Police order

Chapter 565 Exploring the Round Steel
City C.

"Hurry up! Hurry up! Hurry up!" Squad Yan sat on the back seat of the police car and beat the driver's seat with his hands, "Hurry up! Why are you afraid of turning on the police lights! Hurry up!"

The driver is Captain Li. He really doesn't have the habit of driving fast, but at this moment he changed his normal routine and pushed the accelerator to the end: "Squad Yan, don't rush, the speed of the car in these days is so frustrating!"

"It's my fault, I shouldn't be driving this! Come on, hurry up." Team Yan looked at his watch, "We don't have much time left."

"Can't you contact the Harbor Superintendent and ask them to help stop it?"

"A ship of 10,000+ tons is still a foreign ship. If there is no evidence, just block it? I don't have the ability anyway." Yan Detachment looked at the watch again, "Hurry up and have a look."

"How do we check?"

"Let's go and talk about it. I'm looking for the old iron. He brought the equipment. Hurry up, we have to go there first."

"it is good."

Just half an hour ago, Team Yan suddenly received a call from Yan Yu.

Lu Ling obtained important information from Shenzhou. The X Iron Factory in City C smuggled gold into the exported industrial round steel.

After investigation, Yanyu found that a batch of industrial park steel from the iron factory had recently entered the port, so he immediately contacted Yan Detachment and told Yan Detachment that it must keep it secret at this stage.So, the two groups rushed to the scene quickly.At the same time, the Yan detachment also found professionals to go together with the equipment.

The parties were very quick, and after about half an hour, they all arrived at a warehouse at the port.

"The gold is hidden here, it's hard to find." The person who spoke was Lao Tie, a technician from the iron factory, and a person trusted by the Yan detachment.He held a scanning gun and a small hammer in his hand, with a look of embarrassment on his face.

"Can't hide it? Master Tie, can you check and try?" Yan Yu pointed to a pile of round steel in front of him.

There is an obvious "iron smell" in this warehouse, which is very strong, and both Yan Yu and Kou Yuyang are not used to it.These round bars are a bit thick, about as thick as an adult male's thigh, giving people a heavy feeling.

"Inspect?" Lao Tie pointed to the round steel piled up in front of him, "How to check? This is 250*8240 40GR round steel. This one weighs more than three tons. How do you check it? If you want to check, you have to lift one by one. Get up and check."

"Hang them all up?" Team Yan immediately knew the seriousness of the problem.

There are about 1000 round steel bars in it, and according to Laotie, there must be more than 3000 tons. 3000 tons of steel is not a lot for sea transportation, but if put on a truck, it is enough to pull 100 vehicles.Each one is more than 3 tons, and it is completely impossible to move it by manpower.

"More than 3 tons." Yan Yu also noticed the difficulty of the problem.

The intelligence is only heard that there is technology here that can stuff gold into round steel for smuggling, but no one knows if there is any in this batch, and even if there is, they don't know which one is in it.

"Old Iron," Yan Detachment asked, "is it possible to hide gold in this round steel? I think it is all cast in one piece. It is impossible to put gold in the casting, right?"

"That's definitely impossible," Lao Tie shook his head, "Private individuals don't have this technology, and it's impossible for large factories to specialize in this technology. Processing round steel of this level is no joke."

"Then how is it possible to put gold in this solid steel?" Team Yan took out his baton and knocked on the steel, which made his hand hurt.

"What's so difficult about this? Isn't it enough to turn on a lathe? Put on the turret machine, put on the U drill for turning, and just dig a hole out of the round steel. The 40GR round steel is easy to dig out. After you pull it out, you can stuff it with whatever you want. .” Old Tie saw the plan at a glance.

In the eyes of ordinary people, steel is a representative of high strength, but in the eyes of old iron, it is just a material, and it is an easy-to-process material.

"Then how do you make up your mouth? Isn't that obvious at a glance?" Yan Detachment was a little disbelieving.

"It's not difficult. It's easy to carve with a machine tool. Cut a piece of steel that fits perfectly with the joint. No welding is needed inside, just a little glue, and no seams can be seen unless it is inspected by a machine." The old railway said, "If I For the operation, I don’t cut from both ends of the round steel, so what’s the technical content? I just cut the hole from the side, and it’s too simple to make a big hole with this diameter of round steel.”

Lao Tie told everyone about the current Jingdiao machine tool. First, he took out a big hole, then stuffed enough gold, and the next step was the filling process.The Jingdiao CNC machine tool can guarantee the accuracy within 1 wire, and it is difficult to insert it, because there is almost no air leakage, and it is likely to have a special opening with a diameter of several wires for ventilation. (Note, 1 wire is 0.01mm, and the diameter of hair is generally 6-10 wires)
Moreover, because the sides are not polished, even if there are a few traces of error, it is almost invisible.

"Can you judge whether there is gold by distinguishing the weight?" Kou Yuyang asked.

"Impossible," said the old railway, "there must be errors in this basic material. Even if the error is five thousandths, there will be a difference of more than ten kilograms. Although gold has a large specificity, it is impossible to measure 20 kilograms of gold." Come out. Besides, I’m worried that your funds won’t allow you to weigh the 1000 round bars once.”

"It's too late." Team Yan was a little anxious.

The current information cannot be said to be accurate, but it is already very precious.However, in the face of this mountain of round steel, no one could do anything.

One piece weighs more than 3 tons, and it cannot be moved by manpower. If you borrow machinery, you need to have a special place for secondary storage. The cost of this is staggering.

"So, old man, do you have any way to find out the problem here as soon as possible?" Team Yan asked.

"Yes," the old railway said, "it's enough to drop it. Hang it up one by one, and drop it on the iron plate from a height of about one meter. But any processed ones will definitely disintegrate."

"Hang up and fall one by one?" Lao Yan wanted to cry, "How much is this one?"

"About twenty thousand."

"Can it still be sold if it falls?"

"That's enough."

"." Team Yan was speechless for a long time.

"There is another way," Lao Tie Dao said, "Ultrasonic flaw detection, unless there are really no cracks there, it can still be detected. Of course, even ultrasonic flaw detection has to be inspected one by one. Slow down a little bit. Now all the round steel is piled up together, and there is no way to check."

Now all the steel is next to each other, and when the ultrasonic wave hits, it is impossible to know where it can be bent.

"We don't know if there is any gold in this batch, so we can't startle the snake yet." Yan Yu reminded.

The reason why everyone came here so quickly is to find a better solution, and it's best not to disturb this place.

Yan Yu only has her and Kou Yuyang here, Yan Detachment only has him and Li Brigade here, and there is the old iron that Yan Detachment specially called over.

There are only five people in total, and no one has noticed them yet.

However, moving steel is a big movement. Once 3000 tons of round steel is moved, no one can cover it, and X Iron Works must know.If there is no smuggling in this batch, then this channel must be avoided in the future.

"Are police dogs useful?" Captain Li asked.

Yan Detachment glanced at Lao Tie, who waved his hand: "Don't ask me, I don't know about this, and I don't understand police dogs."

"I need to find a professional to ask." Yan Detachment obviously doesn't trust the police dog team on their side, and looked at Yan Yu, "Do you know any police dog experts?"

"I know someone," Yan Yu said, "It's trustworthy."

"Okay, let's get in touch."

Yan Yu nodded, and called Captain Mengting from Shaanxi Province, and contacted the police dog expert.

The answer was difficult.

If there is a lot of sweat left on bare hands when stuffing the gold and installing the carved plates, the police dogs can still hope to smell it.If you're wearing gloves, it's almost impossible to smell it.The main reason is that the "iron smell" here is too strong, and the police dogs will be buzzing when they come in.

"Do you need gloves to install this?" Yan Yu asked Lao Tie, "Is it because you can't wear gloves to ensure accuracy?"

"How is it possible?" Lao Tie shook his head, "Who dares to touch it without gloves. Some of the corners of those carved plates are sharper than knives. Not only do you need to wear gloves, but you must also use professional gloves."

"That's troublesome, gold itself has no smell at all." Yan Yu and Captain Meng Ting exchanged a few words and then hung up the phone.

"Are you desperate?" Yan Detachment looked at Yan Yu.

"I don't suggest that," Yan Yu shook her head, "Lu Ling told me that this Gan Hong, he has deliberately pointed out clues to the police several times. Before, he said that he heard that there was a murder case in a certain river. The Shenzhou police spent several days digging up the corpse, and spent more than [-] yuan just to find the frogmen. Fortunately, Shenzhou has money, otherwise it would be a big trouble."

"Can't you beat him?"

"How dare you? Besides, Gan Hong said that he had heard about it, and Gan Hong himself said that he was not sure. What can we say? It's just that he has to investigate after he said it. It's really disgusting. However, Lu Ling told me that this time It should be true, Lu Ling's polygraph ability is still good."

"That being the case, let's find a crane and try to use those ultrasounds one by one. We can still afford the expense."

"But I really don't know what the probability is. If it doesn't, it will be troublesome to startle the snake." Yan Yu looked at the steel and felt powerless.

The police often encounter such difficulties in handling cases. Once some difficulties arise, it is bound to be a dead end.

"If Lu Ling was here, what would he do?" Kou Yuyang asked behind Yan Yu.

"We talked about the general situation before we came here, and he can't do anything about it," Yan Yu said, "If it's several hundred kilograms, we can still try to manually carry it and check some of it."

"That's really troublesome, there are so many round steel." Captain Li also sighed.

"By the way," Yan Yu suddenly thought of something, and asked Lao Tie, "Master Tie, I remember something called a metal composition detector, can it be used?"

"This?" Lao Tie directly took out a small machine in his hand, which looked like a large electronic thermometer, "This won't work, even jewelry with gold and silver may not be able to detect the silver in it, this is mainly to measure the surface of the metal of."

"Then is there anything that can penetrate metal?" Yan Yu asked again.

"Then I don't know, we don't usually use it."

"Then let me ask for help." Yan Yu thought for a while, then looked at Kou Yuyang, "Who here is a science student?"

"Ye Wenxing, he studied civil engineering."

"Ah yes!" Yan Yu hurriedly called Ye Wenxing.

Two days ago, Ye Wenxing and Shi Qingshan had gone to Beijing to attend the training of the World Police Association.

After Ye Wenxing answered the phone, after listening to Yan Yu's words, he chatted with the person next to him.

"Don't tell anyone who has nothing to do with this matter." Yan Yu hastily instructed.Although there is a high probability that Shangjing has nothing to do with this place, but we still need to pay attention to it.

"It's not outsiders, it's your senior brother Baisong." Ye Wenxing said.

"Ah? My senior brother? That's okay, let's talk." Yan Yu nodded, "By the way, why are you two together?"

"Oh, he sparred with Qingshan before, and he was beaten...cough." Ye Wenxing said, "Team Yan, wait a moment, I'll ask him."

Soon, Ye Wenxing gave Yan Yu an answer: "X-rays are fine, you go to the banning team, ask them to borrow a portable X-ray machine, and punch these round steel."

"The portable one can penetrate the entire piece of round steel?" Yan Yu was a little surprised.

"That's impossible," Ye Wenxing said, "Just now Bai Chu said that if it is ordinary steel that can penetrate 40mm, it is estimated that the piece they carved on the outside cannot be so thick, and such a thickness will seriously affect the size of the space inside. "

"If you want to say that, you have to hang up the round steel one by one to check."

"Then I don't know. There is no good way. It is impossible to have a machine that can penetrate all the round steel in your place. How powerful it is."

"Okay, thank you!" Yan Yu hung up the phone, still thinking it was a good idea.

Because the round steel is very heavy, that is to say, it is stacked two or three layers.Yan Yu believes that if there is really gold in the round steel, then the fewer people who know about it, the better. It is impossible for even the transport workers to know about it.So when stacking here, it is impossible to deliberately put the gold ones below.

Even, if an insider came to oversee the work, there is a high probability that the gold ones will be placed on the upper layer to prevent the bottom ones from being squeezed and exposed.Each one weighs more than three tons, and the strength underneath is too great, and the carved steel that is filled in later is prone to slight displacement.On such a round steel, if the outer steel is squeezed in half a millimeter (50 wires), it is easy to see with the naked eye.

The biggest difference between a portable X-ray machine and an ultrasound is that it will not be disturbed by others.During ultrasonic flaw detection, because the steel is close to each other, after the ultrasonic wave enters the steel, it cannot be controlled, while X-rays can only detect a certain fixed area.

Yan Yu didn't know that X-rays could penetrate such thick steel, but after knowing this solution, she had to try it.

"Does your anti-poison detachment in City C have this machine?" Yan Yu asked.

"Yes, a set of 10,000+, just configured not long ago." Yan detachment said, "But it's just one set, I don't know if the time is too late."

"That has to be delivered too, hurry up!" Yan Yu said immediately.

"Okay, I'll arrange it." Team Yan immediately took out his mobile phone and walked towards someone he trusted.

"Time is tight," Captain Li looked at his watch.

According to regulations, these steel materials will start to be transported onto the ship in another four hours. If these people are still here to investigate by then, they will definitely not be able to cover them up, and they will definitely be discovered.

"Fortunately, City C is still rich." Yan Detachment was a little thankful.

The main function of this kind of X-ray machine is to check the concealed drugs in the car.Some people will hide the poison in the channel steel of the car or in the main structural steel, and it will not work without this thing.

"Hope it works wonders."
