After a long wait, this furnace-oriented silicon steel slab was finally baked, and it was immediately sent to the vertical descaler to remove the iron oxide scale once, and entered the R1 roughing mill for rolling once, and then rolled 5 times through the R2 roughing mill, followed by R3 and R4. Then the steel strip is rolled into steel strip by the F1 to F7 finishing rolling mills, and the thickness measurement, width measurement, temperature measurement, and laminar flow cooling are carried out to directly test the quality of the silicon steel in the hot-rolled state without bundling.

The hot rolling mill is star-studded, the workshop masters show their talents, and the cadres and engineers are nervously watching.

"No holes!"

"No edge cracks!"

"No heavy skin!"

"Mild scarring!"

The factory director personally supervised the work, and the quality inspectors were enthusiastic and the work efficiency was extremely high.

This furnace of silicon steel happens to be D340 that has been approved for mass production, and it is very expensive.

No major quality problems were found, and Director Wu was more relieved, and he ordered loudly: "Flame Class C, give it to me!"

The venerable, lovable, and powerful flame workers are back on the scene, and the mild scarring obediently surrenders under the crush of the thousand-degree flame gun.

There are thousands of bright skins, and there is one simple soul.

The value of silicon steel is not only reflected in the appearance, but most importantly in the soul --- magnetism.

According to the test of workshop technicians, the magnetic properties of this furnace D340 in the hot-rolled state are 1.905 (iron loss) and 1.523 (magnetic induction strength under 800A/m magnetic field).

Scientific appraisal shows that the surface quality and magnetic properties of D340 sprayed with Jianggang's self-developed paint are the same as those of D340 sprayed with Nippon Steel paint.

The summary is: there is no problem with steel!

As far as the matter is concerned, the D340 product patent and the supporting silicon-silicon carbide protective coating sold to Jianggang by Dongying people are still very conscientious and high-end goods.

Most of the world's silicon steel products and process technology patents are concentrated in Japanese iron and steel enterprises, and these Japanese companies have taken extremely strict confidentiality measures for these patented technologies, and there are few published research results.

Zhao Qingshan has swiped so many documents in the reference room, and most of the sources of papers or monographs are from Europe and the United States, and it is rare for Japanese researchers to report on their research. Even the jumping stimulation recall method can only stimulate a small amount of Japanese information.

Half of the equipment in the "1.7 meter rolling mill system" (about 300 million US dollars at the time of the contract) was supplied by Japanese companies, and in the context of state-to-state cooperation, the companies transferred some unreported patented technologies to Jianggang.

The product patent of this furnace D340 is digested from Nippon Steel's patent, but the supporting magnesium oxide-chromium trioxide protective coating is self-developed by Jianggang.

All in all, the three stinkers have taken a solid small step on the road of independent innovation.

"Director Wu, today's results are gratifying, the surface quality and magnetic properties of this furnace D340 are all up to standard. As the undertaker of the project, Ma Hanxing made a summary of today's work.

"Thank you for your hard work. "Director Wu's heart rested in his stomach, to be exact, temporarily in his stomach.

The battle continues.

On October 26, the No. 3 furnace of the hot rolling mill was in normal operation, and the quality of the oriented silicon steel produced was qualified.

The same is true on the 27th~31st.

Ma Hanxing, Zhao Qingshan, and Zhou Tienan divided the labor, one squatted in the hot rolling mill, one squatted in the coking plant to follow up the batch preparation of self-developed coatings, and the other wandered.

Since the beginning of the week, the situation in all aspects has been in line with their expectations, and the key node is November 25.

After squatting in the workshop on November 1, Zhao Qingshan got off work on time, and he could only squat during the day shift, after all, he was a man with a wife.

Riding back to the 12th neighborhood, Zhao Qingshan saw Meng Shuizhi squatting at the door of the unit building, smoking.

Zhao Qingshan parked and locked it, and he asked, "Master Meng, what class?"

"Night shift. Meng Shuizhi took out a cigarette and handed it to Zhao Qingshan: "Eat cigarettes and eat cigarettes." ”

Zhao Qingshan took the cigarette holder and put it on his ear, the cigarette is a swimming cigarette, a very cheap cigarette.

Meng Shuizhi's salary is higher than Zhao Qingshan's, and he smokes some good cigarettes, which he can afford financially. It may be because the old comrades are used to living a hard life, they have experienced this disaster and that famine, and the virtues of remembering the bittersweet memories and being diligent and thrifty continue to this day.

"If Xiaoqing can't get into college, I want to send him to be a soldier. Lao Meng suddenly said something, and said: "Staff Officer Wang of the Military Section has acquaintances in the Yangcheng Military Region, and this situation is that Captain Xu of the militia team told the squad leader Xu of the sintering plant, and the nephew of the squad leader Xu happens to be my apprentice, so I know." ”

"Master Meng, are you sure that Xiaoqing can survive a few years if he goes to the army?" Zhao Qingshan is not optimistic about Meng Xiaoqing's military career, not everyone is suitable for training in the army.

"There's no way around it, I just attended Xiaoqing's parent-teacher conference. Meng Shuizhi took out a list and gave it to Zhao Qingshan: "Xiao Zhao, look, his grades still can't go up." ”

Zhao Qingshan took the list and checked it carefully, this is the third and third class score ranking card, it has a heavy ink smell, the students' names, subjects, and scores are all handwritten, and several copies are mimeographed, and they are sent to each parent.

There are a total of 57 students in the third and third classes, and Meng Xiaoqing ranks 42nd.

Meng Xiaoqing is not the worst student, isn't this still pressing 15 people.

In the most recent exam, Meng Xiaoqing scored 250 points.

Zhao Qingshan was slightly surprised: "Master Meng, you don't have to be too pessimistic, Xiaoqing took the exam two hundred and five, no matter how hard he works, he can pass three hundred points, and he can study junior college even if he can't study undergraduate." ”

Glancing up along the student's name, Zhao Qingshan found his wife's name, the wife is awesome, the fifth in the class!

"More than 300 points are difficult to test. Lao Meng was obviously pessimistic, and he said in a pleading tone: "Xiao Zhao, you graduated from a prestigious university, you are educated, can you tutor Xiaoqing?"

Not long ago, it was "you learn from your little brother", and now it is "counseling and counseling", which reflects the change in the mental journey of an old father.

Zhao Qingshan promised: "I took the college entrance examination in 82, and many years have passed, and some things have been forgotten. Those test centers in high school, I want to recall memories, and if the memories are almost complete, I can tutor Xiaoqing. ”

Lao Meng was overjoyed: "Okay, good! Thank you, thank you, thank you! Let's go to my house for dinner!"

The sister-in-law of the Meng family cooked at home after the morning shift, Meng Xiaolan did not go home from the middle class, Meng Shuizhi went to the night shift later, Meng Xiaoqing stayed at home for an hour and then went to school, it was difficult for a family of four to have a meal, and Zhao Qingshan became a stable customer of the Meng family

also figured out Zhao Qingshan's taste preferences, and the Meng family's sister-in-law eliminated eggs from her ingredients.

Xitou fish, roasted pork ribs, mixed tofu, stir-fried vegetable sprouts, two meat and two vegetarian dishes, red and hot, clear and white.

The meal does not contain any eggs, not even the species that laid the eggs.

In the past, it was coarse tea and light rice, and if you wanted to bring some oil and water, you had to get up in the middle of the night and queue up to buy lard.

And now, we don't even want to eat fat!

If it weren't for the line of the Third Plenary Session of the 11th CPC Central Committee, how could there have been such a great improvement in life.

At the dinner table, the focus of the topic was Meng Xiaoqing, the grades, the scores, and the college entrance examination.

Zhao Qingshan said: "Xiaoqing, give me your textbooks, review materials, and test papers." You can just bring a topic to school and give me the rest. I need to review the key points of the college entrance examination. ”

Meng Xiaoqing did so, and he was happy to accept Brother Xiaoshan's individual counseling.

After eating, Zhao Qingshan returned to his house and was engrossed in reading various review materials for contemporary high school students.

In these years, there are no five or three golden classics and queen male collections, but there are always some reference books such as college entrance examination secret papers and question type explanations.

Zhao Qingshan was stimulated, recalled, and stimulated the 87-year science college examination paper and it was over.

However, it backfired.

Memories related to the previous high school examination papers are blank.

It stimulated some information about the top students in the college entrance examination.

In 1987, the top student in the science college entrance examination in Chuzhou Province was a classmate named Lei Jun from Xiantao Middle School.

With a total score of 710, Lei Jun scored 700 points, and Tsinghua University's science admission line in Chuzhou Province was 440 points, and Lei finally went to the Computer Science Department of Jiangcheng University.

There are only champions, and there are no high school exam papers, so it's a bit tricky.

Zhao Qingshan is an engineer, and he is not a gold medal lecturer.

"Meng Xiaoqing's English is okay, with a score of 66, which is the highest in all subjects. ”

Zhao Qingshan analyzed the current situation of Meng Xiaoqing's subjects one by one, this kid's English is not bad, could it be related to his love of playing game consoles?

K.O、Win、Boom、Combo…… There are many esoteric English words and sentences in the game, and interest is the best teacher.

It can only be explained so forcefully.

Meng Xiaoqing scored only 11 points in mathematics, while he scored 52 points in physics.

He scored a measly 7 in biology and a whopping 61 in chemistry.

Language + Politics, he scored a total of 53 points.

From the analysis of paper data alone, Meng Xiaoqing's routine is very fascinating.

Chinese composition is nonsense, but English composition is fluent.

The mathematical calculation problem only has a solution, but the physical calculation problem is full of pictures and texts...... Although the result was miscalculated (unfortunately wrong), the process scored a few points.

Meng Xiaoqing, what kind of exercises are you practicing?

Zhao Qingshan had to re-examine Meng Xiaoqing, don't look at this kid's total score is not high, but he is a geek!

And my wife is an all-rounder, her scores in each subject are very average, maintaining a level of about 400 points, and she has no problem being admitted to a key university.

Zhao Qingshan's decision-making is wise, don't alarm his wife first, let her review with peace of mind and actively prepare for the college entrance examination, she only needs to play normally, and she can repeat the plot of the previous life.

At nine o'clock, before anyone arrived, the sound came first.

"Brother Xiaoshan, I'm back, hurry up and tutor me!"

Meng Xiaoqing rushed into Zhao Qingshan's house, and his enthusiasm for learning was high.

Zhao Qingshan was surprised: "You suddenly love learning, what's the matter?"

Meng Xiaoqing rarely calmed down and matured, he said: "It's still the same sentence, I understand the truth, if I have the opportunity to study in college, why don't I study? As the saying goes, people don't kill the heavens and the earth for themselves, and good birds choose trees to perch. ”

"Mature thinking, clear intentions, accurate words, and smooth sentences, I can't figure it out, Meng Xiaoqing, why is your Chinese composition score in the single digits? Are you doing it on purpose?"

"I didn't mean to! I don't want to be a soldier!"

"It turns out that this is your real motive, you go back to wash and sleep first, I have to review the materials for a few days before I can start tutoring you. ”

Zhao Qingshan sent Meng Xiaoqing away, and he handwrote an English essay "A puma at large" on a blank piece of paper.

This new concept of "A puma at large" is included in Zhao Qingshan's first contact with it, and it is a reference book for college students to prepare for IELTS and TOEFL.

Not too many teenagers, the post-00s have grown up and entered school, and this version of the new concept has become a learning material for post-00 junior high school students.

The world is changing so fast that people can't figure it out.

It is no exaggeration to say that post-00s junior high school students traveled to the 80s to take the English test, and they have the strength to get a full score in English in the college entrance examination.

Zhao Qingshan wrote by hand until late at night, and his articles include "A puma at large", "Thirteen equals one", "An unknown goddess", and "The double life of Alfred Bloggs......

He likes the article "The Double Life of Alfred Brogess", the protagonist of the article, Alfred, as a real cleaner and a fake white-collar worker, deceived his wife for a lifetime, revealing the humanistic characteristics and values of Western society, which is thought-provoking and thought-provoking.

Interactions between people don't have to be utilitarian.

Zhao Qingshan wrote a series of short stories in English, which consumed a certain amount of his spare time.

In mid-November, Zhao Qingshan was rotated to a wandering position.

If Ma Hanxing and Zhou Tienan, who were squatting in the workshop, called him when they encountered problems, he would go to the workshop to help.

Zhao Qingshan guards the Iron and Steel Research Institute, and he occasionally supports it, and spends most of his working time brushing literature.

The study of iron and steel is a comprehensive discipline, which is divided into three core systems: ironmaking, steelmaking and steel-rolling.

Further subdivision, there are many research fields such as technology, variety, corrosion coating, thermal energy, petrofacies, metals, material testing, chemistry, rapid analysis, experimental technology and so on.

Speaking of variety research, it is divided into silicon steel sheet, 4C shipbuilding plate, hot-rolled ship plate, ball flat steel, bridge steel plate, container steel plate, high-pressure vessel steel plate, boiler steel plate, heavy rail, square steel, channel steel, I-beam, automobile plate, cold-rolled ordinary tin-plated sheet, tin-plated sheet, cold-rolled deep-drawn sheet, ordinary carbon plate, low-alloy steel plate......

These steel varieties are used in various industries such as military industry, shipbuilding, aerospace, railway, transportation, construction, chemical industry, petroleum, energy and heat, machinery, automobile manufacturing, light industry, mining, food, electronics, instrumentation, electromechanical, power supply and so on.

A person's energy is limited, even if Zhao Qingshan does not eat or drink to engage in research, limited by the fixed cycle of experimental research, experimental production to production, and industrial production verification, he has reached the peak of completing 200 research topics in his lifetime.

You can only focus on the key points, and the important thing is the layout.

As a reborn steel worker, there are three words that Zhao Qingshan cannot avoid---- to reduce production capacity.

Again, that point, layout.

This year, if you tell the state at the two sessions to reduce production capacity, what awaits you will be a mental hospital.

Gold and silver mountains are not as good as green waters and green mountains. The bureau is laid out, and the appropriate capacity will be removed.

Reform and opening up has opened up our audio-visual and made us deeply aware of our own shortcomings and the direction of our efforts. The successful experience of foreign iron and steel enterprises is worth learning, and we should learn from it, and we should surpass it.

The eight major steels have their own destiny, let's cook wine together in 20 years and talk about heroes, the green mountains are still there, and the sword is pointing at the nine heavens.

Time flies, twenty years in a blink of an eye......
