Niu Shilong suddenly felt as sick as if he had eaten shit.
Although he really didn't know how many ways there were, he knew that he had read it wrong and it was definitely a big joke, because the expressions on everyone below told him so.
But, can he blame Qin Zhenhua?
It seems that Qin Zhenhua is not wrong. What is wrong is the person who wrote it. If he writes the Chinese characters correctly, can he read them wrong?
This writing is really sloppy. Could it be that Du Youwen did this on purpose to make a fool of himself?
Fortunately, Niu Shilong has seen the big world. Although he was embarrassed, he quickly covered it up. He pretended to take a sip of water, and then, calming his mind, he said: "Yes, it is oxygen acetylene. Now, you can start
Have you answered?"
I don’t believe you can tell me. The answers below are written one by one. It’s so complicated. Who can answer it for an ordinary master?
This answer must have been copied from a textbook, right?
"Okay, then I will start to answer." Qin Zhenhua is confident, articulates clearly, and the standard chatterbox announcer's pronunciation is average: "First, there is preparation work, which is divided into eight steps: Check the use of the equipment and the surrounding environment
Whether it is safe; remove dirt, etc.; mark and stake out according to the drawing; raise the cut piece and make it stable; check the injection and suction performance of the cutting torch; check whether the wind line is good; adjust the energy rate and nature of the preheating flame; wait for the above preparations
Make trial cuts after completion."
When Qin Zhenhua said this, everyone was stunned.
When it comes to gas cutting, all master craftsmen know how to do it, and they are very skilled in the preparation work. However, if this preparation work is standardized and stated one by one, no one can do it. Now if you say it, it will be like saying it.
Give them the same summary, clear and organized!
Niu Shilong also opened his eyes wide, right? It is absolutely impossible for this test question to be leaked. How did Qin Zhenhua know about it? What he said is completely correct, word for word!
"I will then answer the specific usage method, which is divided into four steps: ignition, starting cutting, normal gas cutting, and stopping cutting."
This is much more detailed than the previous one. When Qin Zhenhua said it, the jaws of the masters on the scene almost dropped. If I were asked, could you tell me?
Of course that's impossible. There's nothing else to say about the operation. You'll get it naturally if you practice more!
Qin Zhenhua still gave the standard textbook answer: "Before igniting, open the acetylene first, then slightly open the oxygen valve, and use a ignition gun or match to ignite. Under normal circumstances, a special ignition gun should be used for ignition. In the absence of a ignition gun,
Matches can also be used to ignite the fire, but attention must be paid to the operator's safety and not to be burned by the ejected flame. It starts with a carbonized flame. At this time, the oxygen flow should be gradually increased to adjust the flame to a neutral flame or a slightly oxidizing flame.
of flames.”
………
"Stop cutting: At the end, the cutting torch should be tilted at an angle in the opposite direction of gas cutting, so that the lower part of the steel plate can be cut through in advance, so that the cut looks neat at the end. Finally, close the oxygen valve and acetylene valve, and the entire gas cutting process
That’s the end.”
In the factory, no one has ever been able to answer so clearly, understandably, and word for word. For the average old master, it is just words and deeds. Who will read the book?
Qin Zhenhua's figure immediately grew taller in front of their eyes. This level was enough to teach them. Yes, several Soviet instructors came here one year. When teaching them, this should be what he said.
, but the translator was exhausted at that time.
"By the way, I have to add that when the thickness of the steel plate is more than 25mm, a large cutting torch and cutting nozzle should be used, and the preheating flame and cutting oxygen flow should be increased. During the gas cutting process, the cutting speed should be slow and appropriate.
The ground makes a horizontal crescent-shaped swing to widen the incision and allow slag to be discharged."
After Qin Zhenhua finished speaking, he also felt thirsty. He picked up the enamel cup on the table, took a sip of water, moistened his throat, and said to the stunned Niu Shilong above: "Director Niu, was my answer correct?"
If this kid has never read the test questions, he is really knowledgeable. He actually knows all these things?
"This, um, no problem." Niu Shilong couldn't say that he was wrong, after all, this was the standard answer.
"Wow!" In an instant, someone below applauded and shouted: "Okay, great!"
This voice was that of a girl, but it was hidden in the corner and no one could be seen. However, driven by this applause, others also applauded.
I admire you. This is a learned person. In the factory, there is probably no master who can do this!
Niu Shilong felt annoyed. He originally planned to use this method to embarrass Qin Zhenhua today, but who would have thought that it would make him stand out instead?
How could he recite it so clearly?
I am preparing to go to Tsinghua University. If my brain is not good, how can I have this ideal? Qin Zhenhua has a special sense of loneliness there. Although he cannot remember the book after reading it, as long as he connects theory with practice after reading it, he will naturally
If you can memorize these operating regulations clearly, it will certainly be difficult for you to test yourself on this.
Niu Shilong felt that he could no longer perform. He failed to pass the test and instead made a fool of himself. So, should we continue? Or should we give the test questions to Song Weize and let Song Weize take the test?
For this second question, what if I read it wrong again?
With this thought in mind, Niu Shilong opened the next question. Suddenly, his eyes lit up. I don't believe you can answer the second question.
Because even Niu Shilong couldn't understand, the answer to this second question was a series of formulas!
For old masters, they usually rely on experience. It is impossible to calculate with formulas. They don't have that level, especially now. It is obvious that there are some symbols in the formula, and even I can't
I don’t know, it’s not about addition, subtraction, multiplication and division, there’s even a graph, it’s so professional! Gee, only the guys in the R&D room can come up with such a question!
Niu Shilong read it carefully twice, making sure that he would not misunderstand the words in the above test questions and make a joke, so he started again with confidence.
"Qin Zhenhua answered the first question very well. Now, we should take the second question." Niu Shilong said enthusiastically: "A three-phase asynchronous motor, model Y-90L-4, with a power of 1.5 kilowatts and a speed of 1400.
The power factor is 0.79, how to adjust it to make its speed reach 1800."
In fact, there are still a lot of letters, but Niu Shilong simply skipped them all to avoid being called a layman. Now, it depends on how Qin Zhenhua answers it. If he needs paper and pen, he can also have someone give it to him.
When this question was read out, the masters all started shaking their heads. This made Niu Shilong wonder, could it be that he had read it wrong again?
