Ma Ming and these people worked in the North Industries Group for three months, although the time was very short, but they were in contact with the best equipment in China, and there was no one, Zhao Yongsheng had only heard of the intermediate frequency furnace Ma Ming used casually.

It is really easy to heat with the intermediate frequency furnace, the whole furnace does not need any coal and coke at all, and then the skin effect is formed on the surface of the metal material by electromagnetic induction, the heating is rapid and the heat is uniform, and there is a digital display system to display the temperature at any time, which can control the temperature in the range of ten degrees.

After using this intermediate frequency furnace and then looking at the coal coke oven, it will involuntarily give birth to the idea of contempt, if you look at the artificial heating method, it will be like returning to the primitive society, so Ma Ming and the three of them couldn't help laughing, feeling that this expert from the Ministry of Electric Power is nothing more than that!

Feng Liyong's face was a little unbearable, but he was also a little impressed by Liu Lang, the other party said that it was the first time he had heard of the data about carbon structural steel, could it be that this Liu Lang really had some ability?

"Liu Lang, you're right, but it's useless, the conditions here don't meet the requirements you said, then we don't know if your skills are real............! ”

Feng Liyong was about to refuse, but Liu Lang waved his hand.

"The welding technology is universal, a welder can process carbon structural steel, and naturally can also weld other metal materials, it doesn't matter if you don't have an intermediate frequency furnace here, then we will process other metal materials, 304 stainless steel?"

"Yes, yes, now our country can smelt 304 stainless steel by itself, and our power plant now has dozens of pipes of different types, the largest is 50 centimeters in diameter, and the smallest is 10 centimeters, which can be used!"

Zhao Yongsheng replied immediately, he was a little happy to see Feng Liyong deflated, and at the same time surprised, this kid is really powerful, just a few words made the "arrogant" Feng Liyong lose his arrogance.

"Okay, you can have this kind of steel, in addition, you also have metal material testing equipment here, it is best to have more than 3,000 tons of hydraulic destructive test equipment, so as to cause tearing of 304 stainless steel. ”

"We also have this, not just 3,000 tons, we also have 4,000 tons of destructive equipment here, that's no problem!"

"Director Zhao, and this material, you should also have it here, right?"

Liu Lang picked up the pen and put some materials under the paper, all of which were powders of materials such as vanadium and titanium, which were not uncommon, and factories that often welded would equip them.

"This ...... Well, no problem, we have everything that Mr. Liu wants!"

"Okay, you go and prepare according to my requirements, we have brought our own equipment, you only need to provide five bottles of oxygen acetylene, three tanks of oxygen and two cans of acetylene, and a bottle of argon.

The purity of oxygen should reach more than 90 percent, and we have brought the rest of the welding torches and protective gear, Brother Ma, the three of you go back and get them now!"

Oxygen and acetylene are naturally used for heating, while argon is used for cooling.

Argon was not very commonly used in China, and carbon dioxide was used for welding in the past, but with the large use of stainless steel, carbon dioxide as a cooling gas is no longer suitable for the welding of stainless steel, and argon has gradually begun to be used.

Zhao Yongsheng wrote down all the requirements made by Liu Lang, he had heard many of the other party's requests, at this time he felt that the other party didn't seem to be joking, could it be that Liu Lang really mastered this incredible technique?

Ma Ming and the three of them immediately went back to get the equipment they brought, in fact, in addition to the equipment, they also had to go to that kind of catalyst, which was made of manganese, thumpher, vanadium, Nickel and other metal synthesis of powdered materials, the ratio between is very strict, and is confidential, only Liu Lang knows, in the conventional high-carbon steel reinforcement welding to add this catalyst, can be welded at the metal lattice of a slight change, this lattice change is the fundamental reason for strengthening the properties, of course, welding technology is also crucial, the operator to judge the degree of fusion of various elements by color.

Seeing that Ma Ming and the others were going to get something, Zhao Yongsheng immediately instructed his subordinates to let the driver pull the three of them to the power plant guest house.

"Xiao Sun, you immediately prepare according to the things on Mr. Liu's paper and see how much time it takes?"

One of them took it and looked at it.

"Factory director, I think it's about two or three hours, the key is that the concentration of oxygen exceeds 90 percent, we have to refill it, it's very slow, and the others are ready-made!"

"Mr. Liu, it takes two or three hours!"

"Director Zhao, then we'll come back after dinner in the evening!"

It's almost four o'clock now, and it's six or seven o'clock in two or three hours, so you can't wait hungry!

"Okay, okay, Minister Wang, Mr. Liu, Expert Feng, let's do this, I'll be the east tonight, please have dinner, let's work when we're full and drink, okay!"

"Okay, I'll also talk to Feng Lao, then I'll trouble you Director Zhao!"

Liu Lang nodded in agreement.

"Come on, I'll go and let the master of the kitchen prepare, let's eat some of our specialties in Jibei City!"

This is a great opportunity to make friends with Liu Lang and Minister Wang, and Zhao Yongsheng certainly can't miss it.

"Director Zhao, don't get me any bear's paw deer antler or anything, I won't eat those things!"

"Mr. Liu, don't worry, Director Wu has told me, and I will ensure that you are satisfied when the time comes!"

In the evening, Zhao Yongsheng invited everyone to dinner, Liu Lang had a total of six people, Zhao Yongsheng brought two assistants, one was also the deputy director in charge of sales, and the only characteristic was that he could drink.

Feng Liyong's expert group is a total of ten people, and the few people Liu Lang saw are actually apprentices brought by Feng Liyong, of course, the so-called apprentices are actually engineers with more than ten years of experience, but there is still a distance from Feng Liyong's level, and the other people are old experts who are about the same age as Feng Liyong, so they naturally will not follow Feng Liyong every day.

Counting these expert groups, they are also about to return to the capital, their preliminary work is basically completed, and they will come back as Chinese experts when the bidding meeting is officially held in the New Year.

A total of eighteen people were divided into two tables, Liu Lang, Wang Zhendong, Zhao Yongsheng, Feng Liyong, these leaders were at one table, and the others were at the other table.

Liu Lang nodded, today is to let Ma Ming and the three of them relax, but he also told the other party that it is okay to drink, but not too much.

No matter what era it is, the workers are very fond of drinking, Ma Ming and they are all young people in their thirties, and they often get together for a drink when they have nothing to do.

Their alcohol consumption is very good, but Liu Lang spoke, they can't drink more, those experts from the Ministry of Electric Power are not young, and they can't drink much, Zhao Yongsheng naturally didn't dare to let his deputy pour wine vigorously, so he didn't drink much, and the average person was less than a pound of liquor............!

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