Chapter 184: Sugar-Coated Cannonballs


Where did Zhong Ming think that a young man from the other party came out casually, and he said it rightly, and he couldn't help but have a feeling of powerlessness in his heart, this time I'm afraid it's really going to be messed up.

Shen Huan smiled and said: "So under normal circumstances, the hydrogen content of titanium alloy bolts is not more than 125PPM, and at present, titanium alloy material manufacturers can only control the hydrogen content of raw materials within 100, so the processing allowance left for strong parts manufacturers is only twenty-five, so in the processing process, if the increase in hydrogen exceeds this value, there may be problems." ” That Zhong Ming's eyes also widened, and he looked incredulous: "You, how do you know so clearly?"

” Shen Huan looked at everyone and continued: "In the process of titanium alloy bolt processing, the source of hydrogen absorption is mainly in the high-temperature atmosphere of pickling liquid, borylation treatment and thermal processing.

Of course, I won't go into details.

Let's talk about the second problem, titanium alloy bolts are very sensitive to surface defects and stress concentration, especially our high-strength titanium alloy bolts!

” At this time, not only Yu Tao was surprised, but Sun Chengming was also surprised, and they didn't expect Shen Huan to speak so thoroughly, obviously suppressing the representatives of the supplier.

Shen Huan continued: "Let's talk about the cracks of processing.

An important factor in the failure of titanium alloy screws is cracks, so cracks can not be produced during processing, but also to eliminate all cracks.

Especially in the cold heading and thread rolling process, cracks are most likely to occur, and they are very fine cracks.

For example, when rolling the wire, the threaded dental floss is not right, this situation has little impact on the steel bolt, but the titanium alloy bolt will cause the dislocation of the dynamic and static plate teeth, and the thread teeth will be squeezed out, so when the dental floss, it is necessary to observe whether the dynamic and static plate dental floss coincides under a 50 to 100 times microscope, and if it does not completely coincide, it will definitely cause cracks.

Of course, it is not easy for me to assert that this batch of titanium alloy bolts is cracked in this way.

Everything will have to wait for tomorrow's test to be conclusive!

” Sun Chengming also said in surprise: "Yes, I also think it may be the reason."

However, we still have to wait until tomorrow to know after the inspection, no matter what, Zhonggong, your factory must be ready to reprocess as soon as possible, otherwise the construction period will be delayed, and I am afraid that everyone will not be able to explain!

” Zhong Ming also knew that something might be wrong, but he still had a trick, that is, to find a way to make Sun Chengming and Yu Tao pretend not to see those black lines, of course, this depends on means.

So this Zhong Ming also rolled his eyes, and immediately said with a smile on his face: "What the leaders said is true, but whether there is a problem or not, it is still impossible to determine."

I think so, let's come together tomorrow morning and take a sample, okay?

” Yu Tao nodded and said, "Okay, these goods will be put here first, and we will test them tomorrow!"

” Yu Tao and Sun Chengming also left the warehouse, but at this time, Zhong Ming came with Yu Tao, Sun Chengming and Shen Huan.

How could Yu Tao not know what this Zhong Ming wanted to do, he stopped, looked at Zhong Ming who was smiling and said, "Zhong Gong, do you have anything else?"

” Zhong Ming rubbed his hands and said with a smile: "What, a few leaders, it's really troublesome for you to get this thing today, and I don't want to go, otherwise, I'll invite a few leaders to have a meal, and let's have a good communication!"

” Shen Huan also understood what this meant, daring to love this Zhong Ming wanted to use sugar-coated cannonballs to seal his mouth, and if he went to eat next, he would definitely arrange a series of cannonballs.

Yu Tao's face suddenly sank, and he said very seriously: "Zhong Gong, you are wrong, this is all our job, please don't use this method again, we don't eat this set."

You better go back and think about it, if this batch of goods is really unqualified, how should you remedy it, otherwise everyone will not be able to speak. ” Zhong Ming's face was gloomy, he knew that this time he had encountered soft and hard and did not eat, so he had to nod and say: "Director Yu is right, I will go back and call the leader to see how to deal with this matter!"

Then you're busy, I'll go back first!

” Yu Tao nodded, and Zhong Ming left in a gloomy manner.

Seeing this, Yu Tao smiled and said, "Xiao Shen, have you seen it?"

We must forbid to get up to the test, you have only been in our Jiangnan for a long time, and there will be many such people in the future, you have to withstand them, otherwise!

” Yu Tao didn't continue, but Sun Chengming on the side smiled: "Director Yu, I see, Comrade Shen Huan is more determined than us, don't you see that he wants to leave now!"

” Shen Huan said: "That, director, Brother Sun, I have to leave, and there are some personal matters!"

” Sun Chengming didn't know what was going on, but Yu Tao knew it, so Yu Tao nodded and said, "Xiao Shen, go quickly, it's okay here, I'm ready to go back from work!"

” Shen Huan hurriedly left the factory gate, took a taxi and rushed to Gao Mingyue's house.

Because of this incident, a lot of time was delayed, so Shen Huan also felt embarrassed, and called Gao Mingyue's house when he got into the taxi.

It was Gao Mingyue who answered the phone, and Shen Huan hurriedly said: "Mingyue, I'm sorry, I'm only coming out now, and I'll be there in about ten minutes!"

” Gao Mingyue looked at the time, it was only half past seven, she couldn't help but smile and said, "It's okay, it's only half past seven now, you arrived just right!"

” Shen Huan was relieved and said: "That's good, that's good, I'm afraid that I will make you wait for a long time, then I'll hang up!"

” Gao Mingyue smiled: "Okay, I'll wait for you downstairs!"

” When Shen Huan arrived downstairs at Gao Mingyue's house, he really saw Gao Mingyue in a white dress at a glance, standing at the entrance of the building waiting for him!

Shen Huan has always felt a little empty in his heart, because he knows that although Gao Mingyue has not mentioned it again now, it is obvious that she still has not let go in her heart.

For Gao Mingyue, Shen Huan is indeed her life-saving benefactor, and she has helped her family so much, so she always has such a peculiar emotion for Shen Huan, and she herself doesn't know why.

When he got closer, Shen Huan said embarrassedly: "Mingyue, I've kept you waiting!"

” Gao Mingyue's face flushed slightly and said, "It's okay, I just went downstairs too."

The meal has just been prepared, and you're just in time, so let's go upstairs!

” Shen Huan nodded, and went up the stairs one after the other with Gao Mingyue.

This is a very old building, the stairs are also extremely narrow, and the corridor is relatively dark, the conditions of Gao Mingyue's house are indeed not good, this is the epitome of the employees of Jiangnan Changxing Shipyard and several major shipyards in China, Shen Huan suddenly felt a bitter taste in his heart.
