Baoshan Iron and Steel Plant. Pen % fun % Pavilion www.biquge.info

On the wharf near the sea, iron ore has been piled into a small mountain, all of which are transported from the Daqingshan mine, and cargo ships arrive here every day, ranging from dozens of tons to hundreds of tons of iron ore.

On the wharf, in addition to iron ore, there is also a lot of high-quality coal, some of these coals are already burning coke, although it cannot be compared with modern coke refining, but the first batch of coke has come out and can be used.

With Zhang Feng here, refining coke is not a problem, even if the conditions are a little worse and there is no relevant industrial equipment, but Zhang Feng knows how to make coke by soil method, and the coke smelted can be used in Zhang Feng's view, and there is no problem with making iron.

Near the wharf, is a huge factory, several zhang high smelting furnace has been completed, this is a pig iron smelting furnace, of course, Zhang Feng designed and guided the construction, it took a lot of time.

This is the world's first steel plant, with an estimated annual output of tens of thousands of tons, and if it is expanded in the future, it is possible to produce tens of thousands of tons per year, or even more than 100,000 tons.

Of course, this can't be compared with modern large-scale iron and steel enterprises, modern iron and steel enterprises have an annual output of hundreds of thousands of tons, millions of tons, or even millions of tons.

But even at the workshop level, this is undoubtedly the world's first steel plant, with an annual output of tens of thousands of tons.

Today is the day of opening the furnace and making steel.

Early in the morning, the sun in the east has just shown a little bit, and under the morning sun, many workers have begun to get busy.

In the iron-making blast furnace, coke is being filled, ore is being filled, and next to the manpower blower next to the blast furnace, several workers are already in place......

An hour later, everything was ready.

Zhang Feng and Yang Shenghai came to the steel plant early, the two were not far from the blast furnace, and saw that the furnace was about to be opened to make iron, whether it was Yang Shenghai or Zhang Feng, both of them had joy on their faces, and Zhao Zuolin stood behind them.

Zhao Zuolin stretched his neck, took a look here, took a look there, his face was full of excitement, Zhao Zuolin came to the steel plant for the first time, saw all this, and thought excitedly, now it's okay, there will be enough steel in the future.

Thinking of the kind of steel described by Zhang Feng, Zhao Zuolin was very looking forward to it, if it was really as Zhang Feng said, there was really such a good quality of steel, then ......

Zhao Zuolin was even a little excited and didn't dare to think about it, because Zhang Feng said that the refined steel is not only of good quality, but also has a large output, and it is not a problem to refine tens of thousands of catties every day.

Tens of thousands of catties a day!

Oh my God!

Zhao Zuolin also wanted to be more and more excited, and even couldn't help but look at Zhang Feng again and again, in his eyes, in addition to excitement, there was obviously a bit of admiration.

Zhang Yue was born in a craftsman, his ancestors were still iron-making, and he was also proficient in steelmaking, Zhang Yue himself was good at frying steel, and Jiang Yue was now the manager of Baoshan Iron and Steel Plant.

I saw Zhang Yue walking over quickly all the way and reported loudly: "Boss, everything is ready, you can open the furnace to make steel." ”

Hearing this, Zhang Feng was very happy, worked hard, put in so much effort, and waited for this moment, Zhang Feng waved his hand and said loudly: "Ignition, open the furnace to make steel!" ”

The iron-making furnace soon made a fire, and several workers worked hard to supply air to the blast furnace, which was a manpower blower, and as everyone worked hard to blow the air, the flame in the blast furnace became vigorous, and the temperature became higher and higher, gradually turning from fire red to blazing white.

At high temperatures, iron ore begins to undergo a reduction reaction, turning from ore to molten iron, Zhang Feng is a big expert, several times to the blast furnace next to the side, through the observation hole to see the situation in the blast furnace.

Time passed minute by minute, and the huge furnace of the blast furnace was full of molten iron, and Zhang Yue came over again to report: "Boss, you can produce molten iron." ”

Pig iron smelting is not complicated, and the progress is relatively smooth, Zhang Feng waved his hand and said: "Open the furnace, produce molten iron!" ”

"Open the furnace! Molten iron !! ”

Jiang Yue shouted loudly, and not long after, the blazing white molten iron flowed out of the blast furnace and flowed along the refractory groove to the steelmaking furnace in the distance. As the molten iron flowed out, Zhang Feng and others felt the heat wave rolling.

Ironmaking is relatively simple, steelmaking is the key!

The modern steelmaking method first started in 1856 when the Englishman H. Bessemer invented the acid bottom blowing converter steelmaking method, which solved the problem of large-scale production of liquid steel for the first time and laid the foundation of modern steelmaking technology.

Zhang Feng also uses this steelmaking process, of course, Zhang Feng has more advanced steelmaking methods in mind, but limited by conditions, for the time being, can only use acid bottom blowing converter steelmaking method.

The advantages of this steelmaking method are obvious, first of all, the direct interaction between air and molten iron, so this steelmaking method has a very fast smelting speed, which is also the main reason why it can become the main steelmaking method at that time.

However, the acidic lining used in the Bessemer process cannot produce alkaline slag, so dephosphorization and desulfurization cannot be carried out. It was not until 1879 that the Englishman S.G. Thomas invented the alkaline air bottom blowing converter steelmaking method, which successfully solved the problem of smelting high-phosphorus pig iron.

Zhang Feng's plan is to use the acid bottom blowing converter steelmaking method first, and then use the more advanced alkaline air bottom blowing converter steelmaking method when there are conditions in the future.

After the molten iron entered the converter, Zhang Feng began to personally command everyone to make steel, although Zhang Feng had previously given everyone a certain amount of training, but the training was training, this time it was a real steelmaking.

Jiang Yue has a certain foundation and experience in steelmaking, but the acidic bottom blowing converter steelmaking method is also the first contact, Jiang Yue does not dare to take it lightly, and regardless of the high temperature, he almost rushes to the front line.

"Boss, the molten iron has become molten steel, and the molten steel can be produced."

After everyone's efforts, the molten iron is basically smelted into molten steel, and the molten iron is smelted into molten steel, and the most important thing is to reduce the carbon content in the molten iron.

After Zhang Feng looked through the observation hole, he said slowly: "Wait a while, continue to blow air into it to further reduce the carbon content." ”

In this era, there is no testing equipment, everything is based on experience, with his own eyes, Zhang Feng knows that the carbon content is absolutely more than 2% by observing the situation of molten steel, according to the standards of this era, it can be regarded as the standard of fine iron.

Continuing to smelt, Zhang Feng looked at the fineness of the molten steel again and said, "It's okay, start producing molten steel!" ”

Jiang Yue secretly remembered the fineness of the molten steel in his heart, knowing that this was the standard of steelmaking, and at least to this extent, he would open the furnace and release the molten steel.

When the molten steel came out, several workers were busy pouring the molten steel, and Zhang Feng was no longer used to guide him in this regard, just Jiang Yue.

This furnace of molten steel is thousands of catties, Zhao Zuolin's eyes have lit up, and he can't wait for these steel ingots to cool down immediately, so that he can take a good look.

Finally, when the steel ingots smelted in the first furnace basically cooled down, Zhao Zuolin was the first to rush up, looking at a piece of steel ingots with obvious residual heat, and his face was excited.

Although Zhao Zuolin doesn't know how to make steel, he has been talking to all kinds of stainless iron and steel all his life, and he can see at a glance that this steel ingot is definitely of the steel level, which is better than the steel he treasured before.

"Old... Boss, this... This is the steel we make! ”

Zhao Zuolin was excited because he was happy, and his tone trembled a little.

Zhang Feng smiled happily, also looked at the ingot, and said happily: "That's right, this is the steel we have made, and in the future, we will have a large amount of this steel." ”

A large amount of this steel.

Zhao Zuolin looked at the steel ingots, steel rods, and steel plates all over the ground, his eyes lit up, and one furnace was thousands of catties, which was enough to refine several furnaces a day.

Several furnaces a day, tens of thousands of catties a day, this... This....

Zhao Zuolin found that his head couldn't turn a little, and happiness came too suddenly! In the past, I was still worried about not having enough iron, so that the arsenal was discontinued, but now, it is not only enough, but it is all stainless steel.

"Boss, great, our arsenal will be ready to work again."

Zhang Feng said with a smile: "Lao Zhao, you will be busy in the future, we will build machine tools and steam engines." ”

Zhao Zuolin said happily: "No problem!" ”

Yang Shenghai was also happy, looking at this furnace is thousands of catties of steel, Yang Shenghai seems to see the silver of white flowers.

In this era, iron is not cheap, and profits are even more high, and like Baoshan Iron and Steel, with advanced smelting technology, it is even more profitable.
