The blast furnace of steelmaking is a double furnace, with a preheated fire channel, using the best Fuxin sulfur-free coke, and the cyan flame makes a hissing sound, and there are bursts of blazing heat from far away, which discourages Lu Hanqiang and others who have no protective clothing.
Wearing a heavy heat-insulating cotton jacket, Master Li Er, the head craftsman, began to follow the method given by Lu Hanqiang, personally went into battle, and began to operate meticulously.
The two-layer refractory brick furnace is neatly stacked into a Zeng character, the upper layer is charcoal, and the lower layer is iron.
Block the fire door with a large piece of wood to start the fire, pull the bellows, and let the flames pour upside down from the upper layer of the Zengzi furnace to the lower level.
"Two-thirds charcoal, one-third coke, poured fire from the fire hole, saw the pig iron yellow, provoked the pig iron, and roasted it close to the flame," the high-paid hired master of the Ministry of Engineering muttered the iron frying outline given to him by Lu Hanqiang, and turned the iron seriously, sweat and oil rolled down his black and white face, soaking through the scorched robe.
Lu Hanqiang, who was standing on the side and pretending to be a ghost, tightened his heart, and his eyes were firmly fixed on the pig iron, for fear that his image of being worshiped by craftsmen would collapse.
Once you remember the mistake, it's not a shame, it's simply a shame.
Master Li Er's meticulous operation of the procedure, this is the iron frying technique taught to him by the Supervisor, according to the Supervisor, a good master can fry 80 catties of wrought iron from 100 catties of pig iron, and can even directly fry iron into steel.
At present, his own iron factory obviously has not yet met this requirement, and all the Mongolian Tartar helper blacksmiths are counted together, and there are less than ten craftsmen who can fry 70 catties of qualified wrought iron from 100 catties of pig iron.
It is not far from the beginning of spring, countless soldiers need stainless steel weapons and equipment, one day earlier out of stainless steel, one day earlier to kill the Tartars, when the Jiannu entered Kou Jinggi, he was also looted and burned by the Tartars in the Tongzhou Field Iron Works, his wife died under the sword of Jiannu, the children were taken away without the whereabouts of life and death, think about it and let yourself be heartbroken, if it were not for the Inspector promised to avenge himself, he would not have come to the north of this icy and snowy land.
Revenge is the wish of these dozen brothers with the same fate that he brought.
Under the blazing flame, the pig iron slowly turned white, and several Mongolian slaves pulled the bellows together, and the blue-white flame pierced more than three inches long, baking the iron to a direct glaze.
The master picked out the iron with tongs, looked at it carefully, and handed him over to the craftsman next to him.
The shirtless blacksmith had been waiting for a long time, took the iron, and beat the wrought iron into thin strips while it was hot on the stones by the mountain stream.
The brothers in charge of the next process collect wrought iron bars and cross-code them in the steel furnace.
A layer of iron bars and a layer of charcoal, after the steel furnace is full, the furnace is sealed, and the steel can be calcined with coke fire for seven days and seven nights. can forge countless broadswords and spears, which can be used by soldiers to go into battle to kill Jiannu.
"Ninety-nine in my hand, kill all Hu Er before I stop, I am a good son of the Han family, and I don't make horses and cattle for Tartar", Li Er, the master in charge of the calcination, whispered the military song of the Liao Army, and the sledgehammer and the small hammer jingled to accompany him.
The steel is of different colors, thick and hard, beaten into strips of quenching, and will be rotary welded as a blade.
If it is soft and tough, it will be quenched first, and then tempered and kneaded, which can be a crossbow arm.
This is what the Inspector said in his book, and it is definitely not bad.
Blacksmith Li Er grabbed the tip of the gun that had just been beaten, touched the tip of the hot gun, nodded with satisfaction, and put the head of the gun into the cold water.
A puff of white smoke rose from the pool, and after the smoke cleared, the blacksmith Li Er found that the overseer had quietly come over again, and stretched his neck to look here, his expression seemed to be more nervous than his own.
After testing the blade of the spear, he swiped lightly on his fingers, and a drop of bright red blood fell with the wind blade, and the heart of the blacksmith Li Er accelerated suddenly, and stabbed a stone with the head of the spear, sparks splashed everywhere, and the head of the spear was intact.
He raised his head suddenly, and said in a trembling voice to the overseer who was full of worry: "My lord is done, it is done, this is steel, this is really steel."
Then Li Er actually lay on the ground and whimpered and cried.
He cried because he had created a history that no longer had to be tempered and steeled, and he saw the hope of avenging his wife and daughter.
Lu Hanqiang trembled and picked up the head of the spear that was dropped on the ground by Li Er, and stroked it gently, "I succeeded, I really succeeded, God really favored me, let me really practice steel just by reading an idle book, from now on, my Fuliao army, my Ming army will be invincible in the world." ” Turning to the several documents following behind him, he commanded loudly: "Hurry up and write a letter to Lu Xiangsheng of the Ministry of War, hurry up and write a letter to Hong Chengchou in Shaanxi, hurry up and write a letter to Sun Yuanhua in Shandong, write a letter to the Ministry of Industry, hurry up and write a letter to the emperor Long live, tell them about our achievements, tell them that from now on, our Ming Dynasty will have a steel production of 100,000 or even 100,000,000 stones every year, and at that time, the world will tremble in front of our massive amount of steel."
Then he grabbed the clerk who turned around and ran: "Of course, we have to solemnly tell them that we are collecting money." ” As all the paperwork behind Lu Hanqiang was trembling, they were not trembling in fear because of what Lu Hanqiang said, but excited because of this huge achievement.
If in the near future, all the soldiers of the Ming Dynasty can wield stainless steel weapons to kill the battlefield, for the enemy's swords are cut in two, then what kind of situation will the battlefield be that is slaughter, the slaughter of the enemy.
At that time, there will still be such an embarrassing thing as killing a sacrificial ox on the expedition to kill a sacrificial ox on the expedition, and finally having to take out the Shang Fang sword without dying, will there be an embarrassing thing like a dignified general wearing a rotten helmet and being unjustly killed by a stray arrow Looking at those excited, rolling and crawling paperwork running back to his camp to write letters from all over the country, Lu Hanqiang took Li Er's hand and said apologetically: "Master, I'm sorry, this technology is related to the technical advantages of the dynasty within ten years, so I have to wronged you to take your apprentice within ten years, and you can't take another step within the sphere of influence of my army, but as compensation, I will give you a great wealth, and I will also send you hundreds of excellent disciples to be your apprentices, I will write this steelmaking method in your name, and his name is Lee's steelmaking method. ” For house arrest, Master Li Er didn't think much about himself at all, because in his opinion, in the era when craftsmen were not as humble as prostitutes, it was normal to keep a secret, but when he heard that this steel fried method would be recorded in his name and was named Li's steel frying method, he trembled with excitement t1706231537:
