No one knew what Qian Wenhua was thinking. They could only see the leader sighing and sighing!
"Work hard and think of ways to recruit a few smart people in the future so that you won't have to do nothing every day."
Finally, Qian Wenhua seemed to have accepted his fate.
He walked forward, and when he came to the factory, his expression became much better.
Although there are no processing tasks, the interior of the factory is quite tidy.
They had only walked half a circle around the factory when the hero doing the experiment had already arrived.
This is a hero who has been through thunder. He is definitely lucky to still have one leg left.
Unfortunately, the other leg was not saved after all, and half of his calf was amputated.
Qian Wenhua was the first to speak: "It's a bit short, can you put a piece on it? Or find something to fill it inside?"
Xiao Zhou said: "Okay, but it's a bit laborious to tighten these screws."
Xiao Zhou is considered the technical section chief in the factory. Although he is not very professional, he knows something about it.
But at this time, Cheng Daqi waved his hand very proudly and said: "We are a mechanical processing factory here. Isn't it easy to make this gadget? Just change it!"
Upon hearing this, Qian Wenhua laughed: "You can finally speak for once!"
Cheng Daqi said proudly: "When did I lose my ability to speak? Do you understand that good advice is offensive to your ears?"
Qian Wenhua couldn't stop laughing. He is also a leader. If you say good advice in front of the leader, it is offensive. Does this mean that I can't listen to good advice?
"Lao Cheng, let's talk less and do more." Xiao Zhou was a little worried for his leader.
"What did I say? There are things to do and words to say. As long as I'm not an old fool, can you still punish me for speaking?"
Cheng Daqi stared at Xiao Zhou.
Xiao Zhou was helpless, but he didn't dare to say anything.
Because he knew very well that as long as he was a normal person, he should not glare at him at this time, but should look at the dark-faced leader next to him.
"Leader, let's change it now." Xiao Zhou changed the subject.
Cheng Daqi was still a little unhappy. He felt that what he said was right.
The battle hero who just came here has half a leg shorter than Zhao Erwa.
In this way, the lower screw will not work, and you need to drill a hole on it and install a new screw.
However, things often don't go too smoothly.
Originally, I just drilled two small holes and tightened them with the original screws, so that I could do experiments.
However, no matter how hard the old workers who had just been called from the family area drilled, they just couldn't drill.
A group of people around were watching with wide eyes. Unexpectedly, the electric drill in the worker's hand made him feel lonely.
"What's going on?" Qian Wenhua asked a little confused.
After all, he is a scholar. His profession was originally a soldier, but now he is still half a soldier. He doesn't know much about industry.
But no matter how ignorant he was, he also knew that the drill bits in the hands of workers were not decorations.
But what is the situation now?
Can't the drill bit drill through such a thin layer of iron? No matter how you look at it, it feels weird.
"Old Wang, did you use a scrap drill bit? Don't be so frugal, use a good one." Cheng Daqi said anxiously.
Xiao Zhou also said: "I remember, didn't there be a lot of new drill bits?"
The worker Lao Wang was also confused. He knew that he was surrounded by leaders, and there was also a big leader.
If such a group of people asked him to do some work, could he bring over a waste drill bit? Isn't this just looking for trouble?
However, the drill bit he used really couldn't drill.
He simply put down the electric drill and looked at the drill bit first. It was intact and there was no problem.
Look at this strange thing in your hand. It's a thin layer, but it's really not thick.
But with such a small thickness, the drill in his hand couldn't drill?
"Where is this thing? I mean, where is the steel used?" Lao Wang finally asked in a puzzled tone.
Qian Wenhua looked at Yu Aiguo, who simply showed his hands and said, "I don't know. Ordinary people in rural areas can't buy steel, right?"
When Lao Wang heard this, he felt relieved.
"It should be a product of a small Sanwu factory. Those small factories have very complex sources of raw materials for steelmaking, and in many cases they can even smelt some alloys."
Seeing that all the leaders looked puzzled, Lao Wang explained again.
"They use scrap iron and scrap steel to make steel. Sometimes the scrap steel is of good quality and is directly blended into new steel."
"Sometimes the steel that is mixed with each other and refined cannot be drilled."
"I'll drill in another place and it should be fine."
As he spoke, Lao Wang picked up the drill bit again.
He turned on the power, waited for the drill to spin at full speed, then pointed it at another place and pressed hard.
As an old worker, Lao Wang still has a very steady hand.
When drilling holes with an electric drill, the most important thing is to have a steady hand.
Otherwise, where can the drill drill go down once it is stroked?
However, even so, the drill bit only rotates on the surface of the steel and cannot drill a small hole.
"What's going on? This isn't all made of high-quality steel, is it?"
Qian Wenhua frowned and asked immediately.
Lao Wang said calmly: "Impossible. The high-quality steel we are talking about is generally a special alloy, and only special alloys can't be drilled by drill bits."
"You definitely can't have too much of this alloy. If you can get a little, it's already pretty good."
"I'll change the place, just avoid the impurities here."
For ordinary steel, other metals doped in it, especially some metals with high hardness, are impurities.
This thing not only fails to improve the performance of the steel itself, but also reduces the overall plasticity.
Lao Wang has encountered many such situations.
For example, their factory used to make awnings, which are the kind that are placed above the windows and have a window-like awning. This thing is supported by angle irons.
The angle iron made by some small factories uses the most messy steel.
Sometimes when drilling holes for angle iron, we often encounter such a position that cannot be drilled. All we need to do is change the position and drill again.
Lao Wang thought that this was the same situation he was encountering now, so he was very calm.
However, what happened next made him stunned.
Because no matter how he changed positions, or even tried everywhere, he couldn't get into any place.
By this time, it was clear to everyone that this was not made of ordinary steel, but must be made of a special alloy.
"Lao Wang, how is the quality of this drill bit?"
Among the people who doubt life, there will naturally be great talents.
He is the director of a mechanical processing factory. Now he can't even make anything that is hammered out by hand using a thin piece of iron. Is this okay?
Lao Wang smiled bitterly and said: "I use the latest model of drill bit produced in China, which belongs to tungsten series high-speed steel."
Then Lao Wang briefly introduced what tungsten high-speed steel is.
Tungsten-based high-speed steel is mainly used in the manufacture of complex cutting tools such as drill bits, milling cutters, broaches, gear cutters, and taps.
This kind of tool steel is the most commonly used high-speed steel in my country because it has better overall properties.
That is, it has higher hardness, strength, toughness and heat resistance.
The cutting edge produced by it is highly versatile.
It is often used in the manufacture of various machine tool tools, taps and other complex tools.
However, its strength will decrease more as the cross-sectional size increases.
When Qian Wenhua heard this, he knew that there was nothing wrong with the drill bit.
Although he doesn't understand industry, he will be responsible for industrial management in the future.
Therefore, he has been reading materials recently to understand the development status of domestic industry.
Before liberation, the production of tool and mold materials in my country was almost blank.
In the early days of liberation, even alloy tool steel was all imported.
Therefore, there is no way to talk about its own tool and mold material system.
In 1952, with reference to the Soviet Union's national standards, my country's tool steel grade standards began to be established.
In the following thirty years, my country has achieved rapid development in the production and development of tool and mold materials.
However, these are all developments in the basic materials department, and we have been lagging behind in the development of special steels.
Especially in the processing industry, all the cutter bits, drill bits, slices, etc. used in high-performance machine tools are imported.
"It doesn't seem to be a problem with the drill bit!"
Yu Aiguo's eyes kept rolling before he spoke.
He was a little confused at first, but then he figured it out.
"Old leader, Zhao Erwa wore this thing before."
"Zhao Erwa is also one of the last batch of fighting heroes who came back and lost a leg."
"I remember when he was wearing it, he was jumping up and down, like a monkey, very restless."
"I saw that he was excited at that time, but I didn't notice that these iron boots should be of great help to him."
