Yao Chongshan is 28 years old, and in a few months, he will be able to get a doctorate from Bencheng University of Technology.

It stands to reason that getting a doctorate should be a joy for many people, especially in this year, having a doctorate is quite popular, and it is not a problem at all in terms of employment.

Especially for him who specializes in technology, he is still the most sought-after metal casting doctor in the market, and before he graduated, he participated in many large-scale projects with his supervisor, and also published several papers in some of the more famous magazines in China.

is also well-known in this industry, coupled with the recommendation given to him by his mentor, as long as he graduates and walks out of school in the future, it will not be a problem to find a job with an annual salary of more than 200,000 yuan.

This is just the price of some iron and steel enterprises in the north, Anshan Iron and Steel has someone to contact him, if you are willing to go to their side, then the annual salary is 200,000 yuan, and to give the house and the car, the annual salary increase in the future is easy to discuss.

On the other hand, Shougang in Beijing and Baosteel in Puhai also gave him conditions, and the conditions are better than the other, among which the best conditions are Baosteel, the boss of the wealthy domestic iron and steel enterprises.

The conditions given by the people are that the annual salary is 400,000 yuan, to apply for a Puhai household registration, and to provide a suite after working in Baosteel for five years, more than ten years, and the car is not a problem.

The most important thing is that people say that there is no cap on the annual salary, and the longer you work in the company, the higher the salary will be, which shows that the company is eager to find talents.

In the past two years, the domestic steel industry. With the continuous development of the country's economy, the scale is getting bigger and bigger. The pace of development is also getting faster and faster. But in terms of technology, it has been a little bit unstable.

Now these steel mills not only produce some low-end plates, pipes and other building profiles, because of their special state-owned enterprise background, they can often receive orders from some other large domestic enterprises.

For example, orders from large nuclear power companies, as well as orders from large domestic hydropower companies, as well as orders from the shipbuilding industry, etc., and the orders of these enterprises. There are often very strict standards for the requirements of profile pipe fittings.

Compared with the most common profiles on the market, there is a world of difference, such profiles, not only in the shape of the construction requirements, but also in the strength, and life requirements are not small.

This requires a very high casting process, as well as a lot of effort in metal alloys.

Such a profile is not very laborious to build, but once you can develop it, then the profit is also considerable, at least just get an order from a large nuclear power company, the profit can be created. It's far higher than the profit you make selling tens of thousands of tons of ordinary steel in the market.

Therefore, these domestic steel mills are very close to such orders. However, at present, we still do not pass the casting process and materials of some special profiles in China, so some orders can only be seen but not eaten.

But this does not prevent everyone from tackling this problem of determination, just recently the steel industry is still very prosperous, so we also have so much spare money, to reserve talents, or to invest in technology, it is really not good, just spend a lot of money from abroad to introduce technology.

But the key to everything is that you have to have your own qualified talents, so senior talents like Yao Chongshan immediately became the sweethearts of those large steel companies.

Understand technology, understand the process and process of the foundry industry, and also understand the metallurgical industry of special alloys, isn't this just the cutting-edge talents that those iron and steel enterprises urgently need?

So now Yao Chongshan is very popular in the talent market, he graduated with several doctorates in the same period, and they have basically signed contracts with several giants in the domestic steel industry early.

If nothing goes wrong, they will come to those enterprises, they will immediately be used as a technical backbone by the enterprise to focus on training, after five or six years or seven or eight years in the post, some of them in the same batch of people, some people may make achievements in the field of scientific research, and some people may take the leadership position, anyway, they are the kind with unlimited future.

If it had been a few months ago, Yao Chongshan might have chosen one of the steel companies without hesitation to sign the contract and sell himself.

But now he is not in a hurry, but wants to weigh more trade-offs, his thoughts like this, even his mentor, feel a little strange, this Xiaoyao, usually a very smart child, now what's going on? How can you be stupid when it comes to such an important juncture as employment?

In fact, all of this started a few months ago, when Yao Chongshan and his mentor went to the United States to participate in a technical exchange seminar.

At that time, Yao Chongshan followed his mentor to Los Angeles in the United States to participate in a new generation science and technology fair led by Lawrence Laboratory in the United States.

The Lawrence Laboratory, located in California, USA, is one of the national laboratories in the United States, although it is not as famous as the Oak Ridge Laboratory, but the origin of this laboratory is definitely not small, and he mainly specializes in metal smelting and manufacturing.

At this expo, it is actually just a large-scale product recommendation meeting, and the main technology promoted by Lawrence Lab this time is 3D printing technology that has quietly emerged a few years ago.

Yao Chongshan had also heard about this technology when he entered his own major before, but at that time, this technology had just emerged and was not very mature.

Even in the past two years, this technology has become more and more mature, but it is still questioned by many experts and scientists, believing that this technology is just a gimmick, and it is impossible to replace the traditional metalworking industry.

The reason is very simple, although this technology has its own unique advantages, but in the field of modern high-tech machinery, there are many parts that need to use special alloys, and this 3D printing technology is simply powerless for processing such special alloys.

So far, it is only able to process some, plastics, rubber, or ceramic powders and other products, not to mention special alloys, even ordinary metals, the current 3D printing technology, can not do anything.

With such a chicken rib technology, what else can we talk about, it can become the originator of the third industrial revolution.

So Yao Chongshan didn't attach much importance to this technology before, but this time he went to the United States to participate in the expo and watched the demonstration of 3D printing technology by Lawrence Laboratory, and his mind was alive.

Although the Americans did not show their top technology, as a professional who has been immersed in the metal casting industry for ten years, Yao Chongshan can basically judge that even if the Americans have not fully mastered the technology of 3D printing metal, they have already touched the threshold of this technology.

This made him sigh at the strong technical strength of the Americans on the one hand, and at the same time, he also had a strong interest in this 3D printing technology.

In the days of the meeting, he was actively looking for information, constantly consulting experts, the more he understood this technology, the more he felt emotional, and then the more he remembered this technology.

As an early technographer, after learning about such an emerging science and technology, he can be said to have quickly sunk into this technology.

Later, when his mentor wanted to return to China after the expo, he actually applied to stay in the United States for more than a month to learn about this technology, and his mentor was very unhappy at that time, because in his opinion, it was a complete waste of time and money, after all, this technology is still a chicken rib in the current view, and it is immature in many fields.

However, in the end, he agreed to his request, and in this month's time, Yao Chongshan went to several well-known universities in California to visit many experts and scholars to have an in-depth understanding of this technology.

Generally, these American experts will have a deep sense of defensiveness against Chinese people like him, but later it turned out that he was just a technophile obsessed with this way, and he asked about some of the most basic things, so they patiently answered his questions.

And it is these entry-level knowledge, but he is even more addicted to it, and when the visa expires and he has to return to China, he even paid out of his own pocket to buy some of the private money accumulated by following his mentor to do projects with his mentor for several years, about tens of thousands of yuan, all of which were purchased books on 3D printing technology, and then packed back to China.

After returning to China, he was even more obsessed with this way, and his behavior seemed to his teacher to be a bit crazy, not doing his job.

If it weren't for the fact that he had followed his teacher for many years, it would have been difficult for him to pass his doctoral dissertation at the end.

When he was about to graduate and leave school in two months, Yao Chongshan was also faced with several choices, whether to go to those domestic iron and steel companies to work.

Or simply go abroad to study for further study, or stay in the school to teach, and then rely on the resources of the school to engage in scientific research that you are passionate about.

In fact, the best choice is to go to work in a steel company, after all, the salary is high and the benefits are good, but Yao Chongshan is not a person who particularly values money, in his heart, it is this scientific research that is the most important.

But if I stay in school, can I get support from the school for the project I want to do?

This 3D printing technology is very promising in my opinion, but can the school leaders understand and support themselves? Yao Chongshan felt very bottomless. (To be continued......)
