In fact, in China, the most successful company in the research and development of machine tools is Huaxia Industrial Technology Co., Ltd. A year ago, it had manufactured machine tools that were as good as those of the German Andrews Company. However, these technologies were not fully disclosed because Huaxia Industrial Technology did not
The difference is just from the sales of Transformers models every year.
You can get millions of dollars, and Professor Xiong and the others don’t think this is something worth showing off. What you are copying is just a third-rate foreign product, which is embarrassing if you take it out. Now Huaxia Industrial Technology has begun to develop second-generation machine tools, and
With a big breakthrough, this is a product that can be used.
Of course, when it comes to technology, the things in Liu Lang's mind are top technologies. As long as all these technologies become reality, the country's industrial level will definitely improve a lot. If it is popularized among enterprises across the country, not to mention the United States,
Compared with first-class manufacturing countries like Germany, the island country can compete with other developed countries in Europe.
When Liu Lang saw these bidding materials, he was also moved in his heart. These companies want to introduce foreign technology, but in terms of technology, he already has some in his hands!
"Is there any technology we can do here?"
Liu Lang asked while flipping through the information.
"Mr. Liu, take a look at the bidding project of the Guangdong Provincial Electric Power Department. I think we can give it a try!"
Chen Wei on the side found a copy of the information and handed it to Liu Lang.
"Jibei Province 400,000-kilowatt unit bidding project...!"
This information is very detailed, and there is even a bidding plan for each project, which is similar to a tender document. If it weren't for Wang Zhendong's relationship, ordinary companies would not be able to obtain it.
"Mr. Liu, this project is huge, and there are some things we can't do yet, but look at this!"
"The manufacturing and welding project of high-strength pipe fittings with a diameter of 750 centimeters!"
Liu Lang's eyes lit up when he saw this bidding project.
The construction of thermal power stations requires a large number of pipe fittings. The main categories are elbows, tees, reducers and plugs. Each category has many varieties. For example, elbows are divided into hot-pressed elbows.
Push elbows, welded elbows, die forged elbows and cold pressed elbows, etc. There are also tees, including forged tees, forged welded tees, welded tees, spherical tees and hot pressed and cold pressed tees.
Wait.
As pipe fittings in thermal power stations, especially pipe fittings at the core of power generation, they must withstand high temperatures and pressures, and the quality and requirements for pipe fittings are much higher than those in other industries.
At this stage, the country's largest thermal power stations are all 300,000 kilowatts. At that time, the maximum output power of Fucheng Power Plant was 300,000 kilowatts, but that was the maximum design output power, and it was much less than this standard under normal working conditions.
Now Jibei Province is going to build a thermal power station with an output of 400,000 kilowatts. Of course, it cannot be said to be a new one. They may be renovating and upgrading the original thermal power station, but this kind of project to increase the power to 100,000 kilowatts at once is not just a new one.
Corresponding pipe fittings become larger
Making it thicker is as simple as changing the material first. The original material may not be able to adapt to the new pressure and temperature conditions. It is also clearly stated in the tender document that the material of the pipe fittings must be carbon structural steel or carbon structural steel that meets international standards.
Standard alloy steel.
There are very few countries with these two types of steel at this stage, and then the steel needs to be redesigned, molded, forged, and finally welded into shape. This series of work is basically impossible for countries at this stage to complete.
But Liu Lang can do it! At least in the welding stage, he can use the most advanced reinforced welding technology in the country to strengthen and weld it.
Liu Lang estimated that this project would require dozens of tees and elbows. However, these tees and elbows were huge. The largest ones might have a diameter of nearly one meter. The stamping technology alone was the most advanced in the country.
No company can complete it at this stage, because it requires the use of a hydraulic press of at least 5,000 tons. The price of such a hydraulic press is nearly 10 million yuan, and this part must be left to foreign companies in the end.
In addition, the people who can complete the welding work of such a large diameter pipe in China must be at least a seventh-level welder, and because the strength of the material is very high, the welding is naturally more difficult, and there may not be many workers who can complete these tasks.
Obviously Jibei Province has not thought that domestic companies can complete this work. They should face foreign companies, especially those from island countries, because the power technology of island countries is very developed.
"Well, if we build a new generation of stainless steel smelting furnace, all this work can be taken over!"
Liu Lang sighed.
Professor Xiong and other experts were stunned. They felt that Norinco could consider welding, but why did Liu Lang suddenly mention the issue of materials.
"Professor, the pipe material required by this thermal power plant is tb/1184-1996 carbon structural steel. The new generation stainless steel smelting furnace currently being developed by Huaxia Industrial Technology can actually forge this kind of steel. It only needs to make small changes.
But, just
The new generation of smelting furnace is still in the experimental stage and has not been put into industrial mass production. If it can be mass produced, I can directly use it to smelt these materials, and the cost will be at least about 30% less than abroad. What a pity! What a pity.
This thermal power station in Jibei Province is doomed!"
Liu Lang smiled and said.
However, Liu Lang was right. A year ago, Liu Lang came back from the United States and brought back the drawings of the latest stainless steel smelting furnace. This new type of smelting furnace can reduce energy consumption by 30%.
In addition, it can also smelt better stainless steel. At that time, the country also attached great importance to it and allocated two million yuan in special funds to Huaxia University for this purpose.
In fact, Huaxia University has already produced a prototype this year, which is completely ready for production, but it has not yet been officially put into industrial production.
It’s not that I didn’t want to, but I found several factories and no one was willing to spend the money. The reason is very simple, that is, the first-generation smelting furnace was industrialized just two years ago. For this reason, the Shencheng Manufacturing Factory and the Shanghai Manufacturing Factory invested
We have invested nearly 20 million yuan to manufacture nearly 100 smelting furnaces every year, achieving the goal of annual production of millions of tons of 304 stainless steel.
After spending so much money, they finally industrialized the stainless steel smelting furnace, and the 304 stainless steel model can meet domestic demand. Now they only need to increase production to make a lot of profits. In this form, who will invest heavily?
Funds to manufacture a new generation of stainless steel smelting furnaces?
The manufacturing plant was unwilling to invest money, and Huaxia Industrial Technology focused its energy on a new generation of machine tools, so the latest smelting furnace was put aside.
Now that Liu Lang mentioned this matter, Professor Xiong Huaizhi also thought about it, and his face became a little ugly, feeling that he had not done a good job.
"Professor, that smelting furnace should still be placed in the laboratory of Huaxia Industrial Technology! I will pay two million to buy that furnace back when I have time. I will build it when I have time, otherwise it will take another two years.
That furnace is going to be obsolete!"
Liu Lang said with a smile.
"Forget it, you are willing to spend money to build it. Others are short-sighted. They obviously have ready-made technology but don't use it. In the end, they have to spend a lot of money to use foreign technology. Alas, I don't even know what to say...
...By the way, Liu Lang, you said that furnace can smelt carbon structural steel, how to modify it?"
Professor Xiong suddenly changed the topic. He was very curious about the process.
