On April 2nd, after breakfast, Xiao Zhenlei and others visited Duzla Company under the arrangement of Karloise, this company is very enthusiastic about the guests from the East to visit, after all, if you want Xiao Zhenlei and others to pay money, you must make them satisfied, so it is very good in the hospitality, Duzla Company specially sent a deputy manager to accompany the whole process, and Kaloise never left for a moment.

Among Xiao Zhenlei and other people, only Williams is an expert in the field of metallurgical industry, and the others are all laymen, so the selection of equipment mainly depends on Williams's opinion, Xiao Zhenlei handed over the purchase of steelmaking furnaces to him, a principle is to ensure the quality of the purchased steelmaking furnaces, and first purchase a small steelmaking furnace and two large and medium-sized steelmaking furnaces in terms of quantity.

On the way to Duzra, Williams popularized the advantages and characteristics of the open-hearth steelmaking method to Xiao Zhenlei and others, saying: "First, open-hearth steelmaking can use a large amount of scrap steel, and the ratio of pig iron to scrap is relatively flexible; Second, the requirements for the composition of molten iron in open-hearth steelmaking are not as strict as those for converters, and ordinary pig iron that cannot be used in converters can be used. I heard that your China Hanyang Iron Works first bought a converter, and after buying it back, there was a problem with the quality of the steel smelted because the composition of the iron ore did not meet the requirements, and it was not until you bought a new converter that this problem was solved! ”

Xiao Zhenlei couldn't help but be a little impressed by Williams, he didn't expect Williams to be so clear about the situation of Hanyang Iron Works, which is inconspicuous in the eyes of all countries in the world, it seems that Williams is very concerned about the situation of the steel industry in various countries, this is definitely a talent.

He nodded and said, "Yes, Williams, I can't imagine that you even know so well about the situation of our Chinese steel company!" ”

"No way, that's what I'm doing, of course, I have to have a detailed understanding of the metallurgical industry of various countries, and always pay attention to it! Let's not talk about this for now, let's continue the topic just now! ”

Williams continued: "Thirdly, there are more steel grades and better quality than converters in open-hearth steelmaking, and most countries currently use the alkaline open-hearth steelmaking method. As far as I know, you China built a 3-ton open-hearth furnace and a 15-ton acid open-hearth furnace in the Jiangnan Manufacturing Bureau 20 years ago, which should be the earliest steel-making open-hearth furnace in your country. According to the ratio of pig iron or molten iron and scrap in the steel material, different operation methods can be adopted, the first is the ore method, because the vast majority of the steel material is molten iron, in order to oxidize the impurities in the molten iron, a large amount of iron ore is added to the charge, the second is the scrap steel ore method, the pig iron accounts for more than half of the majority, and the scrap steel accounts for less than half, the appropriate amount of iron ore should be added, the third is the scrap steel method, the proportion of scrap steel in the material is large, in order to offset the carbon content, pig iron should be properly added, Generally between 30% and 40%, there is also a carbonization method, the vast majority of the material is scrap steel, the price of raw materials such as anthracite or petroleum coke when charging, from an economic point of view, there is a blast furnace to supply molten iron half of the steelmaking company with scrap ore method, if the price of scrap steel is low, you can use scrap steel! The process of open-hearth steelmaking is usually divided into these steps, such as furnace repair, charging, heating, mixing with molten iron, melting, refining, deoxidation and tapping. ”

Xiao Zhenlei was dizzy when he heard this, and said with a smile: "I can't imagine that there are so many doorways in this steelmaking, Mr. Williams, I don't know steelmaking, but this does not prevent me from wanting to open a steelmaking company, because you are here, you understand production management, technology, what you need, I will get you, I can solve everything for you other than steelmaking, and I will leave the matter of buying steelmaking furnaces and steelmaking to you!" ”

Williams nodded, "Thank you boss for your trust!" ”

After arriving at Duzla Company, the company's general manager, deputy general manager and factory director came out to greet them, and everyone had a long time to greet them, and then the senior management had something to leave, leaving a deputy general manager to accompany the whole visit.

After entering the factory, Xiao Zhenlei asked the other party: "Does your company have an open hearth in stock?" Can we go and see it? ”

The vice president said: "The steelmaking furnace is not a daily necessities, only the steelmaking company needs, so we usually do not produce and manufacture it and put it idle, only after the customer orders we will start manufacturing, but if you want to see the spot, we have a hearth furnace in use in the factory, now I can take you to see!" ”

"Okay, please take us to see it!" After Xiao Zhenlei finished speaking, the vice president of the other party nodded and led everyone to the steel mill.

Under the leadership of the vice president, everyone soon came to a production workshop, everyone was issued a certain safety production hat, this steelmaking workshop is very hot, everyone just came in and felt a heat wave coming, and when they got closer, they began to sweat.

The vice president of the company introduced: "Our company used to not make steel, only produce and manufacture steelmaking furnaces, because in recent years the international demand for steel has been increasing, our company has installed a steelmaking furnace, on the one hand to solve our own needs, on the other hand, we can sell the inexhaustible steel to the market!" ”

Xiao Zhenlei nodded and said that he understood, now that all countries are engaged in an arms race, a large number of artillery pieces are being built, and the shipyards of various countries have hardly stopped working, and some are divided into three shifts a day, and people are not stopping, so the need for steel is greater than ever.

Approaching the steelmaking open-hearth, the company's vice president introduced: "Our steel-making furnace is only 100 tons, can only be regarded as a medium-sized open-hearth, last year only started steelmaking, you see, this open-hearth furnace is mainly fueled by gas or heavy oil, of course, you can also use coal, but the temperature generated by gas or heavy oil is much higher." The main components of this open-hearth furnace are melting chamber, furnace head, rising channel, regenerator, reversing valve, flue, chimney, etc. You see this big belly is the smelting room, where the steelmaking raw materials are melted, here is the charging furnace door, the bottom of the back has a taphole, and there is a rifled flame furnace for steelmaking and heat distribution regenerator below! ”

Xiao Zhenlei and others visited the steelmaking furnace for half an hour under the high temperature, and after figuring out all the parts and their functions, they walked from the taphole to the back process under the leadership of the company's vice president.

After the molten steel flows out of the tap port of the steelmaking furnace, it flows into a long sink-like utensil, and flows down along the elongated sink-like apparatus, and at the back of this process, workers bring various abrasives to fill the molten steel and carry it away, and after the molten steel cools, it becomes a large steel block of different sizes or a rectangular steel bar, or becomes a long and thin steel bar and other building materials.

In the steelmaking production workshop, Xiao Zhenlei and others stayed for a morning, the Germans may have a high level of professionalism, not only not impatient, but also very enthusiastic to introduce various processes, people are not afraid of technology leakage, this kind of steelmaking production process and detailed process flow, most countries have, others are not rare at all, so they will open the door for Xiao Zhenlei and others to visit, and these things are not you can learn by staying here for a day, technology to practice to accumulate experience, And some techniques are invisible, if you want to keep it secret, people will keep a hand, if everyone can learn it by looking at it, I'm afraid that this technology is not worth anything, so they don't have any defense against Xiao Zhenlei and others.

At noon, the vice president of the company arranged for a big pot of rice in the canteen of the factory, although Su Gu and others were really not very interested in the bread and cream of foreigners, but they were so mindful that everyone would eat a meal.

In the company's vice president arranged a break for two hours in the lounge, two o'clock in the afternoon and continue to visit, this visit is the manufacture of other metallurgical machinery parts of the production process and process, there are several production workshops, each production workshop at the same time to produce several parts, workshop one side against the wall hung a large blackboard, the blackboard is written this month's production tasks, as well as the completion of the task every day.

For the arrival of Xiao Zhenlei and others, the German workers in each production workshop should not have seen it, they were doing their own things, and Xiao Zhenlei found that the German factory was very strict in the management of workers, and after each process came out, there were special personnel to carry out product quality inspection, and those who were unqualified could not enter the next process.

After the visit, everyone returned to the hotel at about five o'clock in the afternoon to rest, Xiao Zhenlei called Williams to his room to discuss, and both of them smoked.

Xiao Zhenlei asked, "Williams, what do you think of the strength of this company?" Can the steelmaking furnace be produced to meet our requirements? ”

Williams nodded and said: "It should be possible, I have done a survey before, even Krupp uses the steelmaking furnace produced by this company, when I visited the steelmaking workshop in the morning, I carefully observed the steelmaking furnace they made themselves, and thought that its quality is very good, if the quality of the steelmaking furnace we bought is comparable to that one, it will not be in vain!" ”

Xiao Zhenlei thought for a while and said: "Okay, I will be fully responsible for buying a steelmaking furnace, you will be fully responsible for buying a steelmaking furnace, you will do a market research in the past two days, what is the price of the current steelmaking furnace, whether the manufacturer can send someone to install and provide technical support, etc., you have to figure it out, let's not suffer in this regard, don't buy things back and can't use them when the time comes, and be tricked by others, this is going to be a joke, I don't want to be treated as a fool's joke, do you understand?" ”

Williams said strictly: "Boss, don't worry, I will be strict!" ”

On April 3, Xiao Zhenlei and others went to the Krupp steel smelter to visit, I have to say that the energy and face of Kaloise is still very large, at first Krupp did not agree with Xiao Zhenlei and others to visit, after all, the performance of Krupp cannons is better than the performance of some other cannons, a large part of the quality of the steel used in Krupp cannons, and these steel products for the production of Krupp cannons are produced by Krupp steel smelters. Krupp Steel Smelter has a unique metallurgical technology that no other steel plant has!

At the helm of this generation of the Krupp family was Gustav Krupp, who was a former diplomat of Kaiser Wilhelm II and had no blood relationship with the Krupp family, and Kaiser Wilhelm II arranged for him to marry the elder Krupp's granddaughter Bertha, join the Krupp family, and change his surname to Krupp, in order to run the business of this illustrious family and prevent it from falling into the hands of political enemies. Observing time, following discipline, and carrying out orders are the family's traditions. For example, breakfast is at 7:15 a.m., and those who arrive at 7:16 a.m. will find that the restaurant is closed and someone else has already started eating. In addition, even in the middle of winter, Gustav Krupp refused to turn on the fireplace, deliberately making the office cold so as not to become listless. I have to say that there is a certain reason why this family is famous all over the world.

Krupp is different from other companies, this is Xiao Zhenlei's first feeling when he walks into the Krupp steel smelter, why is it different, what is different, Xiao Zhenlei can't say, but he quickly understood.

Even in the steelmaking workshop and parts manufacturing workshop, which are most prone to garbage, are very clean, of course, except for the iron filings on the ground that are generated because the work is working, in addition to being clean and tidy, the work of the workers is in good order, no one is idle, no worker is at a loss, and the management of Krupp has brought the labor of the factory workers to the extreme, without the slightest waste.

Xiao Zhenlei and others were not allowed to enter the steelmaking workshop, because it contained the core secret of the Krupp company -- unique metallurgical technology, and any workers and managers who entered it had to go through strict inspection, and they could not bring anything in or out.

When it was almost noon, Xiao Zhenlei and others came out of the Krupp steel smelter with some unfinished business, not only Xiao Zhenlei felt that there was not enough time, but Williams was the same, he was engaged in this industry, so he wanted to visit it for a while more than Xiao Zhenlei.

On the way to the restaurant for lunch, Xiao Zhenlei asked, "Williams, you said that if I buy their metallurgical technology from Krupp, will they buy it for me?" ”

Williams almost couldn't help rolling his eyes when he heard this, he hit unceremoniously: "Boss, I have to say that your idea is too wildly fanciful and whimsical, even if William II wants to buy their metallurgical technology, they won't buy it, this is their family's top secret, it is the capital to survive, whoever wants to rob them of this technology, they will definitely fight with others!" ”

Xiao Zhenlei was a little embarrassed when he heard this, and shrugged his shoulders with a smile: "Forget it, I just said it casually, I wasn't stupid enough to think that they would really throw away their jobs for money!" ”R1152
