"The No. 3 furnace is repaired more frequently than the other furnaces, and during the 15 days of the No. 3 furnace maintenance, only the non-oriented silicon steel can be fired by the No. 2 furnace. Under the condition that the single furnace repair cycle remains unchanged, the furnace is repaired once by burning 5000 tons of oriented silicon steel, which is improved to burn 6000 tons of furnace repair, and the heating amount of the slab in a furnace repair cycle is increased, and the furnace can be repaired several times a year, and the cost is also reduced. If we achieve the goal, we will create an economic benefit of about 3.085 million yuan per year. ”

Zhao Qingshan still talked about the background of the project first, but this time Director Ye did not interrupt him, but listened carefully and turned to the page of the economic benefits of the project task book.

"Your idea is good, invest tens of thousands of yuan in research funds, and create millions of benefits, who doesn't want to?" In the face of economic benefits, Director Ye was reasonable, and he said: "You three stinkers, can you really stand up to a Zhuge Liang? If the three of you solve this problem, you will be the heroes of Jianggang." So can you solve the problem smoothly, I'm going to put a big question mark. ”

It's over, Director Ye has a question mark!

Big!

Ma Hanxing chuckled in his heart, something was wrong.

Zhou Tienan was also nervous. Glory and disgrace together, you have me, the team spirit of the three stinkers is extremely touching.

"Some steel mills at home and abroad use liquid slag removal technology to increase the heating capacity of slabs in a furnace repair cycle, but the effect is average. Therefore, we should make a fuss about protective coatings, and I agree with the general direction of the task book you have done. Director Ye agrees with the overall idea of the project, and his view on the technical details is: "Studies under laboratory conditions at home and abroad show that the λ value of magnesium oxide-chromium trioxide coating is higher than that of liquid iron oxide slag at high temperature, which is conducive to convective heat transfer, reducing the burn-out rate, and increasing the heating capacity of the slab. ”

"Your technical target is 50%, 6,000 tons, which is already beyond similar products from Nippon Steel. The core technical link of this topic is how to formulate a new type of magnesium oxide-chromium trioxide coating to achieve the great goal of 50% and 6,000 tons. My personal point of view is that if you have a seven-point chance of winning, you can go all out! Technological innovation is such a thing, there is no need to stick to the inherent thinking, the initiators are often crossing the river by feeling the stones, how can there be ready-made things for you?" Director Ye looked at technical problems with rational thinking, and set the tone of the topic with a strategic vision and pattern.

Of course, this is my personal opinion and does not represent the opinion of the entire panel of judges. Director Ye looked left and right, and said, "Pei Gong, Han Gong, please express your opinions." ”

Pei Gong smiled slightly: "The odds of winning by five or six points are too risky, and the chances of winning by nine or ten points will delay the fighter, Director Ye is right, if there is a chance of winning by seven points, you should be bold to fight!"

Han Gong nodded and said: "There must be a focus on formula experiments, I suggest that more experimental resources should be invested in the additives of zirconium and zinc, and we must not be egalitarian, otherwise the funds will not be enough, and time and scientific research will be wasted." To sum up, I agree with the opening topic of "Solution for Serious Burning of Silicon Steel Oriented to the No. 3 Heating Furnace of Hot Rolling Mill", and look forward to the good news of the three scientific and technological pioneers. ”

Director Ye: "Then it was unanimously approved?"

"Pass!"

Three in favor, 0 against, the experts at the meeting reached a high degree of unanimity and approved Ma, Zhao, and Zhou Kai.

After all the procedures in the institute were completed, Ma Hanxing took a long breath: "The expert group approved the opening of the topic, mainly because the economic benefits of our subject are too tempting, and I will also approve it if I am the director of senior engineering." Invest tens of thousands of yuan at one time and strive for more than 3 million benefits per year, who wouldn't want to?"

"I sincerely hope that Ma Gong will be promoted to senior engineer director as soon as possible. Zhao Qingshan sent his blessings.

Three stinkers, more than 30,000 and more than 3 million, this pie can be painted too big.

Once it is done, it will be rewarded for meritorious deeds.

If you lose, the more than 30,000 yuan this year is not a small amount, and someone has to bear the consequences.

The person in charge of the project and the person in charge have to bear the consequences of failure, and Ma Hanxing and Zhao Qingshan are under pressure.

The project task book signed and approved by the institute was sent to the relevant cooperating units, written in black and white, and there was no turning back.

Experimental materials were bought back one after another, and Ma, Zhao, and Zhou Ren officially entered the first stage of research - laboratory research.

At the expert demonstration meeting, Ma Hanxing's most worried problem of "crossing the river by feeling the stones" was given clear instructions by Director Ye as if he asked and answered himself.

And Director Ye used a very vivid metaphor of "seven points of victory" to encourage the three of them to break through the routine and innovate boldly.

The three of them entered the specific operation stage and found that the difficulty was in the three uncertain factors.

With 99 kinds of experimental materials in place, Ma Hanxing once again mentioned the question he asked Zhao Qingshan earlier: "To turn three points of uncertainty into certainty, we use the method of violent elimination?"

Chemistry is ever-changing, and a large number of experiments are used to eliminate violence, and it is excluded to the Year of the Monkey?

The task book was written by Zhao Qingshan, who tinkered with bottles and cans, and said: "According to Han Gong's suggestion, we will make zirconium and zinc first." It's not just a matter of elimination, what if the right answer is found in the process of elimination? I prefer to call it the method of violent exploration. ”

"Xiao Zhao, do you have something hidden in your heart? I see that you are quite confident, and you must have hidden something if you only applied for more than 30,000 research funds. ”

Ma Hanxing's eyes suddenly burst out with a sharp essence, which was fleeting, turning into compassion and tenderness: "Xiao Zhao, what you said is also right, we are explorers, not destroyers. Let's get started, start exploring. ”

The three worked closely together and the experiment was in full swing.

Steelmaking is a song of steel and fire, a stage for the working class to show its strength, a game between various chemical elements, and a platform for scientific researchers to exert their wisdom.

At the beginning of the laboratory research stage, magnesium oxide-chromium trioxide coatings are more inclined to inorganic chemistry and analytical chemistry.

Magnesium oxide is the big brother, it comes from cheap industrial magnesia, and the proportion of ingredients in the formula should not be less than 75%.

Chromium trioxide is the second brother, and its proportion should be between 5% ~ 10%.

The rest are all junior brothers.

However, it is this group of younger brothers who play a decisive role, and the younger brothers also have spring.

Silica is indispensable, how much ferric oxide should be added?

What kind of status should be given to zirconium and zinc, which are the experimental materials of zirconium dioxide and zinc oxide that Han Gong emphasized?

With and with, in fact, oxygen is the real big brother.

Batches of experimental results came out one after another.

The EDAX analysis of the coating was too poor and failed!

The reflective map of the coating structure is too bad and fails!

The heating curve of the coated silicon steel specimen is actually a straight line, failure in failure!

The experiments of the trio failed consecutively, from September to October.

The weather is getting cooler, and the weather is cool for a good autumn.

"It's not funny. Ma Hanxing frowned, half of the experimental funds were consumed, and the bullshit didn't come out!
