years can be extinguished.After entering the Central Plains, the peasant army was centered on Qianyang, and the branches were interspersed between Yuchuchuan Shaanxi, using the weakness of the official army to guard the territory, and the weakness of non-coordinated, and carried out guerrilla-type mobile warfare.In order to change the passive situation of "unequivocal power and mutual observation", the central government has adopted the policy of "concentrating forces and comprehensively encircling and encircling".

Chongchen for seven years, with Chen Qiyu as the governor of the five provinces, unified command of Shaanxi Jin Yuchuan and Huguangguan army, from all sides into the attack, trying to destroy the various ministries of the peasant army.The peasant army successively turned into Han, and the encirclement fell short.Chongchen Zhu was removed by Chen Qiyu and succeeded the governor of five provinces with Hong Chengcao.When it moved the official army into Shaanxi and reorganized the siege, in addition to Li Zicheng still insisted on moving in Shaan Gan, other ministries again transferred to HN is now Chongchen seven years in June, what is our protagonist Zhu Hongsan doing?

Zhu Hongsan is 15 years old this year (the ancients are false years old), finally had the financial power in the previous year, and his mother Zhao Chunhua has become more and more old in recent years.My mother is not very young, just 34 years old.But in the morning, the average life expectancy under the medical conditions reached 35 years old, and thirty-four were already old.Zhao Chunhua's energy in recent years is more and more insufficient, found that his son has grown up, and the family's financial rights have been given to his son.

Zhu Hongsan bought a farm outside the city with two hundred and two silver, five houses, and built five more.This will be Zhu Hongsan in the base camp.The iron bull's father has died last year, Zhu Hongsan bought the iron bull's blacksmith shop, and now the iron bull is to work for Zhu Hongsan, in the farm to make Zhu Hongsan design of weapons.

At this time, Zhu Hongsan has built a small steelmaking plant in the future, and in the future, Zhu Hongsan has proved that the use of charcoal and pig iron products can be made of steel, and the disadvantage is that it is difficult to grasp the proportion of materials, so every time what steel can be produced is completely by luck.

Zhu Hongsan decided to use a converter side blowing method for ironmaking, the use of converter side blowing method, to add a certain proportion of cooked iron.The proportion is about 75% of pig iron, 25% of cooked iron, in addition to the need for a very small amount of sand and baking soda, because China's iron ore is sulphur ore, so the steel is brittle, the role of sand is to cause acid slag, sucking away the phosphorus contained in the iron, the role of baking soda is to deulfurize.

After Zhu Hongsan found diatomaceous soil, it was burned to make refractory bricks.And built a chemical iron furnace in the farm, this round molten iron furnace is not large, but much more complex than the converter.Because the converter requires that the iron water coming out of the chemical iron furnace must reach 1380 degrees Celsius.This temperature is difficult to match the general fuel, and the maximum temperature that can be achieved by humans is 1250 degrees Celsius before there is no heat storage room.

In order to reach this temperature, it is necessary to replace the cold drum wind with a hot drum wind.This is called a “heat room.”The concept of hot blows was invented by the Englishman Nelson, and was applied to the iron factory in Glasgow in 1829.

Zhu Hongsan's technical level of heat storage chamber is roughly the same as that of the British steel mill in 1850, using a cast iron tube hot air furnace.The cold drum wind passes from the duct tube to each heating furnace, and enters the tube on the other side of the heat exchanger through the arched cast iron pipe located on the fire, and then enters the vent of the iron furnace.

The whole set is sealed in a thick arched heating furnace with bricks and refractory materials to save and reflect the heat as much as possible, and after the blower is directly heated, the temperature can rise to 300 degrees Celsius, enough to melt lead.In addition, another measure is exhaust gas heating, from the top of the iron furnace with ceramic pipe will be introduced out of the iron furnace exhaust gas, from the upper part into the heat storage furnace, and then from the bottom of the exhaust gas.

There is no heat storage furnace, but also iron or steelmaking, but in terms of production efficiency is completely incomparable.According to British calculations, the early heat storage furnace increased the air delivery to more than 300 degrees Celsius, and the production of fuel iron was also three times higher than that of cold blowers.

The steelmaking furnace is basically completed, and the next step is coking.Zhu Hongsan used charcoal in the early days, but coke is still the most ideal fuel.Steelmaking Zhu Hongsan knows how to do, after all, the previous metallurgical professional knowledge has not been lost, but the coking will not work, so Zhu Hongsan can only take a simple earth coking.

There are many methods of earth coking, the simplest is the accumulation of open-air method, 2 to 4 tons of coal piled on the ground into a semi-circular pile, the bottom diameter of 3 to 4 meters, covered with straw to catch fire, 4 to 5 days can become coking, the coke rate is only 50%, this method has been used in the era of large steelmaking, resulting in resource waste and environmental pollution is extremely serious.Now Zhu Hongsan is still responsible for what environmental issues, it is important to save small lives, and let's talk about the rest later.

After more than half a year of preparation and construction, finally, coke and pig iron are ready.Zhu Hongsan called the iron bull and some workers, he repeated several points and the people in each operation: First, the adjustment of the air volume must be uniformly adjusted, can not be large or small, secondly, the iron water can not be higher than the tuyere when it is poured into the furnace, otherwise it will be the tuyere, and finally the amount of iron water, each time can not exceed one-sixth of the furnace chamber, and require workers to make a good record, because in the absence of a thermometer, Zhu Hongsan has done a good job.

Two animal blowers began to operate at the same time, each with two cows as power, and two on the side as a complement.A chemical iron furnace for the wind, the temperature gradually increased to more than 1300 degrees, the pig iron ingot has been completely melted, at the same time the furnace preheating, according to the requirements, the entire converter to preheat to 1000 degrees Celsius, to reduce the iron water after the temperature loss.

Since there is no thermometer, Zhu Hongsan can only rely on experience to fight, at least before the master in the practice in the steel mill to judge the temperature through the fire, the iron water was poured into the furnace began to blow, the iron water in the high temperature hot wind under the urge to continue to heat up.

Zhu Hongsan stared closely at the fire tongue in the furnace, a single iron flower constantly bursting, the fire tongue is red and yellow, followed by yellow and white - white, and finally completely white to shine.This shows that the furnace temperature is constantly increasing.Blowing lasted for almost ten minutes, the star-shaped carbon flower density continues to increase, the white tongue of fire from short to long, at this time the carbon combustion into the peak.

Zhu Hongsan saw that the tongue of fire began to become shorter, and the carbon flower was sparse, and he knew that the remaining carbon in the iron water began to approach the content of steel.He used the rocking rod to rise and fall up and down a time or twice to see if there were any more carbon flowers popping out, and when he saw that the carbon flower did not suddenly increase, he ordered the wind to be turned off.

Subsequently, the workers removed the roof and the duct, began to slag and slag, and finally poured.The sand is 90% yellow sand, 5% clay and 5% white mud.After the casting is made, it is a steel ingot.As for this steel ingot is high carbon, medium carbon and low carbon, it can not be controlled now, and it must be judged by the professional blacksmith after cooling.

The first furnace out of about 30 tons of steel, which is the minimum amount of material, according to Zhu Hongsanjian's blast furnace can produce up to 260 tons of steel.After cooling just now, the iron bull looked at it and tapped it with a hammer, and ran over and said, “Brother, this pot is all steel.”

The workers around him were surprised, and for more than half a year, he thought that it was just this white young master who had lost the family's money.Steel is all made out of a hundred, never heard of it can be directly trained with the stove.

Zhu Hongsan nodded and said to the forekeeper old Liu: "Uncle Liu, the process just recorded, especially the color of the fire, are all familiar with it?"

Old Liu's name is Liu Tiesheng, the family for generations are playing iron, the first time I heard that to build a steel furnace is ridiculous.But immediately after seeing the reality of the change of attitude towards Zhu Hongsan, even holding the disciple's courtesy, he felt that this must be a little public secret, and now taught me, then I am his disciple, old Liu respectfully said: "Master, the disciple remembers."

Zhu Hongsan did not care about the psychological changes of old Liu, and there were many surprising things in the future, where did this go?Zhu Hong nodded three times and said, "Well, you first practice two furnaces, and use the minimum amount of feeding."

Look at old Liu leading people to experiment without mentioning.Look at the steel ingots you practice, look at the level of medium-carbon steel, that is, the level of strip steel in the future.But don't forget that it is the Ming Dynasty, and no one in China can take out so many steelmaking at once.But still less, a gun will be 300 pounds to 500 pounds of steel.It seems that the current steel needs to be used in much needed areas.

The iron cow asked, “How about building your lock armor with this steel?”

The iron bull said, "Of course, a pair of locks weighs about 50 pounds, and you can achieve the same protective force with this kind of steel as long as 30 pounds."

Zhu Hongsan said: "Your lock armor I see the process is too cumbersome, there is time I improve your production process, let the output up."

The iron bull said, "Okay, this time there is steel, a lot of things can be built."

Zhu Hongsan stopped him and said, "Don't do the rest first, if you have time, you first hit 100 gunpowder cans, and you want the thinnest."

"Okay, I'll do it now."

I looked at myself and did nothing to need my own, and explained that old Liu should pay attention to safety, and at the same time, he explained that Zhao Tie egg did a good job of security, and Zhu Hongsan rode back to the city.In order to make iron furnace has not been home for half a month, I don't know what kind of mother is in a hurry.

Coming to the city gate, Zhu Hongsan saw a shantytown, inside are from Henan hungry people, because Li Zicheng, Henan has been destroyed in the shape, a large number of hungry people across the Yangtze River to the lake, Wuchang County, this is still very small, there are more than 10,000 people, the capital of the city is nearly 50,000 people.

Every day, people die, and the county organizes people to carry the dead out every day, and some of the dead have obvious traces of knife cutting, which is the beginning of someone eating human flesh.I have heard that children are lost every day in the exiles.Seeing this, Zhu Hongsan thought that he should start to form a team, the children in the exiles are a good choice, after a long journey of the body is not bad, the child is still brainwashing, good, go home to do a plan.
