"Gao Yan, it's going well now, but don't be careless in the next thing! Iron smelting is not an easy thing, and if you are not careful, the danger is still very great. Pen "Fun" Pavilion www.biquge.info" Lin Ze told with a smile.

Iron smelting is not a simple matter, and if you are not careful, there will be problems in the middle.

When the time comes, not to mention the economic losses, even people may be killed or injured.

"Yes, my lord, I will not be careless in my humble position!" Gao Yan replied respectfully, his heart full of vigilance.

Gao Yan has been working in the ironmaking shop in Qingzhou for more than ten years, and he knows the danger of ironmaking, so he knows very well that now is the first step in the long march, and he is not careless at all.

"Well, that's good, let's go!" Lin Ze nodded with a smile, and then asked Gao Yan to go back to smelting iron.

"Yes, my lord!" Gao Yan agreed, turning and walking towards the iron-making furnace.

Just in front of the iron-making blast furnace, Gao Yan picked up the brightly colored flag on the side, directly waved the small flag in his hand, and then shouted loudly: "Start ironmaking!"

Shen Lian, who had been waiting next to him for a long time, saw Gao Yan give the order, and he immediately pulled down the machine.

"Whoa, ......whoa, whoa!" The huge waterwheel slowly rotates under the impact of the water, and the water in the drainage canal hits the water retaining sheet, transmitting the kinetic energy of the water force flowing down from the height to the waterwheel, and then the eccentric wheel turns the rotating motion of the waterwheel into the reciprocating motion of the bellows piston.

With the rotation of the wooden utensils .......... 'chirping', the fresh air outside is blown into the blast furnace by the bellows from the air duct.

".........Boom!" A violent flame ignited in the blast furnace, and then, the iron ore placed in the blast furnace began to gradually turn red and soften.........

At the beginning, the waterwheel rotated slowly, correspondingly, the wind pressure of the blower on the side of the blast furnace was small, which led to a lack of oxygen supply in the blast furnace, so at this time, from the chimney on the top of the blast furnace came out of the thick black smoke, which directly turned the originally blue sky into gray.

Then, as the waterwheel turned faster and faster, the speed of the blower was getting faster and faster, correspondingly, the supply of fresh oxygen to the blast furnace was more sufficient, and then, the smoke from the chimney above the blast furnace gradually turned from black to blue, and then from green to white, the color was getting lighter and lighter, and finally, with a 'boom....', a large orange-red flame rose happily from the top of the furnace, directly illuminating the sky a lot.

The fire in the blast furnace has now burned completely, and now the iron smelting has officially begun.

In the blast furnace, in addition to charcoal, the blast furnace is also filled with some iron ore that has been washed and calcined in the earth kiln, and limestone is used as a slag agent.

Gao Yan had already come to the feeding port at this time, this was the first time to make iron, and he had to do it himself, so seeing that the time for feeding had come, Gao Yan directly pulled the motor.

With a sound of "click, .......", the winch linked with the waterwheel began to rotate, and at this time, the rope that dragged the blast furnace feeding dump truck slowly tightened through the pulley block.

The .......dump truck climbed to the top of the blast furnace along the 30-degree inclined slide rail, and saw that the dump truck had reached the right position, and the person at the bottom pulled the control cable, and the ore in the 'click...... car was poured directly into the blast furnace.

After the iron ore had been completely poured into the blast furnace, the underground workers pulled the ropes on their hands again, and the dump truck slowly returned to its original state and retreated.

Next, the workers shoveled the charcoal into the dump truck again, and then, after it was full, it climbed to the top of the stove again......

Seeing that the underground workers had safely sent a large amount of iron ore and charcoal into the blast furnace so simply, Gao Yan and Shen Lian on the side were full of excitement, and they really admired Lin Ze in their hearts.

In the past, when iron-making, how to transport iron ore and charcoal was a dangerous thing.

Carrying hundreds of pounds of charcoal or iron ore, at a high temperature of thousands of degrees, on top of a blast furnace of more than ten meters, this kind of work is really a very dangerous job, and if it is not good, it will really lose your life.

Gao Yan and Shen Lian had seen this kind of thing a few times before.

That's why the hearts of the two of them were so excited after seeing the workers below send the iron ore and charcoal into the blast furnace so easily and safely.

.........................

Seeing that the iron ore and charcoal had entered the blast furnace and began to react violently, Gao Yan directly waved the colorful flag in his hand, and suddenly, a person ignited the charcoal in the preheating pool, and the air entering the furnace was preheated and blown into the furnace to intensify the combustion reaction.

"Boom, .........boom, boom!" Charcoal and iron ore met each other late, like newlywed men and women in the blazing blast furnace, the two of them embraced, rolled, and rubbed each other, and the 'love fire' released around them was extremely violent, and they actually rushed out of the chimney on the top of the blast furnace and went straight to the sky.

'Boom, boom......., boom' is tempting//people's high//tidal gasping//breathing wave after wave, constantly spreading.........

Everyone present stayed by the blast furnace in amazement, watching this strange scene that they had never seen before, even if it was a wise man like Wang Ming and Qiu Kai, after seeing the current scene, their faces were extremely surprised.

Wang Ming and Qiu Kai had never seen such a scene before.

Of course, among these people with surprised faces, there will be no Lin Ze.

The ironworks here are very 'huge' in the eyes of Wang Ming and Qiu Kai, but in Lin Ze's eyes, such ironworks are not even comparable to the ironworks in the smallest town on the earth, let alone those national-level ironworks.

Even if it is a national-level iron-making plant, Lin Ze has personally visited a few, and the iron-making plant that is so small that even the town-level ironworks cannot be compared, where will Lin Ze be shocked.

Therefore, when Shen Lian and Gao Yan were both stunned and looked at the blast furnace of iron-making excitedly, Lin Ze just looked at it for a while, and then he walked around.

The time required to make iron is not short, not to mention the current local method of ironmaking, if you want to smelt all the iron in this blast furnace, it will not take six or seven hours, and it is absolutely impossible.

Rather than wasting six or seven hours at the blast furnace, you should use that time to look around and see if there is anything that needs to be improved.

.....................

Time passed quickly, about an hour after lunch, Lin Ze saw Gao Yan stumbling towards him, and when Gao Yan ran in front of him, his face was swollen red, and the green tendons on his neck jumped.

"Big ........ My lord......... It's too fast!.......... , my lord, go and take a look, the blast furnace has been burned into molten iron!" Gao Yan ran in front of Lin Ze and said angrily.

"What, it's done now?" Lin Ze hadn't said anything, and Qiu Kai and Wang Ming on the side stood up in surprise and asked.

Qiu Kai and Wang Ming are not blacksmiths, but they also know that if a furnace of iron wants to be smelted, it will definitely take about seventeen or eighteen hours, but now it is only six hours, how can it be smelted?

If Wang Ming and Qiu Kai hadn't understood that Gao Yan didn't dare to deceive them, they would have thought that Gao Yan was joking with them.

Looking at the surprised expressions on Wang Ming and Qiu Kai's faces, Lin Ze smiled, and then said with a smile: "Wang Ming, Qiu Kai, be calm, stay calm, this is a very normal thing." ”

After saying this, Lin Ze's face was indifferent, as if this matter had been expected by him a long time ago.

If a modern person sees Lin Ze's appearance now, he will definitely say with disdain: "Pretending to be // forced, this kid is pretending to be // forced!"

Gao Yan didn't know that Lin Ze was pretending to be // forced now, when he was smelting iron before, the time was never less than seventeen or eighteen hours, but now it is only six hours, and the iron is smelted, where can Gao Yan not be excited in his heart?!

In the past, when he was smelting iron with those masters in Qingzhou, although the blast furnace at that time was not much smaller than the blast furnace established by Lin Ze now, and the iron produced at one time was also less, but the effort and charcoal spent were several times more, and it could not be compared in terms of time.

However, now, it is only six hours, not even half a day, and the iron ore has not been burned red before, but it has been smelted into molten iron here!

This......... This......... When Gao Yan saw this situation, he pinched his thigh directly a few times, and the severe pain made him understand that this was not a dream, it was true.

In fact, it is not surprising that Lian Te is so fast, this is all due to the preheating of the air.

You can imagine that when you eat hot pot in summer, if the air conditioner is blowing on the hot pot, will the hot pot not boil for a long time?

The same is true for ironmaking, the air at room temperature of 20 degrees Celsius blows into the blast furnace of thousands of degrees, which is tantamount to pouring ice water on the fire, and the charcoal in the furnace not only heats the iron ore, but also heats the air, which has just been heated and runs away from the top of the furnace, and the air duct blows in new cold air.

Poor Brother Charcoal, as if he played "Seven Stars with the Moon" and "Eight Stars Annunciation", and then he is a fierce man who is as strong as a bull in some aspects, he can't stand it like this!
