In fact, in China, the most successful research and development of machine tools is Huaxia Industrial Technology Co., Ltd., a year ago has manufactured a machine tool with performance no less than Andrews in Germany, but these technologies are not fully public, because Huaxia Industrial Technology is not bad for money, every year just from the sale of Transformers models can get millions of dollars, and Professor Xiong They don't think this is anything worth showing off, you imitate just foreign third-rate products, take out are embarrassing, now Huaxia Industrial Technology has begun to develop the second generation of machine tools, and there is a great breakthrough, this is the product that can be used。

Of course, if it comes to technology, what Liu Lang has in his head is the top technology, as long as all these technologies become reality, then the country's industrial level will definitely improve a large piece, if it is popularized in the national enterprises, not to mention compared with the United States, island countries and Germany and other first-class manufacturing countries, it can also be compared with other developed countries in Europe.

Liu Lang saw these bidding materials, and his heart was also moved, these companies want to introduce foreign technology, but in terms of technology, they have some in their hands now!

"Is there any technology we can do?"

Liu Lang asked while flipping through the information.

"Mr. Liu, look at the bidding project of the Guangdong Provincial Electric Power Department, I think we can give it a try!"

Chen Wei, who was on the side, took out a copy from the information and handed it to Liu Lang.

"Jibei Province 400,000 kilowatt unit bidding project ......!"

These materials are very detailed, and there are even bidding plans for each project, similar to bidding documents, if it were not for Wang Zhendong's relationship, ordinary enterprises would not be able to get it.

"Mr. Liu, this project is very big, and there are some that we can't do for the time being, but look at this!"

"750 cm diameter high-strength pipe fitting manufacturing and welding engineering!"

Seeing this bidding project, Liu Lang's eyes lit up.

The construction of thermal power stations requires a large number of pipe fittings, the main classification is elbow, tee, reducer and plug these four categories, and each category has many varieties, such as elbows are divided into hot pressed elbows, push elbows, welded elbows, die forging elbows and cold pressed elbows, etc., as well as tees, forging tees, forging and welding tees, welded tees, spherical tees and hot pressing, cold pressing tees and so on.

As the pipe fittings of thermal power stations, especially the pipe fittings at the core of power generation, they have to withstand high temperature and high pressure, and the quality and requirements for pipe fittings are much higher than those of other industries.

At this stage, the country's largest thermal power stations are 300,000 kilowatts, and the highest output power of Fucheng Power Plant was 300,000 kilowatts, but that was the highest design output power, which was much smaller than this standard under normal working conditions.

Now Jibei Province wants to have a thermal power station with an output power of 400,000 kilowatts, of course, it cannot be said that it is new, they may be reconstructed and upgraded on the basis of the original thermal power station, but this kind of project to upgrade 100,000 kilowatts at once is not just to make the corresponding pipe fittings bigger and thicker, first of all, there must be changes in the material, the original material is likely to be unable to adapt to the new pressure and temperature conditions, the tender is also very clear, the material of the pipe fittings should be made of carbon structural steel or alloy steel that meets international standards.

There are very few countries at this stage of these two kinds of steel, and then the steel has to be redesigned for forging, and finally welded and formed, which is basically impossible for the country at this stage.

But Liu Lang can! At least in the welding stage, he can use the most advanced reinforced welding technology in China to reinforce and weld it.

Liu Lang estimated that this project probably needs to have dozens of tees and elbows, but these tees and elbows are huge, the largest may have a diameter of nearly one meter, just stamping technology at this stage in China no company can be completed, because this requires at least 5,000 tons of hydraulic presses, the price of this hydraulic press is nearly 10 million yuan, this part of the final to foreign companies to do.

In addition, the people who can complete such a thick pipe diameter welding work in China must be at least a seventh-level welder, and because the strength of the material is very high, the welding difficulty is naturally greater, and there are probably not many workers who can complete these jobs.

Obviously, Jibei Province did not think that domestic enterprises could complete this work, and they should be facing foreign enterprises, especially those in island countries, because the power technology of island countries is very developed.

"Alas, if we build a new generation of stainless steel smelting furnaces, this work can be all done!"

Liu Lang sighed.

Professor Xiong and several other experts were stunned, they thought that North Industry could consider this part of welding, but why did Liu Lang suddenly talk about the material problem.

"Professor, this thermal power plant needs pipe materials TB/1184-1996 carbon structural steel can, Huaxia Industrial Science and Technology is developing a new generation of stainless steel smelting furnace can actually forge this steel, only need to make a small change, but the new generation of smelting furnace is still in the experimental stage, there is no industrial mass production, if it can be mass-produced, I can directly take it to smelt these materials, and the cost is at least about 30% less than foreign countries, it's a pity! It's a pity that this Jibei Provincial Thermal Power Station didn't have this life!"

Liu Lang smiled and said.

However, Liu Lang is still very right, a year ago Liu Lang came back from the United States, the latest stainless steel smelting furnace drawings also brought back, this new type of smelting furnace can reduce energy consumption by 30%, but also smelt better stainless steel, at that time the state also attached great importance to it, for which Huaxia University also allocated two million yuan of special funds.

In fact, in this year, Huaxia University has already manufactured a prototype, which can be put into production, but it has not yet been officially industrialized.

It's not that I don't want to, but no one wants to spend this money after finding a few factories, the reason is very simple, that is, the first generation of smelting furnaces just realized industrialization two years ago, for which Shencheng manufacturing plant and Shanghai manufacturing plant invested nearly 20 million yuan to manufacture nearly 100 smelting furnaces every year to achieve the goal of producing millions of tons of 304 type stainless steel per year.

So much money smashed into the stainless steel smelting furnace industrialization, and 304 model stainless steel is able to meet domestic demand, now they only need to increase production to earn a lot of profits, in this form, who will invest a lot of money to manufacture a new generation of stainless steel smelting furnace?

The reluctance of the manufacturer to invest money, coupled with the fact that Huaxia Industrial Technology has focused on the new generation of machine tools, has put the latest smelting furnace aside.

Now that Liu Lang mentioned this, Professor Xiong Huaizhi also thought about it, his face was a little ugly, and he felt that he had not done his job well.

"Professor, that smelting furnace is still in the laboratory of Huaxia Industrial Science and Technology! I will pay two million, and when I have time to buy that furnace back, I will build it when I have time, otherwise the furnace will be obsolete in two years!"

Liu Lang said with a smile.

"Forget it for you, and you are willing to spend money to build it, others are short-sighted, obviously they have ready-made technology but don't use it, and in the end they have to spend a lot of money to use foreign ones, alas, I don't know what to say............ By the way, Liu Lang, you said that furnace can smelt furnace carbon structural steel, how to transform it?"

Professor Xiong suddenly changed the subject, and he was very curious about the process.

Set a small goal first, such as remembering in 1 second: book guest residence
