Siheyuan: Cooking journey

But for this emerging construction company,

He Yuzhu did not intend to personally participate or co-operate.

He drew the sketch, and the new steel plant on the outskirts of the city began to break ground. Thanks to the support of the stainless steel export business and instant noodle production, the funds were sufficient and there was no need to seek additional assistance. The construction of the new project still relied on the technical guidance of the Guo family and hired villagers from surrounding towns to do the work. The only difference was that there were more people wearing old-style uniforms.

This is just a minor change. After all, wearing uniforms and work clothes is a popular trend, and no one cares what they did before.

Winter passes and spring comes,

History has entered a new page.

The superiors finally issued an official announcement on the adjustment of the manufacturing industry, and the news caused an uproar as soon as it was disclosed. The first batch of enterprises to pilot the reform gradually expanded from the initial ten to thirty, one hundred... until it reached hundreds. This plan covers a wide range of content, but for the majority of the working class, the most concerned thing is the adjustment of the salary system.

Wages are no longer a fixed amount.

Hardworking people will certainly be happy to see such changes, because they earn more; while those who are used to being lazy are forced to accept lower basic pay. Under this irresistible trend, they have to adjust their attitude and be more serious.

In this way, with the various emotional fluctuations of different people

He Yuzhu learned the latest news.

The administrative level was promoted to deputy director level, with a monthly salary of 177 yuan. Although I don't care too much about the position or salary,

But he was still very happy to be on the same administrative level as the former factory director. After all, although Director Yang was a deputy, his administrative level had not changed much.

As a friend who has worked with me for many years,

He Yuzhu felt sorry for the other party, and at the same time, he was also worried about Director Yang's mood, so he immediately called to comfort him, "Don't be sad, Old Yang, you are only a little older than me, I believe you still have great potential for development in the future;

"We are at the same level now, maybe I will be promoted one day, haha;

"In terms of ability and looks, you can't compete with me, but you are older at least!"

"No matter when, you will always be the big brother in my heart!"

"Thinking this way, do you feel better?"

After hearing this, Director Yang was furious and said angrily:

"What do you mean much better? You are deliberately looking for trouble."

"Stop talking nonsense. I just happen to have something to talk to you about;"

"I was a little embarrassed to bother you, but now that you know how awesome you are, I won't be polite to you..."

It doesn't sound like anything good.

He Yuzhu quickly hung up the phone.

He still has a lot of messy things to deal with.

He didn't want to get involved in the steel plant's affairs at all.

It’s a good idea to think this way.

Unexpectedly, not long after, Director Yang actually came to the door in person and refused to leave.

He Yuzhu had no choice but to ask him what was going on.

"Last month, we went to Germany for a visit and inspection."

Director Yang sighed, looking worried:

"This time we went to see the coke ovens;"

"Do you know what a coke oven is? It's used to make coke, the kind used to make steel;"

"Our steel plant used to have two small coke ovens, which were built decades ago and could not produce much coke a year;"

“Over the years, demand has increased, and those old, small coke ovens can no longer keep up;”

“So now the plan is to build a large new coke oven.”

Director Yang explained it in great detail.

Even if He Yuzhu didn't want to listen, it was difficult.

Steel is a key material for industrial development.

And coke is the key among the keys, which directly determines the steel production...

In the early years, the technical level in this regard was not much different between China and Germany, but after years of changes and development, various factors have combined to make my country's technological progress relatively slow, while Germany has been at the forefront of the world and has the world's most advanced coke oven equipment and technology.

The purpose of visiting Germany is to introduce their best technology.

But the price they asked was too high and our foreign exchange funds were tight.

Therefore, after discussion, it was decided to develop and build coke ovens by ourselves. The existing coke ovens in the country can temporarily support the current demand, and also leave enough time for research work.

If it really doesn't work, let's talk about it later.

It was probably with this mentality that Director Yang took on the task of building the new coke oven at the steel plant.

There are many difficulties encountered here.

Apart from the refractory materials, the most difficult part is actually the manufacturing process.

Although my country has accumulated a certain amount of experience in the production of coke ovens and does have some information, it is very difficult to make further breakthroughs on the existing basis.

The main difficulty lies in the fact that different types of coke ovens have different characteristics and requirements.

There are two main types of coke ovens: top-loading coke ovens and ramming coke ovens.

These two types of coke ovens each have their own advantages.

Top-loading coke ovens are those where coal is added from above for high-temperature processing.

This structure is relatively simple to operate, but it requires the use of high-quality coal to ensure the quality of the final product.

The ramming coke oven uses a side loading method, where the coal is pressed into cakes before being fed into the oven for combustion.

The biggest advantage of this method is that it can utilize coal of various quality grades and turn inferior products into high-quality coke products through reasonable matching.

However, high-grade coal mines are rare in my country.

So in this case, it becomes particularly necessary to promote and develop ramming coke ovens.

We have tried to develop some examples of this type of technology in the past and have successfully put into operation a few cases, but the output was too low and there were many problems, so it cannot be compared with the cutting-edge level in Germany.

After visiting and studying there,

Our senior predecessors’ horizons were suddenly broadened a lot, and they were determined to produce something of the same high level.

Although they could not afford ready-made knowledge, they at least recorded the basic structure of the outside through repeated inspections; as for the more complex structural design inside, they had no idea at all.

In addition, many supporting mechanical equipment such as automatic coal feeders are not yet produced in China.

If we want to independently develop a set of top-notch ramming coke ovens, it means that the entire heavy industry sector will face an innovative challenge.

Facing such a thorny problem, not only Director Yang was troubled,

The major factories that were assigned specific development tasks also complained bitterly.

With only a rough memory and a few rough outline drawings at hand, we started working.

They were so anxious that several of their hairs turned white overnight. . .

Director Yang looked troubled.

He Yuzhu looked at his sparse hair and felt sympathetic. He asked:

"So what do you want me to do for you?"

"If it's about cooking, I can give you some advice. But as for coke ovens, I know nothing at all."

This is really not modesty.

Although I have read a lot of books and know a lot about science,

But He Yuzhu really doesn't know much about the coke production industry.

A good cook cannot cook without rice.

He had never seen relevant information and had no idea what a coke oven looked like, so naturally he didn't understand the ins and outs of it.

But to be honest, if we can do an on-site inspection and look at some design drawings, we should be able to get a rough idea of ​​the situation. But going to Germany is too far.

"I know you don't know this business."

Director Yang rubbed his hands and said with a smile:

"It doesn't matter, as long as you can find someone who understands."

"You've run the instant noodle factory successfully and even imported production lines. You must have acquaintances there."

"We don't ask for much, just the latest coke oven blueprints."

"I just want a most common coke oven design;"

"Compared with other countries' mature industrial systems, the tamping coke oven we developed is still a long way behind;"

“It’s much better to have a basic blueprint to refer to and then continue to research and develop; this is a great thing for us.”

"Some of the newest coke ovens in Germany can produce 600,000 tons per year. The old equipment that produces 100,000 or 200,000 tons per year is basically no longer in use. It shouldn't be difficult to get a design drawing like this."

After a brief pause,

Director Yang said with envy and some emotion:

“Only when you go there will you realize how big the gap is;”

"Our coke ovens are mainly used to produce coke for sale. The by-products are hardly used, except for some coal gas."

“But it’s different over there, they just use coking as a starting point;

"The processed coal tar can then be further refined into various chemicals;"

“Someone over there said that you can’t actually make much money just by selling coke, and the real profit comes from the income from these derivative products;

"I dare not even think about it. When will our country be able to catch up with others in this regard? "

"Of course, the most advanced coke ovens are out of the question for the time being."

"We are now planning to develop a new plant with an annual production capacity of 300,000 tons and develop related chemical technologies at the same time."

"If nothing else, the most important thing is to provide clean natural gas for the people to use, which will make life more convenient for many families."

It's just the most basic file that has been eliminated.

After thinking about it, this is not really a difficult task to accomplish;

With the help of the Guo family, he contacted his friends in Japan to find out;

Or it may be a good idea to just spend money to find an expert to give you guidance.

After all, there is no point in keeping backward technology secret.

And who can resist money?

"There is another way to get the best design directly from Japan;"

"You know, there are a lot of steel mills over there, and they must be equipped with many modern large furnaces;"

"We can't rely entirely on imported coke."

"Another piece of evidence is that one of the conditions proposed by Japan before included purchasing domestically produced coal resources at a low price."

"Some of this will definitely be used to make this high-efficiency energy conversion equipment;"

“I didn’t even notice this problem during my last visit;”

“Although it’s too troublesome to go to Germany, considering that we need to go to the neighboring country to promote instant noodles recently, it’s only natural to visit the factory site.”

After a little thought,

He Yuzhu agreed:

"If that's the case, I can try to contact some people and see. I guess it shouldn't be difficult according to what you mean."

"well!"

Director Yang was overjoyed;

Although he is the leader responsible for the advancement of the entire project,

But his main task is to coordinate and arrange various aspects.

As for specific production process problems, they have to rely on other specialized talents to solve them.
