In the factory director's office, Dong Xunfeng, Director Zhang, Yu Yibing and A Yu studied the treatment plan together.

"The test results are out, there are no problems with the formula and powder, I wonder if there is any new progress in the press and kiln?" Yu Yibing's face was faintly anxious.

"I'm also carefully checking the condition of the kiln, and I haven't found anything out of the ordinary yet." Dong Xunfeng reported.

"I've seen the press, and I didn't find any abnormal noise, including the platform and the rollers." Director Zhang also explained the situation to Yu Yibing.

"This problem must be dealt with as soon as possible, it has been almost 12 hours since yesterday, and everyone is still at a loss to come up with any remedial plan, so everyone has to roll up and get out." Yu Yibing frowned, and glanced at the faces of the three people with sharp eyes.

As soon as the words fell, the four of them fell silent again.

Li Yuxin wiped his sweat against the high temperature of the kiln, and at the same time checked from the dry belt of the plain kiln, he put a 30 cm long and 2 cm wide blank on the roller on the edge of the main transmission, and drew a few small black circles with a marker pen on the body, and a pile of white printing powder was placed in the circle. Li Yuxin began to use his ability to observe words and colors, and slowly followed this small brick all the way.

After 50 minutes of firing time, Li Yuxin did not find anything abnormal, and the printing powder in the black circle remained in its original state and did not fly out. Li Yuxin was a little puzzled, it stands to reason that it should be in the kiln, and the press part checked it three times without any abnormality. The sweat drops on Li Yuxin's head flowed down his cheeks, why is this, he must have neglected something, but what is it? Li Yuxin stood in the high temperature area of the kiln and began to meditate, and only when the temperature reached a certain high point would he have a flash of inspiration.

The clothes were soaked in sweat like water, and the thick jeans were also wet, Li Yuxin thought hard in the environment of 50 ° temperature, he recalled the experiments he had done over and over again, from the press to the kiln inlet, and then from the drying belt outlet to the kiln exit, repeated twice, he suddenly remembered that he had missed the kiln entrance to the drying belt. The plot that I thought could be ignored has now become a key entry point, and the iron rollers have been ignored by myself.

Li Yuxin slapped his head, hurriedly turned back to the Su Kiln into the kiln platform, and started a new inspection from the beginning of the platform. In order to accurately record the experimental data, he still used the method he had just tested to test it. When entering the 5th section of the kiln roller, he obviously saw a slight bump in the small brick, just this inconspicuous bump, so that he was interested, he quickly took off the brick and looked at the black circle on the brick, some of the printing powder in the circle flew out of the circle, this discovery made him interested, he recorded the number of the roller, and continued to test. There were noticeable bumps from 6 to 10, and 11 maintained a steady posture all the way to the dry zone exit. With some data, Li Yuxin's face was flushed with beautiful red clouds, and those beads of sweat the size of beans became extremely crystal clear in the blazing fire in the kiln eyepiece.

In order to verify this problem, Li Yuxin privately found Dong Xunfeng and told him the reason for his suspicions, and Dong Xunfeng saw that what he said was reasonable, so he followed him to watch his experimental process. Dong Xunfeng originally thought that Li Yuxin was releasing the cannon, but he didn't expect it to be true this time.

"Li Gong, you mean there is an abnormality in the roller? But how big of a problem can the iron roller be? It's not like a porcelain rod in the high, medium and low temperature area, which can be bonded and sintered, but this is an iron rod without a little temperature. Dong Xunfeng doesn't quite understand why there is a slight irregular arc movement, theoretically speaking, unless the transmission gear is stuck or the lack of gear oil will cause this result, but this probability is almost zero, because the gear has been soaked in the oil tank, and it is impossible to get stuck. However, the phenomenon in front of him made him feel confused, and he went to check the operation status of the oil tank and gears himself.

"This phenomenon is also the first time I have encountered it, so why don't you pull out one of the rollers here and take a look, so I can study it." Li Yuxin had never seen this situation, so he had to give him a suggestion, and he was not sure whether to adopt it or not.

"Okay, I'll pull one out and see." Dong Xunfeng is also a person who does not believe in evil, he just does what he says, and pulls out a roller rod with a "swish", and the action is very neat, without a trace of mud and water.

"How? Nothing. Dong Xunfeng didn't want anything to happen in his heart.

"You're pulling out the third root, so come with it, pull out the fifth root." Li Yuxin saw that the third hole on the roller table was open, and insisted that he try again.

"It's okay to pull it out, I don't believe in this evil!" After speaking, he grabbed the fifth roller with both hands and pumped it out, at first it was quite light, but when he pulled it into his mouth, he obviously felt a little bumpy, and it didn't seem to be so smooth. So he put more effort into his hands, and for the first time in his history, he used such force to draw the iron roller.

"What's the matter, can't you pull it out?" Li Yuxin asked suspiciously.

"It feels like I'm being pulled." Dong Xunfeng's face was a little ugly, this is really weird, is it still stuck? Li Yuxin saw that something was wrong, and hurriedly stepped forward to help, and the two of them finally pulled out the roller, squatted on the ground and began to ponder.

"Look, what's up here?" Li Yuxin suddenly shouted.

"Damn, why can't you get it down?" Dong Xunfeng thought it was rust or something, and thought that it would fall off if he wiped it with his hands, but now not only did it not fall, but he ignored him.

"Don't do it, you can't do it." Li Yuxin looked at him carefully and said to him.

"I can't do it? What do you mean? Dong Xunfeng looked at him blankly.

"It's not just a thing, it's a magnet! Stainless steel magnets. Li Yuxin said as soon as he said it, and Dong Xunfeng was suddenly stunned.

At this time, Dong Xunfeng's heart was galloping, and the grass and mud horses were bombarding in turn.

He hurriedly reported the situation to Director Zhang and Yu Yibing, but called the kiln squad leader and the kiln inspector to come over to help, and pulled out all the rollers that Li Yuxin pointed out to check. Yu Yibing ordered to stop the bricks from the plain kiln, and the press was on standby, waiting for the notice.

"What's going on? How are they all magnets. Director Zhang frowned and squinted, looking embarrassed.

"Pull out the roller first, and I'll find someone from the roller factory to come and help deal with it." Yu Yibing directly contacted the roller company with a phone call to deal with the matter. The other party promised to bring special equipment to help, but the cost had to be reimbursed by the factory, Yu Yibing agreed to their request, just emphasizing that they should be fast.

At this time, it was already 12:20 noon, Li Yuxin's face did not have the slightest color of excitement, he was thinking about a question: This is definitely not an accident, someone must have done it on purpose, but why did he do it? Is it just fun? It's too ruthless, it's really not ruthless, it's both secretive and professional, and people without a little common sense can't do it at all.
