It is necessary to know that the problem of quenching spots in products has been plaguing Xiangyang Machinery Factory for a long time.
After Ning Xiaohong served as the head of the technical section, he also organized everyone to brainstorm and think of many ways to overcome this problem, but it has been with little success.
It can be said that this problem has become the heart disease of Liao Jingsheng and Ning Xiaohong, and now that Zhao Guoyang can actually explain it in one sentence and come up with a solution, how can the two not be surprised.
However, Ning Xiaohong, who has a temper in Little Pepper, is not a person who surrenders so easily.
She thought about it, tilted her neck and said to Zhao Guoyang: "Comrade Zhao Guoyang, the method you just mentioned, after practical demonstration, can you 100% guarantee that you can definitely solve this problem without using pure water as quenching liquid?"
Zhao Guoyang pointed to the side of the stove with his hand and said: "To demonstrate, it's not simple, isn't there still a part waiting to be quenched, you can try it now." ” "Of course, I also have a small suggestion, that is, if you use tap water, you should leave it for at least a day, otherwise, the alkaline ions in the water can easily neutralize some useful elements in the workpiece."
Hearing this, Ning Xiaohong's face turned red.
In fact, she is clear about this problem, and she has also explained it to the workers below.
She had just spoken to the two workers and wanted to ask them why they were using tap water.
The worker's reply to Ning Xiaohong was that he was not fully prepared yesterday, and the tap water that had been placed overnight had been used up.
Ning Xiaohong thought that it was not a big problem, so she did not arrange for them to continue to add water.
Who would have thought that this small detail was also seen by Zhao Guoyang and brought up at this time.
At this time, the face of his technical section chief is a little unbearable.
However, from Zhao Guoyang's words, Ning Xiaohong also heard that this guy really didn't brag, and he was really proficient in the quenching process, otherwise it would be impossible to put forward so many suggestions.
Next, Ning Xiaohong's only doubt is whether she can solve the problem of quenching spots according to this Zhao Guoyang's method.
Seeing that Ning Xiaohong had been silent, Liao Jingsheng thought that she was a little embarrassed, so he personally ordered the two workers to suspend the quenching of the next workpiece.
"Comrade Zhao, I don't know what the additives you are talking about can we find now" Feeling Zhao Guoyang's extraordinary, Liao Jingsheng was also much more polite when he spoke to him.
"Don't worry, your workshop is available now" Zhao Guoyang pointed to a container in the distance and said unhurriedly.
"Director Liao, if I'm not mistaken, that container is filled with industrial salt, just add some to the quenching liquid, well, the ratio is about 10, not too much."
"In fact, the addition of salt to the water doubles the cooling rate without quenching and uneven quenching."
After speaking, Zhao Guoyang paused and added: "Industrial salt can be said to be the most ideal coolant for quenching, of course, if the workpiece produced by your factory does not need to be too hard, then it can be used."
Zhao Guoyang's words made Liao Jingsheng and Ning Xiaohong look at each other.
At this time, the two of them had long lost their previous contempt for Zhao Guoyang, and decided that he was a master who was very proficient in quenching.
Because there is a lot of theoretical knowledge because he said, Liao Jingsheng and Ning Xiaohong, the two former and current technical section chiefs, do not understand very well.
"Why are you two still stunned, don't follow Zhao Gong's words, go and prepare a 10 industrial brine to replace these tap water as quenching liquid" Liao Jingsheng looked at the two workers standing stupidly over there, waved his hand and shouted.
In Xiangyang Machinery Factory, Liao Jingsheng's words are nothing less than a holy decree.
After the two skilled workers received the order, they hurriedly ran to the side and prepared industrial brine.
Taking advantage of this gap, Zhao Guoyang turned his gaze to Ning Xiaohong and reminded kindly: "Section Chief Ning, since the quenching liquid you are preparing now is tap water that has not yet been placed, there are some alkaline substances in it. ” "I suggest that you put the workpiece that has just been quenched in and wash it after the industrial brine has been prepared in a while.
First, this can lighten the quenching spots on the workpiece; Again, it can also play a role in neutralizing alkaline molecules in water. ” "Uh, yes, I see, Comrade Zhao."
Ning Xiaohong was completely overwhelmed by Zhao Guoyang's professionalism and erudition, and she didn't dare to yell at him anymore.
Regarding the change in Ning Xiaohong's attitude, Zhao Guoyang was not surprised.
In his opinion, if Ning Xiaohong really keeps talking hard for the sake of her own face, it means that she is not useful at all.
As for now, it seems that this girl still knows how to advance and retreat, and she is a competent technical section chief.
Two workers quickly prepared 10 of the brine and carried it over.
Ning Xiaohong motioned for them to put the workpiece that had just been quenched into it, cooled it and washed it at the same time, and then secretly looked at Zhao Guoyang.
About ten minutes later, Zhao Guoyang nodded lightly to Ning Xiaohong and said, "Well, it's almost."
The workpiece can be taken out and ready for quenching. ” "Okay, I'll let them prepare now" Ning Xiaohong nodded vigorously.
"Oh, wait a minute."
Zhao Guoyang suddenly shook his hand again and said.
Under Ning Xiaohong's puzzled gaze, Zhao Guoyang smiled and said: "That's the case, this quenching method is the first time you have adopted it, and I am worried that the two masters are not very accurate in their grasp of time." ” "I'll do it myself this time, if you don't mind, please ask Section Chief Ning to help me do it."
"Don't mind, no problem" Ning Xiaohong was thinking about learning two tricks from Zhao Guoyang, so she naturally agreed.
Zhao Guoyang borrowed work clothes from one of the workers, changed them temporarily, and then put on thick industrial gloves.
Another worker also handed over the quenching workpiece to him in due time.
"Section Chief Ning, judging from the appearance, your workpiece should have a certain hardness requirement."
"Yes, yes, this workpiece is a chisel we made for a small farm tool factory, and the hardness is required."

Ning Xiaohong nodded again and again.
"Well, in that case, it must be a little less brittle to this workpiece.
Okay, just help people to the end, and help you add a tempering process. ” After finishing speaking, Zhao Guoyang did not ask Ning Xiaohong to do anything, and skillfully turned on the electric stove on the side and adjusted the temperature to a suitable number.
Not long after the workpiece was put on the stove, it gradually turned into a deep fiery red, Zhao Guoyang watched the change of the color of the workpiece intently, and kept turning the workpiece with a fixture.
Looking at his skillful operation techniques, the two workers on the side looked at each other.
One of them couldn't help but mutter: "It's really evil, this Zhao Gong doesn't seem to be as old as my son, how can he be so skilled, I think it's a few points stronger than our Ning Section Chief." ” "Who's to say it's not," another worker replied.
"You see when he flips, it's fast and steady, and he doesn't tremble at all, it's like a machine.
Awesome, it's amazing":
