"My lord, I'm not mistaken, right? More than 20,000 catties of pig iron, if you want to smelt so much iron, even if it is the largest furnace in the world, you have to refine it for three days and three nights, but it is only half a day here, this ........ , this ......" Gao Yan's voice trembled with obvious tremors. Pen, fun, pavilion www. biquge。 info

Lin Ze on the side smiled when he heard this.

He knew very well in his heart that Gao Yan was shocked in their hearts, but this matter was a trivial matter that was not worth making a fuss about for Lin Ze, or rather, for any modern person.

Lin Ze built a 15-cubic-meter blast furnace this time, and such a blast furnace can smelt 45 tons of iron per day even if it is calculated with a lower utilization factor, such as 3.

More than 20,000 catties of pig iron ingots, that is, the output of about ten tons, this output is less than one-third of the daily output!

The amount of pig iron was enough, Shen Lian closed the trench for casting with a surprised expression, and then opened the trench leading to the iron furnace, and the molten iron flowed smoothly into the iron furnace, which had been burning for more than an hour or so.

The reflex iron oven looks like a gongfu tea cup, but the bottom and walls of the cup are hollow, so that the molten iron is filled inside the cup, and the fuel such as charcoal is burned at the bottom of the cup.

Then, the flame produced by the combustion of charcoal fuel reflects the heat into the cup through the arched teacup, and then heats the molten iron inside, and the molten iron in the cup is continuously discharged under the high temperature burning, and finally, these impurities are turned into smoke and extracted from the chimney.

The chimney is buried directly under the trench where the molten iron flows in, which can play a good role in preheating the molten iron, and the next section is entangled with the intake air duct to heat up the fresh air sent by the blower, and finally exhaust the flue gas with reduced temperature into the air.

The molten iron in the furnace is heated by preheating the molten iron on the groove of the furnace to heat the air blown into the combustion chamber at the bottom, and the flame exerts residual heat all the way before finally dissipating into a wisp of smoke in the air.

Lin Ze has done such a detailed job in smoke exhaust, in fact, in order to save energy and reduce emissions.

Huangsha Town is originally a semi-desert area, such an ecological environment is extremely fragile, if it is not good, it is easy to turn this place into a real uninhabited area, Lin Ze wants to use Huangsha Town as his own base to develop, where will he destroy the ecology of Huangsha Town, it is too late to protect.

Therefore, Lin Ze directly gave his ironworks the best environmental protection measures that can be done now, in order to reduce the exhaust gas emitted by the ironworks and protect the environment around Huangsha Town.

In addition, this will also serve as a model for future ironworks.

With this iron-making plant, Lin Ze's iron-making plant will definitely adopt the same design in the future, so that the damage to the environment of the Shenzhou Continent will be reduced a lot in the future!

The aura on the Shenzhou Continent is indeed sufficient, and the growth rate of plants is many times stronger than that of the earth, but if for this reason, the unscrupulous destruction and pollution of the environment on the Shenzhou Continent will not be seen in the near future, and the Shenzhou Continent will also become a Chinese in the near future.

Protecting the environment is everyone's responsibility!

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

Lin Ze's design directly isolates the fuel and molten iron completely, so that once Lin Ze finds a coal mine in the future, he can use coal with confidence, and there is no need to do anything with the coal, just dig it out and use it directly.

Anyway, because of Lin Ze's design, coal is no longer in direct contact with iron, so some harmful substances such as sulfur and phosphorus contained in coal will not be mixed into molten iron.

Coal is much less expensive than charcoal, which needs to be fired in kilns, so it will be the fuel of choice when the ironworks are expanded in the future.

At this time, because the molten iron has been heated again, the surface has begun to glow with sparkling light - it is a fine slag mixed with the molten iron.

Seeing this, the experienced Gao Yan took a deep breath and directly started the mixing equipment with his right hand.

"Click, .......!" a start-up sound sounded, and a large disc mounted on the top of the iron-making furnace began to slowly rotate, and at the same time drove the three wrought-iron rods under the disc to move continuously.

Soon, the three wrought iron rods were stirring in circles in the molten iron, and the speed was kept very steady.

Seeing this, Gao Yan and Shen Lian looked at Lin Ze again, their eyes full of admiration.

Not to mention the new steelmaking method that Lin Ze came up with, which had never appeared before, just the direct use of water power was so superb, which made Shen Lian and Gao Yan and other senior craftsmen admire it in their hearts!

They never imagined that water, which is just very common, would have such a great effect and be able to provide such great power.

After formally seeing the role of hydraulic power, Shen Lian and Gao Yan began to vigorously develop the role of hydraulic power, and in the near future, they really developed a lot of hydraulic uses, and their names have left an extremely strong mark in history.

Of course, this is already hundreds of years later.

The current Gao Yan and Shen Lian have not even reached the entry level of hydraulic power!

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

The molten pig iron just smelted from the blast furnace has a carbon content of about three percent, and once stirred, the remaining carbon in the molten iron directly reacts violently with the oxygen in the air at high temperatures, and then, a large amount of carbon dioxide is produced, and at the same time, a large amount of heat is released.

"Gooooo........oo

The melting point of pig iron is about 1100-1200 degrees Celsius, while the melting point of pure iron is as high as 1535 degrees.

When the remaining carbon in the pig iron is combined with the oxygen in the air, the carbon content in the molten iron is of course gradually reduced, and correspondingly, its melting point is gradually increased, so the molten iron in the iron oven begins to gradually become thicker, from the clear soup to the sauce, and then from the sauce to the jelly...... In the end, they gathered into a very cute iron ball, which has a jelly-like appearance that children like to eat.

These iron balls look a little beautiful, but they don't know that they are about to be 'beaten'.

After seeing the gelatinous molten iron mass appear in the iron furnace, Shen Lian stopped stirring directly with great skill, and then, while the workers who had been waiting for a long time, used special long pliers to pick up the gelatinous molten iron mass in the iron furnace, put it under the forging hammer, and finally, beat it.

A sound of 'Ding Ding Dang .........' sounded, and the remaining carbon elements in the colloidal molten iron mass were directly squeezed out in the form of elemental graphite by the powerful force, and together with some fine dregs inside the molten iron and iron oxide chips on the surface, because of the high temperature, they turned into a little spark in the air, which looked beautiful!

This forging is only to remove the remaining impurities in the molten iron mass, the process is actually very simple, just use pliers to clamp it and beat it casually under the forging hammer, there are no special requirements.

Because wrought iron is very soft in high temperatures, it is easy to shape, and over time, the apprentices have works of all shapes, discus, iron rods, iron balls......

"Jingle ........!" The sound is endless, if these sounds are ordinary, they will only feel very harsh when they hear them, and they will even curse a few words directly, but now these voices are not harsh for Lin Ze, Wang Ming, Qiu Kai, etc., but they feel that these sounds are very 'beautiful'!

"It's so beautiful!" Wang Ming looked at the red iron in front of him, and his mouth kept admiring.

"Yes, it's really a beautiful view!" Qiu Kai agreed, his eyes staring straight at the red iron in front of him, as if this piece of iron was more seductive than a beautiful woman.

"Yes, it's indeed beautiful!" Lin Ze responded.

With this steel, Lin Ze's strength has increased a lot again.

Unlike Lin Ze, who only had steel in their eyes, Shen Lian and Gao Yan on the side only had the hammer that was constantly waving in their eyes.

You must know that when Gao Yan and Shen Lian were refining their iron before, the process of forging wrought iron was the most labor-intensive.

Dozens of catties of iron require strength to clamp up, and it is also necessary to master the time.

Wrought iron is very soft and relatively easy to beat, but after a long time, after the temperature goes down, wrought iron becomes extremely hard, and at this time, it cannot be beaten at all.

Therefore, Shen Lian and Gao Yan were really fortunate to make iron before.

Well, now, with the help of the hydraulic forging hammer, Gao Yan and Shen Lian have saved too much effort, and the quality of wrought iron hammered by the hydraulic forging hammer is much better than that hammered by Shen Lian before.

Therefore, Shen Lian and Gao Yan's eyes were all the shadows of the water conservancy forging hammer.

For these craftsmen, the hydraulic hammer is the best thing!

There are a lot of wrought iron smelted this time, there are hundreds of pieces, but Shen Lian and Gao Yan also have a lot of apprentices, the number is four or five hundred, Lin Ze is preparing for the expansion of the ironworks or the construction of another ironworks in the future, four or five hundred apprentices, each of them can't get a piece, and finally they have to line up for the hydraulic forging hammer, and the apprentices who can't grab it will directly tiptoe and stretch their necks to look behind............
